About this Issue

ThunderCats #1 marks the debut of the entire ThunderCats cast in comic book form — the first time Lion-O, Cheetara, Panthro, Tygra, WilyKit, WilyKat, Snarf, Jaga, Mumm-Ra, and the Mutants (S-S-Slithe, Jackalman, Monkian) ever appeared on a printed comics page. As one of Marvel's Star Comics imprint's inaugural titles, it arrived simultaneously with the animated series' first season, making it a vivid snapshot of mid-1980s franchise publishing at the height of the licensed-property comics boom. The issue's close fidelity to the pilot episode also cemented a storytelling model — TV-episode adaptation blended with original comics content — that the series would sustain for all 24 issues and that Marvel UK would later replicate across 129 weekly issues. Its demand was strong enough to warrant multiple printings within the same cover-dated month, an early sign of the franchise's cultural grip on young readers.

History

ThunderCats was conceived by writer Tobin 'Ted' Wolf, who pitched his humanoid-cat-people concept in early 1984 to Stan Weston of Leisure Concepts Inc., which in turn brought it to Rankin/Bass Productions; Leonard Starr was then hired as head writer to develop the series bible, create the characters, and script the pilot episode 'Exodus.' Marvel's Star Comics imprint — launched in December 1985 specifically to serve younger readers with licensed-property comics — selected ThunderCats as one of its debut titles, assigning scripter David Micheline to adapt Starr's 'Exodus' teleplay under editor Mike Carlin (with Tom DeFalco as executive editor and Jim Shooter as editor-in-chief). Penciler Jim Mooney and inker Brett Breeding produced both the interior art and the cover, with Petra Scotese handling colors; Breeding would later go on from this early career work to co-create Doomsday at DC in the 1990s. The copyright notice in the issue credits Leisure Concepts, Inc., Telepictures Corporation, and Ted Wolf — reflecting the complex multi-party licensing arrangement that governed the franchise from its inception.
