Killer!Sans uses a sharp knife as his primary weapon, similar to a kitchen knife but with slightly different proportions. He has the ability to teleport, which he can use to dodge attacks or quickly escape from combat. Additionally, Killer!Sans can summon sharp-edged bones, which can be used as melee weapons if necessary. He also uses Gaster Blasters, which can fire laser beams like regular blasters but with the added ability to bite. Like other Sanses, he can use telekinesis to hurl opponents.

Nickname: Killer Connections: Nightmare!Sans (Master) Universe: Alternate Timeline of Undertale (Presumably "Something New") Biography: He was once the classic Sans in an endless cycle of genocide, but at some point he remembered the resets and routes his Frisk had taken. Desperate to end the cycle, he met his Chara, who made a deal with him: kill all creatures in the Underground. This gradually made him increasingly bloodthirsty, to the point where he took Chara's soul, making him stronger and more determined than Frisk. Without the ability to save and load the game, Frisk was killed permanently. After Sans's timeline was completely destroyed by him, he went on a killing spree with other timelines before meeting Nightmare!Sans and joining his quest.

Killer!Sans looks significantly different from Classic!Sans. His jacket is slightly grayer than Classic!Sans's. The hoodie is light yellow instead of white. He wears a black turtleneck shirt, and a red target in the shape of a soul glows on the front. His shorts are inverted: instead of the usual black with a white stripe, they are white with a black stripe, and his slippers are replaced by sneakers the same color as his jacket. Killer!Sans' eyes are completely black, with black tears running down to his chin, like the blue threads on Error!Sans's face. However, in Underverse 0.6, his white pupils are occasionally visible. Killer!Sans has a psychotic, self-righteous, and hostile personality. He often kills monsters in his path and typically acts childishly when he "loses." But he's also very protective of his past, which is unknown in Underverse (except to him). He seems to have a penchant for knives...
