Psychic moves don't affect Overqwil at all — that's the advantage of Dark/Poison typing. Intimidate lowers the opponent's Attack on switch-in. Known as the Pin Cluster Pokemon. Introduced in Gen 8.
Attack and Defense carry most of Overqwil's stat budget. Sp. Atk's the obvious dump stat. Tough to catch and yields 2 Attack EVs. Follows a medium-fast 1M XP curve.
Its lancelike spikes and savage temperament have earned it the nickname “sea fiend.” It slurps up poison to nourish itself.
Overqwil Weakness
ExcellentOverqwil is weak to Ground-type moves. On the flip side, it's immune to Psychic-type moves entirely. 4 resistances help offset the weaknesses. Overqwil's physical bulk (base 95 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
Getting Overqwil requires an evolution item, not just grinding levels. The chain starts at Qwilfish. Breed this form to get Qwilfish eggs (average hatch time). HP grew the most through evolution (+20 over Qwilfish), and Overqwil peaks at 510 total stats.

Intimidate changes the entire equation for Overqwil. The 510 BST doesn't tell the full story. Ranked C-Tier as a wallbreaker.
Overqwil's biggest threats include Excadrill (Ground), all carrying super-effective STAB moves. Only 1 weakness means fewer dedicated counters to worry about.
