Quick Links
Water/Poison-type Qwilfish first appeared in the waters of the Johto region inPokemon Gold/Silver. At the time of its debut, this Balloon Pokemon was incapable of evolving. It wasn’t until Gen 8 inPokemon Legends: Arceuswhere Qwilfish was given a regional variantandan evolution.
Hisuian Qwilfish discards its Water-typing for Dark, becoming a dual-type Dark/Poison Pokemon. Unlike regular/Johtonian Qwiflish, Hisuian Qwilfish evolves into Overqwil via a unique evolution method. Now thatPokemon Scarlet & Violetis compatible withPokemon HOME, trainers can now have a Hisuian Qwilfish and Overqwil in their party.
Updated on June 26, 2025 by Renri Seong:Before the release of part 2 ofPokemon Scarlet & Violet’s expansion pass, Hisuian Qwilfish and its evolution Overqwil were only obtainable through transfer or trade. With the Indigo Disk DLC, you can visit Terarium, which is swarming with familiar Pokemon from past generations. Those that look to the colder biomes of Terarium may find the Dark/Poison-type Hisuian Qwilfish. InPokemon Legends: Arceus, Hisuian Qwilfish could evolve into Overqwil, something that the original/Johto Qwilfish is incapable of doing. The following guide has been updated to include information about the Indigo Disk and how you can get and evolve Hisuian Qwilfish without trade or transfer.
Where to Find Hisuian Qwilfish in Indigo Disk
Polar Biome in Terarium
If you purchased the expansion pass forPokemon Scarlet & Violet, you will gain access to the Indigo Diskafteryou have completed the following:
You can go to Terarium/Blueberry Academybeforecompleting “The Way Home,” the last story quest inPokemon Scarlet/Violet’s base game. However, you’ll be prevented from advancing Indigo Disk’s story after your first class in Terarium at the Coastal Biome. Once you complete “The Way Home,“the rest of Indigo Disk’s story will be unlocked.
Once you’re in Terarium, you’ll want to head towards thePolar Biome. You can find Hisuian Qwilfish swimming around in the water. Since it can be a bit difficult sneaking up on Pokemon while swimming, you may have better luck just battling the Hisuian Qwilfish head-on. The Hisuian Qwilfish levels will be around mid-50s to mid-60s.
How to Get Hisuian Qwilfish without Indigo Disk DLC
Trading or Transferring
While the Water/Poison-type Qwilfish can be found in the oceans of Paldea,Hisuian Qwilfish isn’t as lucky. Players will need totransfer Hisuian Qwilfishfrom eitherLegends: ArceusorPokemon GOto obtain it inScarlet/Violet. Transferring is done throughPokemon HOME, a free app with subscription features for mobile devices and Switch.
To get Hisuian Qwilfish, players will need to have access to theCobalt CoastlandsinLegends: Arceus. They will also need to have unlocked theRide Basculegion.
Hisuian Qwilfish spawns in the following sub-areas:
Since it can be difficult to catch Pokemon in the water, players may want to try and get a back strike from a distance using Feather/Wing/Jet Balls. Items such as Mud Balls or Sticky Globs can be used to stun the Qwilfish if they turn aggressive. Otherwise, trainers can catch them the old-fashioned way: Battling it with one of their Pokemon.
Getting Hisuian Qwilfish in Pokemon GO
If trainers are catching Hisuian Qwilfish inPokemon GO, they can get it from a wild encounter. 7km Eggs, which are earned from opening Gifts from friends, also have a chance of hatching into a Hisuian Qwilfish. They’re in the Uncommon Tier, meaning they’ll have to contend with other Pokemon in the hatch pool, making thisa somewhat unreliable method of getting it. Thus, players are better off catching Hisuian Qwilfish in the wild. It tends to appear more in grim areas or during certain in-game events.
How to Evolve Hisuian Qwilfish
How to Get Overqwil
Before transferring Hisuian Qwilfish, trainers will want to evolve it. Hisuian Qwilfish evolves into Overqwil by using the moveBarb Barrage20x in theStrong Style. This is a Poison-type physical move that Hisuian Qwilfish learns atlevel 15 inLegends: Arceusorlevel 28 inScarlet/Violet.
Because Strong/Agile-style moves do not exist inScarlet/Violet, you can eitherevolve Hisuian Qwilfish in Legends: Arceus. However, the less-tedious method is to evolve Hisuian Qwilfish inScarlet/Violetbyleveling it up while it knows the move Barb Barrage.
If you want to catch Overqwil, you can find it in6-star Tera Raids. The 6-star Raids unlock once you’ve completed theAcademy Ace Tournament, and have cleared some of the 5-star Tera Raids around Paldea and Kitakami. You’ll eventually receive a call fromJacqaboutblack Tera Raid crystals.
Is Overqwil Good?
Strengths & Weaknesses
Dark/Poison is already a unique type combination, but those looking for a speedy special attacker won’t find that in Overqwil. It’s primarily a physical attacker with moderate Speed. Here’s what trainers are looking at:
85
115
65
95
510
Psychic
Poison Point:
Overqwil has a 30% chance of poisoning opponents that make physical contact with it.
Intimidate (Hidden):
Lowers the opposing Pokemon’s attack stat when Overqwil enters battle.
One advantage Overqwil has inScarlet/Violetcompared toLegends: Arceusis its Abilities. When transferred, Overqwil can havePoison Point or Swift Swim. If players choose to use an Ability Patch on it, they can get Overqwil’s Hidden Ability: Intimidate.
Speed
Special Attack
While Special Defense and Special Attack are Overqwil’s worst stats, players don’t want it to suffer a bane in Special Defense. Instead, they’ll want a Nature that has a bane in Special Attack. This is due to Overqwil’s moveset and arguably stronger moves being primarily physical attacks. Trainers can also use TMs to give it some more coverage.
