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.

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)

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.
