Theresa Cassidy

Theresa Cassidy arrived in the Bronze Age pages of Spider-Woman #37 in 1981, the creation of the legendary Chris Claremont alongside Steve Leialoha and Terry Austin, and she's been a fixture of Marvel's mutant landscape ever since. With over four decades of continuous publication and 204 catalog appearances — six of them collector-recognized key issues — she's proven herself one of the more enduring figures to emerge from that fertile early-'80s era of Marvel storytelling. Her deepest roots run through X-Force, X-Factor, and Deadpool, where she's kept company with a vivid ensemble including Rictor, Tabitha Smith, Roberto Da Costa, and James Proudstar, and her X-Men affiliation places her squarely at the heart of Marvel's mutant mythology. If you're tracing the long, rich thread of the X-corner of the Marvel Universe from the Bronze Age right into the present, Theresa Cassidy is a name you'll want to know well.
