Marcus Immortus

Marcus Immortus is the son of Immortus, the time-spanning master of Limbo, who was born and raised in that timeless dimension. Stranded in Limbo, he sought a means of escaping into the real world, drawing him into conflict with the Avengers.

Few debut issues carry as much weight — or controversy — as The Avengers #200, the 1980 Bronze Age milestone where Marcus Immortus first stepped onto the Marvel stage, brought to life by the legendary creative team of Jim Shooter and George Pérez. Sharing those iconic pages with Steve Rogers, Tony Stark, Thor, and the assembled might of Marvel's greatest heroes, Marcus made an immediate impression that collectors have never forgotten. Though his appearances across the catalog are select rather than sprawling, they cluster around some notable Avengers collections — The Terminatrix Objective, Avengers Epic Collection, and Avengers Assemble — suggesting a figure whose impact on the team's mythology far outweighs his page count. For any serious Avengers reader, Marcus Immortus is one of those characters whose handful of appearances demand attention, anchored by a key issue debut that remains a talking point across four decades of Marvel history.
