Stuck trying to evolve Hisuian Qwilfish? Discover the hidden buddy requirements, fastest raid strategies, and candy tips to get Overqwil in Pokémon GO.
What Makes Overqwil One of Pokémon GO’s More Unusual Evolutions?
Staring at a greyed-out evolve button for your spiky pufferfish? You aren’t the only trainer stuck on this. For years, veterans caught this Johto classic only to accept it had no evolutionary family. However, the introduction of the Hisui region completely changed the playbook. While the standard version remains a standalone creature, the regional pokemon go hisuian qwilfish features a unique and highly specific evolution path to become the menacing Overqwil.
Evolving this Dark/Poison-type variant takes a lot more than just hoarding candy and hitting a button. It involves a hidden gameplay mechanic tied directly to the Buddy system and Raid Battles. In this comprehensive guide, we will break down exactly how to unlock the evolution button, the fastest methods to clear the requirements without burning through your Premium Raid Passes, and whether Overqwil is actually worth the Stardust for your Great League or Ultra League rosters.
Before You Spend Your Candy, Here’s What You Should Know About the Qwilfish Family
Before you start investing your hard-earned Stardust and time, it is crucial to understand the distinct differences between the two forms of Qwilfish currently available in the game. Many trainers waste time trying to figure out how to evolve the wrong variant!
Why Your Standard Johtonian Qwilfish is Stuck Without an Evolution
The confusion around how do you evolve qwilfish usually stems from the fact that Pokémon GO features two entirely different regional variants of the same species sharing one Pokédex number:
- Johtonian Qwilfish (Standard): This is the original Water/Poison-type Pokémon introduced back in Generation 2. It is typically green and blue. If you are asking how to evolve qwilfish and you have this specific version, the short answer is: you can’t. The standard form does not have an evolution button, and no amount of candy or buddy interactions will change that.
- Hisuian Qwilfish (Regional): Debuting during the Hisuian Discoveries event, this variant is Dark/Poison-type and features a darker, black-and-purple color scheme equipped with sharper spikes. This is the only version that can evolve into Overqwil.
Where Trainers Are Finding Hisuian Qwilfish Right Now
If you want to build an Overqwil, you have to secure the base form first. For trainers tracking down how to get hisuian qwilfish, keep in mind that it relies on specific, rotating methods rather than common everyday wild spawns. If you need to know how do you get hisuian qwilfish in pokemon go to finish your Pokédex, here are the most reliable farming methods:
- 7km Friend Eggs: Historically, Hisuian forms frequently rotate in and out of the 7km egg pool (the yellow and pink eggs you receive from opening gifts sent by friends). Always check the current egg hatch pool at the start of a new season to see if it is currently available.
- Wild Spawns During Events: The Hisuian variant frequently spawns in the wild during specific Sinnoh or Hisui-themed events, such as the Pokémon GO Tour: Sinnoh or the Ultra Unlock: Hisui Celebration.
- Field Research Tasks: Niantic occasionally places the Pokémon in event-exclusive Field Research tasks (e.g., spinning PokéStops for “Catch 10 Pokémon” or “Win a Raid” tasks).
- Trading: If you cannot find one in the wild and the egg pools have rotated, trading with a local friend is the easiest and most guaranteed way to secure your own.
The Hidden Requirement That Stops Most Trainers From Evolving Hisuian Qwilfish
Once you have secured the regional variant in your storage, you will notice that the evolution button is greyed out. Below is the exact qwilfish pokemon go evolution criteria you must meet to trigger it.
The 50-Candy Threshold and the Buddy System Roadblock
To unlock the evolution, you must fulfill two distinct prerequisites simultaneously:
- Gather 50 Qwilfish Candy: You need a stockpile of 50 candies. The good news for your grind is that candy is shared between the standard and Hisuian forms. You can catch, transfer, and use Pinap Berries on the common Johto version to completely fund your Hisuian evolution.
- Win 10 Raids as Your Buddy: This is the hidden roadblock. You must set the specific Hisuian Qwilfish you want to evolve as your active Buddy Pokémon, and then you must win 10 Raid Battles while it is your buddy.
How to Knock Out 10 Raid Wins Without Wasting Premium Passes
Grinding out 10 raids can seem incredibly daunting—and expensive—if you are buying Premium Battle Passes. If you are wondering how do i evolve my qwilfish in pokemon go as a free-to-play trainer, you need a solid strategy. Here are the most efficient ways to knock out the requirement:
- Target 1-Star and 3-Star Raids: Do not worry about gathering a large group for 5-Star Legendary or Mega Raids. 1-Star and 3-Star raids can easily be completed by a solo player. Drop into these lower-tier raids using your free daily Raid Pass to slowly chip away at the requirement over 10 days.
- Utilize Wednesday Raid Hours: Every Wednesday from 6:00 PM to 7:00 PM local time, 5-Star raids take over almost every Gym. If you live in an area with an active local community, you can easily complete 3 to 5 raids in a single hour by following the local raid train.
- Stack Free Passes: You can hold one free daily Raid Pass from the previous day. If you skip raiding on Tuesday, you can hold that pass and do two free raids on Wednesday.
- Raid Days: Niantic frequently hosts 3-hour Raid Days on weekends, usually offering up to 5 additional free Raid Passes from spinning Gym Photo Discs. This is the absolute best time to complete your 10-raid requirement in a single afternoon.
The Buddy Trick That Saves Your Revives and Potions
When tackling the raid requirement, there is one massive community misconception that costs players unnecessary Revives and Potions.
Expert Tip: Your Buddy Qwilfish does not need to participate in the actual raid battle to get credit.
You do not have to put a low-CP, unevolved Pokémon into your raid party and risk losing the battle. The only thing that matters is that the Hisuian Qwilfish is set as your active Buddy on the main map screen when the raid boss is defeated. It doesn’t even need to be fed berries or be physically walking on the map beside your avatar—it just needs to occupy the Buddy slot.
Why Your Evolution Button Might Still Be Locked
Even when seasoned players understand how do you evolve qwilfish in pokemon go, things can still go wrong. If your evolution button remains stubbornly locked, check these common troubleshooting issues.
Common Mistakes Trainers Make With the Buddy Raid Requirement
- You Swapped Buddies Too Early: The raid win only registers at the exact moment the raid boss’s HP hits zero and the “You Win!” animation plays. If you swap your Buddy before the raid fully concludes, it will not count.
- You Are Trying to Evolve a Different Qwilfish: The 10-raid progress is tied to the specific individual Pokémon, not the species as a whole. If you complete 10 raids with one Hisuian Qwilfish as your buddy, you cannot use that progress to evolve a different Hisuian Qwilfish in your storage. You must buddy the exact one you wish to evolve.
- You Lost the Raid: The requirement explicitly states you must win the raid. Simply participating and timing out, or having your whole team faint without beating the boss, does not add to your progress counter.
- You Lack the Candy: Even if the “Win 10 Raids” counter shows 10/10, the button will remain unclickable if you have 49 or fewer Qwilfish candies.
Ready to Evolve: When and How to Finally Trigger the Button
You can evolve your Hisuian Qwilfish the absolute second both conditions (50 candy + 10 raid wins) are met. There is no time-of-day requirement (unlike Eevee into Umbreon or Tyrunt into Tyrantrum), and no weather requirements (unlike Sliggoo into Goodra). Once the drop-down menu on the Pokémon’s stat screen shows the quest is complete, you are free to tap the evolve button at any time.
Is Overqwil Worth Building for PvP or Just a Pokédex Entry?
Putting in the effort to win 10 raids is a significant time investment. Naturally, competitive GO Battle League players want to know: is qwilfish good in pokemon go? Let’s look at the stats.
Analysing Overqwil’s Performance Across the GO Battle League and PvE
Overqwil boasts a fantastic typing of Dark and Poison. This defensive typing is phenomenal because it neutralizes many common weaknesses and leaves Overqwil weak to only one single type: Ground.
- Resistances: Dark, Ghost, Grass, Poison
- Weaknesses: Ground (160%)
For PvE (Raids and Gym attacking), Overqwil is decent but heavily outclassed by top-tier Dark attackers like Tyranitar or Hydreigon, and top-tier Poison attackers like Nihilego. Its maximum CP caps out at 2,946 at Level 40 and 3,330 at Level 50, which just doesn’t offer the raw DPS required for high-level raid solos.
However, in PvP (Trainer Battles), Overqwil shines as a formidable anti-meta pick.
| League | Viability | Best Moveset | Role |
| Great League | Very Good | Poison Jab (Fast) + Aqua Tail / Dark Pulse (Charged) | Fairy counter, shield baiter, safe swap |
| Ultra League | Good | Poison Jab (Fast) + Aqua Tail / Sludge Bomb (Charged) | Cresselia and Fairy-type counter |
| Master League | Poor | N/A | Stats are too low to compete with Legendaries |
Overqwil’s access to Poison Jab makes it a nightmare for popular Fairy-types like Azumarill and Clefable. Its cheap charged move, Aqua Tail, allows it to aggressively bait out opponent shields, while Dark Pulse provides heavy neutral damage and threatens Ghost and Psychic types. If you enjoy climbing the ranks in the GO Battle League, investing the time to evolve a Hisuian Qwilfish with strong PvP IVs (low Attack, high Defense, high HP) is absolutely worth it.
Shiny Hunters: What to Expect From Hisuian Qwilfish
Shiny hunters, rejoice! If you are wondering about shiny hisuian qwilfish pokemon go availability, it is currently live in the game.
The shiny variant made its official debut during the Pokémon GO Tour: Sinnoh event on February 16, 2024. Unlike the dark grey of the standard Hisuian form, the shiny Hisuian Qwilfish features a striking, bright magenta/purple coloration, making it highly coveted. Its evolution, shiny Overqwil, retains this brilliant magenta coloring. Because it is a regional variant, its shiny odds are typically boosted slightly higher than the standard 1/500 rate during dedicated events, though it remains a rare find outside of those focused windows.
Common Questions From the Pokémon GO Community
Q: What is the hardest Pokémon to evolve in Pokémon GO? While winning 10 raids for Hisuian Qwilfish is tedious, it is generally not considered the absolute hardest. That title often goes to Galarian Yamask (which requires winning 10 raids specifically as a buddy, similar to Qwilfish), Galarian Farfetch’d (requires making 10 Excellent Throws as a buddy), or Larvesta (which requires a staggering 400 candy to evolve into Volcarona despite being exceptionally rare in eggs).
Q: How to evolve qwilfish if it is the standard Johto version? You cannot. The standard Water/Poison-type Johto Qwilfish does not have an evolution in Pokémon GO or any mainline Pokémon game. Only the Hisuian form can evolve.
Q: Can I use Premium Battle Passes to evolve it faster? Yes. If you want to evolve your Hisuian Qwilfish in a single day, you can purchase Premium Battle Passes from the in-game shop and do 10 consecutive raids. However, for free-to-play players, simply using your daily free pass over 10 days is the most cost-effective method.
Q: Will progress reset if I swap my buddy to something else? No! Pokémon GO remembers the individual quest progress of each specific Pokémon. If you win 3 raids with Hisuian Qwilfish, swap to a Pikachu for a few days, and then swap back to that exact same Hisuian Qwilfish, it will still show 3/10 raids completed.
Q: Are there any events where the requirement is lowered? Very rarely. Niantic has been known to lower the requirement temporarily during highly specific events. For example, during the Ultra Unlock: Hisui Celebration event in July 2025, the requirement was temporarily reduced from 10 raids down to just 1 raid. However, as soon as the event ended, it reverted to the standard 10 raids. Always check the current season’s event bonuses!
