I would like a "hell-ish" champ so to say.

I'm thinking some type of powerful demonic being, similar to the demon Belial or something. While there are many dark champion in the League of Legends I feel as if none of them really capture the "demonic" aspect. There are many champions I believe that portray the angelic side perfectly, and i just think it would be cool for them to have dark counterparts. We have Plants and Zombies, Ninjas and Pirates, etc., but I think it would be cool to have a Angels and Demons archetype instilled into the game as well. I understand Thresh and various others could very well represent what I am asking for, but I also feel as if they aren't essentially part of hell so to say and rather just "harrowing" type champs.
