Our memories will remain
Snorlax's excellent special bulk and a lone weakness to Fighting make it difficult to KO without relying on dedicated Fighting-types or extremely powerful physical attackers. This alllows Snorlax to blanket check a number of dangerous threats, such as Tapu Lele, Naganadel, Greninja, and Volcarona, as well as reliably checking rain attackers like Kingdra, and with heavy investment on Defense, Mega Swampert. On top of this, Snorlax can utilize Gluttony, a pinch berry, and Recycle to give itself an access to a consistent recovery, which not only further improves Snorlax's defensive capabilities but also lets it punish many foes by setting up Curse. All of these factors combine Snorlax a problematic Pokemon to deal with for many teams, especially if they lack a way to immediately threaten it. However, Snorlax tends to struggle with physical attackers even with investment on Defense due to lack of resistances. This means setting up Curse can be somewhat difficult in the metagame filled with physical attackers, among which majority of them are capable of overwhelming Snorlax thanks to setup moves, Z-Moves, or both. Abysmal Speed can also be a detrimental factor for Snorlax, as it will be vulnerable to all variations of status moves, particularly Taunt.
move 1: Whirlwind
move 2: Yawn
move 3: Recycle
move 4: Heavy Slam / Earthquake
item: Iapapa Berry
evs: 28 Atk / 252 Def / 228 SpD
Snorlax can reliably shuffle foes with Whirlwind and rack up damage when Stealth Rock is up. Yawn is another move that often forces a foe to switch out by discouraging a foe from staying and falling asleep next turn. It is also useful with preventing Snorlax's team from losing momentum in an event where a foe that offensively checks Snorlax switches in and potentially letting Snorlax provide a safe setup condition for one of its teammates. Recycle in tandem with Wiki Berry and Gluttony lets Snorlax recover itself and remain longer as an annoyance for opposing team. The fourth move should be an attacking move to prevent Snorlax from being completely passive. Heavy Slam is typically the best option, as no foes are immune to it and the move does heavy damage to Fairy-types and frail foes like Mega Gengar. Earthquake is an alternative option that can notably OHKO a problematic Heatran and can still 2HKO Mega Gengar and Tapu Koko.
28 Attack EVs allow Snorlax to, with Stealth Rock on the field, OHKO Tapu Lele and Mimikyu and 2HKO Tapu Koko and bulky Mega Gengar with Heavy Slam, letting Snorlax from taking too much damage on punish them should they attempt to cripple Snorlax with Taunt. The rest of the EVs are invested on Defense and Special Defense to maximize Snorlax's overall bulk with Impish nature, and investment on HP isn't necessary due to Snorlax already possessing an enormous HP stat. Investing on both sides of defense aids Snorlax from taking hits, notably letting it avoid 2HKO from Modest Tapu Lele's Psychic and any attack from Choice Specs Kingdra in rain. Gluttony makes Snorlax consume its berry after Snorlax loses more than half of its HP, and Iapapa Berry heals Snorlax's health by 50%. Aguav Berry or Figi Berry are alternatives to bypass item clause, if one of Snorlax's teammates is already holding Iapapa Berry.
Thanks to its sheer bulk, Snorlax can continuously rack up damage on foes when Stealth Rock is up, by forcing switches with Whirlwind and Yawn, while keeping itself healthy with Recycle. Phazing a foe with Whirlwind is a good idea when a foe is going to switch into Snorlax's offensive checks or attempt to set up on it. Otherwise, Yawn is usually a good move to use, as a foe is forced into either switching out and making the switch-in take the damage from Stealth Rock, or having one of its Pokemon fall asleep. Repeatedly using Yawn against bulkier teams is typically the best option, as this eventually forces one of the foes to be put to sleep, letting Snorlax take advantage of them to phaze foes more reliably or giving a safe switch-in to one of its teammates that can take advantage of a foe put to sleep. Although a combination of Whirlwind and Yawn usually prevents Snorlax from being used as a setup fodder, be wary of Substitute users like Mega Salamence, Mega Gyarados, as they can use Snorlax as a setup fodder if they are the last Pokemon in the team and are behind Substitute. Substitute variants of Celesteela and Gliscor can pose problems to Snorlax in the same regard. Lastly, be very wary of foes that are capable of removing Snorlax's Iapapa Berry, as foes that use moves like Knock Off or Trick can outright shut down Snorlax by preventing it from recovering. This means Snorlax must be wary of Rotom's Trick and face the likes of Landorus-T, Ferrothorn, and Mega Mawile with caution. Status moves, while not devastating as item removal, should also be avoided, as poison greatly reduces Snorlax's longevity, while burn leaves it very passive.
A physically durable Stealth Rock user pairs the best with this variant of Snorlax, as Snorlax can take advantage of said entry hazard to rack up damage by phasing foes and handle special attackers in return. Landorus-T and Skarmory are excellent choices in this regard. Landorus-T, while it lacks a reliable recovery, can handle Steel-types and Ground-types, which are quite hard to wear down with Stealth Rock damage. It also handles Heatran, which is very problematic for Snorlax to deal with due to it typically carrying Toxic or Taunt. Skarmory, on the other hand, can switch into Toxic for Snorlax, blanket check strong physical attackers like Mega Salamence and Landorus-T, while it can also phaze foes itself. A bulky, strong teammate is recommended as well to ensure that the last foe, which cannot be phazed, is reliably dealt with. Mega Salamence and Mega Gyarados are excellent choices, as they can switch into predicted Fighting-type moves for Snorlax and vastly appreciates having their checks being put to sleep or worn down by Stealth Rock. Mega Blaziken, while it is not bulky, it can take threaten problematic foes like Celesteela, Ferrothorn, and Heatran. Dealing with the former two are especially important, as Leech Seed makes Snorlax's phazing Stealth Rock much less effective. Mega Blaziken also is notable for being capable of turning itself into a fearsome cleaner after a turn of set up, which can be easily done if Snorlax put a foe to sleep. Priority users are also feasible choices to deal with the last foe. Mimikyu is a fantastic check to Fighitng-types, or essentially most setup sweepers that can overwhelm Snorlax, and also appreciates the prior damage dealt on various foes, which aids its cleaning late-game. Greninja can quickly dispose of offensive foes like Landorus-T or Mega Blaziken, both of which are capable of overpowering Snorlax and its common teammate if using Swords Dance.
move 1: Curse
move 2: Recycle
move 3: Return
move 4: Earthquake / Fire Punch
item: Iapapa Berry
evs: 148 HP / 12 Atk / 252 Def / 92 SpD / 4 Spe
Curse improves both Snorlax's damage output and bulk, and improving its Defense is especially important, as setting up multiple Curses helps Snorlax overcome one of its defensive shortcomings. Recycle in tandem with Gluttony and Iapapa Berry provides Snorlax with a reliable recovery. Return is a consistent STAB move that becomes progressively more dangerous as Snorlax accumulates boosts from Curse. Earthquake hits various foes that resist return super effectively, such as Heatran, Aegislash, Mega Metagross, and Tyranitar and serves as the quickest way to dispose of Mega Blaziken, Naganadel, and Mega Lucario after a Curse. Fire Punch, while it has worse coverage overall, still hits many Steel-types super effectively, and notably does heavy damage to Ferrothorn, Mega Scizor, and Kartana. It also hits Celesteela hard unlike Earthquake.
The EV spread is focused on improving Snorlax's physical bulk as much as possible, as Snorlax isn't physically durable until it manages to set up multiple Curses, and heavy investment on Defense is needed to maximize Curse's efficiency. While making such investment, appropriate distribution of EVs to other stats and a choice of Adamant nature are applied for Snorlax to meet a number of important benchmarks against extremely common threats. 148 HP, 252 Defense, and 92 Special Defense allow Snorlax to survive +1 Adamant Mega Salamence's Double-Edge, avoid 2HKO from Modest Tapu Lele's Psychic and Outrage from Garchomp, while surviving Jolly Blaziken's High Jump Kick most of the time, if it would end up proving to be a necessity. The rest of the EVs are put into Attack and along with Adamant nature, it amplifies Snorlax's damage output to a degree. Gluttony and Iapapa Berry are mandatory to keep Snorlax healthy and let reliably set up Curse on foes that it isn't threatened too much against. Other pinch berries like Aguav Berry or Figi Berry can be used to get around Item Clause.
This variant of Snorlax aims to take advantage of a bulky foe that can't effectively combat Snorlax by setting up multiple Curses on them to the point where Snorlax becomes nigh impossible to surmount and gains enough offensive presence to make a sweep of its own. Snorlax can easily set up on common Pokemon like Porygon2 and Celesteela and repeat a combination of Recycle and Curse to the point where Snorlax can overpower them with boosted attacks. Although setting up with this set may seemingly be simple, always be cautious about any Pokemon that may carry status moves, such as Heatran, Cresselia, and Zapdos. Although Snorlax can easily take any hits from them, said foes tend to carry Toxic, or even Taunt in the former's case, and this prevents Snorlax from effectively fulfilling its role. Potential users of Knock Off and Trick, namely all Landorus-T, Ferrothorn, Mega Mawile, and all Rotom forms should also be scouted beforehand so that Snorlax won't lose its Iapapa Berry and be left unable to recover itself. Although less of an issue, potential OHKO move users like Gliscor or Mamoswine and Perish Song users like Politoed must be viewed with caution as well.
Landorus-T is the best partner for Snorlax and it can aid Snorlax in a variety of ways. Almost every variant of Landorus-T can viably run Stealth Rock to ensure that Focus Sash users can't recklessly take on boosted Snorlax. Both defensive and Assault Vest variants of Landorus-T can safely bring in Snorlax into a favorable matchup so that it can easily set up Curse. Swords Dance variants can take care of problematic defensive Pokemon like Gliscor, Hippowdon, and Tapu Fini, by OHKOing them all with boosted Supersonic Skystrike. Landorus-T's ability to naturally threaten troublesome foes like Mega Gengar and Heatran and switch into Fighting-type moves for Snorlax are appreciated as well. Tapu Fini is another fantastic partner, as Misty Terrain prevents Snorlax from getting crippled by status ailments. On top of being able to handle physical attackers like Mega Salamnce and Mega Blaziken that would overwhelm Snorlax, Tapu Fini can wear down various foes with Nature's madness, or, if running an offensive set, can even lure and eliminate wall like Porygon2 and Ferrothorn. Tapu Lele, while it is not defensively capable of checking Fighting-types, can still massively threaten them and can potentially provide Snorlax a reliable condition to set up Curse by afflicting a foe with Taunt before it is KOed. Heatran can switch into various status moves for Snorlax, and can spread status ailments itself, meaning it can put a problematic foe on a timer with Toxic or spread burn to make physical attackers struggle even more with Snorlax as it sets up Curse. As Snorlax can take on essentially any offensive foe that lack setup options or can heavily damage Snorlax, any teammates that can alleviate Snorlax's vulnerability to status ailments and can handle Fighting-types are generally good fits.
Fissure on phazing set can let Snorlax occasionally outright KO a problematic foe, but inconsistency leaves this generally an inferior option. Facade on Curse can be used to abuse status, but if a foe would status Snorlax, they would most likely afflict it with a Toxic poison to make Snorlax eventually succumb to a residual damage, and this leaves Return a far more desireable STAB move due to its consistency. Double-Edge has better damage output than Return, but it is somewhat counterproductive to Snorlax's tendency to take consistently take hits and set up Curse. Snorlax has an access to other useful abilities like Immunity, which helps with Snorlax's one of the greatest annoyances by granting it an immunity to poison status, or Thick Fat, which significantly improves Snorlax's ability to check Fire- and Ice-types. These abilities may make defensive sets like Assault Vest plausible options, but there are many Pokemon in the metagame that can blanket check a significant larger array of threats, and the fact that Mega Blaziken is the most common Fire-type Pokemon in the metagame that possesses a Fighting typing makes Snorlax a disappointing check for Fire-types.
Checks and Counters
**Fighting-types and Fighting-type moves**: Fighting-types are capable of bypassing Snorlax's enormous bulk by exploiting its weakness to Fighting-type attacks. If they would not outright OHKO it, most Fighting-type attacks are capable of weakening Snorlax to the point where it will no longer be effective. Mega Blaziken, Mega Lucario, and Pheromosa are terrifying threats to Snorlax in this regard, but none of them can safely switch into Snorlax and they do not appreciate switching into Yawn either, as they are forced to switch out or fall asleep next turn. Pokemon that may carry a Fighting-type move as an coverage option, such as Tapu Bulu, Mega Metagross, and Kartana can threaten to heavily damage Snorlax. Kartana in particular is more threatening due to its ability to take a few Earthquakes and hit Snorlax through Curse boosts with Sacred Sword. However, the former two may struggle bypassing a healthy Snorlax, as in some instances, Snorlax's Iapapa Berry may prevent a 2HKO.
**Ghost-types**: Though Snorlax typically prepares for Ghost-types by employing moves like Heavy Slam or Earthquake, Ghost-types like Mega Gengar, Mimikyu, and Aegislash are notable threats to Snorlax for different reasons, aside from being immune to Snorlax's STAB Return. Mega Gengar can trap and cripple Snorlax with Taunt or Will-O-Wisp, force its removal with a well-timed use of Destiny Bond, or stall Snorlax and remove it with Perish Song should it lack a reliable way to threaten Mega Gengar. Mimikyu, although it dislikes offensively taking on Snorlax with Curse, is still capable of removing Snorlax with a boosted Let's Snuggle Forever. Variants with Will-O-Wisp, Taunt, or even Destiny Bond prove to be an annoyance for Snorlax as well. Aegislash, if running a defensive set, can put Snorlax on a timer with Toxic and can easily stall out Curse sets with a combination of King's Shield and Substitute. Offensive variants with Weakness Policy can rather take advantage of Curse Snorlax as long as it hasn't been excessively boosted beforehand, as Aegislash can easily survive an Earthquake retaliate the next turn with a boosted Sacred Sword.
**Item Removal**: Without Iapapa Berry, Snorlax is no longer able to utilize its high bulk and fulfill its role efficiently. Therefore, it must play extremely cautious against potential users of Knock Off or Trick, such as Landorus-T, Mega Scizor, Kartana, and all Rotom formes.
**Wallbreakers**: Due to Snorlax's tendency to avoid potential KOs with a combination of Recycle and Iapapa Berry, boosted attacks or wallbreakers often pose a problem to it. Users of Swords Dance or Nasty Plot like Mimikyu and Garchomp for the former and Naganadel and Thundurus-T for the latter can KO Snorlax with a boosted Z-Move with or without prior damage.
**Taunt**: Snorlax largely relies on its utility options to fulfill its roles and stay healthy, and due to this, it is vulnerable to Taunt users like Tapu Koko, Tapu Lele, and Mega Gengar. However, most of them are prone to getting 2HKOd by common Snorlax variants.
**Status**: Snorlax's extremely low Speed leaves it vulnerable to all kind of status moves even from many status inducers that are slow by the metagame's standards. Toxic puts Snorlax on a timer, while a burn induced by Will-O-Wisp, Scald, or Lava Plume neuters Snorlax's damage putout and forces Curse variants to fully set up to do a notable damage to foes. Snorlax is also vulnerable to Breloom's Spore as well.
