Caduceus

Debuting in the pages of The Spectacular Spider-Man Annual #8 in 1988, Caduceus is a Marvel creation from the Copper Age, brought to life by the celebrated team of Gerry Conway and Mark Bagley. This intriguing figure has turned up across a surprisingly eclectic range of Marvel real estate — from Marvel Comics Presents to the cosmic sweep of Eternals Annual and the collected grandeur of the Evolutionary War Omnibus — suggesting a character whose story touches some of the publisher's more ambitious, large-canvas storytelling. Along the way, Caduceus shares adventures with an unusual cast including Highnote, Sea Witch, and Raoul Hernandez, hinting at a corner of the Marvel Universe that rewards the curious digger. With a publishing footprint stretching across 23 years, this is exactly the kind of quietly persistent character that devoted collectors love to track down.
