Thundercats

The concluding trial in Lion-O's Anointment Trials pits him alone and weaponless against the evil Mumm-Ra.

With the Mutants and Lunataks gone, the Ancient Spirits of Evil give Mumm-Ra until sunset to destroy all the Thundercats, and to prove they're not bluffing, they exile Ma-Mutt. Mumm-Ra spreads destruction all over Third Earth, sends Tygra, Cheetara, and Panthro to limbo, and buries Lion-O alive. Then he attacks and destroys the Tower of Omens, and the Thunderkittens barely escape, but Mumm-Ra sends them to limbo too. Snarf must go into the Book of Omens to find out how to defeat Mumm-Ra. Jaga and the Thundercats in limbo go into the Eye of Thundera to help Lion-O free himself from his rocky prison. Lion-O then battles Mumm-Ra at Cats Lair and finds out from Snarf that Mumm-Ra only has until sunset to defeat the Thundercats. Mumm-Ra fails and the Ancient Spirits of Evil banish and exile Mumm-Ra from Third Earth. With all their enemies gone, the Thundercats decide to permanently return to New Thundera

On the second day of his trials, Lion-O must race Cheetara through the dangerous lands of Third Earth. Although Cheetara is by far the fastest among the Thundercats, her speed can only last for a short time period. Lion-O takes a shorter but more dangerous route to make up for Cheetara's advantage.
