SAN FRANCISCO (CBS SF) — A young leukemia patient realized his dream to become Batman for a day as an army of volunteers transformed part of San Francisco into ‘Gotham City’ Friday.

5-year-old Miles Scott from Siskiyou County traversed the city Friday, maneuvering through huge throngs of admirers as a superhero named “Batkid,” fighting crime with the help of the Make-A-Wish Foundation.

Volunteers, businesses, the San Francisco Giants and even the city’s mayor and police department all pitched in to make the adventure as realistic as possible.

Miles has become an internet sensation as the project which has taken on a life of its own through social media. The 5-year-old was diagnosed with leukemia when he was 20 months old and ended chemotherapy treatment in June, with the cancer now in remission, Make-A-Wish Greater Bay Area executive director Patricia Wilson said.

“He already battled a villain in real life. He fought cancer and won,” Wilson said.
