Lifeforce

Lifeforce made their Marvel debut in 1995's X-Men '95 #1, brought into the Copper/Modern Age by a creative team that included J. M. DeMatteis, Ralph Macchio, Terry Dodson, and John Paul Leon — a genuinely impressive roster of talent for a first appearance. Though their catalog footprint is compact, Lifeforce's presence across titles like Wolverine and Wolverine: Origins puts them squarely in the orbit of one of Marvel's most beloved and ferocious characters, sharing pages with the likes of Logan himself alongside figures such as Hurricane, Spyne, and Gauntlet. The fact that Lifeforce earned a place in the All-New Official Handbook of the Marvel Universe A to Z speaks to a character with enough staying power and intrigue to merit the completist treatment — a quiet badge of legitimacy in the Marvel universe that any deep-cut enthusiast will appreciate.
