Mumm-Ra plays deception with the Thundercats when he (disguised as Jaga) tells Lion-O that the Thundercats at the Tower of Omens will rebel and take Third Earth for themselves. Then he disguises himself as a Tuska warrior and asks the Thundercats at the tower for help. Ben-Gali, Pumyra, and Snarfer go to investigate while Lynx-O calls on the others to help, but Lion-O warns the others of their possible treachery, but Panthro, Cheetara, and Snarf go anyway but somewhat cautious. When they meet, the Tuska warrior "accidentally" causes the newer Thundercats to attack. He then disappears and the Thundercats start fighting each other. Meanwhile the Lunataks invade Cats Lair and the Tower of Omens. Lion-O must call on the Thundercats hoping they'll stop fighting each other to defeat the Lunataks and Mumm-Ra, which they do.
