Defeating Sierra, one of the most challenging Team GO Rocket Leaders, requires a calculated strategy. Her current team features a guaranteed first Pokémon followed by two unpredictable phases. Understanding her lineup and preparing targeted counters is key to winning consistently.
Sierra’s Lineup Overview (May 2025)
Phase 1: Shadow Skorupi (Poison/Bug)
Phase 2 (one of three):
Shadow Ninetales (Fire)
Shadow Ferrothorn (Steel/Grass)
Shadow Milotic (Water)
Phase 3 (one of three):
- Shadow Houndoom (Dark/Fire)
- Shadow Nidoqueen (Poison/Ground)
- Shadow Drapion (Poison/Dark)
General Counter Strategy Begin with a Pokémon that can charge up fast and force Sierra to use both of her shields early in Spark or Sierra Pokemon GO battles. Then, switch to high-damage counters tailored to each phase of her lineup. It’s also essential to bring a versatile Ground-type, as many of her Pokémon are weak to Ground attacks.

2. How to Beat Sierra in Pokémon GO – Best Pokemon
Winning against Sierra Pokemon GO requires a mix of powerful counters, smart switching, and timing. If you're looking for how to beat Sierra Pokemon GO, keep in mind that her lineup changes in phases, so preparing a team that’s effective across all potential matchups is crucial.
1. Break Her Shields Quickly
Start with a Pokémon that uses a fast-charging quick move and a low-energy charged move. Mewtwo with Psycho Cut and Psystrike is a top choice, allowing you to trigger Sierra’s shields in the opening seconds.
2. Prepare for Flexible Matchups in Phase 2
Each of Sierra’s Phase 2 Pokémon has distinct weaknesses:
- If she sends out Ninetales, switch to a Water or Ground-type such as Swampert or Garchomp.
- Against Ferrothorn, Fire-types like Heatran or Charizard will perform best.
- If she uses Milotic, bring in Electric-types like Zapdos or Magnezone.
3. Be Ready for a Tough Final Battle
Her third Pokémon often deals heavy damage. Use durable and type-effective counters:
- Against Houndoom, bring Fighting or Ground-types like Machamp or Groudon.
- For Nidoqueen, Psychic-types or Ice-types such as Mewtwo or Mamoswine work well.
- Drapion is only weak to Ground, so keep a powerful Ground-type like Garchomp or Rhyperior in your team.
