Gloom Guide

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

  • 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.

  • 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 leaning toward the special side (base 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.

  • For a casual playthrough, Gloom works as a placeholder. Grass/Poison coverage is useful early. The real payoff is Vileplume. That's where the stats start mattering.

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.
