Terminus

Terminus is a massive, armored alien destroyer who wields an enormous energy lance, dedicated to consuming the resources of entire worlds. He first clashed with Alpha Flight before drawing the attention of the Avengers, establishing himself as a planet-level threat in the Marvel Universe.

Few villains make an entrance quite like Terminus — crashing onto the scene in Alpha Flight Annual #2 in 1987, courtesy of creators Bill Mantlo and June Brigman, this Copper Age Marvel threat has proven surprisingly durable, turning up across nearly four decades of comics. With a catalog presence spanning Avengers titles and that landmark debut annual, Terminus keeps genuinely elite company — sharing pages with Captain America, Iron Man, the Vision, and the Human Torch — which tells you everything about the weight class this character operates in. That one key-issue appearance is a collector's flag worth noting, and any villain who's been menacing Marvel's finest from 1987 all the way to 2025 clearly left a mark worth investigating.
