Star-Spangled Striplings

After several years as the mascot of the Justice League of America, Lucas "Snapper" Carr attempted to enter adulthood as his own man. Sadly, he was well-known for his honorary status with the League, which caused others in college and the secular arena to view him as still a kid. Bitter from this experience, he was easily manipulated into adopting the alter ego of Star-Tsar, a costumed identity created by the supervillian known as the Key.

Using stellar energized technology, Snapper and the Key each disguised themselves at certain points as Star-Tsar, who had a few confrontations with the criminal Doctor Light and the combined Justice League. However, Snapper eventually realized the folly of turning to crime, and secretly assisted the League in capturing first the Key and then the true mastermind behind Star-Tsar, the hero turned villain known as the Privateer, aka Mark Shaw. From this point, Carr retired from League affairs and became a research scientist at S.T.A.R. Labs in Florida, assisting Supergirl in Florida.

After jumping ahead several decades from his native time due to a cosmic anomaly, the young superhero known as the Star-Spangled Kid attempted to restart his career using the cosmic rod which fellow superhero Starman developed to channel stellar energy through. This led to his joining the Justice Society, at first being a provisional member alongside Power Girl as one of the "Super Squad" which she formed to combat the evil Brain Wave and Per Degaton. Soon thereafter, Kid created a cosmic converter belt based on the cosmic rod which had even greater versatility in its usage, returning the rod to Starman. After several adventures alongside the Society, the Kid retired from superheroics to resume his private life as Sylvester Pemberton, later using his inheritance to purchase Stellar Studios in Los Angeles and fund the new young superhero team known as Infinity, Inc., which his pal Power Girl also joined.

While Star-Spangled Kid and his former sidekick Stripesy had longer costumed careers than had their Earth-One counterparts Star-Tsar and fellow criminal Master Jailer, their adventures during the 1940's mirrored those of the World's Finest Team of Superman and Batman on Earth-One who had more chronicled cases than their Earth-Two counterparts.
