Follow This Heartwarming Make-A-Wish Story As It Unfolds

Miles is a 5-year-old boy with leukemia. In their efforts to help make sick kids' dreams come true, the Make-A-Wish Foundation is helping him become a superhero for the day.

Thousands of volunteers in San Francisco came together to help Miles become "Bat Kid" for the day. So far today, he's "saved a damsel in distress", he's helped to "capture the Riddler", and has generally been keeping the citizens of San Fran...erm, I mean "Gotham City" safe.

The San Francisco Make-A-Wish Foundation folks have been posting updates throughout the day, and you can follow the progress of Miles' crimefighting on their Twitter feed and on this Buzzfeed story.
