Forgive me if this has been mentioned before--I haven't had time to read through the whole thread yet--but I wonder if he's called 'King He-Man' because that's exactly what he is? In other words, there's your everyday King Adam, who's married to his Sorceress-Queen Teela and raising Dare. When evil threatens, he pulls out the trusty ol' electronic power sword created by Duncan, and transforms into his powered-up form like in days of old--becoming King He-Man. Perhaps the outfit we're seeing here (with its garish coloring) is the equivalent of the silver harness that appeared when Adam transformed into He-Man in the olden days, and when he's de-powered (i.e., King Adam) he wears a much less garish, more kingly attire? This would enable Mattel to one day release a King Adam variant (*shudder*).
