S-S-Slithe: Leader of the evil mutants on Third Earth
Monkian: He is a mutant with much brawn but little brain. He can maneuver easily admist the treetops, and
wields a magic shield capable of firing cannonballs or energy blasts.
Jackalman: A canine mutant skilled with the axe. He can sometimes be more ambitious for his own good, but
is often too cowardly to fulfill his aspirations.
Vultureman: Perhaps one of the most ambitious of all the Mutants, Vultureman is a
dangerous and crafty inventor. It is he who is responsible for all the
Mutant technology and weapons of destruction. However, his loyalty to
his fellow Mutants is questionable, as he has often allied himself with
Mumm-Ra or the Lunatacs instead.
Plundarian Warbot: A virtually indestructable war machine. Lion-O discovered it's weakness after traveling
back it time to just before Thundera was destroyed
