Wonder Man is a fictional superhero created by American cartoonist Will Eisner, whose only appearance was in the comic book Wonder Comics #1 (May 1939). The character is of some historical significance due to a lawsuit that resulted from his only appearance.

Wonder Man's secret identity is Fred Carson, radio engineer for the International Broadcasting Corporation. During an excursion to Tibet, an old monk bestows Carson with a ring that gave him the power to fight evil when the need arose.^[1] His powers are almost exactly like those of Superman.^[2] He travels to war-torn Tatonia, beats up the invading dictator General Attila, and stops the war. Then he rescues his boss's daughter, Red Cross nurse Brenda, and kisses her.^[3]

Wonder Man was created by Will Eisner in the Eisner & Iger Shop for Victor Fox, who was publishing astrology magazines when he ran across his distributor's reports on the incredible sales for National Periodicals' Action Comics in February 1939. He immediately decided to get into the comic book business, setting up offices in the same building DC had theirs, then contacted Eisner. Using the pen name Willis, Eisner wrote and drew the first issue of Wonder Comics, which appeared on the newsstands less than six weeks later.
