basically-genius:

Houseplant Flowey AU: The game’s big bad evil guy is now a potted plant that does nothing but whine 24/7.

PTA Sans: Mysterious, lazy and pun-alicious skeleton adopts human child and attends PTA meetings at the child’s school. Literal skeleton suburban soccer mom.

Shitpost Gaster: Hidden character we know nearly nothing about. Countless rumors and theories try to explain who he is, where he come from and what he wants. The fandom headcannons him as a literal walking shitpost. Spouting things like “ayyy lmao you lil shit” in Windings before disappearing into the void.
