Sierra Pokemon GO Lineup and Counters

Sierra's Team GO Rocket lineup shifts with nearly every season, and the version she runs right now decides which Pokemon actually win the fight. This piece lays out her exact current team, the best counter for each Pokemon she can send out, and a quick reference table you can screenshot before your next battle. Let's follow LDShop for more updated Pokemon GO Rocket guides like this one, since lineups rarely stay the same for long.

Sierra Pokemon GO Lineup (September 2026)

Sierra's first Pokemon is fixed. Her second and third slots rotate between three options each, so you need coverage, not just one strong attacker.

Shadow Amaura is currently the only Pokemon from this lineup you can catch after winning, and it carries a 1 in 64 chance of being Shiny. If you are wondering how it stacks up once evolved, our Pokemon GO tier list 2026 ranks it alongside the game's current top attackers.

Quick Guide: Sierra Pokemon GO Counters at a Glance

Use this table as your fast reference before you even open the battle screen in Pokemon GO.

If you want a single team that covers almost the entire lineup, run Lucario, Mamoswine, and Groudon. Mamoswine alone handles Flygon, Houndoom, and Steelix, and still does solid neutral damage to Ferrothorn. Need a stronger copy of any of these three first, our raid schedule guide shows when they are appearing as raid bosses this month.

Sierra Pokemon GO Phase 1 Counters: Shadow Amaura

Amaura mixes Rock and Ice typing, which gives it a double weakness to Fighting and Steel attacks. Lead with a Fighting type here, since Amaura can chew through shields fast if you hesitate.

Sierra Pokemon GO Phase 2 Counters: Flygon, Blastoise, or Ferrothorn

This slot rotates between three very different types, so flexibility matters more than a single specialist Pokemon. Flygon carries Ground and Dragon typing and drops fast to Ice moves. Blastoise is pure Water and folds against Electric or Grass attacks. Ferrothorn mixes Grass and Steel, and takes heavy damage from Fire.

Sierra's lineup usually shifts whenever a major crossover event lands, and the current one ties into our Pokemon GO x Pokemon Horizons celebration event guide, so keep an eye on that for any early lineup hints.

Sierra Pokemon GO Phase 3 Counters: Houndoom, Steelix, or Milotic

The final slot brings its own challenges. Houndoom pairs Dark and Fire, so Water, Ground, Rock, or Fighting moves tear through it. Steelix combines Steel and Ground, making it weak to Fighting, Fire, Ground, and Water attacks. Milotic is pure Water and folds against Electric or Grass moves.

Groudon works as a near universal pick for this phase, since it covers both Houndoom and Steelix cleanly.

Best Battle Strategy Tips to Beat Sierra in Pokemon GO

Picking the right counters only gets you halfway there. These habits decide the rest of the fight. Keeping a healthy stock of Poke Balls, Potions, and Raid Passes also matters during a Rocket takeover, and a quick Pokemon GO top up can save you a mid event scramble. If Sierra's fight is part of a paid event track, our Pokemon GO Pass guide breaks down exactly what it unlocks before you spend on it. The best platform to make the top-up is LDShop, it lets players top up for less and it is a great way to save money.

• Hold your first charge move rather than firing it immediately, since Sierra burns a shield on it and wastes the damage.
• Watch for the moment right after a charge move lands or a Pokemon faints and switches out. The opponent freezes briefly, so build extra energy during that window instead of attacking.
• Overcharge your energy bar whenever a charge move is already ready, so you walk into the next Pokemon with an immediate follow up hit.
• Match your Pokemon to Sierra's actual fast and charge moves, not just base typing, since move coverage can flip a battle either way.

How to Find Sierra in Pokemon GO

Defeat six Team GO Rocket Grunts at invaded PokeStops to collect Mysterious Components, then combine all six into a Rocket Radar. Activating the radar gives you roughly a one in three chance of encountering Sierra over Arlo or Cliff.

Rewards for Beating Sierra in Pokemon GO

Winning nets you 1,000 Stardust plus two additional reward bundles picked at random from items such as Hyper Potions, Max Potions, Revives, and occasionally a Strange Egg. Trainers holding fewer than 10 Purified Gems also receive 3 Shadow Shards. The bigger prize is the chance to catch Shadow Amaura once the fight ends, with a real shot at Shiny. Rocket takeovers also tend to line up with bigger celebrations, and our 10th anniversary event guide covers what else is worth grinding for right now.

Conclusion

Sierra's fixed opening Pokemon in Pokemon GO gives you a clear planning window, and her rotating second and third slots reward trainers who build flexible, type covering teams. Use the tables above, respect the shield mechanics, and Sierra turns from a wall into a routine win inside Pokemon GO.
