Mer-Man
and Beast Man team up and basically beat the crap out of He-Man. Stratos
rescues our hero (again) and the two, with Teela, go to confront Skeletor
and his cronies at Grayskull. Mer-Man and Beast Man each try to outdo each
other while fighting He-Man but just end up hitting each other by accident.
Then they retreat.
