His body fell to the floor and smashed into pieces, but he was restored to life by Skeletor, breathing a sigh of relief as his body reformed. Later, Mer-Man attempted to engage Snake Face in combat when the Snake Men returned and seized control of Snake Mountain, but was turned to stone before he could land a blow. Man-At-Arms was rescued by Teela, and Mer-Man next turned his attention back to the Coridite crystal, which Skeletor had forgotten about Mer-Man attempted to use the crystal for himself, but found its powerful difficult to control. Mer-Man joined Skeletor's assault on the Royal Palace of Eternia and kidnapped Man-At-Arms, having his enormous, flying fish-pet devour him whole.

Soon after, Mer-Man joined Keldor and fought alongside him during the battle of the Hall of Wisdom, after which he was imprisoned behind the Mystic Wall in the Dark Hemisphere.

Though Mer-Man won the battle against Aquarus, he returned to find his own kingdom in ruins. He became embroiled in a battle with his rival, Aquarus, over another underwater settlement not yet under his control. Mer-Man was the self-appointed 'king of the seas' and ruled his own underwater kingdom. He also attempted to seal the Variable High-frequency Oscillator for his own sinister ends. Mer-Man would later strike out alone, using the Pearl of Power to subjugate the underwater city of Aquatica and mind control its people. Twenty years later, Mer-Man attempted to sacrifice Man-At-Arms' daughter, Teela to the same demon, but was foiled again, this time by He-Man and Zoar. The plan was foiled when Zoar was rescued by Man-At-Arms. Mer-Man once attempted to sacrifice Zoar to the Sea Demon, Bakkull, which would have allowed him to command Bakkull, the mightiest of the sea demons. Mer-Man had telepathic abilities which allowed him to control other sea creatures, and had own aquatic henchmen who served as his footsoldiers. Though he reported to Skeletor at Snake Mountain, Mer-Man usually dwelled within the seas themselves, and often operated independently of Skeletor and the other Evil Warriors engineering his own water-based schemes. Hailing from the Crystal Sea, Mer-Man was an aquatic ocean warlord in service to Skeletor (Filmation). Some time later, Mer-Man was attacked by Leech of the Evil Horde. Mer-Man tossed He-Man's body into the sea, but he survived and returned to defeat Skeletor and his henchmen. He was later summoned by Skeletor in an attempt to captured Castle Grayskull, managing, along with Beast Man, to knock He-Man unconsious.

Mer-Man managed to successfully steal He-Man's harness and Power Sword, but was defeated by Stratos. He sought to be Skeletor's equal, and to that end, offered to help Skeletor defeat He-Man in exchange for his weapons, believing they would make him just as powerful as the Lord of Destruction himself. Mer-Man was one of Skeletor's earliest minions. Character history Minicomics Main article: Mer-Man (early minicomics)
