Gigantamax Blastoise is making itsPokémon GOdebut in Max Raid Battles, meaning you can battle and potentially catch this powerful creature to add to your collection. Gigantamax Pokémon are expected to be the most challenging opponents in the game, so it’s important that you come prepared with a team of strong counters that can target Blastoise’s weaknesses.
Arriving alongside Gigantamax Charizard and Gigantamax Venusaur as part of the GO Bigger event, Gigantamax Blastoise will be appearing in six-star Max Raid Battles atPower SpotsfromOctober 26 to June 17, 2025. You’ll most likely need to team up with at least 10 other Trainers for a chance of victory, although the maximum number of entrants is 40, so the more Trainers you can participate with, the better.
Gigantamax Blastoise Weaknesses & Resistances
There Are Two Vulnerabilities You Need To Target
Gigantamax Blastoise is a Water-type Pokémon, which meansits only weaknesses are Electric and Grass-type attacks. Given the limited number of Dynamax-capable Pokémon that are available inPokémon GOright now, your best option is to focus on Grass-type Pokémon with Grass-type movesets.
On the other hand, Gigantamax Blastoiseis resistant to Fire, Ice, Steel, and Water-type attacks. Avoid using these move types wherever possible, as they won’t deal much damage. That rules out the likes of Blastoise and Charizard – only run these on your team if they’re the only Dynamax-capable Pokémon you have.
Best Counters For Gigantamax Blastoise
Grass-Type Dynamax Pokémon Are Best
The best counters for Gigantamax Blastoise areDynamax Venusaur and Dynamax Rillaboom, as these are the strongest Dynamax-capable Pokémon with both a Fast Attack and a Charged Attack that can target Blastoise’s weaknesses.
For Dynamax Venusaur, you’ll want to runVine Whip and Frenzy Plant. For Dynamax Rillaboom, you’ll want to runRazor Leaf and Grass Knot. All of these moves will benefit from STAB (Same-Type Attack Bonus), which grants some extra damage, but most importantly, they’ll give both Pokémon a Grass-type Max Move to use when Dynamaxed in battle, which is the key to overcoming Gigantamax Blastoise.
Remember that only Dynamax Pokémon and Gigantamax Pokémon can take part in Max Raid Battles.
My next recommendation to take into battle against Gigantamax Blastoise would beDynamax Greedent. Although it’s not a Grass-type Pokémon, it does have access to a complete Grass-type moveset: Bullet Seed and Trailblaze. This lets it deal super-effective damage and unleash a Grass-type Max Move when Dynamaxed, which gives it an advantage over some of the other Dynamax-capable Pokémon in the game.
If you don’t have any of those Pokémon in your collection, choose the three most powerful Dynamax-capable Pokémon you own and hope for the best! A good choice would be something likeDynamax GengarorDynamax Metagross. While these Pokémon can’t target any of Gigantamax Blastoise’s weaknesses inPokémon GO, they areverystrong in general, which will hopefully be enough to see you through the battle.
