- "To infinity, and beyond!"
- ―Buzz Lightyear
Captain Buzz Lightyear is a Human space ranger, a member of the elite Universe Protection Unity of the Space Rangers Corps and one of the most respected agents in Star Command. His major responsibility is to protect the galaxy from the Evil Emperor Zurg, sworn enemy of the Galactic Alliance. Despite being his nemesis, Zurg has also claimed to be Buzz's father on more than one occasion, but later denied his own statement, explaining that he was just trying to trick Buzz.
Captain Lightyear is well known for his bravery and commitment to his duties, although he has learned to become less serious and to relax and have fun during free time. After Buzz's former partner, Warp Darkmatter, turned out to be an evil spy working for Zurg, Buzz became the leader of Team Lightyear, which also includes the Tangean Mira Nova, former Star Command janitor Booster Sinclair, and the robot XR, created by the Little Green Men.
- A Buzz Lightyear action figure is one of the main characters in the Toy Story movies franchise.
- In the first movie, Buzz does a Vulcan salute to Sheriff Woody, but he says "Farewell" instead of the more classic "Live long and prosper". He does the same when saying goodbye to the other Buzz in the second movie.
- Buzz's spaceship is named 42, likely a homage to The Hitchhiker's Guide to the Galaxy.
- In 2008, a real Buzz Lightyear toy was sent to space by NASA and spent six months in the International Space Station.
