A member of the Evil Horde, he is an amphibian-like creature, of a large and bulky build with green skin and suction pads on his hands, feet and mouth. It is these suction pads that provide him with his main power: to suck and drain the life-force from his opponent, rendering them helpless against him.
Leech was introduced into the Masters of the Universe toyline in 1985, among the first wave of Evil Horde figures. His figure was packaged with the minicomic "Leech: The Master of Power Suction Unleashed!" It has large flat hands and a mouth which is a rubber suction cup, and can actually stick to flat smooth surfaces for short times if lightly moistened. This minicomic presents him as an immense sea monster summoned from the ocean depths by Hordak to fight against He-Man and the Heroic Warriors. A terrified Mer-Man also appears, with an unusual likeness: he has a bright red face and a black beard.
Leech appears in animated form in She-Ra: Princess of Power, in which the Horde are the main villains.
He is regularly seen among the main Horde members, but rarely showcases his power suction ability and receives generally little character development and no episodes feature him in a spotlight role.
also features in animated form in the updated Masters of the Universe cartoon series, produced in 2002 by Mike Young Productions, to promote the relaunched toy line. The Horde were intended to be released among the next wave of villains and fill the role of main opposition to He-Man in the show's third season. The second season episode "The Power of Grayskull" features the Horde in a flashback sequence, as an evil force from Ancient Eternia. Leech is seen among them in a non-speaking role, and was imprisoned by King Grayskull in the dimension of Despondos together with Hordak and the rest of the Horde. However, since the toy line and cartoon were canceled shortly afterwards, the third season was never made.
