Fortress Maximus

Few Transformers carry the sheer presence of Fortress Maximus, who thundered onto the scene in Marvel's The Transformers #39 in 1988, courtesy of writer Bob Budiansky and artist José Delbo. Emerging at the tail end of the Copper Age, this towering figure made an immediate impression, sharing the pages with the likes of Spike Witwicky, Cerebros, and Brainstorm in a run that crackled with the epic scale the series was known for. With only a handful of catalog appearances, Fortress Maximus is a rare find — the kind of character whose limited footprint only deepens the mystique for dedicated collectors hunting down every corner of Marvel's beloved Transformers universe.
