Patrick Kelly was originally an ace fighter pilot in World War II who fought in the Pacific Theater under General Stilwell, as a member of the Avenger Corp. He was from Brooklyn. He was later transported to the future, where he explored the galaxy and continued to defend freedom as a rocket pilot. He was called to another planet where he became the Keeper of the Flame of Democracy, the flame being a mystic energy felt by the free people of the universe. Kelly was accompanied on his adventures by his World War II gunner Punchy (originally called Whacky) who was a former Brooklyn cab driver, and a beautiful nurse named Sue Andrews (she was later replaced by a girl named Diana). Kelly's enemies included Indus, Vengo and Diablo, who was determined to extinguish the Flame of Democracy.
