Trainers,
The new legendary Pokémon are almost here! From July 22, at 1 PM PDT, you will be able to find new strong Pokémon like Mewtwo and other legendaries of the regions of Kanto and Johto. This new Pokémon will be released for the first time on Pokémon GO Fest, and will be released to the public once the GO Fest Pokémon finishes.
We have also added new features to enhance your experience.
- Legendary Pokémon: These extremely rare Pokémon will first reach Pokémon GO Fest, in the form of level 5 raids. In order to successfully defeat the legendary Pokémon, you and your friends will have to unite to gain the chance to capture the legendary Pokémon Extremely rare. But keep in mind that these Pokémon will be extremely difficult to catch, so be sure to save some extra berries for it!
- Additional Items: There will be additional items added to the game including but not limited to: Master Balls and Golden Pineapple Berries. Most of these items will come as drops and will be extremely rare to defeat the powerful Raid Boss! The new Master Ball will be extremely rare after defeating an Incursion Boss. Using the Master Ball, you will have a guaranteed catch! Use it wisely, since you can not get another one for a long time after!
- Certain drinks can be found by turning the photodisc in Poképaradas. These berries allow you to double the amount of Dust generated by catching a Pokémon. By using Golden Pineapple Berry, you can increase the amount of candy by catching a Pokémon. These berries can be found very little by defeating an Incursion Boss.
- Limited time Pokemon: For a limited time, with sunny days coming, we thought there would be no better time for the party with Squirtle Squad! Squirtles around the world will catch your eye with some new sunglasses! Pokémon will keep their sunglasses on forever, so stay tuned for limited-time Pokémon.
- New Clothes: With the next release of Legendaries just around the corner, there will be some new clothes to choose from! Customize your look with a whole new selection of legendary-themed apparel!
- Pokémon IVs: Once you have evaluated your Pokémon once, you will soon be able to keep track of the rating of your Pokémon! Depending on the evaluation of your Pokémon, your Pokémon will have a red scheme with a not so good evaluation, or green with an incredible evaluation! This environment will remain in your Pokémon forever, so you will not have to evaluate more than once.
We are sure to bring you more information in the coming weeks.
We can not wait to see the legendary Pokémon you catch!
