Last year, the man who plays Tony Stark in the Marvel Cinematic Universe, Robert Downey Jr., delivered a prosthetic 3D-printed Iron Man arm to a boy who was born only with one. This year, he's being a hero once again, fulfilling up a kid's wish.
Dominic, a young boy from Sydney, Australia, struggles daily with cystic fibrosis, but when he teamed up with Make-A-Wish Foundation, hope is restored. A helicopter lifted him up from the playground to a police headquarters where he found his custom, hand-made Iron Boy suit.
Then Dominic went off to save a hostage from some evil minion and eventually went to the Sydney Opera House to fight his powerful nemesis, Ultron.
Robert Downey Jr. sent a video to Dominic, in which he named the kid an honorary Avenger.
