Hudnall's parents divorced when he was two and his mother remarried to a man in the US Navy. The family settled in San Diego, California in the 1970s, and after graduating from Point Loma High School, Hudnall joined the U.S. Air Force in 1976. He was stationed in England.

After his discharge from the Air Force, Hudnall went to Coleman College in San Diego where he majored in computer science. He worked as a computer software consultant in Orange County, California, Sonoma County, and briefly in England.

In 1985 he started working with Eclipse Comics as a marketing director in order to learn the comics business. In 1986 his first comic, Espers, got him enough acclaim to get a job at Marvel and DC. From there he went on to work for almost all the major publishers in American Comics, including Image, Dark Horse and Malibu.

Hudnall switched from writing comics to internet development in the late 1990s, while producing more limited work over the years, such as Trigs for Humanoids and 2 To the Chest from his own company Dark Planet Productions.

In 2009 he began writing for the conservative media criticism blog Big Hollywood which was founded by Andrew Breitbart.
