Like its pre-evolution, Gloom has a blue-colored body. However, it now has a reddish-brown, white-spotted "flower" atop its head. The "flower" resembles a rainforest flower, the rafflesia, which is said to smell like rotten meat. The leaves it had as an Oddish seems to be withering underneath the flower. Gloom's eyes seem perpetually closed in appearance, and their purple lips seem to drip drool constantly, however, the 'drool' is actually nectar. Gloom has gained a pair of arms, and its legs seem more developed in form.
