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 38th strongest of the 40 damaging special moves that appear in this format.

Who carrys it

19 of the 282 Pokémon measured on the Regulation M-B ladder carry Weather Ball. The one that matters most is Mega Charizard Y, which is on 30.6% of teams and carrys it on 92.6% 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, Helping Hand, Quick Attack 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, Milotic, Ninetales-Alola, Vivillon, Dragonite 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 0.50 of the six slots on an average team, which makes it the 6th most-brought of the 126 moves this format runs. 57% 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 Fire (4), Grass (4) and Ice (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.
