Geno has a similar appearance to Classic!Sans, although he wears a white jacket and slippers, as well as a version of Papyrus's scarf around his neck. His right eye socket is melted due to overuse of his determination. When he is serious, his left eye lights up with a blue and red tint. Geno seems very casual and relaxed. He doesn't seem worried about the threat of the X-EventHe's very sweet, but when he's angry it's very dangerous. He's a Sans/Skeleton. He considers himself Ink's older brother.
