1st party:

.Wolf Link & Midna (Duo Fighter)

3rd Party:

.Scorpion/Sub-Zero(Eco)

.Crash Bandicoot

.Kratos

.Kei (Ape Escape 3)

.Sly Cooper

I also like the idea of changing the moveset of young link for a majoras mask theme

Ganondorf could also change to a TOTK design, summoning the gloom hands in one of his special moves, and calamity ganon as his final smash

The only notable omissions from Nintendo icons IMO are Dixie Kong and Toad. I don't personally care at all about Toad, but it's very weird not having any version of him playable. Dixie Kong I care a lot about. Outside of those, I already feel like everyone I ever wanted to have in Smash is there.

Wouldn't hurt to see another F-Zero character, though...

I mean I made an Article about the figthers I consider overdue for a spot. Most of the ones in that article are ones I would also love to see, but my top choice is far and away Lloyd Irving.

A few others that could be cool

• Ori
• Hornet
• Astral Chain protagonist
• Sans or Kris (from Deltarune)
• Raiden
• Another Persona character (not likely, but there are just so many great ones: Aegis, Akechi, Violet, Makoto etc.)

And I'm a bit on the fence but Maelle from Clair Obscur has potential for a really sick moveset.

I'm still waiting on Shantea, Terra from Final Fantasy VI, because she deserved to be there more than the FF VII reps, and Celica from FE Echoes, because Chrom stole her damn place. Ultimate was the first Smash since Melee that didn't launch without a rep from the latest FE at the time, but instead we got ANOTHER Awakening rep, and the DLC completely skipped over Echoes to the next game in the franchise AND I'M STILL SALTY ABOUT IT.
And Sylux, but don't make him a Samus clone. And declone Dark Samus too.

Captain Toad has his own game, and Toad was the protagonist of Wario's Woods. Not to mention all the times Toad has been playable in platformers and spin-offs.

Representation isn't the only reason a character gets into Super Smash Bros., but Toad has for a long time met that requirement.

I also agree about Dixie. She makes more sense than Cranky or Funky even. 

Blaziken , Bomberman and Shantae is all I care for.

eh...

Shadow the Hedgehog
Kris (Deltarune)
Aigis (Persona 3)
Will (Metaphor: ReFantazio)
Crash Bandicoot
Dante (Devil May Cry; make him as broken as possible to trigger competitive Smash players)
Ganondorf with an actual unique moveset and not a Captain Falcon semiclone

Lara Croft seems to be turning up in a lot of different games these days - why not put her in Smash Bros whilst we're at it?

This is my full wishlist right now. My top 3 are a Zelda newcomer (well overdue, i picked sidon/impa here) Lara Croft because shes iconic and would have a acrobatic moveset probably with guns which only 2 characters use currently. Third is Rayman, wanted him for ages and would be fun with his floating limbs shenanigans.
