Team GO Rocket Leaders are enemy battles that can be challenging for Trainers to overcome in Pokémon GO; however, it can be rewarding. Defeating Arlo, Cliff, and Sierra will lead to the showdown with their boss, Giovanni, but before that, you'll need to go head-to-head with each leader.

Sierra is one of the three leaders you must face; however, she's no pushover, as her line-up could overwhelm you if you're not prepared or underpowered. This guide details Sierra's current line-up and the best counters, including Pokémon, their typing, and attacks to use against her in Pokémon GO.

2nd November 2023 Update: This guide reflects the new Pokémon lineup and possible counters when encountering Team GO Rocket leader Sierra in battling encounters during Pokémon GO's Season of Adventures Abound. The original reporting continues below.

Team GO Rocket Leader Sierra's line-up, like Arlo and Cliff, hasn't changed following the previous Rising Shdaows event, which introduced Shadow Raids in-game. While she and all Team GO Rocket Leaders and their boss, Giovanni, have Shadow Pokémon included in his line-up, Trainers will need to adjust their line-up to fit the best possible counters.

Below is the current Shadow Pokémon line-up for Team GO Rocket Leader Sierra for November 2023, with all data supplied by notable Pokémon source, PokémonGOHub:

  • Sierra Battle Phase 1: Sableye
  • Sierra Battle Phase 2: Gardevoir / Muk / Skarmory
  • Sierra Battle Phase 3: Gyarados / Houndoom / Kingdra

Best Sableye Counters:
