Regirock Movesets & Competitive Sets

Moves Regirock's main use is to set up Sunny Day. Explosion inflicts heavy damage on anything without a resistance to it while KOing Regirock in the process. Explosion's purpose is twofold: not only does Regirock KOing itself prevent Stealth Rock from being removed by slower users of Defog and Rapid Spin, but this also allows partners that take advantage of sun to enter battle safely. Regirock's Attack-invested STAB Stone Edge is effective for dealing with the Fire-, Bug-, Ice-, and Flying-types such as Simisear, Scyther, Jynx, and Oricorio-E that pose a threat to the Grass-types found on Sunny Day teams and can be utilized in matchups where it is better to preserve Regirock than to use Explosion. Set Details Sturdy guarantees that Regirock will be able to set up either Stealth Rock or Sunny Day. Heat Rock increases the number of turns that Sunny Day is active, thereby increasing the time sun sweepers are functioning at peak performance. Usage Tips Given that Sturdy is key to successfully setting up with Stealth Rock and Sunny Day, Regirock should be brought out early-game before the opponent can deactivate the ability via entry hazards. Switch Regirock out of Pokemon like Sableye and Jellicent that can either burn it with Will-O-Wisp or prevent it from supporting its teammates via Taunt. The momentum Regirock's Explosion provides is conducive to bringing in frail Chlorophyll sweepers like Victreebel and Shiftry for free, and it is generally a more effective method than hard switching into resisted attacks for starting a sweep. Regirock should use Explosion on the turn immediately following Sunny Day in order to maximize the number of turns its teammates can operate with sun in play, unless Regirock should be kept alive to combat Normal- or Flying-types like Kangaskhan and Oricorio-E. Kangaskhan in particular is important for sun teams to beat, as it wastes turns of Sunny Day via Fake Out. It can be advantageous to prioritize Sunny Day's use over Stealth Rock or vice versa; it is best to determine first whether the opposing team is weaker to sun sweepers or Stealth Rock and act accordingly. Sunny Day also has some defensive utility in matchups against offensive Water-types, as it reduces the damage of Water-type moves for Regirock and its Fire-type teammates. Team Options Sunny Day Regirock is intended to complement Chlorophyll-reliant sweepers and Fire-types that can use Sunny Day to maximum effect; therefore, this variant of Regirock only fits on dedicated sun-based teams. Fire-types like Simisear are most threatening when played in sun, as Sunny Day boosts the power of their STAB moves significantly. Additionally, Sunny Day effectively negates Simisear's weakness to Water-type attacks and enables the use of a single-turn Solar Beam against bulky Rock-types that would otherwise counter them, such as Carbink. In return, Simisear checks Grass- and Steel-types for Regirock, such as Tangela and Metang. Powerful Grass-type sweepers like Shiftry, Exeggutor, Victreebel, Sawsbuck, and Leafeon all capitalize on Regirock's Sunny Day by doubling their Speed via Chlorophyll, and they become much more difficult to revenge kill as a result. Additionally, Regirock further bolsters their effectiveness by laying Stealth Rock, which limits the number of times that opposing Fire-, Bug-, and Flying-types can pivot into these sweepers' Grass-type attacks. Given that Regirock uses Explosion after setting Sunny Day early-game, mid- and late-game setters of Sunny Day are required to provide sun-based teams with continued support. Prankster Volbeat and Liepard fulfill this role by setting up Sunny Day with priority. Volbeat in particular shares excellent synergy with Regirock due to its ability to pivot into Grass-, Ground-, and Fighting-type moves from Pokemon such as Bellossom, Alolan Dugtrio, and Hitmonchan. Lastly, Sunny Day setters with access to self-KOing moves like Memento and Healing Wish are useful partners to Regirock. For example, Alolan Dugtrio equipped with Sunny Day and Memento eases the setup of sun-based sweepers like Victreebel and Turtonator. Furthermore, it can use its STAB moves to threaten Pokemon that are problematic to sun-based teams such as Snow Warning Aurorus and Abomasnow.

Moves Stone Edge is a more powerful alternative to Rock Slide, but its accuracy and PP make it somewhat unreliable and it can be PP stalled by Pokemon such as Articuno. Drain Punch lets Regirock threaten Ice-types like Alolan Sandslash and Aurorus and Normal-types like Kangaskhan, and it gains notable recovery from the aforementioned targets as well as Primeape with lowered Defense. Earthquake is an alternative that deals more damage to targets like Aggron and Skuntank and can be used to threaten Qwilfish upon switch-in, but it notably worsens Regirock's hail matchup. Toxic is used to cripple Regirock's regular switch-ins and places a timer on setup sweepers that might attempt to take advantage of Regirock's passive nature. Toxic is also Regirock's most reliable means of dealing significant damage to bulky Ground-types like Mudsdale and other physically defensive Pokemon with recovery like Jellicent and Tangela. Protect can be used over Toxic to scout for Choice-locked Pokemon like Primeape and Stoutland and stall for extra Leftovers recovery. Set Details Clear Body is Regirock's ability of choice, as it blocks Parting Shot from Silvally formes and Alolan Persian. A Chople Berry can be used to reduce the damage of super effective Fighting-type moves, such as Primeape’s Close Combat. Maximum HP investment and 180 EVs in Defense along with an Impish nature prevent Regirock from being 2HKOed by Adamant Aggron's Choice Band-boosted Head Smash and Primeape’s unboosted Close Combat from full. Additionally, Regirock has a high chance to survive Zangoose's Close Combat, even after tanking its high-powered Facade. Its remaining EVs are allocated toward its Special Defense, which helps Regirock check Pokemon such as Oricorio-E. Usage Tips Use Regirock's massive Defense stat and Rock typing to pivot into resisted attacks from Pokemon like Kangaskhan and physically offensive Skuntank in order to set up Stealth Rock. If Stealth Rock is already on the field, Regirock can use this opportunity to attack or to weaken its switch-ins with Toxic. Even with Special Defense investment, Regirock can still be overrun by powerful wallbreakers such as Choice Specs Drampa so it is best to either use Protect to ease prediction against these Pokemon or switch out altogether. It is generally good practice with Regirock to switch out against incoming status moves, as effects like Toxic will severely reduce its longevity and consequently disallow Regirock to switch into the Pokemon that it was meant to check. Protect should be used when Regirock either has an opportunity to stall out foes afflicted with Toxic or is at risk of being KOed. However, be careful of using Protect too often, given its frequent use can supply Regirock's foes with free turns to set up and sweep or to lay entry hazards that would be detrimental to Regirock's longevity. Team Options In general, Regirock fits on balanced and bulky offensive teams and is effective in aiding sweepers and wallbreakers that function optimally with Stealth Rock support. For example, offensive partners that are able to pivot into and threaten Grass-types for Regirock by virtue of their typing or ability such as Drampa and Oricorio-G perform at their peak when Stealth Rock is up. Additionally, Drampa is able to use Regirock's weakness to Grass-type moves to gain momentum and fire off powerful attacks. Other Pokemon that resist Grass-type moves for Regirock, like Lurantis and Skuntank, remove entry hazards for it via Defog, which is crucial in preserving Regirock's longevity given its lack of reliable recovery. Skuntank in particular is effective in this capacity, as it absorbs Toxic Spikes for Regirock upon switching in. Checks to Ground-types share excellent synergy with Regirock; for example, Eelektross absorbs Ground-type moves via Levitate and checks Mudsdale and Simisear on Regirock's behalf. Given Regirock counters physically offensive Skuntank, Psychic-, Ghost-, and Grass-types that appreciate Skuntank's absence are ideal teammates.

Moves Diamond Storm is Regirock's preferred STAB move, dealing decent damage against most foes that don't resist it while having a nifty 50% chance to boost Regirock's Defense. U-turn is a great move for grabbing momentum, allowing Regirock to exploit its low Speed to give teammates a free switch. Sacred Fire allows Regirock to cripple physical attackers like Mega Mewtwo X on the switch, as well as allowing it to threaten Shedinja somewhat. However, Nuzzle is also an option to cripple offensive Pokemon in general. Knock Off has obvious, general utility; notably, it allows Regirock to neuter the offensive power of threats carrying Life Orb or other boosting items, as well as removing Eviolite from Chansey and stopping Toxic Orbs on the switch. Knock Off also discourages cleric support alongside Poison Heal users even once their Toxic Orbs are set—while the poisoning initially remains, removing the Toxic Orb means that Poison Heal will stop working if your opponent elects to use Heal Bell or Aromatherapy. Finally, Infestation is another option to surprise Shedinja if you opt against running Sacred Fire. Set Details The EV spread given allows Regirock to always avoid the 2HKO from Adamant Sky Plate Mega Rayquaza's Thousand Arrows or Boomburst after Stealth Rock. It also affords Regirock the ability to check Mega Gengar in a pinch, as it is not OHKOed by +2 Spooky Plate Judgment or Secret Sword. However, if Mega Gengar carries Spore, Regirock will struggle to check it. The rest of the EVs are poured into Attack in order to give Regirock as much offensive presence as possible. Regenerator enables Regirock to recover passively without wasting turns to do so, while Assault Vest buffs up its relatively low Special Defense and synergizes well with Regenerator. Usage Tips Regirock thrives on forced switches; U-turn, Sacred Fire, Nuzzle, and Knock Off are all tools that you can capitalize upon and grab momentum or cripple the foe. Because of Regirock's demonstrable efficacy in crippling foes on the switch, it's a good idea to identify the members of your opponent's team that Regirock can force out and exploit to the fullest. Early-game, it's also a good idea to make copious use of U-turn to identify what the opponent's strongest answer to Regirock is. Even later on in the game, U-turn is a great, safe option to snag momentum against foes that Regirock walls. Because Regirock is incredibly susceptible to status, you should scout around to identify which members of the opposing team can burn it or put it to sleep and act accordingly—getting hit with either of these statuses can leave Regirock functionally useless. Finally, if you opt to use Infestation, this should be hidden against opponents running Sturdy Shedinja until you can bait the Shedinja to come in on Regirock's attacks; otherwise, a smart opponent will simply pivot out and make it quite difficult to land the Infestation. Team Options Poison Heal Giratina makes for a fantastic teammate to Regirock. Not only can it counter an Imposter of Regirock with ease, but it also boasts excellent defensive synergy with Regirock and can soak up status for it. In addition, Regirock's slow U-turn gives Giratina an easy way to activate its Toxic Orb or nab an extra turn of Poison Heal recovery. If Regirock doesn't run Infestation, a Mold Breaker Pokemon with Pursuit such as Mega Gengar, Giratina, or Mega Gyarados can also be very useful to take care of Shedinja, once again capitalizing on Regirock's U-turn to ease prediction. Entry hazard control is essential to Regirock's success, making a solid Defogger such as Giratina or Registeel an excellent teammate. Ideally, Regirock would also appreciate entry hazards down on the opponent's field to capitalize on with its U-turn; however, as keeping hazards off of its own side of the field is the primary concern and Defog is the most reliable way to do this, stacking hazards is often forced to take a back seat. Another way to limit hazards is with a Magic Bounce user (again, Giratina and Registeel are prime contenders), which can also be useful to redirect the status that Regirock attracts like a magnet; however, Mold Breaker can easily bypass it. While Regirock is certainly bulky, it struggles to switch in against Pixilate and, to a lesser extent, Refrigerate attackers such as Mega Diancie and Kyurem-B. Therefore, a secondary check to these two must be included as a teammate. However, Regirock's alleviation of the pressure from Aerilate allows greater flexibility in checking the other two –ate Pokemon. Finally, a cleric such as Registeel or Mega Audino is a good idea for a teammate, preventing Regirock from becoming dead weight if put to sleep or burned unexpectedly, although it synergizes poorly with Poison Heal on other teammates.

With Stealth Rock almost an absolute necessity on every team, Regirock is a reliable and consistent Stealth Rock user. It defeats Cryogonal one on one, meaning that spinblocking against Cryogonal isn't compulsory as you could switch Regirock in as Cryogonal uses Rapid Spin and just set it back up again. Rock Slide is chosen as the STAB move over Stone Edge thanks to its higher PP and better accuracy to deal consistent damage; it also OHKOes both Moltres and Cryogonal. Thunder Wave and Toxic are both secondary support options to cater to teams. Thunder Wave slows down sweepers and other offensive threats such as Durant and Stoutland, whereas Toxic is an option for use on defensive teams looking to stall out foes and to cripple many of Regirock's common switch-ins, such as Lanturn and Gallade. Protect can be used in the fourth slot to scout for moves such as Medicham's High Jump Kick while letting Regirock heal with Leftovers and helps Regirock to check Fire-types more reliably in the long run. Protect helps to stall out foes with poison damage from Toxic. Earthquake is yet another reliable attacking move that dents Kabutops and Steel-type switch-ins such as Steelix and Aggron. A specially defensive EV spread allows Regirock to handle Fire-type behemoths such as Moltres, and Regirock still has plenty of physical bulk even without investment. Here are some damage calculations to demonstrate Regirock's huge special bulk and its still-high physical bulk: 252 SpA Life Orb Moltres Hidden Power Grass 38.46 - 45.6% 252 SpA Life Orb Moltres Fire Blast 24.72 - 29.12% 252 Atk Choice Band Hustle Durant Iron Head 77.47 - 91.2% Moltres can manage a maximum of 74.7% damage in total with one Fire Blast and Hidden Power Grass. Thus, bar a critical hit or burn, Regirock needs about 62% HP after entry hazards to check Moltres if Regirock has Protect. Specially defensive Regirock is no slouch physically either, as shown by Choice Band Durant's failure to OHKO it from full health. Wish support from teammates such as Clefable and Alomomola are good options to keep Regirock healthy as it often needs to be at high HP to be able to check the aforementioned threats. Rapid Spin support from Cryogonal, ironically, is also helpful as Regirock has no reliable recovery and appreciates the removal of hazards. However, this compounds your team's Fighting-type weakness, so Ghost-types such as Rotom and Spiritomb, bulky Poison-types such as Qwilfish and Amoonguss, and Psychic-types such as Mesprit and Uxie will come in handy. Other Grass-types, such as Tangrowth and Roselia, are also good teammates as they resist Water- and Grass-type attacks; the latter can also provide further entry hazard support. Aside from defensive teammates, offensive Pokemon such as Moltres and Lilligant are also good teammates as they can capitalize on the status spread by Regirock and fall back on its defenses if they fail to pull off a sweep. Stone Edge is an option over Rock Slide for added power, but it can be stalled out easily by SubRoost Moltres and has poorer accuracy. Rock Slide is often enough as it is usually used against foes weak to it.

Regirock's Rock typing is a huge boon for sun teams. It pairs well with many sun sweepers as it can take Fire-type attacks targeting Grass-type sweepers while also resisting common priority moves or being bulky enough to sponge them. Many priority users, such as Extreme Speed Entei, Belly Drum Linoone, and Swords Dance Absol, threaten sun teams due to their sweepers' frailty. Regirock is able to check the aforementioned Pokemon. It also benefits from sun as its Water weakness is negated, and its natural Fire resistance lets it shrug off even sun-boosted attacks. Regirock can set up not only Sunny Day, but also Stealth Rock, and is thus a good utility teammate for sun teams. It can often set up Sunny Day more than once when needed, as it has the defenses to keep itself healthy enough for another setup. Rock Slide is the main STAB move used, often to check opposing Fire-types hoping to take advantage of sun-boosted Fire-type attacks. However, when relying on Regirock to check Fire-types, be wary of the occasional Solar Beam from Pokemon such as Typhlosion. Rock Slide is also useful for dealing with Cryogonal, a common Rapid Spin user. Fire Punch receives pseudo-STAB from sun, where it is just as powerful and even more reliable than Rock Slide. Escavalier and Durant are both notable foes that Fire Punch works extremely well against, and the former is often even slower than Regirock as it usually does not invest in Speed. Explosion, however, is a usable last resort to deal damage while bringing in another teammate safely, possibly paving a way for a sweep. A specially defensive EV spread enables Regirock to tank special hits more comfortably as it already has sufficient physical bulk. It also allows Regirock to sponge common special Water-type attacks such as Scald, and physical ones aren't going to break through Regirock while weakened by sun. As with all dedicated sun inducers, Heat Rock is used to prolong the sun. Thunder Wave is another option to support the team as it slows down foes, which can be helpful in the event that the sun is out. Toxic deters opponents from stalling out sun with Protect, though Thunder Wave is usually the better option for an offensive sun team. Stone Edge can be considered for added power over Rock Slide. For other great Sunny Day users as teammates, Uxie is a good partner and complements Regirock, as it resists Fighting and is immune to Ground. Furthermore, with Regirock taking care of Stealth Rock, Uxie will be able to free up a moveslot for another support move such as Heal Bell. Sun sweepers are definitely compulsory teammates. Victreebel, Exeggutor, Moltres, and Sawsbuck are common sun sweepers. However, defensive sun-reliant teammates such as Harvest Exeggutor are also usable, though less common.

The idea of this set is to come in on a Pokemon who doesn't threaten Regirock, such as Heatran, Zapdos, or Weavile, and start setting up. After a Curse or two, Regirock will be able to take even super effective physical attacks with over half of its HP remaining. Should your opponent's special attackers be gone, Regirock will become hard to stop. When Regirock is running low on health, it can just Rest off the damage, wake up instantly thanks to Chesto Berry, and attempt a sweep. When using Regirock, it's inevitable that it will be compared to Tyranitar. Regirock has its advantages, however; it has superior Defense, lacks the 4x weakness to Fighting-type attacks, and doesn't have a weakness to Bug-type attacks. This enables it to come out on top against Gyarados, Dragonite, Lucario, and Scizor, all of whom Tyranitar loses to. Stone Edge is an option over Rock Slide, as the extra power is sometimes helpful at the cost of less PP. In the last slot, Sleep Talk is an option, as it allows Regirock to use Rest more than once without becoming set up bait, and lets it use Leftovers instead of Chesto Berry. Running Stone Edge becomes more viable due to Sleep Talk consuming PP for Stone Edge; however, running Sleep Talk over Earthquake gives Regirock a much harder time against Steel-types. The EVs can also be tweaked by investing in either more Defense or Attack should you want more physical bulk or attacking power, respectively.

This set focuses on Regirock's ability to check numerous threats in the UU metagame, while also being able to pose a threat offensively. Regirock's excellent Defense aids it in countering and checking many physical sweepers. Additionally, Regirock can use its impressive bulk to aid its team through its support moves. Stone Edge and Earthquake create the famous EdgeQuake combination, which provides great type coverage, backed by Regirock's respectable Attack stat. Stealth Rock is secured a spot in the third slot because it allows Regirock to provide some team support while also taking advantage of Regirock's ability to set it up reliably. Explosion differentiates Regirock from Pokemon such as Rhyperior and Aggron. A well-timed Explosion can turn the tide of a match by eliminating a problem Pokemon your team may have trouble facing. Stone Edge is best used with Earthquake, as 8 PP is too little to rely on for a wall such as Regirock. Earthquake also gives Regirock a way to hit Steelix and Registeel, as well as Fighting-types. However, paralysis support is always useful, and if Thunder Wave is chosen over Earthquake, then Rock Slide becomes the superior option over Stone Edge. With Rock Slide, Regirock will not have PP issues, and also gains access to a nice flinch chance. An alternative to Thunder Wave is Toxic, which can severely cripple Pokemon such as Milotic and Donphan as they switch in. If you already have a reliable Stealth Rock user, such as Mesprit or Uxie, Toxic can go in the third slot to complement either Earthquake or Thunder Wave. Rest can be used over Explosion to ensure Regirock sticks around a bit longer; however, it would be wise to pair Regirock with a cleric such as Chansey or Clefable so it's not a sitting duck. With the given EV spread, Regirock can comfortably defeat powerful threats such as Mismagius and Houndoom, never being OHKOed by a +2 Hidden Power Fighting or Dark Pulse, respectively. If a more hard-hitting Regirock is desired, an alternative EV spread of 252 HP / 252 Atk / 4 SpD Adamant may be used, but Regirock now has a decent chance of being OHKOed by Timid Life Orb Alakazam's Focus Blast and Nasty Plot Houndoom's +2 Dark Pulse. Finally, another alternative EV spread of 252 HP / 4 Atk / 252 SpD with a Careful nature can be used to fully maximize Regirock's special tanking abilities, made better if used in a sandstorm. Regirock can also check Pokemon such as Blaziken and Moltres. Blaziken only causes trouble if Regirock is weakened, or if Blaziken runs rare moves such as Focus Blast or Swords Dance. With its amazing defenses, Regirock can switch into Moltres, OHKOing it with its STAB Rock-type move of choice. Regirock really enjoys having a Grass-type to sponge Water-, Grass-, and Ground-type attacks thrown at it. Pokemon such as Venusaur provide nice support for Regirock by bringing down bulky Water-types. Altaria is another Pokemon who can be of use, as it is resistant to Fighting- and Water-type attacks and immune to Ground-type attacks. Both of these Pokemon have instant recovery moves, so Regirock can form a solid defensive core with them. Mismagius can take advantage of Regirock's ability to lure Ground- and Fighting-type attacks, as it can switch into them with impunity. Weezing also makes a great partner as it resists Regirock's Grass- and Fighting-type weaknesses, and is immune to Ground-type attacks. Wish support is greatly appreciated because of Regirock's lack of a reliable recovery move. Chansey makes a good Wish passer to pair with Regirock, as it lures out physical attackers for Regirock to switch into. Leafeon makes a decent alternative Wish passer, possessing great defensive synergy with Regirock. With Explosion, Regirock can punch some major holes in the opponent's team, allowing another Pokemon to sweep. Bulky Water-types like to switch into Regirock and attempt to force it out with STAB Surf. However, Regirock can absorb the Surf and Explode, eliminating said bulky Water-type. Pokemon such as Dragon Dance Feraligatr and Azumarill benefit greatly from these Pokemon being removed from the battle, and thus make good partners for Regirock.

As a Rock Polish user, Regirock can work in two different ways. On the one hand, Regirock can play exactly the same as Rock Polish Rhyperior and Torterra as an offensive late-game sweeper. On the other hand, Regirock can also lure in its main counters, Milotic and other bulky Water-types, and blow them away with Explosion, opening the door for another sweeper to come in and finish the job. For the other two slots, Stone Edge and Earthquake come together to form the famous EdgeQuake combo, giving Regirock almost perfect neutral coverage in UU outside of Torterra and Claydol. If using Regirock as a sweeper, an Adamant nature and Life Orb are recommended in order to give Regirock as much power as possible. If using Regirock as a lure, a Jolly nature and Passho Berry are recommended instead to guarantee that Regirock outpaces Milotic, survives Surf or Hydro Pump if need be, and eliminates it with Explosion. Regirock literally doesn't have anything else worth using in the last slot besides Explosion. Superpower or Brick Break could be used to gain super effective coverage on Normal-types, but most times Stone Edge and Earthquake will be sufficient, and Regirock really doesn't like the power drop from Superpower. If you're not planning on Exploding Regirock at the first sign of a bulky Water-type, teammates who can eliminate them in a cleaner manner are recommended. Venusaur is a great teammate to switch into Water-types and blast them with a super effective Leaf Storm; Venusaur is also a good answer to both Claydol and Torterra, who resist both Stone Edge and Earthquake. Stealth Rock and Spikes support are also appreciated to pick up Regirock a couple of secured KOs against bulkier threats. With both forms of support, Life Orb Regirock can easily 2HKO Milotic with Stone Edge. Cloyster and Qwilfish can both provide Spikes support while Uxie and Miltank are both good options for Stealth Rock. Finally, if you decide to blast Milotic with Explosion, then a teammate who can capitalize on its absence is crucial. Dragon Dance Feraligatr and Choice Band Azumarill can both wreck teams without a bulky Water-type, as can Blaziken and Arcanine.

This set abuses Regirock's bulk to set up for a late-game sweep. With its excellent defenses, aided by RestTalk recovery, Regirock will have no trouble setting up Curse. After a couple of Curses, the opponent will likely not be able to KO Regirock with any Pokemon who can survive a boosted Rock Slide. This set reaches its full potential in a sandstorm, especially as the last Pokemon standing so that it can't be forced out. With incredible Defense as well as decent Attack and Special Defense, Regirock can set up six Curses quite easily and sweep your opponent's team. Rock Slide is chosen as the single attack due to its high PP, whereas Stone Edge might be more powerful but runs out too quickly. Since Regirock already boasts an insane Defense stat, Regirock's EVs should be put into Special Defense and HP (its Special Defense also receives a boost from sandstorm). Leftovers is the preferred item, but Chesto Berry allows Regirock to instantly wake up upon using Rest, allowing it to sweep and prevent itself from becoming setup fodder. This variant of Regirock needs a Pokemon who can set up permanent sandstorm. Without sandstorm in play, Regirock struggles to take powerful special hits. Unfortunately, Hippopotas is the only option in UU. This Regirock has trouble against Steelix and Donphan, who have great Defense, STAB Earthquake, and Roar to force Regirock out. Pokemon such as Nidoking, Magmortar, and Blaziken can OHKO Steelix, Donphan, and other walls who may be in Regirock's way; however, Magmortar and Blaziken lack sandstorm immunity, so Nidoking is preferred. Unfortunately, all three share an Earthquake weakness with Regirock. Haze Milotic is a big nuisance to Regirock, as it prevents it from setting up. Venusaur makes a fantastic partner, as it can easily switch in on Milotic and threaten it with STAB Grass-type attacks. Regirock should be wary of setting up until Encore and Trick users have been eliminated. Common users of these moves include Alakazam, Clefable, and Uxie. Drapion with Pursuit can be a great partner due to its ability to eliminate common Psychic-type Trick users, and can set up Toxic Spikes to aid Regirock's sweep. Drapion may also utilize Taunt and wear down Clefable as well.

Physical attacking Regirock aims to hit its usual counters hard with boosted attacks. Stone Edge nails any Pokemon who doesn't resist it, and deals respectable damage even when resisted. Earthquake and Ice Punch hit Steel-types and Ground-types, respectively. When Regirock has run its course, Explosion makes sure it takes out another Pokemon before it bites the dust. Stone Edge is Regirock's main STAB attack, and will dent almost everything that does not resist it. Earthquake is a nice coverage move which hits Steelix for super effective damage and also takes care of Registeel quite easily. Ice Punch is there to KO Pokemon such as Torterra and Claydol, who completely wall Stone Edge and Earthquake. A boosted Explosion is extremely powerful, easily KOing any wall without a resistance or immunity to it. Regirock takes advantage of Pokemon such as Houndoom and Arcanine who give Regirock a free opportunity to switch in. Venusaur is probably the best partner for this Regirock set, as it lures these Fire-types, and is also able to take hits from the bulky Water-type Pokemon who give this set trouble. With Houndoom and Arcanine out of the way, Grass-types and Pokemon susceptible to priority, such as Alakazam or Absol, have a much easier time sweeping.

Sunny Day Regirock is a surprisingly sound strategy; it reduces the damage Regirock takes from Water-type attacks, allowing it to actually beat several of its typical switch-ins, open up a sweep for a Fire-type, such as Typhlosion, or a Chlorophyll user, such as Victreebel, as well as boost the offensive prowess of its teammates in general. In addition to this, Regirock makes a great Stealth Rock supporter, which further facilitates the sweep of said teammates. Regirock is also a fine switch-in to the Fire- and Flying-types that usually trouble a team that revolves around the harsh sunlight, and can quickly dispatch them with its STAB Rock-type attacks. Ghost-types intending to switch into Explosion are also made wary because of its powerful STAB moves. A Heat Rock is the item of choice, prolonging the effects of Sunny Day, and giving Regirock's teammates the best chances of success. The EV spread is simple; HP is maximized for bulk, Attack EVs ensure that Milotic is always OHKOed by Explosion, and the rest are sent into Special Defense for some added leeway against special attackers such as Houndoom. A dedicated specially defensive spread can be used so that Regirock has the bulk to repeatedly set up Sunny Day throughout the match. If such a spread is used, it is recommended that you replace Explosion with Earthquake, as it would be a bit wasteful to just blow up that much beef... err rock. Fire-types, Chlorophyll users, and basically any Pokemon that can benefit from Sunny Day make great teammates to Regirock. Tangrowth deserves special mention for its ability to switch into Donphan, opposing Regirock, and Rhyperior with ease. Typhlosion and Arcanine are amazing partners as well, as both of them benefit from the removal of Water-types such as Milotic and Azumarill, making a potent Choice set much more viable.
