Like its previous stage, Parasect is an insectoid creature. However, in this stage, the mushroom has completely overtaken the host's body. The insect has been drained of nutrients and is now under the control of the fully-grown tochukaso.
Due to the influence of the tochukaso in its growth, the insect's metamorphosis has been stunted and it instead resembles a grotesque, exaggerated version of its former self. Its pincers and legs have grown much larger and the mushrooms on its back have grown together into one giant mushroom. Its eyes have become pure white resembling those of zombies, likely due to its being possessed by the tochukaso.
The mushrooms that grow on Parasect are often prized by collectors.
The mushroom completely takes over its host's body. Parasect now has more control over it. It still releases irritating spores that can paralyze, poison, or induce sleep in its foes.
Although appearing to be docile, they are actually quite dangerous and will attempt to attack anything that invades their territory. They can use many moves which involve slashing, such as Slash, Cross Poison, and X-Scissor, which makes them quite deadly. Since its evolution, the mushroom is now dictating the actions of the Pokémon in question.
Parasect can often be found in caves, since sunlight and dry air hurt their skin. They can also thrive in dank forests with a suitable amount of humidity, where conditions are ideal for fungi. It is most common in Kanto with a few appearances in Johto, but can be found almost anywhere Paras can be found.
