Mega Slowbro Raid Guide

Mega Slowbro

Mega Slowbro is a Water and Psychic type Mega Raid Boss. Optimal raid counters include powerful Bug, Dark, Electric, Ghost, and Grass types. With such a diverse range of weaknesses, it would be relatively easy to take out Mega Slowbro.

After the raid, you’ll encounter a regular Slowbro, and the following CP values apply to the base form:

• 1382 – 1454 CP (Level 20, no weather boost)
• 1728 – 1817 CP (Level 25 with Rainy or Windy weather boost)

Depending on your levels and counters, we would recommend 3-6 high-level trainers who or more if you don’t have optimal teams. This is attributed to the fact that Mega Slowbro is quite bulky.

This guide will tell you how to beat this awkward Mega almost completely stuck inside a Shellder. In addition, we will also present its stats, moves, and CP range.

How to Get Mega Slowbro

In order to get Mega Slowbro, 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 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.
