Arthur Slater was taken from his parents at a young age and barely remembers them. He passed through a series of county homes and foster homes, and eventually wound up with the Folsoms -- a couple in their thirties who had very strict ideas about discipline and training. His powers first manifested themselves when his foster mother was spraying him in the eyes with a water pistol as punishment for not listening when she spoke (he'd been reading). He dissolved her arm, and then -- in horror -- sealed over the stump. He then fled the house, and wound up in the local nature preserve. 

Arthur is an extremely powerful psychic, but his power is limited to range of thirty two feet and four inches. Within that sphere, he can do virtually anything -- including teleport. He closed most of his power off after injuring his foster mother, then began exploring it more carefully so that he wouldn't starve in the woods. 

He was found in the Preserve by the Alpha Hound Lynx, and her acting hunter, Hunter Dee -- Harbinger, from Saint Vincent's School for Exceptional Youth. They managed to convince the boy to return to the police with them and testify against his foster parents. Given a choice between remaining in the foster system, coming to Saint Vincent's, or joining the Hounds, Arthur chose to come to Saint Vincent's.
