Cupid is a name given to someone who works as a "cupid" for the other reindeer. He is one of Santa's reindeers. Cupid was one of the reindeers that made fun of Rudolph but then praised Rudolph for his red shiny nose. He is named after the Greek God of Love, Cupid. He now likes Rudolph and all of the other reindeers so he is very nice now!
