The most powerful man in the universe. He-man was given his tremendous strength by the power of Castle GraySkull. The Sorceress gave the sword of power to Prince Adam on his 18th birthday. Whenever trouble threatens Eternia, Adam holds aloft the sword and transforms himself into the mighty champion He-man the defender Castle Grayskull. His chief task is to falter the various schemes and machination of Skeletor, Hordak and King Hiss, who will stop at nothing to take over Eternia. At He-Man’s side are the ever faithful BattleCat, King Randor’s royal army and the heroic warriors. He-man is sworn to protect Castle Grayskull and must display the dignity and honor that his duty demands.
He-man is usually the first to prefer resolution compromise before resorting to violence. Even when Skeletor endangers himself He-man will come to his aid. Randor comes to rely on He-Man to solve the problems of his kingdom. Physically He-man's most impressive quality is his strength which is on most occasion without equal except for Faker. His super human strength comes from the abyss beneath Castle Grayskull which feeds the castle its power. When He-man squares off physically against Skeletor’s villains he usually looks for non violent ways of battling them. While He-Man’s powers are mainly physical he also possesses a deep rooted sense of morality. Being trained by Man-At-Arms he sometimes uses his knowledge of science to solve problems.
He-Man is not invulnerable and can be thoroughly drained from exertion. The chest harness that he wears was fashioned by the Sorceress from Coridite, and helps add to He-man’s incredible power. The Sword of Power’s main purpose is to act as a conduit for the power of Castle Grayskull and is used to transform Prince Adam into He-Man and Cringer into Battle Cat. But he also uses it as a useful tool to deflect laser blasts, smash apart blockades and pry open tight areas. He-Man is a testament to strength and endurance both mentally and physically.
