The MUTANTS form an unholy alliance with MUMM-RA and set forth to destroy the THUNDERCATS. LION-0 uses his mighty Sword of Omens for the first time as he lets loose with his thrilling call: "THUNDER-THUNDER-THUNDER THUNDERCATS ... HO!" A beam of light streaks from the hilt of the sword and projects the image of the roaring cat in the sky for the others to see. The sword grows in length and strength as LION-0 wins in his first encounter with MUMM-RA who has transformed himself into a fearsome warrior from another age. "Where evil exists, MUMM-RA lives"!

Lion-O is taught to respect all life and that all living things have as much of a right to life as he does. Those who practice evil do not respect the rights of other creatures nor do they feel mutual obligations among each other. Often their evil has penetrated so deeply that they do not respect even themselves. Lion-O learns in this episode that evil's worst enemy is its own unspeakable face.

Growth in morality involves an understanding of reciprocity and equalitarianism. Rather than being self-centered and guided only by an orientation to punishment and obedience, children must be taught to consider the expectancies of others as well. This development is aided by recursive thinking, learning to view the relation of oneself and another from the point of view of the other (Flavell, 1968).
