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.

It shoots the poison spines on its body in all directions. Its round form makes it a poor swimmer.

Qwilfish Weakness

Good

Qwilfish's Water/Poison typing leaves it vulnerable to Electric, Ground, and Psychic moves. With 7 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.

One boost from Swords Dance and Qwilfish gets dangerous fast. The Adamant nature targets max Attack and Speed, and Swiftswim backs the whole approach. Waterfall and Normal coverage handle most of what's left standing.

You'll want to breed for Astonish and Bubble Beam on Qwilfish. These egg moves aren't just nice to have. Combined with STAB from Hydro Pump and Aqua Tail, they expand what Qwilfish can actually threaten in practice.

  • Qwilfish is meant to evolve into Overqwil. At 440 BST, the stats aren't there for competitive play yet. Pre-evolution Pokemon rarely hold up against fully evolved threats.

  • Watch for Raikou (Electric), Golem (Ground), and Alakazam (Psychic) when using Qwilfish. They all hit it super-effectively with STAB.

  • Qwilfish evolves into Overqwil using a Barb Barrage 20 Times In Strong Style. Qwilfish is the base form of this evolutionary line.

  • Intimidate is what you want on Qwilfish. Every competitive set worth running is built with that ability in mind. The alternatives (Poison Point, Swift Swim) work on paper but Intimidate is what makes Qwilfish worth using.

  • Base 85 Speed is workable — faster than some, slower than many. On offense, Qwilfish is a physical attacker with base 95 Attack. Defensively? Enough bulk to take a hit or two.

  • Qwilfish appears in 19 games, including Gold & Silver, Crystal, and Ruby & Sapphire.

Since debuting in Gold & Silver, Qwilfish has appeared in 19 titles over 8 generations. Along the way, it received a Hisuian form in Generation 8, keeping it relevant across different competitive metas.
