When there is a Full Moon, this Pokémon likes to scare people by pretending to be their shadow, then laugh at their fear. It is said that if Gengar is hiding, it cools the area by nearly 10 ☏. Levitate makes Gengar immune to Ground-type moves, but this was later removed in Generation VII. In Gigantamax Gengar, it has grown much larger, its red eyes turned yellow with soulless white pupils, the body hasn't changed much, but there is no physical feet visible, its hands are detached and in the ground, its mouth also looks like some sort of room, with a long tounge inside. In Mega Gengar, it has a hot pink smoke around it, and it has a 3rd yellow eye, its hands are buried in the ground, it also got more spikes in its back and tail. Gengar stands on its two short legs, but it can Levitate as well. Gengar has two red eyes and a toothy, sinister smile.
Gengar is a shadow-like, round-bodied Pokémon with two large, pointed ears and short spikes lining its back.
