Una

Una was a Kree woman who first appeared alongside Mar-Vell in Marvel Super-Heroes #12, serving as a fellow Kree soldier stationed on the mission that brought Mar-Vell to Earth and set the stage for his transformation into Captain Marvel.

A child of the Silver Age, Una made her mark when she debuted in the landmark Marvel Super-Heroes #12 in 1967 — a cornerstone issue brought to life by Otto Binder and Don Rico that helped launch one of Marvel's most beloved cosmic corners. Over a span stretching more than five decades, she has kept extraordinary company: sharing pages with Captain Marvel, Carol Danvers, the imperious Ronan the Accuser, and the villainous Colonel Yon-Rogg across the classic Captain Marvel series and its essential collections. With 23 catalog appearances and two recognized key issues to her name, Una is the kind of character that seasoned collectors know to watch for — a genuine piece of Marvel's cosmic foundation whose presence signals you're reading the real thing.
