The Bandit Robots of Metropolis
Superman Sunday Newspaper Strip - October 27, 1940 to December 15, 1940
As far as “Iconic Superman Stories” go, you can’t get much better than “The first time Superman fought an army of robots”.
Titanic mechanical men perform destructive raids upon Metropolis and only Superman stands in their way. When Lois is inevitably abducted by the masterless robot menaces, the Man of Steel follows them to their lair to destroy them once and for all.
It’s worth mentioning that the inspiration for this story is usually credited to Norvell W.Page, the author of the lion’s share of pulp hero The Spider’s adventures. In this case, the shadowy hero met robotic giants in a tale with the typically understated title of “Satan’s Murder Machines” (Reprinted in more mellow times as as “Robot Titans of Gotham” and “The Iron Man War”).
