Buzz Lightyear of Star Command: The Adventure Begins

Buzz Lightyear and Warp Darkmatter infiltrate a hidden lab belonging to Emperor Zurg in search of missing Little Green Men. They locate the L.G.M., free them, and attempt to escape as Zurg's defenses collapse. Zurg triggers a self-destruct sequence, forcing Warp to shield Buzz; Warp is apparently killed in the explosion.

Disoriented by Warp's apparent death, Buzz is consumed by survivor's guilt and vows never to partner with anyone again. He isolates himself from future missions, hoping to honor Warp's sacrifice by flying solo.

Commander Nebula introduces Buzz to Mira Nova, a prodigy ranger from the planet Tangea who can phase through objects with her ghosting power. Nebula intends Mira as Buzz's new partner, but Buzz refuses to team up again.

Buzz intervenes to protect Booster, a well-meaning janitor who dreams of becoming a space ranger, preventing his dismissal. Booster's courage earns him a chance to prove himself on future missions.

In Zurg's fortress, the robotic Agent Z is hired. Zurg learns of the Uni-Mind, a large orb on the L.G.M. homeworld connected telepathically, and he sends Agent Z to capture it.

The L.G.M. on Star Command build XR, a new robot soldier designed to be repaired after any damage. They offer XR as Buzz's new partner, but Buzz remains hesitant, still yearning to work alone. This makes him wary of trusting a new ally.

The L.G.M. receive a telepathic alert about Zurg's assault on their homeworld. Buzz and XR travel to the L.G.M. planet to respond, only to confront Agent Z, who destroys XR and Zurg steals the Uni-Mind.

The L.G.M. rebuild XR, accidentally giving him self-awareness. Commander Nebula orders a full-scale assault on Planet Z, despite Mira arguing that a solo ranger with the Alpha-One could handle Zurg.

Zurg corrupts the Uni-Mind and installs it into the Mega-Ray to bend the galaxy to his will. Mira steals the Alpha-One prototype to fight Zurg.

Buzz pursues Mira in his own craft, unaware Booster and XR have stowed away. He catches Mira and stores Alpha-One in the cargo bay; Booster and XR are then discovered.

Zurg's Mega-Ray subverts several planets and then targets Star Command. Buzz, Mira, Booster, and XR realize Star Command has been compromised and flee aboard Buzz's Star Cruiser. Zurg detonates a bomb on Buzz's ship; they escape in the Alpha-One just before the explosion, and Zurg believes Buzz is dead.

Booster accidentally causes their ship to crash on Planet Z. Buzz insists on finishing the mission alone, leaving the others behind. He fights Agent Z, but is captured and delivered to Zurg.

Agent Z reveals himself to be Warp, who had faked his death and had been working for Zurg as a double agent for years. Buzz dictates a final log entry, a coded distress call to Mira, Booster, and XR.

Zurg plans to use Mega-Ray on Buzz, but XR and Booster intervene to rescue him as it fires. Booster destroys Warp's mechanical arm, and Mira uses ghosting to push Buzz to the Uni-Mind core, restoring it and freeing the suborned peoples. Zurg is left momentarily helpless.

Warp is imprisoned; Buzz admits he cannot work alone and forms Team Lightyear with XR, Mira, and Booster.
