The Martian Manhunter (J'onn J'onzz) is a fictional character that appears in publication published by DC Comics. Created by writer Joseph Samachson and artist Joe Certa, the character first appeared in Detective Comics #225 (Nov. 1955).
The character of J'onn J'onzz has featured in other DC Comics-endorsed products such as video game, television series, animated film, and merchandise such as action figure and trading card.
The Martian Manhunter debuted in the back-up story "The Strange Experiment of Dr. Erdel" in Detective Comics #225 (Nov. 1955), written by Joseph Samachson and illustrated by Joe Certa; the character is a green-skinned extraterrestrial humanoid from the planet Mars, who is pulled to earth by an experimental teleportation beam (originally presented as an attempted communication device) constructed by Dr. Erdel. The shock of the encounter kills Dr. Erdel and leaves J'onn with no method of returning home. The character decides to fight crime while waiting for Martian technology to advance to a stage that will enable his rescue. To that end, he adopts the identity of John Jones, a detective in the fictional Apex City (later retcon as Chicago).
During this period, the character and his back story differ in some minor and some significant ways from modern treatments. Firstly, as with his counterpart, the Silver Age Superman, his power range is poorly defined, and his powers expand over time as the plot demands. The addition of precognitive abilities (Detective Comics #226) are quickly followed by telepathy and flight, "Atomic vision", super-hearing, and many other powers. In addition, his customary weakness to fire is only manifested when he is in his native Martian form.
