Optimus Prime (TFP) (ENG)

As Optimus Prime, he is a very stern and serious leader, who doesn't tolerate jokes and, as described by Bulkhead , never cries or loses his cool. But when Optimus loses his cool, it is because of the Decepticons who annoy him the most. This was shown when Starscream stole the three Omega Keys from the Autobot base, causing Optimus to get angry skyward when Starscream escaped with the keys. It is shown that Optimus doesn't like parties either, but he does attend small ceremonies. At the same time, Optimus has all the qualities of a good leader. He is an excellent tactician, knows how to prioritize, and cares about his subordinates. Prime can be harsh, but he is never cruel; he is merciful and ready to give even a Decepticon a chance at life, he will never raise a weapon on a defenseless person. War is a heavy duty for him; if there is even the slightest chance to settle a problem peacefully, Optimus is sure to try to take advantage of it. Can be a very caring bot, making sacrifices to ensure the safety of the team and their human allies; even he is willing to sacrifice himself to save them, Earth and Cybertron. Optimus also has a highly developed sense of honor and loyalty. However, it has been shown that Optimus is willing enough to abandon his code of honor and resort to Decepticon tactics to stop Megatron. The tasks of protecting the humans and stopping the Decepticons at the same time should have brought him to his knees, but he did not give up. Optimus would even risk his spark to win the Decepticons over to the Autobot side, including Dreadwing and Breakdown.

Prime is approximately 9 meters tall. The body is made of a cobalt super alloy, which makes it resistant to almost any impact or explosion. Also, when in robot mode, he has windows on his chest, behind which is a camera that holds the Matrix of Leadership. Optimus has a gray face, a blue helmet, and three antennae on each side, two blue, the rest gray, meticulously detailed and made up of multiple plates and layers of parts on top of each other. Optimus has two spherical bases for the antennae with dark blue coloring around them. He has a red chest with windows from vehicle mode and a dark gray stripe on both ribs. He has large shoulders that overlap his arms. The two wheels in the back are held up by his smoke stacks. There are four wheels at the back of his legs. After the upgrade, his appearance includes windows on his chest, a blue helmet, and a red color scheme all over his body, except his legs are gray like his face and arms. His appearance has also become bulkier and more muscular. Optimus' helmet had thicker antennae, his arms had noticeable bars, and the upgrade included a jetpack. He also became 1.5 meters taller, surpassing even Megatron in height.

On Cybertron, a truck; upon arrival on Earth scanned a red and blue tractor-trailer similar to the classic Freightliner Coronado model. Can attach a trailer to the rear blue section. Optimus can go to maximum overload, allowing him to move faster than a normal truck. After the update, he now has an alternate mode similar to that of an experimental all-terrain expeditionary combat vehicle designed and built by the US Army's top division engineers.

Powerful double-barreled (later single-barreled) Ion Cannons, Energon Blade, Star Sword, Machine Gun, Solus Prime Forge, Energon Minigun. He is the custodian of the Matrix of Leadership, which contains all the power and wisdom of the Primes accumulated over millions of years

In the early days of Cybertron, Orion Pax looked up to Megatronus as a mentor. The two were close and great friends, almost like they were brothers. Megatronus changed his name to Megatron before he went with Orion to the high council to explain his ideas. When Orion gave his speech to the high council to defend Megatron, he was chosen to be the new Prime. Feeling betrayed and his jealousy towards Orion, Megatron severed all ties with Orion and the council as he declared war on Cybertron. Eventually, Orion had reached Primus, the core of Cybertron, in order to undo the damage caused by Megatron. He was given the Matrix of Leadership to Orion making him into Optimus Prime.

Years later, Optimus fought Megatron again when he attempted to stop Megatron from sending an undead army from Cybertron to Earth. During the battle on the Space Bridge, Optimus was close to getting killed by Megatron until Starscream contacted Megatron. Megatron told Optimus 'Ah... misdirection, Optimus. You would have made a fine Decepticon!' Optimus told Megatron 'I chose my side!' before blasting Megatron into the air. After the battle, Megatron was caught in the explosion of the space bridge and Optimus presumed he'd been killed. Though Optimus did mourn over his former friend, Megatron was later revived after taking over Bumblebee's body in a successful attempt to get back to his own body. Optimus was surprised when Megatron prevented Starscream from blasting him in Out of His Head.

In One Shall Fall, Optimus faced Megatron head on after Megatron injured Raf with a blast of Dark Energon near a volcano site. Optimus and Megatron brutally fought each other for quite some time until Optimus seemed to get the upper hand when Megatron seemed to get weak. Optimus was able to get Megatron on the ground and was close to killing him until Megatron suddenly regained strength. The fight ended in Megatron getting the upper hand, with Dark Energon coursing through him to give him strength, and was about to kill Optimus. Though Bulkhead, Arcee and Ratchet came in time to save Optimus. After learning that Unicron was the very core of the Earth, Optimus decided to face Unicron's manifestations alone but was soon backed up by the other Autobots. When a large manifestation of Unicron was about to step on Optimus, Megatron destroyed the manifestation, thus saving Optimus. Optimus eventually agreed to team up with Megatron to stop Unicron from destroying Earth. As the Autobots and Megatron head for Unicron's spark chamber, Optimus and Megatron worked together in destroying some of Unicron's anit-bodies. Unicron even attempted to control Megatron, but Megatron merely saved Optimus from being attacked by one of the anti-bodies. Optimus and Megatron made their way inside Unicron's spark chamber. This, however, ended in Unicron controlling Megatron entirely and Optimus losing the Matrix's energy, along with his memories, to destroy Unicron's spark. Megatron woke from being unconscious and walked towards Optimus as he had draw his sword out. However, when Optimus saw Megatron, he asked where are we Megatronus? Megatron was surprised and realized Optimus had lost his memory, which he took this advantage by helping Optimus to his feet and brought Optimus back to the warship, where Megatron addressed to the other Decepticons that Orion Pax was one of them.

While Team Prime divised a plan to rescue Optimus and restore his memories, Megatron was deceiving Orion into believing he was a Decepticon and that the Autobots were their enemies. Megatron explained that that Decepticons were named for spreading the truth and if speaking was deception, then they were gladly guilty. Megatron gave Orion his own place to work on working the Iacon database for secret hidden relics that, as Orion explained, were hidden away for later use. When Orion showed Megatron about Starscream, Megatron lied by stating Starscream was deceased.

After an incident where Starscream actually made his way into the warship, he went in Orion's room where he told Orion about Megatron. Orion did not believe what Starscream said and was engaged in a conversation until a couple of Vehicons chased Starscream out of the warship. Megatron went to check on Orion and explained to him that Starscream was a traitor who went to the Autobot side. Megatron leaves Orion to his work and Orion does as his lord wishes.

When Orion was researching about Optimus Prime, he eventually came to a discovery that he was Optimus Prime. When Megatron came to check on Orion again, he told Orion that they were tracking his activities as he pushes a button that shows Orion's research on Optimus Prime. Orion begins to question Megatron and eventually tried to delete his work but unfortunately for Orion, the data was saved. Megatron then ordered guards to watch Orion and threatened to kill Orion if he did not comply. Orion was beaten by the guards and eventually blasted them to death when he accidentally transformed his hands into guns.

Orion soon realized on his own that his place was with the Autobots and tried to take on Megatron himself. Orion was defeated by Megatron and was close to getting killed until Arcee jumped Megatron and saved him. Once Jack restored Orion's memories, Optimus grabbed onto Megatron's sword when the latter came close to jumping at Optimus. Optimus punched and trounced Megatron before he escaped with his team back to base.

After the hunt for Iacon relics, the arrival of Smokescreen, Optimus getting the Star Saber, and learning of the Omega Keys, Optimus battled Megatron with the Star Saber, as they fought Optimus again claimed to be nothing more than a simple soldier. Eventually, Optimus obtained all four Omega Keys. Though Megatron used the Autobots' human friends to trade for the Omega Keys. Optimus had no choice, but to destroy the Omega Lock as Megatron was using it to cyberform Earth. When Megatron ordered the destruction of their former base. Optimus remained behind while everyone left and was caught in the explosion.

Though sometime later after Optimus was saved by Smokescreen, Smokescreen was able to retrieve the Forge of Solus Prime and used it for Optimus to regain a new body. Optimus flew to Darkmount in his new jetpack and saved Ultra Magnus from Megatron. They air fight and in it ended with Optimus knocking Megatron into the fusion cannon's power core, repeating his old phrase "Megatron! Be gone!" In the last episode of season 3, Optimus faced against Megatron to stop him from cyberforming Earth again. Megatron was able to kill Bumblebee in the process, which enraged Optimus, who then proceeded to attack Megatron violently. Megatron was able to get the upper hand and was close to terminating Optimus as well, but he was stabbed with the Star Saber by the revived Bumblebee before he took the chance. As Megatron's lifeless body fell off the platform towards Earth, Optimus showed little signs of remorse as he watched Megatron fall.

In Predacons Rising, Unicron revived Megatron's body as his vessel. When Optimus returned from retrieving the Allspark, he fought against Unicron. During the battle Optimus attempted to remind Megatron of their old alliance, which saved Earth from Unicron's wrath. Despite Optimus's efforts to reach Megatron, Unicron pointed out that while Megatron could hear Optimus, he could not help him as he was being tortured by Unicron. After Unicron's Anti-Spark was sucked into the container trapping him, Megatron was freed from his torture. Optimus said nothing as Megtron denounced his return to the Decepticon cause as Starscream tried to convince his master to regain command over the Decepticons back. Optimus was initially surprised when Megatron explained that he had finally learned the true meaning of oppression and had lost his taste for inflicting it on others. Optimus then watched thoughtfully as Megatron disbanded the Decepticons and he flew off to presumed banishment. Before becoming one with Primus, Optimus noted to the Autobots (including Knock Out) that Megatron still has the capacity for change.

Megatron is like a long lost brother to Optimus.

Bumblebee is one of Optimus Prime's scouts. He is also one of Optimus' close friends. In Masters and Students, Bumblebee tagged along with Optimus to investigate Decepticon activity. After defeating Skyquake, Optimus commended Bumblebee for doing admirably. When Optimus had amnesia (after sacrificing the Matrix of Leadership's energy to destroy Unicron's spark), he reverted to Orion Pax, who looked back on Bumblebee. Bumblebee was saddened that his leader did not recognize him as Orion just gazed back before he left through the portal. Bumblebee helped the Autobots in mission to restore Optimus's memories, which proved successful as they were able to restore Optimus to his normal self and celebrated back the base. When M.E.C.H stole Bumblebee's T-cog, Optimus related to Bumblebee losing part of himself. Incapable of transforming, Bumblebee persuaded Bulkhead in letting him tag along on a mission, though Bulkhead states that if Optimus found out it wasn't his idea. This ended in Bumblebee chasing after Knock Out and plunging off a cliff. Back at base, Optimus restricted Bumblebee until they were able to retrieve his missing bio mechanism. Bumblebee discovers M.E.C.H's location, provided by Agent Fowler. However his T-cog was shot by Starscream, who made a temporary alliance with M.E.C.H., Ratchet was able to fix Bumblebee's T-cog, but states the damage was severe. When Bumblebee transformed and took Raf on a drive, Arcee commended Ratchet for fixing Bumblebee's T-cog and Optimus also stateed that is not all that Ratchet repaired. In Crossfire, when a weakened Megatron asked Optimus if he planned on terminating him later or right at that moment, Bumblebee looked at Bulkhead in shock, then Optimus pulled out his gun on Megatron.

When Bumblebee tried to give Optimus the Star Saber in the final battle for Earth, Megatron blasted him, leaving Bumblebee's body to drift in the Omega Lock's cybermatter. Outraged over his scout's death, Optimus punched Megatron until he was able to get the Dark Star Saber and fling Optimus off the Lock's platform. Just as Megatron was about to finish Optimus off, Bumblebee was restored by the cybermatter and used the Star Saber directly into Megatron's spark, which his lifeless body fell from the Omega Lock downward to Earth. Bumblebee helped Optimus climb up as the rest of the Decepticons escaped. After the Autobots used the Omega Lock's energy into the core of Cybertron, they went back to base where Optimus gives a speech about how they are going to miss Earth. Ratchet decided to stay behind with the kids as consultants. Bumblebee gives a last goodbye to his partner, friend Raf before going home with the others. In Predacons Rising, Optimus promoted Bumblebee to warrior after his efforts in killing Megatron. Optimus "knighted" Bumblebee by patting him on the shoulders with the Star Saber. Before the party had begun, Optimus told his team that he must retrieve the AllSpark from outer space, if they ever hope to fully restore Cybertron. Bumblebee insisted that they go and get it back, but Optimus says that they can't leave Cybertron with their fugitives, Starscream and Shockwave, still on it, including Predaking. Optimus left with Wheeljack while Bumblebee filled in for Optimus as leader. While finding Predaking, Bumblebee said he was just scouting than leading. When they encountered Predaking, they explained to him about two new Predacons on Cybertron. Optimus came on time and defeated Unicron. He trapped Unicron inside the AllSpark's container. Before becoming one with Primus, Optimus told his team, including Knock Out, that they acted as a Prime. Bumblebee promised to keep the peace in Optimus' memory. As the team sadly watched their leader fly into the Core, they were amazed by the Sparks that flew out, including Optimus' spark. Optimus and Bumblebee continued their relationship in Transformers: Robots in Disguise where Optimus led Bumblebee back to Earth to face a new threat.

Much like Alpha Trion did for him, Optimus mentored Bumblebee on his path. Optimus is a father figure to Bumblebee and fights by his scout's side.

Optimus knew Ratchet long before the war for Cybertron and the pair became very close friends. Ratchet stood by Optimus' side after he and Megatron severed all ties, starting the war for Cybertron. Optimus would often seek console from his old friend on many occasions during the war, both on Cybertron and Earth. While their ideals often clashed, Optimus always had a high opinion of his chief medic. Optimus was often very protective of his old friend, often advising him to leave and save himself when fighting appeared to intense in the field. In turn Ratchet would often refuse to leave his commander's side. Ratchet is like a brother figure to Optimus.

When Optimus lost his memories after sacrificing the Matrix of Leadership's energy to destroy Unicron's spark, Ratchet worked hard with the Autobots and humans to get Optimus back. Their plan worked and Ratchet informed Optimus that it seemed like it was their darkest hour but through it all, Optimus was a true Autobot inside and out.

When Optimus destroyed the Omega Lock on Cybertron, Ratchet was shocked at Optimus as he stated to him that it was their only way of restoring their home. As the rest of the team left through the groundbridge to different locations to avoid being captured by the Decepticons, Ratchet and Optimus shared a seemingly last moment where Ratchet questioned Optimus about where he would go. Optimus decided to remain at the base and before Ratchet left, he stated that he would never imagine it would end like this. After Ratchet left, Optimus stated to himself that he didn't expect it either. Ratchet seemed to lost all faith as Optimus was not there to reunite with the Autobots, even with Ultra Magnus as their temporary leader. However, thanks to Smokescreen, who saved and restored Optimus in a new body with the Forge of Solus Prime, the Autobots were victorious in destroying the Decepticon citadel on Earth and they all celebrated back in their new base.

Ratchet showed Optimus his latest work on his Synthetic energon research, which Optimus thought it was a wise decision.

In Predacons Rising, Ratchet states to Optimus that he's the one that Ratchet cares most about before Optimus became one with Primus. As the sparks flew from the core, the Autobots were astonished as a red spark (possibly Optimus) shines out. Ratchet is Optimus's best friend and Ratchet deeply cares about Optimus.

Arcee is one of Optimus' most reliable soldiers on the team. She's one of his close friend, next to Bumblebee, Bulkhead and Ratchet. In Scrapheap, Optimus and Arcee ventured to explore more about their Arctic find. When they were ready to go back to base, with no findings, Optimus was unable to contact Ratchet for a ground bridge. With their core temperatures at the danger zone, Optimus suggested the need to seek shelter. Optimus and Arcee tried to keep themselves functional by talking. Arcee suggested that they play a game called "who screwed things up back at base." Optimus tried to remain positive by pointing out that the problem could have been a simple malfunction, while Arcee stated it could have been caused by Bulkhead. Optimus pointed out that Bulkhead's size isn't compared to his inner strength, and that "one should not be measured by size alone." As Optimus and Arcee prepare to accept their end, Optimus talks to Arcee about joining the Allspark together. His speech was cut short as Arcee stretched out her left hand to hold Optimus's left hand and Optimus did the same as they held each other's hands as they prepared to freeze to death.

Arcee's loyalty to Optimus is strong and without question. When Optimus had amnesia (after he sacrificed the Matrix of Leadership's energy to destroy Unicron's Spark) and was taken to the Decepticon warship with Megatron, Arcee was able to get on board the warship. In her attempts to find Optimus, she completely took out several Vehicons in her path. Before she could reach to Optimus, she was ground-bridged off the Nemesis by Soundwave. However, after a mission with Jack to go to Cybertron to restore Optimus's memories, Optimus returned to his normal self after Jack downloaded his memories in the Matrix of Leadership and Arcee was pleased that her leader was back when the Autobots retreated back to their base.

When Nemesis Prime attacked Agent Fowler and knocked Arcee unconscious in its vehicle mode, Arcee began to feel suspicious when the incident seemed like it was Optimus. However, when Optimus revealed that he came back from scouting an energon mine with an energon crystal in his hand, the Autobots stand down as Arcee walked to Optimus to apologize to him.

In the ending of Predacons Rising, Arcee suggested that the Autobots turn to Vector Sigma again when Optimus was about to sacrifice himself to restore Cybertron but it wouldn't work since the Matrix would be gone forever once it merged with the AllSpark. Arcee and the others sadly watched as Optimus sacrificed himself to go inside the Well of AllSparks but they were all excited when sparks began to fly from the well.

Arcee and Optimus both have a platonic friendship. They would often hang out and talk to each other on occasions. Arcee calls Optimus by his name and sometimes refer him as a Prime. She sometimes consults with Optimus and Optimus is one of Arcee's friends who tries to keep her calm. Optimus relates to Arcee's feelings and tries his best to make her feel better. Arcee sees Optimus as a noble leader and friend to have. Arcee helped Wheeljack and Optimus helped Ultra Magnus when they were feeling impaired in the team. This would show that both Optimus and Arcee know how to support their comrades. In Sick Mind, Arcee told Ratchet she would risk her own life for Optimus anytime, anywhere, which shows she would not hesitate to do anything that will make Optimus feel well. In Minus One, as Ultra Magnus went with Wheeljack and Bumblebee, Arcee secretly watched Optimus. This shows Arcee cares the most about Optimus's well being. Arcee also knows the rules of being a Prime, as she points out Optimus not being the party type or never runs away from a fight. Arcee looks up to Optimus as an older adult figure, since she appears much younger than him. Arcee and Optimus respect each other as soldiers, friends, and family.

Ultra Magnus was Optimus' key lieutenant during the war for Cybertron. When Optimus was gravely damaged, Ultra Magnus arrived on Earth where he reassembled the Autbots with the exception of Optimus and Smokescreen. When his plan to launch an attack on Darkmount, Ultra Magnus and the remaining Autobots were captured and were sentenced to be executed. Fortunately, Smokescreen revived Optimus with the Forge. Optimus was revived in a new body and he flew to Darkmount where he managed to save Ultra Magnus along with the other Autobots.

Optimus and Ultra Magnus greeted each other respectfully, but the former was surprised to see him on Earth. Optimus addressed him as commander and Ultra Magnus addressed him as 'Sir' who commented on his new appearance, stating it as 'Robust' and the two managed to escape from the destruction of Darkmount. When the team reconnected at Unit E, Ultra Magnus honorably relinquished his command over to Optimus, whom then happily welcomed him into Team Prime. When Ultra Magnus asked Optimus what a "Kilt" was, Optimus replied that Agent Fowler was rather oblique and personally told Ultra Magnus that he finds it best to just simply nod and mobilize. When Ultra Magnus attempted to install some discipline into Team Prime, the team did not like this way. When Optimus returned to base, the team turned their attention to him, leaving Magnus all alone in the corner. Optimus noticed his commander alone and later asked what was troubling him. Ultra Magnus noted that his command style was having a negative effect on the team. Optimus placed his left hand on Magnus' right shoulder which he told Ultra Magnus that the Elite Guard ways won't work well with Team Prime. Optimus rescued Ultra Magnus and Wheeljack from being executed by Predaking. Optimus explained the concept of "family" to Ultra Magnus. Since then, Ultra Magnus has adapted to Team Prime's family ways. In Predacons Rising, Ultra Magnus was there to see Optimus sacrifice himself to restore Cybertron. Magnus sadly watched with the other Autobots as Optimus flew into the core of Cybertron. In the end, Magnus and the rest of the team were amazed by the sparks that came from the well. Magnus is a friend/family member to Optimus.

Bulkhead met Optimus on Cybertron during the war where he left the Wreckers to join Team Prime. While they barely interact, Optimus and Bulkhead are good friends. Bulkhead was saddened when Optimus did not recognize him or the other Autobots when he lost his memories after sacrificing the Matrix of Leadership's energy to destroy Unicron's spark. Bulkhead helped the team in recovering Optimus's memories, which worked as they were able to restore Optimus to his normal self and went back to the base to celebrate. In Loose Cannons, Bulkhead explained to Wheeljack the reason he joined Optimus was that he believes that Optimus has what it takes to end the war. Bulkhead accompanied Optimus and the team usually scouting for Energon mines or other Decepticon activity. However, when Optimus kept the information of the Omega lock he questioned why Optimus didn't tell his teammates. During the battle on Cybertron for the Omega Keys, Bulkhead and the team located the Omega Lock. Though this mission was compromised when the Decepticons used the children to trade for the Omega keys. Optimus had no choice but to destroy the lock with the Star Saber, which resulted in the team splitting up from their old base until they could regroup and plan an attack. This brought up the arrival of Ultra Magnus and a strange dragon like creature the Decepticons used to hunt down the Autobots. With no sign of Optimus, Ultra Magnus informed the team that they must stop Megatron with or without Optimus. Ultra Magnus' attack on the Decepticon citadel ended in the team being captured. Soon Optimus flew in with his new jet pack and robust body, which ended in everyone escaping the destroyed citadel. In Predacons Rising, when Optimus sacrificed himself to restore life on Cybertron, Bulkhead and the other Autobots sadly watched as their leader fly in the core of Cybertron. As the sparks flew from the well, Bulkhead and the others were amazed by it. Bulkhead respects and is like a family member to Optimus.

Optimus was the only Autobot to trust Smokescreen when the young Autobot first arrived. While the others doubted his stories and believed he was a Decepticon spy, the rookie's stories of Alpha Trion convinced Optimus he was a loyal ally. He did however, think Smokescreen needed further training and needed to follow protocol more, but officially made him part of Team Prime after he defeated Starscream and secured the Apex Armor. He later claimed Smokescreen needed to further assimilate himself into human culture and the ways of Earth. He lost his patience once with him after he took Jack on the mission to get the Star Saber, though he was glad that Smokescreen had found it. During the battle for the Omega keys on Cybertron, Smokescreen wanted to give his key to Optimus, as he stated to Optimus "Optimus, an honor like this doesn't belong to me." Though their mission was complicated when Megatron used their human friends to trade for the Omega Keys. This results in Optimus destroying the Omega Lock with the Star Saber and the destruction of the Autobot base. When the Autobot base was destroyed, Smokescreen managed to hide the wounded Prime and tried to restore him. These actions convinced Optimus that if anyone should succeed him it should be Smokescreen, despite the young bot's objections. Smokescreen later healed Optimus with the Forge of Solus Prime giving him a new body. In Predacons Rising, Optimus gave him subtle signs even before his sacrifice that he remained convinced Smokescreen was the best choice for a new Prime. Smokescreen and the other Autobots sadly watched as their leader fly into the core of Cybertron. As the sparks flew from the well, Smokescreen and the others were amazed by its beauty. Optimus exhibited great trust in Smokescreen, enough to tell him he was worthy of Primehood and possibly of his earlier life. Smokescreen is like another son to Optimus, like Bumblebee.

Wheeljack met Optimus Prime on his first trip to Earth. When he returned Earth with Dreadwing, Wheeljack began to follow his own ways until Optimus warned him to follow his lead. Bulkhead talked to Wheeljack about the old days and how he gave up being a Wrecker, which Wheeljack responds "because Prime was the real deal." Bulkhead and Wheeljack made up their old Wrecker hand shake code, "Wreckers don't call for backup. They call for cleanup!!" They attack Dreadwing, but Dreadwing had already set up a trap and the Wreckers fell under it. Wheeljack was under the rubble but Bulkhead was captured. Optimus comes to Wheeljack's aid, much to Wheeljack's surprise. They went in Wheeljack's ship and ventured to rescue their friend. In his ship, Optimus seemed tightly packed inside and tried to make conversation. Optimus said "You and Bulkhead shared quite a history and yet you prefer to work alone." Wheeljack responded by saying that the Wreckers were scattered a long time ago and being alone wasn't complicated. They found Bulkhead with a time bomb strapped on his chest. Wheeljack tried to disarm the device, while Optimus sneaks away to find Dreadwing. When Bulkhead noticed Optimus was gone, Wheeljack corrected himself by saying that Optimus was the first to leave. But Bulkhead denied it and said that Optimus would never do that. Eventually after an argument, Wheeljack finally realized that Bulkhead was right about Optimus and that Dreadwing was the only able to defuse it. Dreadwing defused the bomb and blew up the dock. He escaped and left them. Back at base, Wheeljack apologized to Optimus and said it was an honor watching him work. Optimus extended his hand to welcome Wheeljack to the team, but Jackie wanted to explore Earth more, in his new vehicle mode. In Evolution, Optimus saved Wheeljack and Ultra Magnus from being killed by Predaking. In Predacons Rising, Wheeljack was impressed and stated "that's why he's Prime" at Optimus when he was able to retrieve the AllSpark from a bunch of space rocks. Wheeljack witnessed with the other Autobots as Optimus gave them a last goodbye speech and when he sacrificed himself to go into Cybertron's core to fully restore it to bring life back on their home.

Optimus saved Arcee from Airachnid in Partners. Optimus aimed his gun at Airachnid as he ran towards her to save Arcee. Airachnid pushed Arcee and escaped before Optimus could blast her. Later when Optimus was frozen by the immobilizer, Airachnid told him that he was the true prize and that she could use it as a way to getting Megatron's trust. Bumblebee punched Airachnid and the device broke in the process. Unlike other series, Airachnid is not Elita One. Optimus did not state Airachnid was Elita One nor did he have a flashback about her. Airachnid is one of Optimus' enemies and she treats him like a worthy prize.

Optimus was angered that Dreadwing had terminated Seaspray when Wheeljack explained Seaspray's fate to the Autobots. On a mission to resuce Bulkhead from Dreadwing, Optimus attempted to reason with Dreadwing by stating Megatron's principles are not right and tells Dreadwing there was another way if Dreadwing cooperated in deactivating the bomb on Bulkhead's chest, which Dreadwing had placed. Eventually after a chase and Optimus trapping Dreadwing with the dock's crane, Dreadwing deactivated the bomb on Bulkhead but activated the other ones he had set around the loading docks area before escaping. In Crossfire, Dreadwing reasoned with Optimus in letting Megatron go and allowing the Autobots to live, which Optimus ensured he had Dreadwing's word when Dreadwing had placed his gun out of sight. In Triangulation, Optimus and Dreadwing encountered each other again where they tangled in Antartica searching for a relic. Dreadwing assumed Optimus already has the relic but Optimus revealed he was going to ask Dreadwing the same question on the relic. After a lengthy fight, Optimus trapped Dreadwing under a pile of snow after shooting at a wall that was holding snow. Dreadwing recovered and soon met up with both Optimus and Starscream. Optimus fought Dreadwing outside of the relic's storing place while Starscream was left to take the relic for himself. When Dreadwing was about the making a blow on Optimus, Starscream intervened in the Apex Armor and proven to be a stronger adversary for both Optimus and Dreadwing. Eventually, Optimus made a temporarily alliance with Dreadwing in taking down Starscream, which worked as they managed to get Starscream to fall beneath the ice with Dreadwing's explosions surrounding him in a circle. Optimus did not want to continue fighting Dreadwing and offered him a chance to join the Autobots to avenge Skyquake. Dreadwing refused and promised to terminate Optimus the next time they met before flying off. In Regeneration, Optimus and the Autobots were contacted by Dreadwing who was giving them the Forge of Solus Prime. As they engaged in a conversation, Optimus puts away his blasters as he tried to offer Dreadwing another chance to join them. However, Dreadwing felt that accepting their kind would not be the same as betraying his before flying off. While Optimus may or may not beware Dreadwing was killed, Dreadwing had seen Optimus as a worthy foe despite blaming Optimus for his brother's death. Optimus even offered Dreadwing chances to join the Autobots and has shown more respect for Dreadwing than any Decepticon, since Optimus regrets being a part of Skyquake's demise. Dreadwing may have forgiven Optimus and Optimus may have forgiven Dreadwing as well, seeing how Dreadwing may be the only Decepticon who Optimus appealed to numerous of times.

Soundwave is one of Optimus' enemies. Soundwave is tricky and will not hesitate to take down Prime. Though Optimus is rarely seen to battle Soundwave head on. In Project Predacon, Optimus battled Soundwave in the sky until Laserbeak disabled Optimus' jet pack for a few moments. Soundwave managed to ground bridge the Predacon bone directly into Megatron's hand. In Minus One, Optimus was able to knock out Laserbeak and shoot down Soundwave with ease. The Autobots brought back Soundwave to their base while Laserbeak retreats. During the interrogation, Optimus asked Soundwave about Megatron's plans. Soundwave did not give any information but he did annoy Optimus by uploading a smile on his screen face and playing a remix of Optimus' voice. When Ratchet suggested that they open Soundwave up after he played a loud sound that hurt their ears, Soundwave told them "Soundwave superior. Autobots inferior." before crashing his own drives.

Starscream is one of Optimus' enemies. Starscream has his ways of making Optimus angry. He would even go to extremes just to get rid of Optimus. In Out of His Head, Starscream angrily mocked on how Megatron's greatest mistake was allowing Optimus to live. Starscream also came close in shooting Optimus with his missile until Megatron actually flew in and saved Optimus. In Shadowzone, Optimus shot Starscream's right arm off, which left him vulnerable. In Partners, when Starscream wanted to be an Autobot, Optimus had doubts in trusting him. Optimus agreed with Arcee about making Starscream an ally. However, when Starscream beaten up Arcee, Optimus did not take Starscream in. In Orion Pax, Part 2, Starscream was shocked to see Optimus on the Nemesis. He was about to aim his missiles at Optimus but Optimus didn't recognize him. Starscream found out that Optimus lost his senses and did not know who he was. He was close to using this as his advantage until three vehicons came in and made Starscream escape the ship. In Triangulation, when Starscream was walking with Optimus through Antartica, he did not believe that Optimus would take their alliance for granted even with Starscream helping in restoring Optimus' memories in Orion Pax, Part 2 and saving Arcee's life in Crossfire. Optimus points that Starscream did these things for his own interests. Starscream that nobody can be selfless as Optimus is. In Inside Job, Optimus raged out when Starscream stoled the omega keys from the Autobot base. In Darkest Hour, Starscream grew mad about Optimus destroying the Rebellion. In Synthesis, Optimus engages a dogfight with Starscream and several vehicons in the sky. Starscream managed to destroy Chip, which angered Optimus to attack Starscream but he managed to escape back to the Warship via Groundbridge. Though they are bitter enemies, Starscream sees Optimus as a worthy opponent and would even spare his life at times.

Optimus first became aware of the Predacon following the events of "Project Predacon." He eventually met Predaking in person finding him ready to kill his field commander and expert wrecker. He saved them from Predaking and fled from the furious clone's wrath. He eventually fought him again in the Arctic. When Predaking was temporarily subdued, Optimus ordered him to stand down and Predaking responded by stating he would never bow to him and knocked him out with a kick. Following the events of the film, Predaking may have forgiven Optimus.

Optimus and Knock Out were seen to fight each other in some occasions. In Speed Metal, Optimus brutally breaks a piece of Knock Out's door to rescue Vince from Knock Out. However, in the ending of Predacons Rising, when Knock Out became a member of the Autobots, he revealed he looked up to Optimus as role model. He looked gloomy when he saw Optimus fly into the Well of AllSparks but was amazed by the sparks that came from it.

Orion Pax was a simple worker in the archives of the city of Iacon. His job was to listen to messages from the information network to categorize them. The Cybertronian did his job without hesitation until he heard the messages of Kaon's arena champion, Megatronus. The gladiator's statements made the young archivist think about the injustice of the class system and the corruption of the authorities. Orion began communicating with Megatronus, who became his friend and mentor. When they managed to gain an audience with the high council, Megatronus proposed his concept of a just society, but then exposed himself, demanding the violent overthrow of the old order and wanting to become the next Prime. Pax, however, disagreed with the use of violence to achieve order and justice, and his words resonated with the council members. Megatronus, frustrated, decided to wage war against all who did not share his views, and swore an oath to gain the leadership matrix wherever it was found. Pax eventually became Optimus Prime, obtaining the matrix from Primus and sending an ancient Cybertron artifact to a remote sector called Theta Scorpion to keep it safe from Megatron. During the war, Optimus Prime organized an ambush for the Decepticons attacking an energy factory in Iacon. When confronted by Megatron, Optimus decided not to destroy him after seeing his loyalty to his fighters. This displeased some of the Autobots, and Optimus found himself facing a tribunal. He then made the decision not to advance on enemy positions due to lack of power for the ship. Optimus had to lead a rescue mission, during which he defeated Megatron and stripped him of his Dark Spark with Orion Pax worked in the archives of the city of Iacon and worked on classifying messages received from the information network. One day, he heard remarks from the gladiator Megatronus that made him think about the unfairness of the class system and corruption. Orion began to communicate with Megatronus, and they became friends. When they approached the High Council, Megatronus proposed his concept of a just society, but then revealed his true intentions of violently overthrowing the old system. Orion disagreed with him and later became Optimus Prime. Megatron, in order to gain the leadership matrix, started a war against all who were against his ideas. Optimus set up an ambush for the Decepticons, and during the battle failed to destroy Megatron, who later proved to be his nemesis. When the Decepticons attacked the energy factory, Optimus was able to repel their attack thanks to the bravery and strength of his warriors. Ultimately, Optimus decided to launch Operation Longshot, which ended with him defeating Megatron and saving Cybertron.

As the war drew to a close, Optimus assembled a small group of Autobots, Team Prime. When Cybertron became uninhabitable, he arrived on Earth with them and sent an encrypted message to all the Autobots, inviting them to join him in the fight against the Decepticons. In response to this call, Arcee and Cliffjumper arrived on the planet. After a long period of inactivity from the Decepticons, Optimus and the rest of the team began searching for sources of energon, the fuel needed to power the Transformers. During one such expedition, Cliffjumper was attacked by the Vechicons in large numbers. He engaged them without reinforcements, but was defeated and captured on their warship Nemesis, where he died at the hands of Starscream. Optimus, upon learning of the danger Cliffjumper was in, summoned the rest of the team and ordered them to rush to their aid. But by the time they arrived at the scene of the battle, it was too late: Cliffjumper's life signal was gone. After gathering the surviving comrades, Optimus warned them to be careful that no one would suffer the fate of a fallen comrade, and returned to base. When Arcee and Bumblebee encountered Jack, Rafe, and Miko in Jasper, Prime decided that the children were worth bringing back to the base and protecting. He later shared with them his experience fighting Megatron on Cybertron, who became his enemy afterward. Also learning of the signal from Cliffjumper, Prime led a squad to the Decepticon mine to investigate the situation and rescue his comrade. He fought, but was forced to retreat when Starscream dropped an energon bomb. Optimus saved Ratchet from a mechanism brought to life by the dark energon. After returning to base, Optimus and Ratchet decided to explore the ancient Transformers graveyard on Earth in search of the dark energon. During a battle with the reanimated Terrorkons, Optimus almost defeated Megatron, but failed. After returning to the base for repairs, Optimus learned of Agent Fowler's kidnapping by the Decepticons and warned the children to be careful. While vacationing in the Valley of Fire, Optimus shared a story with the children about Megatron's bravery on Cybertron, whom he spared. Prime regretted his decision, but promised that next time his hand would not waver.

In the run-up to the upcoming Christmas, an irate Agent Fowler showed up at the Autobot base with information about Megatron and Starscream's attack on the Russian icebreaker Yamal. Optimus ordered him to stay and promised that the Autobots would deal with the intruders. Along with Bumblebee and Ratchet, he moved to the icebreaker, where the fight began. After learning that Megatron had booby-trapped the ship, Prime realized that without Starscream's spear, he would not be able to surrender it to his enemies. Bumblebee handed the spear to the leader, who managed to fend off Megatron's attack and send it into the sea. After the ship was brought to safety, Optimus and his comrades returned to the base. When the Autobot base suddenly had an Earth Bridge, Optimus quickly arrived on the scene. The battle had begun, but there were too many enemies. Prime competently managed the battle, protecting his comrades-in-arms. Rafe was able to reprogram the bridge, and Optimus made sure everyone stayed alive. After the gas explosions at Jasper's schools, Optimus agreed with Jack that there was something suspicious about the incident. He assumed that the Decepticons were behind the attacks and recommended that they not take any chances. Later, after learning that the enemy attack had affected all the schools in the area, Prime suggested not to throw himself into the Silas venture. Upon receiving the black box from the presidential plane, Optimus realized that Starscream was the kidnapper. Following the record, the Autobots came to a large canyon where a battle unfolded. Optimus, with hopes that his plan would succeed, destroyed the enemy's base. Searching for energon, Optimus entered a scrap metal recycling plant where he was exposed to a neural refractor. Prime's consciousness shifted into a human body, and he found himself in a predicament. Together with the human, they worked together to save themselves, and Optimus found himself back where he belonged.

While searching for Miko Nakadai, who had been kidnapped by an M.E.C.H. agent named Novo, Optimus Prime, along with Bumblebee, Arcee, and Bulkhead, arrived at the location. There, he noticed that the girl was near an unfamiliar robot. Miko told him that the robot was Novo, who had been exposed to the Neural Refractor, and that he had saved her from Silas and his men. Optimus offered to help Novo, but he flatly refused and threatened to blow up the refractor. With his decision made, Optimus summoned the Earth Bridge and the Autobots, along with Miko, returned to the base. Energon's reception was interrupted by the sudden appearance of terrorists who attacked a high-tech oil extraction platform. Optimus Prime gathered his team and set out to rescue without hesitation. Encountering hostile fighters in armored exosuits proved to be a real challenge for him. Attempts to convince General Madison of a mistake were in vain when he ordered them to open fire without warning. Asked Ratchet Optimus contacted the base to think of something to avoid unnecessary casualties, as he guessed that the attackers considered their opponents to be human as well. Then, on Jack's advice, Optimus announced to Madison that he was surrendering, and as the general approached, he opened his chest module to convince him that no one was inside. Thus the incident was settled. When the signal from Bulkhead, who was on a mission in Alaska, disappeared from the monitor, Optimus Prime tried to calm Ratchet down, reassuring him that there was no cause for alarm. After a while, Miko managed to establish contact with Bulkhead via cell phone, and the medic's fears were justified: it turned out that the giant was in captivity, and his life was in danger. Upon receiving this information, the Autobots urgently assembled a rescue team and asked Ratchet to teleport them to the Decepticon ship via Earth Bridge. Contrary to habit, Optimus decided to take Jack, Miko, and Rafe with him, as the Nemesis' security system was unable to detect them. The boys soon located and freed Bulkhead, and Optimus followed them, destroying two Vehicons along the way. As the rescuers left Nemesis through a hole in the ship, Prime thanked everyone involved in the mission after returning to base. Optimus, accompanied by Bulkhead and Arcee, went to negotiate with Knockout and Breakdown, who had captured the viewers and the TV show host. Realizing he risked being trapped, the Autobot leader left Arcee outside and entered the building with Bulkhead. Optimus hoped for a stealthy entry, but Knockout was already ready for their arrival. The Autobots were forced to overcome an obstacle course to rescue a container with humans trapped in it, threatened by the Decepticon. Accepting his terms, Prime and Bulkhead helped each other and traversed the pool. They then found themselves in front of a makeshift fortress, where they were attacked by Vechicons dressed up as mummies and a monument. Wasting no time, Optimus asked Bulkhead to defend the position while he himself made his way into the fortress. Soon he reached the container with the prisoners and freed them. As the great battle came to an end, Optimus Prime felt joy not only at the victory of justice and the rescue of the hostages, but also at the fact that the truth had remained hidden from the humans. After the encounter with the Vehikons, the commander contacted Rafe on duty and asked him to open an Earth portal for the Autobots' return. However, due to an unexpected malfunction, the bridge transported the crew members around the world. Optimus found himself in the slumbering Amazon jungle, where he suddenly came across a Vehikon stranded in a swamp. The helpless soldier was rescued by an Autobot, who broke a branch and helped him get to dry land. At this time, Prime was the victim of a surprise attack from Eirachnida, who attempted to tie him with a web to a tree. But Vehikon intervened and pushed Spidey away, causing her to become enraged. Eirachnida attacked the soldier who interfered with her, but then Optimus ripped the web and hurled the Decepticoness into the swamp in one powerful blow. After Prime heard Starscream's announcement on television, he immediately realized that the invading Decepticons were trying to cause panic among the planet's inhabitants. He immediately ordered Ratchet to open an Earth Bridge portal to beam his team to the global communications satellite, Comsat-1. After instantly teleporting to the satellite, Prime and his team clashed with the Vehicons guarding Soundwave, who was controlling the signal relay. Finally, they found themselves at the base, where they were greeted cheerfully by the entire team, and it was only then that Prime realized he was facing a new phase of the fight against the Decepticons. The entire Optimus team gathered at headquarters to hear some unpleasant news: the discovered energon deposit in Kansas was already being used by someone else. To investigate on the spot, Prime and the Autobots immediately traveled to Kansas via Earth Bridge. There, they discovered that Knockout had built a time-travel portal with the help of the Vehicons and Breakdown. Upon seeing the Decepticons, Optimus gave the team the order to go on the attack, and Bumblebee attempted to disable the device. However, he was too late, the Decepticon scientist had already triggered the portal. Optimus Prime traveled to an abandoned nuclear power plant after receiving a message about Megatron. Upon arrival, everyone present, including the Decepticons and Autobots, found themselves in a strange place that Prime identified as a parallel dimension. Ratchet, who had remained at the base, was able to trigger a reverse loop thanks to Rafe's assistance, causing Optimus and his comrades to return to the real world. Optimus then thanked Ratchet and another genius for their help, without which they might have been stuck in another dimension. Upon arriving at the power plant, Prime immediately noticed that the energy readings were on point, despite his first impression of abandonment. Stepping inside, he found a space bridge portal powered by the energy of the nuclear reactor. There was no one in the room, and suddenly a powerful impact knocked Optimus off his feet. Megatron attacked the Autobot leader, and a fierce battle ensued. In the end, Prime prevailed and killed the Decepticon leader. Optimus was surprised: he didn't expect the victory to be so easy. Several Megatrons came out of the space bridge, and Optimus Prime gave them a good showdown, but got hurt in the process. He needed medical attention, but he couldn't leave without figuring out what was wrong. Inside the portal, he saw the real Megatron and realized that the malfunctioning space bridge was creating Decepticon clones. He then decided to trick the false Megatron by pretending to mistake him for the real one to find out which one was the imposter seeking to take his place. After Optimus Prime offered Megatron's cooperation, the clone agreed and together they cut the cable that powered the bridge. This allowed the real Megatron to break free and engage in battle with his doppelganger, who was eager to destroy the “genuine” one. During the robot battle, Optimus Prime returned to the Autobot base, happy that his plan had worked.

One day, the Autobots' territory received a distress call from a spaceship that had crashed. Optimus Prime and Ratchet immediately went to the scene. Prime looked inside the ship through the breach to make sure no one was left alive after the disaster. Suddenly, a hideous creature jumped out of the breach and attacked him. Ratchet carried the injured Prime back to the base without noticing the parasite. Prime was on Cybertron at the time, where he congratulated the Autobots on ending their long war with the Decepticons. He was overjoyed, but unaware of the parasite in his brain. Suddenly everything disappeared and he found himself in Ratchet's repair shop. He was shocked to see the parasite on Ratchet's head. Miko explained that the doctor had saved Prime and now needed to save him. Prime was afraid to perform the surgery, having no medical knowledge. However, the parasite burst and Ratchet was saved. Prime was overjoyed that his friend was okay. When Bulkhead told Prime about the unusual artifact seen on the TV show, the Autobot commander realized it was a dangerous device. He forbade Miko to look closer at it, but the girl didn't listen. She traveled with her friends to the site of their find, which led to a confrontation with M.E.C.H. and other agents. After the adventure, Prime reminded Miko of his warning. Prime was concerned about Wildjack's disappearance and sent other Autobots to search for him. They later returned with Wheeljack and recounted the release of the destroyer. Optimus recognized that humans and Autobots had once again proven their cohesion. Megatron used the leadership matrix to trick Prime into working for the Decepticons. He convinced Orion Pax to search for artifacts on Earth. After regaining his memory, Optimus began searching for the relics to keep them out of the hands of the Decepticons.

While traveling to Antarctica to retrieve a new artifact, Optimus Prime encountered the Vechicons and Dreadwing, who were escorting the captured Starscream. Prime engaged the Decepticons in combat: first destroying the Vechicons, and then, by shooting an ice block, he was able to trigger an avalanche on Dreadwing. Together with the captured Starscream, he headed towards an Antarctic base belonging to the humans. Calling Agent Fowler, the Autobot leader organized the evacuation of the staff, after which the complex emptied. While searching for an artifact, Dreadwing attacked Optimus, but Starscream found the super armor, retrieved it, and attacked both Transformers. To defeat their enemy, they detonated mines on the ice, forcing Dreadwing to leave and convincing him not to continue the fight since the super armor was already lost. The Decepticon left and the Autobot leader returned to base. Optimus Prime and his companions were discussing the situation with Starscream at the base when a message arrived from Dreadwing wanting a meeting. Upon arriving, the Autobots prepared for battle, but the Decepticon turned out not to fight, but to hand over Solus Prime's hammer. He explained that he no longer wished to do business with the Decepticons due to their treachery. Having irrevocably lost hope of rebuilding Cybertron, he handed over the four omega keys in Lorde's possession to Optimus. Optimus invited the Decepticon to join the Autobots, but he refused and flew away. Using his hammer, Optimus turned the Earth bridge into a space bridge and then traveled with the team to Cybertron. There, the Autobots managed to defeat Megatron's army and retrieve the Omega Keys. The Decepticons captured the humans and demanded surrender, but Optimus and his team agreed to an exchange, giving up the keys in exchange for friends. An attempt by the Decepticons to transform Earth using the Cyberform was thwarted by Optimus, who destroyed the device. The leader of the Autobots went to Earth and repelled the Decepticons before returning to base. Upon arriving at the base, the Autobots found that Megatron had completed the first stage of the cyber-formation and began shelling their hideout. Leaving the base, the Autobots teleported to different locations on the planet to confuse the Decepticons. Optimus, being the last one left, destroyed the bridge control panel and was destroyed by the Decepticons. A short time later, Optimus was pulled from the wreckage and learned of what had happened.

When the Decepticon activity had diminished, Optimus, who had been conducting the research, returned to base. He expressed his suspicions that they may have prepared all the necessary ingredients to clone an entire squad of Decepticons for the rest of the team. Seeing that Ultra Magnus was worried about something, Prime began a conversation with him. He shared with the Autobot leader his worries about his management style, believing that it was negatively affecting the group's mission definition. Optimus noted that during his time on Earth, all of the team members had bonded to the point where they were no longer just an army. The discussion was interrupted by Ratchet informing them that the base's scanners had detected energon. Given the critically low stored energy, the team set out in full force to capture it. After defeating the Vehikon squad that was transporting the energon, the Autobots captured it and returned it to the base. Smowkscreen and the Destroyers headed to the cave to see if there was any more fuel. They soon returned with Bulkhead, but Wheeljack and Ultra Magnus were not with them. In addition, an explosion erupted from the mine, forcing Optimus to go in search of his missing comrades. He managed to find them just in time: the Preaker, who had defeated Wheeljack and Ultra Magnus, intended to destroy the Autobots. But Prime managed to prevent it: he fired his machine gun at the beast, then gathered his subordinates and left with them to the base. There, Ratchet set about repairing Magnus' damaged arm. The latter, having continued his conversation with Smoksrin, asked the Autobot leader what Equality was not an army. Prime replied that it was family.

After the Decepticon activity diminished, Optimus returned to the base and expressed suspicion that they had gathered the necessary components to clone the Legion of Pre-Cons. While discussing his command style with Ultra Magnus, he noticed that everyone on the team had become like family. Soon the team went after the energon, defeating the vehikons and bringing it back to base. Optimus and his companions went in search of Wheeljack and Ultra Magnus, who were attacked by Predaking. He managed to thwart the attack and returned to the base, where Ratchet began fixing Magnus. Optimus claimed that the team was a family. Megatron wanted to reconstruct Omega Castle to revitalize his home planet and cyberform Earth. To do this, he ordered the Decepticons to gather components from Cybertron, use cybermatter, and steal technology from humans. Eventually, the Decepticons were able to steal a particle gas pedal, but were attacked by the Autobots. Predaking attacked the Autobots during their mission in Antarctica. Optimus fought him while the others continued the mission. Eventually, Predaking was able to strike at Optimus, but Megatron intervened and prevented the attack. Eventually, the pre-Raking surrendered and helped Shockwave steal the particle gas pedal. The Autobots forged the hangar's license plate number to avoid destroying it. This helped them avoid Starscream's attack on the other hangar.

Optimus approached the wrecked ship, where he was met by Arcee and Bulkhead, who helped Wheeljack out of the wreckage. Wheeljack asked Prime about saving Spark, and he answered in the affirmative. Holding the ark, Optimus continued flying, but Unicron struck him, damaging his jetpack. Unicron then took the reliquary from Optimus, but did not find Spark inside. Trapped, Unicron was expelled from Megatron's body by the ark. Optimus noted that the Prime artifact had weakened Unicron's dark essence. Smokescreen wanted to ask a question about Spark's whereabouts, but they were interrupted by Starscream, happy to discover that his lord had returned. Seeker supported Megatron, informing him that the Decepticons would rise again and could take over Cybertron. However, Megatron refused the war, realizing the true nature of tyranny, and flew away in alt-form. To defeat Unicron, Optimus had to release the great Spark to capture the spirit of chaos. The Spark was placed in the Matrix of Leadership and merged with it, it was necessary to sacrifice the Matrix to the planet's core. Optimus decided to make the sacrifice, convincing the Autobots of the necessity of this decision. In his final speech, he urged them not to mourn his death, but to continue to fight for peace. Bumblebee promised to follow his instructions. Optimus smiled sadly and disappeared into the core, revealing his chest. New Sparks burst from the core, giving birth to new lives, among them was a Spark with a blue-red aura, heralding Optimus' eventual return to life.
