LT!Sans: Not really much to explain. He looks like a normal Sans, but he wears small purple reading glasses and wears a purple hoodie along with purple boots. He very nerdy and scientific and is actually quite the workaholic. He can teleport things and people to him just as long as he knows where they are. He can also summon these swords similar to Asriel's swords in the True Pasifist Fight. He can also summon purple strings, but they aren't as strong as Error!Sans's strings or anything like that. LT!Sans, while being quiet and nervous, goes completely insane by the mention of RESETS, or what he calls them "SETBACKS". He will attack and kill and finds a thrill in the Genocide Run.
Corrupt!Sans: A little taller than the normal Sans. His left pupil is shaped like a spiked circle (which is a darkish pink). His right eye is pitch black with pink, spikey crystals coming from the top right of it and growing all the way to the side of his head. His teeth should have fangs, which nearly overlap his other teeth. He wears a yellow sweater, which is severely torn at the right shoulder, more crystals sprouting and growing there. His fingers are almost claws. He wore torn-up pants, a few crystals growing here and there and he wore black rubber boots.
