Biography
When Skeletor overheard that one half of the Power Sword was hidden under Eternia's hardest rock, he sent Mer-Man to fight He-Man while Skeletor unearthed the other half from the rock where He-Man had built his house. After Skeletor left to Castle Grayskull, Mer-Man still tried to keep the hero preoccupied, but it was a losing battle once He-Man managed to recover his forcefield garment. With the help of Battle Cat, He-Man vanquished Mer-Man

At a later time, Skeletor was defeated in single combat by He-Man. who threw him into the sea, where he was rescued by Mer-Man, who offered to defeat the hero in exchange for keeping his weapons, which Skeletor agreed. Mer-Man got He-Man's Battle Ram and used it against Man-At-Arms' Wind Raider, but was finally defeated by Stratos' interference.

Skeletor decided to take vengeance on He-Man and called Beast Man and Mer-Man. He had both henchmen ambush He-Man on his way to a meeting with Teela. After they overpowered the hero, Mer-Man threw him to the sea where an undersea monster awaited, but He-Man was rescued by Stratos. After the evil henchmen returned with news of He-Man's death, Skeletor tried to break into Castle Grayskull only to find a very much alive He-Man with Stratos and Teela. After his minions were defeated, Skeletor fired his energy-blade on Mer-Man for his failure, but He-Man saved him. However, seeing Skeletor using energy blasts to punish his own minions gave him the idea of using the Heroic Warriors' own energy blasts to make the Evil Warriors flee.
