No games other games on Switch (or Switch 2) feature Dark Samus, Dark Pit, Wii Fit Trainer, or Kazuya. Only Super Smash Bros Ultimate.
Admittedly I'm being generous with the word "appears", Duck Hunt and R.O.B. only appear on Switch through microgames in WarioWare GBA, and Lucas only appears in Japan. Counting alternate skins, the hero of Dragon Quest VIII also appears nowhere, although you can dress up as him in XI and VII Reimagined.
Again I just thought this was interesting and wanted to share it. Hopefully this isn't misinformation.
