MORE: The story behind Mile Scott's wish to become Batkid
Miles has something in common with the caped crusader - bravery. He was diagnosed with leukemia at just 18 months. Fortunately, he's now in remission.
His wish was to become Batman and Make-A-Wish Greater Bay Area made it happen in grand fashion.

Thousands of people helped turn San Francisco into Gotham City to help make his dream come true - he took off in a Batmobile to save a damsel in distress, caught the Riddler red-handed in a bank vault, and chased Penguin through AT*T Park to rescue Giants mascot Lou Seal.
