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. Few can match Ron Frenz 's record of substantial stints on two of comicdom's most influential and revered characters, Spider-Man and Superman, both of whom he provided with controversial new looks.

Frenz succeeded John Romita Jr. on Amazing Spider-Man, and his artwork was favorably compared to Steve Ditko's original web-slinger. With Roger Stern, he introduced the Hobgoblin, covering the mysterious villain's debut and revealing his identity more than a decade later in Hobgoblin Lives. With writer Tom DeFalco on Thor, Frenz debuted a new look and identity for Marvel's Thunder God, eventually branching into Thunderstrike. Later, Frenz and DeFalco launched the MC2 Universe, home of Spider-Girl, the only Marvel heroine to reach one hundred consecutive issues.
