The hero known as Batkid spent Friday restoring peace and order to the people of San Francisco — also known as Gotham City for the day— and smiles to people all across the Internet.
If you're just getting up to speed, "Batkid" is a five-year-old boy named Miles who's currently battling leukemia. His biggest wish? To be Batman for a day. So the San Francisco Make-a-Wish Foundation set about making that happen. But they got more than they bargained for when more than 10,000 strangers volunteered to help bring Miles one magical day.

Thousands of cheering fans lined the streets of San Francisco as Batkid saved a damsel in distress after the Riddler tied her to train tracks, stopped a bank robbery, rescued San Francisco Giants mascot Lou Seal from the vile Penguin and attended a press conference in which Mayor Ed Lee presented him with a key to the city.
Batkid's appreciative fans flocked to social media to record the spectacle. By 4 p.m. San Francisco time, more than 10,000 Instagram photos had been posted with the hashtag #SFBatKid. We've rounded up 25 of our favorites in the gallery above. And as an added bonus, you can check out footage of Batkid rescuing his damsel in distress right here:
