@Dream: universal? I was under the impression that Pennywise was nigh omnipotent. The Turtle is nigh omni, and he matches him, after all.
@Chef_Banchou: Based off what I'm looking up Pennywise, he resides from what is pretty much the equivalent of hell in Steven King novels. Unlike Gan and Maturin, there's more of what we've seen that he could do.
Also, there have been entities within Marvel Comics that are nigh-omni yet are only universal-level in power like Eternity, Infinity and Death.
