Ability speculation for revealed Megas by Eeveeto.
Will post 3 logic abilities for each (well, most) revealed Mega based on design, typing and Pokedex entry. This holds no value in this game, but if they are introduced into the main saga, ability will determine viability. Therefore, predicting them looks fun.
Clefable:
First thing I want to mention about this guy is that it might be getting Quiver Dance. Has wings (even without Mega), known to like dancing. This of course would make it demonic competitively, since it also learns Stored Power and can heal with Moonlight.
1. Magic Guard. Nothing original, just keeping a good ability it already has. Since its weak to Rocks, it would come handy.
2. Unaware. Same reasoning, already good ability that it has. No status or Hazard immunity, but the superior bulk the Mega has, means it can check lots of Mons, while boosting with CM or the for now uncofirmed SD.
3. New ability that triggers Gravity. This is based on the Pokedex entry alone "It flies by using the power of moonlight to control gravity within a radius of over 32 feet around it." I don,t think this is very likely due to Clef having the Flying type. It does allow to use Blizzard, Thunder or Fire Blast from 135 Special Atack, however.
Victreebel:
This guy has been robbed hard in terms of Stats. That being said, it can be saved by a good ability.
1. Corrosion. Known for its Acids, this is very likely and hope it ends up being it. Despite being robbed in Stats, Victreebel gained bulk. It has slightly lower physical bulk than Glimmora, but higher special. On both sides it has much more bulk than Salazzle, therefore it would be the best Corrosion user. Unlike the other 2, it has Synthesis and is not murdered by the best Toxic absorber, which is Gliscor. Corrosion would give Victreebel a big niche.
2. Poison Touch. It pursuits preys now instead of waiting them, so it could have this. It has Leaf Blade, Knock Off, Poison Jab and Sucker Punch. Its much worse than Corrosion, but not useless.
3. New ate ability, similar to Refrigerate, but for Poison moves. Very unlikely, and not very good, since Poison is a bad typing.
Starmie:
Pure Power or Huge Power, nothing to see here, we know for certain what it will have.
Dragonite:
Weird Mega that now is Special. I am quite certain it won,t have Aerilate. Not certain whether it will be good, but its still Dragonite, so by Stats alone it will be viable, just like Mega Garchomp was.
1. Soul Heart. Kind Mon that finishes foes with mercy in its heart. This makes sense. Its an ability that for now only Magearna has, but Drought and Drizzle also were abilities exclussive to legendaries before Ninetales and Politoed got them.
2. No Guard. Hurricane its Dragonite's strongest Special move, if it always hits, it will be good. Dragonite also learns Draco Meteor, Thunder, Fire Blast, Blizzard or Hydro Pump. Slower than Pidgeot, but still better otherwise.
3. Multiscale. Of course, we can,t discard it just stays with the original good ability. No Boots, so learn to support it with spinners.
Meganium:
This has always been my favorite starter across all Gens and the Mega did not dissapoint...outside of not having Moonblast. But there is a way to solve that:
1. Pixilate. Meganium does not learn Hyper Voice either, but thats a move much easier to add to Mons than Moonblast, half of the Pokedex learns it.
2. Flower Veil. I don,t know whether what Meganium has around the neck qualifies as a Veil, but it would be a very good ability for it. No Stats drops (which means, Specs Pult locked in Shadow Ball is not breaking this) and Status immunity would allow Meganium to be a very good tank that is hard to wear down.
3. Aroma Veil. Pokedex entry: "The aroma that rises from its petals contains a substance that calms aggressive feelings." Worse than the previous one, but still has its uses.
Feraligatr:
Meme Mega... but should be cool competitively. Its not a Fish, so its getting Fishious Rend.
1. Strong Jaw. All about Feraligatr are its jaws, so this is quite likely. Ice Fang and Crunch are unfortunately the only moves that benefit.
2. Tough Claws. Less likely, but benefits way more moves.
3. Sheer Force. Might as well keep what is already decent, though no LO to benefit from.
Skarmory:
As I keep saying for a long time, after being in OU between Gen 2 and 8... this Pokemon sucks incredibly hard in SV OU due to Ghost and Tera Ghost Mons abusing its existance. Mega gives it a new life and it has an epic design.
1. Sharpness. Its sharp and this is a very cool ability. Aerial Ace is unfortunately the only physical STAB that benefits from it, but with 140 Attack it might be enough. X-Scissors is bad on Skarm, Slash is worse, but Night Slash is actually useful to pair with Body Press, so the Ghosts that normally abuse Skarm are screwed.
2. Tough Claws. Pokedex description: "It flies faster than the speed of sound. After whipping up shock waves to send enemies flying, it finishes them off with its talons." All Skarmory moves make contact, so this would probably be even better than Sharpness, though far less likely.
3. Good as Gold. Its golden. That would be the entire justification. It would make Skarmory as the most balanced version of Gholdengo. No Wows to ruin its sweep, no Taunt to block it, no Defog removing hazards, but at least you can still Spin.
Froslass:
One the big 3 in terms of design (Skarmory and Chesnaught are the other ones).
1. Snow Warning. I mean, its an Ice type. I liked it more when Hail dealt damage, but the Defense boost allows Froslass to either set Spikes or boost with Nasty Plot. BoltBeam at +2 from 140 Special Attack will hurt.
2. Some new ability that makes Freezes happen more often. I don,t want this, since it would likely be unfairly banned.
3. Snow Cloak. I also hope we don,t get this, since it would also be unfairly banned.
Emboar:
Out of the 3 Fire Fight starters, this has always been the one I liked most. Hopefully it gets Slack Off.
1. Supreme Overlord. Looks like a general. It would be a worse Kingambit, but it would actually beat Kingambit. It does learn Non-STAB Sucker Punch.
2. Defiant. "Brandishing a blazing flame shaped like a serpentine spear, it rushes in to rescue its imperiled allies." Brave Mon with a brave ability.
3. Guts. Same reasoning here. Not very good due to not being activated by burns.
Scolipede:
Due to the Stats changes, this Mega will be entirely carried out by the ability choice.
1. Tinted Lens. This would allow to Protect + SD to be run on the same set.
2. Merciless. "Its deadly venom gives off a faint glow. The venom affects Scolipede's mind, honing its viciousness." The second part of this qualifies for this. It would require teammates support.
3. Toxic Debris. It has a lot of Spikes. Pretty sure some of them are easy to fall. With the new bulk, it could activate this ability a lot. Much worse than Tinted Lens and unlike Glimmora takes Mega slot, but it has its use.
Scrafty:
Idk what to think of this one... Would have liked Krookodile more. Its nonetheless a very strong Mega.
1. Shed Skin. Literally already has it and mentioned in the Mega Pokedex description. Very good ability.
2. Wonder Skin. Skin is the most important body part this guy has and this would be a good way to promote the broken ability that for now only Bad Mons have.
3. Prankster. It gained Parting Shot. This would be a very good way to use it, given that the Dark types that are immune to it, get hit by Fight STAB.
Eelektross:
Well, at least it now outspeeds the walls it intends to break. Like 323121 other Mons.
1. Levitate. Why change what already works?
2. Transistor. "It now generates 10 times the electricity it did before Mega Evolving." This would be the justification. And it would be neat, unlike Regieleki, it has Grass and Water coverage for Grounds.
3. Dry Skin. Lives in Water, so makes sense. I don,t think trading Ground immunity for this is a good trade though.
Chandelure:
Nuclear power is good, but why would I use this over Specs Hisuian Typhlosion or Blacephalon?
1. Shadow Tag. Well, this is why. Except it would go to Ubers one minute after arriving.
2. Cursed Body. Common Ghost ability. Not very good, but RNG is always fun.
3. Infiltrator. Another common Ghost ability. Screens and Subs now don,t protect you from 175 power Overheats.
Chesnaught:
This is the Mega I like the most. I might be biased, since Chesnaught was already my favorite Kalos starter, but it looks even cooler as a Mega. Stats distribution made this Mon very optimized, though the typing is still mid.
1. Bulletproof. Another case of "Why change what already works"?
2. Battle Armor. "It has fortified armor and a will to defend at all costs. Both are absurdly strong." Goes very well with the warrior theme this Mon has. This ability could allow Chesnaught to invest in Sdef and run IronPress, never being critted.
3. Rough Skin. I see lots of Spikes on Chesnaught's body. So far, the only Iron Barbs/Rough Skin Mon with recovery was Togedemaru, which has Wish. Despite Synthesis having less PP, Chesnaught should be able to last longer and cause passive damage.
Delphox:
Another good design, which also comes with a rare typing.
1. Magic Guard. Fits for a wizard theme and protects Delphox from hazards and Poison. Would make it an offensive powerhouse.
2. Magic Bounce. Same reasoning here. Harder to use, but the reward is also higher.
3. Levitate. Withes fly, so why wouldn,t Mega Delphox be able to do the same? Removing one of the 5 weaknesses is useful, though it would still be vulnerable to Rocks.
Greninja:
Out of the 3, the one I like less. This was not the case with the base Mons, I liked Gren more than Delphox.
1. Infiltrator. Ninja theme, fits very well. Not the best ability, but Dragapult makes good use of it.
2. Skill Link. This would work for only one move, but Modest Nasty Plot Water Shuriken in Rain should be able to do a lot of damage. It could also allow Greninja to invest in bulk and power instead of Speed, which is already high uninvested.
3. Protean. See first Chesnaught's ability.
Pyroar:
Boring Mon, boring Mega. At least it got Earth Power now.
1. White Smoke. Immunity to Sticky Web. Rare ability that could somewhat work.
2. Rivalry. On gender related Mons this is common. Very unreliable though.
3. Intimidate. Arcanine has it, Manectric has it, Incineroar has it, why a lion wouldn,t?
Floette Eternal:
I hope this finally makes it to a mainline game.
1. Regenerator. Eternal life. Simple and very good.
2. Natural Cure. Pretty much the same reasoning. Not as good on an offensive Mon, but useful to heal paralysis.
3. A new ability that makes Grass moves 50% stronger. Apparently the flower now attacks on its own, so it could be a second STAB, though it wouldn,t be very effective.
Malamar:
Never liked this Mon and the Megas isn,t impressive either. This should have been a Gogoat or a Pangoro instead.
1. Contrary. Almost 100% sure its this one. Stats are too lackuster otherwise.
2. Simple. Of course, with so many set-up moves, this is also an option.
3. Moody. This guy is a villain, like Scovillain, who has the same ability. A shame Smogon does not allow fun.
Barbaracle:
Regardless of the ability, this Mega has a decent chance to end up in Ubers. Mega, Shell Smash and type change (which allows mind games) in one. Mega Blastoise was banned for less in National Dex (fake meta though).
1. Tough Claws. Another case of a Mon in which the already good ability might stay.
2. Skill Link. Just like with Greninja, only works for one move, but Rock Blast hitting 5 times at +2 is enough vs most of the meta. Mega gaining Fight type means it could also get Arm Thrust, though CC is better.
3. Trace. It has many brains, so it might as well use them to copy the ability of the opponent. This could be funny if the opponent is Shedinja.
Dragalge:
Did not expect the cancer lore. Regardless of what it does, this is a Trick Room Mega.
1. Corrosion. If the liquid is deadly to everything other than itself, it might be something very Corrosive. Dragalge has ways to threaten Gliscor. The great bulk would make this very interesting.
2. Regenerator. Regenerative power of cells. If they are its own cells, its good. A Regenerator Mega with good offensive power and 65/105/165 bulk is nothing to underestimate, especially since it also has Flip Turn.
3. Merciless. Another Poison ability that could fit.
Hawlucha:
70% of times people lost to this Mon in OU meta were because their team were either poorly built or they played them badly. I include my own loses in this statistics, the Mon is very fraudulent and overrated. Hopefully the Mega changes it.
1. Tinted Lens. Only way of making Flying Press somewhat good, in case they want to do it.
2. Reckless. HJK + Brave Bird abuse.
3. No Guard. Doesn,t learn Dynamic Punch unfortunately, but HJK, SE and Dual WIngbeat are right there. Both this and the previous ability come from the Pokedex description: "Hawlucha flexes to show off its strength."
Zygarde:
No Speculation here. Both previous Zygarde abilities are exclussive to it, so it probably will get something completely new. Also, does it need to be 100% and activate Power Construct to Mega Evolve? Does it need a Megastone? Regardless of that, this snake is Uber and might be even AG. Hopefully the 50% one returns to OU, with its movepool nerfed (unlikely to retain Toxic and Rest now has only 8 PP).
Drampa:
Would have liked a Mega Palossand or Toucannon, but this is not a bad choice for an Alola Mega.
1. Regenerator. "Drampa's cells have been invigorated, allowing it to regain its youth." As 90% of the Mons, it would be extremely good with this.
2. Drizzle. "It manipulates the atmosphere to summon storms." Learns Thunder, Hurricane and Hydro Pump. There is no Drizzle Mega yet, only weather that remains.
3. Friend's Guard. This comes more from the base form Pokedex, but fits.
Falinks:
With only 1 Galar Mega, this has been the best choice. Would have hated a Mega Toxtricity or Mr. Rime.
1. Battle Bond. Ok, let me explain this one. In Gen 7 and 8 this was the description of this ability:
"Defeating an opposing Pokémon strengthens the Pokémon's bond with its Trainer, and it becomes Ash-Greninja. Water Shuriken gets more powerful."
In Gen 9 it changed to this:
"When the Pokémon knocks out a target, its bond with its Trainer is strengthened, and its Attack, Sp. Atk, and Speed stats are boosted."
And Mega Falinks Pokedex description is this:
"Mega Falinks has taken on the ultimate battle formation, which can be achieved only if the troopers and brass have the strongest of bonds."
So, the ability doesn,t mention Greninja anymore, meaning more Mons could have it. Therefore, a Pokemon that depends on strong bonds would be an ideal receptor. No Retreat, kill something and go wild.
2. A new ability that makes each move hit 6 times at a reduced power. Do I need to explain this one?
3. Battle Armor. A way to ruin Falinks after No Retreat are crits. Well, not anymore. One more of the list of abilities that No Mega Mons already have.
Won,t speculate on either of the Raichus. They are too similar to each other and might go in any direction possible. For what is worth, they might even have Plus and Minus.
Have a nice Eeveening and crazy Speculation!
