Batkid returned to Gotham City on Saturday, but this time, he took off his black mask and let the crowds meet the real kid underneath the costume.
Five-year-old Miles Scott of Tulelake, Siskyou County, arrived in San Francisco to cheer folks on at "Brave the Bay," formerly known as the SFPD Challenge.
The pint-sized Dark Knight kicked off the 5K Run at Aquatic Park in San Francisco to benefit the Make-A-Wish Foundation- and raise money for other sick children - while leading a Santa Walk along the chilly bay with his parents, Nick and Natalie Scott, and his younger brother. Of course, he was wearing his sneakers with orange Velcro straps.
When he wasn't suited up in costume, he was wearing a San Francisco 49ers sweatshirt and shook hands with happy passersby - and even got to sign autographs at the 49ers vs. Seattle Seahawks game on Sunday.
He took his fame with stride. When asked what he wanted to tell all his admirers, Miles answered: "I don't know."
His dad, Nick Scott, stepped in to save him: "Oh, it's a happy day," he said. "I'm glad everybody could come out. We love all this attention. We didn't expect him to be a celebrity. But if he can help anybody by dressing up and being Batkid, that's what we want."
Matt Suhr, the son of San Francisco Police Chief Greg Suhr, raised $30,000 in "Batkid" T-shirt sales, all of which are being donated to Make-A-Wish.
The shy kindergartener with bright blue eyes was last in town on Nov. 15 when he was the recipient of an internationally inspiring volunteer effort, noted by everyone from the Harlem Globetrotters to President Obama.
While sick with leukemia - from which he is now in remission - Miles told the Make-A-Wish people that he wanted to be "Batman for a day." He was able to realize his dreams and beyond when 12,000 volunteers got wind of his request, and the city of San Francisco morphed into Gotham City for a day.
Now, Miles is helping the police officers realize their goal to raise $75,000 to help grant wishes for 357 children with life-threatening medical conditions. Organizers are hoping to help 10 children on Saturday alone.
