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. It allows Pokémon to Mega Evolve. According to Professor Sycamore, Mega Stones are the results of Evolutionary stones being irradiated by the power of the Legendary Pokémon Xerneas^X or Yveltal^Y. In Pokémon Omega Ruby and Alpha Sapphire, it has been revealed that Mega Stones are also periodically created from meteorites that fall down from the sky in a form of green light.

Mechanics

During battle, the player can use their Key Stone-activating item, the Mega Ring^XY/Mega Bracelet^ORAS to Mega Evolve a Pokémon before it attacks if it is holding the correct Mega Stone. Mega Stones only affect Pokémon during battles, and Pokémon will revert to their basic form once the battle has ended or upon fainting. All Pokémon that can undergo Mega Evolution have an equivalent Mega Stone that is named after them, except for Rayquaza, which instead needs to know the move Dragon Ascent to Mega Evolve.

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, 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.

Availability

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 Groudon^OR/Primal Kyogre^AS. Some can only being obtained through 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 stone for Blaziken, the Blazikenite, cannot be found through normal gameplay in X and Y. However, it can be obtained via special distributions and trading. The stone for Diancie, the Diancite, also cannot be obtained through normal gameplay in Omega Ruby and Alpha Sapphire. Instead, the stone can be obtained by transferring or trading Diancie from Pokémon X and Y to Pokémon Omega Ruby and Alpha Sapphire, activating an event in Omega Ruby and Alpha Sapphire that will allow the Diancite to be obtained.

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 the anime

Siebold's Blastoise wearing its Blastoisinite

In the main series

In the anime, 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.

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 first physical appearance in Mega Evolution Special I. The seen Mega Stones were Alain's Charizardite X, Astrid's Absolite, Remo's Garchompite, Siebold's Blastoisinite, and an unknown orange Mega Stone found by Alain from ancient ruins. In addition, a Lucarionite was seen in a painting shown to Alain by Professor Sycamore in a flashback, featuring the first ever Mega Evolution. Astrid's Absolite made a brief reappearance during the opening credits of Diancie and the Cocoon of Destruction.

Diantha's Gardevoir's Gardevoirite appeared in The Bonds of Evolution!. The Embrace Pokémon was shown carrying its Mega Stone in a necklace around its neck.

A Lucarionite made an appearance 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 afterwards 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 seen Mega Stones include 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 her Houndoom wears on a collar 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 XY122, worn by Wulfric's Abomasnow. The Frost Tree Pokémon wears its Mega Stone on its chest, revealing it only when it's about to Mega Evolve.
