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.

Slowbro Weakness

Excellent

Slowbro 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.

Gen I Type Chart
  • 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

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.

    or evolve from Slowpoke (Step 1)
  • At 490 BST, Slowbro is firmly in pre-evolution territory. Evolve it into Slowking before bringing it to any serious fight.

  • Slowbro's biggest threats include Jolteon (Electric) and Exeggutor (Grass), all carrying super-effective STAB moves. Only 2 weaknesses means fewer dedicated counters to worry about. At base 30 Speed, Slowbro won't outrun any of these threats so switching to a resist is usually the safer play.

  • Slowpoke evolves into Slowbro at level 37. Slowbro is the final evolution in a 5-stage line starting from Slowpoke. At 490 BST, it's got solid stats to work with.

  • 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.

  • Slowbro appears in 21 games, including Yellow, Red & Blue, and Gold & Silver.

Available since Red & Blue, Slowbro appears in 21 games spanning 9 generations. Beyond its original form, it gained a Mega form in Generation 7 and a Galarian form in Generation 8.
