Johnny Wulgaru aka Dread is the arch villain of the epic and sweeping Otherland series authored by Tad Williams. He is a character of consummate evil. A serial rapist and murderer. He was born with an ability to modify electronic devices through mental powers. It was an ability he nurtured and trained. He became an extremely well paid assassin, using his innate ability, his ingrained sadism, and his developed skills. In an extraordinarily pathetic climactic sequence, he becomes trapped in a gigantic computer network, living out his worst nightmares til the end of time (or until the indefinite future when someone would pull the plug on the whole deal).

All in all, not overly approachable individual.
