Fanon Chara: ''A demon who wants to kill everyone in the Underground. Manipulated the Dreemurrs. Gets the player to commit mass murder of the monsters, despite Frisk wanting to spare everyone. ''

Canon Chara: A fallen human who was befriended by the Dreemurrs, eventually being added to the family. Then the soul you control in Undertale, deciding the monster's fate via sparing or killing them.

Headcanon Chara: Narrator Chara. Enough said.

Fanon Flowey: ''A soulless flower who wants everyone to die and become God/A flower who is redeemed by Frisk and spends eternity in a flower pot. ''

Canon Flowey: The remains of Asriel's soul, stuck into a flower. Is the result of Alphys' experiments. Becomes Asriel in the pacifist run, before supposedly reverting back into Flowey.

Headcanon Flowey: Basically Undefell Flowey.

Fanon Sans: '' Mary sue who will kill you if you dare to kill his bro. Is the most powerful enemy EVER,  beating out The Dreemurrs (Asriel and Asgore, not Toriel). Loves ketchup and puns. ''

Canon Sans: A lazy goofball who uses his true power only if everyone he knew was killed. Only drinks ketchup ONCE, and only tells bad puns when his bro is around.

Headcanon Sans: Basically Fanon sans, just tweaked a little bit.
