Buddy was born to Susan Wells and Walter Hobbs. She put him up for adoption after he was born due to a unexpected pregnancy. Walter never knew he existed. Susan soon died and baby Buddy was in a orphanage (for a year) for a little while.
One Christmas Eve, baby Buddy witnessed Santa Claus coming down the chimney and eating cookies. Buddy spotted a teddy bear and crawled into Santa's sack. At the North Pole he crawled out and surprised Santa and the elves. Papa Elf took him and raised him as his own child. He grew up an elf.
Buddy found out as an adult that he was human. He wanders all over New York City until he finds Walter, finding out that he had remarried and has a son named Michael. Buddy is happy until Walter disowns him after he accidentally ruins an important meeting at his office. He runs away and hides in Central Park. He meets Santa who is trying to fix his sleigh. Buddy fixes it and saves Christmas.
Eventually, Buddy marries his sweetheart, Jovie, and they have a daughter named Susie. They visit the North Pole often. Both Buddy and Walter wrote a book together about the former's adventures, titled Elf.
- Will Ferrell, the actor who played Buddy, caused several minor traffic accidents when walking through the Lincoln Tunnel in his costume because people were so surprised to see him wearing an elf outfit.
- Will Ferrell suffered from headaches throughout filming, as he had to actually eat all of the sugar-packed food in the elf food pyramid on camera.
- His real first name is the same as his actor.
