Who is Regirock in Pokémon Go?

Pokemon 377 RegirockSource: The Pokémon Company

Regirock is one of the Legendary Titans, six golem-like Pokémon with a single type each. The first three, Regirock, Regice, and Registeel were originally encountered in the Hoenn region of Gen III. The fourth, Regigigas, didn't show up until the Sinnoh region of Gen IV, and two more, Regielecki and Regidrago were introduced in the Crown Tundra DLC for Pokémon Sword and Pokémon Shield.

In Pokémon Go, the Regi's high defense and Legendary status really limit their usefulness. Still, with the introduction of more Mega Pokémon and lots of new Shadow Pokémon, there are a number of winning strategies for Trainers who can coordinate these Raids.

What are the best counters for Regirock in Pokémon Go?

As a pure Rock type, Regirock takes double damage from Fighting, Ground, Steel, Water, and Grass type attacks. It is capable of dealing Rock, Fighting, Normal, and Electric type damage. If it is possible to do so safely, coordinate with your fellow Raiders to focus on Water or Grass types with Mega Blastoise or Mega Venusaur and you'll be golden. If you cannot coordinate safely or don't have the Mega Energy to spare, there are still plenty of winning teams.

Mega Blastoise

The Mega Evolution of Gen I's Water starter, Mega Blastoise is the number one non-Shadow counter in this Raid, despite taking double damage from Regirock's potential move Zap Cannon. If you can match him up with teams of Water types, you will leave Regirock in shambles. Whether Mega, Shadow, or just standard, you'll want your Blastoise to know Water Gun and Hydro Cannon.


Pokemon 376 MetagrossSource: The Pokémon Company

Trailing only slightly behind Mega Blastoise is the pseudo-Legendary Steel and Psychic type, Metagross. Even though its Mega Evolution hasn't made its Pokémon Go debut (and Arceus help us when it does!) Metagross shines. It's Shadow variant actually out performs even Mega Blastoise. Metagross has no weaknesses that Regirock can exploit and it takes only half damage from Rock and Normal type attacks. Thanks to being featured in a number of events, Community Day, and as a Shadow Pokémon, most players have plenty already powered up. You'll want your Metagross to know Bullet Punch and the Community Day exclusive charged move, Meteor Mash.

Mega Venusaur

Another Mega Evolved starter, Mega Venusaur performs remarkably well against Regirock while boosting other Grass type attackers. A Grass and Poison type, Mega Venusaur doesn't have any weaknesses that Regirock can exploit and takes half damage from Fighting and Electric type attacks. Whether you're bringing a Mega Venusaur, Shadow Venusaur, or just the standard Venusaur, you'll want it to know Vine Whip and Frenzy Plant.

Mega Gyarados

Although Mega Blastoise performs considerably better, Mega Gyarados is still a beast in this Raid. As a Water and Dark type, it takes increased damage from Electric and Fighting type attacks, so it doesn't last quite as long, but it will still boost the other Water type Pokémon on the field. If you are bringing Mega Gyarados to this fight, you'll want it to know Waterfall and Hydro Pump.


Pokemon 534 ConkeldurrSource: The Pokémon Company

A Fighting type introduced in the Gen V Unova region, Conkeldurr performs great against Regirock in a vacuum. It takes half damage from Rock type attacks and has no weaknesses the Rock Titan can exploit. However until we get a Mega Evolved Fighting type, Conkeldurr should only be brought to this Raid if you can't coordinate using Mega Blastoise or Mega Venusaur. Conkeldurr's first stage, Timburr has become a little more common, being featured in Raids and during events, and Conkeldurr benefits from Trade Evolution, leaving lots of extra Candies for powering up. Counter and Dynamic Punch is the moveset you'll want your Conkeldurr to know for this fight.


Pokemon 448 LucarioSource: The Pokémon Company

Originally encountered in the Sinnoh region of Gen IV, Lucario also performs well against Regirock in a vacuum. Once Lucario or Metagross have their Mega Evolutions unlocked, both will out perform Mega Blastoise, but until then, Lucario is great if you can't coordinate for the Mega boost. Lucario takes half damage from Regirock's Normal attack and quarter damage from its Rock type attacks, but double damage from its Fighting type attacks. Unfortunately, the only way to get Lucario is by evolving its baby stage, Riolu and Riolu is incredibly rare, only hatching from a select few Eggs. Still, if you have Lucario, Counter and Aura Sphere is the moveset you'll want it to know.

Landorus (Therian forme)

One of the Unovan Forces of Nature, Landorus is a Legendary Pokémon with multiple formes. For this Raid, you'll want the newer Therian forme. Fortunately, both formes use the same Candy and Landorus has been in Raids a number of times, as well as featured as a Pokémon Go Battle League reward encounter. As a Ground and Flying type, it has no weaknesses Regirock can exploit and it resists both Electric and Fighting type attacks. Mud Shot and Earthquake is the moveset you'll want your Landorus to know for this fight.


Pokemon 286 BreloomSource: The Pokémon Company

Gen III's Breloom is another great counter for Regirock capable of hitting two weaknesses. As a Grass and Fighting type, it resists Electric and Rock type damage, while having no weaknesses relevant to this fight. Its first stage is a relatively common spawn and it only costs 50 Candy to evolve, making it very accessible. In a vacuum, Counter and Grass Knot are the best moves for Breloom in this Raid, but Bullet Seed pairs well with the Mega stat boost from Mega Venusaur. Alternatively, if someone brings Mega Lopunny, Dynamic Punch could outperform Grass Knot.


Pokemon 445 GarchompSource: The Pokémon Company

Thanks to its Community Day exclusive move, Garchomp is now a top counter for Regirock. Also thanks to its Community Day, as well as a few other events, most players have added Garchomp to their roster. As a Dragon and Ground type, it resists Rock and Electric damage, and has no weaknesses Regirock can exploit. Mud Shot and Earth Power are the moves you'll want your Garchomp to know for this Raid.


Pokemon 382 KyogreSource: The Pokémon Company

The Legendary Mascot of Pokémon Sapphire, Kyogre does great against Regirock, especially when boosted by Mega Blastoise. As a pure Water type, Kyogre does take double damage from Zap Cannon, but isn't weak to the rest of Regirock's attacks. It's also been available many times so most Trainers already have at least one powered up. Waterfall and Surf is the moveset you'll want your Kyogre to know for this Raid.

Back ups?

Although most players will be able to make a team of the best counters, if you're finding a gap in your team, there are plenty of back ups who work well in larger groups. Just make sure you're dodging and any of the following could be a decent back up:

  • Groudon with Mud Shot and Earthquake
  • Empoleon with Metal Claw and Hydro Cannon
  • Swampert with Water Gun and Hydro Cannon
  • Excadrill with Mud-Slap and Drill Run
  • Landorus (Incarnate forme) with Mud Shot and Earth Power
  • Dialga with Metal Claw and Iron Head
  • Machamp with Counter and Dynamic Punch
  • Mega Gengar with Lick and Focus Blast
  • Mega Lopunny with Low Kick and Focus Blast
  • Kingler with Bubble and Crabhammer
  • Feraligatr with Water Gun and Hydro Cannon
  • Roserade with Razor Leaf and Grass Knot
  • Genesect with Metal Claw and Magnet Bomb
  • Rhyperior with Mud-Slap and Earthquake
  • Haxorus with Counter and Surf
  • Sceptile with Fury Cutter and Frenzy Plant
  • Toxicroak with Counter and Dynamic Punch
  • Venusaur with Vine Whip and Frenzy Plant
  • Blaziken with Counter and Focus Blast
  • Hariyama with Counter and Dynamic Punch
  • Torterra with Razor Leaf and Frenzy Plant
  • Sirfetch'd with Counter and Leaf Blade
  • Clawitzer with Water Gun and Crabhammer
  • Tangrowth with Vine Whip and Power Whip

Shadow Pokémon

The rebalance of Shadow Pokémon rescued from Team GO Rocket make them excellent glass cannons. Not only are their stats boosted, but during special events or with Elite TMs, it's possible to change their moves. If you happen to have any of the following Pokémon with the right moveset, they will work very well in this Raid:

  • Shadow Metagross with Bullet Punch and Meteor Mash
  • Shadow Machamp with Karate Chop and Dynamic Punch
  • Shadow Swampert with Mud Shot and Hydro Cannon
  • Shadow Torterra with Razor Leaf and Frenzy Plant
  • Shadow Hariyama with Counter and Dynamic Punch
  • Shadow Tangrowth with Vine Whip and Power Whip
  • Shadow Venusaur with Vine Whip and Frenzy Plant
  • Shadow Exeggutor with Bullet Seed and Solar Beam
  • Shadow Alakazam with Counter and Focus Blast
  • Shadow Victreebel with Razor Leaf and Leaf Blade
  • Shadow Gallade with Low Kick and Leaf Blade
  • Shadow Mamoswine with Mud-Slap and Bulldoze
  • Shadow Scizor with Bullet Punch and Iron Head

Note: Shadow Metagross outperforms every other Pokémon in the best counters list. If you are able to coordinate the use of Mega Blastoise, Mega Gyarados, or Mega Venusaur, they will boost Water or Grass types respectively, making some Shadow Pokémon perform even better, and though Mega Lopunny isn't in the top counters, it will boost Fighting types on the field.

How many players does it take to beat Regirock in Pokémon Go?

With the best possible counters, two high level players can take out Regirock alone; however, if you're lacking the best counters or are a lower level, you may need four or five Trainers.

  • Cloudy weather will boost both Regirock's Fighting type attacks and your Fighting type counters.
