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.

Key Stone accessories

A Key Stone can be inserted in various objects so that it can be kept on the owner's person. Many characters use different objects to hold their Key Stones.

Player character accessories

In Pokémon X and Y, the player characters hold their Key Stones in a Mega Ring (Japanese: メガリング Mega Ring), a large black bracelet that Calem and Serena wear on their left wrist. The player characters in Pokémon Omega Ruby and Alpha Sapphire have a Mega Bracelet (Japanese: メガバングル Mega Bangle), a large white bracelet that Brendan and May wear on their left wrist.

In Pokémon X and Y, possession of one Mega Ring is offered to the player and each of his or her friends, who have to pick the most deserving out of their group. The selection is quickly whittled down to two people: the player and Serena or Calem (depending on the gender of the player). Upon defeating their rival, the player must obtain the Rumble Badge at the Shalour Gym and then go to the top of the Tower of Mastery to receive the ring from Korrina.

After the player has beaten their rival in Kiloude City, Professor Sycamore will upgrade their Mega Ring at the Anistar Sundial by having the player touch the sundial. Once upgraded, the player can then find hidden Mega Stones around Kalos from 8:00 PM to 9:00 PM.

Non-player character accessories

Many non-player characters use different items to carry their Key Stones than the player characters do.

  • Lysandre's Mega Ring (Japanese: メガリング Mega Ring) takes the form of a black ring that he wears on the middle finger of his left hand.
  • Korrina uses a Mega Glove (Japanese: メガグローブ Mega Glove), which is a white glove she wears on her left hand.
  • Diantha uses a Mega Charm (Japanese: メガチャーム Mega Charm), which is the golden necklace she wears on her neck.
  • Steven Stone wears a (Japanese: メガラペルピン Mega Lapel Pin), which is a pin he wears on his shirt.
