Team Lightyear is a group that worked for Star Command in Buzz Lightyear's Universe. They are the main heroes of the series Buzz Lightyear of Star Command and have been battling Emperor Zurg and several other evils and defending their worlds. Because Zurg is a member of Team Nefarious, Team Lightyear and Star Command have become members of the Anti-Team Nefarious Freedom Fighters.
Known as the "pride of Star Command", Buzz Lightyear is the leader of Team Lightyear. He is the only human on the team and is the main enemy of the Evil Emperor Zurg who finds Buzz to be a constant thorn in his side in his plots to rule the galaxy. Buzz is always certain to do the right thing. He even wrote half of the regulations in the Star Command Mission Manual.
Mira Nova is well-known as the princess of Tangea, though she refuses to let her royal status impede her abilities as a Space Ranger. She is the co-pilot on Team Lightyear and second-in-command of Buzz Lightyear. As a Tangean, she is a valuable member for her mental abilities such as ghosting through objects or searching for information in the minds of others.
Originally a janitor on Star Command before becoming part of Team Lightyear, Booster Munchapper is from the planet Jo-Ad and is arguably Buzz's biggest fan. Booster is able to recite the Space Ranger Mission Manual from memory and knows about almost every mission and maneuver Buzz has ever used. He is the caring sort and is proud to be able to help save the day as a Space Ranger.
XR, or the Experimental Ranger, is a robot built by the LGMs for the purpose of being Buzz's partner. He often falls apart, is blown up, or is otherwise destroyed on missions, but fortunately the LGMs designed him to be easily repaired. He is often cracking jokes or flirting with women, though there are times when he will be serious about his job. He occasionally calls Commander Nebula 'father' because he technically was authorized to be built by him as a slip-in for the LGM's vacation request.
