Understanding Rogue Mega Pokémon

When you face a Rogue Mega Altaria, you deal with a wild Pokémon that triggers Mega Evolution without a trainer. These encounters are stronger than regular wild battles. During these events, you often receive help from an ally from Team MZ, giving you support while you work through the encounter and secure the Mega Stone.
