Galitzine has previously shared a behind-the-scenes glimpse of his take on Eternia's muscle-bound protector, and to celebrate his birthday, the actor has now posted a training video which sees him wield He-Man's Power Sword while fending off a group of attackers (Skeletor's goons, presumably). By holding the sword aloft and saying the words "by the power of Grayskulll," Prince Adam is able to transform into He-Man. Galitzine is not in costume here, unfortunately, but he did also share another BTS shot of his Prince Adam look (you'll have to scroll through to the end to check that out). FIRST LOOK: HE-MAN on BATTLE CAT! After tracking it down almost two decades later, Prince Adam is whisked back across space to defend his home planet against the evil forces of Skeletor.
