It would seem that Pokémon GO’s Festival of Lights celebration and Professor Willow’s research on the Mythical Pokémon Hoopa have attracted some unwanted attention. Starting Tuesday, November 9, 2021, Team GO Rocket will arrive to take over the event in an attempt to capture Hoopa. The villains are led by Giovanni, who’s ready to battle alongside his newest Shadow Pokémon, Shadow Lugia.

When Team GO Rocket’s takeover begins, you’ll find their members more frequently at PokéStops and in balloons. The Team GO Rocket Grunts and their leaders—Cliff, Sierra, and Arlo—might even be using different Shadow Pokémon than their usual to disrupt the festivities. During this event, you can use a Charged TM to help a Shadow Pokémon forget the Charged Attack Frustration. And if you’re lucky, you might even encounter a Shiny Shadow Pokémon.

As you take on Team GO Rocket, you can use the Super Rocket Radar from Special Research to encounter Giovanni himself. Defeat him, and you can rescue Shadow Lugia.

When you’re not dealing with Team GO Rocket trouble, be sure to check your Field Research Tasks, in which you’ll be able to encounter Vullaby. Plus, for the first time in Pokémon GO, you’ll be able to find a Shiny Vullaby, if you’re lucky.

Will light defeat the shadow of Team GO Rocket? You can help see that it does by continuing to enjoy Pokémon GO’s Festival of Lights celebration, which concludes on Sunday, November 14, 2021, at 8:00 p.m. local time.
