The Rock-type (いわタイプ, Iwa Taipu) is one of the eighteen types. Notable Trainers that specialize in Rock-type Pokémon are Brock, Flint and Forrest of Pewter City, Roxanne of Rustboro City and Roark of Oreburgh City. They are, notably, all the first Gym Leader encountered in their respective regions. Jasmine is also stated to have trained Rock types in the past. Prior to Generation Diamond, Pearl, and Platinum all Rock-type moves were physical or special based on the move itself rather than the type, all Rock-type moves were physical.
Rock is one of the best types offensively. Being resisted by only three of the seventeen types, two of which are hindered by their own bad defenses and relative scarcity helps it a lot, and the fact that only four Pokémon out of 649 have a double resistance to Rock keeps its moves relatively effective. Double weaknesses to Rock are relatively common, mostly due to the many Bug types having Flying as a secondary type, while the typically high-powered Ice- and Fire types also do not fare well. As Pokémon of the three types that resist Rock typically can master Rock-type moves, this proves a quite versatile combination.
The Rock type is rather risky defensively. Despite having an overall high Defense on average, and whilst it is defensive against the very common Normal-type moves, its weaknesses to Ground- and Fighting moves, typically physical in nature and rather commonly used, take it down a notch. The fact that its Special Defense is mediocre at best combined with its weakness to the common Grass- and Water moves greatly decrease its ability to defend.
Double weaknesses among Rock types are very common. Rock/Steel Pokémon are doubly weak to Ground and Fighting, two common powerful types. Rock/Water Pokémon and Rock/Ground Pokémon are doubly weak to Grass and the latter is also doubly weak to the common Water (along with an extra weakness to the powerful Ice.) The low Speed that many Rock types have causes even further problems. Their resistance to Fire can now be made useless as many Fire types' movesets have been expanded in Generation Diamond, Pearl, and Platinum to include Grass attacks (most notably Solar Beam). Furthermore, tied with Grass, Rock types have the most weaknesses, with five.
However, resistances to Normal, Flying and Fire help the Rock type to hold its own if it needs to. Moreover, in a Sandstorm the Special Defense is increased by 50%. Furthermore, Sandstorms are very common in many tiers, thanks to Sand Stream automatically casting a permanent Sandstorm.
As of Generation Unova, there are 47 Rock-type Pokémon or 7.24% of all Pokémon, making it the tenth most common type.
Pure Rock-type PokémonEdit
Half Rock-type PokémonEdit
Primary Rock-type PokémonEdit
Secondary Rock-type PokémonEdit
- Generation Hoeen introduced the most Rock-type Pokémon of any Generation, with 12, and Generations Johto and IV introduced the least Rock-type Pokémon, with seven.
- Generation Diamond, Pearl, and Platinum introduced the most Rock-type moves of any Generation, with six, and Generations Kanto, Hoeen, and Unova introduced the least Rock-type moves, all with two.
- If there were a Pokémon of all 17 types, it would be weak to only Rock-type moves, due to the fact that there are more Pokémon types weak to it than Pokémon types that resist it, and that no types are immune to it.
- In the first season of the anime and during much of Generation Kanto, the Rock type was often wrongly assumed to be unaffected by Electric attacks. This was likely due to the fact that at the time, most Rock-type Pokémon were part Ground-type, and thus immune to Electric-type moves. However, the only non-Ground Rock-type Pokémon (the then five Fossil Pokémon) were actually weak to them.
- The Rock type is tied with the Grass type for the largest number of weaknesses when unpaired, with five: Grass, Water, Ground, Fighting, and Steel.
- Seven of the fifteen Rock-type moves (just under half) have the word 'rock' in their names.
- Every known Fossil Pokémon is 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.
- Every known Gym that specializes in the Rock type has been the first Gym of its region.
- Similarly, each of the Leaders of these Gyms have used Geodude as at least one of their Pokémon.
- Black, White, Black 2, and White 2 are the only main series games that do not have a Rock-type Gym.
- Johto's Olivine Gym was a Rock type Gym before the Steel type was discovered.
- In Generation Kanto there were only two Rock-type moves, which made it the type with the second fewest moves. Only the Dragon type had fewer moves, with only one move.
- Ancient Power and Power Gem are the only special Rock-type moves.
- Generation Kanto is the only generation not to have introduced at least one pure Rock-type Pokémon.
