So basically his armor is made out of Cold Iron and Beastium (The strongest metal in the universe where mrbeast runs the economy) and he shares a lot of the same powers with the collector.
By using the commands blocks in his arms He can summon things, create matter, transform things, and destroy matter. in his torso is bill cipher eye, which can be swapped out with cuphead's head to do the Super 1. He also has sans' abilities. And the Collector may have totems of undying but Zanthor can actually turn them into totems of dying using the command blocks in his arms.
So im ready Dr. Evil-ish
