Carlos

A Silver Age original, Carlos made their Marvel debut in the very first issue of Amazing Adventures in 1970 — a Jack Kirby-crafted launch that immediately signals this character's pedigree. That premiere issue carries collector-recognized key status, and it's easy to see why: sharing those early pages with Black Widow and the royal Inhumans — Medusalith, Gorgon, Triton, and Karnak — puts Carlos right at the heart of one of Marvel's most ambitious anthology launches. Though their catalog footprint is a modest five appearances spread across nearly five decades, Carlos remains a genuine piece of Silver Age history, the kind of supporting player that devoted readers of Amazing Adventures and the Black Widow Epic Collection will recognize as part of the texture that made Marvel's early 1970s universe feel so richly populated.
