Slowbro is technically a pre-evolution of its evolution, but it holds its own in formats where Eviolite is allowed. Ghost moves can't touch it, and only 2 types hit it super-effectively. Flexible enough to run physical or special sets.
The stat bars tell the story: Defense carries everything and Speed's dead weight. But this Hermit Crab Pokemon still yields 2 Defense EVs per fight on a medium-fast 1M XP curve.
Lives lazily by the sea. If the SHELLDER on its tail comes off, it becomes a SLOWPOKE again.
Slowbro Weakness
ExcellentSlowbro is weak to Electric and Grass-type moves. On the flip side, it's immune to Ghost-type moves entirely. The Water/Psychic typing picks up 5 resistances to work with. Slowbro's physical bulk (base 110 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
- 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
Slowbro is the evolved form of Slowpoke, reached at level 37. A Water/Psychic type at 490 stats that still can't breed. Slowbro and Slowking share the same 490 total stats, but they're distributed differently. Check the comparison below to see where each one specializes.
How to Evolve
Slowbro runs a standard attacker set. A nature nature with flexible EVs EVs shapes the build, while an item brings extra utility. An ability supports the kit from the background.

Recommended Teammates
Most of Slowbro's flexibility comes from TMs. Same-type output runs through Psychic and Surf, but Normal and Ice and the rest of the TM pool push it from predictable to genuinely threatening.

Slowbro is a special attacker with base 100 Sp. Atk. Tanky enough to absorb a few hits, too. But the speed tells the real story — base 30 Speed is low. Priority moves or Trick Room are the way to go. Fits the tank role.
