After co-creating DC's Swamp Thing in 1972, Len Wein moved to Marvel for lengthy runs on some of the company's biggest titles - Amazing Spider-Man, Fantastic Four, Incredible Hulk and Thor - and helped bring the landmark Giant-Size X-Men #1 into the world, changing Marvel forever. Returning to DC as an editor, Wein oversaw an influx of British writing talent, highlighted by Alan Moore's historic Watchmen miniseries. Wein also has worked in television and animation, returning to his roots to develop a Swamp Thing screenplay. He has written comic-book adaptations of The Simpsons and Futurama. An award-winning writer since 1973, Marv Wolfman succeeded mentor Roy Thomas as Marvel's editor in chief. Well-remembered for his Tomb of Dracula scripts, he also enjoyed runs on Dr. Strange, Fantastic Four and Nova, among other titles. New Teen Titans, his 1980s collaboration with George Perez, became DC Comics' biggest hit in years. Wolfman and Perez literally rewrote DC history with Crisis on Infinite Earths. He subsequently penned episodes for such animated TV series as G.I. Joe, Transformers and others. Bill Mantlo began his Marvel career on Deadly Hands of Kung Fu, in which he introduced White Tiger, one of the industry's earliest Hispanic super heroes. Eventually writing stories for almost every Marvel title, he did some of his most fondly remembered work on Incredible Hulk and Spectacular Spider-Man. He also launched Cloak and Dagger in a pair of miniseries and guided Alpha Flight through some of its most harrowing ordeals. Mantlo excelled at integrating licensed properties into the Marvel Universe, as demonstrated by Micronauts and Rom- Spaceknight, both of which he wrote from start to finish. At DC, he wrote the Invasion miniseries for one of the company's biggest crossover events. In 1976, Ross Andru (1927-1993) made comic-book history by penciling the first large-scale intercompany crossover, Superman vs. the Amazing Spider-Man, having spent years illustrating both characters in various titles. He also made Marvel history in Marvel Feature, drawing the Defenders' first appearance. At DC, he spent nine years collaborating with Bob Kanigher on Wonder Woman. With Marv Wolfman and Mike Esposito, he co-created Vigilante (Adrian Chase). After a start as inker to his older brother John, Sal Buscema penciled Captain America, Defenders, Incredible Hulk and more. Famed for his ability to meet tight deadlines, he spread his talents across multiple genres. His 1970s work ranged from Ms. Marvel and Nova to Sub-Mariner and Spider-Woman's first appearance in Marvel Spotlight. He was the uninterrupted artist on Spectacular Spider-Man for more than one hundred issues and penciled the web-slinger's adventures in Marvel Team-Up, in which he and writer Bill Mantlo introduced Captain Jean DeWolff. After handling more team-ups in the Thing's Marvel Two-in-One, he reunited with brother John on Steve Englehart's Fantastic Four. He later provided inks for Tom DeFalco's Spider-Girl titles and Thunderstrike miniseries. A creative stalwart that put his all into his work on long-running series like Ghost Rider and Defenders, Don Perlin plied his talents in virtually every discipline in the comic-book field - penciling, inking, creating new characters and sometimes editing and writing. A student of Burne Hogarth's, Perlin launched his career in 1951, drawing horror comics for various publishers and also penciling Will Eisner's The Spirit. After serving in the Army, Perlin returned to comics with Harvey in the late '50s as well as Charlton in the '60s. In 1973, he began his long association with Marvel, finishing John Buscema's art on Thor and inking several titles. He took over Werewolf by Night from Mike Ploog, penciling and inking the book for much of the next two years. He also penciled and inked the supernatural adventures of Johnny Blaze in Ghost Rider, his name becoming very closely identified with Marvel's monster biker. In the '80s, he drew Defenders for a long run before turning his attention to Marvel's adaptation of Hasbro's Transformers. His early '90s work on Valiant's Solar, Man of the Atom and Bloodshot was extremely popular, after which Perlin went into semiretirement.
