Powell has written and provided artwork for franchises of Dark Horse , DC Comics and Marvel , but is most regarded for his original series The Goon, which debuted from the small publisher Avatar Press. Powell quickly switched to self-publishing under the moniker Albatross Exploding Funny Books, before being picked up by Dark Horse after only a handful of issues. The Goon's quality was recognized with an Eisner Award in 2004 for Best Single Issue (Dark Horse The Goon #1) as well as an International Horror Guild award. The following year Powell won Eisner's Best Humor Publication and Best Continuing Series awards.
He is a featured interviewee in the movie Independents.
