Seraphim!Sans

Sans frequently works on the machine behind his house. The machine is supposed to free Gaster from the Void. However, he needs knowledge about Quantum Physics. Knowledge he does not have. Sans used to love setting up puzzles and traps, just like his mother. Now every time he sets it up, it reminds him of the mother he lost. While Sans didn't inherit Gaster's Battle Eye, he got it through the explosion that caused Gaster to get voided. Sans's really low stats prior to the 7 Human Souls was due to a disease he inherited from his mother.

Deep love for his family. He'd only do a serious battle if his loved ones were in serious danger or they were killed by someone

Undertale!WD Gaster - Sans believes he is an overprotective father however he understands why, since his father told him what happened to his mum and about the condition Sans has. Undertale!Lucida Gaster - The death of his mother definitely took a toll on him. Being the best and only mother he would ever have and want, he wishes she was still alive. Undertale!Papyrus - Sans deeply loves and admires Papyrus. He loves to joke around with him. Although this is true Sans still deeply cares for him and worries a lot about others harming Papyrus. Undertale!Astro - Having raised Astro, he cares for Astro deeply. He sees Astro as a brother and a friend and he's happy that Astro is there for his father where Sans cannot. Undertale!Alphys - Sans sees Alphys as a pretty intelligent friend and someone who can be trusted to work with complicated sciences since his father trusted her with them. Undertale!Asgore Dreemurr - Sans knows Asgore pretty well, and talks to him on a frequent basis. Sans wishes Asgore and Toriel spoke more, though. Undertale!Toriel Dreemurr - Both Sans and Toriel love sharing bad jokes and joking around. Other than that, they never met in person. Sans believes that his father knows the person behind the door however, it was never confirmed. Undertale!Grillby - Sans's relationship with Grillby is a bit wonky. Grillby is a friend of the Gaster Family and Sans constantly goes to Grillbys for either a bottle of ketchup or the worst burger on the menu for reasons that Grillby is unclear of. Sans knows the sheer amount of money he owes Grillby, as per the tab, however there are 2 reasons why Sans has yet to pay the tab. 1, he does not have the funds. 2, he cannot be bothered. Error404 - The one person Sans admittedly should not have confided in, Sans now tries his best to get out of his grip, however he can't seem to get to him to even begin talking to him.

[Toy Knife] This attack utilizes little plastic knives that only show up at the most opportune moment in the fight. [Jawless Gaster Blaster] This is not an ability since neither Sans nor Chara can control it. The Gaster blaster will block Seraphim Sans' way, making the Opponent hit it instead. Alternatively, it may also fire a beam immediately. Frisk controls it. [Soul Blasters] Gaster Blasters that appear with a Rainbow Soul hovering in front of the jaw, this Gaster Blaster is an immensely powerful variant of the Gaster Blasters which Sans can summon at any size. [Enhanced Blue Soul Ability] Augment or Negate anyone's soul gravity at will while also crushing bits of their soul, dealing damage. [Eye of the Souls] Sans's yellow eyes, these eyes allow him to see things seconds before it happens. This is what allows him to dodge the way he's able to. This Eye is what allows his damage to ignore invincibility frames, why he knows about SAVE, LOAD and RESETS and he's able to see other timelines. This ability also doubles his stamina count. However, he can only maintain this amount of stamina as long as his Seer's Eye is activated. It also enables his attacks to deal the same amount of damage every 50 milliseconds with contributes to his power. [The Soul's Retribution] A variation of the KR ability now enhanced by the 7 human souls is a poison effect that activates when the user decides. This ability multiplies the damage of an attack by 125% as Poison damage, adding it onto the currently delt damage. [Bone Manipulation] Can summon bones with the power and durability of the 7 human souls to do as he desires. He is also able to use blue bones.

[Teleportation] The ability to teleport from one place to another. [Soul Weapons] Sans has the ability to create transparent weapons and tools out of the powers of the 7 Human Traits. When he uses the tools of the souls, the tools take on a color depending on which soul used them. This includes Determination Melee Weapons, Justice Ranged Weapons, Bravery Combat Weapons, Patience Constriction Weapons, Perseverance Poison Weapons and Integrity Attack Enhancing Weapons, all combined into the weapons and tools created. [Relentless Killer] As his determination to kill increases, so does his damage. [SAVE, LOAD and RESET] The ability to save a point in time, the ability to go back to that point in time, and the ability to reset the timeline to the beginning. This is essentially makes Seraphim!Sans unkillable by normal means. [Frying pan] This is his first tool during the fight with Gaster. He uses this tool to Block or protect himself from Gaster's first attack. [The Prototype Gaster Blaster] When KINDNESS is with him, he can use this ability. [Gun] This is another ability. He uses this ability to shoot during the Fight, the shape of the gun is like Empty Gun in Undertale. However, the difference between that is that it has bullets. When JUSTICE is with him, he can use this ability. [Ballet Shoes] This is another Ability, The ballet shoes function the same during Omega!Flowey's fight, They go up and down when INTEGRITY is with him, he can use this ability. [Tough Glove] This is another ability, the Gloves function, hitting the Opponent several times. Punching more times will result in dealing more damage. When BRAVERY is with him, he can use this ability. [Notebook] The “attack” is more similar to what the item does in the game, which is that it increases your evasion while having really poor attack stats.

ATK - 999 DEF-999 HP - 99,999 Stamina - 101,997

Despite all that has happened to Seraphim!Sans, his personality is almost the same as Undertale!Sans, being laid back and flippant, often sleeping on the job and taking breaks. His laziness is a combination of fatalism and apathy, as he is aware of timeline resets. Although Sans does possess traits of Determination, Justice, Perseverance, Patience, Integrity, Bravery and Kindness. He enjoys being mischievous. Sans primarily acts this way towards those he is on good terms with. His antics range from an assortment of illogical, juvenile, and slightly inconvenient pranks. Examples include Sans "selling fried snow," using whoopee cushions, sharing an unscrewed ketchup bottle, and eye paint on a telescope. He is not above utilising his teleporting or other magic for practical jokes, either. Sans is also fond of making the occasional low-brow puns. He enjoys making others laugh in general, as he also performs at the MTT Resort as a comedian. Despite Sans being apathetic towards his own life, he is considerate to those he cares for. For example, Sans is a regular at Grillby's, and the monsters and Royal Guard dogs treat him kindly. Sans has informed Big Mouth about "all kinds of incredible foods," yet Big Mouth comments that "he always orders the worst burger off the menu." Although Sans hates making promises, he respects Toriel's request to watch out for any humans. Even if the human killed people that were close to him, Sans refrains from broaching the topic until the Judgment Hall. In a Neutral Route ending where Papyrus or Toriel is alive, Sans omits the human slaughter to either of them. He is also observant; Sans reads the human's expressions and can often tell when they have already done certain tasks. Though Sans is usually agreeable, he can become eerily serious to emphasize a subject. Regardless of the human being partially or wholly merciful, Sans tells them that if "the old lady" had not made him promise to protect them, "(they'd) be dead where

Seraphim!Sans is a very powerful entity, named a God in his Timeline for his small list of weaknesses and immense power. Seraphim!Sans is essentially Sans with the power of 7 Human Souls. Despite this, sometimes his laziness will get the better of him as he just does nothing.

Backstory After a Genocide Route, Sans becomes fearful that Frisk would not come back (and reset the world back to normal) after a Genocide Route. In a state of panic, Sans kills Frisk and takes their SOUL at the beginning of the timeline, and when Asgore refuses to fuse with the other six to free them, he does so himself, believing that this is the best for all monster-kind. He then breaks the barrier. Meanwhile, Papyrus discovers Frisk's corpse. Not knowing how human death works, he takes the corpse to Undyne, who goes along with it to not upset him. They both go to ask Alphys about where the SOUL and Sans went, and they rush over to the castle. There, Undyne tries to assault a hulking beast, who turns out to be Sans in his new form. Toriel then arrives. Furious at Frisk's death and believing its Asgore's fault, she launches an enraged and heartbroken assault. From her conversations with Sans, Toriel recalls Papyrus' name and a fish with the ability to do so hinders her ineffective attacks. After everyone is done calming down, Asgore eventually decides that he will not inform the rest of the Underground about the now-broken Barrier until further notice, and Alphys takes the initiative to make plans to extract the SOULs from Sans. When Sans and Papyrus return to Snowdin, nobody recognizes Sans, whom Papyrus calls his 'cousin'. Later that night, Sans can't sleep because of the SOULs talking inside of him, and he goes outside only to fall asleep later. Then, in the morning, as he wakes up he finds Monster Kid and some others asking to touch his tail. He accepts, then Papyrus comes out telling him they have to go. Unfortunately, 404 appeared one day and assaulted Seraphim before noting to him of something that was happening or going to happen and that he needed Seraphim for it. Seraphim reluctantly agreed. However, he did not know what he was signing up for.
