Mercury (Lev Gleason)

Golden Age Origin
Mickey O'Toole is in need of a blood transfusion and is given blood by the Silver Streak. Because of the "secret fluid" in the Streak's blood, Mickey gains the Streak's powers, and becomes first Mercury and then the Meteor, the Streak's sidekick. The Meteor has super-speed and can fly.
