Maybe they could go the Tatsunoko Vs Capcom route and have the final boss be from a series not represented anywhere else in the game.
Like the Rhombulans, or Monita?

Yep. Pretty sure the AI often accidentally did it themselves, in fact.

🏳️⚧️she/her | Vio Rhyse AlberiaHere's a quick idea list under my parameters (or just for bosses in general, however Sora chooses to implement bosses)
Mario series: Midboss: Hisstocrat (Mario 3D World), final: Dry Bowser (NSMB)
Donkey Kong: Mid: Cap'n Greenbeard (DKCR), final: King K. Rool (natch)
Zelda: Mid: Goht (Majora's Mask), final: Demise (Skyward Sword)
Metroid: Mid: Thardus (Metroid Prime), final: Queen Metroid (as she appeared in Other M)
Yoshi: Mid: Don Bongo (Yoshi's Story), final: Giant Baby Bowser (Yoshi's Island)
Kirby: Mid: Krakko, final: Marx Soul (Super Star)
Star Fox: Mid: Assault Apparoid (Assault), final: Andross
Pokemon: Mid: Regigigas, Final: Darkrai
Just for the 8 biggest franchises.

I'll throw out some bosses from each series I know enough about to actually throw out bosses for, barring Wii Fit and Animal Crossing.
- Mario series: Bowser Jr. in the Junior Clown Car, complete with it's boxing glove arms. Of course, it could do other things, like shoot Bullet Bills or have Junior throw down Bob-ombs. Oh, there's also General Guy. I loved that fight.
- Donkey Kong: Colonel Pluck and the Stompybot 3000. Don't ask why, I really like Colonel Pluck.
- Zelda series: Helmaroc King.
- Metroid: Omega Pirate, RB176 Ferrocrusher. This is the song, written for the train chase...
- Kirby: Grand Doomer, HR-D3.
- Kid Icarus: Great Reaper, Hewdraw Reborn, Phoenix... the list goes on and on, honestly.
- Sonic: Eggman. Duh. (Not sure what mech he'd use, though.)
- Mega Man: Guess who? DOCTOR WILY, THAT'S WHO,
AND I'M COMING AFTER YOU, TOOOf course he'd be in his trademark, teleport-spamming Wily Capsule, and maybe we could even fight a Wily Machine right before! (As far as Wily Machines go, Wily Machine #9 is my favorite.) - Pokemon: I second Regigigas.

🏳️⚧️she/her | Vio Rhyse AlberiaIf Regigigas shows up, I hope he makes the terrifying hellspawn noises he made in the anime.

Animal Crossing's boss?
