How to Beat Sierra in Pokémon Go: All Sierra Counters

Sierra? Piece of cake. Use the guide below to see the best counters against her Pokémon!

In Pokémon Go, you'll find that to get specific Pokémon, you'll have to defeat the Team GO Rocket grunts and bosses. The leaders (Cliff, Arlo, Sierra, and Giovanni) are often the most difficult, but provide the greatest rewards. In this guide, we will focus on how to defeat Sierra and which counters are best against her new Pokémon.

Quick Notes

  • This list is not permanent. Sierra's most recent lineup change was in May 2021. When her roster changes, so do the techniques and Pokémon you need to use to beat her. We strongly recommend you check back to this guide regularly to be up to date on the best ways to win!
  • Sierra's first Pokémon is always the same, but her second and third Pokémon alternate between two or three options. The first Pokémon she uses will always be Sneasel. For her second Pokémon, she will use Gliscor, Granbull, or Ampharos. For her last Pokémon, she will use one of these three: Kingdra, Houndoom, Drapion.
  • The counters we include aren't synonymous with weaknesses. Sometimes these counters will be mentioned for things other than being the opponent's weakness. Other examples may include their movesets or the fact that they're naturally resistant to their opponent.
  • These lists are not ranked from best to worst. While we can provide the best counters to use in any match, there is no guarantee which order they should fall. The effectiveness of each Pokémon largely depends on your play style and battle technique. This being the case, we have instead opted to list the counters alphabetically.
  • Sierra uses a variety of types. As the most challenging trainers go, Sierra doesn't focus on only one type of Pokémon. Still, the most frequent type you will encounter while battling her are Dark Pokémon, so avoid using Pokémon types that are weak against them, especially Psychic.
  • Best team setup: There are a few Pokémon types that we recommend adding to your team since they do well against many of the Pokémon in Sierra's lineup. It's best to have some combination of the team listed below. Still, if you only have two of them, you should hold fairly well against her.
    • Any Strong Ground Pokémon
    • Any Strong Fighting Pokémon
    • Any Strong Poison Pokémon
