How to find Sierra in Pokémon GO?

Rocket Radar

To fight with Sierra in Pokémon GO, you need to first defeat six Team GO Rocket Grunts to collect enough Mysterious Components to build a Rocket Radar.

Activate the Rocket Radar and you will be able to see the location of a Rocket Leader. The game will not tell you which Leader you are facing, but you have a 33% chance for it to be Sierra.

Fighting Sierra is more difficult than fighting Grunts, as Leaders use higher level Pokémon than Grunts. In order to defeat Sierra, we consider using good counters mandatory. 

You can rematch if you lose, and your Rocket Radar will be consumed if you win.

Rewards for defeating Sierra

Trainers who manage to defeat Sierra – or any other Team GO Rocket Leader – will get a selection of rare rewards, including the chance to get a Team GO Rocket exclusive 12 km Strange Egg.

  • Trainers receive 1,000 Stardust when defeating a Rocket Leaders,
  • Trainers will receive two of the item bundles listed below when they defeat Team GO Rocket Leader like Sierra.
  • Trainers have the opportunity to catch a Shadow Pokémon used by the Leader. It is always the first Pokemon used by the Leader.
  • Shadow Pokémon from Rocket Leaders have a shiny chance of 1 in 64, if they are shiny eligible at the moment of defeating the Leader

Reward mechanics

Defeating one of the Team GO Rocket Leader trio earns you two item bundles. If at least one of your Egg inventory slots is open, a 12km Strange Egg is guaranteed to replace one of those two bundles.

Receiving a Strange Egg does not have an effect on which item bundle drops alongside the egg.
