Sierra’s Shadowy Comeback: A New June Lineup in Pokémon GO
Hold onto your Poké Balls, trainers! Team GO Rocket’s enigmatic leader Sierra has returned this June 2025, and she’s got a brand-new roster that packs a serious punch. After months of familiarity, Sierra—with her trusty sidekicks Cliff and Arlo—has undergone a fierce makeover just in time for the Crown Clash: Taken Over event. If you think battling AI opponents is a stroll in the park, think again. This month, it’s all about strategy, and Sierra’s lineup of seven formidable Shadow Pokémon is here to challenge even the most seasoned players.
A Fresh New Team of Shadows
Sierra’s revamped team includes some stunning additions that will make you rethink your battle strategies. Here’s a quick peek at what you’ll face:
- Lead Pokémon: Always starting strong with Trapinch (Ground-type)
- Middle Pokémon: A wild card trio featuring Staraptor (Normal/Flying), Mismagius (Ghost), or Ferrothorn (Grass/Steel)
- Final Pokémon: Expect a surprise with either Camerupt (Fire/Ground), Drapion (Poison/Dark), or Houndoom (Dark/Fire)
With these dynamic types, Sierra is not just throwing out random Pokémon; she’s strategizing for victory!
Countering Sierra’s Shadow Squad
The key to taking down Sierra lies in understanding her team’s weaknesses. Here’s a breakdown of effective counters to help you climb the ranks:
- Trapinch: Weak to Grass, Ice, and Water? Bring in Swampert, Kyogre, or Mamoswine!
- Staraptor: With its vulnerability to Electric, Ice, and Rock, unleash your Tyranitar or Terrakion.
- Mismagius: A good ghostly foe, counter with Tyranitar or Gengar—they’re ready to give it a run for its money.
- Ferrothorn: This Grass/Steel hybrid can’t stand the heat from Charizard or Blaziken.
- Camerupt: For this fiery Ground-type, hit back with the likes of Swampert or Groudon.
Ready for a curveball? Swampert shines against four out of five of Sierra’s Pokémon, making it a must-have in your lineup!
Sweet Rewards Await
Once you’ve bested Sierra, there’s a treat waiting for you. Defeating her guarantees an encounter with a Shadow Trapinch. Capture it to evolve into the menacing Shadow Flygon, a Dragon/Ground-type powerhouse that can seriously amp up your roster.
But wait, there’s more! Every win against Sierra unlocks the chance to snag the coveted 12km red eggs—a prized possession for any dedicated trainer.
Reminder: This encounter is your ticket to eventually challenging the notorious GO Boss Giovanni, adding a layer of excitement to your gameplay.
With a little strategy and the right counters, Sierra’s new June team may just turn out to be less of a shadowy nightmare and more of a thrilling challenge. So gather your Pokémon, sharpen those skills, and jump into the action. Adventure awaits, trainers!
