Dino-Riders (1988)

Llahd's attempt to show his worth to the Dino-Riders in battle nearly costs him and Tagg their lives. He runs away to prove that he can be a hero all by himself, but can't help a trapped herd of Torosauruses alone. Meanwhile, the camp is left at half strength while his people go out in search of him. The Rulons take advantage of the ship's vulnerability and launch an attack that the Dino-Riders cannot overcome without reinforcements.
