Tom DeFalco's earliest comic-book scripts were for Archie and DC; he soon moved to Marvel, where he wrote Avengers, Machine Man and other titles, also launching Dazzler, a hit series of the early '80s. In addition to writing long and well-received runs on Amazing Spider-Man and Thor, DeFalco edited many titles, eventually becoming editor in chief. During the 1980s, he headed the creative team that provided fictional biographies for G.I. Joe members, originally included with Hasbro's toys and later used as the basis for multiple storylines on the animated series. Perhaps his best-known work is multi-title character Spider-Girl, whom he introduced in 1998. DeFalco has authored multiple books, including Ultimate Guides for Avengers, Fantastic Four, Hulk and Spider-Man. Ron Wilson began penciling the Thing's Two-in-One adventures in 1975 and remained for most of the title's run.

He subsequently illustrated follow-up series Thing until its end in 1986. Wilson also contributed art for Avengers, Captain Britain, Power Man and other titles, including the entire run of Marvel's licensed Masters of the Universe series. At DC, he provided character designs for the Milestone imprint.
