Qwilfish is a Water / Poison-type Pokémon, No. 211 in the National Pokédex, introduced in Generation 2 (Johto region).
« Fishers detest this troublesome Pokémon because it sprays poison from its spines, getting it everywhere. A different form of Qwilfish lives in other regions. »
Qwilfish is a round sea Pokémon covered in sharp spikes, with a flat, paddle-shaped tail. Its upper half is dark teal and its lower half light greenish-yellow.
To attack, it drinks over ten litres of water and shoots poisonous quills. The Hisuian form evolves into Overqwil; the Johtonian form cannot evolve.
In the series, Harrison sends a Qwilfish against Misty and her Corsola at the Whirl Cup, where it is quickly beaten.
It is based on the pufferfish or porcupinefish, which inflate and are covered in spines. Qwilfish may come from quill and fish.
