Bio[]

Cooper Black is the son of Sans and a female skeleton only ever refered to as Bell. Apparently, shortly after Cooper's birth, Bell died. Cooper is a cheerful young skeleton and a novice with Puns. He is also suprisingly smart for someone his age. Ever since the accident his father doesn't let him...do anything other than watch TV, which is how he's become obsessed with certain Anime (One Punch Man, My Hero Academia, ETC,)

Appearance[]

Cooper wears a black turtleneck and grey jeans. Sadly, a accident from early on left Cooper without any leg below his knees and confined to a wheelchair, something he gets a lot of grief about from Mettaton.

Relationships[]

Sans[]

Ever since the "accident" Sans has been a bit...protective of his son. While this annoys Cooper to pieces, he still has a fairly healthy relationship with his dad.

Toriel[]

Toriel and Sans got married when Cooper was seven. Cooper has a fairly good relationship with his stepmother.

Frisk[]

Frisk is essentially the older sister Cooper never had and he is more than happy that they are step siblings. Jury's still out on what Frisk thinks.

Papyrus[]

Cooper loves his "Uncle Paps". In fact one of his favorite pastimes is to annoy Papyrus to death with his novice puns.

Impact[]

Impact often treats Cooper as his Sans, something that Cooper is perfectly okay with.

Abilities[]

I assume you know what a Gaster Blaster is.

Novice Pun[]

More a Physcological warfare than a actual attack, Cooper will annoy his opponents with terrible, and in most case repetitive, Puns.

Bone Attacks:Vary in Size and Technique[]
