As promised, the reveal of Pokemon GO's Ultra Bonus reward arrived this morning. In a surprising twist, it turns out that two of the most popular theories about the reward are both coming true.

Pokemon GO trainers earned the Ultra Bonus by completing the tasks throughout the summer's three big in-person events. Thanks to all of that hard work, players are about to have the chance to catch more shiny legendary birds, see Mewtwo in non-EX Raids, and catch some of the regional Pokemon without leaving their hometown.

First off, here are the details about the returning Legendary birds and increased Kanto spawns...

"... Starting September 13 at 1:00 P.M. (PDT), Trainers all over the world will be able to encounter three Legendary Pokémon originally discovered in the Kanto region!. Articuno, Zapdos, and Moltres will appear in Raid Battles until September 20. And if you’re lucky, you may be able to encounter their Shiny forms! Also, Pokémon originally discovered in the Kanto region will appear more frequently all over the world and show up more frequently in Raid Battles until September 30!"

For many players who haven't had the chance to participate in a lot of EX Raids, the Mewtwo bonus is the most exciting part of this announcement. Here are the details on that...

"On September 20 at 1:00 P.M. (PDT), Mewtwo will come to Raid Battles for the first time ever! Mewtwo has previously only been available to Trainers invited to EX Raids, but now all Trainers will be able to challenge the Legendary Psychic-type Pokémon until October 23 at 1:00 P.M. (PDT)."

Although Mewtwo should be the most exciting part of the event, players who have already done tons of EX Raids, but no international traveling will likely be more hyped about the final bonus. Here's are the details on the incoming regionals...

"Farfetch’d, Kangaskhan, Mr. Mime, and Tauros will be joining the Alolan Pokémon in 7 km Eggs through the end of September! These Pokémon have not migrated to many parts of the world, so don’t miss this unique opportunity to send Gifts to friends and finally achieve a complete Kanto Pokédex!"

In many ways, this Ultra Bonus feels like the closing chapter to Gen 1. Obviously Gen 1 Pokemon will still exist in the game, but Niantic seems set on helping players finish that Kanto Pokedex so that they can move on to the next milestone.

Check back for more news and updates in the coming days. Until then, good luck out there, trainers!
