Honestly, if you haven’t checked your Rocket Radar lately, you’re in for a rude awakening. Sierra has always been the "technical" leader of the trio, but the Sierra Pokémon GO March 2025 rotation is particularly nasty if you're going in blind. We’ve seen her cycle through some easy wins in the past, but right now? She’s packing heat that punishes anyone relying on old, dusty "recommended" teams from two years ago.
You’ve probably noticed the shift.
The current Season of Max Out has reached its peak, and the Team GO Rocket takeovers have become more frequent, yet Sierra remains the gatekeeper for some of the most sought-after Shadow Pokémon in the meta. If you’re hunting that elusive Shiny Shadow or just trying to clear your "A Seven-Colored Shadow" or seasonal research, you need to stop button-mashing through her first slot.
The Lead: Shadow Ralts and the Early Game Trap
It all starts with Shadow Ralts. Don't let the low CP fool you. While Ralts itself isn't a tank, the fast move pressure from Charm can shred a Fighting-type lead before you even realize you've made a mistake. Most players default to a Lucario or a Machamp lead because they’re used to Grunts. Do that against Sierra this month, and you’re burning a shield in the first ten seconds.
The trick here is poison or steel. Simple as that.
Metagross with Bullet Punch and Meteor Mash is the gold standard, but I’ve been having a weirdly good time using Nihilego. The Poison Jab pressure is insane. You want to farm energy on Ralts. Since Ralts is squishy, you can usually get away with not using a Charged Attack at all, or perhaps just one bait, to bank energy for whatever nightmare she sends out next.
What’s Lurking in Slot Two?
This is where the Sierra Pokémon GO March 2025 experience gets unpredictable. She’s currently rotating between Shadow Steelix, Shadow Sableye, and sometimes Shadow Milotic depending on the specific event window.

Steelix is the run-ender.
If she drops Steelix, and you brought a Fairy-type to counter her Sableye, you’re basically toast. Steelix has massive bulk. You need a dedicated "shield breaker" here. I usually keep a Swampert with Hydro Cannon in the back just for this moment. The spamminess of Hydro Cannon forces Sierra to burn her two shields early. If you don't clear those shields during her second Pokémon, her third will absolutely steamroll you.
Sableye is a different beast. Since it’s only weak to Fairy, you’d think a Togekiss would be the play. It is, mostly. But remember that Shadow Sableye hits surprisingly hard with Foul Play. If you’re not careful, you’ll find your "counter" fainted with a full energy bar. It’s frustrating. It’s annoying. It’s classic Sierra.
The Heavy Hitters: Closing the Fight
By the time you reach her third Pokémon—usually Shadow Gardevoir, Shadow Houndoom, or Shadow Victreebel—you’re likely out of shields.
Shadow Gardevoir is the most common closer this March. If you didn't bring a Steel-type, you might as well exit the battle and restart. Charm hurts. It hurts a lot. Even at a type disadvantage, the raw damage output of a Shadow Gardevoir can delete a neutral attacker in five or six hits.

When the battle starts, or right after a Charged Attack, the AI pauses for about two seconds. You have to exploit this. If you swap your Pokémon right as the battle starts, you get two "free" fast moves where Sierra’s Pokémon just stands there like a confused turtle. In a high-stakes match against her Shadow Houndoom, those two extra Snarls or Mud Shots can be the difference between getting your move off or dying with a full circle.
Why Shadow Carvanha (Still) Matters
Many players are asking why they should even bother with Sierra in Pokémon GO March 2025 if the rewards feel stagnant. Here’s the deal: Shadow Sharpedo is a glass cannon king in certain Great League formats and a monster for speed-running raids. While we’ve seen a shift toward Ralts being her primary lead for the Shiny hunters, the potential for high-IV Shadow Gardevoir for Fairy-type raid attackers is the real prize this season.
Gardevoir (Shadow) currently sits near the top of the DPS charts for Dragon-type raids. If you’re preparing for the upcoming Primal or Mega raids later this spring, you need a functional team of these. Fighting Sierra isn't just about the 500 Stardust or the 12km Egg; it's about the long-term resource grind.
Real Talk: Budget Counters That Actually Work
Not everyone has a Level 50 Shadow Mewtwo or a maxed-out Dialga. I get it. If you’re a mid-level player trying to survive March 2025, you need the "working man's" team.
- Magnezone: Spark and Wild Charge/Mirror Shot. Mirror Shot is great for baiting shields and lowering Sierra's attack. It’s cheap to build and resists a lot of what she throws.
- Roserade: If she’s running Milotic or Steelix, Roserade with Leaf Storm can do some heavy lifting, though it’s fragile.
- Excadrill: Mud Shot and Drill Run. This is your Steelix killer. It’s fast, it’s mean, and it’s relatively easy to find Drilbur candy right now.
Avoid using Dragon-types. Sierra's affinity for Fairy moves makes Dragons a huge liability. You’ll see people on Reddit claiming they "swept her with Garchomp," but they probably got lucky with her move set or had a massive level advantage. For the average player, Dragons are a trap.
The 12km Egg Dilemma
Winning the battle is only half the story. March 2025 has seen a slight tweak to the 12km "Strange Egg" pool. Salandit is still the "holy grail" here, specifically the female one for Salazzle. If you have an open egg slot when you defeat Sierra, you’re pulling from a pool that includes Vullaby, Larvitar, and Pawniard.

Is it worth the hassle? If you’re still hunting for a hundo Tyranitar or a competitive Bisharp (Kingambit), then yes. If you’re full on eggs and don't want to buy incubators, honestly, you might want to skip the Leaders and just focus on Grunts until you have space. There’s nothing worse than beating a tough Sierra lineup and getting zero egg rewards because you forgot you had a 2km egg from a PokéStop sitting in your last slot.
Common Misconceptions About Rocket Leaders
I hear this a lot: "The Leaders get harder as you level up."
Sorta. Their Pokémon’s CP scales with your trainer level, but their AI remains the same. They always shield the first two Charged Attacks you throw. Always. Use this to your advantage by throwing your lowest-energy cost move first, even if it’s resisted. Get those shields out of the way so your "nuke" move actually lands on their second or third Pokémon.
Another myth is that the Shiny rate is higher if you beat them at night. Complete nonsense. The Shiny rate for Shadow Pokémon from Leaders is estimated to be around 1 in 64, regardless of the time of day or whether you used a Potion before the fight. It’s just RNG.
Final Prep for Your Encounter
Before you tap that balloon or walk to that PokéStop, check your lineup one last time. Does your lead have a fast move that generates energy quickly? Do you have a plan for a Steelix swap?
March 2025 is a transition month. We are moving toward the massive summer events, and the difficulty spike in Rocket Leaders usually signals a shift in the meta. Sierra isn't impossible; she’s just demanding. She wants you to respect the typing.
Actionable Next Steps:
- Audit your Steel-types: Ensure you have at least one Metagross or Melmetal ready. Melmetal is particularly good because you can get the Mystery Box for free, making it the easiest "expert" counter to max out.
- Clear an Egg Slot: If you are hunting Salandit, do not spin a Stop or open a gift until you’ve cleared Sierra and secured that 12km egg.
- TM Away Frustration: If there is a Team GO Rocket Takeover event scheduled for late March, save your best Shadow Ralts or Shadow Beldum. You cannot remove the move "Frustration" except during these specific windows. Mark them with a tag in your storage so you don't forget.
- Practice the "Ghost Swap": Go into a battle with a Grunt and practice swapping your Pokémon the second the fight starts. Get a feel for those two seconds of AI lag. It is a mandatory skill for beating Leaders without burning through your entire Potion stash.
Sierra is a hurdle, but with the right Steel and Poison coverage, she’s basically a delivery service for high-tier Shadow Pokémon. Stay sharp.
