Gastly Best Moveset
Ghost/Poison at 100 Sp. Atk and 80 Speed with AbilityLevitate granting Ground immunity. The Sp. Atk is impressive for a pre-evolution but 30 HP and 30/35 defenses mean any hit connects for a KO. The moveset needs evolution. Gengar at 130 Sp. Atk and 110 Speed is the goal.
100 Sp. Atk on a first-stage Pokemon in Gen I (Red & Blue). Ghost/Poison with Levitate later. 30 HP and 35 defenses fainted to any breeze.

Gastly Weakness
Gastly is weak to Ground, Psychic, Ghost, and Dark. On the flip side, it's immune to Normal and Fighting-type moves entirely. The Ghost/Poison typing picks up 4 resistances to work with. Levitate grants an additional Ground immunity, reshaping the matchup chart. Gastly leans toward special offense (base 100 Sp.Atk) instead of trying to wall anything.
| Damage | Types |
|---|---|
| 2x (Weak) | Ground, Psychic, Ghost, Dark |
| 0.5x (Resist) | Grass, Fairy |
| 0.25x (Resist) | Poison, Bug |
| 0x (Immune) | Normal, Fighting |

Base Stats
Nothing fancy in Gastly's spread. It leans special with Sp. Atk out front. And you'll get 1 Sp. Atk EV per KO for it. Follows a 1.06M XP medium-slow curve.
It wraps its opponent in its gas-like body, slowly weakening its prey by poisoning it through the skin.
Gastly Guide
For a casual playthrough, Gastly works as a placeholder. Ghost/Poison coverage is useful early. The real payoff is Haunter. That's where the stats start mattering.
Game Availability
Present since Red & Blue, Gastly appears in 22 games spanning 10 generations. Gen 1 originals like Gastly have the longest track record of availability in the series.
