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.
It looks as if it is always crying. It is actually adjusting its body’s fluid levels by eliminating excess.
It prefers arid environments. It leaks water from its eyes to adjust its body’s fluid levels.
Bonsly Weakness
FragileType-wise, Bonsly takes extra damage from Water, Grass, Fighting, Ground, and Steel. It resists 4 types, giving it decent defensive coverage. Bonsly's physical bulk (base 95 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
- Fairy type does not exist — Dragon has fewer checks
- Physical / Special split now per-move (introduced Gen IV)

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.
