Cloud

Cloud is a mysterious being of uncertain identity who joined the Defenders, a non-team of Marvel heroes including Beast, Iceman, and Valkyrie. Possessing the ability to transform into an actual cloud, they later revealed a startling dual nature — existing as both male and female.

Drifting into Marvel continuity in the pages of The Defenders #136 in 1984, Cloud is one of the Bronze Age's more intriguing enigmas — a character whose very presence alongside luminaries like Hank McCoy, Iceman, Valkyrie, and Warren Worthington III signals that they ran in genuinely remarkable company. Though their catalog footprint is selective, Cloud's story stretches across an impressive arc from that Bronze Age debut all the way through the recent Defenders: Beyond, proving that some characters leave a lasting impression that outlasts their page count. For collectors with an eye for the unusual and underappreciated corners of Marvel history, Cloud is exactly the kind of discovery worth chasing down.
