Skyman

Sylvester Pemberton

DC Comics' Skyman was the original Star-Spangled Kid, Sylvester Pemberton, a Golden Age character. He became the Star-Spangled Kid in order to battle Nazism during World War II. He was unique in that he was a kid superhero who had an adult sidekick, Stripesy a.k.a. Pat Dugan. Both he and Dugan were superb acrobats along with having sufficient training in hand-to-hand combat.

Pemberton then changed his name to Skyman and founded Infinity Inc. Skyman led the team until his accidental death at the hands of Mister Bones.

Jacob Colby

52 presents Jacob Colby as one of the first official subjects for Lex Luthor's "Everyman Project". Luthor's project grants super-powers to Colby, who is given the codename Skyman after Luthor buys the rights to Infinity Inc. from the Pemberton Estate. This Skyman had the power to control the air, and the power of flight. Colby later becomes romantically involved with his teammate Starlight.

It is later revealed that Colby had been killed by his teammate, Everyman, who consumed Colby's body and gained the ability to assume his form, posing as Colby since his murder (fooling even Starlight with his deception).
