Early in this canon, Mer-Man's Sword projects streams of ice, that freezes anything upon impact. It also is shown to fire ice pellets at the enemy.
1983 MOTU/POP Ladybird Books Canon:
Mer-Man is armed with a rather strange-looking sword, that can unleash powerful blasts of Zero-Energy (icy cold blasts of energy, that will freeze anything it strikes). He used it once to capture Teela in a frozen Bubble of crystal-clear ice.
2002 MOTU Mike Young Productions Animated Series Canon:
Mer-Man's Sword did appear in this canon.
- In the 1983 Ladybird Books, Mer-Man's sword was a more powerful, magical weapon, than in any other canon.
