Donner's name means thunder, and this reindeer is not someone to mess with. Just like his son Rudolph, Donner was very shy and unsure of himself as a young reindeer, but with lots of hard work he went on to become one of Santa’s strongest fliers.

Donner is known for his kind heart and beautiful singing voice. He's the one who wrote the lyrics for "Rudolph, the Red-Nosed Reindeer"!
