Here is a list of what we think are the best Water-type Pokemon in Pokemon GO, including their best movesets.

The best Water-type Pokemon are often those that possess high survivability along with decent attack power. If Fire-types specialize in raw damage, Water-types aim for balanced stats. Additionally, they offer wide coverage against enemies like Fire, Rock, and Ground-types, making them reliable in just about any situation.
However, you can’t just bring in a full team of Water-types and expect them to handle every opponent. You still need to consider their strengths and weaknesses. Whether you’re looking to participate in the GO Battle League, take on raids, or are simply an avid collector, here is our list of the best Water-type Pokemon in Pokemon GO.
8 Best Water-Type Pokemon in Pokemon GO
1. Primal Kyogre

- Type: Water
- Strengths: Unrivaled raw Water-type stats
- Weakness: Electric and Grass
- Best Moveset: Water Gun and Hydro Cannon
Primal Kyogre takes Kyogre’s already dominant performance and cranks it up to the max. With Waterfall and Origin Pulse, it delivers exceptional DPS. One important detail is that this Pokemon is the only Water-type that can learn the Electric-type move Thunder. This means you can keep a handy move that counters other Water-types if needed.
2. Mega Swampert

- Type: Water and Ground
- Strengths: Best Water-type attacker in the game, excellent typing
- Weakness: Grass
- Best Moveset: Water Gun and Hydro Cannon
Mega Swampert is a powerhouse. With Water Gun and Hydro Cannon, it dishes out incredible Water-type damage. Its secondary Ground typing provides key resistances and added coverage, making it especially dangerous against Fire and Electric-types. This Pokemon can also learn moves like Mud Shot and Earthquake. On top of that, Mega Swampert is relatively tanky, with significantly higher Stamina than Primal Kyogre.
3. Mega Blastoise

- Type: Water
- Strengths: Reliable raid attacker, high base stats
- Weakness: Electric and Grass
- Best Moveset: Water Gun and Hydro Cannon
Unlike the two previously mentioned Pokemon, Mega Blastoise serves a slightly different purpose. It may not boast the highest DPS, but it makes great use of the Same Type Attack Bonus (STAB). With Water Gun and Hydro Cannon, it performs well in raids—especially when you’re pressed for time. It’s also more accessible, making it a solid option for players with fewer choices.
4. Mega Gyarados

- Type: Water and Dark
- Strengths: High DPS, valuable dual typing
- Weakness: Bug, Electric, Fairy, Fighting, and Grass-type
- Best Moveset: Bite and Hydro Pump
Mega Gyarados features high attack stats and a useful Water/Dark typing, making it a strong counter to both Psychic- and Fire-types. While it doesn’t reach the dominance of Swampert or Kyogre, its Bite and Hydro Pump combo is efficient and reliable. It is known for delivering heavy damage, even when attacks aren’t super effective. However, it does come with several type weaknesses.
5. Mega Slowbro

- Type: Water/Psychic
- Strengths: Massive bulk, strong defensive play in PvP
- Weakness: Bug, Dark, Electric, Ghost, and Grass-type
- Best Moveset: Confusion and Psychic
Though not the fastest attacker, Mega Slowbro shines in PvP thanks to its incredible durability. It acts as a sturdy wall that can take numerous hits, especially when using Confusion and Psychic. It absorbs damage well while applying steady pressure. If you value survivability, Mega Slowbro is a strong choice.
6. Shadow Kingler

- Type: Water
- Strengths: high glass-cannon DPS
- Weakness: Electric and Grass
- Best Moveset: Bubble and Crabhammer
Using a Shadow Pokemon is a high-risk, high-reward strategy. These Pokemon deal 20% more damage but lose 20% of their defense. However, bulk isn’t as necessary if you can defeat enemies before they strike.
Shadow Kingler is often referred to as the “nuke” of Water-types. With Bubble and Crabhammer, it produces some of the highest Water-type DPS in the game. That said, its low durability means it’s best suited for raids where you can quickly rotate it out. If you’re after raw power, Shadow Kingler delivers.
7. Shadow Feraligatr

- Type: Water
- Strengths: Affordable and powerful, especially with Hydro Cannon
- Weakness: Electric and Grass
- Best Moveset: Water Gun and Hydro Cannon
Although not a legendary or a Mega, but Shadow Feraligatr holds its own with Water Gun and Hydro Cannon. The shadow boost gives it the damage it needs to keep up with top-tier attackers, and it’s more accessible than rarer Pokemon. It’s a solid pick for mid-level trainers aiming for strong Water-type performance.
8. Shadow Samurott

- Type: Water
- Strengths: Great moveset and balance, under-the-radar PvE performer
- Weakness: Electric and Grass
- Best Moveset: Fury Cutter and Hydro Cannon
This is a surprising underdog. With Fury Cutter for quick energy gain and Hydro Cannon for heavy hits, Shadow Feraligatr offers a good mix of speed and power. It may not be as flashy as others on this list, but it performs well in both PvE and limited PvP formats. If you have a strong one, don’t overlook it.
