Isabelle (しずえ, Shizue) is a major character from the Animal Crossing series. Since her debut in Animal Crossing: New Leaf as the player character's secretary, Isabelle's popularity has resulted in her becoming the de facto mascot of the Animal Crossing series.
Isabelle made her debut in Animal Crossing: New Leaf as the Mayor's eager, although sometimes scatterbrained secretary. Slightly naïve but nonetheless hardworking, Isabelle tries to do anything to please the mayor. Her duties as the mayor's secretary involve aiding the player in signing ordinances into law, making preparations for public works projects, and officiating various ceremonies. On numerous holidays throughout the year she appears in the town plaza, giving out themed items to players who speak with her.
Following her debut, Isabelle's popularity quickly catapulted her into becoming the de facto mascot of the Animal Crossing series, with promotional material featuring her far more prominently than other major characters, such as Tom Nook.
Isabelle appears in several major roles.
As an Assist Trophy
Isabelle stays in place, tossing healing fruit to the player who summoned her. While it is possible for opponents to intercept the fruit, only the summoner has the advantage of only having to touch the fruit to heal; opponents will have to actively grab them with the shield or attack buttons.
While Isabelle cannot be attacked, she will flinch if opponents get close.
If the summoner is KO'd while she is still out, she will hunch over with a dismayed expression until the player returns. Conversely, she will cheer if her summoner scores a KO.
In Smash Tour
Isabelle appears as an item in Smash Tour. When selected, all stat boosting items near the player grow to their maximum size.
As a costume
Isabelle's standard trophy can be obtained in both versions of Super Smash Bros. 4, and in Super Smash Bros. for Wii U it is part of the Animal Crossing: New Leaf Trophy Box. The variation in her sweater outfit is only available in Super Smash Bros. for Nintendo 3DS.

Isabelle appears as a newcomer in Super Smash Bros. Ultimate. She was revealed during the Nintendo Direct on September 13th, 2018 alongside a teaser for the then-unnamed Animal Crossing: New Horizons. Although Isabelle shares several moves with Villager, the overwhelming majority of her respective versions have minute aesthetic and/or mechanical differences. When coupled with her other moves being unique to her, as well as her somewhat different attributes, Isabelle functions as a semi-clone of Villager.
