Pidgey

Its evolution into Pidgeotto at level 18 offers a 43% increase in base stats, lagging behind Spearow’s 25% growth per evolution step, making it a slower performer in the mid-game. Pidgey’s access to Fly as an HM move provides map traversal utility unmatched by Ekans or Rattata, but in battle, it fails to knock out even a level 20 Geodude without multiple turns. For trainers who prioritize coverage over power, Pidgey’s balanced growth is a comfort, yet it remains the weakest link in any competitive setup.
