Nico Castro, a 6-year-old boy with brain cancer, got a break from his chemotherapy that would allow him to trick or treat as Batman on Halloween. Instead, Nico chose to be a superhero to other young patients in the children's ward at Kaiser Permanente Medical Center in Oakland, Calif.
"I was sad they wouldn't have candy," Nico told HuffPost blogger Toan Lam.
With the help of his parents, Nico launched a costume drive and delivered the dress-up donations in time for the big day, NBC News reports.
Nico and his family, who live in San Bruno, Calif., began the drive on Oct. 4, collecting hundreds of costumes, games and even cash, according to People magazine.
"Even though he's going through all these challenges with his medicine and his treatment, for him to be able to think about other kids is such a wonderful attribute," Carla Delemos, a child life specialist at the hospital, told People.
Nico's family recently spoke with HuffPost blogger Toan Lam. Watch the video below and check out photos of Nico's costume drive here.
