Thundercats: Season 1

When a meteorite the Thundercats can use to replenish their dwindling energy supply crashes on Hook Mountain, Lion-O must win a duel with the fierce Snowman before they can have it.

The Mutants convince Mumm-Ra to raise their ship from beneath the desert so that they may build better weapons and vehicles to more effectively battle the Thundercats.

The Thundercats search desperately for a precious device which has all the recorded history of Thundera up until the time of its destruction.

The Mutants devastate the Cat's Lair, the Warrior Maidens, and much of the surrounding countryside with a powerful long-range fire-cannon they have constructed on Castle Plun-Darr.

Mumm-Ra tricks Lion-O into using the Sword of Omens against another Thundercat, causing it to break in half. The only way Liog-O can restore it is to venture into the heart of a volcano.

Mumm-Ra switches the real Panthro with a clone infused with the spirit of Hammerhand and sets it free to cause terror and carnage, leaving the Thundercats to take all the blame.

Mongor, a terrible demon that feeds on the power of fear, is accidentally set free from his prison by Wilykit and Wilykat to terrorize Third-Earth.

Lion-O accidentally activates the time capsule, which hurls him back in time to Thundera exactly one day before its destruction. Meanwhile, the Mutants assault Cat's Lair with their most powerful and deadly weapon yet.

The Thundercats help an undersea professor to protect a machine that prevents the oceans of Third Earth from literally going down the drain.

Jaga is captured by Nemex, an evil being from the Astral world, and Lion-O tries desperately to find a way to rescue his old mentor.

Lion-O must brave an ice palace to save a sacred bird from a cruel and greedy queen's clutches.
