It has been ten years, the Thundercats have brought peace to New Thundera and have grown to a population of over 20,000 on their planet alone, 10,000 stay on Third Earth.
Now, thanks to a group of Thunderians willing to do anything for their race, they have begun to populate another planet nearby.

Times have changed, and the race had advanced in technology.
While Lion-o and the Thundercats keep their home safe, Panthro lead a dozen Thunderians to a nearby planet.
It's been 12 months, they have built a small city with aid from the Thundercats and from their people visiting from time to time.

Travelling across the galaxy comes a whole new evil, the Archangel of Destruction, and the new planet Thundera Alpha is in his sights.
He is not alone, from deep beneath the sea, a new evil rises....a being with majiks that sith through his veins.

Neither evils have a master plan, just the lust for adventure, pleasure...and selfish needing.
Will Panthro has what it takes to fight for the freedom of the planet he rules?....
