Marvel Comics Characters By Andy Jones

Creatively and commercially, the '90s were dominated by the use of gimmickry to boost sales, such as variant covers, cover enhancements, swimsuit issues. In 1991 Marvel began selling Marvel Universe Cards with trading card maker SkyBox International. These were collectible trading cards that featured the characters and events of the Marvel Universe. The following year, Marvel acquired the Fleer Corporation, also known primarily for its trading cards.
Another common Marvel practice of this period was regular company-wide crossovers that threw the universe's continuity into disarray. In 1996, Marvel had almost all its titles participate in the "Onslaught Saga", a crossover that allowed Marvel to relaunch some of its flagship characters, such as the Avengers and the Fantastic Four, in the Heroes Reborn universe, in which Marvel defectors (and now Image Comics stars) Jim Lee and Rob Liefeld were given permission to revamp the properties from scratch. After an initial sales bump, sales quickly declined below expected levels, and Marvel discontinued the experiment after a one-year run; the characters soon returned to the Marvel Universe proper. In 1998, the company launched the imprint Marvel Knights, taking place within Marvel continuity; helmed by soon-to-become editor-in-chief Joe Quesada, it featured tough, gritty stories showcasing such characters as the Inhumans, Black Panther and Daredevil.
