Manga Hulk by “Lone Wolf and Cub” Creators
Ever heard of Manga Hulk? Long before they got around to manga-fying the X-Men, Marvel decided to give Japanese creators a chance to reinvent popular superhero characters, including Manga Hulk ("Haruku"), back in 1970. They chose Kazuo Koike -- the legendary creator of "Lone Wolf and Cub" -- as the writer, with Yoshihiro Morifuji on art. Although the Hulk in this version is still a scientist, he's named Dr. Araki instead of Dr. Banner, and in a poignant addition to his backstory, he's also a Hiroshima survivor.
