When Harvest Season begins on his planet, he has an urgent need to return, lest the more monstrous portions of his species' ancestry pop up and cause him to wreak havoc. This frenzied state is useful for harvesting the crops.
Buzz Lightyear of Star Command: The Adventure Begins
Booster is introduced as a janitor that Buzz saves from being fired. Booster is eager to become a space ranger, but so far, hasn't gotten the opportunity. At one point, he overhears the other rangers talking, but when he asks what is going on, he is told simply that it is ranger business, and so he leaves, depressed.
Booster later meets XR, who was led to Booster by the Little Green Men. XR offers Booster a "VIP Tour" of Buzz's spacecraft, and while role-playing, become stowaways. Buzz has taken his spacecraft and is pursuing Mira Nova, who is attempting to bypass Emperor Zurg's defenses. Buzz discovers Booster and XR, and is about to fire Booster, when they learn that Zurg has used the Uni-Mind, a sphere that telepathically links the LGMs, to mind control all of Star Command.
Buzz goes off alone to confront Zurg, but Booster, XR, and Mira follow him, and rescue him. They confront Zurg, but Zurg is able to flee using an escape pod. However, Booster and XR are able to capture Warp Darkmatter, Zurg's accomplice. Due to his role in the rescue, Booster is made a space ranger, and is recognized alongside Buzz and the others for their heroism. Booster then joins "Team Lightyear" a team made up of himself, Buzz, Mira, and XR.
