Episode Summary

The Thundercats briefly show Lion-O how the time capsule they recovered from the caveman works. Curious to see more, Lion-O activates it during his night-time watch, and gets caught in it nuclear projection rays. The rays send him back in time to Thundera, just before the final tremor that destroyed the planet. Meanwhile, the mutants have built an evil robot monster that is destroying the cats lair, and the other Thundercats. Back on Thundera, Lion-O encounters his father, Claudus, and saves him from a mutant attack. In return, Claudus gives Lion-O the plans to the robot that was destroying the Thundercats in his own time.moreless

    Trivia, Notes, Quotes and Allusions


    • TRIVIA (3)

      • Prior to Lion-O meeting his father on Thundera, the ThunderKittens were with the others in Cats Lair as the Warbot approached. But after Lion-O met his father, the ThunderKittens were never seen again in the rest of the episode.

      • Sword Powers: (first use) "Power Beyond Power" - Lion-O can use the sword to reflect an enemy's power back at them.

      • Lion-O arrived on Thundera the day before the destruction of the planet and left the next day when Thundera was destroyed. When he returned to Third Earth, it was still the same night as when he had left.

    • QUOTES (6)

      • Lion-O: I should have saved [Claudus]. I tried, but he wouldn't leave.
        Panthro: No, Lion-O. There was nothing you could do. No one can change history. We can only learn from it.

      • Panthro: Never thought I'd live to say this, but, ThunderCats, stand by to abandon Cats Lair.

      • Claudus: I thank you for your help. May my son Lion-O grow up to be as brave and noble as you and carry on the sacred code of Thundera.
        Lion-O & Claudus: Justice, truth, honor, loyalty.
        Claudus: The tremors grow worse. Go! While you still can.
        Lion-O: Farewell, father!

      • Claudus: I lost my sight fighting your evil empire. Do you think I fear two such as you?
        Slithe: You cannot see, but you can feel!

      • Panthro: Mountains of Thundera! Look at this, ThunderCats!
        Cheetara: A giant robot.
        Wilykat: Yeah, a nightmare version of that reptilian rascal Slithe.

      • Lion-O: Thundera! I can hardly believe it! It's just as I dreamed it would be.
        Jaga: It may not be as you imagined it, Lion-O. Take care that your dream does not turn... into a nightmare.
