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. Special's the obvious dump stat. Common in the wild and yields 2 Speed stat exp. Follows a 1.06M XP medium-slow curve.
Under attack, it uses its belly spiral to put the foe to sleep. It then makes its escape.
Poliwhirl Weakness
AvgElectric and Grass-type moves hit Poliwhirl for super-effective damage. Few weaknesses and 3 resistances make the typing clean. Just 2 weak spots to worry about, which keeps teambuilding straightforward.
- Only 15 types exist — Dark, Steel, and Fairy are absent
- Ghost has no effect on Psychic (a known bug, fixed in Gen II)
- Special stat governs both offense and defense — no Sp.Atk / Sp.Def split
Partway through Poliwag's chain, Poliwhirl is a Water type pushing toward Politoed. No breeding at this stage. So far, HP got the biggest boost (+25 from Poliwag). The final form adds another 125 stats on top.
