ThunderCats wiki

Monkian is a member of the evil Mutants. He is the leader of the Monkians from the planet Plun-Darr.


He was with Slithe and Jackalman and all their respective armies on the Mutant Mothership, chased the Royal Flag Ship for the Eye of Thundera in the hilt of the Sword of Omens. This was right after Thundera had met it's fate.

After taking out all the other Thunderian Ships, they used grappling rays to hold the Royal Flag Ship as the Mutants including Monkian came on board. While Jackalman and Slithe had teamed up searching for the Eye of Thundera, Monkian was elsewhere on the ship. Later Jackalman and Slithe fled back to the Mothership, which everyone else followed including Monkian. Years later, right after the Royal Flag Ship crash landed on Third Earth the mutants caught up with the ship. Along with the mutants, Monkian came down to the surface to search for the sword. Monkian's finds and starts trying to destroy a suspension capsule near him; however, Lion-O called to his fellow ThunderCats, which woke and released them from their capsules. Quickly seeing that they were losing against the ThunderCats, Slithe tells everyone to retreat.

Physical Description

As a Monkian, his namesake and species; he is a humanoid monkey. He has white fur and and tan skin. He wears his spiked helmet, however unlike the rest of his army he is shown to have it visibly not strapped on, with the strap hanging down to his shoulders.


Monkian normally never quarrels with any of the Mutants but occasionally is shown to be mildly rebellious toward Slithe. In the episode "Eye of the Beholder", when Monkian tells Jackalman that the Sword of Omens is unguarded, Jackalman suggests they should tell Slithe, but Monkian asserts the two of them should instead work privately as a team; then, once they have the Sword, they can put Slithe back in the kitchen where he belongs. In another episode, "Trouble With Time", Slithe and Monkian complain about the quality of their food while Jackalman seems to enjoy it; Slithe instructs Monkian to find a cook, saying that a woman's touch is needed. Monkian mumbles to himself, "Chauvinist reptile," but when Slithe then demands to know what was said, Monkian quickly complies with the order.

Monkian may not be very fond of Slithe at times, but he and Jackalman prefer Slithe's leadership over Ratar-O. When Ratar-O first arrives in the episode "The Feliner", he barks at the Mutants to stand at attention and to call him sir. Slithe, Monkian, and Jackalman decide to go along regardless of this harsh treatment because they think Ratar-O's plan could work, but the three of them are clearly uncomfortable submitting to such orders. In the second part of the episode, after Ratar-O's plan fails, Slithe assumes command once again and promises Vultureman and Ratar-O that he will settle with them later. Monkian and Jackalman instantly back him up despite later facing Ratar-O's displeased punishment as effected by the fearsome Rat's Eye power emanating from his two daggers.

In some cases, Monkian's ignorance hurts the Mutants' plans to defeat the ThunderCats. In the episode "The Fireballs of Plun-Darr", Monkian is eager to blast the intruders from their new fuel room which is capable of launching fireballs over long distances. Tygra, Lion-O, and Willa seal the door, but once Monkian melts it down, his weapon inadvertently sparks into the room to ignite the fuel, setting off a flurry of explosions which destroy the fireball launcher and tear through Castle Plun-Darr.

Despite sometimes seeming mentally challenged, such behavior usually brings out the humorous side of Monkian's character. For example, in the episode "Trouble With Time", when trying to explain his findings about the Thundrilliam, Monkian is so hyperactively excited that Slithe must tell him to slow down. The Mutants manage to piece together what he is attempting to communicate before he actually gets the chance to explain, at which Monkian disappointingly sighs, "That's what I've been trying to say!"

Powers and Abilities

He is shown to be not such a great fighter, however he does okay with his Ball and Chain Flail, he frequently uses.

While Monkian may not be the smartest of the Mutants, he is a very good spy. It is usually Monkian who obtains information about the ThunderCats. In the episode "Trouble with Time", Monkian learns that the ThunderCats are searching for Thundrilliam which fuels all their equipment. When he informs the other mutants, they agree that they must prevent the ThunderCats from finding their fuel so that the Mutants will have an advantage. Sometimes Monkian secures knowledge indirectly from his informants. For example, in the second episode of the "Anointment Trials", Monkian tells Slithe that his information came from his best source, a female whom he claims to have met in a tree. Nevertheless, Monkian plays a key role for the Mutants.
