In FireRed & LeafGreen, Slowbro looks average on paper at 490 BST. But Regenerator is why it sees play. Build around that and it pulls its weight. C-Tier tank on our tier list. Surf with Leftovers is the standard set.

Does Slowbro mega evolve?

Mega Evolution isn't available in FireRed & LeafGreen, but Slowbro does have a Mega form in Gen 6-7 games (X/Y, ORAS, Sun/Moon). Mega Slowbro hits 590 BST.

What is Slowbro weak to?

In FireRed & LeafGreen, Slowbro's biggest threats include Jolteon (Electric), Exeggutor (Grass), and Scyther (Bug), all carrying super-effective STAB moves. Ghost and Dark-type attackers are also a problem. With 5 weakness types, most competitive teams carry at least one counter. At base 30 Speed, Slowbro won't outrun any of these threats so switching to a resist is usually the safer play.

What is the best ability for Slowbro?

Slowbro gets Regenerator, Oblivious, and Own Tempo. But Regenerator is the one that matters. It's the centerpiece of every viable set. Build around that.

What role does Slowbro play in battle?

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

When a SLOWPOKE went hunting in the sea, its tail was bitten by a SHELLDER. That made it evolve into SLOWBRO.

Slowbro Weakness

Slowbro is weak to Electric, Grass, Bug, Ghost, and Dark. It resists 6 types, so it can switch into a lot of moves safely. Slowbro's physical bulk (base 110 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
