Pokemon GO has announced that Attack Forme Deoxys will be coming to the game in EX Raids later this week.

Get ready with some Ghost, Dark, and Bug type moves if you want to deal super effective damage.

Qualifying gyms can give you EX Raid passes when you beat a Raid Battle.

The DNA Pokémon, Deoxys, has tested the strength of Trainers in EX Raids and has now changed form! Attack Forme Deoxys will be in EX Raid Battles, with more power than previously seen, so make sure your team is prepared. This Psychic-type Mythical Pokémon will be available to challenge beginning with the next cycle of EX Raid invitations, after December 20.

Are you new to EX Raids? You can become eligible to receive an EX Raid Pass when you win a Raid Battle at a qualifying Gym. You’ll be able to see which Gyms can host an EX Raid through a handy tag when you look at the Gym details. EX Raid Passes will give you the date and time when you’ll be able to challenge Attack Forme Deoxys, so mark your calendar and prepare your Pokémon for an epic battle!

Battling Attack Forme Deoxys will be a difficult challenge that requires Trainers to take advantage of every opportunity—so don’t forget to invite a friend to go along with you! Remember: invites can only be sent to an Ultra Friend or Best Friend, so don’t forget to battle with friends, send Gifts, and trade Pokémon to build up your Friendship level.

Do you have what it takes? Best of luck, Trainer—Attack Forme Deoxys won’t back down!
