Copper is a guard dog. He has had major roles in all three of the Animal Crossing games. Booker Copper's complete opposite, has always been his partner. His name comes from the word 'cop'.
Copper is dedicated to his work and he is very professional. He is confident with his ability to get the job done and has very high standards that he has set for himself. One thing that is important is that he is always looking out for everyone else, as well. At night he warns players to be careful and when you talk to him early in the morning he will pride you with a compliment.
Copper wears matching outfits with Booker. He has on a dark green helmet that makes his ears protrude out of it and along with that he also wears a red uniform with an X going across it. He wears a brown belt with a rectangular buckle and carries his staff which he confidently holds and he stands lean and straight.
