For: Would have previously been considered a long-shot, but the Fighter Pass era and the release of all 4 main games on Switch shortens the odds. A fun, much loved character that has spin moves and agility on his side.
Against: Nintendo has zero record of collaborating with publisher Activision on the Smash Bros. series and he's a PlayStation icon historically, so...
Final Smash: Opponents get trapped in one spot as Crash jogs towards them, strange grin on his face, before spinning them off in a whirr of arms and legs.
Edelgard, Dimitri and Claude
Notable game(s): Fire Emblem: Three Houses
For: Could be unique in the lineup as a three-house echo-fest combining the power and personalities of the Black Eagles, Blue Lions and Golden Deer into a supergroup; Battle experience up the wazoo; Not enough FE characters in Smash...
Against: Jokes! Fire Emblem already had plenty of representation, and with the addition of Byleth we're up to our ears in the Fire Emblems.
Final Smash: Black, Blue and Gold combine into a muddy brown of incredible HP drainage.
Notable game(s): Pokémon Sword and Shield
For: Would prove correct the whispers and theories online following the pattern of Gen 6's Water starter (Greninja) and Gen 7's Fire type (Incineroar); Big ape with a drum = ace.
Against: Nothing really, except there are plenty of Pokémon already.
Final Smash: Drum Beating is a no-brainer. It's super effective.
Notable game(s): the Kingdom Hearts series
For: Hugely popular; Keyblade could offer plenty of weapon variety; All sorts of potential for Disney(!) support character cameos; Some company for Cloud.
Against: Any Disney crossover elements seem unlikely.
Final Smash: Sora sits down and threatens to explain the entire Kingdom Hearts story and associated lore. All other combatants dive off the stage.
Notable game(s): No More Heroes, No More Heroes series
For: A stylish addition to the roster; the recent release of No More Heroes 3 has only boosted his profile.
Against: An assassin's beam katana, however cool, is still a sword, and there's arguably more than enough sword fighters already.
Final Smash: A toilet appears and Travis sits down. All opponents vacate the stage in disgust.
For: Handy in combat; Melee skills a-plenty; Could do with a change of scenery.
Against: Possibly the least family-friendly contender on this list.
Final Smash: The Doom Slayer removes his helmet to reveal a bloody, pixelated grin. A Cacodemon appears and smashes your opponent off the stage before Doomguy cracks out the BFG and sends it back to Hell.
Cuphead / Mugman
Notable game(s): Cuphead
For: Oozing '20s/'30s animated style; Would make for an incredible stage.
Against: Limited run-and-gun moveset; Already a Mii costume.
Final Smash: A huge happy sun appears in the background and comes to say hello. All opponents are obliterated. Sun is sad.
Notable game(s): Paper Mario, Paper Mario series
For: We've already got Paper Mario stages; Paper Luigi echo fighter; He came to Switch in Paper Mario: The Origami King, so that would add some nice cross-game promo synergy, no?
Against: Nothing obvious. Meh-meh-Mario?
Final Smash: Kersti the sticker fairy turns up and turns your opponent into a sticker which Mario then picks at. Unfortunately, it doesn't come off cleanly so you roll it into a ball and flick it into oblivion.
Notable game(s): Tomb Raider, the Tomb Raider series
For: Iconic character with PlayStation roots; Handy with a range of weapons; Would add to the ranks of female fighters.
Against: What Lara would we really want to see? Old-school, polygonal PS1-era or the more modern, rugged (and anatomically realistic) rendition?
Final Smash: A comically polygonal T-Rex appears and wreaks havoc.
Akira Howard and Legion
Notable game(s): Astral Chain
For: The dynamic between the Neuron officer and their Legion partner could create interesting possibilities; who could resist a PlatinumGames partner-up with Bayonetta.
Against: None that jump out at us.
Final Smash: Lappy, the yellow dog and police mascot, appears and opens a sizeable can of whoop-ass.
Notable game(s): Rayman Legends, the Rayman series
For: Platforming hero; Unique anatomical arrangement; Ubisoft and Ninty sitting in a tree...
Against: Despite some exceptional games to his name, will Rayman ever stop feeling... a bit weird?
Final Smash: Rayman and his opponent approach each other - the enemy throws a flurry of punches, but they pass through the gaps between appendages. Rayman cackles maniacally and dragon punches his rival into the sky.
Notable game(s): Various
For: Apparently Waluigi is quite a requested character; Smash hasn't filled its quota of wiry moustachioed fighters; Purple is the best colour.
Against: People will never be satisfied and someone somewhere will still complain about it.
Final Smash: Sakurai himself appears in-game. Everyone else dies of shock. Sakurai drops mic. Game crashes. Done.
