Eternatus Movesets & Competitive Sets

With amazing stats, strong attacks, utility moves, and a useful defensive typing, Eternatus can be the cornerstone of a difficult-to-break defensive team without entirely sacrificing a team's offensive presence. Even uninvested, its base 145 Special Attack provides meaningful damage when paired with STAB moves. Toxic Spikes provide an advantage to Eternatus's team by limiting a lot of defensive counterplay to its offensive teammates or necessitating turns spent removing the entry hazard, while Recover allows it to extend its longevity significantly. The EVs maximize Eternatus's ability to move ahead of most Pokemon without a Speed donation. HP is maximized to avoid problems with Stealth Rock after Knock Off, allowing Eternatus to reliably take hits on both sides of the damage binary without necessarily specializing in one or the other. The remaining EVs are put in Special Attack to increase damage ever so slightly. Heavy-Duty Boots and Tera Ghost serve much of the same defensive purpose, with the former allowing Eternatus to reliably switch in and out without worrying about entry hazards and the latter allowing it to change its defensive profile while preventing Rapid Spin from removing its Toxic Spikes. Black Sludge and Toxic are not joined at the hip in the same way; the former allows Eternatus to stay in for longer, while the latter provides a more direct way for Eternatus to disrupt foes. Eternatus should be placed in the Attack slot and paired with Pokemon that can enable a more defensive playstyle while retaining one or two options for more aggressive plays. Defensive Pokemon like Zamazenta, Rotom-Wash, and Skarmory appreciate an HP donation, while Hydrapple, Gholdengo, and even Urshifu-R appreciate Eternatus's great Speed. Base 95 in Defense and Special Defense is average compared to other gods; however, it can be used by Pokemon such as Clefable and Great Tusk to shore up a weaker defensive stat. Pokemon that can get Eternatus in safely via pivoting, such as Rotom-Wash and Corviknight, reduce the amount that Eternatus needs to heal throughout the game. Gholdengo stops removal of Toxic Spikes entirely, though Ground-types can put pressure on absorbers of Toxic Spikes, ensuring Eternatus doesn't waste turns setting them up. Finally, Steel-types serve as a major roadblock to Eternatus's ability to deal damage, so teammates like both Landorus formes and the Urshifu formes can provide additional damage output while covering that deficiency, while Electric-types can handle Skarmory and Corviknight.

Offensive Eternatus leverages its amazing Special Attack and Speed to form devastating offensive cores with the receivers of those two stats. After boosting its Special Attack with Meteor Beam, Eternatus can tear through weakened teams with its strong STAB combination and good coverage. Dynamax Cannon is a reliable STAB move that will deal great damage to most neutral targets. Sludge Bomb hits Fairy-types such as Clefable, Primarina, and Arceus-Fairy, which are immune to Dynamax Cannon. Fire Blast is super effective against Steel-types like Necrozma-DM, Excadrill, and Iron Treads, which resist Eternatus's STAB moves. Meteor Beam offers super effective coverage against various Fire- and Flying-types and gives Eternatus a power boost for the rest of its moves. Tera Dragon allows Eternatus to survive Earthquake from the likes of defensive Great Tusk and defensive Landorus-T and boosts the power of Dynamax Cannon, allowing it to OHKO the Urshifu formes and 2HKO offensive Great Tusk that received a base Special Defense stat up to 130 at +0. Alternatively, Tera Fire allows Fire Blast to OHKO the aforementioned Steel-types after a Meteor Beam boost. A set with Life Orb and Recover over Meteor Beam offers Eternatus more longevity compared to Power Herb sets. Power Herb sets, however, allow Eternatus to use Meteor Beam immediately without taking damage from Life Orb, but Eternatus can only do this once before switching out. Eternatus has one of the highest Speed stats of any god in the metagame, making it a great donor for receivers like Urshifu-S and Landorus-T, which all give special walls a hard time. Eternatus also possesses exceptional Special Attack, which is great for fast attackers like Hisuian Electrode and Greninja or setup sweepers like Nasty Plot Landorus and Calm Mind Comfey, which, in tandem with Eternatus, can overwhelm special walls. Eternatus also possesses a massive HP stat, which can be utilized to great effect by defensive teammates like Rotom-W, Skarmory, and Sinistcha. Setup sweepers like Iron Defense Zamazenta, Calm Mind Iron Crown, and Nasty Plot Darkrai can also use the extra HP to set up more easily. Eternatus struggles to break through walls that can weather its STAB moves and don't care about Fire Blast such as Ting-Lu, Heatran, and Assault Vest Galarian Slowking, so teammates that pressure these Pokemon like Ogerpon-W, as well as the aforementioned Landorus-T and Urshifu-S, are extremely appreciated. Finally, Eternatus appreciates entry hazards from the likes of Great Tusk, Skarmory, and Landorus-T to help it get KOs more easily.

Life Orb Eternatus is one of the strongest special wallbreakers in the metagame, taking advantage of its incredible damage output and movepool to punish defensive staples such as Milotic, Magearna, and Pecharunt. Fire Blast is its strongest option against Steel-types like Magearna and Iron Crown, though it can instead opt to run the weaker but more accurate alternative in Flamethrower. Recover helps Eternatus mitigate Life Orb chip damage, improving its longevity. Eternatus fits well on bulky offense and balance archetypes. It synergizes extremely well with other offensive pieces like Urshifu-R, Zamazenta, and Spectrier, forming deadly offensive cores that can overwhelm common defensive foes like Magearna, Pecharunt, and Arceus formes. Eternatus appreciates entry hazard setters to aid it in wallbreaking, making Pokemon like Magearna, Hisuian Samurott, and Great Tusk stellar teammates, as even a single layer of Spikes can let Dynamax Cannon 2HKO bulky targets like Arceus-Ground. Eternatus gets worn down fairly easily by Life Orb recoil and hazards, so it heavily appreciates teammates that remove hazards such as Regieleki and the aforementioned Great Tusk as well as Sablenite users like Garganacl and Milotic. Arceus formes like Arceus-Ghost, Arceus-Fairy, and Arceus-Water also make excellent partners, helping to handle potential revenge killers such as Iron Crown and Extreme Speed users while posing major threats themselves with Calm Mind.

Eternatus is a premier defensive staple in the tier due to its solid typing, excellent bulk, and useful utility options. It consistently checks prominent Extreme Speed users, including Altarianite Regieleki, Dragonite, Hisuian Arcanine, and Entei, as well as other physical wallbreakers like Urshifu-R and Zamazenta. Both its STAB moves, Sludge Bomb and Dynamax Cannon, are highly spammable and devastating; the former, in particular, threatens Altarianite users and applies pressure to defensive foes with its high poison chance. Eternatus uses Flamethrower to avoid being completely walled by Steel-types like Magearna, Corviknight, Kingambit, and Aggronite or Rusted Sword Zamazenta. It can also choose Toxic over one of its STAB moves to immediately pressure defensive threats and setup sweepers like various Arceus formes, Ho-Oh, and non-Sablenite variants of Garganacl, Alomomola, and Mandibuzz. Alternatively, Toxic Spikes helps spread poison on foes and limits common VoltTurn cores such as Urshifu-R + Raging Bolt; however, it is heavily countered by Magic Bounce users. Rocky Helmet is the preferred item for punishing most physical attackers, especially Urshifu-R when it uses Surging Strikes. Heavy-Duty Boots is a reasonable choice to prevent entry hazard chip damage on Eternatus, while Black Sludge offers some passive recovery. The Speed EVs enable Eternatus to outspeed Hearthflame Mask Great Tusk and bulky variants of the Arceus formes. Eternatus fits well on bulky offense and balance teams. Specially defensive partners like Magearna, Ho-Oh, and Garganacl create strong cores with Eternatus; Magearna benefits from its ability to check Fire-types like Entei and Hisuian Arcanine, while Ho-Oh and Garganacl rely on it to handle Urshifu-R. Non-Heavy-Duty Boots variants are susceptible to hazards and greatly benefit from hazard removers like Great Tusk, Regieleki, Mandibuzz, and Corviknight. Hazard setters like Garganacl, Magearna, Clodsire, and Great Tusk, combined with Eternatus's own chip damage, effectively wear down multiple threats such as Urshifu-R, Hisuian Arcanine, Zamazenta, and the Arceus formes. Ground-type checks, such as Ho-Oh, Arceus-Water, and Milotic, are valuable teammates for covering one of Eternatus's biggest weaknesses. Ho-Oh can also threaten Magearna, which is one of Eternatus's biggest checks. Eternatus pairs well with teammates such as Urshifu-R, Raging Bolt, and Zamazenta by providing them with free switches against Pixilate Extreme Speed users.

Eternatus is an excellent blanket check to Kyogre, defensive Ho-Oh, Arceus-Water, and Arceus-Fairy that pressures opposing teams with Toxic Spikes and Toxic. Toxic Spikes is one of Eternatus's greatest assets, as it weakens the opposing defensive core and especially overwhelms hyper offense teams because it quickly chips down their sweepers due to them not having a way to remove it. Fire Blast or Flamethrower can be used instead to threaten Steel-types such as Zacian-C, Necrozma-DM, and Kingambit, with the former guaranteeing a 2HKO on Zacian-C and having a chance to OHKO it in sun and the latter providing more consistent damage at the cost of reduced firepower. However, this means dropping Toxic Spikes, which makes spreading poison much more difficult. Dynamax Cannon is Eternatus's preferred STAB move, but Draco Meteor can be run instead, trading consistency for the ability to OHKO both Koraidon and Miraidon. The given EV spread allows Eternatus to outspeed maximum Speed Kyogre and survive offensive Arceus-Ground's Earthquake from full HP. Tera Fairy allows Eternatus it to block Miraidon's Draco Meteor and Koraidon's Scale Shot or Outrage in an emergency but makes it more vulnerable to Steel-type attacks from Zacian-C and Kingambit and Flare Blitz from Koraidon. Tera Steel gives it valuable resistances to Kyogre's Ice Beam, Calyrex-I's Glacial Lance, Arceus's Extreme Speed, Arceus-Fairy's Judgment, and Psychic-type moves from Calyrex-S. Although, using Tera Steel makes Eternatus weak to Fire-type attacks such as Flare Blitz and Sacred Fire from Koraidon and Ho-Oh, respectively, as well as Koraidon's Low Kick and Zacian-C's Close Combat. Tera Dark is another option, albeit niche, that may be used to improve a team's matchup against Calyrex-S, but it makes Eternatus weak to Arceus-Fairy's Judgment and Koraidon's Low Kick. All three Tera types also reduce Eternatus's ability to check Kyogre and Ho-Oh, so the user must be wary before committing to Terastallizing. Eternatus fits on more passive balance and bulky offense teams that appreciate its ability to act as both a Toxic Spikes absorber and spreader that can take on threats like Kyogre, Ho-Oh, Arceus-Water, and Arceus-Fairy. Koraidon and Miraidon are both excellent partners, as the former can threaten Steel-type Pokemon, and the latter helps to break bulky Ground-types such as Ting-Lu and Arceus-Ground. In return, Eternatus helps check Kyogre and puts their checks, such as bulky Arceus formes and Ting-Lu, on a timer with poison. They both also appreciate Eternatus's ability to soak up status effects, and Koraidon in particular enjoys Eternatus reliably switching into defensive Arceus formes like Arceus-Fairy and Ho-Oh. Eternatus is vulnerable to Koraidon and Miraidon, which force it out with strong Dragon-type attacks, so Pokemon that can check them such as Ho-Oh, Arceus-Fairy, and Ting-Lu also make good teammates. Ting-Lu also helps Eternatus by switching into Calyrex-S, which can deal massive damage to Eternatus with its Psychic-type moves or lock it into Toxic Spikes or Recover via Encore. If Eternatus isn't running Fire Blast or Flamethrower, it is incapable of hitting Steel-types like Zacian-C, Necrozma-DM, and Kingambit, so Ground-types that force them out like Arceus-Ground and Landorus-T are also recommended. Arceus-Water can check the aforementioned Steel-types and Koraidon, as well as switching into Calyrex-I, Arceus-Ground, and Extreme Killer Arceus. Arceus helps to check Calyrex-S and benefits from Eternatus weakening the opposing defensive structure so it can clean up late-game. Eternatus also struggles with Hatterene, as it blocks Toxic and Toxic Spikes and is immune to Dynamax Cannon, so Pokemon that can beat Hatterene like Ho-Oh and Arceus-Ground are appreciated. Although, Fire Blast under sun can 2HKO Hatterene. Setup sweepers like Scale Shot Koraidon, Dragon Dance Arceus-Ground, and Swords Dance Zacian-C can easily force Eternatus out and set up on it, so reliable checks to them like defensive Arceus-Fairy and Arceus-Water are recommended.

Life Orb Eternatus is a niche offensive variant that trades its longevity and ability to soft check foes like Marshadow and Primal Kyogre to instead enhance its offensive capabilities. Its biggest draw lies in the immediate and dependable power boost granted to its attacks, allowing Eternatus to wallbreak multiple times throughout a game without relying on the two-turn nature of Meteor Beam. Its ability to harass bulky structures while also sporting a decent matchup against hyper offense makes it a worthwhile addition to balance and bulky offense teams alike. Dynamax Cannon is Eternatus’s STAB move of choice, with consistent damage output to net crucial 2HKOs against many defensive targets. This allows Eternatus to pressure foes such as Primal Groudon, Yveltal, and Zygarde; after one layer of Spikes, opposing Eternatus and support Arceus formes are brought into OHKO and 2HKO range respectively. Sludge Bomb threatens Arceus-Fairy with major damage while crippling targets with its valuable poison chance, making switch-ins such as Ho-Oh unable to stave off repeated blows long-term. If such targets are well-handled by its teammates, Toxic Spikes can instead be used to punish switches by setting grounded threats like Lunala, Primal Groudon, and Primal Kyogre on a timer. Fire Blast decimates Steel-types attempting to switch into its STAB moves, notably OHKOing Zacian-C and 2HKOing defensive Necrozma-DM after a layer of Spikes, while blasting apart Ferrothorn without the need for entry hazards. Recover takes advantage of forced switches to reliably heal Eternatus from chip damage and Life Orb recoil, allowing it to switch out and remain healthy enough to wallbreak at a later point in the match. Tera Dragon launches Dynamax Cannon to new heights, letting Eternatus 2HKO Ho-Oh, Primal Kyogre, and Tera Water or Poison Zygarde as well as OHKOing most offensive Primal Groudon variants after Stealth Rock. Tera Dragon secondarily sheds crucial weaknesses to Ground and Psychic, allowing Eternatus to take on threats such as Arceus-Ground, Primal Groudon, and an unboosted Ultra Necrozma at the cost of becoming vulnerable to Toxic. Tera Fire is an alternative that boosts its coverage, letting Eternatus more easily dispatch Zacian-C and offensive Necrozma-DM with a nuclear Fire Blast. Defensively, Tera Fire improves the matchup against Fairy- and Ice-types, allowing Eternatus to better check a boosted Arceus-Fairy and Choice-locked Chien-Pao as well as dodging Sacred Fire burns from Ho-Oh in a pinch, at the expense of a newfound weakness to Stealth Rock. Eternatus functions well as an early- to mid-game wallbreaker as well as a cleaner owing to its excellent Speed and offensive presence. However, its inability to safely switch into Poltergeist and Knock Off users in addition to demanding careful HP management due to Life Orb recoil means Eternatus appreciates pivoting support from offensive and defensive allies alike to find opportunities to safely enter the battle; therefore, Pokemon such as Yveltal, Mega Latios, and Alomomola synergize well with it. Eternatus appreciates allies that can set hazards to facilitate its wallbreaking, making teammates such as Primal Groudon, Arceus-Water, and Ferrothorn excellent partners; the former two pressure Defoggers like Ho-Oh and Yveltal with the threat of status moves and super effective coverage, while the latter punishes support Arceus formes and Giratina-O with Leech Seed. This set struggles against stall teams due to its low-PP moves as well as Life Orb recoil inevitably forfeiting momentum to use Recover, so teammates such as Choice Band Rayquaza and Overheat Primal Groudon help Eternatus in overwhelming special walls like Chansey and Ho-Oh, while Eternatus threatens Dondozo and Arceus-Dark in return. Rayquaza is a particularly useful ally due to its access to U-turn, allowing Eternatus to safely enter the field and wreak havoc.

Defensive Eternatus stands out as a top-tier defensive staple, as it is able to completely wall Arceus-Dark, is immune to Toxic, and can simultaneously serve as one of the few Knock Off absorbers in the tier. Its Speed tier allows it to outpace Arceus formes and Marshadow while maintaining enough bulk to withstand hits and provide a soft check against threats like Ho-Oh and Primal Kyogre. Moreover, Pressure enables Eternatus to PP stall moves like Water Spout from Primal Kyogre, Judgment from Arceus-Fairy, Sacred Fire and Defog from Ho-Oh, and Dynamax Cannon from opposing Eternatus. Finally, its capability to spread status adds another layer of utility, making Eternatus a premier choice for balanced team compositions. Toxic Spikes in conjunction with Pressure gives Eternatus a distinct advantage in breaking opposing teams, thanks to its ability to set entry hazards and PP stall Defog from prevalent Defoggers like Ho-Oh and Giratina-O. Toxic serves as a potent tool for gradually wearing down Pokemon such as Calm Mind Primal Kyogre without Rest, Yveltal, and Arceus. Additionally, it ensures gradual damage against defensive Arceus formes lacking Refresh, Primal Groudon, and Ho-Oh. Sludge Bomb finds its primary utility in targeting Arceus-Fairy. Additionally, it offers the potential to poison Pokemon that are immune to Toxic Spikes, notably Ho-Oh and Giratina-O, which would otherwise clear entry hazards against Eternatus. Flamethrower acts as a countermeasure against Steel-types, such as Zacian-C and Necrozma-DM, that would attempt to take advantage of Eternatus, since they are immune to being poisoned. Alternatively, Mystical Fire serves a similar purpose by punishing Steel-types while also limiting Calm Mind Arceus formes. However, it's important to note that Mystical Fire's damage output is weaker than Flamethrower, and as a result, Mystical Fire fails to secure a 2HKO against Zacian-C after Stealth Rock. Flamethrower is also favored as a tool against Necrozma-DM, since it has the potential to inflict a burn, rendering Mystical Fire less effective. Combining Toxic with Toxic Spikes forms another viable strategy that affects all prevalent Defoggers immune to Toxic Spikes, making it easier to maintain entry hazards throughout the match. However, relying solely on these moves without coverage options can leave Eternatus vulnerable against Steel-types like Necrozma-DM, Zacian-C, and Ferrothorn. Leftovers is the preferred item to help Eternatus handle burns from Ho-Oh and mitigate the damage from attacks such as Ice Beam from Primal Kyogre and most attacks from Marshadow. Heavy-Duty Boots serves as a good alternative to avoid entry hazard damage, particularly if the team lacks Defoggers. Eternatus's EV spread enables it to outspeed a fully invested Yveltal while not being 2HKOed by specially offensive Yveltal's Dark Pulse and Choice Band Marshadow's Spectral Thief. An EV spread of 80 HP / 252 SpD / 176 Spe with a Timid nature makes it possible for Eternatus to outspeed fully invested Arceus formes while still not be 2HKOed by specially offensive Yveltal's Dark Pulse at the cost of physical bulk. An alternative spread of 40 HP / 252 Def / 216 Spe, which is faster than Marshadow, can deal with physical threats such as Ho-Oh, Marshadow, and Arceus. However, another dedicated wall is necessary to check specially offensive threats like Primal Kyogre and Arceus-Fairy. Tera Fairy enhances Eternatus's capability against Palkia-O, Life Orb Yveltal, Giratina-O, and Calm Mind Arceus-Dark, while Tera Water improves Eternatus's matchup against Necrozma-DM, Primal Groudon, and Arceus-Ground. Eternatus should freely switch into Yveltal and Ho-Oh lacking Thunder Wave and aim to set up Toxic Spikes to threaten Primal Groudon and defensive Arceus formes. It's best to reserve Terastallization as a last resort, since it compromises Eternatus's valuable Toxic immunity. Ho-Oh synergizes well with Eternatus, especially in the presence of Toxic Spikes, as it can phaze foes with Whirlwind and provides an immunity to Ground. Arceus-Dark is another good partner since it can deal with Necrozma-DM, which is immune to Toxic, and Mega Mewtwo Y. Zygarde-C is another excellent choice as a teammate, offering the ability to safely switch in against Primal Groudon and Marshadow. Additionally, a specially defensive Zygarde-C can utilize Glare against opposing Eternatus, ensuring that it maintains the speed advantage. Giratina is another valuable teammate that is capable of dealing with Primal Groudon. It also has Pressure, which significantly enhances the PP stall strategy when paired with Eternatus. When utilizing physically defensive Eternatus, it's crucial to include another Primal Kyogre check on the team, such as Primal Groudon, Ferrothorn, or Chansey. Ferrothorn can offer valuable entry hazard support by setting up Spikes and Stealth Rock, and it appreciates Eternatus switching in to handle Ho-Oh. Additionally, Chansey can effectively handle most special attackers and use Heal Bell to cure eventual paralysis on Eternatus, further increasing Eternatus's longevity throughout the match.

Meteor Beam Eternatus is one of the premier specially offensive Pokemon in the tier for hyper offense, leveraging its unique mixture of an excellent Speed tier, solid defensive traits, and great coverage. Eternatus is one of the fastest special threats in the tier while maintaining respectable bulk, making revenge killing it challenging. Additionally, as one of the few viable Poison-types in the tier, Eternatus provides a Toxic Spikes absorber for hyper offense teams. Meteor Beam provides Rock coverage to OHKO Ho-Oh and Yveltal, which are otherwise bothersome to remove. Given this, Meteor Beam should be reserved for these targets when possible. However, if these threats are sufficiently weakened, Meteor Beam may also be used to KO weakened Pokemon such as Primal Groudon, allowing Eternatus to leverage the Special Attack boost immediately with its other moves. Sludge Bomb hits Arceus-Fairy and Mega Diancie, as well as Tera Fairy Pokemon, such as Zygarde, aiming to blank Eternatus. Additionally, against bulkier opponents, Sludge Bomb's poison chance is incredibly useful in helping Eternatus muscle through. Examples of such targets include many soft checks such as Calm Mind Arceus formes, Ho-Oh after Meteor Beam has been used, and Primal Kyogre, especially its defensive variants. Fire Blast, at +1, OHKOes Zacian-C as well as Calyrex-I after Stealth Rock. Flamethrower is a niche alternative that can be paired with Tera Fire. However, the damage loss is noticeable as it fails to achieve either of the aforementioned benchmarks without Tera. Unboosted Flamethrower also fails to OHKO Ferrothorn. Tera Dragon boosts +1 Dynamax Cannon to absurd levels, OHKOing defensive staples such as defensive Primal Groudon after three layers of Spikes, Tera Water Zygarde after Stealth Rock, and offensive Yveltal. Additionally, Tera Dragon allows +1 Dynamax Cannon to 2HKO Ho-Oh and muscle through Arceus-Dark if it switches in on Meteor Beam. After a Sludge Bomb poisoning, unboosted Tera Dragon Eternatus can 2HKO Calm Mind Arceus formes. Tera Dragon additionally removes Eternatus's Ground and Psychic weaknesses, helping against the likes of Groudon, Zygarde, Ultra Necrozma, and Necrozma-DM. Please note that Ultra Necrozma's Light That Burns the Sky still OHKOes Eternatus after Terastallization, and Deoxys-A's Psycho Boost has a favorable roll to OHKO as well. As previously mentioned, Tera Fire is an alternative option to boost Eternatus's Fire coverage while also flipping the defensive type matchup against Zacian-C, Calyrex-I, and the rarer Arceus-Fairy. Tera Fire enables Fire Blast to OHKO Zacian-C without a boost and Flamethrower to OHKO Dragon Dance Necrozma-DM after a boost and minimal chip damage. Tera Fire also allows Eternatus to survive Zacian-C's +3 Behemoth Blade, Calyrex-I's +1 Glacial Lance, and Choice Band Chien-Pao's Ice Spinner. Meteor Beam Eternatus fits best on entry hazard stacking hyper offense teams capable of providing it the necessary hazard support to break through some of the walls in the tier. In turn, Eternatus offensively pressures every relevant Defogger with an OHKO unless they defensively Terastallize. However, a well-timed defensive Terastallization from the likes of Ho-Oh and Giratina-O can allow them to use Thunder Wave, crippling Eternatus's Speed and enabling them to use Defog after. Eternatus is also an effective mid-to-late-game cleaner due to its natural bulk, making it challenging to revenge kill. Eternatus also fits well on Sticky Web teams that allow it to outpace otherwise faster threats, but the lack of entry hazard damage reduces its effectiveness versus bulkier teams. Furthermore, Eternatus faces stiff competition from fellow Meteor Beam user Lunala, which can block Extreme Speed and Rapid Spin and has access to Psyshock. Eternatus pairs well with physical attackers such as Extreme Killer Arceus and Dragon Dance Ultra Necrozma that appreciate its ability to break physical walls and revenge kill Marshadow. In turn, their access to priority or Speed boosting moves, respectively, helps pressure the special walls and naturally faster Pokemon Eternatus struggles with. In addition to requiring Meteor Beam to OHKO Pokemon such as Ho-Oh and Yveltal, Eternatus is deceptively weak without the Special Attack boost. As such, it is often important to position Eternatus to commit to wallbreak or sweep lest the one-time use of Power Herb go to waste. In the event Eternatus is forced out after using Meteor Beam without making meaningful progress, Eternatus becomes far less threatening and is largely relegated to late-game cleaning or revenge killing. Despite being a powerful threat capable of brute forcing through many defensive staples, Meteor Beam Eternatus struggles considerably against stall due to its lack of longevity. Due to this, Eternatus should be paired with dedicated stallbreakers, wallbreakers, and teammates that otherwise fare better against such teams, such as offensive Yveltal with Knock Off, Chi-Yu, Dragon Dance Necrozma-DM, Meteor Beam Lunala, and Kyurem-B. Additionally, Eternatus uniquely absorbs Toxic and Toxic Spikes from opposing defensive Eternatus. Some common defensive checks to Eternatus include Calm Mind Arceus forms and Fezandipiti. Eternatus is additionally hard-walled by Chansey. Given this, Eternatus appreciates teammates that can punish them, such as Zacian-C and Necrozma-DM, and allies that can help overwhelm these shared checks such as wallbreaker Primal Kyogre, offensive Yveltal, and Meteor Beam Lunala.

Shuca Berry Eternatus fully maximizes its poison-spreading potential, being able to use Toxic and set Toxic Spikes on Primal Groudon and Arceus-Ground with relative safety after luring them in. Shuca Berry also comes with the added benefit of letting Eternatus check Choice Band Marshadow much more effectively, as once it is used, Poltergeist will be unable to hit it. This set still performs defensive Eternatus’ s standard roles effectively as a check to foes such as Calm Mind Arceus sets lacking Refresh and Yveltal, but it can struggle long term against Arceus-Fairy and Life Orb Yveltal due to being prone to being worn down without Leftovers or Heavy-Duty Boots. Furthermore, as it is unable to use both Dynamax Cannon and Flamethrower, it can be used as setup fodder for Zacian-C, Necrozma-DM, or opposing Eterrnatus depending on its choice. With Shuca Berry, Eternatus can safely stay in on Ground-types like Primal Groudon and use Toxic against it, and it also is key to pressuring Ho-Oh and defensive Arceus sets, letting Eternatus constantly set Toxic Spikes against them. Toxic also allows Eternatus to wear down Calm Mind Primal Kyogre and Zygarde, forcing them to use Rest more frequently. Toxic Spikes lets Eternatus put pressure on defensive Arceus formes, Primal Groudon, and Primal Kyogre, wearing them down and enabling its teammates to break through them more easily. Dynamax Cannon lets Eternatus directly hit Ground-types like Primal Groudon, Arceus-Ground, and Ho-Oh, and it most importantly dissuades opposing Eternatus from switching in and absorbing its Toxic Spikes. Flamethrower can be used if Necrozma-DM and Zacian-C are an issue to the team but makes the set less effective overall due to the lack of a STAB option, as it is harder to pressure Ho-Oh and Zygarde. The given EV spread allows Eternatus to avoid the 2HKO from Zygarde’s Thousand Arrows with Shuca Berry, avoid the 2HKO from Life Orb Yveltal’s Dark Pulse, and outspeed specially offensive Yveltal. Tera Fairy lets Eternatus take Dragon-type attacks from opposing Eternatus and Palkia-O while also being an all-around great defensive type that turns its former Ground and Psychic weaknesses into neutralities and keeps its Fighting resistance against Marshadow. Shuca Berry Eternatus works best early- to mid-game, as if it can lure Primal Groudon or Arceus-Ground with Toxic, it can start putting a lot of pressure on the opposing team. Using its item early is also the best case scenario when fighting a Marshadow so it can pivot into it without worry. Hard switching in Eternatus is often discouraged, as it can lose its Shuca Berry and be KOed after without being able to use Toxic or Dynamax Cannon. Toxic Spikes can easily be set up, as Eternatus can pressure all Defoggers by way of Toxic and Dynamax Cannon. This set works best on balance and bulky offense structures that appreciate Eternatus spreading poison on Ho-Oh and Primal Groudon, greatly cutting into their longevity. Shuca Berry Eternatus works best with teammates that greatly appreciate Ground-types being poisoned or KOed, such as Calm Mind Arceus-Water, Calm Mind Arceus-Fairy, and offensive Primal Groudon. Eternatus is easily worn down by entry hazards, so teammates that can remove them like Ho-Oh, Yveltal, and Giratina-O are great partners. Eternatus must be paired with good Zacian-C and Necrozma-DM checks if running Dynamax Cannon, so defensive Primal Groudon and Zygarde-C are good teammates. If running Flamethrower, then teams must have a way to pressure or take advantage of opposing Eternatus such as Choice Band Marshadow or offensive Yveltal.

Wallbreaker Eternatus is an immensely threatening wallbreaker, and not only maintains resiliency to passive damage that would wear down other offensive sets against bulkier teams but also lacks the passivity of defensive sets. This amalgamation of offensive and defensive traits provides valuable role compression for many bulky offense and balance teams, which appreciate Eternatus's consistency against both offensive and defensive playstyles. Recover provides Eternatus immense flexibility relative to other offensive sets. Eternatus often finds turns to use Recover on the switches it forces or against more passive Pokemon that struggle to meaningfully damage it such as Ho-Oh, Ferrothorn, or Yveltal attempting to KO with Sucker Punch. Meteor Beam provides Eternatus with the ability to easily remove Flying-types such as Ho-Oh and Yveltal. Meteor Beam also dissuades Pokemon that would otherwise switch into Eternatus such as Primal Kyogre or Primal Groudon, as they are unable to handle Eternatus's boosted attacks afterwards. Fire Blast is used over Flamethrower for increased damage, notably OHKOing Zacian-C at +1 and being able to 2HKO defensive Necrozma-DM. Fire-type coverage is run to easily handle Steel-types and Pokemon that utilize Tera Steel that would wall or set up on Eternatus such as Necrozma-DM, Zacian-C, and Giratina-O. Tera Fairy is the primary Tera type used. It enables Eternatus to comfortably switch into specially offensive Yveltal and prevents it from being revenge killed by Ditto. Eternatus can also Terastallize in a pinch to remove its Ground weakness against Pokemon aiming to revenge kill it such as Primal Groudon and Arceus-Ground. Eternatus's newfound Dragon immunity also helps against Giratina-O, Palkia-O, and opposing Eternatus. Eternatus tends to enter the battle mid-game against defensive Pokemon such as Ho-Oh, utility Arceus-Fairy, and Ferrothorn. Eternatus can use these as an opportunity to boost, wallbreak, or both. It does not need to micromanage its health, as it often finds opportunities to use Recover against defensive Pokemon, so it is capable of sponging a hit beyond what is required in order to set up. Eternatus also has a great matchup into stall teams, as Chansey is often left with too little PP to stave off other special attackers such as Primal Kyogre after dealing with Eternatus thanks to Pressure. Alomomola is a fantastic teammate for Eternatus thanks to its ability to provide a slow pivot into Pokemon that Eternatus can beat but is otherwise hesitant to switch directly into, such as Zygarde and defensive Eternatus. Zygarde is also an excellent partner for Eternatus, as it is the tier's best blanket physical wall to handle Pokemon such as Primal Groudon and Tera Blast Ground Zacian-C. Zygarde's paralysis support also enables Eternatus to easily revenge kill Pokemon such as Zacian-C and Ultra Necrozma with minimal risk. Choice Band Marshadow can handle the few specially defensive Pokemon that Eternatus struggles with such as Calm Mind Arceus formes and defensive Primal Kyogre. Zacian-C is another option, which handles Calm Mind Arceus formes that can otherwise use Eternatus for setup fodder.

Choice Specs Eternatus serves as a more specialized variant that aims to fully capitalize on its offensive potential as a wallbreaker with ample opportunity to outpace and cleave through prominent defensive cores over the course of a game. It successfully combines the unresisted coverage of the Power Herb variants and packs more immediate power while lacking the recoil of Life Orb, giving it a distinct niche. The ability to include Sludge Bomb is one of this set's most appealing traits, giving Eternatus a strong secondary STAB move to heavily threaten Tera Fairy Zygarde, IronPress Garganacl, and Arceus-Fairy. Additionally, its poison chance can prove vital in overpowering the likes of setup sweepers such as Calm Mind Arceus-Dark and defensive pivots such as Ho-Oh, which can otherwise outheal the damage dished out. Fire Blast provides important coverage against Steel-types such as Zacian-C, Necrozma-DM, and Ferrothorn. It is used over Flamethrower due to its higher Base Power that allows Eternatus to OHKO Zacian-C. The secondary option of Draco Meteor serves as another major draw behind this set. The immediate power offered by Draco Meteor allows Eternatus to KO important targets that Dynamax Cannon would otherwise come up short against, such as weakened Ho-Oh, Calm Mind Arceus formes and Alomomola, freeing it from the need to Terastallize against them. Being able to outright remove these Pokemon at designated HP thresholds, rather than letting them hang on by a thread, can mean the difference between their continued persistence and permanently removing them to the benefit of Eternatus's teammates later in the match. Alternatively, Toxic Spikes allows Eternatus to take advantage of its ability to force switches to lay down entry hazards to support its teammates, which can be especially useful for crippling setup sweepers such as Dragon Dance Zygarde, Swords Dance Arceus, and Calm Mind Arceus formes even when Eternatus is not on the field, but is more situational as the presence of common Poison-types like other Eternatus, Fezandipiti and Tera Poison Calm Mind Arceus formes limit its usability. Tera Dragon strengthens Eternatus's already strong Dynamax Cannon and Draco Meteor, notably allowing Dynamax Cannon to consistently 2HKO Arceus-Dark through a Calm Mind boost, defensive Primal Kyogre, and Ho-Oh, while allowing Draco Meteor to OHKO maximum HP Arceus formes after Stealth Rock, defensive Primal Groudon, and Tera Water Zygarde before Power Construct. It also crucially removes Eternatus's Ground-type weakness, allowing it to survive hits from Primal Groudon in a pinch. However, Eternatus will lose its ability to absorb Toxic Spikes and Toxic. Choice Specs Eternatus fits best on bulky offense and balance teams that appreciate its ability to act as a strong wallbreaker with some additional defensive utility via absorbing poison from defensive pivots such as Alomomola. It also serves as an offensive check to other offensive threats such as Marshadow and Life Orb Yveltal. While Eternatus is an effective wallbreaker against opposing bulky offense and balance teams commonly featuring the likes of Primal Groudon, Arceus formes, and Terastallized Zygarde, it tends to struggle the most against extreme playstyles such as hyper offense and stall. Hyper offense teams can overwhelm Eternatus with setup sweepers such as Dragon Dance Ultra Necrozma, Dragon Dance Necrozma DM, and Zacian-C that take advantage of it being Choice-locked, while stall teams tend to pack Pokemon that hard wall it such as Chansey. Eternatus's ability to break open defensive cores is best complemented by setup sweepers that appreciate the gaping holes it tends to leave behind; the likes of Zacian-C and Dragon Dance Arceus-Ground fit well on more offensive teams, while Coil Zygarde benefits similarly on more balanced structures. In return, these Pokemon can greatly assist with more offensive teams that might give Eternatus trouble wallbreaking, such as against hyper offense structures loaded with miscellaneous offensive threats such as Dragon Dance Mega Salamence and Rock Polish Primal Groudon that can outspeed and OHKO Eternatus after setting up. Eternatus greatly detests the presence of entry hazards such as Stealth Rock and Spikes, which are set by common Pokemon such as Primal Groudon and Ferrothorn and heavily cut into its longevity. Teammates that can help manage these factors consist of Defog users such as Ho-Oh, Giratina-O, and Mega Salamence, which can reliably remove these conditions throughout the match. In return, Eternatus helps break past defensive Pokemon that these partners can otherwise struggle with long term, such as Zygarde, defensive Primal Groudon, Garganacl, and Alomomola. Additional options against Sticky Web are mandatory in particular due to how they entirely ruin Eternatus's ability to wallbreak by compromising its Speed tier to where it is unable to handle the likes of Chi-Yu, Yveltal, and Lunala on the archetype. As a result, anti-lead Pokemon such as Dragon Dance Zygarde and defensive Primal Kyogre are excellent for their ability to punish the most common Sticky Web setter in Smeargle, while additional support from revenge killers such as Choice Scarf Yveltal and Extreme Killer Arceus that aren't affected by Sticky Web can assist Eternatus with picking off several of the aforementioned offensive Pokemon mid-game. Without proper prediction, Eternatus has trouble breaking through teams that carry multiple Pokemon with appropriate resistances to its moves such as Zacian-C, Fezandipiti, and Arceus-Ground, which can take advantage of it being Choice-locked when paired with pivots like Ho-Oh that can safely scout it. As such, checks such as defensive Primal Groudon, defensive Primal Kyogre, and Ho-Oh are necessary to provide a safety net against these Pokemon and minimize the degree to which Eternatus is punished. Zacian-C in particular is a notable threat, as it is fully immune to both of Eternatus's STAB types and can both outspeed and set up Swords Dance against it. As a result, Eternatus also occasionally appreciates being paired with revenge killers such as Ditto and Choice Scarf Yveltal. Lastly, as Eternatus prefers not to directly switch into targets such as offensive Ho-Oh, Arceus-Dark, and Giratina-O, which can often cripple it with status, pivots such as defensive Yveltal, Landorus-T, and Alomomola are strong teammates that can help Eternatus get onto the field safely against these Pokemon. Yveltal can cripple several of Eternatus's switch-ins such as Chansey and Ho-Oh with Knock Off and Taunt, while Alomomola can use Wish to compensate for Eternatus's lack of recovery and susceptibility to being worn down throughout a match. Secondary pivots to Calm Mind Arceus formes are also notable, as after a Calm Mind boost, Arceus-Dark and Arceus-Fairy will be able to outheal the damage Eternatus can dish out and commonly run Tera Poison to gain an immunity to poison; Choice Band Marshadow forms an effective offensive pairing with Eternatus and can force these Pokemon out with Spectral Thief's ability to steal boosts, while Ho-Oh can safely switch into and apply pressure to these Pokemon with status from Sacred Fire and Thunder Wave.
