Five year-old Miles has been battling acute lymphoblastic leukemia since he was 20 months old. He wanted to be Batman for a day, and the Make-A-Wish Foundation made it happen. Today San Francisco transformed in to the dark and gritty Gotham City with the help of 11,000 volunteers. Miles saved a damsel in distress, drove around in the Batmobile and served some good old fashion justice to the Riddler and Penguin.

The #SFBatKid went viral with touching photos of BatKid saving the day:
