Weaknesses of Mega Blastoise: The Mega Evolution is a Water-type Pokémon, which means it is weak against attacks from Grass and Electric types. You should definitely use this in battle and deploy appropriate monsters.
Is there a Shiny Blastoise? Yes, with a little luck you can catch a Shiny Blastoise after the raid. You can recognize it by its purple body.
How many trainers are needed? To defeat Mega Blastoise, two trainers are usually sufficient for experienced players. However, note that you should rely on the top attackers and ideally have a trainer level over 40. We therefore recommend bringing a few friends along. This will make the raid a bit more relaxed.
