Leader

Samuel Sterns was a laborer exposed to gamma radiation who developed an enormous, green-domed head and superhuman intellect, becoming the Leader — a megalomaniacal genius and one of the Hulk's most persistent foes, using his vast mental powers to pursue world domination.

Emerging from the Bronze Age pages of Etranges Aventures in 1972, Leader is a figure whose catalog presence spans an impressive 34 years — a quiet testament to lasting appeal. Brought to life by the creative pairing of Arnold Drake and Bob Brown, this character keeps genuinely distinguished company, sharing adventures with the likes of Hulk, Bruce Banner, Captain America, and Steve Rogers across a run that includes two collector-recognized key issues. Published under the Panini France banner with Hulk serving as their most frequent stomping ground, Leader may not boast the widest catalog footprint, but for fans of Bronze Age comics with a European flavor, those 15 appearances are well worth hunting down.
