2. The Flash (DC)
Who Is This? Forensic scientist Barry Allen was working in his lab during a storm one night when a bolt of lightning strikes a tray of chemicals soaking him with the electrically charged chemicals, granting him the ability to move at super speed. Berry then adopts the symbol of tha lightning bolt, a red suit and adopts the name "The Flash" to become the protector of Central City.
Why is this person a better choice than WW? Combining elements of the two most famous versions of the flash, Barry Allen and Wally West, The Scarlet Speedster is in many ways DC's version of Iron Man, not going by powers, but by personality - both are witty scientists who begin their journeys as unlikely candidates to be heroes. Sure Barry was police officer, but he was always stuck in a lab somewhere, never a guy to be on the front lines. And similar to Iron Man, the Flash seems to be one of the few superheros who actually enjoys what they do. He gets a kick out of being able to run circles around bigger stronger opponents, much the way that audience would. If DC decides they want to loosen the tone of their movies up a little bit, the one Justice League character who can they can use to soften their super-serious image is the Flash.
Who should be cast? Ryan Reynolds would have been absolutely perfect for the Flash, but thanks to his horrible casting in Green Lantern, thats out the window now - thanks WB! Assuming that he could get a weekend pass off his duties on the Enterprise, Star Trek's Chris Pine would be a great choice for "The Fastest Man Alive."
