Among the many characters Wolfman created or co-created are Cyborg, Raven, Starfire, Deathstroke, Tim Drake, Rose Wilson, Nova, Black Cat, Phobia, Bullseye, Vigilante (Adrian Chase), the Omega Men, and the Nightwing identity of Dick Grayson.

Marv Wolfman was born in Brooklyn, New York City, the son of police officer Abe and housewife Fay.

[3] When Wolfman was 13, his family moved to Flushing, Queens, in New York City, where he attended junior high school.

Neal Adams was called upon to rewrite and redraw a Teen Titans story which had been written by Wein and Wolfman.

When Thomas stepped down, Wolfman eventually took over as editor, initially in charge of the publisher's black-and-white magazines, then finally the color line of comics.

[18][19] During their run on this series, they created Blade,[20] a character who would later be portrayed by actor Wesley Snipes in a film trilogy.

[24] Wolfman and Gil Kane adapted Edgar Rice Burroughs' Barsoom concepts into comics in Marvel's John Carter, Warlord of Mars series.

[29] Wolfman and Keith Pollard introduced the Black Cat (Felicia Hardy) in The Amazing Spider-Man No.

[30] In 1978, Wolfman and artist Alan Kupperberg took over the Howard the Duck syndicated newspaper comic strip.

[38] The New Teen Titans added the Wolfman-Pérez creations Raven, Starfire, and Cyborg to the old team's Robin, Wonder Girl, Kid Flash, and Beast Boy (renamed Changeling).

The first was pencilled by Pérez and sponsored by the Keebler Company,[42] the second was illustrated by Ross Andru and underwritten by the American Soft Drink Industry,[43] and the third was drawn by Adrian Gonzales and financed by IBM.

[46] Other projects by Wolfman for DC during the early 1980s included collaborating with artist Gil Kane on a run on the Superman feature in Action Comics; a revival of Dial H for Hero[10][47] with Carmine Infantino; launching Night Force, a supernatural series drawn by Gene Colan;[48] and a nearly two-year run on Green Lantern with Joe Staton.

[51] After Pérez left The New Teen Titans in 1985, Wolfman continued for many years with other collaborators – including pencillers José Luis García-López,[52] Eduardo Barreto and Tom Grummett.

[53] Claremont immediately declined the offer and told Wolfman that apparently the publisher was looking to replace him on the title.

When Wolfman confronted DC executives about this, he was told it was "just a joke", although Claremont reiterated that he took it to be a credible and official offer.

In 1985, Wolfman and Pérez launched Crisis on Infinite Earths, a 12-issue limited series[54] celebrating DC's 50th anniversary.

[56] Wolfman got into a public dispute with DC over a proposed ratings system,[57] which led to his being relieved of his editorial duties by the company.

[58] DC offered to reinstate Wolfman as an editor provided he apologize for making his criticism of the ratings system public, rather than keeping them internal to the company, but he declined to do so.

[10] Wolfman's writing for comics decreased as he turned to animation and television, though he wrote the mid-1990s DC series The Man Called A-X.

[68] Wolfman's stance was that he had not signed work-for-hire contracts when he created characters including Blade and Nova.

In a nonjury trial, the judge ruled that Marvel's later use of the characters was sufficiently different to protect it from Wolfman's claim of copyright ownership.

[69] In the late 1990s, Wolfman developed the Transformers TV series Beast Machines, which aired on Fox Kids for two seasons from 1999 to 2000.

Beast Machines was met with mixed reviews, as the show was praised for its story, but was criticized for its focus on spirituality.

[70][71] A decade later, Wolfman began writing in comics again, scripting Defex, the flagship title of Devil's Due Productions' Aftermath line.

He worked with Pérez on a direct-to-DVD movie adaptation of the popular "Judas Contract" storyline from their tenure on Teen Titans.

That year also marked Wolfman's first work for Marvel since 1998: a backup story for Bullseye #1, starring the titular character that he had co-created in 1976.

[79][80] On the occasion of the Crisis on Infinite Earths Arrowverse crossover, Marv Wolfman co-wrote an episode of The CW series Arrow with Marc Guggenheim that aired in January 2020.

The Comics Code Authority, which did not permit the mention of werewolves or wolfmen at that time, demanded it be removed.
