Silver Streak is a fictional superhero character created by Joe Simon that first appeared in Silver Streak Comics #3 (cover-dated March 1940), from Lev Gleason Publications. He is believed to be the second-ever comic book superhero whose primary power is speed; All-American Publications' The Flash preceded him by two months. However, Silver Streak beat out National Allied Publications' Johnny Quick (who debuted in 1941) as the first superhero whose two powers were speed and flight. Silver Streak has a kid sidekick called "Mercury" (soon changed to "Meteor"); he is also assisted by a falcon named "Whiz".
