Copper

Copper is a red-brown, glossy furred, plump tom with green eyes.

Copper and Nightpaw meet one another and connect rather quickly. They eventually admit to loving one another and that they could be mates if not for Nightfall's desire never to become pregnant. Copper's housefolk adopt a new cat, Terra, and Copper becomes her mate. Copper stops Nightpaw and Terra from fighting, as Terra, being controlling, had attacked Nightpaw. Nightpaw and Copper eventually drift out of contact until they meet one another again when Copper is invited to the planning meeting where he helps contribute to how to eliminate the Prophecy Kits, whom he believes are his and Nightfall's.
