ThunderCats S01 E02

ThunderCats S01 E02 "Omens: Part Two"

Thundera is attacked by Lizards who have acquired salvaged technology. Grune has joined the Lizards and Panthro is being held hostage. Lion-O comes to his father's aid, allowing Claudus to rescue Panthro. Panthro fatally wounds the king, then reveals himself to be Mumm-Ra (an ancient nemesis of the ThunderCats) in disguise. With his final words, Claudus admits he is proud of Lion-O, then he dies in his son's arms. Lion-O tries to avenge his father, but he and Tygra are captured along with Jaga and Cheetara. However, because of his kindness to the Lizard prisoners that he had freed, Lion-O is given a key (hidden in his meal), allowing him to escape with Tygra to mount a rescue. Mumm-Ra wants the stone in the sword which he claims is his, and tortures Jaga to force him to remove a curse that prevents evil from touching the Sword of Omens. Lion-O and Tygra rescue Jaga and Cheetara (who is revealed to be one of Jaga's clerics). Lion-O grabs the sword to blast Mumm-Ra out into the open, and the rays of the rising sun harm him. Forced to leave Jaga, who sacrifices himself to ensure their escape, Lion-O, Tygra, and Cheetara undertake the quest to find the Book of Omens.
