Hmmm...
Ironic that "wrestling is fake" but apparently stories of 2 guys such as Captain America and Spiderman - who also fight in pre existing story lines where the outcome is known to those writing - and also wearing brightly colored tights - and also have strange abilities normal people don't usually posses (well, not Kurt Angle, but crap like the Undertaker and stuff) isn't "null and void"... just a thought...
Besides, Goku would lose to Squirrel Girl
From what I've seen she took down every major Marvel Comics villian near single handedly, at least back when I read comics. She might be dead now...
