The Thundercats storyline begins with the planet of Thundera. Thundera has inhabitants called the Thundercats who are cat-humanoids. Thundera is ruled by the Lord of the Thundercats, Claudus. As the story opens Thundera is under siege by a race of beings called The Mutants. The Mutants are comprised of a lizard/snake humanoid, an ape humanoid, and a jackal humanoid. Somehow the Mutants are going to blow up Thundera, and the nobles of this world are fleeing in a spaceship. These nobles become the main characters in this series. The Thundercat adults are comprised of Jaga, Tygra, Cheetara, and Panthro. They also brought two children, Wilykit and Wilykat. Finally, the next in line for the Lord of the Thundercats position, a small cub name Lion-o with his chamberlain Snarf. Snarf is a catlike creature whose tail can be used as an extra appendage to balance or grab things with. The nobles enter stasis pods on the ship to allow them to travel without aging while Jaga agrees to fly the ship.
This ship is being followed by a ship of Mutants and crashes on the planet of Third Earth. All the Thundercats survive except Jaga. He is killed in the crash. Upon coming out of the pods it is discovered that Lion-O’s stasis pods was not working. All of the Thundercats remained the same age during the flight while Lion-O aged to an adult. As an adult he is now the Lord of the Thundercats, and the group decides to remain on Third Earth and build a fortress, called Cat’s Lair.
Lion-O carries the Eye of Thundera, the source of the Thundercats’ power. The Eye is embedded into the hilt of the Sword of Omens which is wielded and responds to the current Lord of the Thundercats. Lion-O also has a shield called the Thundercats Claw. The Sword of Omens and the Eye of Thundera cannot be used for evil or against the Thundercat.
The Thundercats learn that Thundera was not fully destroyed and strive to return to search for survivors and the treasure of their people. Upon returning three more Thundercats are discovered. Pumyra, a medic and healer. Bengali, a martial arts specialist. Lynx-O, a blind wise-man. They also find a younger Snarf name Snarfer.
The Thundercats main villain is an evil being called Mumm-Ra. Mumm-Ra harnesses the power of the Ancient Spirits of Evil to transform him from a frail mummy to an all-powerful being. Mumm-Ra enlists the help of numerous other villains throughout his time battling the Thundercats. Mumm-Ra also employs magic bestowed by the Spirits to trick the Thundercats. Mumm-Ra’s main goal is to obtain The Sword of Omens and the Eye of Thundera embedded in its hilt. Mumm-Ra acquires a sidekick bulldog, Ma-Mutt. Mumm-Ra uses Ma-Mutt to spy and as the focus of many glamors to trick the Thundercats.
