Team GO Rocket Leader Sierra returns in October 2023 with a fresh lineup of Shadow-type Pokémon in . However, with multiple types of Pokémon at her disposal, taking down Leader Sierra will be a formidable challenge that will put any trainer's Pokédex to the test.
In any case, you should challenge Leader Sierra because you can earn 1,000 Stardust, catch one of the leader's Shadow-type Pokémon, and a Team GO Rocket exclusive 12km Strange Egg. Better yet, defeating Sierra brings you one step closer to confronting Team GO Rocket Boss Giovanni in .
If at least one of your Egg inventory slots is open when you defeat Team GO Leader Sierra, then it is guaranteed you'll get a 12km Strange Egg as a reward.
The first Pokémon in Sierra's lineup that every trainer must face is Generation 1 Shadow Geodude. Following that, you'll either face off against Steel- and Ground-type Steelix, Psychic- and Fairy-type Gardevoir, or a Dark- and Ghost-type Sableye. In the third and final wave, you'll have to take down either a Dark- and Fire-type Houndoom, Water- and Flying-type Gyarados, or a Grass- and Poison-type Victreebel, according to PokemonGoHub.
