DC superheroes are nothing if not troubled, and while Wally West may be most familiar to fans thanks to WB's animated Justice League, his mentor Barry Allen had his life was shattered before Wally was ever born - at least, it was in Geoff Johns' Flash: Rebirth reboot (2009).
When his mother was found murdered in his childhood home, Barry's father was wrongfully convicted of the act and imprisoned. In an effort to save his father, Barry dedicated his life to criminal forensics; determined to advance the science of catching killers, and the integrity of police work.
Allen's life changed forever when bathed in chemicals and struck by lightning, granting him super-speed. The cause of his powers may need to be updated, but a hero fast enough to save any life from ruin - except his own - would be right at home in WB's budding universe.
