Optimus Prime and Megatron

Intelligent, ruthless, and goal-oriented. A highly experienced and powerful warrior, he's one of the most powerful Transformers ever. He evaluates his associates primarily in terms of the value they can bring to the Decepticon cause. He hates traitors, but the "public interest" is far more important to him than personal feelings.

Appearance
Before the first death
99
Megatron originally had a black and gray body and wore the Decepticon insignia on his lower chest. Immediately above it, as well as on his shoulders and arms, were red plates that provided additional armor. A rather long, black-painted cannon was mounted on Megatron's right arm, and his head was protected by a helmet. All illuminated elements of his body (except for the red eyepieces) were painted light purple.

After the first revival
590436558
After Megatron was crushed by Metroplex and then reassembled and revived by Soundwave, his armor became thicker, all the black parts of his body were removed (even his cannon was replaced with a gray one), and the red parts remained only on his forearms and small areas on the backs of his legs. The glowing spots became more numerous.

After returning from space travel
98
When Megatron returned to Earth to once again lead the Decepticons, he appeared before his subordinates with a new appearance: he wore gray armor with numerous pointed and rounded elements, almost completely enveloping his body. The cannon on his right arm became purple, as did the backs of his shins. The Decepticon emblem moved from the lower part of his body to the upper part.

Personality
For many of his subordinates, Optimus Prime is a mythical figure, a force capable of turning the tide of battle with his mere presence and routing Decepticon forces. But the truth is, Optimus is not only strong but also wise, ready to dispense wise counsel as often as he strikes. This doesn't mean he relishes the thrill of battle—quite the opposite, in fact. In an ideal world, Optimus and Megatron could settle their dispute peacefully, avoiding further destruction on Cybertron and the galaxy, but alas, Optimus's adversaries often leave him no choice. Nevertheless, in the heat of battle, Optimus always shows the utmost respect for his opponents. Optimus never seeks conflict, but rarely refuses to fight for what's right and defend his beliefs, even when the odds are slim.
Millennia of war have shaped Optimus into a serious, even stern leader who prefers action over talk. Although he often hides his emotions, Optimus cares deeply for the well-being of his Autobots and humans, and to some extent even for the lives of his Decepticon enemies—for Optimus, all lives are sacred. Unlike his nemesis Megatron, Optimus views humans and other races as equals to Cybertronians, which ultimately led him to destroy the Omega Lock when the Decepticon commander attempted to use it to transform Earth into Cybertron.
Optimus, surprisingly, is also quite diligent in his studies, considering he was once Orion Pax's archivist. Before receiving the Matrix of Leadership, Orion was a humble working-class bot in the service of Alpha Trion. Timid and taciturn, yet endlessly courageous, Orion was a bright-eyed dreamer who envisioned a better future for Cybertron. Despite his many strengths, Orion's naivety was perhaps his greatest weakness, easily exploited.

Appearance
Optimus Prime is a large Cybertronian with an athletic, muscular build. His body color scheme combines predominantly red and blue with accents of gray and black. His helmet, with ear-like "antennas," is equipped with a built-in radio behind the "ear" and a visor that, like a knight's, covers the lower half of Prime's face in battle. His eyes glow a light blue, close to blue, and his small pupils are also equipped with a depth-of-focus system. The dual Autobot logo on his shoulder pads serves as a tracking device, allowing both allies and enemies to locate him.
After his restoration at the beginning of Season 3, Optimus's appearance became identical to that of the alternate version of the character from Michael Bay's MCU. His body segmentation and some of his complexion changed, with the red and blue colors spreading evenly across his body. He also gained a jetpack with double wings.

Armament

The blade is a long, pointed blade with blue LEDs.
The Double-Barreled Cannon is a firearm that fires blue plasma. Its shots deal significant damage and are capable of killing small to medium-sized Decepticons.
Both weapons are organic, retractable parts of Optimus's body - he simply transforms his hands into weapons, like many others of his race.

Optimus Prime is the titular protagonist of Transformers: Prime and the titular protagonist of Transformers: Robots in Disguise.
Over the centuries, loss and war have made Optimus seem stern and serious to most. But look closer, and you'll see a man who genuinely cares for his fellow humans, displaying a warmth and kindness that his closest friends can rely on. You'll also see regret that his comrade has fallen victim to the darkness, and a faint glimmer of hope that he can be saved.
