“Superman -- Weakest Man in the World!”

In "Superman — Weakest Man in the World!", Superman finds himself stranded on a red sun world where every native possesses super-powers—leaving him utterly defenseless. With the fate of Earth hanging in the balance, the Man of Steel must outthink the Thiefmasters' plan despite being the weakest man in a world of giants. Written by Edmond Hamilton and brought to life by Curt Swan’s iconic art and George Klein’s dynamic inks, this 1965 classic features a cover by Swan and Klein that captures the stakes perfectly.
