Here I present the final three pages of the story that changed the life of He-Man in the UK Masters of the Universe Adventure magazine! "A New Beginning" marked the start of The New Adventures of He-Man and the magazine title was changed simply to He-Man. In this story we see how He-Man and Skeletor leave Eternia, amass their respective forces, and start their ongoing war in the Tri-Solar Galaxy! I love the action in the panels depicting the fight between He-Man and Skeletor. Also, it is worth noting that we see that He-Man's Sword of Power actually transform on the final page!
