David is a strategic fighter, but always puts his friends ahead of himself. He has light brown hair and sky blue eyes. His Digimon, Dorumon, is a bit of a wild card with a personality like a tornado; calm one minute, bouncing off the walls the next. Dorumon's Digivolution line is his "data" path- his champion form is Dorugamon.
Dorumon is relatively powerful, and in his champion form took down a Garurumon that had attacked for no known reason.
David's best friend is Kiryu, his brother.
