Mega Ring

The Mega Ring is a special ring that allows a fully evolved Pokémon holding a Mega Stone to evolve even further. This evolution is only temporary though, and can wear off in time.

Before you can use Mega-Evolution on PFQ, you have to unlock the Mega Ring. The Mega Ring can be unlocked by doing the following: <spoiler show="Show spoiler" hide="Hide spoiler">Evolve Pokémon a total of 200 times or more, then visit Professor Holly.</spoiler>

Trivia

• In the official Pokémon X/Y games, the player can obtain a Mega Ring and use it to Mega-Evolve Pokémon during battle, provided that said Pokémon is holding its required Mega Stone.
