Slithe or S-S-Slithe is the leader of the Mutants and a very dangerous enemy of the ThunderCats. Although lacking sophistication, he can be very cunning. Domineering and impatient, Slithe often must browbeat the other Mutants into going along with his plans. He has a tendency to emphasize on pronouncing the letter "S" in his speech, usually ending his sentences with the question, "Yes-s-s?" He also holds little to no respect for Mumm-Ra.


Unlike Jackalman and Monkian (whose appearances are identical to other mutants of their kind), Slithe stands out from other Reptilians because of his ears. Slithe has a rather stocky build. He also possesses a strong muscular tail which he often uses as a weapon by swinging it and knocking his opponent off their feet.

Character information


Slithe once served as Ratar-O's cook earlier in his career, and he retains a discriminating palate.

Leadership Skills

The self-appointed leader of the Mutants on Third Earth, Slithe is often ruthless, cruel and always without remorse. One of Slithe's greatest weaknesses as a leader is his arrogant personality, Which often leads to overconfidence in battle, also he's often considered an unpopular leader with the other Mutants.

However it should be noted that many of the Mutants, including Jackalman and Monkian prefer his leadership over that of the well known and highly regarded General Ratar-O.


Slithe often demonstrates a very dry and sarcastic wit. Usually reserved for insulting his own troops. Sarcasm is often used by Slithe after one of his men has accidentally stated an obvious fact.
