Quick summary
Overview
Blastoise’s Gigantamax form amplifies its role as a Water-type tank: massive HP pool, strong water STABs (e.g., Hydro Pump / Origin Pulse analogues) and potential secondary coverage like Ice Beam or Flash Cannon in event variants. In raid fights, expect longevity—clear time comes down to efficient sustained damage, energy economy, and smart shield use. While purely Water strong counters dominate, be ready for mixed coverage if the charged-move preview shows secondary types.
Pro tip: For Gigantamax Blastoise, Hydro-based boss moves reward Ground-lite thinking only in rare variants; primarily stack Electric and Grass counters unless preview shows Ice/Steel moves.

Moves & Threats
Blastoise common fast moves are Rollout or Water Gun and Bite. Charged moves include Skull Bash or Flash Cannon or Hydro Pump and Ice Beam. Elite moves include Hydro Cannon. G-Max Cannonde not only delivers heavy damage but also leaves a damaging area for a short time — timing your swaps and using at least one bulky support reduces wipe risk.
Weather Effects & Battle Flow
Rainy weather : boosts Blastoise Water moves. Sunny weather : boosts Grass attackers.
Watch for Ice Beam, which punishes Grass-type counters heavily. Balance your team with Electric attackers.
Battle Tips
- Front-load your best Electric/Grass DPS to capitalize on early damage windows.
- Coordinate dodges only on heavy Max Moves — constant dodging reduces overall DPS in long fights.
- Star and favorite teams to reduce relobby time; players in large groups should communicate role.
Size
Recommended: 15–20 trainers for comfortable clears with mixed player levels. With many Gigantamax / Dynamax counters, 10–14 can work. Under 8 trainers should be attempted only if all participants are high-level and coordinated with ideal counters and Mega/Dynamax/G-Max boosts.
Rewards
Reasons include Pokédex entry, strong Water attacker, shiny chance, and XL Candy farming.
When To Avoid
Avoid Ground, Fire, and Rock Pokémon — they take heavy damage from Blastoise’s Water moves.
Raid Strategy & Catch Tips
Gigantamax Blastoise’s bulk makes raids tough. Focus on Electric types for consistent damage, with Grass support when Ice Beam isn’t in play. Dodge G-Max Cannonade’s chip damage to extend survival.
