The Human Cannonball grew up in a circus, but decided to become a superhero after designing an advanced jet pack which alowed him to crash head first into opponents (wearing a protective helmet, of course). He first appeared when he assisted Lois Lane in battling a super powered Tina Ames. He later competed with Superman for Lois's affections and subsequently helped Lois when she went undercover to expose a baby kidnapping racket. He was also instrumental in helping free Project Cadmus from the evil Adam, but has not been seen since.
Flight pack which can travel short distances.
- This version of Ryan Chase (Earth-One), including all history and corresponding appearances, was initially erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. However the ending of Convergence retroactively prevented that collapse, saving all the alternate realities, though in an "evolved" form. Even though versions of the character may have since appeared, this information does not apply to those versions.
