All Mega Evolutions

Updated on 2026-09-02

Mega Evolution arrived in Generation VI (X/Y) as a temporary transformation that lasts only for the battle. To use it, the trainer needs a specific Mega Stone held by the Pokémon plus a key item (the Mega Ring). Once per battle, the Pokémon Mega Evolves at the start of the turn and gains new stats, sometimes a new type, and almost always a new Ability.

Why it matters

• Immediate power jump: base stat total rises about 100 points, usually concentrated in Attack/Sp. Atk and Speed.
• Only one per team: you can carry several Mega Stones, but only one Pokémon Mega Evolves per battle, which makes the choice strategic.
• Persists on switch: when recalled and sent back out, the Pokémon returns Mega Evolved — the form lasts as long as it stays on the field that battle.

Standout examples

• Mega Charizard X: becomes Fire/Dragon with Tough Claws and enormous physical Attack.
• Mega Charizard Y: stays Fire/Flying, gains Drought (automatic sun) and devastating Sp. Atk.
• Mega Kangaskhan: Parental Bond makes every hit land twice — banned from standard competitive play.
• Mega Rayquaza: needs no Mega Stone, just the move Dragon Ascent; one of the strongest creatures ever released.
• Mega Gengar: Shadow Tag traps the opponent, preventing the switch.
• Mega Lucario, Mega Metagross, Mega Salamence, Mega Garchomp: four offensive heavyweights from Gens 3 and 4.

Current status

Mega Evolution was left out of Sword/Shield, Scarlet/Violet and most post-Gen 7 games — replaced first by Z-Moves, then by Dynamax and Terastallization. It remains playable in Pokémon GO and in simulator formats. Every Pokémon with Mega access shows the form on its species page here on NoxDex.
