Qwilfish

**Qwilfish** (Japanese: **ハリーセン** *Harīsen*) is a Water/Poison-type Pokémon introduced in Generation II.

It has a Dark/Poison-type Hisuian form introduced in Generation VIII.

## Biology

### Physiology

#### Johtonian

Qwilfish resembles a pufferfish. It has a teal-green top and a pale green underside. Noticeable features of Qwilfish are its toxic spikes, its paddle-like tail, and its round shape. Its eyes are straight and serious.

#### Hisuian

Qwilfish has similar look to its Johto 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."

### Behavior

#### Johtonian

To defend themselves, Qwilfish quickly swallow large amounts of water (2.6 gallons/approx. 10 litres on average) and inflate themselves to up to twice their original sizes, hoping to match their foes in stature. In this state, they can launch the spikes off of their bodies to spear and inject enemies with their toxins. While inflated, however, Qwilfish experience much trouble swimming; though they are already not very good swimmers when deflated, they often will fail to move at all when fully inflated, simply floating along in the ocean currents until they expel all of their water.

Qwilfish are territorial and will engage in inflation contests to see who can grow the largest. Generally, individuals float away in currents before winners can be determined. They usually swim in the open ocean, far away from the shore.

#### Hisuian

In the cold waters of Hisui (and by extension Sinnoh), resources were scarcer than in more temperate regions. Scientists believe that the region's harsher climate forced Hisuian Qwilfish to become more aggressive than their relatives in order to survive. Rather than inflating themselves for protection, they instead spray venom from the tips of their barbs, jetting it through the water in streams. In addition to being noxious, this venom numbs upon contact and can even paralyze nerves if left untreated. Hisuian Qwilfish are short-tempered and will consider any foreign entity that approach them to be a threat. Sinnohan fishermen historically were at odds with these Pokémon; there are many recorded accounts of fishing boats returning from the sea with full hauls, only to have them spoiled by a Hisuian Qwilfish spraying venom all over the catches. Nets were also commonly torn to shreds by their spiky exteriors. Their relationships with these fishermen weren't strictly detrimental, however. Hisuian Qwilfish venom, after being diluted with seawater, was also used as an anesthetic for emergency medical treatments on ships.

### Natural abilities

By inflating themselves, Qwilfish can eject their spikes to poison their victims.

Hisuian Qwilfish can can use their barbs to shoot venom on their prey, leaving their victims' nerves numbed and paralyzed.

## Evolution

Qwilfish does not evolve. However its Hisuian form can evolve into Overqwil after using Strong Style Poison Barrage for 20 times.
