These two panels as featured in The Secret Files of Scrollos from issue thirty-five of the UK Masters of the Universe comic show Prince Adam shortly after accepting the power of Castle Grayskull. I love the way these two panels are illustrated; the first being rather dramatic as Prince Adam announces his mission as He-Man, with the second panel a reaffirmation of the friendship between Prince Adam and Man-At-Arms. Out of all the origin stories ever presented, this is by far my favorite. At some point in the future I will feature the entire story for your reading pleasure!
