Team Rocket Leaders like Sierra are exceptional trainers you can beat for rare rewards inPokémon GOin April 2025. This particular captain of the infamous criminal organization has multiple powerful Pokémon at her disposal, making her a challenge compared to any Team Rocket Grunts you’ve faced. You’ll need to form a squad of perfect counters to defeat Sierra’s team of Shadow creatures.
To even challenge Sierra, you need todefeat six different Team Rocket Grunts to assemble the Rocket Radar. This item will allow you to locate one of the three Team Rocket Leaders, either Sierra, Arlo, orCliff inPokémon GO. Although you only have an initial 33% chance of finding Sierra using the Radar, beating the other two leaders will help narrow down Sierra’s location eventually.

Sierra’s Team & Counters In Pokémon GO (April 2025)
Find The Right Match-Ups Against Shadows
Sierrahas a team of three Pokémonthat fight your team in three distinct waves. During the first wave, Sierra will always use the same Pokémon, but the second and third waves act a little differently. From my experience, Sierra always chooses her second and third Pokémon from three possible options, making it hard to predict which pocket monster she’ll send out after her first.

Each of Sierra’s Pokémon in every wave is a Shadow variant, meaning they have more health and do greater damage with their attacks. This makes choosing the right counters even more important, as you don’t want to give Sierra’s team a chance to fight back. If you have Shadow Pokémon of your own, they can be used in the battle against Sierra to match the power of her existing team members.

While the Sierra fight is challenging, it is not as difficult asMaster League battles inPokémon GO. Any Pokémon that thrives in that competitive atmosphere is likely to do well against the Team Rocket Leader too.
The following table goes over each potential Pokémon you could see on Sierra’s team, their weaknesses, and what counters may be the best against them:

Fighting, Ground, Rock, Water
If you factor in all the possible Pokémon Sierra might use, the following team has the best match-ups for every outcome:
Thebest counter against Sierra by a long shot is Swampert, whose Water/Ground typing gives it a huge advantage. With attacks like Mud Shot, Water Gun, and Hydro Cannon, Swampert can deal super-effective damage to Sierra’s Houndoom, Drapion, Nidoqueen, and Ninetales with ease. If you use a Shadow or Mega Swampert, you can bolster its attacks even further to potentially one-shot most of Sierra’s team.
Pokémon GO: Max Mondays Schedule (April 2025)
Max Mondays returns to offer a further four Dynamax Pokémon of varying difficulties for trainers to challenge across April 2025 in Pokémon GO.
Other strongdual-type Pokémon inPokémon GOlike Blaziken and Magnezone act as support for the rest of your team to counter Sierra’s other creatures. For example, if Sierra sends out her Milotic, Magnezone can use super-effective Electric-type moves to counter it. Blaziken in particular works well at the start of the fight, as it can defeat Sierra’s Skorupi with little effort.
