Brothers Chuck and Hal Chandler were born in Los Angeles, California. As a test pilot for NASA in 1958, Chuck was piloting the experimental XF-13 rocket plane when he was captured by Skrull invaders. They attempted to interrogate him, but Chuck escaped, damaging the Skrulls' warp drive in the process. The Skrull saucer exploded as Chuck flew away, exposing him to strange radiation. He crashed the XF-13 in the Mojave Desert, and when his younger, crippled brother Hal attempted to rescue him, Chuck disappeared, believed to have been killed. Hal, a research scientist, discovered that Chuck's image had been imprinted on the lenses of his glasses, and that Chuck had been transformed into a two-dimensional being. When Hal wore the glasses and concentrated, he triggered a dimensional shift that caused Chuck to materialize into a three-dimensional existence. In his new form Chuck wore a green and red bodysuit, and his normal strength, speed, and durability had been tripled.
