How To Beat Sierra In Pokémon GO (December 2023)

The best way to beat Sierra in Pokémon GO in December 2023 is to know her possible lineup in advance and prepare your team to counter all or most of her creatures. Sierra is one of the three leaders of the Team GO Rocket organization, along with Arlo and Cliff in Pokémon GO. While kept in the same status as her colleagues, Sierra seems to be the closest to Giovanni, the head of the criminal group.

Although it is not too often, leaders of Team GO Rocket occasionally change their lineup, which requires Trainers to adapt accordingly. The strategy to beat Sierra in November 2023 has changed slightly, as she altered one of the possible Pokémon in her lineup. Although the change is not too drastic, it does impact how you prepare your team to counter her. Luckily, Sierra swapped out a Pokémon that was relatively challenging to counter for one that is much easier.

Best Counters For Sierra In Pokémon GO (December 2023)

As registered by Bulbapedia, there was a slight change in Sierra’s lineup in Pokémon GO. The change occurred on November 14, which ultimately impacted her lineup in December – or, at least, a portion of the month. Most of her Pokémon picks, however, remain unchanged. If you are intent on obtaining a high-ranking Shadow Sableye or a Shiny Shadow Sableye, you can still try to beat Sierra and capture the creature.

Sableye is still her first pick in her lineup and, until the next definitive change, this will always be her first Pokémon. Sableye’s only weakness is Fairy-type, so a powerful Togekiss or Sylveon are the best counters.

Sierra’s second Pokémon can be one of three possible options. In December, the Team GO Rocket leader may use Skarmory, Muk, or Gardevoir. To beat the Steel- and Flying-type creature, you will need to use an Electric- or Fire-type counter. Muk is weak against Ground- and Psychic-type attacks, while Gardevoir is weak against Ghost-, Poison- and Steel-type attacks.

The issue with Sierra’s second pick in Pokémon GO for now is that there is no overlap in weaknesses across her creatures. As such, you will need to prepare a Pokémon to counter one of them, at the risk of her choosing another.

If Sierra ends up choosing a Pokémon that has a weakness that is different than that of the creature you choose to counter her, you may have to challenge her again.

The change in Sierra’s lineup occurred in her third slot, where she took out Kingdra and replaced it with a Victreebel. This is good since Victreebel has a lot more weaknesses – Flying-, Fire-, Psychic-, and Ice-type moves are strong against it. The other two possible Pokémon for her third slot remain unchanged: Gyarados and Houndoom. The table below lists all of Sierra’s possible picks in Pokémon GO during December 2023, as well as their weaknesses and suggested counters:

Because some of Sierra’s slot Pokémons’ weaknesses overlap with her second picks’ weaknesses, you may want to use a party composed of a Fairy-type, an Electric-type, and a Ground-type Pokémon. This should give you a lot of coverage, though you may be required to adapt your strategy depending on her picks.

Though there is an off-chance that you may have to face her more than once, beating Sierra in Pokémon GO in December 2023 is not much of a challenge in comparison to a few of her previous lineups.
