Sierra and the other Team Rocket Leaders in Pokémon Go have returned to cause even more trouble for June 2021. Right now, they appear to have the same roster they were using at the end of the Luminous Legend Y event from May. However, Giovanni is set to receive a new shadow Pokémon on June 17, and because of this change, we can expect to see a new roster for Sierra, Arlo, and Cliff. For right now, they’re all using the same Pokémon.
If you’re looking for Sierra or the other two Team Rocket leaders, you’ll need a Rocket Radar, which you can receive after defeating six Team Rocket grunts. These grunts drop the mysterious components that automatically combine into the radar. You’ll be able to narrow down the location of the Team Rocket leader’s hideout and battle them.
Here are all of Sierra’s Pokémon, their weaknesses, and the best Pokémon to use against her.
The first Pokémon Sierra is using is Sneasel, a Dark and Ice-type Pokémon. It’s going to be weak against Bug, Fairy, Fighting, Fire, Rock, and Steel-type attacks, but it’s resistant against Dark, Ghost, Ice, and Psychic-type moves. You primarily want to focus on using Fairy, Fighting, Fire, or Steel-type attacks to defeat it. We recommend you use Talonflame, Perrserker, Galarian Stunfisk, Machamp, or Clefable to beat it.
This Pokémon does have a chance to be a shiny version when you beat Sierra.
This is the second Pokémon Sierra might use against you for her second Pokémon choice.
- Gliscor (Ground and Flying-type)
- Granbull (Fairy-type)
- Ampharos (Electric-type)
Given what we know about Sierra’s roster, this group is primarily weak to Ice and Water-type attacks. Ice would be your best option to take out Gliscor, and not be left super effective against Ampharos if Sierra uses that Pokémon. You could always go with Mamoswine, giving this Pokémon a Ground-type option.
These are the final Pokémon choices Sierra might use against you as her third pick.
- Houndoom (Dark and Fire-type)
- Kingdra (Dragon and Water-type)
- Drapion (Dark and Poison-type)
Given her choices, these Pokémon will be weak to Dragon, Fairy, Fighting, Ground, or Rock-type moves. You primarily want to focus on using Dragon, Fairy, Fighting, Ground, or Rock-type Pokémon. We highly recommend you consider using Galarian Stunfisk, Escavalier, Sirfetch’d, Machamp, Heracross, Articuno, and others that fit these choices.
Once you’ve defeated Sierra, you’ll have the chance to capture her shadow Sneasel and evolve it into a Weavile. It does have a chance to be shiny.
