Curate, connect, and discover
(So this is basically a theory I came up with to explain all the wildly different interpretations of canon Chara and how practically all of them are correct)
Chara A: The Chara that existed from their birth to their death. A self loathing, Misanthropic with Psychopathic traits. Though, this version of Chara isn’t an actual Psychopath. Despite being a dick, they still care deeply for their family and monsterkind, and was willing to sacrifice their own life in order for them to be free. Albeit, along with their own goal of purging humanity.
Chara B: The Chara created during the Neutral Run. This version of Chara is probably the least developed since unlike the pacifist and Genocide, none of the player’s actions really reawaken Chara, so this one has the least personality.
Chara C: The Chara created during the Pacifist Run. Learns to forgive humanity and overcome their violent nature through peace.
Chara D: The Chara created during the Genocide Run all because of the Player’s actions. A sociopathic serial killer who just wants to see everything wiped out.
