During a Nintendo Direct today, Nintendo announced that Isabelle from Animal Crossing will be a playable fighter in Super Smash Bros. Ultimate.
A teaser for Isabelle featured attacks for Isabelle including a fishing rod, thrown pot, a bucket and more.
Alongside Super Smash Bros. Ultimate’s full debut at E3, Nintendo announced that the game will feature every fighter in franchise history. Since then, Nintendo has revealed additional new characters (and echo fighters, who mimic existing characters’ movesets) including Daisy, Ridley, Simon Belmont and Richter Belmont, King K. Rool, Chrom, and Dark Samus.
