This new Hulk feature was initially scripted by Lee, with pencils by Steve Ditko and inks by George Roussos. Other artists later in this run included Jack Kirby (#68–87, June 1965 – Oct. 1966); Gil Kane (credited as "Scott Edwards", #76, (Feb. 1966)); Bill Everett (#78–84, April–Oct. 1966); John Buscema (#85–87); and Marie Severin. The "Tales to Astonish" run introduced the super-villains the Leader, who would become the Hulk's nemesis, and the Abomination, another gamma-irradiated being. Marie Severin finished out the Hulk's run in "Tales to Astonish". Beginning with issue #102 (April 1968) the book was retitled "The Incredible Hulk" vol. 2, and ran until 1999, when Marvel canceled the series and launched "Hulk" #1. Marvel filed for a trademark for "The Incredible Hulk" in 1967, and the United States Patent and Trademark Office issued the registration in 1970.
