Original Airdate November 12, 1985
Episode Number 37
Written By Leonard Starr
Season 1

This is the first episode in the story arc "Lion-O's Anointment Trials."


On Lion-O's 20th birthday, he must pass a set of trials to become the true Lord of the ThunderCats. Even though he is the hereditary Lord of the ThunderCats, he has not proven himself to be worthy of that title. Yet. Lion-O must prove that he is the rightful Lord of the ThunderCats by facing his friends and fellow ThunderCats alone and unarmed.

His first test is to beat Panthro in a duel to test his strength. He proves himself superior to Panthro when the latter is trapped beneath a boulder from which the "strong-cat" of the ThunderCats cannot free himself; Lion-O instead frees Panthro from the latter's entrapment beneath the boulder.





  • Whilst Lion-O is talking about what he needs to do to pass the Trials, the footage shown of Panthro, Tygra and the ThunderKittens is taken from the "lost intro" from the "movie" version of Exodus, the Movie.
  • This episode is one of very few in which Liono-O does not perform the famous "ThunderCats Ho!" chant.
