@Riot How About A Split Personality Champ?
I think it'd be cool if we had a champion with a split personality or tourettes. Like a peaceful monk or something that's corrupted by void energies or is a shadow isles being that is only half-dead in which his or her more compulsory emotions occasionally take over. Or perhaps a warlord who randomly spits out nice things. "I HOPE YOU DIE, comfortably, surrounded by the ones you love." [Idk, I tried to be funny.]
But not something like
who is literally 2 personalities.
More like
's line "Don't let the door hit you, where the good lord split you ON YOUR WAY TO HELL."
doesn't really fit this, she doesn't look she is bipolar.
