Gengar is the mischievous shadow, a grinning prankster with a penchant for chilling maneuvers. It thrives in victory through sneak attacks, with a sly grin that embodies the thrill of the ghostly unknown.
Gengar is said to be the shadow of Clefable, suggesting they share a special connection in the Pokémon world.
Gengar's Japanese name, Gangar, is possibly a play on the word doppelgänger, a spirit double or evil twin, reflecting its ghostly nature and tendency to mimic the shadows of other creatures.
