On the assumption spirits, DLC Mii Costumes, and assist trophies still deconfirm: Doomguy*, Scorpion, Lara Croft*, Spyro*, Crash, Hollow Knight or Wasp*, Hat Kid*, Toriel*, Monster Hunter*, Dark Souls, Tekken old man, Master Hand, and Okami Amaterasu* are cool third-parties off the top of my head.
For first parties: Sylux from Metroid, Adeline from Kirby*, Zelda rep but idk who, DK rep but idk who's left (Dixie, Cranky, and Funky are all Spirits, would have loved any of them), Star Fox is dead RIP, no more Pokemon please, really drained first party options with spirits...
*Top picks, but I've been saying the roster is perfect since they added Ridley and K. Rool. Then they added Banjo-Kazooie. Anyone else is a bonus. <3
