Ranked from 10 - 1, least wanted to most wanted. pretty much anything after 6 i struggled to think of, so i support them, but not too much. Honourable mention to Issac from golden sun and Geno.
Number 10: Chrom (Fire emblem Awakening)
Awakening got me into fire emblem, and Chrom is cool. Lucina and Robin are already in so there isn't much of a desire there for him, but if anyone gets in from FE it's probably him, which will be cool. Hope he's a Roy echo though, not an Ike.
Number 9: Funky Kong (Donkey Kong series)
He's cool. Like him more than any other potential DK characters. Don't want a unique fighter out of him but a DK Echo would be nice.
Number 8: Midbus (Mario and Luigi Series)
Midbus was a cool guy in the M&L Series. Literally, since he had ice powers
. I saw he'd work well as a Bowser echo, just give him ice breath instead of fire.
Number 7: Birdo (Mario series)
Yoshi echo. Birdo has always been awesome and she needs more recognition. The return of the SMB2 stage from melee kinda dashed her chances but that's why this is a wish list!
Number 6: Amaterasu (Okami)
Wolves are cool. Ammy is cool. Amazing potential for a unique fighting style and some cool okami tracks. Okami is getting remade for the switch and had a Wii port + DS sequel so she has a chance! Cmon ammy!
Number 5: Hector/The Black Knight (Fire emblem/Fire emblem: Path of radiance/Radiant Dawn)
Ike Echo's. Hector because Hector is cool. The black Knight because the black knight is cool. One of the best Villains FE has had. I don't really mind which get in but I would like either!
Number 4: Gardevoir (Pokemon series)
One of my favourite Pokemon ever. Doesn't make my top 3 despite that. (Though every pokemon after my top 3 change depending on the day). Super popular, was in pokken, got a mega and a fairy type. If she's in I expect a Mewtwo or Zelda echo.
Number 3: Micaiah (Fire emblem: Radiant Dawn)
It's not happening. But she was one of the best characters in radiant dawn and is really cool. Would like a 100 % Mage fighting style which I think she could bring.
Number 2: Skull Kid (Legend of Zelda: Majora's Mask)
From the best Zelda game. More Majora's Mask representation! Also Majora's mask was a cool villain and we need more villains and dark magic,
Number 1: Bandana Waddle Dee (Kirby Series)
Cute, Round, brave, and has a spear. Spear ability in Kirby was always one of my favourites and fighting styles with weapons that are not swords is something smash desperately needs. I really hope he's in. I think a spear based moveset would be so fun and interesting! Plus we need to round out the quartet of Kirby characters!
