For March 2025, Team GO Leader Sierra is back inPokémon GOto stop players in their tracks. Changes may be afoot inPokémon GOwith the current season, Dual Destiny, ending on March 4, but Team GO Rocket will still cause problems for trainers. Despite changes in January, Sierra returns with the same line-up from February. This may change throughout the month when the new season starts, but for now, she will start March 2025 with the same seven Pokémon as in previous months.
After defeating six Team GO Rocket Grunts, likePokémon GO’s Ke Ke Ke,you will be able to face one of the three Team GO Rocket Leaders. Once you are at this stage, each time you spin a Poké Stop Team GO Rocket has taken over or a Rocket balloon, you will encounter one of the Leaders at random: Sierra, Arlo, or Cliff. Once you find Sierra, you will be in for a tough battle that you have to enter prepared for, or you’re able to quickly be swept aside, even if you have faced off against her before.

Sierra’s Team & Counters In Pokémon GO (March 2025)
No Changes For March 2025
If you have faced Sierra in February, you are in for no new surprises, but it is vital you know the team that she will use. The Leader will always start withPoison- and Bug-type Skorupi. Her following two choices will be one of three options selected at random.
Sierra’s second and third waves of Pokémon will always be randomly selected and will change each time you challenge her. So, if you are struggling, you’re able to exit the battle and try your luck against a different line-up next time.

Sierra’s second Pokémon will be eitherWater-type Milotic, Fire-type Ninetales, or Steel- and Grass-type Ferrothorn. Following this, her final Pokémon will be one ofDark- and Fire-type Houndoom, Poison- and Ground-type Nidoqueen, or Poison- and Dark-type Drapion.Whichever Pokémon are selected will all be given a stats boost as a shadow variant, making them tougher to defeat.
Pokémon and type

Ground
As Sierra will always lead with Skorupi, you should use a Fire-, Flying-, Psychic- or Rock-type Pokémon, which will give you an advantage over it. My personal choice currently isLegendary Fire-type Ho-Oh. By selecting a Fire-type, you may make quick work of Skorupi, as well as Sierra’s potential second Pokémon, Ferrothorn, who is only weak against Fire-types, and Ho-Oh is one of the best choices to do this.
Pokémon GO: Best Teams For Great League and Master League: Mega Edition
There are options in The Great League and The Master League: Mega Edition in Pokémon GO, but you can win more matches by selecting the best teams.
Ground-types are key to this battle, with four of Sierra’s seven potential Pokémon being weak against it. The powerhouseGroudon iswidely regarded as one of the strongest Ground-types inPokémon GOand should be switched in when facing Ninetales, Houndoom, Nidoqueen, or Drapion as it is super-effective against them all.
Sticking with the Legendary theme, an Electric- or Grass-type Pokémon should be included as your third choice in case Sierra uses Milotic. My preference is Generation OneZapdos, as I have found it will quickly overpower the Water-type Pokémon. However, any strong Pokémon with one of these two types should be able to defeat it.
