After being such a massive success, it's only natural that we'll eventually get a sequel to the quirky strategy game about Abraham Lincoln forming a team of characters from classical literature to fight against Lovecraftian aliens. But the question is, since we already have representation from The Red Badge of Courage, Moby Dick, The Wizard of Oz, Peter Pan, Mark Twain, and many others, what other public-domain folk heroes could they possibly add to the cast?
Each character would need to have a primary weapon modeled after a type of animal, and a powerful special ability that can only be used once per battle. With that in mind, I've already got a few ideas:
*Paul Bunyan: Minigun shaped like his blue ox Babe. Naturally he'd be slow as hell, but capable of taking tons of hits. His Special could consist of chopping down a gigantic tree, which flattens all enemies in a straight line.
*Davy Crockett: Raccoon shotgun named Betsy, like in the old Disney serial. Plus, the part where he killed a bear and brought back its meat to feed starving soldiers could spark a humorous reaction from Robin and Lucina, for whom bear meat is a bit of a recurring gag. His Special would be splitting an enemy in half from 40 yards away by throwing an axe.
*Pecos Bill: Coyote pistol. His Special should definitely be lassoing a tornado.
*Harry Houdini: His weapon would be a tool box shaped like a rabbit that he could use to disable traps, allowing allies to escape from dangerous situations. Going with the stage magician theme, his Special could be sealing an ally and an enemy inside two magic boxes, then throwing knives at the box that the ally was sealed in, only to have them emerge unharmed from the other box while the enemy takes damage from the knives.
*Sherlock Holmes: Bloodhound revolver. Going with the detective theme, his Special would enable him to reveal the locations of all enemies on the map, possibly by seeing through obstacles.
*Mina Harker (Dracula): Like Scarecrow, her weapon is based on a vegetable instead of an animal; in this case, Garlic, to go with the vampire theme. Serves as a counterpart to Randolph Carter in that her Garlic launcher would cause enemies to be repelled away from the shots instead of drawn to them. Her Special is to call forth the morning sun, causing enemies caught in the attack radius to crumble into dust.
*Lampwick (Pinocchio): Has not fully reverted from his donkey form, but is still capable of walking upright and wielding a submachine gun, which is also shaped like a donkey. For his Special, he launches a giant cue ball at a set of equally-giant billiard balls, causing them to ricochet around the battlefield damaging enemies and allies alike, which ties into the original moral about the dangers of gambling.
Naturally, there'd also be amiibo support for all the Fire Emblem characters that came out after Sm4sh, which, in addition to their own primary weapons, also have unique sub-weapons that can't be swapped out:
*Roy: The Binding Blade can send out flaming shockwaves like Ike's Ragnell, and his sub-weapon is a thrown Javelin from his father Eliwood. His Special is a fully-charged Flare Blade from Smash Bros., creating a massive explosion around him and also damaging himself.
*Corrin: The Omega Yato causes their limbs to transform into dragon appendages when landing a killing blow, causing them to penetrate through the enemy and hit additional enemies at once. Useful for enemies that gather in large clusters. Their sub-weapon differs depending on whether the male or female Corrin amiibo is scanned: either a Hoshidan Snake Spirit Scroll for male, or a Nohrian Lightning Tome for female. Other than looking different, the two sub-weapons behave exactly the same. Their Special has them transform into a dragon and summon a whirlpool.
*Alm: Dracofalchion swings in a large arc that displaces enemies that it doesn't kill. Sub-weapon is the Luna Arc bow that his legendary alt wields in Heroes, which deals about half the damage that a weak-point-strike would've dealt, regardless of where the arrow hits the enemy. Naturally, his Special would be the awesome shield-toss jump-stab that he uses to finish off Duma.
*Celica: Beloved Zofia can easily strike enemy weak points. Sub-weapon is the Ragnarok spell, which lightly damages herself each time it's used. Special is summoning the spirit of Mila to restore HP and steam to herself and nearby allies.
*Chrom: Falchion behaves exactly like Marth's version. Sub-weapon is the Randgr(norse symbols)r bow that his legendary alt wields in Heroes, which functions exactly like Lucina's Nidhogg. Fitting how his Smash moveset is a composite of Roy's and Ike's, his S.T.E.A.M. moveset is a composite of his daughter and his ancestor. Special is Awakening Aether, which deals increased damage based on how much health his allies have remaining, representing his famous quote, "Our bonds give me strength!"
*Tiki: Since her Warriors moveset revolving around a purposely-overpowered super-mode wouldn't work right in a turn-based setting, she could simply remain in human form and briefly transform into a dragon for her Special. Primary weapon is blowing fire breath at enemies; sub-weapon is swinging around her Dragonstone like a dagger, similar to her Dragalia Lost counterpart. Both of these weapons are much weaker than average, but to compensate, she's the only character that can use her Special more than once per battle. However, she can only activate it when her steam gauge is completely full, and each time she uses it, it will gradually grow weaker.
*Byleth: Sword of the Creator can hit foes from three tiles away. Sub-weapon to be determined once we get more details on whether they're getting an amiibo for both genders like Corrin. Special is performing Ruptured Heaven on an AOE that resembles the Gambit used by Jeralt's Mercenaries.
