Rudolph is one of Santa's reindeer who only appeared in A Doomed Christmas. He was the second reindeer to be interrogated by Bird Brain, so that he could figure out how Rudolph and the other reindeer fly. He is voiced by Grey DeLisle.
- His name was never mentioned in the episode, but it is shown in the end credits.
- When Rudolph was first shown, his nose didn't appear red. When he was shown to be freed, his nose finally appeared red.
