Gloom is a blue, bipedal Pokémon with rudimentary hands and feet. It has orange leaves and a reddish-brown flower growing from its head. The flower has large, rounded petals and white spots. The female displays only a single large spot on each petal, while the male will have more, smaller spots. Its eyes are wide and often appear closed and its lips are thin and purple. Gloom trickles sticky nectar from its mouth with the appearance and consistency of drool. Gloom lives in grassy plains.
