Thing vs Savage Hulk with a twist
Instead of Danny Rand, Ben Grimm becomes the Iron Fist before his mutation. Full package of chi amping + healing + the Iron Fist, and his already high stats boost up to the same degree a humans stats boost up (So he can amp his strength, durability, and gain a much harder punch from an Iron Fist infused class 80 punch...)
He still fights like Thing though. Otherwise, I could just have made Danny a class 80....
Who wins?
