[@Renny] I'll wait on Poly's thoughts but a kryptonite factor could be the answer. There are some very powerful characters in the RP, but yours is physically above all of them at the moment. Usually in an RP characters that powerful should be NPCs or Villains in my experience but we'll see. Also again if you're going with a cosmic backstory, I would be interested in seeing how that is fleshed out, but again he shouldn't be classified as a metahuman. He's entirely different. I'm also thinking he should look more otherworldly than he does.
