Batkid, also known as Miles Scott, battled leukemia and is now in remission. The Make-A-Wish Foundation and the city of San Francisco made his dream come true a week ago by organizing a day of heroism for him.
Now, the family has started the Batkid Fund.
"We are eternally grateful and humbled by the outpouring of love and compassion we've received since Miles had his wish to be Batkid," his parents, Nick and Natalie Scott said, in a statement.
"We were honored to receive many offers of gifts or assistance, but now that Miles' leukemia is in remission, we want to use this moment to draw attention to other parents who are coping with serious illness," they said.
The family partnered with the San Francisco Forty Niners' Foundation to create the Batkid Fund. All the proceeds from the fund will be split evenly between the three organizations that helped the family cope during Miles' three-year battle: Make-A-Wish, the Ronald McDonald House and the Asante Rogue Regional Medical Center in Oregon.
"I hope you will join us in supporting and helping others," the parents said. "It seems only fitting that following a day when the world demonstrated caring and compassion for Batkid ... Batkid can now help others."
The world watched last Friday at Miles' wish to be Batman came true.
Batkid's day began with the San Francisco Chronicle's entire front page dedicated to him, his own Batmobile and a city-wide adventure that included rescuing a damsel in distress, foiling the Riddler's bank robbery and saving San Francisco Giants mascot Lou Seal from the Penguin.
The Internet was overtaken with Batkid fever throughout the day. The hashtag #SFBatkid was quickly trending on Twitter and everyone from politicians to actors to athletes were tweeting about Batkid.
From Friday to Sunday, there were more than 600,000 tweets with the #SFBatkid or #Batkid hashtags, according to Make-A-Wish. More than 16,000 Instagram photos with the hashtag were shared. The foundation said that the total reach of all social media users who used the hashtags was 1.7 billion people.
The wish also spiked donations for Make-A-Wish and interest in volunteering.
