Sans (Unbreakable)

"Tori... i'm sorry. i-i'll fix it. i promise..."

- Sans after witnessing Toriel in a corrupted state

Sans is the main protagonist of the Undertale comic, Unbreakable made by TheJessofMess. He is a lazy skeleton, the older brother of Papyrus, the Royal Judge of the Underground and is Frisk's archenemy.

Appearance
Similar to his appearance in Undertale, Sans is a short skeleton monster that wears a blue jacket and black gym shorts with a white stripe on each leg. However, the hood of his jacket now has grey fur and instead of wearing a white t-shirt underneath his jacket, he wears a turtle neck shirt.

After his fight with Frisk in Snowdin, he has a small crack on the right side of his head that continues to grow bigger due to him picking at it.

Personality
It can be assumed that Sans originally behaved the same to how he did in the original Undertale; That being said, lazy, comedic and observant. However, after Frisk succeeded in a Genocide Run and is now doing a Pacifist Run for their own enjoyment, Sans begins to suffer from flashbacks from the last timeline because he still retains those memories. This causes him to act odd and for other monsters to think he's becoming crazy. The only one who wishes to help him is his brother, Papyrus. While Sans is touched by this, he is afraid Papyrus either wouldn't believe him or if he does, he doesn't want him to suffer what he is going through.

Sans maintains his fake personality as he does in the game, but his sanity unraveling causes him to break character. He still retains his intelligence and judging abilities, and he gets confused whenever he can't judge someone who doesn't have any sins or EXP (Frisk).

Despite his apathetic views towards life, Sans does genuinely care about those he holds dear. Such as Papyrus, as he is afraid of others hurting him or taking advantage of his innocent personality. He again shows this side of him when he realizes Frisk did something to Toriel that can be considered brainwashing and, despite having suffered through so much, he promises to find a way to help her before retreating.
