Evolution stone

If you were looking for the item whose Japanese name translates to Evolution Stone, see Eviolite.

Gloom's branched evolution family as demonstrated in the anime: both of Gloom's potential evolutions require an Evolution stone.

An Evolution stone (Japanese: 進化の石 Evolution stone) is a type of Evolution item introduced in Generation I. They can be used to evolve certain Pokémon to their final evolutionary stage. As of Generation VIII, there are 10 available evolution stones, which are used by 40 Pokémon species.

These items have been referred to as Evolution stones since Pokémon X and Y (in the games) and Pokémon the Series: Black & White (in the anime). Previous generations of the games and anime have used different names:

In the core series games

Using an Evolution stone on an appropriate Pokémon causes it to evolve instantly, consuming the Evolution stone. This process cannot be stopped by pressing the B button.

Many Pokémon that result from a stone-based evolution can no longer learn new moves by leveling up, unlike their pre-evolved form. Starting in Generation VIII, however, the Pokémon that this apply to may instead learn the moves their pre-evolution could learn at the Move Reminder, gaining access to all of the previous form's level up moves regardless of level.


While individual Evolution stones can often be found in a variety of locations, multiple different Evolution stones can often be acquired in a single location.

In spin-off games

Pokémon Conquest

In Pokémon Conquest, Evolution stones are required to evolve certain Pokémon. They can be purchased from the traveling merchant. Keiji gives the player a Fire Stone, a Water Stone, and a Thunder Stone during the main story.

Pokémon GO

In Pokémon GO, there are three Evolution stones: the Sun Stone, Sinnoh Stone, and Unova Stone. The latter two stones are unique to Pokémon GO. Starting at Trainer level 10, Players can obtain these stones, along with other Evolution items, as rare rewards from opening gifts and spinning PokéStops or Gyms. Players can also receive Sun Stones as the guaranteed Evolution item from spinning PokéStops or Gyms seven days in a row. Evolution stones are also available as rewards from certain Field Research and Special Research tasks, and Sinnoh Stones and Unova Stones are potential rewards for Research Breakthroughs.

The Sun Stone is required to evolve the same Pokémon as in other media.

The Sinnoh Stone is used to evolve most Pokémon into their cross-generational evolutions that were introduced in Generation IV. The exceptions are the Pokémon that require special Lure Modules instead of Evolution Stones: Magneton and Nosepass (which require a Magnetic Lure Module to evolve), and Eevee (which requires a Mossy Lure Module to evolve into Leafeon or a Glacial Lure Module to evolve into Glaceon).

The Unova Stone is used to evolve Generation V Pokémon that evolve using any Evolution stone in other media, except a Sun Stone.

In the anime

A giant Moon Stone in the anime

The first Evolution stone to appear in the anime was Moon Stone in Clefairy and the Moon Stone. A giant Moon Stone appeared deep within Mt. Moon, being worshiped by a group of Clefairy who lived there. It was soon stolen by Team Rocket, and ultimately ended up being blown up; the shards from the shattered giant Moon Stone rained down on the Clefairy and caused some of them to evolve into Clefable. In this episode, the characters speculated that the Moon Stone was how various Pokémon—Clefairy in particular—arrived in the Pokémon world. Another giant Moon Stone was later seen in the same location in A Real Cleffa-Hanger.

In Electric Shock Showdown, Nurse Joy gives Ash a Thunder Stone so that he could evolve his Pikachu in order to defeat Lt. Surge's Raichu. Pikachu, however, refused the offer. Ash kept the Thunder Stone in case Pikachu ever wanted to evolve; however, in Pika and Goliath!, a similar scenario occurred and Pikachu still refused to evolve. Seeing his determination to not evolve, Team Rocket stole the stone, planning to sell it.

The remaining Generation I Evolution stones debuted in The Battling Eevee Brothers as part of a collection held by the Eevee brothers. Additionally, two of the Eevee brothers offered a Fire Stone and Thunder Stone to Brock and Ash to evolve their respective Vulpix and Pikachu, though both refused.

The Leaf Forest appeared in The March of the Exeggutor Squad, which was a reported hotbed of Leaf Stones. The radiation from these stones in the forest was so strong that it caused Melvin's Exeggcute to evolve.

A fake Leaf Stone, made by Team Rocket, appeared in Make Room for Gloom, where the discovery of its nature as a fake was central to the episode.

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

In The Grass Route, a set of Leaf Stones was offered as the prize for winning the Grass Tournament. Although Team Rocket tried to steal the stones, they were eventually won by Ephraim. He planned on using to evolve his parents' Pokémon.

Ash won a Sun Stone in the Bug-Catching Contest during The Bug Stops Here, later using it to evolve a wild Sunkern in Moving Pictures.

A set of Fire Stones played an important role in The Stolen Stones!, where Ramona and Keegan had been tasked with delivering them to be used as prizes for the competitors of a Fire-type Pokémon competition. During the delivery, Team Rocket stole the stones, requiring Ash and his friends to help retrieve them.

Both a Leaf Stone and a Sun Stone appeared in Whichever Way the Wind Blows during an explanation of the branch in Gloom's evolutionary family.

In Once in a Mawile, a Water Stone belonging to Samantha appeared, which Brock's Lombre used to evolve into Ludicolo. This is the first time that a main character's Pokémon evolves via Evolution stone onscreen, although it is likely that James's Weepinbell was evolved using a Leaf Stone prior to The Breeding Center Secret.

A Moon Stone appeared in a flashback in Delcatty Got Your Tongue?, evolving Dr. Abby's Skitty into a Delcatty.

Professor Oak gave a Water Stone to a wild Lombre in A Faux Oak Finish!.

A Dusk Stone was central to the plot of Try for the Family Stone!, where Rhyanna and Mitchell searched for one to evolve their respective Pokémon. They eventually found one, and decided to have a battle to settle which one of them would get to use it.

Ursula used a Fire Stone and a Water Stone to evolve her two Eevee in Last Call, First Round!, making them a Flareon and Vaporeon, for use in the Sinnoh Grand Festival.

Ash had to find a Thunder Stone as part of a scavenger hunt during the Wishing Bell Festival in Climbing the Tower of Success!. He came across a young man in possession of one who tried to toss it to him from a long distance. The Thunder Stone nearly came in contact with Pikachu but he jumped out of the way just in time leaving Ash to catch it.

Mystery on a Deserted Island! featured all Evolution stones available as of Generation V. Several Eevee were shown to evolve into Jolteon, Flareon and Vaporeon using the required stones.

A Thunder Stone appeared in To Catch a Pokémon Smuggler! as a part of Clemont's explanation of how Pokémon Evolution works, Pikachu's evolution into Raichu working as an example of stone-induced Evolution.

A full set of Evolution stones was seen on display in a stone shop in Geosenge Town in The Cave of Trials!. In addition, an unnamed Trainer used a Sun Stone purchased from the shop to evolve his Helioptile into Heliolisk. Clemont then revealed that he had also used a Sun Stone to evolve his own Helioptile into Heliolisk.

A Moon Stone appeared in a fantasy in A Dream Encounter!, where it was revealed that Lusamine had used one to evolve her Clefairy into a Clefable.

An Ice Stone was first seen in Not Caving Under Pressure!, where Sophocles's Charjabug found one while helping to fix up a cave inhabited by a group of Alolan Sandshrew, revealing that the cave was in fact an Ice Stone mine where Sandshrew gather to evolve. The leader of the Sandshrew pack, a giant Sandshrew, touched the stone and proceeded to evolve into an Alolan Sandslash. Later, after exiting the cave, Charjabug was revealed to have found another Ice Stone, which Sophocles gave to Lillie. She asked Snowy if it wanted to use the stone to evolve, but Snowy didn't feel ready for it yet, so Lillie decided to hold on to the stone in case Snowy ever changed its mind.

Multiple Thunder Stones appeared in Gotta Catch a What?!, where multiple wild Pikachu were digging them up in a valley in order to evolve. One was found by Goh's newly caught Pikachu, who gave it to her Trainer. Later, Goh used the Stone to evolve his Pikachu into Raichu in order to help defeat Team Rocket.

In That New Old Gang of Mine!, Professor Cerise's Yamper gave Goh a Leaf Stone he had found. Goh immediately used the stone to evolve his Exeggcute into Exeggutor.

In To Train, or Not to Train!, staff members of the Eevee Evolution Lab tried to use a Fire Stone and a Thunder Stone on an Eevee to evolve her, but both attempts failed.

Evolution stones do not seem to be required for evolution in the anime as they are in the games. James's second Weepinbell evolved without a Leaf Stone in Here's Lookin' at You, Elekid. In addition, Pokémon that evolve via proximity of Evolution stones apparently seem to control their evolutionary urges and physically touch the stone without evolving, as evidenced by Pikachu whacking away the Thunder Stone when refusing to evolve the first time, as well as a Clefairy holding onto a Moon Stone for prolonged periods of time before delivering it to the larger Moon Stone without evolving.

In the manga

The Electric Tale of Pikachu

Evolution stones in The Electric Tale of Pikachu

In Clefairy Tale, Ash, Professor Oak, and Bill witnessed a Clefairy evolution ceremony involving a large Moon Stone.

The focus of the chapter To Evolve or Not to Evolve, That Is the Question! was Evolution stones. Misty hoped to buy a Water Stone for her Poliwhirl in Stone Town, a town on Dream Island where all the Evolution stones in the Pokémon world come from. However, she couldn't afford one, remarking that an inexpensive one might make the evolution go bad.

Misty was later given a Water Stone by Mikey, who was being pressured to join the "Knights of the E Stone", a club which requires members to own a Pokémon evolved by an Evolution stone. By battling club members, Ash and Mikey proved to the club leaders that Pokémon which have evolved by Evolution stone are not necessarily superior to their unevolved counterparts.

Pokémon Adventures

Evolution stones in Pokémon Adventures


Red, Green & Blue chapter

A Moon Stone was first mentioned by Professor Oak in Gyarados Splashes In! as a rock with a crescent moon-shaped indentation that boosts a Pokémon's power immensely. In the next round, Team Rocket searched for one in Mt. Moon. However, it was Red who eventually found it. In The Winged Legends, Red used his Moon Stone to evolve Green's Clefairy into a Clefable in order to fight Thu-Fi-Zer during the Silph Co. showdown with Team Rocket.

In Buzz Off, Electabuzz!, Red's Poliwhirl was able to evolve into a Poliwrath with the help of a Water Stone when they were thrown into the water in Vermilion Harbor, although the cause of his evolution wasn't revealed until the Yellow chapter.

Yellow chapter

In The Kindest Tentacruel, the Pokémon Fan Club Chairman told Yellow about a legend of an underwater dome at the bottom of Vermilion Harbor, housing a set of Evolution stones which, unlike normal stones, did not disappear after making a Pokémon evolve, allowing them to be used repeatedly. The cause of Red's Poliwhirl's evolution had been one of these said stones, proving the legend to be true. Yellow was later led to the dome by a wild Tentacruel, finding a Leaf Stone in it, but the Fire, Thunder, and Water Stones were missing. Later, it was revealed that Giovanni had given them to Red so he could freely evolve and devolve his Eevee.

  • In the Generation I core series games, due to a a glitch, Pokémon that would normally require an Evolution stone to evolve may also evolve after leveling up in battle, if the player had sent out a specific Pokémon in the same battle it leveled up.
  • No Pokémon that has evolved from exposure to an Evolution stone is capable of evolving again.
  • Despite the fact that Oval Stone is sorted along with other Evolution stones in all core series games since its introduction, it is not an Evolution stone, as it can only cause evolution as a held item; it cannot be directly used on a Pokémon like the Evolution stones are.
    • This makes Oval Stone the only Evolution item with "Stone" in its English name which is not an Evolution stone.
  • The Leaf Stone is the only Evolution stone that cannot be sold to the ore maniac in Black and White. This was corrected in Black 2 and White 2.
  • All Pokémon that evolve with the Fire Stone and the Ice Stone are in the Field Egg Group.
  • The Dawn Stone is the only stone which can only evolve a Pokémon if it is a specific gender, with this requirement applying to both of the Pokémon it can evolve.
  • The Sun Stone and Moon Stone share their names with actual gemstones.
  • The Sinnoh Pokédex is the only regional Pokédex to not include any Pokémon compatible with the Sun Stone.
  • In Pokémon Platinum, due to the unavailability of the Murkrow and Misdreavus lines, the Dusk Stone cannot be used on any Pokémon without trading. This is the only case where an Evolution stone is available but not usable on any available Pokémon.
  • Gloom and Eevee are the only Pokémon compatible with more than one Evolution stone in the same form.
    • Vulpix as a species is compatible with two different Evolution stones, but each form is only compatible with a single stone.
