Cruel, cunning, cowardly and driven by ambition, Jackalman grudgingly serves under the leadership of S-S-Slithe in the hope of one day seizing ultimate power for himself. Like all the Mutants, Jackalman is loyal only to himself - initially easily impressed by the grandiose leadership style of S-S-Slithe, Jackalman's loyalty to the Reptillian leader gradually waned over the course of their many defeats at the hands of the ThunderCats. More intelligent than Monkian, but hampered by his cowardly nature, Jackalman's lust for power is rivalled only by his hatred of the Mutants' sworn enemies, the ThunderCats and their friends.
