Gloom Guide

  • At 395 BST, Gloom is firmly in pre-evolution territory. Evolve it into Vileplume before bringing it to any serious fight.

  • In FireRed & LeafGreen, Gloom's biggest threats include Charizard (Fire), Cloyster (Ice), and Dodrio (Flying), all carrying super-effective STAB moves. Psychic-type attackers are also a problem. At base 40 Speed, Gloom won't outrun any of these threats so switching to a resist is usually the safer play.

  • In FireRed & LeafGreen, Oddish evolves into Gloom at level 21. Gloom can evolve into Vileplume and Bellossom depending on the method. Gloom is a middle-stage evolution in the Oddish line.

  • Gloom gets Chlorophyll and Stench. But Chlorophyll is the one that matters. It's the centerpiece of every viable set. Build around that.

  • Gloom is a mixed attacker with base 65 Attack and 85 Sp. Atk. Enough bulk to take a hit or two, too. Speed tells the real story. Base 40 Speed is low. Priority moves or Trick Room are the way to go. Fits the trick room role.

Game Availability

Present since Red & Blue, Gloom appears in 21 games spanning 10 generations. Gen 1 originals like Gloom have the longest track record of availability in the series.
