Rayquaza is already one of the most fearsome Legendary Pokémon you can add to your collection in Pokémon Go, making it a highly sought-after choice. You can make it even more powerful by evolving it into its Mega Rayquaza form, but getting there takes some work.

Unlocking Mega Rayquaza's form will take time. You'll also need to be patient as you wait for specific events to occur. You'll need to use Mega Rayquaza energy to evolve it, and you'll also need to track down a specific item to make it happen. Without this item in Pokémon Go, you won't be able to evolve your Rayquaza into Mega Rayquaza.

You can only evolve a Rayquaza into a Mega Rayquaza if it learns the charged move Dragon Ascent. This is not a standard charged move in Pokémon Go. Instead, Rayquaza will only learn how to use Dragon Ascent if you give it a Meteorite, a special item that can be obtained through events or Special Research tickets. These are available in Pokémon Go at certain times, usually provided by Niantic.

For any Pokémon Go players looking to teach their Rayquaza how to use Dragon Ascent, they’ll need to take part in the latest Mega Rayquaza event. It’s taking place on August 3rd from 11:00 to 17:00 in your local time zone. It’s a catch-up event for the previous Mega Rayquaza Elite Raids, which didn’t go as planned. Now, when you log into the game, there’s a free Special Research available to all players. You’ll need to work your way through this free research, and one of the rewards for completing it is a meteorite.
