Bonsly is a baby Pokemon from Gen 4 — it can't hold its own in battle yet. The payoff is Sudowoodo, which is where the real competitive value lives. Worth raising if you need one on your team. 5 type weaknesses to keep in mind.

Bonsly's all-in on Defense at the expense of Sp. Atk. The physical lean is obvious from the bars. Yields 1 Defense EV and follows a medium-fast 1M XP curve.

Its tears elicit sympathy from those who see them, but do not be deceived! This expulsion of body water is merely a physiological mechanism for keeping itself in good health.

Fragile

  • Bonsly isn't fully evolved, so it's not built for competitive play. You'll want to evolve it into Sudowoodo to unlock its full potential. At 290 BST, it's a stepping stone rather than a team anchor.

  • Bonsly's biggest threats include Swampert (Water), Roserade (Grass), and Machamp (Fighting), all carrying super-effective STAB moves. Ground and Steel-type attackers are also a problem. With 5 weakness types, most competitive teams carry at least one counter. At base 10 Speed, Bonsly won't outrun any of these threats so switching to a resist is usually the safer play.

  • Bonsly evolves into Sudowoodo after learning Mimic. Bonsly is the base form of this evolutionary line.

  • Sturdy is the go-to ability for Bonsly. It prevents being KOed from full HP, leaving 1 HP instead. Its hidden ability Rattled can work in specific setups. Rock Head is the other option — pick based on what your team needs.

  • Bonsly fills the trick room role. It's a physical attacker with base 80 Attack. Base 10 Speed is low. Priority moves or Trick Room are the way to go.

  • Bonsly appears in 13 games, including Platinum, HeartGold & SoulSilver, and Diamond & Pearl.

Bonsly first appeared in Diamond & Pearl and has been available in 13 games across 6 generations. Obtainable through catching or hatching as a base form in most titles where it appears.
