Battle notes

  • Gengar's Ghost / Poison typing is best attacked with Ground (2x), Psychic (2x), Ghost (2x). Start with those attacking types when choosing moves or counter Pokémon.
  • Avoid relying on common Normal, Fighting, Poison, Bug attacks unless they have unusually high power or a secondary purpose, because Gengar resists or ignores those matchups.
  • This guide uses the modern Gen 6+ type chart only. Abilities, held items, Terastallization, weather, fields, and special move rules can still change real battle outcomes.

Gengar's base defensive typing is Ghost / Poison. The weakness chart multiplies both types when a Pokémon has two types, so a matchup can become 4x, 2x, 1x, 0.5x, 0.25x, or 0x.
