Froslass, the Snow Land Pokémon. When it finds humans or Pokémon it likes, it freezes them and takes them to its chilly den, where they become decorations. It freezes prey by blowing its -58 degree Fahrenheit breath. It is said to then secretly display its prey. It freezes foes with an icy breath that is nearly -60 degrees Fahrenheit. What seems to be its body is actually hollow.

Overview

The gender locked alternative version of Snorunt, Froslass does its best to weaponize its speed to full effect. Base 110 Speed is a great baseline to hit, outspeeding many popular Mega Evolutions and staples while tying with a few others, allowing Froslass to move first more often than not. Froslass uses this to great effect, in both typing and movepool Ice being one of the most valuable offensive types in the game excels when placed on fast Pokémon, allowing Froslass to exercise its potent STAB against the main quadruple weak staples running around like Garchomp and Dragonite, as well as the many other Ice weak targets running around like Hippowdon, Mega Clefable, Serperior, and Mega Meganium just to name a few. A potent STAB is not all Froslass brings to the table either. Froslass’ Ghost typing leaves it with no shortage of disruptive moves to harass and harry many a foe including Taunt, Will-O-Wisp, Destiny Bond, Thunder Wave and as a gift from its own evolutionary line, Spikes.

Speed is all that Froslass has going for it. Base 80 offenses means that Froslass is reliant on type matchups to deal damage and even then, will miss knockouts on bulkier targets despite having super effective STAB. This is rather distressing given Froslass’ below average base 70 defenses and unimpressive base 70 HP, giving Froslass not a lot of staying power to begin with. Add in the weakness laden Ice typing and the extremely common Ghost and Dark weaknesses that the Ghost typing provides and Froslass is laughably easy to remove. With Froslass being as frail and weak as it is, the only thing keeping it from setup fodder is its diverse disruptive movepool, but even then Froslass cannot hold every move it needs for every situation. These traits also mean that anything that can bypass Froslass’ vaunted speed, whether through priority or higher speed, whether it be natural or through some boost can quickly place Froslass on the backfoot. While Froslass does have the tools to excel as a Spikes lead, its fragility means it struggles to get up multiple layers of Spikes, let alone reestablish them if they get removed. This has Froslass compare less than favorably to other hazard setters like Glimmora who is more efficient in its setup, or Hippowdon, and Skarmory who can set hazards repeatedly, or Hisuian-Samurott or Excadrill who provide offensive pressure in addition to their hazard duties. Froslass’ good speed and moveset give it plenty of utility, but its failing in every other area holds it back.
Positives
Incredible disruptive movepool that can ruin a Pokémon in just about every way one can imagine.
Fantastic Spiker with Rapid Spin Immunity and STAB that threatens most Defoggers
Base 110 is a solid speed tier, outspeeding many offensive staples and just about every defensive one.

Negatives
Below average offenses force Froslass to rely on Super Effective hits to get knockouts if at all.
Ice Ghost typing is poor defensively with plenty of exploitable weaknesses.
70 defenses across the board gives Froslass little staying power and makes it easy to remove.

-Taunt
-Destiny Bond
-Ice Beam
Ability: Cursed Body
Item: Focus Sash
Stats and Nature:
32 HP / 2 Def /32 Spe
Timid Nature

One avenue where Froslass does excel at is that as of a lead, setting Spikes, denying opponents their own hazards and hopefully taking an opponent down with it. Spikes is Froslass’ bread and butter, being flat damage on nearly all grounded targets. While Froslass does struggle to consistently get more than two layers up, even one layer can pay dividends, breaking opposing Focus Sashes, and punishing positioning wearing down defensive checks to the point where they can no longer wall the Pokémon they are intended to. Taunt servers multiple purposes, both denying opponents setting up their own hazards, and denying setup sweepers from their own setup. Taunt also synergizes well with Destiny Bond, forcing opponents to attack and thus opening themselves up to being removed from the battle along with Froslass. This also creatures vicious mind games with Froslass; does one attack and remove Froslass while risking Destiny Bond? Or do they switch out and potentially let Froslass get up another layer of Spikes? Ice Beam is so that Froslass isn’t entirely crippled by opposing Taunts on top of being able to exercise Ice’s wide coverage and maim if not remove extremely vulnerable to Ice targets like Garchomp, and Hydrapple while maiming others like Dragonite, and Hydreigon.

Stats and Items:
Max HP and Max Speed are recommended. Lead Froslass is at its best when it is outspeeding the opponents, to more assuredly deny hazards and opposing setup as well as catch opponents off guard with Destiny Bond so max Speed with Timid nature is all but a must. Everything else is going into HP to maximize Froslass’ bulk and the chance it will survive a blow. While Froslass is on the frail side, any chance to survive an extra attack should be taken, allowing for Froslass to get up more Spikes or cause more disruption. If running Triple Axel, going Jolly instead of Timid is recommended instead. Going for full Special Attack just to get the most returns out of Ice Beam is also a valid option, allowing Froslass to chip its opposition down even more. Going full Special Attack turns Ice Beam from doing 32-37% to offensive Glimmora up to 42-49%, while Aerodactyl jumps from 68-81% to a 50% chance to bring it down to Focus Sash. Speaking of Focus Sash, that is the recommended item for lead Froslass, ensuring it will survive one hit which can make all the difference in setting up a layer of Spikes, Taunting or throwing out a Destiny Bond. Focus Sash also grants multiple opportunities to disable the attacker’s move with Cursed Body, potentially depriving the target of vital coverage needed to handle Froslass’ teammate.

Partners:
Froslass is an enabler for aggressive teams with its Spikes support and can facilitate setup sweepers with the right support moves. Froslass will often draw in Ice resists from trainers expecting its fearsome Mega Evolution, so Pokémon that counter those are ideal. Garchomp is notable thanks to its access to Stone Edge and STAB Earthquake for Mega Charizard Y and (Mega) Tyranitar, two of Mega Froslass’ biggest checks as well as easily handle other Steel and Fire types and can even potentially setup its own hazards in Stealth Rocks or stack damage with Dragon Tail. Mega Lucario crushes Dark types like Meowscarda, Tyranitar and Kingambit or make use of the more crippling aspects of Froslass’ moveset for easy setup with Swords Dance or Nasty Plot. (Mega) Greninja is also notable for packing coverage for Fire, Rock, Ghost and Dark types while greatly appreciating Froslass’ Spikes in softening up its targets.

Other Options:
Thunder Wave is fantastic persistent Speed control, ensuring that if a target is faster than Froslass or its teammates, it won’t be for long. Will-O-Wisp ruins opposing physical attackers, turning such Pokémon into setup fodder. Triple Axel is a STAB option that allows Froslass to bypass opposing Focus Sashes, but also triggers Garchomp’s Rough Skin (breaking Froslass’ Focus Sash) and Glimmora’s Toxic Debris on top of being inconsistent. Ice Shard is good for picking off opposing Focus Sash leads. Shadow Ball is good for staving off Hatterene, but the good neutral coverage of Ghost is otherwise wasted on Froslass’ mediocre Special Attack.

Countering Froslass

Froslass’ diverse array of disruptive options can make it a pain to handle but once taken out of the equation, Frosslass’ lacking bulk and power are quite exploitable.

Magic Bounce users like Hatterene and Mega Sableye are anathema to lead Froslass who rarely carries Ghost coverage, as Froslass can’t lay down Spikes, deny setup with Taunt or cripple with any status. Mega Clefable can struggle with Froslass regardless as even when fully invested into Defense, Triple Axel and Ice Beam can 2HKO provided Froslass has invested into the respective offensive stat.

Otherwise, the best way to cut through Froslass’ tricks is speed. Froslass becomes very limited in what she can do if the opponent is faster than her, as she can’t preemptively Taunt, launch a surprise Destiny Bond or preemptively cripple with status. This is obfuscated by Froslass all but always running Focus Sash to survive one hit, so it would need to be a faster attacker that can KO through Focus Sash. Scarf Tyranitar works well in this regard, able to OHKO with Rock Blast while outrunning, though Tyranitar works well in general thanks to its Sandstream passively ruining Focus Sash and fearing nothing but Will-O-Wisp. Mega Lopunny can safely break Focus Sash with Fake Out, deny Mega Froslass a turn and OHKO with Close Combat. Adamant Mega Aerodactyl is favored to OHKO with Dual Wingbeat, but it is not guaranteed, and can get OHKO’d by Triple Axel, take 73-89% from Ice Beam or be crippled from Thunder Wave or Will-O-Wisp. Speedy Taunt users like Aerodactyl, Whimsicott, and Maushold also can stop Froslass’s tricks before they can start, though most of these Pokémon want nothing to do with Ice STAB.

Fast and priority attackers are still an issue for Froslass even when they can’t bypass Focus Sash, capable of limiting Froslass’ shenanigans to one move before knocking it out when down to Focus Sash. For priority attackers in particular, Scizor is the most evident, its Bullet Punch a solid OHKO if it wasn’t for Focus Sash. Hisuian-Samurott is notable in that it can bring down Froslass to Focus Sash while setting up Spikes with Ceaseless Edge and then finish Froslass off with Aqua Jet. Scarf Gholdengo abhors the rare Shadow Ball, but its Good as Gold means that many of Froslass' more disruptive tricks are ineffective and threats quick knock outs with both STABs. Ceruledge is also notable, thanks to its resistance to Ice and immunity to Burn, alongside Shadow Sneak, giving Froslass very few options to answer it. Azumarill, Gallade, and Palafin, are also excellent priority attackers, to say nothing of the naturally faster Mega Gengar, Sneasler, Mega Starmie, and Mega Delphox all fit this role well.

For Froslass relying on status, Lum Berry is an excellent way to mess with Froslass, causing it to waste a precious turn and if the target is naturally faster, can remove Froslass without it having contributed at all.

Otherwise, tanking and removing Froslass is not an issue; its low offenses and limited move space ensures anything not weak to Ice (and a lesser extent Ghost), can handle Froslass without much issue. For Froslass isn’t the real danger, it is what it has down to prop up its teammates.

Mega Corner

Mega Froslass the Snow Land Pokémon. This Pokémon can use eerie cold air imbued with ghost energy to freeze even insubstantial things, such as flames or the wind..

Overview

One of the new Mega Evolutions introduced in Z-A, Mega Froslass dials up the Yuki-onna allusions to 11, becoming one of the most fearsome Ice types in all of Pokémon. This is thanks to its access to Snow Warning of which Mega Froslass can use to the fullest extent. As Ice is an inherently offensive type, Ice types prefer being fast than slow as to wield their fantastic STABs and this is doubly true of Snow Warning users who wish both launch perfect accuracy Blizzards and setup the amazing Aurora Veil. Mega Froslass has speed in spades; at a whopping base 120 Speed Mega Froslass is absurdly fast, outrunning even already fast Pokémon like Mega Staraptor, Mega Raichu X, and Mega Metagross, leaving few Pokémon that can land a hit before Mega Froslass either ices them or brings up the shields. It is not just Speed Mega Froslass brings to the table either; at base 140 Special Attack, Mega Froslass solves the power woes of its base form. Mega Froslass’ Blizzards rank among the deadliest in the game with their high base power making up for the lack of an item boost. Add in Thunderbolt and STAB Shadow Ball for coverage and there isn’t anything Mega Froslass can’t hit for at least neutral damage which can be quite terrifying given Mega Froslass’ access to Nasty Plot. Even on defense, Mega Froslass isn’t too bad. With Aurora Veil up, 100 Special Defense is quite durable and with the boost from Snow the fact that Mega Froslass’ base Defense was untouched means little as upon Mega Evolving it becomes even bulkier physically than specially. Moreover, is Mega Froslass’ access to the same incredible disruptive movepool of its base form allowing it to pack the perfect answer for troublesome checks.

Yet for all Mega Froslass’ strengths, it is still subject to the environment around it. While as a Mega Evolution, Mega Froslass is reliable at setting its favored weather, the popularity of other weather setting Mega Evolutions and Pokémon in general can take Mega Froslass out of its Snow and place it on the back foot. Extremely distressing is the popularity of Mega Charizard Y and Mega Tyranitar, both Mega Evolutions that outslow Mega Froslass, thus winning the weather war and have an incredibly positive matchup into Mega Froslass regardless. Furthermore, as Ice is a horrid defensive typing, it is inadvisable to partner Mega Froslass with other Ice types, limiting the benefits of Mega Froslass’ Mega Froslass’ poor typing brings up another wrinkle in that there is no lack of popular Pokémon common to many teams that give it trouble. Steel types like Kingambit, Mega Lucario, and Scizor, Fire types like Volcarona and Mega Delphox, Dark types like Greninja and Meowscarada and more, every team is packing several answers to Mega Froslass, quickly overwhelming its only marginally improved defenses. Despite the inclement conditions, Mega Froslass has excelled, and its checks must be managed lest everything in Mega Froslass’ path be buried in a wave of white.
Positives
Base 120 Speed is fantastic, making Mega Froslass difficult to outspeed.
Base 140 Special Attack is frightening, ensuring Mega Froslass hits hard even before considering Nasty Plot
Snow Warning is an amazing ability, enabling powerful no miss Blizzards and the defense increasing Aurora Veil.
Perfect coverage with Blizzard, Shadow Ball and Thunderbolt

Negatives
Special Defense really needs a Close Combat boost to comfortably endure Special Attacks.
Brave Bird’s recoil runs contrary to the defensive escalation of Snow Warning Close combat, making Mega far frailer than it would otherwise be.
Flying Fighting is exploitable defensively with numerous weaknesses

Timid Nature

Much like every other Snow Warning user that has it, Mega Froslass runs Blizzard and Aurora Veil for power and defensive utility. Blizzard is a house of a move being a base 110 STAB attack of the offensively potent Ice type, threatening the Dragon types that are endemic to many teams to say nothing of the many other Ice weak targets. To give a few examples, Mega Froslass threatens Yache Berry Garchomp, Mega Dragonite (through Multiscale), Mega Staraptor, Hippowdon, Hydreigon, Mega Meganium, and Mega Clefable with OHKOs, covering many of the most popular Mega Evolutions and staples that Mega Froslass handles. Aurora Veil conversely is pure defensive utility for Mega Froslass’ whole team, not only making Mega Froslass harder to remove, but its allies as well, greatly facilitating setup sweeps or surviving attacks they otherwise would not be able to. Shadow Ball is secondary STAB, but Ghost is a generally good offensive type with its wide neutral coverage and with Shadow Ball, Mega Metagross, Aegislash, Basculegion, Gholdengo and Mega Starmie cannot safely wall Mega Froslass’ Blizzard due to fear of the follow up Shadow Ball. Thunderbolt is tertiary coverage, namely for the Water types that resist Ice, but that still covers Water Dark types like Mega Gyarados and Hisuian-Samurott, as well as maiming Mega Charizard Y on top of the amazing synergy Electric has with Ice for near perfect coverage.

Stats and Items:
Max Speed and Special Attack are recommended. Even with the boosts from Aurora Veil and Snow, Mega Froslass’ bulk isn’t the best and one wants to hit hard and fast to compensate. Speed investment is especially paramount given Mega Froslass wants to throw an Aurora Veil up before getting hit. Thus full investment and Timid Nature are recommend for as wide a range a targets as possible. Dropping down to Modest still allows Mega Froslass to outrun up to base 103s like Garchomp, Mega Floette, Volcarona, Mega Dragonite, etc. Modest does leave Mega Froslass slower than Mega Metagross, one of the most popular Mega Evolutions available, to say nothing of Gengar, Mega Lucario, Hisuian-Zoroark, as well as no longer speed tie Jolly Sneasler or Mega Starmie. Full Special Attack investment is recommend simply for picking up as many OHKOs as possible. If going for a more supportive Mega Froslass set (or relying on Nasty Plot to make up the difference), sacrificing Special Attack for HP investment does wonders for increasing Mega Froslass’ staying power. For example 30 HP investment prevents Kingambit from OHKOing with a Black Glasses Sucker Punch, Modest Archaludon’s Flash Cannon and Modest Hydreigon’s Dark Pulse and 12 HP denies a OHKO from Dragapult’s Phantom Force. Item is locked to the Froslassite.

Partners:
Resists to Ice are big problems for Mega Froslass given its primary form of offense is to click Blizzard, and thus Pokémon that can handle the Fire, Steel and to a lesser extent Water types that trouble Mega Froslass are greatly appreciated. For Fire and Steel types, Garchomp immediately comes to mind, resisting the former and wielding wicked Ground STAB to handle most Fire and Steel types along with Stone Edge for Mega Charizard Y and Mega Delphox. Garchomp in turn loves Mega Froslass brutalizing Skarmory and Corviknight with Thunderbolt, two otherwise difficult walls for it as well as contest opposing Dragon types. Garchomp’s above average bulk also synergizes well with Aurora Veil for easy Swords Dance setup. Volcarona, while doing poorly against Fire types, is another excellent anti Steel ally and partial Dark check thanks to its Bug STAB. Mega Froslass in turn enables Volcarona by easing Quiver Dance setup and removing Dragon and Flying types that resist Volcarona’s STABs. For a more dedicated Fire type answer, Primarina stands out, thanks to its massive special bulk as well as Fairy subtyping handling most Dark types well. In turn, Mega Froslass threatens the Grass types that give Primarina trouble as well as being able to better soak up Poison coverage on top of providing a massive boost to Primarina’s already not inconsiderable bulk. Oddly enough, other weather setters like Hippowdon also make good partners for Mega Froslass. This is because if Mega Froslass is forced out, they can come in and change the weather, ensuring that when Mega Froslass comes back it, Snow Warning will reassert itself and give Mega Froslass the full timer again. Hippowdon is preferred among weather setters for its Ground STAB threatening most Steel and Fire types along with Stealth Rocks access to wear Fire types down. Yawn can also be used as an enabler for Nasty Plot sets, or to get Mega Froslass back in safely. Mega Froslass returns the favor being an excellent check into the Grass and Flying types that otherwise soak up Hippowdon’s Earthquakes with ease. Pelipper can also work, but it is generally underwhelming unless backing a dedicated Rain core.

Other Options:
Nasty Plot gives Mega Froslass absurd power even when uninvested, making it so even resists struggle switching into Blizzard, let alone Mega Froslass’ coverage. Destiny Bond can work with dedicated Aurora Veil sets allowing Mega Froslass to sacrifice itself after setting up Aurora Veil for an ally to take advantage of but is a heavy cost for a Mega Evolution. Taunt is great on any fast Pokémon for shutting down opposing setup and Mega Froslass is no exception. Will-O-Wisp is fantastic at crippling physical attackers, especially Tyranitar and Mega Metagross.

Doubles and VGC Options

Weather setters have always been a magnitude stronger in Doubles as opposed to Singles formats due to impacting every Pokémon on the field and Mega Froslass is no exception, though not for the traditional reasons. Snow only benefits Ice types, users of Weather Ball and Pokémon intending to spam Blizzard, but Ice’s many weaknesses makes it hard to stack multiple Ice types to take advantage. Instead, Mega Froslass’ Snow works as powerful Weather disruption, depriving opposing Weather teams of their Sun, Rain or Sand and greatly weakening them while empowering Mega Froslass. Mega Froslass as a Mega Evolution Weather setter is incredible, outslowing both opening and switching in base Drought, Drizzle and Sandstream users, making it incredibly reliable at getting the Snow setup. It doesn’t end there, as Mega Froslass’ favored moves in Blizzard and Aurora Veil too are stronger in Doubles, spreading around obscene damage quickly while actively making both Mega Froslass and its partner more durable. Mega Froslass is an incredibly reliable turn 1 Aurora Veil setter as well, thanks to its Ghost typing providing Fake Out immunity, making it difficult to deny Aurora Veil as well as hinder Mega Froslass in general. It is not all snow storms and auroras for Mega Froslass. Mega Charizard Y and (Mega) Tyranitar are even more popular in Doubles than in Singles for the same reasons as Mega Froslass and are lopsidedly favored to beat Mega Froslass and win the weather war due to their lower speed. Poor matchups into format superstars like Incineroar, Kingambit, Mega Metagross, Mega Mawile and more can make it difficult to bring Mega Froslass to every match, especially when it is little opportunity cost to field so many checks for Mega Froslass. Furthermore, while Mega Froslass’ utility is insane, much of what it can be do can be replicated by Alolan-Ninetails, whose ability to hold Light Clay and not taking up one’s Mega Evolution slot make it the preferred Aurora Veil setter in many, though not all scenarios.

Modest Nature

The standard Mega Froslass set you will see on most teams and for good reason, offering weather control, powerful spread damage and defensive utility all in one package. Blizzard is Mega Froslass' STAB of choice and an incredible one at that. High spread damage whose accuracy is fixed by the snow on one of the most offensively potent types in the game along with a game ending rider that has decent chance of going off due to multiple targets and the sheer number of times Mega Froslass will be using Blizzard. Blizzard's list of targets is quite extensive, including staples like Garchomp, Sinistcha, Whimsicott, Aerodactyl, Dragonite, Kommo-o, and Mega Staraptor, all lethal threats or potent support pieces that cannot handle the cold, especially the core of Whimsicott and Mega Staraptor, an otherwise difficult pairing. Aurora Veil is defensive utility, making Mega Froslass and its partners that much harder to remove, allowing Mega Froslass to freely fire off more Blizzards. Protect is the best move in Doubles, with endless utility, stalling out for allied setup, stalling out detrimental field conditions, scouting for moves, punishing double ups and more, Protect's value in Doubles formats cannot be understated. Shadow Ball is secondary STAB, and while lacking the supreme power of Blizzard, Ghost coverage is notoriously wide and allows Froslass to handle select Ice resistant targets in Aegislash, Metagross, Gholdengo and Basculegion, making it hard to drop.

Given Mega Froslass' ability to stack defense boosts, some defensive investment can have Mega Froslass quite difficult to remove. 12 HP and 1 Def ensures Adamant Kingambit's Sucker Punch can't OHKO while Blackglasses Kingambit only has a 50% chance to OHKO with the same, while Incineroar only has a 1/8 chance to OHKO with Flare Blitz. While Mega Froslass does sacrifice some speed by going Modest it still handily outruns Garchomp with max investment while the given stat points ensure that this Mega Froslass hits harder than a fully invested Timid Mega Froslass. Timid does allow Mega Froslass to outrun Jolly Mega Metagross and Mega Staraptor, potentially saving Mega Froslass from a lethal blow, but with Timid, Mega Froslass caps out at only a 1/16 chance to OHKO offensive Mega Metagross with Shadow Ball. Going Modest does make the OHKO more reliable, but not by much; the given spread is only a 25% chance to OHKO and Max Special Attack Modest is a 68% chance to OHKO.

Preferred Partners & Other Options:
Dedicated answers to Mega Charizard and Tyranitar are a must given how easily they shutdown Mega Froslass from the word go. Lycanroc-Dusk is the perfect silver bullet for both. With Rock STAB Lycanroc-Dusk easily OHKO’s Mega Charizard Y with both Rock Slide and Accelerock, preventing both redirection and Wide Guard from saving Mega Charizard Y, while Tough Claws Close Combat one shots even Max HP/Defense Impish Mega Tyranitar. Garchomp is also decent at this role thanks to access to Rock Slide/Stone Edge and Ground STAB while resisting both Mega Charizard Y’s brutal Fire STABs and Tyranitar’s own Rock Slides and Stone Edges. Kingambit is notable for being a soft deterrent for many of Mega Froslass’ checks, with Defiant discouraging Incineroar, Steel typing threatening Tyranitar and Wide Guard Aerodactyl, and Dark STAB for Mega Metagross and Basculegion while being a huge beneficiary of Aurora Veil. Whimsicott is another enabler of Mega Froslass, given Tailwind allowing Modest Mega Froslass to once again outrun Mega Metagross as well as nominally faster Pokémon like Mega Delphox, (Mega) Aerodactyl, and Mega Gengar turning would be checks into much easier matchups. Access to Fake Tears also helps matters, as in conjunction with Blizzard or Shadow ball can consign a target to a quick knockout. Rain Dance is odd given how reliant Mega Froslass relies on Snow, but allows her to act as a lure for Mega Charizard Y, Torkoal and to a lesser extent Tyranitar, depriving them of their weather, and weakening the Fire STABs sent Mega Froslass’ way. Weather Ball works great both with Rain Dance to cleanly remove Mega Charizard Y, and Tyranitar as well as in general, giving Mega Froslass an Ice STAB attack that is not blocked by Wide Guard. Thunderbolt removes Pelipper and Politoed, preventing Rain teams from being as big of an issue. Nasty Plot is just as effective, allowing Mega Froslass to more heavily focus on defensive investment, while possessing game ending power once setup.

Countering Mega Froslass

Between weather control, Aurora Veil and sheer power, Mega Froslass can easily warp the course of a battle around itself, but is held back by lacking defenses and an easily exploitable type combination.

First and foremost, weather disruption messes with Mega Froslass even more than other weather setters. Outside of the Snow, Aurora Veil cannot be activated and Blizzard becomes as reliable as Focus Blast. Mega Charizard Y and Mega Tyranitar are the best at this, given they can Mega Evolve at the same time as Mega Froslass and outright deny Snow and thus Aurora Veil while boasting good special bulk to be able to stomach a Blizzard and super effective STABs to drop Mega Froslass quickly. Torkoal, Politoed, Pelipper, and Hippowdon can also fulfill this role, but the latter two do not resist Blizzard and all of them due to not being Mega Evolutions must have Mega Froslass establish the Snow before coming in.

Faster attackers are otherwise highly advised to deal with Mega Froslass, as giving it a free turn to setup Aurora Veil makes Mega Froslass and its teammates much more difficult to remove to the point of deciding a match. Life Orb Greninja, Mega Delphox, Mega Gengar, Scarf Hydreigon, Scarf Gholdengo, Mega Lopunny, and Scarf Rotom-Heat, and Scarf Glimmora are all capable of outrunning and OHKOing Mega Froslass.

As for defensive checks, it is generally advised never to let Mega Froslass get a Nasty Plot off. At +2 Special Attack even an uninvested Mega Froslass can 2HKO every available Pokémon with Blizzard, Shadow Ball or Thunderbolt. Unaware Clefable is best in such a scenario as 2 SAtk Mega Froslass only has a 32% chance to 2HKO when Clefable is 32 HP/2 SDef, meaning Clefable can try to outlast Mega Froslass with Calm Mind and Moonlight, though the latter being weakened by Snow Warning does not help matters. Kingambit is notable for surviving even a +2 Thunderbolt (taking 49-58%) and able to OHKO back with Blackglasses Kowtow Kleave. Volcarona can survive a +2 Shadow Ball, taking only 72-85% and able to Quiver Dance and OHKO back with Fiery Dance. Max HP Scizor takes 81-95% from +2 Shadow Ball, but thanks to Bullet Punch, it out prioritizes Mega Froslass and comfortably 2HKOs while Mega Scizor does even better.

Mega Froslass does struggle to fit Thunderbolt onto its set, and is often forced to drop it, opening more checks. Mega Gyarados easily absorbs both +2 Shadow Ball and Blizzard capping out at 45-54% depending on Timid Mega Froslass’ Special Attack investment, while Crunch has a 5/8 chance to OHKO offensive Mega Froslass and after a Dragon Dance even defensive Mega Froslass will be one shot. Hisuian-Samurott can survive a +2 Blizzard from Timid Froslass while having a 25% chance to OHKO with Ceaseless Edge and can secure it with Aqua Jet.

If Mega Froslass is not running Nasty Plot, checks greatly expand. Ice resists are valued for their ability to soak up Blizzards. Mega Metagross with 4 HP investment cannot be OHKO’d by Timid Mega Froslass’ Shadow Ball and solidly OHKOs through Snow with Tough Claws Iron Head or 2HKOs with Snow+Aurora Veil. Mega Blaziken outspeeds Mega Froslass after a Speed Boost and can OHKO with Flare Blitz and will even survive Flare Blitz recoil + a 32 Special Attack Shadow Ball. If lacking Thunderbolt, Max HP Primarina takes at most 40-44% from Shadow Ball and can use Mega Froslass to setup Calm Minds. Max HP Mega Mawile still takes a whopping 47-56% from Timid Shadow Ball, but OHKOs with Iron Head, and does 78-92% to Mega Froslass through Snow and Aurora Veil and can easily KO with the follow up Sucker Punch.
