With the most effective raid counters, you can quickly win against Mega-Slowbro in Pokémon GO. We have summarized for you the best attackers and all the important information about Mega-Slowbro.
What kind of boss is it? The Mega Evolution of Slowbro is of the Water and Psychic type. It was first introduced on June 8, 2021 as part of the event “A Very Slow Discovery” in Pokémon GO.
As with all other Mega Raids, you cannot catch the Mega Evolution directly at the end, but you receive a regular Slowbro. With the corresponding Mega Energy, you can then evolve this Mega monster from Slowbro. The required Mega Energy for Mega-Slowbro is obtained as a reward at the end of the Mega Raids.
How long can you fight against Mega-Slowbro? You can find the raid boss from June 8, 2021, at 10:00 AM to June 17, 2021, at 10:00 AM in the Mega Raids in Pokémon GO.

Notes: Mega-Slowbro is particularly vulnerable to Electric and Grass attacks due to its Water type. If the raid boss uses Psychic attacks, then Pokémon with counters from the Dark, Ghost, or Bug areas will also be very effective.
If you do not have the mentioned Mega or Shadow Pokémon, you can also use common Pokémon alongside Darkrai and Zekrom. Pokémon like Chandelure, Giratina (Altered Form), Snorlax, and Gengar with their Ghost and Dark attacks are also effective against Mega-Slowbro, as are Raikou, Electivire, and Magnezone with their Electric attacks.
If the weather is windy or rainy during the raid, Mega-Slowbro also receives a weather boost. When catching, the CP value therefore ranges between 1,382 CP and 1,454 CP (without weather boost) or between 1,728 CP and 1,817 CP (with weather boost).

The raid boss can have various attacks, which are composed as follows:
As a Fast Attack, Mega-Slowbro learns Confusion or Water Gun
As a Charged Attack, it learns Ice Beam, Psychic, or Hydro Pump
How many trainers do you need to defeat Mega-Slowbro? To bring this raid boss down quickly, we recommend a battle with at least four trainers.
