Guardians of the Galaxy #55

The 31st-century Guardians of the Galaxy face a serious threat in issue #55, as the cover — penciled by Kevin West and inked by Steve Montano — puts a massive, horned armored figure center stage, crackling with energy while a blue-skinned Guardian and a red-and-yellow female teammate scramble to confront him, and a large bestial creature looms from the lower right. The cover boldly promises readers they'll "Meet Ripjak — The Interplanetary Serial Killer," and that tagline alone makes this December 1994 entry in Marvel's far-future series one to seek out. If you've been following the Guardians through the Marvel 3000 era, this looks like exactly the kind of cosmic confrontation that makes the title so much fun.
