Rudolph the Red-Nosed Reindeer is a legendary reindeer, created by Robert Lewis May, usually depicted as a young fawn who barely has antlers, with a glowing red nose, popularly known as "Santa's ninth reindeer." When depicted, he is the lead reindeer pulling Santa's sleigh on Christmas Eve. The luminosity of his nose is so great that it illuminates the team's path through inclement winter weather.
Robert Lewis May originally intended Rudolph the Red nosed reindeer to be the leader of 7 reindeer instead of the ninth reindeer.
