Key Stone

A Key Stone (Japanese: キーストーン Key Stone) is a stone that acts as a medium between a Pokémon Trainer and a Pokémon holding a Mega Stone in order to make them Mega Evolve. A Key Stone is typically embedded in a personal accessory. When the Key Stone is activated, the Pokémon's corresponding Mega Stone reacts to it, starting the process.
== Recessional of the Red Dragons ==
During the Red Dragon War on Mars, several Key Stones were made to trigger Mega Evolutions. Whether it'd be Lucario, Blaziken, Blastoise, Absol, Gyarados, etc. and Mary and her cousins had to press their own wristbands as they chant, "Mega...? EVOLVE!" triggering the process.
== The ReBoot Multiuniverse ==
Akari also had several Pokémon that could Mega Evolve thanks to her Key Stones; even a primal Rayquaza as her secret weapon.
