Unlock and activate Mega Evolution

Mega Ring: AZ lends you Lucario and provides the Mega Ring during Main Mission 9, Chase That Mysterious Pokémon. Mission details →
Starter stone: Main Mission 10, The Secrets of Mega Evolution, continues the tutorial and provides the Mega Stone for your starter. Mission details →
Prepare: Give the matching Mega Stone to an eligible Pokémon. Your Mega Ring contains the Key Stone; the Pokémon holds its stone.
Transform: Send out the Pokémon, fill the Mega Power gauge, then press the right stick with the default controls.

Charge: Battling builds Mega Power. Collect Mega Power orbs to add energy; Rogue Mega opponents drop orbs when attacked.
Plus Moves: A mastered Plus Move uses part of the same gauge outside Mega Evolution. During Mega Evolution, moves automatically use their Plus versions. Related reference →
Duration: Mega Power drains while the Mega-Evolved Pokémon is active. It reverts when the gauge empties. Collecting orbs can extend the transformation.
Switching: Recalling a Mega-Evolved Pokémon pauses its Mega Power use. Only one of your Pokémon can be Mega-Evolved at a time; recalling it does not free that slot.
Use again: After the transformation ends, recharge the gauge to Mega Evolve again.

Types and stats: Mega Evolution is temporary. It changes the Pokémon’s base stats and can change its types. Compare each form below; the six stat changes are shown against its eligible base form.
Rayquaza: Rayquaza needs to know Dragon Ascent instead of holding a Mega Stone. Pokémon profile →
Zygarde: Zygarde must first reach Complete Forme and hold Zygardite. In battle, its 10% or 50% Forme changes to Complete Forme at half HP or below. Core Enforcer becomes Nihil Light during Mega Evolution. Pokémon profile →
Floette: Floettite works with Eternal Flower Floette, rather than the ordinary flower-color forms. Pokémon profile →
Shared stones: Male and female Meowstic share Meowsticite. Both Magearna colors share Magearnite, and all three Tatsugiri forms share Tatsugirinite.

Z Mega Evolution: Z Mega Evolutions start moves sooner after an order but spend Mega Power faster. Their shorter attacking window differs from an ordinary Mega Evolution. Related reference →
Availability: Check the matching stone’s item page for acquisition, event restrictions and progression. Ranked rewards and Mystery Gifts have their own availability periods.
Multiplayer: Transforming provides a brief moment of invincibility in Ranked and Private Battles.
