Simon: The third party that is the most glaring omission from the current roster and the most easily attainable. Uses the obligatory whip to be a long ranged fighter, with range similar to the Monado. All whip attacks can be angled up or down similar to Marth's new Shield Breaker, and with Whip Smashes, Simon has smashes that reach in all the diagonal directions as well, as well as aerials that can as well. Close combat offers him a sword as a CQC weapon, though it is weak and not ideal as Simon is designed as a zoner. He is also unique in terms of properties: he's lightweight (reflecting how easily he can be knocked back in his games), is slow (weird for a lightweight) and a poor jumper (which, combined with his low speed, gives him some of the slowest movement options in the game). However, his attack speed is rather fast. His most similar competition would be Rosalina in terms of playstyle, only Simon uses a barrage of attacks instead of a puppet to keep the opponent out. The whip's range is about as far as uncharged Luma Shot too, for scale. Specials do not include the whip, but do include throwing knives (Neutral Special: as fast as Needle Storm, but cannot be charged so only one knife is thrown at a time), Holy Water (Down Special: small pillars of flame appear from the ground, traveling away from Simon. The size is about as tall as Elfire.) and the axe (Side Special. Thrown in an arc like Yoshi's Eggs. Designed as an anti-air and deals more damage against airborne opponents). The Up Special is a Whip tether now that we know they're back. The final Smash is the Rosery, which is a quick flash of holy light that instantly kills anyone with more than 100%).
Chorus Kids: The rhythm based fighter. Every attack has two hitboxes, with the option to do a third one via an additional input. The attacks are spaced out rhythmically, so following the beat for the third input is key. Landing the rhythm will result in increased damage and knockback, while missing the beat reduces damage and knockback instead. The importance of setting the beat is why I believe this trio is the best Rhythm Heaven character, as the hits connecting provide audible cues to set the beat for the third attack. This would be opposed to a visual cue for characters like Karate Joe or Wrestler, as well as other Timed Hit characters like Geno or Paper Mario. Like Duck Hunt, all three characters move as one and they follow each other and share percent. This does give them a rather large hitbox horizontally, though it is compensated with low height (their hitbox is Mario's, rotated 90 degrees. The moves are all based on rhythm minigames from the large assortment available in Mega Mix.
Elma: Honestly it could be any Xenoblade character, but I think Elma stands out the most due to Skells. Elma fights in her Skell, which has the entire arsenal of XC2 weapons in it. We're talking guns, lasers, missiles, swords and shields. Like the Clown Car Jr., the Skell takes reduced damage and knockback from attacks, though Elma cannot be damaged herself while piloting the Skell. However, once the Skell takes 100%, the Skell explodes (dealing no damage) and Elma appears and fights on the ground (the percentage is shared between Elma and Skell, and Elma appearing does have a few invulnerable frames like Pokemon Change). In this form, Elma fights with her dual guns and dual swords, giving her both ranged and CQC options, as well as movement options through moves like Sliding Slinger. Basically, think of every moveset you've seen for Elma. This is what that is, but the integration of the Skell gives her something truly different and makes her a Stance-change fighter. Unlike Bowser Jr., she does not take increased damage from hitting her body. The final smash varies depending on form: In the Skell, she'll simply force it to explode. This time, it deals tremendous damage. On foot, she performs Hundred Shells, unleashing a barrage of bullets in front of her.
Nihilego: I think this is the most interesting Pokemon option we have. Nihilego fights by poisoning its foes. Most of its special moves and all fully charged Smashes inflict poison, which is displayed on the HUD. Poison causes damage over time like White Pikmin (in fact, its the same status effect), and lasts 7 seconds unless reapplied. Nihilego's attacks are laughably weak (it only has 53 attack, barely double what Pichu has), but it racks damage up quick thanks to Poison's DoT. Additionally, its moves are much stronger when striking a Poisoned foe. It can spread its poison through Acid Spray (Neutral Special: an arc-shaped poison spray that attacks in-front), Venom Drench (Side Special: a vertical shot of poison, kind of like a laser) and Toxic Spikes (Down Special: lay a toxic trap on stage similar to Banana Peel; can have two at a time; cannot be picked up; If a third is summoned, the oldest vanishes). The recovery is Head Smash, which is a lot like Fire Fox in that it is an angleable recovery with a charge time. This one also deals self-damage to Nihilego. This moveset gives Nihilego the unique status as a debuffer, based around crippling the opponent from all sides so that is can win. Rather fitting for a Parasitic Pokemon if I do say so.
Spring Man: I think we'll be getting something from the early Switch time as the Switch is a big deal. ARMS was developed alongside Smash, and I believe a placeholder for an early Switch character could have been part of the design proposal (which turned into Spring Man). All of Spring Man's moves have a lot of reach to them, obviously. Charging also increases range as well as damage, which fits into ARMS key mechanic of always charging punches. He's also rather average in terms of stats, though after 100%, he no longer has to charge his moves to reach max damage and range; like in ARMS, they are permanently charged to max. Neutral Special is Toaster, a charging move with a fire effect at max range. This range is identical to Jolt Haymaker's range at max charge, though not reversible and does less damage to compensate for the massive range. You can also angle it as it flies. Side Special is Boomerang, with similar range. The caveat is that the fist only goes halfway: the boomerang on the arm is then released to complete the distance, and, like the Links, Spring Man can move around and the boomerang follows him back. The knockback on max-charge is also really high, referencing the wind effect in the original game. Side Special is Tribolt, a stunning three-pronged projectile that leaves his hand immediately (the fist has no hitbox). At max charge, this stuns just like ZSS gun. All other attacks use the Toaster, meaning the fire element is applied on all attacks. Up Special is a Grab, where he grabs the ledge kind of like a tether. However, if he finds the ledge, he goes flying towards it, with himself being a hitbox to prevent any edge guards. The final smash is the Rush ability, which is literally just a barrage of punches. As a final nod to his game and his innate parry ability, Spring Man's perfect shield timings are easier to hit due to a longer duration by a few frames (think Bat Within in terms of a grace period).
Dixie Kong: Diddy with positive multipliers applied to her jump height and speed, and negative multipliers on damage and knockback (the inverse of Dr. Mario). This gives Dixie a mean combo game, with the tradeoff of taking forever to kill. Additionally, she has Diddy's Flying Monkey Flip custom: going farther in range but less damage, as well as the Rocketbarrel Kaboom custom, which provides more maneuverability with the risk of explosion if terrain is hit (she's never flown before!).
Isabelle: Property-wise, she's identical to Villager (just a smidge shorter, like Lucina), and she's lighter. However, she has the legendary Timber Counter custom, complete with the tripping sapling and Wobbuffet tree. This puts a further emphasis on zoning due to the lightweight and the new tools the new move provides.
