Gloom sits in the middle of its evolution line — stronger than Oddish but not yet at full power. Most trainers push through to Vileplume as fast as possible. Known as the Weed Pokemon. Flexible enough to run physical or special sets.
Nothing fancy in Gloom's spread. It leans mixed with Sp. Atk out front. And you'll get 2 Sp. Atk EVs per KO for it. Follows a 1.06M XP medium-slow curve.
The nectar it drools from its mouth smells so atrocious that it can make noses curl from more than a mile away.
Gloom Weakness
VulnerableGloom is weak to Fire, Ice, Flying, and Psychic-type moves. The Grass/Poison typing picks up 5 resistances to work with.
Gloom can evolve into Vileplume and Bellossom. Gloom sits before the split, so check the evolution methods below to pick your path. HP has grown the most so far (+15), but there's still another 95 stats to gain in the final evolution.
How to Evolve
Don't let the NFE status fool you. Gloom with Eviolite hits bulk numbers that compete with final forms. Max HP and Sp. Def EVs and Calm nature maximize that, and Stench handles the rest.

Recommended Teammates
The level-up pool tells the story here. Gloom learns Moonblast and Petal Dance naturally, plus enough variety that TMs feel like bonuses. Fairy and Normal coverage extends the reach beyond that.

At 395 BST, Gloom is firmly in pre-evolution territory. Evolve it into Vileplume before bringing it to any serious fight.
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 special attacker with base 85 Sp. Atk. Enough bulk to take a hit or two, too. But the 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.
