XL

XL was originally a good guy for Star Command, but due to his violent and destructive personality he turned to the dark side.

XR's predecessor (and technically older brother), who was shut down due to his villainous attitude. When he was reactivated by Emperor Zurg, XL rebuilt himself into a larger, more powerful robot with cutting edge (and stolen) robot parts. His head is red, whereas XR's is yellow. He infiltrates Star Command numerous times because its command codes are in his head. Like XR, he considers Commander Nebula his father, though he resents him for shutting him down. He later redeems himself and is converted into an office managing robot capable of photocopying, collating, and other office related functions. His name is a pun referring to his size (extra large).

In the episode: Revenge Of The Monsters, he helped Buzz Lightyear and his younger brother XR to stop NOS-4-A2 from infecting everyone else into wirewolves. Then he was back in Star Command as a copying machine and he joined the Star Command staff.
