Billy Kidman is the protagonist of the series Template, and the son of the deceased ex-superhero of the same name. His father had intended him to take up his mantle, but Billy doesn't really see the appeal of it: he's an ordinary, bookish sort of chap, who blanches at the barest hint of violence.

Coming home to Rex Falls after his father's death, Billy buys the Myriad Books bookstore from Dorothy Willingham and is determined to live a perfectly ordinary life; however, the vengeful grandson of a supervillain, femme fatales in search of a fictitious book, and a lunatic who might be warning of a threat to reality itself swirl conspire against him.
