Clothed in a Batman costume, with fists clenched tight, a 5-year-old boy took the city of San Francisco as his favorite superhero.

Suffering from leukemia, the 5-year-old Miles Scott wooed the social media and thousands of fans including the White House, as he lived his dream of being a "Batkid".

"When you have an illness, it's very important to know you have a support system," said Gina Futrell, a 51-year-old with multiple sclerosis, who was among a large crowd gathered at Union Square for a chance to so see the "Batkid" in action. "I have an extremely strong support system, and I hope he does too. He's such a little hero."

"Batkid was called into service by Police Chief Greg Suhr and spent the day zooming from one "crime scene" to the next. Accompanied by an adult Batman impersonator, Batkid rescued a damsel in distress from cable car tracks, captured the Riddler as he robbed a bank, and saved the San Francisco Giants mascot - Lou Seal - from the Penguin's clutches," wrote a local news website.

Miles was able to live his wish through the Make-A-Wish Foundation. He was diagnosed three years ago, underwent chemotherapy treatment and is now in abeyance.
