Biography
Tommy, along with Timmy, run numerous shops assigned by Tom Nook. By the time of Animal Crossing: New Leaf, the two do not need Tom Nook's help to run a shop.

In Animal Crossing: New Horizons, Tommy is a flag-bearer around the island before the building of Nook's Cranny, where he moves in.

The reason why Tommy is Chiaki Sakura Rose's favorite over Timmy is because of an inside joke involving Photopia and the Timmy & Tommy Amiibo. When scanned, the Amiibo can only bring one of them to Photopia, and Chiaki chose Tommy. Since then, Chiaki has sent Tommy Posters to random people with the text "Tommy Poster Tommy Poster" following.
