Character: green day (jjba)
Green Day is the stand of Dr. Cioccolata, a tertiary villain from JoJo's Bizarre Adventure Part 5: Vento Aureo.
Green Day is an artificial humanoid stand with red eyes, green skin, no nose, and 3 fingers. The tubes on its head, shoulders, and fingers are used to disperse spores.
Green Day is a close range/power type stand with an area of effect. Its ability: "Mold Infestation" allows it to release fungal spores from the mushroom like tubes on its body. Any one at a lower altitude to Green Day who moves to a lower altitude will suddenly become infested by the spores which causes the flesh to rapidly rot away and disintegrate. The effect is described as being very similar to that of cordyceps and other species of parasitic fungus. Because the spores are release rapidly and airborne, if Cioccolata can get to a very high altitude, he is capable of effectively gassing entire cities worth of people. When a person is killed by the stand, their corpse will also release mold, effictively giving the stand an infinite area of effect. The stand is also incapable of distinguishing targets, meaning that in situations where Cioccolata is deployed he will more or less nuke/carpet bomb the entire area. The only people who are immune to the stands effects are Cioccolata himself and his pet gimp Secco, who's stand Oasis protects him with an airtight suit of body armor.
