Impidimp

Impidimp is a small fuchsia Pokémon with a large head, small body, and wiry limbs. Its hands have three fingers each while its feet don't have digits. Its face has a purple "mask", prominent pointed ears, large eyes with small pupils, a long nose with a single nostril, and a fanged mouth. It usually has its purple tongue sticking out. The back of its head sports a tuft of hair that resembles a bat wing. It and its evolved forms are a male-only species.

Impidimp is a mischievous Pokémon that loves to sneak into people's houses to steal things and generally be a nuisance to their occupants. This allows them to feed on negative emotions that Impidimp causes and they siphon the negative energy of their annoyed targets by sucking through their noses.
