J. T. Slade

Debuting in the pages of The Mighty Avengers #18 in 2008, J. T. Slade is a Modern Age Marvel creation from the acclaimed team of Brian Michael Bendis and Stefano Caselli, stepping onto the scene during one of comics' most politically charged, espionage-driven eras. With appearances spread across Secret Warriors, Siege, and Mighty Avengers, Slade moves in serious company — sharing pages with the likes of Nick Fury and Daisy Johnson — placing them squarely in the shadowy, high-stakes corners of the Marvel Universe. A collector-recognized key issue among their 23 appearances signals that this character's entry into comics was no throwaway moment. Compact in catalog footprint but connected to some of Marvel's most compelling storytelling of the late 2000s and early 2010s, J. T. Slade is exactly the kind of figure that rewards the deep-diving fan.
