Standard Special - Item Grab: Yanks items right out of other fighter's hands, including Smash Balls (which just resume floating around) and Dragoon pieces (which scatter)
Other moves can be nips/bites, flap his wings to send an air current, a reflector like Mario's Cape where when he honks it repels items or spins a close enemy around
Have his attacks be similar to Peach where she grabs veggies to throw (he grabs random items he stole) and his forward Smash has him hit you with random items (bat, a No Goose sign, a hairbrush)
LOTS of grabs, obviously.
Final Smash he reigns on high with his crown and rings the shit out of this bell, damaging and putting into stun all in the area
Really surprised we haven't seen a Resident Evil rep with all the re-releases of RE0 through like 6 on the Switch. Though it may feel like a Snake clone unless they use Super-Wesker...
Geralt from Witcher III would make a good tanky Sword/Magic fighter. But I'd rather no more humans with swords until other options are explored. Also Alucard from Symphony of the Night, but same reason.
Still shocked we don't have Zero from Mega Man... They're making the Zero collection, sooo maybe?
I wouldn't be surprised to see an Undertale character. I still know nothing about the game, but they put a song in and the creators seem to want a rep in.
