Carlton Velcro

Carlton Velcro made his entrance in 1986 through Editora Abril's Superaventuras Marvel, a Brazilian publication that brought Marvel's martial-arts world to a whole new readership — and this Copper Age villain has lingered in the catalog across a remarkable stretch of nearly four decades. With only four catalogued appearances, Velcro is a rare and elusive figure, the kind of deep-cut antagonist that serious collectors love to hunt down. He shares his pages with a stellar cast — Shang-Chi, Leiko Wu, Black Jack Tarr, and Denis Nayland Smith among them — placing him squarely within the hard-hitting, globe-trotting world of Marvel's kung fu comics. If you're piecing together the full picture of that era's Brazilian releases, Carlton Velcro is exactly the obscure gem worth knowing.
