| Mutants |
| Jackalman Another member of the mutant army and like the rest of his arm, almost never succeeds with his commands to destroy the ThunderCats. When he uses a weapon, it's always a spike club. Commonly travels around one of the two Sky Cutters but has been in the Nose Diver a couple times. |
| Slithe This reptilian is the leader of the mutant army. He always speaks with a hiss. While he is fairly strong, he isn't very bright and almost never succeeds in his attempts to beat the ThunderCats. He had his ship follow the Thundercats to Third Earth. He commonly travels around in the Nose Diver but has traveled in the Sky Cutter. He believes himself to be smarter and better than Mumm-Ra and questions Mumm-Ra's plans--though never to his face... |
| Monkian Monkian is also a member of the mutant army. And, yes, this one almost never succeeds with his commands to destroy the ThunderCats as well. He has a shield that will fire out fire balls and other useful weapon that will slow the Thundercats down. Commonly travels around one of the two Sky Cutters but I believe has been in the Nose Diver a couple times. |
| Vultureman Mutant genius. Just like Panthro, keeps up with building new inventions. The inventions always work, that is until the Thundercats realize what new angle the mutants are playing. Keeps trying to build things that will defeat thundercats. When present at a battle, he is usually the last one to (willingly) retreat. He will also betray his fellow mutants to reach his own gain but always manages to get in goods with Slithe after returning back. Vultureman's main way of travel is by his Flying Machine, which is one vehicle he invented. In fact he invented all the Mutants vehicles and other gadgets that is used against the Thundercats. |
