The U.S. has Batkid, and now Australia has Iron Boy!
The Make-A-Wish Foundation granted nine-year-old Domenic's wish to become Iron Man and battle Ultron.
Domenic, a Sydney native living with cystic fibrosis, suited up as Iron Boy and took on the bad guys.
Iron Man himself, Robert Downey Jr., who is in disguise because of Captain America: Civil War, even cheered young Domenic on and made him an honorary Avenger.
Brother to Thor and Australian native Liam Hemsworth cheered Domenic on as well.
