[2] Fall 1941 was a boom period for patriotic superheroes as the country prepared to enter World War II; during this period, comic book publishers also launched Miss Victory, Miss America, U.S. Jones, the Fighting Yank, the Flag, Captain Flag and Yank and Doodle, among others.

[5] Sylvester was a spoiled, pampered rich kid who snuck out of the house to fight crime and evil; his parents never suspected what their son was up to.

According to Jess Nevins' Encyclopedia of Golden Age Superheroes, the Kid's enemies "range from ordinary criminals and Axis agents to the mad scientist Dr. Weerd, False Face, the Black Magician, the moon-mad Moonglow, Presto the criminal magician, and the rope-gimmick using Rope.

Aquaman, Wildcat and the Silver Age Green Lantern rescued the Star-Spangled Kid, who was 50,000 years in the past and hiding in a cave so his flu would not wipe out humanity.

[10] Soon afterward, the Kid refined the technology of the rod, devising a belt with similar powers such as energy projection, flight and matter transmutation.

Sylvester later changes his name to Skyman and becomes the leader of Infinity Inc.[11] During this period, he forms a partnership with Los Angeles to commission the team as for-hire protectors.

Later, he wore a "cosmic converter belt" which enabled him to fly, increased his strength and agility, and gave him the ability to create solid light objects and project energy blasts.
