He normally appears as a perpetually black-lit sans with white eye sockets, black pupils, an open toothy mouth, and an orange outline. Although he can take other forms such as Flowey or Mettaton, he prefers to stay as (and pretend to be) a Sans, He rarely speaks, but when he does he often quotes lines from Undertale in unrelated contexts. He acts more like someone poorly roleplaying as sans than actual Sans. He is obsessed with Undertale's lore and trivia, spending all available time going over the known data. he likes to mess with people. He is also very awkward and sometimes shy. Abilities: Shapeshifting: he can shapeshift into other undertale characters, athough very poorly, Wiki corruption: he can also corrupt and alter data on the undertale wiki (and possibly other wikis as well)
