Rimfire is Modo's teenage nephew. The boy idolizes his famous freedom fighting uncle. He's 19 when we first meet him, although we later see him at 16 and even younger. His mother is Modo's sister, and he has a sister of his own --twin, possibly-- named Primer. Rimfire has cream-colored fur and brown hair with an orange/blonde stripe down the middle. In the 2006 series, he has brown fur and the same orange streak through his hair. Having been taught manners by both his grandmother and his uncle, Rimfire is a perfect gentleman, using both "Miss" and "Ma'am" in woman's names (i.e., "Miss Charley Ma'am") In almost every episode he's appeared in, he gets captured.
