ThunderCats wiki

‘’Thundercubs, Part 1" is the ninety first episode of ThunderCats (original series)


Mumm-Ra learns of the Treasure of Thundera and the Sword of Plun-Darr which destroyed Thundera. He and Ma-Mutt "travel back in time and space" to explore the debris of Thundera and look for the sword, which causes the planet to reform.

The Thundercats find out about this and must make the journey to New Thundera to stop Mumm-Ra. Lynx-O and the Thunderkittens are left at the tower while the other Thundercats at the Lair are preparing the Feliner for the trip to New Thundera.

Vultureman notices that the tower is only guarded by three Thundercats and goes to Sky Tomb and tells Luna. Luna then sends Red Eye and Tug Mug to attack the Tower, and they capture Lynx-O and the Thunderkittens.


Impulse and losing your temper can cause you to get into very big trouble. Don't lose your composure and forget to think first.
