Mewtwo will arrive in the game for all very soon through 'Exclusive Raid Battles' - details below.

In the coming weeks, you, too, will have the opportunity to battle and catch Mewtwo with the new Exclusive Raid Battle feature.

Exclusive Raid Battles are similar to existing Raid Battles, with a few notable differences. Exclusive raids will periodically appear at Gyms around the world; however, unlike existing raids, Trainers will be invited to join an Exclusive Raid Battle. To receive an invitation to participate in an Exclusive Raid Battle, Trainers must have successfully completed a raid recently, by defeating the Raid Boss, at the Gym where the Exclusive Raid Battle will be taking place. The invitations will include advance warning of when the Exclusive Raid will take place, giving them ample time to coordinate with other Trainers before taking on the powerful Raid Boss.

Mewtwo is the first Pokémon that Trainers will be able to face in Exclusive Raid Battles, but other powerful Pokémon may also start to hatch from the Raid Eggs found at Exclusive Raid Battles over the next several weeks. Make sure you’re prepared to battle Mewtwo by powering up your Pokémon and battling in raids at Gyms near you!

Trainers attending a Pokémon GO event taking place in Japan over the weekend were treated to the first appearance of Legendary and fan favourite Pokémon Mewtwo. During the Pickachu Outbreak event, Mewtwo appeared at Yokohoma stadium with a ten hour raid window for players to gather and take down. Sporting the highest CP of any raid boss since the app's launch - at 49430 - the requirement to defeat Mewtwo seems to be leaning towards the maximum number of people needed - twenty. 

This is the first time the genetically created Pokémon has appeared in the game since launch and is the fifth legendary to materialise after Articuno, Zapdos, Moltres and Lugia all became available. Players have been reporting that they were given 50 Premier balls to capture the Pokémon, with others saying a 100% capture rate became apparent so that all attendees could grab the mythical creature. 

You can see screenshots below: 

With Zapdos rotating out of raid battles later tonight, does this mean Mewtwo is just around the corner for a global release? We'll have to wait for more information from Niantic.

How are you getting on with catching legendary Pokémon? Let us know.
