Sierra is one of three Team GO Rocket Leaders that Trainers can encounter and battle with a Rocket Radar in Pokémon GO, alongside Cliff and Arlo. These three boss fights are very difficult if you don't come prepared, so if you're taking on Sierra, it's important to know her current lineup, their weaknesses, and the best counters to beat them all.

As part of the Adventure Week: Taken Over event in August 2024, the lineups of Team GO Rocket have been shaken up. Sierra is no exception, with some powerful Shadow Pokémon like Carvanha, Ampharos, and Houndoom having the potential to appear on her team. As long as you take the best team possible into battle, though, you should be able to emerge a winner.

Pokémon GO Sierra Lineup & Counters In August 2024

Be Prepared For Battle

Sierra will always send the Dark/Water-type Carvanha into battle first, which makes this a fairly easy stage to prepare for. However, her second and third Pokémon can be one of three different options, so planning ahead for these will be a little more difficult. What you can do, though, is put together a strong team that has as much coverage as possible for the best shot at success.

You can see Sierra's full potential lineup (thanks to LeekDuck for the help with this information), their weaknesses, and the best counters to defeat them in the table below:

, Sierra will only send out one Pokémon from each wave. These will be chosen at random, but once you've started a battle with her at a specific PokéStop or Rocket Balloon, her team will remain the same when you rematch her. Think of your first battle as a reconnaissance mission where your main goal isn't to defeat her, but to figure out which Pokémon she's using. This will help you put the right team together.

Best Team To Beat Sierra In Pokémon GO

Gardevoir, Mamoswine & Electivire

One of the best teams you can use to beat Sierra in Pokémon GO right now is Gardevoir, Mamoswine, and Electivire. There's no such thing as a perfect team, as that will always depend on which lineup she uses, but these three Pokémon have coverage against the majority of Sierra's potential team.

A powerful Fairy-type Pokémon like Gardevoir should be first up on your team, as this can take out Sierra's guaranteed first Pokémon, Carvanha, as well as wave two's Sableye, which is only vulnerable to Fairy-type attacks.

Next up, it's important to have a strong Ground-type Pokémon, because Sierra's wave two Pokémon could be Ampharos, which is only weak to Ground-type attacks. Mamoswine is a good shout here, as it can also defeat two of Sierra's potential wave three team : Houndoom and Nidoqueen. Your final team member is up for debate, but a good Electric-type like Electivire can take on Milotic as well as Carvanha if needed.

The only Pokémon not covered by this team is wave two's Alakazam, but if Sierra does send that Psychic-type into battle, you can switch Electivire out for a Dark-type Pokémon like Hydreigon and battle her again. You can rematch as many times as you want using a single Rocket Radar, so don't worry about losing on your first few attempts. Keep trying different teams and you'll get there.

Some other ideal teams for taking on Sierra would be Togekiss, Garchomp, and Magnzeone, or Xerneas, Excadrill, and Xurkitree.

Rewards For Defeating Sierra In Pokémon GO

Catch A Shadow Pokémon

The main reward for defeating Sierra is a chance to catch her team's first Pokémon, which in this case is a Shadow Carvanha. Being a Shadow Pokémon makes it more powerful in battle, and there's also a chance you could encounter a Shiny variant, too. Unfortunately, both Carvanha and its evolution Sharpedo are quite useless in the Pokémon GO Battle League and as attackers in Raid Battles, so it's not the most exciting reward.

Still, it's a chance to add another Shadow Pokémon to your collection. Other rewards include a handful of Stardust, as well as some random items, which could include an Unova Stone. Finally, if you have a slot free in your Egg storage, you'll get a 12 KM Egg, also known as a Strange Egg. These red-spotted Eggs have some of the rarest hatches in Pokémon GO, including Salandit, Larvitar, and Varoom.
