Niantic is shaking up Pokémon Go’s Max Monday schedule with the Legendary Flight event, which adds Dynamax versions of Articuno, Zapdos, and Moltres for the first time in the mobile game.

The upcoming Pokémon Go Legendary Flight event is providing a stage for Kanto’s legendary birds to debut in their Dynamax forms – but battling these mighty foes will be a daunting task.

Moltres, Zapdos, and Articuno may be appearing in Dynamax Raids from January 20 to February 3. The news was posted to the official Saudi Arabia Pokemon GO Twitter page but was quickly deleted.
