What it does

No additional effect.

At 110 base power it is the 9th strongest of the 39 damaging special moves that appear in this format.

Who carrys it

8 of the 277 Pokémon measured on the Regulation M-B ladder carry Hydro Pump. The one that matters most is Rotom-Wash, which is on 3.5% of teams and carrys it on 93.8% of its sets. The full list is above, ordered by how much of the format each one is.

What it hits

As a Water move it is super effective against Fire, Ground and Rock, resisted by Dragon, Grass and Water. 9 other Water moves appear in this format: Wave Crash, Aqua Jet, Flip Turn, Life Dew, Scald, Muddy Water and others.

Who could and does not

47 Pokémon legal in this regulation can learn Hydro Pump at all, against the 8 that actually bring it. The gap is the interesting number: it is the set of Pokémon that have the option and decline it. The most-played of those are Basculegion, Pelipper, Milotic, Toxapex, Politoed and Dragonite — each of them measured on the ladder, each of them leaving this move on the shelf.

How concentrated it is

Across the ladder, Hydro Pump accounts for an expected 0.03 of the six slots on an average team, which makes it the 85th most-brought of the 121 moves this format runs. 93% of that comes from Rotom-Wash alone, so it is really one Pokémon’s move rather than the format’s. Its carriers are mostly Water (8) and Psychic (2).

Where these numbers come from

Usage is Smogon's published statistics for the Regulation M-B VGC ladder, and the description is the one shipped in the Pokémon Showdown data set. Both are regenerated on every build rather than written by hand, so this page follows the format instead of trailing it. Take any of it to the team builder or the damage calculator.

Where this goes next

Build

Open the builder with Rotom-Wash seated — Rotom-Wash brings Hydro Pump to more teams than any of the other 7 Pokémon that carry it.
