Slowbro (Mega)

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

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.

Mega Slowbro Counters

Since Shadow Pokémon are extremely expensive to power up and require specific events to remove Frustration with a Charge TM, they will NOT be listed as raid counters in this article. That being said, if you have the shadow form of a listed raid counter Pokémon powered up and TMed, use it.

Let’s check out the top raid counters for Mega Slowbro:

Mega Slowbro Counters
The supreme Mega Slowbro Raid Counters
Gengar (Mega) Shadow Claw Ghost Shadow Ball Ghost
Gyarados (Mega) Bite Dark Crunch Dark
Great Mega Slowbro raid counters
Houndoom (Mega) Snarl Dark Foul Play Dark
Darkrai Snarl Dark Shadow Ball Ghost
Chandelure Hex Ghost Shadow Ball Ghost
Zekrom Charge Beam Electric Wild Charge Electric
Electivire Thunder Shock Electric Wild Charge Electric
Giratina (Origin) Shadow Claw Ghost Shadow Ball Ghost
Ampharos (Mega) Volt Switch Electric Zap Cannon Electric
Magnezone Spark Electric Wild Charge Electric
Thundurus (Therian) Volt Switch Electric Thunderbolt Electric
Raikou Volt Switch Electric Wild Charge Electric
Venusaur (Mega) Vine Whip Grass Frenzy Plant Grass

While the Pokémon stated above are the generic counters, Mega Slowbro’s dual typing of Water and Psychic flips the tables on different occasions. For instance, the top counter, Mega Gengar, is weak to Mega Slowbro’s STAB Psychic moves. This applies to something like Mega Venusaur as well. So you should mega evolve either Gengar or Venusaur only if Mega Slowbro isn’t using Psychic moves.

A similar logic follows when Mega Slowbro is using Water types moves and you should be wary of using Mega Houndoom or Chandelure.

How to get Mega Slowbro?

You cannot catch Slowbro in its mega evolved form from the raid. The mega raid boss is always catchable in its base form and as such, the CP ranges are for a regular Slowbro.

Slowbro can be caught with the following CP values:

  • 1382- 1454CP at level 20, no weather boost
  • 1728- 1817 CP at level 25 with Rainy or Windy weather boost

Mega Slowbro Stats

As it is quite evident, Mega Slowbro is very bulky and as such, we had focused our list of counters on Time To Win complemented with raw DPS.

With that being said, let us check out Mega Slowbro’s movepool!

Mega Slowbro Moveset Analysis

Fast Moves Charge Moves
  • Water Gun Water
  • Confusion Psychic
  • Water Pulse Water
  • Psychic Psychic
  • Ice Beam Ice

Confusion is an extremely hard-hitting STAB move with low energy gains. While this will demolish Mega Gengar, your Dark types will resist it.

Water Gun might not hit as hard as Confusion but charges quicker and is largely unresisted by your counters.

Psychic and Water Pulse are both 2-bar STAB charged moves that can come quite frequently from Water Gun. Psychic is the more damaging move.

Ice Beam lacks STAB and with Mega Slowbro’s relatively lower ATK stat, it shouldn’t really be concerning.

Mega Slowbro is a fun Mega to add to your roster of Pokémon. It looks hilarious, has an amazing shiny and is very bulky thereby, is instrumental in giving the coveted Mega Bonus to Water and Psychic Pokémon in raids for a long period of time.

Stay safe and all the best, trainers!
