I'd say Bern after a long, long battle, but that's just me.
Piccolo from the Dragonball saga takes on En Sabah Nur AKA Apocalypse from Marvel Comics.
Two weeks of prep for both of them, and the fight takes place in rural Taiwan.
Who takes it? The green Namekian or the blue mutant?
Wilson Grant Fisk AKA Kingpin from Marvel Comics takes on Johan Liebert from Monster!
I know this might seem a bit one sided, but think about it...there's plenty of prep for both opponents, and while Kingpin's got the obvious physical advantage, Johan's got the mental and psychological one.
That said, it should be an interesting battle, especially since they both have all their powers, abilities, weapons, skills, wits, etc. The fight takes place in Beijing, China, and is to the death. Who takes it?
I have a feeling people are underestimating IT. IT is more than just a scary clown with some powers, IT's a cosmic force, with which the help of the Turtle (who vomited up the entire universe) was needed to beat.
My, oh, my! I should have remembered that about IT AKA Pennywise! I change my mind and say that Yuki loses, then. Sorry, Yuki.
Thanks for the correction. I'll edit my post and make things more accurate, although I'm glad that this turns out to be the good, even fight I meant it to be, albeit with a winner, namely Sailor Moon, as you've said.
I'll say Kenshiro.
