Rock (type)

The **Rock type** (Japanese: **いわタイプ** *Rock type*) is one of the eighteen types. Prior to changes in Generation IV, all damaging Rock-type moves were physical, but they may now also be special depending on the attack.

## Battle properties

### Generation II onward

Rock-type Pokémon are immune to damage from the sandstorm weather condition.

Starting in Generation IV, Rock-type Pokémon have their Special Defense boosted by 50% during a sandstorm.

## Characteristics

### Defense

Tied with Grass, Rock types have the most weaknesses of any type, with five. Additionally, double weaknesses among Rock types are very common.

Since Generation IV, the Special Defense of a Rock-type Pokémon is increased by 50% during a sandstorm, in addition to being immune to the damage caused by it.

Rock-type Pokémon, on average, have the lowest Speed of all Pokémon and of fully evolved Pokémon.

### Offense

In particular, Rock pairs well with Ground, since very few Pokémon naturally resist this combination. Most Rock-types can learn Earthquake to this end. The biggest drawback of Rock-type moves is the large percentage of moves which have less than 100% accuracy.

### Contest properties

In Contests, Rock-type moves are typically Tough moves.

## Pokémon

As of Generation AN-V, there are 17 Rock-type Pokémon or 5.57% of all Pokémon, including those that are Rock-type in at least one of their forms, such as a regional form, except through abilities like Multitype. This makes it the 18th most common type, tying with the Dragon type.

## Abilities

### Interacting with the Rock type

A Pokémon with Color Change, Protean, Imposter, RKS System, or Multitype will become a Rock-type Pokémon if (respectively) it is hit with a Rock-type move, uses a Rock-type move, is sent out against a Rock-type opponent, is holding a Rock Memory, or is holding a Stone Plate or Rockium Z.

### Exclusive Abilities

Currently, no Abilities are exclusive to Rock types. This does not include signature Abilities.

## Trivia

* Generation III introduced the most Rock-type Pokémon of any Generation, with 12. Generation VII and Generation VIII introduced the fewest Rock-type Pokémon, with five each.
* Generation IV introduced the most Rock-type moves of any Generation, with six, and Generation VI introduced the fewest Rock-type moves, with only one.
* In the first season of the anime and during much of Generation I, the Rock type was often wrongly assumed to be unaffected by Electric-type attacks. This was likely due to the fact that at the time, most Rock-type Pokémon (namely the Geodude and Rhyhorn evolution lines, and Onix) were part Ground-type and thus immune to Electric-type moves. However, the only non-Ground Rock-type Pokémon around at the time (the then five Fossil Pokémon) were actually weak to them.
* In the anime on multiple occasions, like in *Showdown in Pewter City*, *Sick Daze* and *Right On, Rhydon!*, Ground and Rock-type Pokémon are said to have strong aversion to water and generally being wet. Rhydon is often presented as an exception to this rule due to its ability to use the move Surf.
* The Rock type is tied with the Grass type for the largest number of weaknesses when unpaired, with five. However, a combination of the two types (Rock/Grass) would only have four weaknesses.
	+ Rock moves are super effective against four of the five types Grass is weak to, with Poison being the exception.
* Most Fossil Pokémon are either part or solely Rock-type. This is most likely due to the placement of real fossils in rock formations, as well as the process by which fossils are created.
* Johto's Olivine Gym was a Rock type Gym before the Steel type was discovered.
* The Rock type has the fewest special moves of all types, with three.
* Despite being introduced in Generation I, there were no pure Rock-type Pokémon until Generation II, with only Sudowoodo.
