Gigantamax Blastoise

Like its base Dynamax form, Gigantamax Blastoise functions primarily as a tank to make use of its high Defense stat, and should prioritize leveling up Max Guard and Max Spirit. Though G-Max Cannonade is a powerful move, it is often not GMax Blastoise's main option, though it can put in work when it has nothing better to click.

As an attacker, Dynamax Inteleon has a a whopping 53% Attack lead over Blastoise, while G-Max Cannonade is only about 28% stronger than Max Geyser when both are at max level. When you want to rely on pure damage, Inteleon still outperforms GMax Blastoise. In the future, Gigantamax Inteleon will be released, further widening the offensive gap between them.

Best PvE Offensive Movesets

• Gigantamax Blastoise is locked into a Water Type moveset, even more so than its basic, Shadow, and Mega Formes due to the way that Max Moves work. For this reason, pairing Water Gun with Hydro Cannon* is what currently allows Gigantamax Blastoise to remain competitive.
• Hydro Pump is a good backup if you don't want to utilize an Elite TM.

In PvP, Gigantamax Blastoise is effectively no different from a normal Blastoise, except without access to Return as a move option.
