Cosmic Boy:Matt Dallas
founding member of the Legion of Super-Heroes, and was the original leader in all incarnations of the Legion.His character has been fairly consistent in past versions, with a serious attitude and a strong sense of duty, while the "Threeboot" version leans on the manipulative side.
