How to Evolve Hisuian Qwilfish in Pokémon GO

Hisuian Pokémon bring a unique flavor to Pokémon GO, with their regional forms and special evolution conditions. One standout among them is Hisuian Qwilfish, a Dark and Poison-type variant introduced through limited-time events and research tasks. But unlike standard evolutions, evolving Hisuian Qwilfish into Overqwil involves more than just candy.

If you’re wondering how to evolve Hisuian Qwilfish in Pokémon GO, this complete guide breaks down everything—from where to find it, how to earn Qwilfish Candy, and what special tasks you need to complete to unlock its powerful evolution.

Let’s get started!


🐡 What Is Hisuian Qwilfish in Pokémon GO?

Hisuian Qwilfish is a regional variant of the classic Qwilfish, first seen in the Hisui region (from Pokémon Legends: Arceus). In Pokémon GO, it’s a Dark/Poison-type Pokémon with a fearsome design and spiky exterior, making it both visually striking and battle-ready.

Key Stats:

  • Type: Dark / Poison
  • Max CP: ~2650 (at Level 50)
  • Strong Against: Grass, Fairy, Psychic
  • Weak Against: Ground-type attacks

Hisuian Qwilfish has been featured during events like the Hisui Celebration and sometimes pops up in:

  • Wild encounters (during themed events)
  • 7km Eggs (rare cases)
  • Field Research Tasks

It isn’t always available, so catching one while it’s active is crucial.


🔁 Hisuian Qwilfish Evolution: Overqwil

Once you’ve caught Hisuian Qwilfish, your next goal is to evolve it into Overqwil, a strong, intimidating Pokémon that stands out on any team.

Overqwil, also a Dark/Poison-type, maintains the same type synergy but gains more power and better usability in PvP and PvE formats.

Evolution Requirements:

  • 50 Qwilfish Candy
  • Win 10 Raids with Hisuian Qwilfish as your Buddy

⚠️ Event Tip: During certain events (e.g. Timed Research or GO Tour), the raid requirement may temporarily reduce to 1 raid win, so always check in-game announcements!


🎯 Step-by-Step Guide to Evolve Hisuian Qwilfish in Pokémon GO

Let’s break down each part of the evolution process so you can evolve your Hisuian Qwilfish into Overqwil with ease.


Step 1: Catch a Hisuian Qwilfish

Before evolving, you’ll obviously need to catch or obtain a Hisuian Qwilfish.

How to Get Hisuian Qwilfish:

  • Event Spawns: Keep an eye on event announcements like “Hisui Week,” “Legends Arceus Celebration,” or “GO Fest.” These events often feature regional forms.
  • Field Research Tasks: Limited-time Research can reward encounters with Hisuian Qwilfish.
  • 7km Eggs: Occasionally, it hatches from these eggs during special events.
  • Trade: If you’re lucky, a friend might trade you one (but it won’t help with buddy tasks).

📝 Pro Tip: Turn on push notifications for events or follow official Pokémon GO channels to avoid missing rare spawns.


Step 2: Collect 50 Qwilfish Candy

The next major requirement is 50 Candy. You can earn Qwilfish Candy through multiple methods:

Methods to Collect Candy:

  • Catch Wild Qwilfish (normal or Hisuian form)
  • Use Pinap Berries while catching for double candy
  • Walk Hisuian Qwilfish as your Buddy (1 candy per 3km)
  • Transfer extra Qwilfish
  • Use Rare Candies (convert into Qwilfish Candy)

🍬 Candy Tip: Set your Hisuian Qwilfish as a buddy early to passively gather candy while working on the raid requirement too.


Step 3: Set Hisuian Qwilfish as Your Buddy

To proceed with the evolution, Hisuian Qwilfish must be your active Buddy. This is crucial for meeting the raid-related evolution condition.

How to Set Buddy:

  1. Tap your Trainer avatar
  2. Select Buddy
  3. Tap “Swap Buddy”
  4. Choose Hisuian Qwilfish

Once set, you’ll see it walking alongside your avatar on the map.


Step 4: Win 10 Raids with Hisuian Qwilfish as Buddy

This is the key requirement that sets this evolution apart from traditional ones. You must win 10 raids with Hisuian Qwilfish as your active buddy.

🛡️ Important Notes:

  • Hisuian Qwilfish does NOT need to participate in the battle.
  • It must only be your active Buddy at the time the raid is completed.
  • You can win any type of raid: Tier 1, 3, 5, or Mega.
  • Remote Raids also count.

💡 Event Variation: Occasionally, this number is temporarily reduced to 1 Raid Win during special events. Always double-check event bonuses before grinding 10 raids.

Quick Ways to Complete Raids:

  • Use Free Daily Passes for Tier 1 or 3 raids at local gyms.
  • Join Remote Raids via online communities like:
    • Poké Genie
    • Pokémon GO Discord servers
  • Coordinate with friends for quick, easy raids.

Step 5: Evolve to Overqwil

Once you’ve:

  • Earned 50 Qwilfish Candy
  • Completed 10 raid wins with Hisuian Qwilfish as Buddy

You’ll now see the Evolve button become active on your Hisuian Qwilfish’s summary screen.

Final Steps:

  1. Tap on your Hisuian Qwilfish
  2. Open the summary page
  3. Tap the green “Evolve” button
  4. Confirm the evolution

🎉 Congratulations! You now have Overqwil in your Pokédex and ready for battle!
