Donder was the first girl reindeer to graduate from the prestigious Roe Military Academy, and as far as she's concerned, boot camp never ended.

In fact, she has the other reindeer on Santa's team practicing constantly year round so they stay in shape for "The Big Night".

The only reindeer that doesn't play in her reindeer games is Dasher (because he's always on vacation!), and quite a rivalry has developed between the two.

Donder believes, and rightly so, that she should be Santa's Reindeer Captain and not Dasher! This rivalry however is one of good spirits between two professionals and no accidents or anything bad has come of it yet.

The other reindeer respect and appreciate Donder's workout routines and maneuver exercises even though their little legs and hooves get quite sore from them.
