He has no name yet, all I have for him is he was a knight, bringer of good and justice, captured, tormented, transformed and almost killed.
Escaping from prison his body was still under the effect of the corruption, his will broke the chains of the enemy influence and was able to keep his sanity (well, most of it).
His body is still a death trap, if he loses control, the infection takes over and do horrible things.
Design wise, when the infection takes over, the fiery plasma inside him is glowing, pulsing, when he fights it the crystals on his armor/body are glowing.
I kinda want to work on him and submit my ideas to RIOT games to be a possible league of legends champion.
