Hasbro and Marvel teamed up in 1985 to produce three mini-comics for G.I.Joe Action Stars Cereal. These comics introduced Starduster, the Joes new Jet Pack Trooper. Hasbro and Marvel teamed up again in 1993 to produce four mini-comics that were included in some 1993 figure packages (ex. seen here).
Series: G.I.Joe Action Stars cereal mini-comics (1985)
Hasbro and Marvel teamed up to make three mini-comics featuring Starduster. These were inserted in select wave two boxes of G.I.Joe Action Stars cereal. These comic books are dated 1985, and the G.I.Joe Mobile Strike Force offer on the back of each issue expired 1/31/87. So, we can assume that these offers were available at least as early as 1985 and as late as early 1987.
1993 mini-comics (figure inserts)
These mini-comics were included with some 1993 figures (ex. seen here).
