This guide covers everything you need to know about Mega Evolution, from how it works to the best Mega Pokémon for battles.

How Mega Evolution Works
Mega Evolution requires three things: a Pokémon that can Mega Evolve, the corresponding Mega Stone, and a Key Stone held by the trainer. During battle, you can Mega Evolve your Pokémon once per battle by selecting the Mega Evolve option before choosing a move.
Mega Evolution lasts for the duration of the battle. When the battle ends, the Pokémon reverts to its normal form. Mega Evolution provides a significant boost to base stats, and may also change the Pokémon's typing, ability, or both.
One important rule: you can only Mega Evolve one Pokémon per battle. This means you need to choose carefully which Pokémon to Mega Evolve, as it will be your most powerful asset for that battle.
Mega Stones List
There are 48 Mega Stones in total, each corresponding to a specific Pokémon. Here are some of the most important ones:
- Venusaurite: Mega Evolves Venusaur into Mega Venusaur (Grass/Poison)
- Charizardite X: Mega Evolves Charizard into Mega Charizard X (Fire/Dragon)
- Charizardite Y: Mega Evolves Charizard into Mega Charizard Y (Fire/Flying)
- Blastoisinite: Mega Evolves Blastoise into Mega Blastoise (Water)
- Mewtwonite X: Mega Evolves Mewtwo into Mega Mewtwo X (Psychic/Fighting)
- Mewtwonite Y: Mega Evolves Mewtwo into Mega Mewtwo Y (Psychic)
- Gengarite: Mega Evolves Gengar into Mega Gengar (Ghost/Poison)
- Lucarionite: Mega Evolves Lucario into Mega Lucario (Fighting/Steel)
- Garchompite: Mega Evolves Garchomp into Mega Garchomp (Dragon/Ground)
- Salamencite: Mega Evolves Salamence into Mega Salamence (Dragon/Flying)
Best Mega Pokémon
Not all Mega Evolutions are created equal. Here are the top 5 Mega Pokémon for competitive battles:
1. Mega Rayquaza (Dragon/Flying)
Mega Rayquaza is arguably the most powerful Pokémon in the game. It doesn't need a Mega Stone — it only needs to know the move Dragon Ascent. With 754 base stats and the Delta Stream ability (which eliminates Flying-type weaknesses), Mega Rayquaza is banned from even the Uber tier.
2. Mega Mewtwo Y (Psychic)
With 194 base Special Attack (the highest in the game) and 140 base Speed, Mega Mewtwo Y is the ultimate special sweeper. Its Insomnia ability also prevents sleep, making it immune to common status moves.
3. Mega Gengar (Ghost/Poison)
Mega Gengar's Shadow Tag ability prevents opponents from switching, trapping them in battle. This makes Mega Gengar one of the best trappers in the game, capable of eliminating specific threats.
4. Mega Lucario (Fighting/Steel)
Mega Lucario has 145 base Attack and 140 base Special Attack, making it a versatile mixed attacker. Its Adaptability ability boosts STAB moves from 1.5x to 2x, making its Aura Sphere and Close Combat incredibly powerful.
5. Mega Charizard Y (Fire/Flying)
Mega Charizard Y has 159 base Special Attack and the Drought ability, which summons harsh sunlight. This boosts Fire moves by 50% and allows Solar Beam to be used in one turn, making Mega Charizard Y a devastating special attacker.
Mega Evolution Strategy
When using Mega Evolution in battle, timing is everything. Here are some key strategies:
- Mega Evolve early: Mega Evolution happens before moves, so Mega Evolving on the first turn gives you the stat boost immediately.
- Consider the ability: Some Mega abilities change the battle field (Drought, Drizzle) or trap opponents (Shadow Tag). Use these to your advantage.
- Type changes: Mega Charizard X changes from Fire/Flying to Fire/Dragon, eliminating the Stealth Rock weakness. Plan your team around these changes.
- Speed ties: Mega Evolution boosts Speed, but the Speed boost only applies after the first turn. Plan accordingly.
Mega Raids Guide
In Pokémon GO, Mega Raids are special raid battles that reward Mega Energy. You need Mega Energy to Mega Evolve your Pokémon in Pokémon GO. The amount of Mega Energy needed varies by Pokémon, with newer Mega Evolutions typically requiring more.
Once Mega Evolved in Pokémon GO, the Pokémon stays in its Mega form for 8 hours. During this time, it boosts the attacks of other Pokémon in raids by 10%, and boosts attacks of the same type by 30%. This makes Mega Pokémon invaluable for raid battles.
