Today, Batkid helps save us all from evildoers! And you can watch it happen live.

Batkid, also known as five-year-old Miles, who is battling Leukemia, has inspired 12,000 volunteers to put on superhero capes as the city of San Francisco morphs into Gotham City. It's all a part of the Make-A-Wish foundation.

UPDATE: Photos of Batkid saving Gotham City and winning San Francisco's heart.
