Today San Francisco became Gotham City . Make-a-Wish helped 5-year-old Miles Scott, who has battled leukemia for years, fulfill his dream of becoming Batkid. All over the city, fans came out to cheer him on, and they shared support and snaps on Instagram using the hashtag #sfbatkid.
Batkid was spotted driving around in his Batmobile Lamborghini and rescuing a damsel in distress from the cable car tracks, and another Batman, Val Kilmer himself , even got in on the fun, writing on Facebook: "Just heard the riddler is robbing a bank in the financial district. Hurry #sfbatkid." If you weren't feeling weepy-eyed yet, Batkid's little brother dressed up as Robin. And even President Barack Obama congratulated Batkid on saving Gotham.
We were on the scene at Gotham City Hall, where Mayor Ed Lee gave Miles a key to the city. A US prosecutor and an FBI agent were also on hand to thank Batkid for his service, and he even became a deputized special agent for the Gotham City division of the FBI. San Francisco Police Chief Greg Suhr joked that Batkid would put him out of a job and told the thousands of people gathered that "this is off the hook, San Francisco." Nick Scott, Miles's father, also spoke and said that this big day was closure for the family and Miles, who just went into remission in June after fighting cancer since he was less than 20 months old. See how dreams do come true with a roundup of photos from the day.
