Qwilfish is a sea dwellingpiscinePokémon with a spherical body and a flat, paddle-shaped tail. The upper half of its body is dark teal and the lower half is very light yellow. Its tail is tall and thin with a dark teal outline, light yellow inside, and two dark teal dots in the center that resemble the Japanese 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 of water to inflate its body. It then uses the water pressure to shoot poisonous quills at its foe, which can cause fainting. Due to its round body, Qwilfish is not a great swimmer, and when filled with water it is even harder for it to swim.
In Hisui, Qwilfish has a different appearance from its Johtonian counterpart due to its diet. The lower half is colored light yellow while the upper half is black with black spikes that has dark purple tips. The front spikes on their forehead are smaller. There are crescent purple lines underneath Qwilfish's eyes and its lips are colored purple. It now has a large, flat tail with a black outline and a purple inside, which also has a pattern that resembles the letter "q."
Hisuian Qwilfish is despised by the fisherman of that region, due to their poison wreaking havoc on the humans trying to fish in the seas it lives in.
Qwilfish, the Balloon Pokémon. The quills covering the entire body have evolved from scales. A Qwilfish can cause its body to swell in order to shoot its needles in all directions.
A swarm of Qwilfish appeared in Querulous Qwilfish, where they were angered by pollution that occurred as a result of an accident that occurred during the construction of the Battle Tower. Crystal captured all of them with her skills. Afterwards, she found a baby Qwilfish stuck in the toxic waste; as she prepared to take it to a Pokémon Center, Suicune appeared, healing Qwilfish and purifying the seawater. It is unknown if the Qwilfish are still under Crystal's ownership or were released afterwards.
In order to attack the enemy all over the body with its poisonous sting, the Qwilfish has to take in a lot of water and expand up to several times of its actual size.*
Qwilfish sucks in water, inflating itself. This Pokémon uses the pressure of the water it swallowed to shoot toxic quills all at once from all over its body. It finds swimming somewhat challenging.

Hisuian Qwilfish
Hisuian Qwilfish has the same base stats as Johtonian Qwilfish. Due to the different way stats are calculated in Pokémon Legends: Arceus, exact minimum and maximum stats are not shown in this table.
Qwilfish swallows gallons of seawater to inflate itself to intimidate enemies. If it gets startled, it spits out all that water and sends itself flying to who knows where.
Qwilfish seems to be based on pufferfish or porcupinefish, which inflate their bodies when threatened and are covered in spines. Many species are incredibly toxic when ingested, which explains Qwilfish's Poison type. However, its ability to directly inject venom through its spines is similar to a lionfish. It is also reminiscent of a naval mine due to its round body and ability to explode.
Name origin
Qwilfish may be a combination of quill and fish.
Harysen may be derived from 針千本 harisenbon (porcupinefish). The character 千 sen in 針千本 harisenbon means thousand, and this numerical theming is continued with Overqwil's Japanese name.
