May go with Jack Christian if you kill me I swear to Cthulhu I'll [REDACTED]. He is calc-less, but his feet seems stronger than Nightmares, and it was done casually. He is more skilled, and has Chi manip. Main issue for Jack is that he will hold back....now that I think about this I might say Nightmare. He doesn't and wouldn't hold back, like Jack does (under his weakness at least). I mean his weakness is "Almost always restrains his strength when fighting people. Rather cocky and overconfident, which superior fighters have used against him at times."
