PvE / PvP / Raid Use

PvE (Raids)

• Strong Water attacker if maxed
• Competes with Gigantamax Inteleon-tier Water attackers but usually falls behind

PvP

• Rarely used directly in Gigantamax form
• Regular Blastoise (with Hydro Cannon) is more practical

Raids

• Acts more as a stall boss than DPS threat

Common Raid Mistakes

• Using Fire-type attackers
• Not bringing Electric coverage
• Ignoring weather boost advantage
• Underestimating its bulk

Evolution Line

• Squirtle → Wartortle → Blastoise → Gigantamax Blastoise
• Requires Blastoise + Gigantamax capability

Is Gigantamax Blastoise Worth Raiding?

Gigantamax Blastoise is situationally worth raiding, but it is not a top “must-farm” Gigantamax unless you specifically need collection value or a bulky Water-type option.

When It IS Worth Raiding

Collection / Dex Completion

• Gigantamax forms are rare event-exclusive content
• Good for “survive longer” raid roles

Event Bonus Value

• During boosted Gigantamax events:
  • Higher shiny chance
  • Easier raid lobbies
  • Extra rewards

When it’s NOT worth raiding

Better Water Attackers Exist

• Outclassed by top Water attackers like:
  • Gigantamax Kingler-tier Pokémon
  • Other high-DPS Water attackers

Limited PvP Value

• Gigantamax form is generally not practical in PvP formats
• Regular Blastoise (with Hydro Cannon) performs better there

Resource Efficiency

• Takes more time and players due to tanky raid style
• Not the fastest reward-per-raid option

Final Mode Comparison

Evolution & Mega Potential — Gigantamax Blastoise

Gigantamax Blastoise comes from the classic Squirtle line, but its Gigantamax form does NOT change its evolution path or unlock Mega Evolution at the same time. These are separate mechanics.

Evolution Line

Base Line

• Squirtle → Wartortle → Blastoise

Final Evolution

• Blastoise is the final evolution stage
• After evolving, it can access:
  • Gigantamax form
  • Mega Evolution

Gigantamax vs Mega Evolution

Gigantamax Blastoise:

• Temporary battle transformation
• Used in Max Raid / Gigantamax battles
• Changes appearance + gives G-Max Cannonade
• Does NOT permanently change stats

Mega Blastoise:

• Permanent battle transformation
• Requires Mega Energy
• Boosts Water-type damage permanently during Mega time window
• Better for PvE raid attacking

Can It Have Both?

Yes — but not at the same time:

• Gigantamax = special raid form only
• Mega Evolution = combat power boost form
• You choose one per battle system

Mega Blastoise Potential

Strengths:

• High Water-type DPS boost
• Strong raid attacker role
• Improves team Water damage output

Weaknesses:

• Still outclassed by top Water raid attackers in raw DPS
• No Gigantamax mechanics in Mega form

Gigantamax vs Mega Use Case

Which is Better?

For Raids:

• Mega Blastoise is better for damage output

For Events / Gigantamax Battles:

• Gigantamax Blastoise is required for that content
