Earlier this month, the Make-A-Wish foundation transformed San Francisco into Gotham City. Miles Scott, a five year old leukemia patient, had his dream come true and was Batman for the day. This morning, he got to put on the cape and cowl again, and appeared on Good Morning America with his family.

At the end of the interview, Batkid was informed that the Joker had locked music superstar Pitbull in his dressing room. While most would have let the Joker have his way with Pitbull, Batkid proved that he was a true hero and actually went to save him! Check out the video above to hear more about Miles Scott's incredible battle with cancer and watch him save the day one more time.
