Blok

A mysterious presence lurking in the pages of Marvel's Wolverine, Blok surfaced in 2001 courtesy of creators Frank Tieri and Sean Chen — right in the thick of the Modern Age when Logan's solo title was firing on all cylinders. With only a handful of catalog appearances, this is a rare, blink-and-you'll-miss-it figure who shares the page with Wolverine himself, making every issue count for the dedicated completionist hunting down every corner of the X-Men universe's rougher edges.
