Time Switch

Lion-O and Tygra attempt to bury time capsules from the debris field of the flagship because the suspended animation gases are unstable. However, one of the capsules smashes against a rock during a mishap and the escaping gases envelope Lion-O in a red haze. In effect, Lion-O becomes younger at an accelerated rate. The Thundercats must find a way to reverse the process or Lion-O will become non-existent. After a tangle with the LunaTaks to get the Eye of ThunDERa/Sword of Omens at Lion-O's vunerable time, the Thundercats take their young lord to the Cave of Time to restore him to his approximate adult age.
