Metal Men #5

DC's quirky robot team faces their most outsized threat yet in Metal Men #5 (1963), subtitled "Menace of the Mammoth Robots!" The cover by Ross Andru and Mike Esposito throws the team into glorious chaos — a towering green Robot Queen looms menacingly while the Metal Men scramble below, one slender member swinging a chain lasso in a desperate bid to bring the giant down, as teammates in various metallic forms brace and stumble against the creature's crushing advance. It's the kind of imaginative, high-stakes cover that captures exactly what made this series such a distinctive corner of DC's early 1960s lineup.
