When you think about it, Chara is really the hero of the genocide run because they're the one who finally puts a stop to you and forces you to true reset. Especially how they tell you not to germicide again if you do it a second time.
I wish this would ACTUALLY happen! The two lazy-bones battling... That'd be AWSOME!
