Magipie: An annoying fat Fairy that sets up Calm Mind and wins. The added Poison type makes it immune to Toxic, which is huge, but it comes with some additional weaknesses. I think you could compare this to Baloon pretty easily, but unlike Baloon, is far from lacking in Special Defense. It can become really quite untouchable after a CM, and the fact that it can kneecap physical attackers with Will-o-Wisp would be a big part of what makes this annoying to deal with. It would also definitely supplant Baloon almost entirely as a defensive Fairy-type, even with its addition weaknesses. So this would at worst be something that is really good and outclasses other things, and I think it could potentially be broken just based on how stupid its bulk is, but maybe not.
Dragolow: It would share the throne of speed king with Electritar, the current fastest mon in the meta. Much like Electritar, it's a blazing fast special attacker. It has a more spammable STAB type, but admittedly worse coverage. At a glance it seems broken, but when you dig in a little you see that it's potentially manageable. Bellena (unless it predicts with Specs Sludge Wave), Giranium, Barracoth, Gorilax and Glacida could be checks to it, just due to their great bulk, and the fact that even with Specs Dragolow would struggle to touch them too much. Pidgeotine, Biceon, Ninjoth, and Panthee would be able to pivot in on it and either gain momentum, set up, or just kill it. So there is definitely counterplay to it. Against offense this would be a great cleaner though, just able to spam Dark Pulse and wear down its switch-ins for later in the game. I think an apt comparison might be Specs Ash-Greninja; excellent speed tier and able to just wear down its switch-ins with Dark Pulse or cheese through with flinches, but also fairly one-dimensional and has a well-defined set of defensive counterplay. I have no doubt this would be a really good, potentially even centralizing mon, but broken? Possibly. I might just be talking shit.
Hunting: This thing is actually very similar to Voltecta, and arguably largely inferior to it. Both are physically defensive, special attacking Ghost types with Rapid Spin and the ability to pivot with Volt Switch. Voltecta has greater flexibility due to its somewhat nicer speed tier, it's also got Calm Mind, letting it also play as a setup mon, as well as an arguably better defensive typing. Voltecta has a worse offensive typing, but that almost doesn't matter since Voltecta has access to Focus Blast which is as strong as a STAB Aura Sphere. Voltecta also has the STAB Volt Switch letting it gain momentum while doing a lot of damage. So what does Hunting have? Well, Leech Seed. It's a good check to the mons in this meta that are immune to Leech Seed (the Grass types + Balar are all more physically oriented) so it can just freely throw out Leech Seed and be annoying as hell. This definitely gives it a lot more staying power than Voltecta. Is being a Leech Seeder enough to distinguish it from the otherwise superior Voltecta, and justify its place in the meta? Well IMO, no, not really. It's still just really redundant.
Dracith: In many respects it's similar to Specyte, but with even greater mixed capabilities and coverage, and Swords Dance instead of Dragon Dance to absolutely blow away defensive cores. Its flaws are even more pronounced though: it has that same poor bulk, and a really middling Speed tier that basically makes it dead weight against more offensive builds. It's also super vulnerable to Pursuit, but unlike Specyte is actually slower than Ninjoth. Its movepool is wide enough that you can easily justify fully physical or special, choiced or non-choiced sets. This is one of those super matchup-based mons, and until the full set is known, Ramron is basically the only check to it. Although I'm generally the type of player who favours high-risk breakers like this, I feel like a lot of what it accomplishes it just too similar to the other Ghost types available, especially Specyte.
Stunboon: The weirdo option. There aren't a whole lot of Ground types, so often it'll just be able to spam outrageous Choice Band Fusion Bolts. These Fusion Bolts are ridiculous, doing about 48% to Brawnkey, an insane feat for a physical move (for reference, CB Dracovish Fishious Rend would do about 57% to Brawnkey). The most physically bulky Ground type (Biceon) is hit hard by Sunsteel Strike, and Anteros can be covered with Pyro Ball. So coverage is not really a problem. Its low speed and pitiable defence would be what limit it the most, making it another one of those mons capable of outputting insane damage but falling flat against offensive teams (or pursuit trappers). It does have priority though! The extremely wonky CB Fake Out actually does an okay amount of damage with the Gorilla Tactics boost, letting it potentially pick off something weakened. So it is similar to Ostria in that respect. Overall, this one isn't too overbearing due to its prominent flaws, and I don't hate it. Electric types are fairly abundant though, and this one would play like a more unilateral Stuneleon, so idk if it's the best choice.
