Sina

Sina made their debut in the pages of Superaventuras Marvel #45 in 1986, brought to life by the legendary creative pairing of Chris Claremont and John Byrne during the rich Copper Age of comics. Published by Editora Abril, Sina's appearances span a remarkable 26 years across Superaventuras Marvel and Marvel Série I, sharing those pages with compelling figures like Raven Darkhölme, Irene Adler, and Dominikos Petrakis — Avalanche himself. A character with a modest but intriguing catalog footprint, Sina is one of those quietly fascinating discoveries that reminds collectors just how wide and wonderfully varied the Marvel universe truly is.
