The greatest gift Masters of the Universe: Revelation gave to He-Man fans was character growth. The first series, produced by Filmation, was syndicated, meaning there could be no serialized continuity. The most important episode in MOTU: Revelation to do this was "The Most Dangerous Man in Eternia." It's the beginning of the characters' journey toward healing from the trauma the villains inflicted on the heroes.
