His gem of Cyttorak (think that's how you spell the name) is the gem of some mystical God-like being. Gives him unlimited physical strength. As in, no solid opposing force could do too much. Very efficient at ignoring magical/ some cosmic "magics". He's so ridiculous, the Hulk had to literally become the embodiment of a Horse from the Apocalypse to stop him once he started moving. Requires equally unlimited strength to stop him, essentially. He also requires no form of sustenance or anything else that would define him as a human (ie fckn oxygen lmao).
