Trials of Lion-O (Part 2).The surviving ThunderCats made it to Mumm-Ra’s temple (the original spacecraft that crash-landed on Third Earth). Half-completed his trials in the spirit world, Lion-O ends up in a test of strength against "Panthro," where he must knock Panthro out of the ring before the sands within the hourglass run out. Lion-O couldn't ring-out Panthro until he remembers that he is the king and simply orders Panthro out of the ring. Panthro states to Lion-O that his greatest strength is being a leader. Meanwhile, the ThunderCats quietly took out the external Lizard guards and Panthro help gain entry to the ship.
