Portabello

Portabello are Bug / Poison-type monsters.

Physiology
Contrary to popular belief, the monster is really the mushroom cap which has connected itself to the insectoid of its choice. Portabellos were originally created by scientists as a way of controlling disease-spreading insects. These insects are really more like zombies that Portabellos have full control over.

Special Abilities
Portabellos have been genetically modified so that they can attach themselves to an insect host and shoot spores into their bodies, which gradually takes over the brain. The fungus then kills the host, and fruiting bodies erupt from the ant's head and spread more spores. The host's body is cold and dead, but the Portabellos can control the bodies with its spores.

Behavior
Portabellos are plants with one thought pattern: take control over the nearest living organism. The genetic modification only allowed for them to take over certain insects, but their spores can still cause headaches.

Habitat
Portabellos mainly appear in moist, cold, and dark places, like near water or in a cave, but are common in forests as well, as a singular, grounded entity. However, Portabellos are able to use their host to scavenge their needs, like taking cold water from their bodies, allowing for more roam.

Origin
Portabellos are based on a real life parasitic relation between the Ophiocordyceps fungus and ants.

Name Orign
Portabello is a common type of mushroom, used mostly in cooking.
