Opul Lun Sat-Yr-Nin

Few Marvel villains carry an air of aristocratic menace quite like Opul Lun Sat-Yr-Nin, who slithered onto the scene in Captain Britain #6 in 1985 — a Bronze Age creation from the wickedly talented team of Jamie Delano and Alan Davis. Over a publishing span stretching all the way to 2021, this enigmatic figure has haunted the pages of Excalibur and Captain Britain alongside some of Marvel's most beloved characters, including Captain Britain himself, Meggan, and Kurt Wagner. With only a handful of catalog appearances, Sat-Yr-Nin is a rare, choice discovery for collectors who love the layered, Britain-rooted corner of the Marvel universe — the kind of deep-cut character whose every appearance feels like a find worth celebrating.
