While most trainers evolve Qwilfish into Overqwil immediately, the unevolved form has a niche with Eviolite boosting its defenses. Only weak to Electric, Ground, and Psychic. Introduced in Gen 2. Sits at a decent but contested Speed tier.
Attack and Defense carry most of Qwilfish's stat budget. Sp. Atk's the obvious dump stat. Tough to catch and yields 1 Attack EV. Follows a medium-fast 1M XP curve.
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 Weakness
GoodQwilfish's Water/Poison typing leaves it vulnerable to Electric, Ground, and Psychic moves. With 8 resistances, the defensive profile is strong. Qwilfish's physical bulk (base 85 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
Qwilfish doesn't evolve by leveling. You'll need an evolution item to push it forward to Overqwil. The evolved forms gain up to 70 total stats over Qwilfish.
How to Evolve
Breed Qwilfish easily with 10 breeding partners from the Water2 egg group.
Toxic Spikes is the priority every time Qwilfish comes in. Impish nature and max HP and Defense EVs keep it alive long enough to get layers down, while Leftovers provides passive recovery each turn. Intimidate rounds it out.

A solid spread overall. Qwilfish gets Aqua Tail and Sludge Bomb for same-type damage alongside Bug and Dark coverage and more. It won't blow anyone away, but it doesn't leave you stuck either.
