The Death-Ray by Daniel Clowes

Teen outcast Andy is an orphaned nobody with only one friend, the obnoxious – but loyal – Louie. They roam school halls and city streets, invisible to everyone but bullies and tormentors, until the glorious day when Andy takes his first puff on a cigarette. That night he wakes, heart pounding, soaked in sweat, and finds himself suddenly overcome with the peculiar notion that he can do anything. Indeed, he can, and as he learns the extent of his new powers, he discovers a terrible and seductive gadget – a hideous compliment to his seething rage – that forever changes everything.
