Trials of Lion-O (1)

The ThunderCats are ambushed by Slithe who is now assisted by Kaynar and Addicus. When Lion-O is knocked into the river and pinned down by the rocks, he finds himself in the spirit world where Jaga tells him that he must pass a bunch of tests in order to return to the living. The first test taking place in the simulation of Thundera's slums has Lion-O trying to figure out which Wilykit and Wilykat has the key to pass to the next test. The second test has Lion-O having to race Cheetara through a labyrinth. Back in the living, Tygra and the other ThunderCats managed to get free from their shackles, but Slithe, Kaynar, and Addicus escape with the Sword of Omens. Tygra vows to get the Sword of Omens back.

חבריו של לאיון-או מטילים ספק בהחלטותיו. הם נקלעים לקרב מול סליית והאחרים שבמהלכו לאיון-או מת. אבן הרוח נותנת ללאיון-או הזדמנות לקבל חיים חדשים.

En una región montañosa, Lion-O busca la orientación del Libro del Augurio para su próximo curso potencial: hacia arriba. Los ThunderCats hacen su camino a la montaña, pero o se oponen o compartir sus dudas con respecto al juicio de Lion-O como su supuesto los pone en peligro.
