What it does

Power doubles if a weather condition other than Delta Stream is active, and this move's type changes to match. Ice type during Snow, Water type during Primordial Sea or Rain Dance, Rock type during Sandstorm, and Fire type during Desolate Land or Sunny Day. If the user is holding Utility Umbrella and uses Weather Ball during Primordial Sea, Rain Dance, Desolate Land, or Sunny Day, this move remains Normal type and does not double in power.

At 50 base power it is the 37th strongest of the 39 damaging special moves that appear in this format.

Who carrys it

19 of the 277 Pokémon measured on the Regulation M-B ladder carry Weather Ball. The one that matters most is Mega Charizard Y, which is on 26.5% of teams and carrys it on 91.5% of its sets. The full list is above, ordered by how much of the format each one is.

What it hits

As a Normal move it is super effective against nothing, resisted by Rock and Steel, and does nothing at all to Ghost. 16 other Normal moves appear in this format: Protect, Fake Out, Encore, Hyper Voice, Swords Dance, Helping Hand and others.

Who could and does not

45 Pokémon legal in this regulation can learn Weather Ball at all, against the 19 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 Sylveon, Ninetales-Alola, Milotic, Dragonite, Vivillon and Primarina — each of them measured on the ladder, each of them leaving this move on the shelf.

How concentrated it is

Across the ladder, Weather Ball accounts for an expected 0.40 of the six slots on an average team, which makes it the 10th most-brought of the 121 moves this format runs. 61% of that comes from Mega Charizard Y alone, so it is really one Pokémon’s move rather than the format’s. Its carriers are mostly Grass (5), Water (5) and Fire (4).

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 Mega Charizard Y seated — Mega Charizard Y brings Weather Ball to more teams than any of the other 18 Pokémon that carry it.
