One of the formidable Team Go Rocket Leaders in Pokemon Go, Sierra presents a challenging battle for Trainers seeking to prove their skills. So, to make things a little easier, here are all the details regarding her lineup, weaknesses, and the best counters to use in January 2024.
In the world of Pokemon Go, Trainers can grab Mysterious Components by defeating Team Go Rocket Grunts at invaded PokeStops. Once you have six of them, you’ll be able to construct a powerful Rocket Radar, leading you straight to the Team Go Rocket Leaders.
However, unlike the Grunts, who can be taken down with relative ease, the Team Go Rocket Leaders present a far more demanding challenge. There are three in total: Cliff, Arlo, and Sierra, each boasting their own arsenal of unique Pokemon to engage in combat.
This guide is dedicated to taking down Sierra, detailing her current lineup for January 2024, along with invaluable advice on the ideal counters to swiftly secure victory.
Update: Pokemon Go recently revealed a new event called Taken Treasures will go live on Saturday, January 27, 2024, from 12:00 AM local time, until Thursday, February 1, 2024, at 11:59 PM local time. The event will feature plenty of Shadow Pokemon, so we can expect some changes in Sierra’s lineup. We will update this guide once they are confirmed.

Best team to defeat Sierra in Pokemon Go
Having the right team is key to beating Sierra.

One of the best teams you can use when battling Sierra in Pokemon Go consists of Gardevoir, Primarina, and Electivire. Be aware that this team isn’t going to work in every scenario, so it’s more of a general recommendation that you can shake up as needed.
The most important thing you can have on your team is Fairy-type Pokemon like Gardevoir. It will help you get rid of Sableye fast, plus it also works nicely against Muk.
Then you must have a strong Water-type like Primarina, as this will be able to take down Sierra’s Gyarados and Houndoom, as well as her own Gardevoir.
Fighting Skarmory is the trickiest portion of the encounter, so you can go ahead with an Electric-type Pokemon like Electivire to take advantage of its weakness. A Fire-type Pokemon like Blaziken also works, as it’s strong against both Skarmory and Victreebel.
Our best advice is to take in two of your strongest Pokemon so you have a chance of winning through sheer force. Even if you lose, you’ll then know what Sierra’s lineup is so you can plan a better team using the counters in this guide ready for a rematch.
