XR
(voiced by Larry Miller)

The LGMs, Star Command's resident scientific geniuses, designed and built XR to be Buzz Lightyear's replacement partner. His computer chip brain will observe and mimic Buzz Lightyear's every move. He'll be learning from the best! Buzz remains adamant that any partner would be in too much danger, but the LGMs counter that no matter what happens, they can rebuild XR. The one thing they didn't count on was Zurg's theft of the Uni-mind. Without the Uni-mind, the LGMs can't function. Poor XR has been blasted to bits by Agent Z, and the geniuses that built him now have no idea what they are doing. Their bizarre and haphazard repair of XR results in a robot with a whole new attitude. Once a technological wonder, XR now seems like a reject ranger. But when the micro-chips are down, XR will come through to help save the day.

COMMANDER NEBULA
(voiced by Adam Carolla)

Commander Nebula is the gruff chief of Star Command. He calls the shots. No questions asked. He's tough and demanding, expecting nothing but the best from his rangers. And the one ranger who never disappoints him is Buzz Lightyear. That is, until Buzz vowed to never take on a new partner. Nebula knows that the battle against Zurg is too dangerous for any space ranger to go it alone. You need back up, even if your name is Buzz Lightyear.

AGENT Z
(voiced by Diedrich Bader)

Agent Z is the Evil Emperor Zurg's newest henchman. A mysterious figure, Agent Z wears a helmet that distorts his voice and sinister battle armor. Perhaps most chilling is his robotic arm. His clawed, robotic hand can transform into a ray gun...a flame thrower...and who knows what other evil weapon. A deadly and dangerous fighter, Agent Z's greatest weapon is his ability to anticipate Buzz's every move. That menacing helmet hides a secret. A secret that will shock Buzz Lightyear.

LGM's (LITTLE GREEN MEN)
(voiced by Patrick Warburton)

These lovable, three-eyed aliens are the glue that holds the Star Command space station together. They design and build everything the space rangers need. Thanks to the Uni-mind, a mystical orb hidden on their home world, the LGMs are all mentally linked to one another. They think, feel and act as one. This mental link is the focus of Zurg's evil attention, and it makes the Uni-mind the key to his most nefarious scheme yet to control the universe.
