Asriel in his god of hyperdeath is without a doubt the strongest character because he has the equivalent of 7 souls and thus is basically a god. Having the 7 souls he can also destroy the world AND destroy the barrier, he can also manipulate reality and change his form at his will. All Chara can do is to destroy the world and recreate it and so only because of their ability to destroy Frisk's save file (which is why you CAN'T get your save file when you when Chara destroy the world) and because of their reset ability.
