In Pokémon GO, few adversaries carry the same weight as Giovanni, the fearsome leader of Team GO Rocket. With every seasonal update, his lineup evolves, offering a new challenge for even the most seasoned trainers. June 2025 introduces a formidable roster during the Crown Clash Taken Over event, including the intimidating Shadow Dialga. This guide will walk you through every phase of Giovanni’s battle, including optimal counters and strategy tips for success.

🔍 Step One: Finding Giovanni (June 2025)

Before you can engage Giovanni in battle, you’ll need a Super Rocket Radar. This item is only obtainable by completing Team GO Rocket Special Research quests—often tied to time-limited events or monthly updates. Once acquired, activate the radar to locate Giovanni’s hideout. Be warned—his decoys will try to confuse you, so be prepared for multiple Rocket Grunt encounters before revealing the true boss.

🛡️ Giovanni’s June 2025 Shadow Pokémon Lineup

Giovanni always brings a lineup of three Pokémon:

• Round 1: Shadow Persian (Guaranteed)

• Round 2: One of the following

  • Shadow Rhyperior

  • Shadow Nidoking

  • Shadow Kangaskhan

• Round 3: Shadow Dialga (Guaranteed)

Understanding this structure allows you to build a solid, well-rounded counter team.

⚔️ Best Pokémon Counters to Beat Giovanni (June 2025)

Round 1: Shadow Persian

Giovanni always leads with Shadow Persian, a Normal-type that deals surprisingly fast damage.

Top Counters:

• Mega Lucario – Force Palm + Aura Sphere

• Mega Heracross – Counter + Close Combat

• Lucario – Force Palm + Aura Sphere

• Terrakion – Double Kick + Sacred Sword

• Mega Blaziken – Counter + Focus Blast

Strategy Tip: Use fast-charging Fighting-types to quickly burn through Giovanni’s shields in the early phase.

Round 2 Options

🪨 Shadow Rhyperior (Ground/Rock)

A tanky and powerful Shadow Pokémon, weak to Water and Grass.

Top Counters:

• Mega Swampert – Water Gun + Hydro Cannon

• Primal Kyogre – Waterfall + Origin Pulse

• Mega Sceptile – Bullet Seed + Frenzy Plant

• Mega Blastoise – Water Gun + Hydro Cannon

☠️ Shadow Nidoking (Poison/Ground)

Versatile and dangerous, but weak to Water, Ground, Ice, and Psychic.

Top Counters:

• Primal Kyogre – Waterfall + Origin Pulse

• Shadow Mewtwo – Psycho Cut + Psystrike

• Mega Garchomp – Mud Shot + Earth Power

🦘 Shadow Kangaskhan (Normal)

A heavy-hitting Normal-type with versatile movesets.

Top Counters:

• Mega Lucario – Counter + Aura Sphere

• Mega Heracross – Counter + Close Combat

• Mega Blaziken – Counter + Focus Blast

• Mega Rayquaza – Dragon Tail + Dragon Ascent

Strategy Tip: Build your second team slot around your best Fighting or Ground-type attacker to cover all potential second-phase options.

Round 3: Shadow Dialga (Steel/Dragon)

Dialga is the true end-boss in June 2025. It resists many common move types and hits incredibly hard.

Top Counters:

• Mega Lucario – Counter + Aura Sphere

• Primal Groudon – Mud Shot + Earthquake

• Mega Garchomp – Mud Shot + Earth Power

• Shadow Excadrill – Mud-Slap + Scorching Sands

• Mega Heracross – Counter + Upper Hand

Strategy Tip: Use Ground-type Pokémon to exploit Dialga’s Steel typing. Consider saving your shield(s) for this round unless you’re heavily outmatched earlier.

⚙️ Team Build Recommendation

To effectively counter Giovanni’s full team, try this versatile build:

1. Lead: Mega Lucario (Fighting coverage + shield baiting)

2. Middle: Mega Swampert or Primal Kyogre (Handles Rhyperior/Nidoking)

3. Closer: Primal Groudon or Mega Garchomp (Counter Dialga with strong Ground-type moves)

This setup gives strong type coverage across all potential matchups, along with shield control and fast energy generation.
