The Avengers' Robert Downey Jr. is as much a real-life hero as he is on screen.
Last year, Downey delivered a prosthetic Iron Man-style arm to a young boy who was born with a partially formed right arm.
Dominic from Sydney, Australia suffers with the life-threatening genetic disorder cystic fibrosis. Make-A-Wish Foundation made it possible for him to save the day by being lifted by helicopter to police headquarters, where he proudly donned his Iron Boy getup.
When RDJ learned about Dominic, he sent him this video proclaiming him an honorary Avenger.
You go, Dominic! What a brave young hero.
Be sure to catch Robert Downey Jr. as Iron Man in Captain America: Civil War on May 6.
