Copper

Copper (おまわりさんA, Omawarisan, Policeman A / もんばんさんB, Monban-san B, Mr. Gatekeeper B) is a dog who appears in all the games along with his working partner, Booker. Copper's name comes from the slang term for police officer, "copper." He strongly resembles Japan's national breed, the Akita. In all four games, Copper's dedication to professionalism and his work is in sharp contrast with Booker's doddering incompetence. Copper also prides early risers and warns the player to be careful when wandering around at night. Copper cannot tell the player about the lost and found, but he can tell him or her and type in friend codes with him. The player can visit other people's towns only by using WiiConnect24 or Nintendo WFC.

Copper displays extreme dedication to his job, sacrificing his own desires in order to fulfill his duties.

Animal Forest and Animal Crossing
In, Copper works at the Police Station where he alerts the player of upcoming events, the location of visitors in the town, hosts morning workout regimes in the summer and gives the player's friends a map of the town. Copper marks the player's attendance to morning exercises, and a reward is given if the player participates for a certain number of days.

Animal Crossing: Wild World and Animal Crossing: City Folk
In Wild World and City Folk, Copper has the same job, opening or closing the Town Gate for the player's friends to come through and play. Copper will explain everything that the player needs to know about visiting or inviting a friend. He is on the right side of the Town Gate. On the left is Booker. Copper will give the player their friend code, so they can exchange it with their friends. Copper is much more brave and daring than his partner, Booker, and mocks Booker in his shyness. He also helps with the DS Suitcase.

Super Smash Bros. Brawl
In Brawl, Copper can sometimes be seen in the background of the Smashville stage. Copper also appears alongside Booker as a trophy and a sticker in this game as part of the Animal Crossing series.
