Gloom Yellow Guide
At 405 BST, Gloom is firmly in pre-evolution territory. Evolve it into Vileplume before bringing it to any serious fight.
In Yellow, Gloom's biggest threats include Scyther (Bug), Charizard (Fire), and Cloyster (Ice), all carrying super-effective STAB moves. Scyther is the most dangerous since Bug moves deal 4x damage. Flying and Psychic-type attackers are also a problem. With 5 weakness types, most competitive teams carry at least one counter. At base 40 Speed, Gloom won't outrun any of these threats so switching to a resist is usually the safer play.
Gloom is a mixed attacker with base 65 Attack and 85 Special. 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.
In Yellow, 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.
For Yellow, the core moveset is Sleep Powder, Stun Spore, Solarbeam, and Megadrain. Sleep Powder leads at 0% usage. This set covers the trick room role with a mix of damage and utility.
