You'd cheer anything which changed her personality, up to and including decapitation. An evil wizard agrees and gets her hooked on a magic potion. He-Man, who secretly hides from his friends to inject magic strength-boosting power into his body with a pointy metal implement at least once every 27 minutes, disapproves.

He couldn't have been more hypocritical if he'd started campaigning against fur and public nudity, and his brilliant plan is to call the dealer and start a fight.

Fortunately, irony bounces off He-Man like lasers and h**oerotic subtext.
