Kooba Kid

Origin
In 1940, Victor Fox, publisher of Fox Syndicate comics, decided that he would cash in on the soda pop craze (Coke and Pepsi both being extremely popular at this time) by publishing ads for "Kooba Cola" in his comics. There was no such cola but, Fox thought he could drum up interest, then sell the license for Kooba Cola to one of the major soft drink companies. The Kooba Kid would drink Kooba Cola and then gain super strength to battle schoolyard bullies. Either there were multiple young boys who would gain super strength when drinking the soda or one character whose hair would switch from blond to red and back again depending on the appearance.
