'''Qwilfish''' ([[List of Japanese Pokémon names|Japanese]]: '''ハリーセン''' ''Harysen'') is a dual-type {{2t|Water|Poison}} {{OBP|Pokémon|species}} introduced in [[Generation II]].

In [[Hisui]], Qwilfish has a dual-type {{2t|Dark|Poison}} [[regional form]], '''{{rf|Hisuian}} Qwilfish'''. Hisuian Qwilfish evolves into {{p|Overqwil}} after using [[Strong style|Strong Style]] {{m|Barb Barrage}} 20 times. In the modern day, Hisuian Qwilfish can be found in [[Blueberry Academy]]'s [[Terarium]].

[[Johto]]nian Qwilfish is not known to evolve into or from any other Pokémon.

(Specifics may differ in past games. Refer to [[#Evolution data|Game data→Evolution data]] for these details.)

==Biology==
[[File:QwilfishShiningLegends21.jpg|thumb|150px|left|Qwilfish inflating its body]]
Qwilfish is a {{DL|List of Pokémon by habitat|Sea Pokémon|sea dwelling}} {{wp|fish|piscine}} {{OBP|Pokémon|species}} with a spherical body and a flat, paddle-shaped tail. The upper half of its body is dark teal and the lower half is light greenish-yellow. Its tail is tall and thin with a dark teal outline, light greenish-yellow inside, and two dark teal dots in the center that resemble the katakana character ハ ''Ha''. Its eyes are even with its body and are always seen slanted angrily. Below its eyes are its puffy pink lips. All around its body are sharp, conical spikes, which evolved from scales over time.

In order to attack, Qwilfish drinks over 2.6 gallons (10 litres) of water to inflate its body. It then uses the water pressure to shoot poisonous quills at its foe, which can cause fainting. Qwilfish is briefly left defenseless shortly after firing its quills; this is believed by some expert fishers to be the opportune moment to catch this Pokémon. Due to its round body, Qwilfish is not a great swimmer, and when filled with water it is even harder for it to swim. When Qwilfish faces a larger opponent, it will inflate its body to match its size as close as it can. If it is startled while inflated, it will spit out all its water, propelling itself away.

Qwilfish, Hisuian Qwilfish, and the latter's evolved form, {{p|Overqwil}}, are the [[signature move|only known Pokémon]] capable of learning the move {{m|Barb Barrage}}.

===Forms===
Qwilfish has a [[regional form]]: {{rf|Hisuian}} Qwilfish.

In [[Hisui]], its upper half is black, while its lower half is pale yellow. Its body is covered in spikes; the spikes on its upper body have dark purple tips, except for the two spikes on its forehead, which are also smaller in size. Hisuian Qwilfish can spray poison from these spines. There are crescent purple lines underneath Hisuian Qwilfish's eyes, and its lips are also colored purple. Its flat tail has a black outline with a light yellow inside, and a black pattern that resembles the lowercase letter "q".

Hisuian Qwilfish is despised by the fishermen of the Hisui region, due to its poison wreaking havoc in the seas it lives in. Its poisonous spikes are thicker and shorter than Qwilfish from other regions. Getting jabbed by Hisuian Qwilfish's poison will make a person feel pain and misery for three days and three nights. This form of Qwilfish absorbs poison from the food it consumes such as toxic minerals. The purple coloration on its body serves as evidence of its potent poison. In the present day, Hisuian Qwilfish and its Evolution are known to be found offshore in cold parts of the world and in Blueberry Academy, located somewhere in [[Unova]]'s ocean, specifically in the [[Terarium]]'s [[Polar Biome]]. It has also been seen inside [[Hyperspace Lumiose]].

===Evolution===
[[Hisuian form|Hisuian]] Qwilfish evolves into {{p|Overqwil}}. Johtonian Qwilfish cannot evolve.

==Trivia==
* Qwilfish shares its {{pkmn|category}} with {{p|Igglybuff}}, {{p|Jigglypuff}}, {{p|Wigglytuff}}, and {{p|Drifloon}}. They are all known as the Balloon Pokémon.
* Qwilfish can be seen as a parallel to {{p|Remoraid}}. Both of them are {{type|Water}} {{cat|Generation II Pokémon}}. Qwilfish is exclusive to {{game3|FireRed and LeafGreen|FireRed|s}}, while Remoraid is exclusive to {{game3|FireRed and LeafGreen|LeafGreen|s}}, with both Pokémon found in the same locations in their respective versions, and both being swarm Pokémon in [[Generation II]] and {{game|HeartGold and SoulSilver|s}}.
* A [[Media:Capsule Monsters Papyo.jpg|pre-alpha sketch]] of an [[List of unused Pokémon and character designs|unused Pokémon]] depicts a Pokémon with the same Pokédex number as Qwilfish.
* Qwilfish and {{p|Overqwil|its Hisuian evolved form}} are the only {{type|Poison}} {{DL|List of Pokémon by shape|Pokémon with fins}}, and the only Poison-type Pokémon in the {{egg3|Water 2}}.
* According to several {{tc|Team Plasma Grunt}}s, [[Hugh]]'s hairstyle resembles a Qwilfish.
* Hisuian Qwilfish and its evolved form were first hinted in {{g|Brilliant Diamond and Shining Pearl}} before their official reveal in {{g|Legends: Arceus}}, where they were mentioned in a [[Sinnoh myths#The Sea's Legend|book]] in the [[Canalave Library]] where Overqwil is referred to as "a Qwilfish with huge spikes".
* Hisuian Qwilfish is the first [[Hisuian form]] that can be caught outside of [[Hisui]] (excluding [[Poké Portal News]] event [[Tera Raid Battle]]s).
** Hisuian Qwilfish and {{rf|Galarian}} {{p|Slowpoke}} are the only [[Regional form]]s that can be caught in all [[Generation IX]] games (excluding [[Poké Portal News]] event [[Mass outbreak]]s).
* Qwilfish is the only Pokémon with a name beginning with the letter "Q" that is not followed by a "U" like most words in the English language.
**It is also one of only two Pokémon to have a "Q" in its name that is not followed by a "U", the other being its {{rf|Hisuian}} evolved form Overqwil.
* Hisuian Qwilfish and its evolved form are the only dual-type {{2t|Poison|Dark}} Pokémon to have Dark as their primary type instead of their secondary type.
* The [[Pokémon Gold and Silver Spaceworld '97 demo]] has an early design of Qwilfish named プクー ''Pukū'', whose name may be a corruption of 河豚 ''{{wp|fugu}}'' ({{wp|pufferfish}}). It was a pure Water type and would evolve into シビレフグ ''Shibirefugu'' at level 18.

===Origin===
Qwilfish seems to be based on {{wp|Tetraodontidae|pufferfish}} or {{wp|porcupinefish}}, which inflate their bodies when threatened and are covered in {{wp|spine}}s. Many species are incredibly toxic when ingested, which explains Qwilfish's {{t|Poison}} type. However, its ability to directly inject venom through its spines is similar to a {{wp|lionfish}}. It is also reminiscent of a {{wp|naval mine}} due to its round body and ability to explode.

Hisuian Qwilfish's {{t|Dark}} type and poisonous diet may be based on the illegalisation of the {{wp|fugu}} dish due to its toxicity. The law was put in place a few times in Japanese history, including the 1800s (which {{g|Legends: Arceus}} [[Pokémon world in relation to the real world#Sinnoh|appears to be based on]]), but the illegal fugu market continued and thrived for so long that the governing {{wp|shogun}}ate became incapable of enforcing the law. Hisuian Qwilfish and Overqwil appear to be rarer in recent times, which could be a reference to porcupinefish being threatened due to overfishing for the fugu dish.

====Name origin====
Qwilfish may be a combination of ''[[Wiktionary:quill#English|quill]]'' (the noun, meaning porcupine or hedgehog spikes, or the verb, meaning to pierce with quills) and ''{{wp|fish}}''.

Harysen may be derived from [[Wiktionary:針千本|針千本]] ''harisenbon'' ({{wp|porcupinefish}}). The Japanese name for porcupinefish, 針千本 (''harisenbon''), can be interpreted literally as "one thousand sewing needles".

'''Overqwil''' ([[List of Japanese Pokémon names|Japanese]]: '''ハリーマン''' ''Haryman'') is a dual-type {{2t|Dark|Poison}} {{OBP|Pokémon|species}} introduced during [[Generation VIII]], in {{g|Legends: Arceus}}.

It evolves from {{rf|Hisuian}} {{p|Qwilfish}} after using [[Strong style|Strong Style]] {{m|Barb Barrage}} 20 times.

(Specifics may differ in past games. Refer to [[#Evolution data|Game data→Evolution data]] for these details.)

==Biology==
Overqwil is a large, spherical {{wp|fish|piscine}} {{OBP|Pokémon|species}} that resides in the sea. All over its body are overgrown conical spikes whose colors correspond to those on Overqwil's body. Its top half is black while its bottom half is light yellow; the two halves meet in the middle and form a wave pattern. The spikes on the top half of its body have parts of purple at their tips, and two very long spikes at the top and bottom of its body jut out in a straight direction. Above its eyes and around part of the top half of its body, Overqwil has circular purple dots. Its lips also have a purple coloration and appear puffy, and its small light-yellow eyes have purple pupils and are always fixated on an annoyed expression. In between its eyes are two pairs of spikes, the outer ones being longer and resembling eyebrows. Its large tail appears flat with a black outline and a purple inside, which also has a pattern that resembles the letter "Q."

Overqwil has a very aggressive personality to match its short temper, which has given it the nickname "sea fiend." Its diet consists of poison. Overqwil's poisonous spikes react automatically to targets, even while asleep. The barbed spikes will stab any moving thing that approaches Overqwil, and have been known to adhere tightly to their target. It has been recently seen along with its pre-Evolution offshore in cold parts of the world, specifically in the [[Terarium]]'s [[Polar Biome]]. It has also been seen inside [[Hyperspace Lumiose]].

Overqwil and its pre-evolved form, {{rf|Hisuian}} {{p|Qwilfish}}, are the [[signature move|only known Pokémon]] capable of learning the move {{m|Barb Barrage}}.

===Evolution===
Overqwil evolves from {{rf|Hisuian}} {{p|Qwilfish}}.

==In the TCG==
{{main|Overqwil (TCG)}}

==Trivia==
* Overqwil was first hinted at in {{g|Brilliant Diamond and Shining Pearl}} before its official reveal in {{g|Legends: Arceus}}, being alluded to in a [[Sinnoh myths#The Sea's Legend|book]] in the [[Canalave Library]], where it is referred to as "a Qwilfish with huge spikes".
* Overqwil and Qwilfish are the only {{type|Poison}} {{DL|List of Pokémon by shape|Pokémon with fins}} and the only Poison-type Pokémon in the {{egg3|Water 2}}.
* In [[Generation IX]], prior to the Version 2.0.1 update of {{g|Scarlet and Violet}}, Overqwil was unable to learn {{m|Water Pulse}}, {{m|Acid Spray}}, {{m|Hex}}, and {{m|Swift}} via [[TM]], while its pre-evolved form could.
* Overqwil is one of only two Pokémon to have a "Q" in its name that is not followed by a "U" (unlike most words in the English language with a "Q" in it) with the other being its pre-Evolution Qwilfish.
* Overqwil and its pre-evolved form are the only dual-type {{2t|Dark|Poison}} Pokémon to have Dark as their primary type instead of their secondary type.

===Origin===
Overqwil appears to be based on {{wp|Tetraodontidae|pufferfish}} or {{wp|porcupinefish}}, which are covered in spines and are poisonous to eat. Its {{t|Dark}} typing and poisonous diet may be based on the illegalisation of the {{wp|fugu}} dish due to its toxicity. The law was put in place a few times in Japanese history, including the 1800s (which {{g|Legends: Arceus}} [[Pokémon world in relation to the real world#Sinnoh|appears to be based on]]), but the illegal fugu market continued and thrived for so long that the governing {{wp|shogun}}ate became incapable of enforcing the law. Hisuian Qwilfish and Overqwil appear to be rarer in recent times, which could be a reference to porcupinefish being threatened due to overfishing for the fugu dish.

Its oversized spikes along with their ability to inject poison may also be inspired by other venomous marine animals such as {{wp|lionfish}} or {{wp|sea urchin}}s. Overqwil and its pre-Evolution's notoriety amongst fishermen may be a reference to the significant threat that lionfish pose as an invasive species in the Atlantic Ocean, another potential inspiration for Overqwil's {{t|Dark}} type.

Overqwil's physical appearance and ability to learn {{m|Self-Destruct}} (and Qwilfish's ability to learn {{m|Explosion}} in many generations) are reminiscent of a {{wp|naval mine}}. It also resembles a {{wp|Morning star (weapon)|morning star}} or the spiked end of a {{wp|Flail (weapon)|flail}}. Based on its Japanese {{pkmn|category}}, it may also be partly inspired by the ''{{wp|kenzan}}'' (剣山, lit. "sword mountain"), a device consisting of a plate with numerous needles or spikes on it, used to fix flowers in place for the art of {{wp|ikebana}} (flower arranging).

====Name origin====
Overqwil may be a combination of ''[[Wiktionary:overkill|overkill]]'' and ''{{p|Qwilfish}}''.

Haryman may be derived from ハリーセン ''Harysen'' (Qwilfish) or [[Wiktionary:針千本|針千本]] ({{wp|porcupinefish}}), with the [[Wiktionary:千#Japanese|千]] ''sen'' (thousand) part replaced with [[Wiktionary:万#Japanese|万]] ''man'' (ten thousand or {{wp|myriad}}). The Japanese name for porcupinefish, 針千本 (''harisenbon''), can be interpreted literally as "one thousand sewing needles". The last character in 針千本 ''harisenbon'', 本, is a counter for slender objects. The Japanese name for Overwqil can be interpreted literally as "ten thousand sewing needles".
