Charizardite X and Key Stone in Pokémon Origins
A map depicting the locations of Mega Stones in Kalos
A Mega Stone (Japanese: メガストーン Mega Stone) is a type of held item introduced in Pokémon X and Y that allows Pokémon to Mega Evolve. According to Professor Sycamore, Mega Stones are the results of Evolution stones being irradiated by the power of the Legendary Pokémon XerneasX or YveltalY.
List of Mega Stones
In the core series games
During a battle, a Trainer can use their Key Stone (held in the Mega RingXY, Mega BraceletORAS, Z-RingSM, or Z-Power RingUSUM for the player character) to Mega Evolve a Pokémon that holds its corresponding Mega Stone before it attacks. Pokémon only remain Mega Evolved during battles and Pokémon Contest Spectaculars, and will revert to their original state once the battle has ended or if they faint. Every Pokémon that can undergo Mega Evolution has a corresponding Mega Stone that is named after it, except for Rayquaza, which instead needs to know the move Dragon Ascent to Mega Evolve. Some Pokémon have multiple different Mega Stones for their species.
Mega Stones cannot be transferred to or from the correct holder during battle: Thief and Covet do not take the Mega Stone, Knock Off does not remove the Mega Stone or cause extra damage, Trick and Switcheroo fail, Fling and Bestow fail, and Symbiosis does not activate. Embargo and Magic Room also cannot prevent the use of Mega Stones to Mega Evolve Pokémon. Mega Stones are not consumed upon use, but only one Pokémon can Mega Evolve per battle.
In Let's Go, Pikachu! and Let's Go, Eevee!, due to held items not being a mechanic, a Pokémon can Mega Evolve simply if the Trainer has a Key Stone and a compatible Mega Stone in their Bag. If a Pokémon has multiple Mega Evolutions (as it is with Charizard and Mewtwo), and the Trainer has both Mega Stones, then options to Mega Evolve into either can be selected from the battle screen.
In Pokémon X and Y, all Mega Stones not directly given or sold to the player can only be found between 8 and 8:59 p.m. after Professor Sycamore has upgraded the player's Mega Ring to detect them. These Mega Stones do not appear as item balls in the overworld; rather, they appear as sparkles on the ground.
In Pokémon Omega Ruby and Alpha Sapphire, Mega Stones on the ground appear as sparkles, like in Pokémon X and Y. Many Mega Stones that can be found in locations the player can already access will not appear until the player defeats or captures Primal GroudonOR/Primal KyogreAS. Some can only be obtained by meeting certain requirements, such as clearing all the Master Ranks in the Pokémon Contest Spectaculars and then defeating Lisia in one of the Master Rank Contests in order to receive the Lucarionite from Chaz or receiving the Garchompite from Aarune after achieving Platinum Rank in the Super-Secret Base by collecting 1,000 Flags.
The Mega Stone for Blaziken, the Blazikenite, cannot be found through normal gameplay in Pokémon X and Y. However, it can be obtained via special distributions and trading. The Mega Stone for Diancie, the Diancite, also cannot be obtained through normal gameplay in Pokémon Omega Ruby and Alpha Sapphire; instead, the stone can be obtained by having a Diancie in the party and activating an in-game event that results in the player being given a Diancite.
Pokémon holding Mega Stones introduced in Pokémon Omega Ruby and Alpha Sapphire (except Latiasite and Latiosite) cannot be traded to Pokémon X and Y.
In Pokémon Sun and Moon, only Mega Stones for Pokémon in the Alola Pokédex and for the fully-evolved Kanto starters are available through normal gameplay. Dexio gives the player the Alakazite and a Key Stone after defeating him on Ancient Poni Path after becoming Champion. Most Mega Stones can be purchased at the Battle Tree for 64 Battle Points. Red will give the player all Mega Stones associated with the starter Pokémon of the Kanto region after being defeated in a Single Challenge at the Battle Tree. The remaining Mega Stones have been distributed as event items; by participating in Pokémon Global Link online competitions or with universal codes provided on the official Pokémon website. Currently, all Mega Stone codes have expired; thus, the only current way to obtain these Mega Stones in Pokémon Sun and Moon is to trade them from Pokémon Ultra Sun and Ultra Moon.
In Pokémon Ultra Sun and Ultra Moon, all Mega Stones are available for purchase at the Battle Tree, except for Diancite, which is given to the player at Olivia's jewelry store in Konikoni City for showing a Collector a Diancie, and the Kanto Starter Mega Stones, which are received from Red or Blue at the Battle Tree. Dexio also gives the player Alakazite in these games, but he is found at the entrance to Poni Meadow in Poni Plains.
In Let's Go, Pikachu! and Let's Go, Eevee!, the player receives the Kanto starter Mega Stones along with a Key Stone from Blue at his grandfather's laboratory after obtaining seven Badges. Mewtwo's Mega Stones can be obtained from Green in Cerulean Cave after defeating her. The remaining Kanto Pokémon Mega Stones can be purchased from a Poké Maniac at Indigo Plateau after becoming Champion for 30,000 each.
Universal codes for event-exclusive Mega Stones
These codes were usable in all regions of Pokémon Sun and Moon, but expired at 8:59 JST on November 1, 2017.
In the anime
In the main series
In the XY series, Pokémon wear Mega Stones using equipment similar to that which their Trainers use to hold their Key Stones. The equipment disappears while the Pokémon is in its Mega Evolved state. In the Sun & Moon series, Mega Stones appear to be merged with the body of their holders and only appear whenever Mega Evolution is triggered.
Mega Stones were first mentioned in Lumiose City Pursuit!, where Professor Sycamore told Ash that a "special stone" is required to trigger Mega Evolution, referring to Mega Stones.
Mega Stones made their physical debut in Mega Evolution Special I. The Mega Stones seen were Alain's Charizardite X, Astrid's Absolite, Remo's Garchompite, Siebold's Blastoisinite, and a Gyaradosite found by Alain from a set of ancient ruins. In addition, a Lucarionite was seen in a painting featuring the first-ever Mega Evolution, which was shown to Alain by Professor Sycamore in a flashback. Astrid's Absolite made a brief reappearance during the opening credits of Diancie and the Cocoon of Destruction.
Diantha's Gardevoir's Gardevoirite debuted in The Bonds of Evolution!. The Embrace Pokémon was shown carrying its Mega Stone in a necklace around its neck.
A Lucarionite appeared in The Cave of Trials!, where it was found by Korrina in a cave near Geosenge Town. After battling a Blaziken guarding the Lucarionite—which was afterward revealed to belong to Korrina's grandfather, Gurkinn—Korrina obtained the Mega Stone and used it to Mega Evolve her Lucario. The uncut Lucarionite was later set in an armband by McGinty, allowing Lucario to wear the Mega Stone.
Another Lucarionite appeared in The Aura Storm!, under the ownership of Gurkinn. Much like Korrina's Lucario, Gurkinn's Lucario also wears its Lucarionite in an armband on its left wrist.
A Mawilite appeared in The Bonds of Mega Evolution!, worn by Mabel's Mawile in a piece of jewelry placed at the foot of its head jaws.
A Lucarionite appeared in a story told by Gurkinn in Origins of Mega Evolution!, depicting the first known Mega Evolution.
Steven's Shiny Metagross's Metagrossite appeared in Mega Evolution Special II, wearing it as a large bracelet on its right foreleg. An Ampharosite was also seen in a flashback in the same episode, having been found by Lysandre before Alain could get his hands on it.
Another Garchompite, belonging to Professor Sycamore and his Garchomp, appeared in Garchomp's Mega Bond!. Garchomp wears her Mega Stone as a choker around her neck.
Several different Mega Stones appeared in Mega Evolution Special IV. The Mega Stones seen included a Venusaurite attached to the tree on a Venusaur's back; an Alakazite tied onto one of Alakazam's spoons; and Malva's Houndoominite, which is attached to a collar her Houndoom wears around its neck.
An Audinite appeared in A Giga Battle with Mega Results!, where a Nurse Joy with an Audino had found one. She later used it and Professor Sycamore's Key Stone to Mega Evolve Audino.
An Abomasite appeared in A Real Icebreaker!, worn by Wulfric's Abomasnow. The Frost Tree Pokémon wears its Mega Stone on its chest, revealing it only when it is about to Mega Evolve.
A Charizardite Y appeared in A League of His Own!, worn by Trevor's Charizard in a ring around its tail.
A Sceptilite appeared in Valuable Experience for All!, worn by Sawyer's Sceptile on a bandanna that is tied around its neck.
In Volcanion and the Mechanical Marvel, Kimia's Shiny Gardevoir has a Gardevoirite in a necklace around its neck, which looks exactly like the necklace that Diantha's Gardevoir has.
A Gyaradosite appeared in Coming Apart at the Dreams!, worn by Lysandre's Shiny Gyarados around its neck in a holder similar to the one Alain's Charizard keeps its Charizardite X in. It is unknown whether this is the same Gyaradosite that Alain found in Mega Evolution Special I, or a different one.
A Steelixite worn by Brock's Steelix and a Gyaradosite worn by Misty's Gyarados appeared in When Regions Collide!.
An Aggronite appeared in The Prism Between Light and Darkness!, under the ownership of Team Rocket Elite Officer Gozu.
A Kangaskhanite appeared in Battling Besties!, under the ownership of Ilima.
In Pokémon Origins
Charizardite X (left) and a Key Stone (right) in Pokémon Origins
In File 2: Cubone, Mr. Fuji gave Red a Mega Stone and a Key Stone, although he did not tell Red what they truly were, merely saying that he would find out soon enough. In File 4: Charizard, during Red's battle against Mewtwo, one of the stones was revealed to be a Charizardite X that came from Kalos. Together, it and the Key Stone triggered Red's Charizard's Mega Evolution, allowing it to Mega Evolve into Mega Charizard X and weaken Mewtwo enough to be caught by Red.
In the manga
In the Pokémon - The Legend of the Dragon King manga
In Pokémon - The Legend of the Dragon King, which is centered around Mega Evolution, several characters have Mega Stones. Akira owns both a Charizardite X and a Charizardite Y, Koji owns a Garchompite, and Taichi has an Ampharosite.
In the Pokémon Adventures manga
Due to Mega Evolution being a relatively unknown phenomenon, the Mega Stone concept gradually developed. Trevor was not aware of the Mega Stone that X's Kanga possessed, until They Have a Flare for a Li'l Kanga-Napping when he found it in Kanga's pouch. In What Does Charmander Do When It Dozes?, Trevor and X proved that Kanga's Mega Stone had no effect when taken out of Kanga's pouch and placed with X's Chespin. In Overthrowing a Tyrunt, Trevor and X became aware of different Mega Stones and their names when the Team Flare Grunt they were fighting mentioned the Kangaskanite and Manectite explicitly. Trevor and X combined their skills to defeat the grunt in battle and steal a list of Mega Stones that he had supposedly compiled.
- Korrina's Lucario possesses a Lucarionite, allowing it to Mega Evolve into Mega Lucario.
- Gurkinn's Heracross wears its Heracronite around its horn.
- Diantha's Gardevoir wears its Gardevoirite around its head.
- Lysandre's Gyarados possesses a Gyaradosite, which a Team Flare grunt successfully dispatched to Malva.
- X's Élec possesses a Manectite, which is kept in a patch of fur on his chest. Élec was motivated to seek its Mega Stone after witnessing Kanga and Li'l Kanga Mega Evolve during a battle in the Prism Tower.
- X's Garma possesses a Gengarite, which is kept in a patch of fur under its jaw.
- Tierno and Shauna found multiple Mega Stones while looking for a Pinsirite and Absolite for X's Rute and Y's Solsol. After some searching, they successfully found the correct Mega Stones and gave them to X and Y.
- X's Salamè possesses a Charizardite X, which he keeps on the tip of his tail, hidden inside of tail's flame. Blue's Charizard possesses a Charizardite Y, which is also kept hidden inside of the flame on the tip of his tail. Both Charizard combined in their respective Mega Evolutions to defeat Xerosic, who claimed that Team Flare found no proof that a Charizard Mega Evolves, let alone into two different forms.
- Blaine possesses both a Mewtwonite Y and Mewtwonite X, which he can use to Mega Evolve Mewtwo into either of its Mega Evolutions.
The Mega Stones appear or are mentioned in the following rounds:
- In Omega Alpha Adventure 1, Latios revealed that he and Latias have obtained their respective Mega Stones.
- In Omega Alpha Adventure 2, it was revealed that Steven had already found the Mega Stones for Blaziken, Swampert, and Sceptile for Sapphire, Ruby, and Emerald, respectively.

- In Omega Alpha Adventure 11, Red and Green were revealed to have respectively obtained the Venusaurite and Blastoisinite, sometime before following Maxie and Archie, who had obtained the Cameruptite and Sharpedonite, respectively. The two pairs of Trainers used the Mega Stones with their respective Pokémon to battle each other.
- In Omega Alpha Adventure 20, Giovanni was revealed to have obtained a Beedrillite, using it to Mega Evolve his Beedrill as part of his explanation that the meteoroid threatening to destroy the world may be housing a Pokémon inside of it. The Meteor Village elder later offered Sapphire a Gardevoirite and Galladite, commenting how matching her Gallade and Ruby's Gardevoir are. Ruby and Sapphire later used these Mega Stones to Mega Evolve Rara and Kirly during a brief battle against each other.
- In Omega Alpha Adventure 21, after destroying the Grand Meteor Delta, Ruby has Hoopa find a Diancite for Diancie to use in the Pokémon Contest Spectacular, allowing Ruby to Mega Evolve Diancie for his and Sapphire's performance.
The following is a gallery of Mega Stone artwork as seen on the Pokémon Global Link.
- The design of the Mega Stones appear to be based on a common pattern found in the glass marble called a toothpaste or catseye marble.
- The Aggronite and Houndoominite are only obtainable in Pokémon Y, despite Aron, Houndour, and their evolutions being exclusive to Pokémon X.
- Likewise, the Tyranitarite and Manectricite are only obtainable in Pokémon X, despite Larvitar, Electrike, and their evolutions being exclusive to Pokémon Y.
- Despite not being officially introduced until Pokémon Omega Ruby and Alpha Sapphire, the Latiosite and Latiasite exist in the coding of Pokémon X and Y, making them the only Mega Stones which first became available in Pokémon Omega Ruby and Alpha Sapphire that can be transferred to Pokémon X and Y.
