Buzz Lightyear is one of the main characters in Toy Story and Toy Story 2. In the first movie, Andy recieved him for his birthday and quickly became his favorite toy, though Buzz believed himself to be the real Buzz Lightyear. This caused tension with Woody, who was Andy's favorite toy before he arrived. Out of jealousy Woody pushed him out of Andy's window, and they both ended up in Sid's house, where Buzz discovered he was a toy. Putting all differences aside, Buzz and Woody worked together to escape Sid's house and became best friends. In the sequel, Buzz is the leader of the rescue party that goes to save Woody from Al.
