Mid-stage Pokemon like Poliwhirl rarely see competitive play outside of special formats. It's a waypoint on the road to Poliwrath, which is where the real potential kicks in. An original Gen 1 pick. Sits at a decent but contested Speed tier.

Speed and HP carry most of Poliwhirl's stat budget. Sp. Atk's the obvious dump stat. Common in the wild and yields 2 Speed EVs. Follows a 1.06M XP medium-slow curve.

Poliwhirl Weakness

Good

Electric and Grass-type moves hit Poliwhirl for super-effective damage. 4 resistances help offset the weaknesses. Just 2 weak spots to worry about, which keeps teambuilding straightforward.

    or evolve from Poliwag (Step 1)
  • Poliwhirl is meant to evolve into Poliwrath. At 385 BST, the stats aren't there for competitive play yet. Pre-evolution Pokemon rarely hold up against fully evolved threats.

  • Watch for Raikou (Electric) and Venusaur (Grass) when using Poliwhirl. They all hit it super-effectively with STAB. Only 2 weaknesses means fewer dedicated counters to worry about.

  • Poliwag evolves into Poliwhirl at level 25. Poliwhirl can evolve into Poliwrath and Politoed depending on the method. Poliwhirl is a middle-stage evolution in the Poliwag line.

  • Base 90 Speed is workable — faster than some, slower than many. On offense, Poliwhirl is a physical attacker with base 65 Attack.

  • Poliwhirl appears in 20 games, including Yellow, Red & Blue, and Gold & Silver.

One of the original 151, Poliwhirl has appeared in 20 games — nearly every mainline game. From Red & Blue through the latest titles, it's rarely been left out of a regional Pokedex.
