Mega Blastoise Raid Counters Guide

Mega Blastoise

Mega Blastoise is a pure Water-type Mega Raid Boss in Pokémon GO. Top counters include strong Electric and Grass-type Pokémon.

Note: You cannot catch Mega Blastoise in its Mega form. After the raid, you’ll encounter a regular Blastoise, and the following CP values apply to the base form:

• 1338 – 1409 CP (Level 20, no weather boost)
• 1673 – 1761 CP (Level 25, boosted by Rainy weather)

For an efficient win, we recommend 3–5 high-level trainers with strong counters. If your team is lower-level or lacks ideal Pokémon, bring additional friends to ensure success.

This guide covers everything you need to defeat Mega Blastoise: best counters, CP values, optimal moves, and more.

Mega Blastoise Overview

Mega Blastoise is a strong Water-type Pokémon that has a great mix of offense and defense, and only two weaknesses, making it a tricky raid. Nonetheless, with powerful counters and dodging (if Mega Blastoise uses Ice Beam against your Grass-type counters), the raid would be a success.

How to Get Mega Blastoise

In order to get Mega Blastoise, you will need 200 Mega Energy for the initial evolution.

Once you Mega Evolve a Pokémon for the first time, Mega Energy will no longer be required for that specific Pokémon to Mega Evolve again. Instead, the Pokémon will become exhausted after its Mega Evolution and need to rest before being Mega Evolved again. In other words, there is now a cooldown period after you Mega Evolve a Pokémon.

You can level up your Mega Pokémon in order to decrease this cooldown period. You can use more energy to end the cooldown period early.

Shiny Blastoise and Mega Blastoise

You can catch the shiny version of Blastoise from a raid, or catch a wild shiny Squirtle and evolve it. To obtain shiny Mega Blastoise, you need to Mega Evolve a shiny Blastoise.
