That's Zang Kong Type IV, at least if size of his inner multiverse translates to the scale he can fight at. It might not, which would be a problem, but I doubt it would be more than a single Stage worth of penalty - and apparently certain Armaments can win fights against certain Combat Stage Fifteen Cultivators, depending on specialty matchup, so if I can rent an appropriate Armament, I win.If I'm remembering my Marvel cosmology right, which isn't a given, God Emperor Doom was dealing with an infinitely large multiverse of infinitely large universes, somewhere in the Cardinality range. I don't think Drich or any other Commander ever got to that tier. Though, to be clear, my knowledge isn't encyclopedic on this topic. I could very well be wrong.
I don't think Nameless got there either, but I don't fully remember the last descriptions of his inner world.
(I'm thinking Procyon might actually be a good option. It'd depend on narrative themes, I think.)
