The threat list is a combination of two separate lists; an offensive list, and a defensive list. Each pokemon has it's standard set or sets in brackets afterwards. This also lists it's typing, ability, stats, and if available has a short writeup and will contain links to SM analyses as available. If you wan't to suggest additions or removal, be sure to justify your input. If you want to write up an incomplete threat, feel free; if it's up to standards, it will be added to the list
Offensive Threats:
Arcanine [Extreme Speed Revenge Killer]
Fire/Flying
Pinsirite: 90/140/100/110/100/115
Ability: Intimidate->Aerilate
While Fire/Flying is suboptimal type, Arcanine at least starts in the superior pure fire state. It sets itself apart from the stronger Entei despite its lack of Sacred Fire by the ability to run Jolly and a superior movepool that contains gems such as Wild Charge, Close Combat, and Morning Sun--as well as an excellent premega ability in Intimidate. Whether it runs boosting sets with Howl, all out attacker sets that spam Return and Flare Blitz on anything slower, or defensive sets with WIll-o-Wisp and Morning Sun, Arcanine is an effective -ate user that can take on common pokemon such as Weavile without being worn down.
Arceus [Extreme Killer]
Normal
120/120/120/120/120/120
Ability: Multitype
Between its all around excellent stats, freedom of item, and excellent movepool, Arceus is a powerful offensive force. Life Orb Extreme Speed is one of the most powerful available priority moves, and Arceus can support it with varied coverage such as Earthquake, Extreme Speed, Shadow Claw, and even thunder for Blue Orb Skarmory. It can also freely boost with Swords Dance to become even harder to wall. Normal has only one weakness, letting it set up on quite a few pokemon, while it's high speed allows it to revenge KO (And prevents it from being revenged by) opposing -ate.
Arceus-Ghost [Swords Dance Sweeper]
Ghost
120/120/120/120/120/120
Ability: Multitype
Arceus Ghost has only one offensive role, but it does it well. A Ghost Typing and excellent bulk affords it numerous setup opportunities, even against top tier threats like Arceus, and almost nothing enjoys taking a +2 neverending nightmare. Its deep movepool allows it to bypass those who could otherwise take it on, from Brick Break for Normal Types to Extreme Speed for for faster sweepers to Shadow Force for a multi use STAB attack.
Aerilate Archeops [Offensive Stealth Rock]
Rock/Flying
Salamencite: 75/150/115/122/75/130, Pinsirite: 75/170/85/122/85/130
Ability: Aerilate
Cobalion [Swords Dance Sweeper]
Steel/Flying
Pinsirite: 91/120/149/100/92/128
Ability: Aerilate
With Pinsirite, Cobalion is capable of Swords Dancing up reliably. Between its great its great speed, bulk, and typing, it has very few answers. Offensively, it eliminates threats with a combination of Return and Close Combat while also being pretty impervious Revenge Killers such as -atespeeders. With its excellent steel/flying typing, it is immune to toxic and earthquake as well as numerous resistances, giving it many chances to set up for free. In addition, Cobalion has a myriad of support options; Substitute to prevent status or the few faster pokemon from taking it out, Thunder Wave to cripple other attackers, Stealth Rocks to support its team, Quick Attack to Revenge Kill, or even Volt Switch to pivot.
Darkrai [Nasty Plot Sweeper]
Dark
Absolite: 70/110/90/175/90/165, Lucarionite: 70/125/108/160/90/147, Blastoisinite: 70/110/110/185/100/125
Ability: Magic Bounce, Adaptability, Mega Launcher
Deoxys-Speed [Hazard Lead]
Psychic/Dark
Gyaradosite: 50/125/120/105/120/180
Ability: Mold Breaker
Deoxys-Speed, as the fastest Pokemon in the unboosted metagame, is a fantastic lead for offensive teams. It possesses decent bulk so it can utilize Gyaradosite to great effect and often lay down two or more layers of hazards from the beginning of the match. Deoxys-S also learns Taunt, which prevent the opponent from using Defog to clear the hazards it sets and prevents it from becoming setup bait. Deoxys occasnally also runs Dark Pukse or Psycho Boost to deal solid damage.
Ditto [Choice Scarf Imposter]
Normal
48/48/48/48/48/48
Ability: Imposter
Ditto, as the sole Pokemon with the abiliy to use Impostor, has a very unique niche. Ditto can transform into the opposing Pokemon and proceed to outspeed the foe, thanks to Choice Scarf. This makes it very helpful as a revenge killer and can countersweep some teams if they set up too early in the match, as if they cannot handle the Pokémon they have out they lose. Ditto is a fairly one-dimensional Pokemon, as it is obviously going to be Impostor with a Choice Scarf, however this does not make it any less threatening and must be played around throughout the match.
Entei [Extreme Speed Revenge Killer]
Fire/Flying
Pinsirite: 115/145/105/100/95/120
Ability: Aerilate
While its not as good of an -atespeeder as others such as Genesect, Entei is still extremely powerful--particularly since it always runs Adamant. It has access to the exceedingly rare Sacred Fire, which is a powerful Fire move able to burn opponents half of the time. Between this and Extreme Speed, many opponents can find it excruciatingly difficult to switch in, especially not more than once. In addition to those attacks, Entei has a few options for its last slots. It can run Stone Edge as good coverage against foes such as Zapdos, Return for a little more power, Will-o-Wisp to cripple Blue Orb Steel-types, or Howl for boosting.
Garchomp [Offensive Stealth Rock]
Dragon/Ground
Lucarionite: 108/165/113/105/85/124, Metagrossite: 108/140/115/90/105/142
Ability: Adaptability, Tough Claws
Pinsirite Genesect [-Ate Wallbreaker, Shift Gear Sweeper]
Bug/Flying
71/150/115/130/115/119
Abilities Download -> Aerilate
Thanks to an amazing premega ability in download, Genesect gets a free +1 boost to one of its offenses when it first comes in. Because of this, Genesect is able to either become the most powerful revenge killer in the game with a +1 STAB Aerilate Extreme or a terrifying wallbreaker that can break almost anything not named Sablenite Blissey with a terrifyingly powerful Aerilated Techno Blast or one of its many coverage options such as Flamethrower, Thunderbolt, or Ice Beam. It also gets access to Shift Gear, which in conjunction with Download boosts, Extreme Speed, and excellent offensive stats makes it a powerful late game cleaner.
Gengar [Offensive Shadow Tag, Perish Trap]
Ghost/Poison
Gengarite: 60/65/80/170/95/130
Ability: Shadow Tag
Reserved by IT11
Blue Orb Golisopod [Bulky Swords Dance]
Water/Bug
75/175/140/90/110/40
Ability: Primordial Sea
With its Bug-type granted resistance to Ground-type attacks, its high defense stat, and Primordial Sea’s dampening of Fire-type attacks, Golisopod is one of the most reliable Primal Groudon answers in the game. Between a high-powered Water-type STAB in Liquidation, dual Bug- and Water-type priority in First Impression and Aqua Jet, and reasonably reliable recovery in Leech Life, Golisopod can abuse its high attack stat and Swords Dance to do heavy damage to most defensive cores. Particularly, it easily handles troublesome defensive Pokémon such as Skarmory, Blissey, and Cresselia.
Primal Groudon [Offensive Swords Dance, Defensive Stealth Rock, Double Dance, Mixed Rock Polish, Offensive Stealth Rock, Paradancer]
Ground/Fire
90/180/160/150/90/90
Ability: Desolate Land
An extremely versatile and unpredictable Pokémon, Primal Groudon has no true counters. Access to Swords Dance and Rock Polish allows it to clean offense and stall alike, while its incredible bulk gives it manifold and multiple chances to set up safely. It has access to many high base power moves such as Precipice blades to further improve its excellent 180 attack, and can boost fire attacks with its signature sun to even further heights.
Gyarados [Dragon Dance Sweeper]
Water/Flying
Salamencite: 95/135/129/70/110/101, Pinsirite: 95/155/99/70/120/101
Ability: Intimidate->Aerilate
Gyarados is a great setup sweeper in Mix and Mega, capable of Dragon Dancing up to fearsome heights on many different pokemon thanks to its great tying and Intimidate. After a Dragon Dance Gyarados outspeeds pretty much everything, and very little likes takings its attacks. Gyarados can use substitute to set up on walls, or go for extra coverage to complement it's excellent flying and water STAB moves in either Earthquake or Stone Edge.
Hoopa-Unbound [Nasty Plot Wallbreaker]
Psychic/Dark
Blastoisinite:80/180/80/220/140/80, Lucarionite:80/195/78/195/130/102, Absolite:80/180/60/210/130/120
Ability: Mega Launcher, Adaptability, Magic Bounce
Reserved by Funbot28
Kartana [Swords Dance Sweeper]
Grass/Steel, Grass/Flying
Metagrossite 59/191/151/69/51/149, Pinsirite 59/211/151/69/51/129
Ability: Tough Claws or Aerilate
While Kartana doesn't have much movepool to speak of, it does have what it needs to succeed, and any deficiencies can be made up for by its excellent stats. In its base form, Kartana boasts an incredible 181 attack and an excellent 109 speed; with mega stones, it can bolster these still further and become a threatening sweeper. Between its powerful Grass, Steel, Normal, and Fighting type attacks, Kartana can hit anything not named Zapdos or Skarmory for heavy damage, and even those do not enjoy switching into a boosted Kartana. An excellent physical bulk and high speed stat makes Metagrossite sets almost impossible to revenge KO, while Pinsirite sets are similarly difficult to wall.
Keldeo [Calm Mind Wallbreaker]
Water/Fighting
Lucarionite: 91/107/108/154/90/130
Ability: Adaptability
Reserved by IT11
Klinklang [Offensive Shift Gear]
Steel/Flying
Pinsirite: 60/130/135/80/105/110
Ability: Aerilate
Thanks to one of the best setup moves in the game in Shift Gear, Klinklang is a potent sweeper. Shift Gear allows it to boost its speed quickly, while also boosting attack, allowing Klinklang to outspeed and clean many teams late game. With Pinsirite, Klinklang also boasts a fantastic Steel/Flying typing, which allows it to set up on many threats due to few weaknesses and many resistances. This typing also means it resists Aerilate and regular Extreme Speed, allowing for more efficient sweeps. Klinklang's coverage includes Aerilate Return, Gear Grind, and Wild Charge. While this does not allow it to hit Steel- or Electric-types particularly well, it i should still very threatening to most teams, as STAB Return hits very hard after a Shift Gear boost.
Kyogre-Primal [Offensive Calm Mind]
Water
Blue Orb: 100/150/90/180/160/90
Ability: Primordial Sea
Lucario [Swords Dance Sweeper]
Fighting/Flying, Fighting/Steel
Pinsirite:70/140/90/125/90/110, Lucarionite:70/145/88/140/70/112
Ability: Aerilate, Adaptability
What it lacks in power, it makes up for in movepool. Unlike other -atespeeders, it can quickly boost past walls with Swords Dance, stopping bulky pokemon from coming on and just sitting on it. Its second typing doesn't hurt matters, either; a powerful close combat allows it to hit any Rock or Steel types that want to take Extreme Speed. From there, it can choose between Earthquake for Electric types and Magearna, Stone Edge for Zapdos, or Ice punch for switchins such as Zygarde. To make matters worse, it also has an effective wallbreaker with it's native stone, Lucarionite, that hits those few things that answer the pinsirite set with a more powerful Close Combat and a brutal Iron Tail.
Lunala [SubCM Stallbreaker]
Ghost/Psychic
137/113/89/137/107/97
Ability: Shadow Shield
With a Substitute, Lunala blocks all status and turns almost any bulky pokemon into setup bait. Psyshock lets it bypass other CM sweepers and Blissey, while Moonghiest beam lets it CM vs Cresselia and win as well as providing a more powerful STAB attack. Versus offense, it can use it's excellent bulk and Shadow Shield to get off at least 1, and usually 2, attacks before being KOed despite its low speed. It is also immune to both Fighting and normal attacks, granting it numerous switchin opportunities, and allowing it to check most such sweepers.
Mamoswine [Offensive Stealth Rock]
Ground/Ice
Lucarionite: 110/165/98/95/60/102
Ability: Adaptability
Absolite Manaphy [Tail Glow Sweeper]
Water
100/120/100/140/100/140
Ability: Magic Bounce
While its stats are nothing exceptional, access to Tail Glow sets Manaphy apart. Being able to boost its special attack by three stages in one go lets Manaphy pick apart most bulky cores, and outpace defensive boosted that rely on moves such as Calm Mind. While it cannot beat Sablenite Blissey or certain Red Orb users, almost anything else is fair game, and an excellent ability in Magic Bounce gives it many setup abilities against common walls. Versus offense, however, it is hardly dead weight either--an excellent 140 speed allows it to outpace most staples, while its bulk is more than sufficient to live an Aerilated Extreme Speed from close to full. Between Scald, Energy Ball, Psychic, and Ice Beam, very little wishes to take it on.
Metagross [Offensive Stealth Rock]
Steel/Flying
Pinsirite: 80/165/150/105/110/90
Ability: Aerilate
Metagrossite Mimikyu [Swords Dance Sweeper]
Ghost/Fairy
55/100/100/60/125/136
Ability: Disguise -> Tough Claws
As far as setup goes, Disguise is effectively a better Multiscale; it gives an almost entirely free turn for Mimikyu to set up Swords Dance and make up for its mediocre attack, while functioning unimpeded even in the presence of entry hazards. While Mimikyu’s stats are mediocre, Disguise allows it to freely double--or more--its attack, and it's nice speed tier lets it usually get off a hit after boosting.
Raikou [CM Weather Ball Sweeper]
Electric/Fire
Red Orb: 90/115/95/165/100/115
Ability: Desolate Land
Thanks to an event-granted access to weather ball, Raikou can use the Red Orb to become a powerful attacker. Between a powerful 165 base Special Attack, a new Fire typing, and the boost from Desolate Land, Raikou can hit nearly everything for solid damage, including bulky switchins such as Primal Groudon. Unlike most fire moves, this is not blocked by Primordial Sea--the attack is weakened instead of negated, so such Pokémon cannot switch in freely. While a Rash nature hinders it somewhat, the extra power makes Raikou's difficult to wall, and it still manages to outspeeds the crowded base 100 speed tier. Raikou can viably perform as an offensive pivot or a Calm Mind sweeper, making it difficult to predict unless you scout its moveset.
Scizor [Offensive Swords Dance]
Bug/Steel
Blue Orb: 70/180/100/85/100/65
Ability: Primordial Sea
Scizor is a great Blue Orb user thanks to the rain negating its sole weakness. The extra power and bulk do not go amiss either, offering Scizor more and more effective chances to boost. Iron Head and X-Scissor hit most foes for reliable damage, while superpower demolishes steel types and Bullet Punch picks off weakened threats. Scizor can also recover health with roost, allowing it to boost up multiple times per match and serve as an excellent pivot with U-Turn.
Tapu Bulu [All Out Attacker]
Grass/Fairy
Aerodactylite: 70/160/135/95/115/95, Metagrossite: 70/140/135/95/115/115
Ability: Grassy Terrain->Tough Claws
The main thing Tapu Bulu brings to the table is sheer power. Whether it's using Wood Hammer to smash walls and bulky threats with a truly threatening level of power or sustaining itself with Horn Leech, Tapu Bulu's main role is to use the grassy terrain it sets and its postmega tough claws to nuke anything that tries to take it on. Tapu Bulu also has coverage, such as Stone Edge for Ho-Oh and other flying types, Superpower for Steel-types, and Megahorn for the many bulky Psychic types such as Cresselia and Mew. Tape Bulu also has a pair of boosting moves in Swords Dance and Bulk Up to further destroy foes. When paired with a decent speed tier, this is nearly impossible to come into; Aerodatylite sets out speed anything on stall, while Metagrossite sets can tie anything up to Kyurem-Black.
Tapu Koko [Offensive Pivot]
Electric/Fairy, Electric/Fairy, Electric/Flying
Lucarionite: 70/150/103/120/75/152, Absolite: 70/135/85/135/75/170, Pinsirite:70/145/105/105/95/150
Ability: Electric Surge->Adaptability, Magic Bounce, Aerilate
Despite its low offensive stats, Tapu Koko still hits very hard thanks to its excellent premega ability in electric terrain. Functioning as a free choice specs boost for electric type attacks, it allows Tapu Koko to function as a powerful pivot or attacker. Tapu Koko also has a powerful second STAB attack in Dazzling gleam to hit dragons, while Nature's Madness injures walls and cripple ground types like Pimal Groudon. To make things worse for any Ground or Grass types that try to switch in, Tapu Koko also has a pinsirite set that allows it to spam high powered Aerilated Returns on its usual answers.
Tapu Lele [Calm Mind Sweeper]
Psychic/Fairy
Absolite: 70/105/75/170/115/135, Lucarionite: 70/120/93/155/115/117
Ability: Psychic Terrain->Magic Bounce, Adaptability
Reserved by Funbot28
Terrakion [Swords Dance Sweeper]
Fighting/Rock
Lucarionite:91/164/108/97/90/130, Metagrossite:91/139/110/82/110/148
Ability: Adaptability, Tough Claws
While it misses out on outspeeding the very top pokemon, Terrakion is still an extremely effective cleaner. Swords Dance improves its already excellent damage output to obscene levels, while its dual STAB combination fo fighting and rock is almost impossible to wall. Terrakion can also protect itself from status and priority with substitute, while earthuake provides more coverage and stealth rock lets it support its teammates during all of the switches it cases, particularly given how it beats most defoggers.
Thundurus [Nasty Plot Sweeper]
Electric/Flying
Absolite: 79/135/70/165/80/151
Ability: Magic Bounce
Volcarona[Offensive Quiver Dance]
Bug/Fire
Red Orb: 85/90/85/185/105/100
Ability: Desolate Land
Glalilite Weavile [Revenge Killer]
Dark/Ice
70/165/65/85/85/145
Ability: Refrigerate
Thanks to its access to Fake Out and Feint, Weacile acts as an excellent revenge killer. Its high speed stat allows it to outpace even Extreme Speeders to use Feint, and let's it get off the first hit versus ordinary foes. Low Kick and Return have almost perfect coverage, but Weavile also gets moves such as Throat Chop, Swords Dance, and Double Edge to hit anything slower for heavy damage.
Xerneas [Choice Scarf, Geomancy, Z-Geomancy]
Fairy
126/131/95/131/98/99
Ability: Fairy Aura
While it cannot mega evolve, Xerneas is still a force to be reckoned with. Thanks to Fairy Aura's damage boost, even Choice Scarf sets can wear down switchins. Choice Scarf, the most common set, uses its high speed to function as a revenge killer; only Deoxys-S outspeeds it without boosts, while switchins have to contend with Grass Knot, Thunder(bolt), Close Combat and Focus Blast. Like in Ubers, Xerneas can also sweep with a Geomancy set, and while checks are stronger--and thus need to be more weakened--it is less prepared for.
Xurkitree [Offensive Tail glow]
Electric
Absolite: 83/109/71/213/71/123
Ability: Magic Bounce
Yveltal [Life Orb Attacker]
Dark/Flying
126/131/95/131/98/99
Ability: Dark Aura
Zygarde [Dragon Dance Sweeper]
Dragon/Flying
Pinsirite: 108/130/141/91/115/115
Ability: Aerilate
Due to the introduction to its new signature move in Thousand Arrows, Zygarde has become an even more dangerous offensive threat this generation in conjunction with Aerilate boosted Extreme Speeds thanks to Aerilate from the Pinsirite or Salamencite. After a single Dragon Dance, Zygarde can wreck havoc on many teams lacking a solid Flying resist that is not weak to Ground-type attacks such as Skarmory or Zapdos. Zygarde also possesses solid bulk for an offensive pokemon, which allows it many opportunities to setup and become a difficult threat that is not only hard to wall, but also take down.
Defensive Threats
Arceus-Ground [Fast Bulky Support]
Ground
120/120/120/120/120/120
Ability: Multitype
Arceus-Rock [Fast Bulky Support]
Rock
120/120/120/120/120/120
Ability: Multitype
Arceus-Water [Defensive Defog]
Water
120/120/120/120/120/120
Ability: Multitype
Blissey [Defensive Cleric, Calm Mind]
Normal
Sablenite: 255/20/60/95/185/25, Slowbronite: 255/10/80/105/135/55
Ability: Magic Bounce, Shell Armor
As the premier special wall of the tier, Blissey is extremely difficult on both sides of the spectrum. Between Magic Bounce, Softboiled, and Heal Bell, Sablenite is almost immune to being worn down, while Shell Armor allows Blissey to sweep unprepared or weakened teams while protecting against Critical Hits in Calm Mind wars.
Cresselia [Calm Mind Sweeper]
Psychic
Sablenite: 120/80/170/95/180/55
Ability: Magic Bounce
Cresselia has a near unrivaled bulk, few weaknesses, and a nice ability to protect it from status and taunt. Calm Mind fixes its weaker Special Defense, while Psyshock lets it win calm Mind wars. Although its struggles with Steel-types, it has few other issues--between psuedoreliable recovery, Moonblast for Dark Types, and its great bulk, very little can stop it after setup.
Giratina-O [Defensive Defog]
Ghost/Dragon
150/120/100/120/100/90
Ability: Levitate
Lugia [Bulky Support]
Psychic/Flying
106/90/130/90/154/110
Ability: Multiscale
Magearna [Defensive Heart Swap]
Steel/Fairy
Venusaurite: 80/113/155/152/135/65, Sablenite: 80/105/165/150/165/35
Ability: Thick Fat, Magic Bounce
Magearna has an amazing offensive and defensive typing, as well as a solid movepool like Fleur Cannon, Flash Cannon, Volt Switch, Ice Beam, Shadow Ball, and Aura Sphere. It also has Pain Split for recovery and Heart Swap, which can be used very well to steal other stats from setup sweepers like Cresselia, and also cripple incoming pokemon via a Fleur Cannon + Heart Swap combo. It can use almost any defensive stone very well, all which give it more defensive capability and at the same time make it a better nuke.
Mandibuzz [Defensive Defog]
Dark/Flying
Sablenite: 110/75/155/75/145/50, Venusaurite: 110/83/145/77/115/80
Ability: Magic Bounce, Thick Fat
Milotic [Bulky Phaze]
Water
Sablenite: 95/70/129/120/175/51
Ability:Magic Bounce
Alolan Muk [Bulky Pursuit Trapper]
Dark/Poison
Lucarionite
Ability: Adaptability
Alolan Muk is a new Pokemon introduced with the new generation, and despite seemingly subpar stats, it is blessed with a fantastic typing and just enough attack to be a fantastic addition to stall teams. Despite a lack of reliable recovery, Muk-Alola serves an important role on stall, as it can switch in on and trap Hoopa-Unbound and Mega Gengar, two of the most difficult Pokemon for stall to counter. With Lucarionite, 252 attack EVs, and an Adamant nature, it guarantees the OHKO on most variants of Hoopa-Unbound with Pursuit (if they switch), as well as OHKOing Mega Gengar, preventing them from doing their stall- and wallbreaking jobs. It also does a lot of damage to Cresselia with Adaptability-boosted STAB Crunch, making it a very useful Pokemon on the newly viable playstyle that is stall.
Scizor [Bulky Pivot]
Bug/Steel
Blue Orb: 70/180/100/85/100/65
Ability: Primordial Sea
While its stats are far better suited for an offensive role, Scizor's unique combination of type and movepool allow it to function as an able defensive pivot. A Defogger that is both neutral to rocks and has no weaknesses is a great boon for any team, and it can U-turn to preserve momentum or use Toxic to threaten certain switches. An excellent steel type prevents it from being worn down with toxic itself, and reliable recovery in roost let it do so multiple times. Because of how much it walls, it excels at gaining free turns, which lets it either remove hazards for the team with Defog freely or steal back momentum.
Skarmory [Defensive Hazard Manager]
Steel/Flying
Blue Orb: 65/130/140/70/90/70
Ability: Primordial Sea
Tapu Bulu [Bulky Attacker]
Sablenite: 70/140/165/105/145/45,Blue Orb: 70/180/115/115/115/75
Ability: Grassy Terrain->Magic Bounce, Primordial Sea
Togekiss [Stallbreaker, Bulky Defog]
Red Orb: 85/80/115/170/115/80, Sablenite:85/60/145/140/165/50
Ability: Desolate Land, Magic Bounce
Toxapex [Defensive Toxic Spikes]
Water/Poison
Sablenite: 50/73/202/73/192/5
Ability: Regenerator->Magic Bounce
Toxapex with Sablenite has insane defenses, Magic Bounce, and a decent support movepool with Recover, Baneful Bunker, and Toxic Spikes. It also has haze, which can neutrilize opposing sweepers. While it's HP stat is lacking, it's still very bulky, and it can use its premega ability of Regenerator to freely pivot before it needs the bulk from Sablenite. Should toxic spikes be reflected back by magic bounce, it can also switch in and absorb them.
Yveltal [Tough Bird]
Dark/Flying
126/131/95/131/98/99
Ability: Dark Aura
Zapdos [Defensive Defog]
Electric/Flying
Venusaurite: 90/108/125/147/110/100, Sablenite: 90/100/135/145/140/70
Ability: Thick Fat, Magic Bounce
With Venusaurite, Zapdos is able to freely Defog on support Primal Groudon, setting Toxic and stalling it out while ignoring both Lava Plume and Precipice Blades. It also walls dangerous sweepers such as Genesect, Zygarde, Lucario, and Weavile. With Sablenite, Zapdos swaps out Genesect, Weavile, and Kyurem-Black for Support Arceus and a more proactive ant-hazard role. Zapdos can also steal momentum with U-Turn or Volt Switch, and cripple switchins with Toxic.
Zygarde-Perfect [Defensive Resttalk]
Dragon/Ground
216/100/121/91/95/85
Ability:Power Construct
Thanks to its excellent HP stat, Zygarde becomes on of the bulkiest pokemon in the game, even without a mega stone. While Rest is not the most reliable recovery, it prevents status as well, so the only ways to wear down Zygarde are Taunt and strong attacks--and mostly special ones at that. Zygarde can also simultaneously increase its bulk and damage with Coil, while Shuffling switchins with dragon tail or just abusing the excellent coverage of Thousand Arrows.
