Evolution stone

File:Evostones.jpg

A collection of evolutionary stones.

An evolutionary stone (Japanese: 進化の石) is a type of item with mysterious properties. It radiates energy that causes some Pokémon to evolve.

If a Pokémon's next stage requires the use of a stone, then it can be applied at any time, thus causing instant evolution.

However, once exposed to an evolutionary stone, most Pokémon can no longer learn any more moves by leveling up. There are exceptions to this rule, however, and certain moves are exclusive to the stone-evolved Pokémon.

Evolutionary stones can be found in many places, and are uncommonly found in the Underground of Sinnoh. The Celadon Department Store sells several kinds during Generation I and Generation III.

There are nine types of evolutionary stones.

After an altercation with Team Rocket, this large Moon Stone exploded, raining shards down on the Clefairy, who, exposed to its radiation, evolved into Clefable.

File:OvalStoneSprite.png Oval Stone

This stone was first introduced in Generation IV.

An Oval Stone can be found in the Lost Tower. More can be found underground and there is a good (50%) chance it can be held by a wild Happiny or Chansey. Unlike other stones, it is not used on the Pokémon to evolve it, but instead held by it. It can be selected to be used like the other stones, however, it has no effect on any Pokémon.

Evolves

• Happiny → Chansey (level up when held during the day)

File:Everstone.png Everstone

This stone was first introduced in Generation II.

An Everstone is unlike any of the other stones, as when a Pokémon holds it, they will not evolve for whatever reason. Furthermore, a Ditto or a female Pokémon that holds an Everstone has a 50% chance of passing its nature to its offspring when at the Pokémon daycare. These can also be found underground.

In the Pokémon Special manga

In the Red, Green & Blue chapter a Moon Stone is first mentioned by Professor Oak in Gyarados Splashes In! as a rock with a moon shape inscription that boost Pokémon's power immensely, in the next round, Raging Rhydon, Team Rocket search for one in Mt. Moon, however it is Red who finds it.

In the anime

Oddish's evolutionary line as demonstrated in the anime.

The first appearance of evolutionary stones in the anime was that of the Moon Stone in Clefairy and the Moon Stone. After a rather large Moon Stone was blown up, its pieces rained down and caused several of the Clefairy gathered around to evolve.

A second appearance in The Electric Shock Showdown introduced the Thunderstone, as well as the first opportunity for one of the main characters' Pokémon to evolve via stone. However, Ash's Pikachu refused the offer to evolve, knocking away the Thunderstone.

All of the evolutionary stones introduced in Generation I appeared in The Battling Eevee Brothers, where two of the Eevee brothers offered a Thunderstone and a Fire Stone to Ash and Brock so that they could evolve their Pikachu and Vulpix. Both Ash and Brock declined.

A Leaf Stone appeared in Make Room for Gloom.

Another Leaf Stone appeared at the very end of Pikachu's Rescue Adventure. With it, the Exeggcute that had been following Misty's Togepi around evolved into Exeggutor.

Ash wins a Sun Stone in the Bug-Catching Contest during The Bug Stops Here. He later uses it to evolve a Sunkern in Moving Pictures.

Both the Leaf Stone and Sun Stone appear in Whichever Way the Wind Blows! as a demonstration of the branch in Oddish's evolutionary line.

The Water Stone appears in Once in a Mawile and is used by Brock's Lombre accidentally to evolve into Ludicolo. This is the first time that a main character's Pokémon evolves via stone, although it is possible that James's Weepinbell was evolved by way of a Leaf Stone prior to The Breeding Center Secret.

Strangely, evolutionary stones do not seem to be required for evolution in the anime as they are in the games. Melvin's Exeggcute evolve without a Leaf Stone in March of the Exeggutor Squad, though this may just be an example of anime physics.

Trivia

• So far, only Generation I Pokémon can use the Fire Stone and Thunderstone, only Generation II Pokémon can use the Dusk Stone, and only Generation III Pokémon can use the Dawn Stone.

• The Moon Stone, Leaf Stone, and Water Stone are the only stones introduced in one generation that evolve Pokémon introduced in a later generation.

• Excluding Generation III Pokémon, only one Pokémon that evolves by each of the stones introduced before that generation is found in the Hoenn Dex.

• Of the original five evolutionary stones, the Thunderstone sees the least use, with only two Pokémon species that evolve using it.

• All evolutionary stones introduced after Generation I can only evolve two species.

• Of all Pokémon that evolve by evolutionary stone, only Eevee and Gloom can use multiple ones; together they can use any of the stones introduced before Generation IV except for the Moon Stone.

• Only four Pokémon that evolve by stone can evolve in another method: Poliwhirl, Eevee, Kirlia, and Snorunt.

• Pokémon that result from a Pokémon evolving via Leaf Stone, Dusk Stone, and Shiny Stone do not have types that differ from their pre-evolutionary forms.

• Only Template:Type2 Pokémon evolve using the Leaf Stone and Sun Stone, and both Pokémon that evolve using the Sun Stone evolve into pure Grass-types.

• The Oval Stone is the only evolutionary stone that must be held by the Pokémon, instead of used directly on it, to induce evolution. Thus, it works more like a Razor Claw or Razor Fang in functionality.

• Of all the Pokémon that evolve by evolutionary stone, only Happiny is able to evolve further.

• In National Dex order, five evolution families in a row that use an evolutionary stone appear: Nidoran♀, Nidoran♂, Clefairy, Vulpix, Jigglypuff.
