Sci-fi comics were a groundbreaking genre in the early 20th century. It is taken for granted today, but sci-fi comics were seen as a moral threat to America’s youth back then. EC Comics and other pioneering comic book publishers were forced to stop publishing horror in the mid-1950s.

The sci-fi genre didn’t die out, but there are many early-era sci-fi comics that are historically important today. Censorship authorities tried to wipe out sci-fi and horror comics forever in the 1950s, but did not succeed. 

The sci-fi comics of the 1950s laid the groundwork for the sci-fi we love today. They are also very valuable. 

Here are eight historically important and collectible sci-fi comics you must know about. 

1. Planet Comics #1 (1940) Fiction House

The comic series ran from 1940 to 1974 for over 73 issues. It would feature stories from characters like Mysta of the Moon, Flint Baker, and the Space Rangers. The Red Comet, Reef Ryan, and more. The concept of the space opera would not exist without Planet Comics #1.

EC Comics is infamous for pioneering horror and sci-fi comics in the anthology format during the 1950s.

EC Comics would continue with other comics and began publishing MAD Magazine. 

Weird Fantasy was a notorious anthology comic with confusing numbering. The anthology began as a romance comic, A Moon, A Girl, Romance! but would end at issue #12.
