Ultron

ultron has reincarnated as a grey liquid metal being. his goal is to take over powerful people/heroes by enveloping them in the liquid metal. he cannot talk. it will directly attach to their skin under their clothes, starting with their feet and legs, then their crotch, then their chest and arms and finally their head. once a host is fully enveloped, the host will slowly go limp/unconcious, and the grey liquid metal will begin to solidify into armor, making their entire body look like ultron. a mask will solidify over their face, which has glowing red eyes and no mouth. they can now speak as ultron, with little emotion. ultron now controls their entire body as well as their powers, and wants to take over the world and/or spread the metal to other powerful hosts.
