Gengar
- Hypnosis
- Thunderbolt
- Night Shade
- Explosion
Gengar is the only viable Ghost-type in RBY OU and therefore has the unique defensive niche of being immune to Normal-type attacks, which means it can come in on Body Slam or Hyper Beam from Snorlax, absorb any Explosion, and block Wrap. Gengar is also the fastest sleep-inducing lead in the game, which lets it beat other sleep leads such as Jynx. Thunderbolt is its best attack, hitting most Pokemon for neutral damage and giving it a fighting chance against Starmie despite its weakness to Psychic. Explosion lets Gengar heavily dent special walls it lures in such as Alakazam and Chansey, and OHKO them if they are chipped. Since Gengar is weak to any potential Psychic or Earthquake from Pokemon such as Jynx, Exeggutor, Starmie, Rhydon, Tauros, and Alakazam, it must take care to avoid both attacks.
