One of the most prolific and influential writers in modern comics, Marv Wolfman began his career as an artist. Realizing that his talents lay more in writing the stories than in drawing them, Wolfman soon became known for his carefully crafted, character-driven tales.

In a career that has spanned nearly 30 years, Wolfman has helped shape the heroic careers of DC Comics' Green Lantern, Blackhawk and the original Teen Titans, as well as Marvel Comics' Fantastic Four, Spider-Man, and Nova.

In addition to co-creating The New Teen Titans and the universe-shattering Crisis On Infinite Earths with George Purez, Wolfman was instrumental in the revamp of Superman after Crisis, the development of The New Teen Titans spinoff series Vigilante, Deathstroke The Terminator and Team Titans, and created such characters as Blade for Marvel, along with Night Force and the retooled Dial "H" For Hero for DC.

In addition to his numerous comic-book credits, Wolfman has also written several novels and worked in series television and animation, including the Superman cartoon of the late 1980s and currently the hit Teen Titans show on Cartoon Network.
