Mario Series:
1:Mario (Alt Costume for Dr.Mario)
2:Luigi
3: Peach (New Neutral-B that references Super Princess Peach, Daisy Alt)
4:Bowser (Alt Costume for Dry Bowser)
5:Bowser.Jr* (The Koopalings return)
6: Rosalina (Maybe a new Side-B)
7: Captian Toad (Can barely jump and is somewhat slow, but is rather powerful. May be replaced by a more equal regular Toad if we don't get another game to keep Captian Toad relevant. Alt for Captian Toadette.
DK:
8: Donkey Kong
9: Diddy Kong
10: Either K.Rool or Dixie* (Don't care either way. Probably Dixie.)
Wario:
11: Wario (Alt for Mario Style.)
Yoshi:
12: Yoshi (Final Smash Changed to the Eggdozer from New Island, Orange, White, and Yarn Yoshi as alts)
13: Kamek* (Only other Yoshi rep I could see coming. Largely projectile-based, with good recovery.
Zelda:
14: Link (Redesigned as BoTW style, Remote Bomb as new Down-B.)
15: Zelda (Redesigned as BOTW style)
16: Sheik* (Reverted to OoT style, due to representing that game)
17: Ganondorf* (Overhauled to have moves from Zelda. Demise as alt.)
18: Toon Link* (Young Link alt)
Kirby:
19: Kirby (Final Smash changed to the Hypernova from Triple Deluxe)
20: Dedede (Masked Dedede alt)
21: Meta Knight*
22: Bandana Dee ( Slightly heavier and only has 1 midair jump compared to regular Kirby. Attacks have a long range. His Final Smash is a modified version of Dedede's from SSBB.
Metroid:
23: Samus
24: ZSS*
Star Fox:
25:Fox
26: Falco*
27: Wolf*
Pokémon:
28: Pikachu (Raichu alt)
29: Charizard
30: Jigglypuff*(Igglybuff alt)
31: Mewtwo*
32: Lucario
33:Greninja*
34: Decidueye (Highly Projectile based, a little slow and has large (and 4) Jumps. If Gen 8 releases prior to Smash 5, this will be a Gen 8 Pokémon instead)
35: Grovyle* (Represenitive of the Spinoffs, mostly PMD. Rather fast, but a little bit weak on offence. Final Smash stops/slows time for everything exept for you. The only character on the list I put on via bias.)
Earthbound:
36: Ness* (Ninten alt)
37: Lucas (Claus Alt, PK Starstorm acts like how it did in Brawl.)
F-Zero:
38: Captian Falcon
39: Blood Falcon* (Has Ganondorf's old moveset)
Fire Emblem:
40: Marth (Lucina alt)
41: Ike
42: Roy*
43:Robin
44:Corrin*
45: Whoever the new FE Character is.
Kid Icarus:
47: Pit
48: Palutena*
49: Dark Pit* ("Why remove Dr.Mario and Lucina and leave Dark Pit?" You might say. My answer is he can be de-cloned easier than the other 2. Give him other things from Uprising or give him Pit's Stuff from Brawl, and he's now in Wolf territory. Plus, Sakurai probably wouldn't hinder his own series.)
