Dragonspiral Descent: Druddigon makes its Pokémon GO debut!

Tuesday, December 7, 2021, at 10:00 a.m. to Sunday, December 12, 2021, at 8:00 p.m. local time

The Season of Heritage Story Continues!

Success! A part of the mysterious door located at the historical cave site has been activated!

The rumbling caused by the movement of the door’s locking mechanism disturbed the Pokémon living within the cave—and with them appeared Druddigon, a Pokémon never before seen in Pokémon GO! Druddigon, the Cave Pokémon, is known to dwell within the Unova region’s Dragonspiral Tower.

Upon further inspection, Professor Willow has deduced that many of the emerging Pokémon are also known to call Dragonspiral Tower their home! Professor Willow also believes the unprecedented surge of Fire-, Electric-, and Ice-type Pokémon appearances may somehow be connected to Unova’s Dragon-type Legendary Pokémon: Reshiram, Zekrom, and Kyurem!

There’s no time to waste, Trainers—let’s investigate!
