Batkid, aka Miles Scott, remains cancer-free five years after battling both leukemia and the villains of Gotham City.

As reported by the San Francisco Chronicle, Miles was granted a wish by the Make-a-Wish Foundation in 2013 to become Batman, effectively turning San Francisco into Gotham City for a day with the help of 12,000 volunteers.

Miles cruised around the city in a Lamborghini that was made to look like the Batmobile, answered a call from the police commissioner, and faced down the Riddler and Penguin, ultimately being awarded the key to the city. According to the foundation, Miles received his last treatment just before becoming Batkid.

Miles was diagnosed with acute lymphoblastic leukemia when he was 20 months old, but he beat it and the villains of Gotham in one fell swoop. Now, Miles is 10 and his cancer is in remission. Reports say his once daily doctor visits are down to only once a year. A fifth-grader, Miles enjoys science, robotics, and playing little league baseball.

“This wish meant closure for our family and an end to over three years of putting toxic drugs in our son’s body,” said Miles’ mother Natalie Scott at the time. The experience ultimately served a great purpose: following Miles’ larger-than-life story, donations to the Make-a-Wish Foundation shot up drastically.

A year following the event, Miles was supposed to make a surprise return as Batkid at the Oscars alongside Andrew Garfield, though the appearance was suddenly canceled the day of the event. In 2015, a documentary about Miles’ heroics called Batkid Begins: The Wish Heard Around the World was released to positive reviews.
