Description:  The Dino-Riders cartoon is about the battle between two futuristic alien races, the heroic Valorians and the evil Rulons, who both get transported to prehistoric Earth. The Valorians befriend dinosaurs telepathically and ride them into battle, while the Rulons use a brain-washing technology to control and arm dinosaurs against their will. The series, which was based on the Tyco toy line, consists of 14 episodes and focuses on the conflict between the two sides.

The conflict: The Valorians and Rulons are locked in a war that forces them to flee their home planet using a time travel device. They both crash-land on prehistoric Earth, where they continue their fight, but now with dinosaurs as their primary allies and weapons. The sides:

Valorians: A peaceful, telepathic, superhuman race that befriends and unites with dinosaurs.

Rulons: A group of aggressive, humanoid-animal aliens led by the warlord Krulos. They use technology to brainwash dinosaurs into becoming unwilling soldiers, often attaching laser cannons and other weapons to them.

The premise: The core of the story is the classic good vs. evil battle, with the Valorians fighting to protect Earth's dinosaurs from the Rulons' control. The Valorians ultimately become known as the "Dino-Riders" as they form a bond with the prehistoric creatures to fight back against their oppressors.
