Copper (おまわりさんA・もんばんさんB,Omawari-san A; Monban-san B?, Policeman A; Gatekeeper B) is a dog who appears in every game in the Animal Crossing series along with his working partner, Booker.
His name comes from the slang term "Copper", meaning "policeman". In all of the 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 is in charge of opening and closing the Town Gate to allow other players to visit using WiiConnect24 or Nintendo WFC. He and Booker are shown to wield wooden pikes which shows that Tortimer has quite possibly permitted them to use, if necessary, non-lethal force.
Copper works diligently, being straightforward with his job, in contrast to Booker.
In Animal Crossing and Animal Forest e+
In Animal Crossing, 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 your 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.
In Wild World and 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. Copper will explain everything that is 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 unique friend code, which can be exchanged with friends. Copper is much more brave and daring than his partner, Booker, and mocks him in his shyness. He also helps with the DS Suitcase and Wi-Fi.
When a villager gives the player an invitation to Crazy Redd's, they warn them not to show it to Copper, even though when the player does, nothing happens. If the player tries to sell it at Tom Nook's Store, Tom will be offended and will say he will NOT buy it, but will take it off of their hands.
In New Leaf
Copper returns in New Leaf alongside his companion Booker. Both return to their previous roles as police officers who can be found in the Police Station. He only appears in the game if the Modern Police Station is built.
Super Smash Bros. Brawl
In Super Smash Bros. Brawl, Copper can sometimes be seen in the background of the Smashville stage. Copper also appears as a trophy and a sticker in this game as part of the Animal Crossing series. The trophy has him and Booker standing on it and reads:
"The guards stationed at the town gate through which travelers come and go. Copper, who's on the right, is in charge of traveling via Nintendo WFC, and Booker on the left runs the lost and found. Booker's a cute fellow who's known for his indecisive manner...maybe. Copper's diligent, dedicated, and always ready to lend a helping paw."
Copper is a stand-up citizen, and one of the hardest-working animals you'll ever meet. You think rain or darkness keeps this top dog from his duty? Not a chance. He even says that umbrellas are for cadets!
