Monark Starstalker was, despite a nigh-impossible to say aloud name, a cool Howard Chaykin sci-fi creation for Marvel Comics. The interstellar bounty hunter appeared in Issue #32 of the company's "try-out" title, Marvel Premiere in 1976, but failed to earn his own series. In fact, he wasn't seen again until 2009, guest starring in Nova, and then, a few years later, a Wolverine(!) miniseries.
I have not seen any of those later appearances, but from what I've read online, they really don't sound much like the character Chaykin create in '76.
