Mega Blastoise has long been a fan-favorite in Pokémon battles, and in Pokémon Legends: Z-A, its potential is even more pronounced with the Hydro Cannon build. This guide will walk you through how to maximize Mega Blastoise’s offensive capabilities while maintaining strategic versatility.
Why Choose Hydro Cannon?
Hydro Cannon is arguably Mega Blastoise’s most powerful move when fully charged. Its incredible Water-type damage allows you to target Fire, Rock, and Ground types effectively. Pairing this move with Mega Blastoise’s impressive Special Attack stat makes it a devastating choice in both PvE encounters and competitive matches.
Recommended Moveset

1. Hydro Cannon – Your primary damage dealer. Make sure to optimize Mega Blastoise’s EVs to enhance Special Attack for maximum impact.
2. Ice Beam – Provides coverage against Grass and Dragon types that would otherwise resist Water attacks.
3. Dark Pulse – Useful for Psychic and Ghost Pokémon that may challenge Blastoise in battle.
4. Rapid Spin – Helps clear entry hazards and ensures your team maintains momentum.

This moveset balances raw power with utility, allowing Mega Blastoise to remain a threat in multiple scenarios.
Optimal Stats and EV Distribution

• Special Attack: Maximize this stat to boost Hydro Cannon’s damage.
• Speed: Moderate investment to outspeed threats like other Water-types or faster Electric types.
• HP & Defense: Allocate remaining EVs here to improve survivability.

Nature-wise, Modest or Timid are both strong options depending on whether you prefer raw damage or better speed control.
Battle Strategy
Start by assessing the battlefield. Mega Blastoise thrives when it can charge Hydro Cannon safely. Using teammates to switch in on resistant types or set up hazards can give you the opening needed to unleash devastating Water-type attacks. Pairing with Electric-immune allies also ensures you’re less likely to be countered.
