Struggling to beat Regirock in Pokémon GO? Learn how to win with the best counters, weaknesses, and CP data. Plus, find out how to get your Shiny Regirock!
Regirock has returned to five-star raids for the Ancients Recovered event of April 2026, and it remains one of the most polarizing bosses in the game. While its offensive pressure is manageable, its colossal 309 Defense stat makes it the undisputed “Tank King” of the Regi Trio.
Because of this massive defense, Regirock absorbs damage like a sponge, making it a major “Time-Out” risk for small groups. To succeed, you need more than just the right types; you need high-level DPS (Damage Per Second) and optimized TTW (Time To Win). While a duo is technically possible, it is considered “Whale Territory,” requiring Level 50 Shadow/Mega counters, Best Friend bonuses, and perfect weather. For most trainers, a group of 4–7 trainers is the sweet spot to ensure a win without burning through your stash of Max Revives.
Regirock Weakness, Resistance, and Weather Strategy
Regirock is a pure Rock type. To shatter its 309 Defense, you must exploit its five primary weaknesses: Fighting, Steel, Ground, Water, and Grass. Conversely, you must AVOID bringing Fire, Flying, Normal, or Poison types, as Regirock resists these, effectively cutting your damage output by nearly 40%.
Strategic trainers will also use the weather to their advantage. Cloudy weather is the gold standard, as it boosts Fighting-type attackers. Rainy or Sunny weather can make Water and Grass types viable, respectively. However, be wary of Partly Cloudy conditions; while it increases the catch CP, it also boosts Regirock’s Rock-type moves, making the raid significantly more difficult.
The S-Tier Counter List (2026 Meta)
The 2026 season has reshuffled the leaderboard. While Metagross was once the king, new “Crowned” and “Dusk Mane” forms now dominate.
Pro-Tip: Don’t just look at the highest DPS—focus on TTW. Crowned Sword Zacian can finish the raid nearly 100 seconds faster than standard counters.
| Rank | Pokémon | Fast Move | Charged Move | Role |
| #1 | Crowned Sword Zacian | Metal Claw | Behemoth Blade | The King: Unbeatable TTW. |
| #2 | Mega Lucario | Force Palm | Aura Sphere | DPS Peak: Highest raw damage. |
| #3 | Dusk Mane Necrozma | Metal Claw | Sunsteel Strike | The Wall: Phenomenal bulk. |
| #4 | Primal Groudon | Mud Shot | Precipice Blades | Ground Lead: Team boost. |
| #5 | Shadow Metagross | Bullet Punch | Meteor Mash | Steel Specialist: Elite Shadow. |
Advanced Mechanics & Strategies: The “Silph Road” Edge
To conquer Regirock with fewer players, you must avoid “Aggron Syndrome”—using “Recommended” teams that prioritize survival over damage. Instead, utilize advanced tactics popularized by The Silph Road community on Reddit.
- The “Catch Tanking” Technique: Regirock’s Focus Blast and Earthquake can one-shot many counters. Catch Tanking involves watching the boss animation; when the text “Regirock is using Focus Blast” appears, immediately swap to a resistant “Tank” (like Crowned Shield Zamazenta or Lugia) to soak the hit, then swap back to your DPS dealer.
- The Move Reroll Strategy: Focus Blast is the #1 reason for team wipes. If you enter a lobby and find Regirock is using this move, it may be worth “re-lobbying” to see if the move RNG resets to an easier attack like Zap Cannon or Stone Edge.
- The 0.5s Fast Move Rule: Energy generation is key to breaking high defense. Pokémon with 0.5-second fast moves (like Water Gun or Psycho Cut) allow you to dodge more effectively and charge your powerful moves faster.
- Dynamax & Max Battles: For Dynamax Regirock, use a Healer/Tank/Attacker Triad. Lead with Dynamax Blissey for healing, switch to Crowned Shield Zamazenta to draw aggro and stack shields, and finish with GMax Inteleon during the final Max Phase.
Regirock CP & Shiny Guide
Catching a high IV Regirock is the ultimate goal. Keep these numbers in mind to identify a perfect 100% IV catch:
- Standard (Level 20): 1784 CP
- Weather Boosted (Level 25): 2230 CP
If you are lucky, you may encounter a Shiny Regirock, which features a distinct chocolate-brown/deep copper color. The shiny odds for legendary raids remain approximately 1 in 20, so persistence is necessary.

A: For your own Regirock, Lock-On (fast energy) paired with Stone Edge and Earthquake is the best moveset for PvP and gym defense.
