Revy was entirely immoral, thinking very little of murder, arson, wanton destruction, and other acts of violence. His sole interests were in money, a hedonistic lifestyle, and his many Dunsparce.
Revy's past is largely unknown, but at some point he discovered a large number of Dunsparce, and abandoned the Lapras he had been using as transport at the time, along with its egg, to train the Land Snake Pokemon.
An unknown period of time after this, in the interim of which Revy terrorized large portions of the world, he sailed to Ransei, where he pledged in service to the Ghost Lord. He became, for a time, the Ghost Lord's attack dog, aiding in the suppression of a local rebellion.
His last assignment was when he was sent to Yaksha to bring it to heel. Though he entered the city with little difficulty, when he reached the home of Fukurou, he was killed by him and Andante working in concert.
After his death, his body was taken to Kin Island by the Dunsparce Legion, and used as fertilizer for lichen and other plants. To this day, the descendants of the Legion still inhabit the island, though some have been taken by PEFE!Every for study.
Revy's primary ability was his affinity with Dunsparce. He trained several hundred of them as his personal army, using a handful as direct aides, while a far greater number of them composed an amorphous swarm he referred to as the Dunsparce Legion.
He fought with a pair of Dunsparce (named Guinevere and Giuseppe) clinging to his wrists, using their drills as flails, stabbing weapons, and Thunder Wave generators. Meanwhile, a third Dunsparce (named Harrison) fought next to him using standard attacks, often Rock Slide.
In addition to this, he used the Dunsparce Legion, often in the form of a gigantic serpent, to run interference and deliver incredibly powerful attacks based off the strength of the Legion as a whole, particularly Rages, Headbutts, Body Slams, and Ancient Powers.
Revy's control over his Dunsparce was absolute. With a series of subtle hand signals and spoken orders, he could cause them to form a variety of different shapes depending on necessity.
- Was enemies with Fukurou and Andante, and was killed by the latter. He swore a blood oath that his descendants would kill those of Andante, but so far it hasn't worked out in his favor.
- Due to having a woman in every port, Ever, Brie, Lepiota, PEFE!Every, Amanita, and All are all descended from him, Amanita in particular from a random Spectran servant.
