San Francisco has transformed into Gotham City today to help make a little boy's Make-A-Wish dream come true.

Miles Scott loves superheroes, especially Batman. And like Batman battles villains, Miles has been fighting his own battle with leukemia since he was just a year old. Miles is now in remission and he is getting his chance to be Batkid for a day with the help of Make-A-Wish of the Greater Bay Area, city of San Francisco and hundreds of folks who are willing to play along.

"This wish has meant closure for our family and hopefully an end to his fight against this illness", Miles' mom Natalie said.

The day started with Miles, aka "BatKid", being alerted to trouble in Gotham City. Miles then spent the day battling some of the comic hero's most notorious criminals and will receive a special thank you from Mayor Ed Lee.

No doubt a great day for a brave little boy...as brave as any superhero!
