Owned by Kana. One of Hamtaro's best friends in the series, he has the biggest appetites of the Ham-Hams, and also has a crush on Pepper. Oxnard is frightened easily and loves to eat. He often carries around his special sunflower seed.

He has a talent for tarot card reading, which soon attracts the girls, much to the dismay of the other boys. Most of the time, Oxnard's predictions come true, especially for Boss (and usually end in Boss getting hurt in some way).

In the original Japanese version, his name is Koushi.
