Wiki!Sans

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.

Not much is known about Wiki!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. Wiki Sans likes to mess with people. He is also very awkward and sometimes shy.

Wiki!Sans can shapeshift into other undertale character, although very poorly.

Wiki!Sans can corrupt and alter data on the undertale wiki, and possibly other wikis as well.

Wiki!Sans can summon Gaster Blasters, use telekinesis, pyrokinesis, bone manipulation, light manipulation (manipulate how dark the surrounding can be), and teleportation.
