An estimated 13,000 people turned out to support Batkid in San Francisco. Many volunteered time as actors, videographers and in other roles. One person donated a Lamborghini for the day to be the Batmobile.

Foiling the Riddler's Bank Robbery

With the help of the San Francisco Police Department, Batkid foiled the Riddler's bank robbery and took him into custody. The U.S. Attorney's office issued a news release thanking Batkid.

Superhero Lunch

After two heroic acts, it was time for Batkid to take a break and have a burger near Union Square. Even superheroes need to eat, after all.
