Overview

Regirock sports an amazingly high base 200 Defense, backed by an acceptable base 80 HP. It can take on some of the strongest physical attacks, even weaker super effective ones. Additionally, Regirock can make do with its base 100 Special Defense with EV investment while still maintaining most of its physical bulk. Rock is not an excellent defensive typing as it's weak to many common attacking types, such as Ground, Water, Grass, and Fighting; nonetheless, it grants Regirock a crucial resistance to Fire, which allows it to comfortably check many Fire-types, such as Moltres and Entei. Another of Regirock's flaws is its lack of any reliable recovery outside of Rest. Despite such drawbacks, Regirock is still a very sturdy and reliable defensive Pokemon in RU, and also one that can set Stealth Rock reliably and repeatedly when needed. Aside from being a generally good bulky wall to fall back on, Regirock finds its niche in stopping many Fire-types—specifically, it is one of the few counters to Moltres.

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 Hi 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.

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 ExtremeSpeed 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 SolarBeam 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.

Other Options

While Regirock's main niche is as a defensive Pokemon that can check many Fire-types, and even straight-up counter Moltres, it also has several other more offensive options to choose from. Drain Punch and Hammer Arm are viable Fighting-type attacks. Counter can be used as Regirock's titanic Defense virtually guarantees that it will not fall to any non-super effective physical attack. Curse is a possible boosting option, though Regirock's Rock typing does not really help in this regard as it is weak to many common attacking types. Strong support in removing Fighting-type attacks and other threatening foes will be needed to pull off a sweep. In most cases, Regirock will be better off supporting the team than receiving support. Rest, used in tandem with Chesto Berry or cleric support, is worth considering if your team has trouble dealing with Fire-types. Regirock can also work as an offensive tank with a spread of 252 HP / 252 Atk / 4 SpD and support the team with Stealth Rock and even Thunder Wave. Drain Punch, Stone Edge, and Earthquake are all usable on an offensive tank Regirock. It has a reduced ability to check Fire-types without Special Defense investment, however. Explosion with a type-resist Berry, such as Chople or Rindo Berry, allows Regirock to lure and take out Fighting-types such as Hitmonlee or Grass-types such as Sceptile, respectively.

Check and Counters

Fighting-types are a menace for Regirock: Poliwrath often has Rest to shrug off status while Guts Hariyama benefits from it. Steel-types have an easy time setting up on Regirock: Steelix can set up Stealth Rock and proceed to threaten with Earthquake, Klinklang can use Shift Gear if Regirock doesn't have Earthquake, and Escavalier and Durant can threaten directly with Iron Head, provided that Regirock does not have Fire Punch. Grass-types can also walk over Regirock without much difficulty; Sceptile can prey on Regirock's lower Special Defense, while Lilligant can either put down Regirock with Sleep Powder or use it as setup fodder should Lilligant have a Lum Berry. Defensive Water-types such as Slowking and Lanturn can safely wall Regirock, though the latter has to watch out for Earthquake. Slowking has Regenerator and fears only Toxic, while Lanturn sometimes carries Heal Bell to negate even that. Qwilfish can Taunt Regirock and set up entry hazards, but Earthquake dents it as Clear Body negates Intimidate. Offensive Water-types such as Kabutops and Omastar can set up on it, although Thunder Wave will badly cripple them. Ferroseed can set up directly on Regirock without Fire Punch. Regirock abhors status as it greatly reduces its ability to reliably fulfill its main purpose—checking Fire-types. A strong offensive presence coupled with status can sometimes be sufficient to stop a cleric from healing Regirock of status and allow said Fire-type to finally get past Regirock.

Unreleased

Regirock receives Sturdy as its Dream World ability. This is only a minor upgrade over Clear Body, as there isn't much in RU that can OHKO Regirock to begin with, but it's still an improvement. As long as the battlefield is free from entry hazards, Regirock can use Sturdy to work as an emergency check to Pokemon such as Sceptile and Feraligatr, surviving a hit and replying with Thunder Wave or Explosion. This gives Sturdy more utility than Clear Body, which rarely comes into play at all except to nullify Intimidate from Qwilfish.
