This Pokemon does not take recoil damage, except Struggle. Does not affect Life Orb damage or crash damage.
Smogon rates it 3 on their competitive scale, where 5 is format-defining and 0 is actively unhelpful.
5 of the 282 Pokémon measured on the Regulation M-B ladder run Rock Head. The one that matters most is Aerodactyl, which is on 3.2% of teams and runs it on 3.2% of its sets. The full list is above, ordered by how much of the format each one is.
5 of the Pokémon legal in Regulation M-B have Rock Head in their ability list, and 5 of those are played often enough to measure. An ability is not a choice the way a move or an item is — most Pokémon that have it have no alternative worth taking — so the gap here is about what sees play, not about what is preferred.
Across the ladder, Rock Head accounts for an expected 0.01 of the six slots on an average team, which makes it the 19th most-brought of the 19 abilities this format runs. 9% of that comes from Aerodactyl alone, so it is spread across the field rather than propped up by one Pokémon. Its users are mostly Rock (4) and Steel (2).
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.
