Back in 2013, the Make-A-Wish Foundation in San Francisco helped five-year-old Leukemia patient Miles Scott realize his dream of becoming a superhero by putting together an entire day full of activities where this young "Batkid" helped save the city. This remarkable story was captured in last year's documentary Batkid Begins, which was beloved by fans and critics alike. Today we have yet another heartwarming story about another elaborate Make-A-Wish event in Australia for nine-year-old Domenic Pace, which ended with Robert Downey Jr. himself making this brave young boy an honorary Avenger.

Domenic Pace, who suffers from Cystic Fibrosis, has always been a lifelong /captain-america-civil-war-photos-winter-soldier-iron-man/Iron Man fan, at times even referring to himself as "Tony," and at one point he proclaimed himself "Iron Boy" at the dinner table. Make-A-Wish Australia helped make young Domenic's dream of becoming a superhero come true, by organizing an elaborate event that turned this heroic youngster into Iron Boy for the day. Domenic was taken by helicopter to New South Wales police headquarters, where he was shown a video from New South Wales Police Commissioner Andrew Scipione. Domenic was given the mission of saving reporter Hope Joy, who had been kidnapped by Ultron.

Domenic was given a custom Iron Boy costume and he was taken to Clark Island to save Hope, along with older brother Joseph, who participated in the event as "Colonel Rhodes." The youngster was then taken to the iconic Sydney Opera House where he took on Ultron himself, in front of a massive crowd of fans, before being given the Medal of Valour by Scipione. At the end of the day, Robert Downey Jr. even sent his own message to Domenic, congratulating him on saving the day, and making him an honorary Avenger, something he doesn't do every day.

Of course, this isn't the first time that Robert Downey Jr. stepped up to brighten the day of a youngster in need. Back in March, the actor teamed up with The Collective Project to present a custom 3D-printed Iron Man prosthetic arm to a 7-year-old fan with an underdeveloped limb. Then in October, the actor sent out a special video to another 7-year-old fan with Cystic Fibrosis, inviting him to the premiere of Captain America: Civil War.

We also have Robert Downey Jr.'s video message below, plus a tweet that the actor sent out in support of Domenic Pace. What do you think about Robert Downey Jr. reaching out to a young fan? It's certainly possible that, with Captain America: Civil War arriving in theaters this May, the actor will embark on even more charitable endeavors, so be sure to stay tuned.
