Verily, the man of steel doth be a worthy challenge for the son of Odin, but he doth lack the mettle of a true warrior born...Thor is the god of the very thunder and doth commandeth the elements of the sky!!! Thor hath also faced down many an adversary that would surely dwarf the man of steel's opponents...hast thou forgotten that Thor hath faced down Mephisto? He beith the very essense of true evil incarnate...or what about Hela, the ruler of Hel itself?!? Verily, thou hast heard of Thor's victory over the serpent that encoils Midgard herself? Mortals call it The Midgard Serpent. If the god of thunder canst strike down these base villains, then verily he shalt not have a problem with the one called Superman...
ODIN HATH SPOKEN!
