Jealousy (The Amazing World of Gumball)

Jealousy is a single-appearance character in The Amazing World of Gumball. So far, it only appears in the episode "The Flower." Jealousy is apparently a pure manifestation of jealousy that can possess anyone or anything, causing the victim to turn a shade of green, and gain its face as well as its voice. It also causes its victim to reveal something they always wanted, except for those who are happy with their life as it is like Darwin. He also plays a main role in the online game Class Spirits, a minor role in Fellowship of the Things as one of Gumball's abilities, and an appearance in the mobile game Rainbow Ruckus.
