[2] The character was popular enough to get a brief solo series, published in Summer and Fall 1941.

[4] Jonathan Battle was the youngest combatant in World War I, and lost his eye.

[5] Since then, Jonathan Battle uses his jetpack, called a luceflyer, and a series of fantastic inventions to prevent World War II from taking place, including a Curvoscope, which allows him to see anywhere on the Earth by following the curvature of the Earth, and Dissolvo, which breaks down nerve and bone tissue into gelatin.

[1] In his first three-part story, Captain Battle fought an Asian wizard known as the Black Dragon, and his army of Deaglos, humans that the Dragon had transformed into angry bird-men.

At the end of the story, the surviving Deaglos were changed back to human — including an orphan, Hale, who became Battle's ward and teenage sidekick.
