The man that would eventually be known as Captain Comet made his first appearance at a rally in Washington, D.C. in 1950 where all costumed superheroes were to appear by Presidential decree to show their loyalty, though because he was not yet known at the time as a superhero, he was not allowed to join the other heroes at the rally. When Dynaman was finally exposed as Adolf Hitler's brain being transplanted into Daniel Dunbar's body, most of the known superheroes at the time tried to stop Dynaman's rampage but failed as he was simply too powerful for them to stop. The future Captain Comet decided that he was going to try his hand at taking down Dynaman and flew straight up toward him, but was immediately knocked down to the ground. After Green Lantern arrived and weakened Dynaman with powerful energy ring-enhanced blows before finally being knocked down by a tree, the future Captain Comet again attempted to fell Dynaman, but got a painful groin kick and almost had a school bus crush him to death had not Libby Lawrence (Liberty Belle) jam a broken piece of Ted Knight's (Starman) experimental new cosmic rod through Dynaman's body, electrocuting him to death.
Years later, retired "mystery man" Johnny Chambers (Johnny Quick) noticed that this young hero, whose defiant face graced the cover of a Life magazine issue, not only became Captain Comet, but also was the leader of a new generation of heroes that would usher in the Silver Age.
