The few times KK has appeared in comics he has exhibited greater strength levels than I've seen the Thing exhibit. Any superhero can bend steel (as KK can), but not every superhero can karate chop a space ship into two (as KK, again, has).
Thus it is more like VASTLY superior skill and strength vs strength.
The Thing will not even know what hit him.
Oh, lol.
Yeah, Daniel son would lose, horribly.
There is another guy called Karate Kid, he's mastered every fighting style to ever exist.
He's a beast.
The Karate Kid we're talking about has normal strength, but can amp his chi. He punched a 10 foot wide diamond in half.
He uses perfect skill instead of brute strength to break mountains and steel star ships.
