Flareon - Fur Coat / Fluffy, take away Yawn OR Sizzly Slide + Intimidate
- Deadass, Flareon is honestly not a horrible defensive Pokemon, but its big issue is its lacking physical defense. It just leads to it having the bad combination of being slow and frail, forcing it into a bad situation vs many dangerous physical attackers. I think Fur Coat would go a long way of improving both its defensive & offensive role, while also not even being overpowered since Flareon needs to heavily invest in physical bulk to not get overwhelmed by stuff like Gambit. This pokemon still would likely be outclassed by Arcanine or Dirge, but it can perform roles they can't such as Calm Mind. Alternatively, Flame Body could also work but would be much less impactful. Fluffy also works, as a new potential ability.
- Offensively, I do not think this Pokemon can be salvaged since there are too many broken Physical Fire-types it is competing with & no buff it recieves will bring it up to the same power level as them aside from some insane shit like Swords Dance + Fire-type extreme speed clone.
- Sizzly Slide would be cool move for it to get, but in that case, it might need a different ability since it may be too powerful in tandem with Fur Coat. Intimidate perhaps, but not very lore fitting.
Vaporeon - Regenerator, take away Yawn, Baton Pass, & Wish OR Bouncy Bubble + Storm Drain
- Yes, very cringe & uninspired, but I think it fits with Vapreon's theme. I don't want this shit keeping Yawn & Wish if it has Regenerator though. With Regen, it would be a nice, brainless defensive pivot that can flip turn to its allies, perhaps Roar away setup sweepers, and exert pressure through Scald, alluring voice, ice beam, etc.
- Bouncy Bubble would be an amazing buff as well for Calm Mind sets. Tera Poison Calm Mind, Acid Armor, Bouncy Bubble, and either Roar or Alluring Voice would be annoying threat for sure. May be too much in tandem with Regenerator however, so perhaps Storm Drain would be warranted as smaller buff.
Jolteon - Electric Surge, take away Rising Voltage
- Another cringe uninspired pick. I don't think Jolteon has many abilities it feasibly could recieve that would improve its viability to the level it needs to be. This would just make it a tapu koko side grade, trading defensive utlity for better power on its Electric attacks. Alternatively, static could work but that would barely affect this Pokemon's viability.
Umbreon - Poison Heal, take away Yawn, Calm Mind.
- Very cringe ability yea, we would just have spdef version of Gliscor. Still, it would more or less be a passive blob compared to Gliscor, who has every entry hazard at its disposable + SD & by taking away CM, it likely won't be able to exert a gamebreaking threat with some cheese set up set. I think removing Yawn would also be nice, though I'm not sure it would make up for how cheap it might become.
Espeon - Mega Sol, give it Solar Beam
- I think Magic Bounce is probably the best ability this Pokemon could have recieved, but Mega Sol would be cool for fun offensive strats. Increased recovery from morning Sun doesn't matter too much, but being a Psychic with super powerful Fire coverage would be cool in doubles I think with Expanding Force and Solar Beam, while a bit worse generally than Alluring Voice, would be cool to let it snipe TTar and Samurott-Hisui. IDK if this would make it good, but it would make it very unique which IMO is more important.
Glaceon - Adaptability, give it Earth Power
- Considering how people find Kyurem impossible to counter, I think Glaceon is just 1 coverage move away from being solid. This Pokemon's role is just spamming big damage anyways with Specs Freeze Dry / Blizzard, so Adaptability lets it do that better, perhaps to an even broken extent, while also not taking away niche from other Pokemon like Vanilluxe, which would still have Snow Warning as its own advantage. IDK, I may have gone to far with this one, esp since its also a bit uncreative by making Glaceon a one button clicker.
Leafeon - Sharpness, give it Shadow Claw or Sappy Seed + Rough Skin.
- Pretty obvious buff. Improves damage output considerably while also giving it perfect coverage + letting it run meme items like Scope Lens easier if you wanna gamble lol. Would make Leafeon a bit of threat vs Stall builds relying on Dozo as well, though your damage unboosted vs Corv is really really bad lol - like SHOCKINGLY so (you only 2HKO it with a Crit + SD boost like WTF?) so maybe magnezone support will be needed.
- Sappy Seed is another buff that could be given & I think it would be quite busted lol. Its like a better version of Salt Cure, though Leafeon's other traits are quite as potent. It would certainly make Leafeon a more unique threat though & you could maybe combine Sappy Seed passive damage with Rough Skin to be extra cheap.
Sylveon - Natural Cure, alternatively Misty Surge, remove Misty Explosion, Swirly Swirl
- Really lame ability, but out of the Eeveelutions, Sylveon is already the best. Its pokedex entries mention its ribbons having Soothing Aura and reducing hostility, kinda similar to Heal Bell. So natural cure seems the most fitting, with there being a bit of a trade off between removing status effects vs extra power on its Fairy STAB. Alternatively, Misty Surge would be a more powerful ability which kinda gets the same status blocking effect & has the same trade off as Natural Cure, though I believe Misty Surge would be much prefered. Would allow Sylveon to fit into many more team comps as well.
