Adaga de Prata

Stepping out of the vibrant Brazilian comics scene of the early 1980s, Adaga de Prata made their debut in Superaventuras Marvel #13 (1983), brought to life by the creative team of Jotapê Martins alongside the legendary Frank Miller and Klaus Janson — a Bronze Age pedigree that's hard to top. Published by Editora Abril, this character emerged from one of Brazil's most beloved Marvel imprints, sharing pages with a remarkable roster that includes Matt Murdock, Homem-Aranha, Capitão América, and Homem de Ferro. With only four catalogued appearances, Adaga de Prata is a rare gem for collectors with a taste for the distinctive intersection of Brazilian publishing history and Marvel's Bronze Age storytelling — exactly the kind of discovery that makes digging through back issues so rewarding.
