The real-life Avenger didn't let this young fan down.
Back in January 2017, Aaron Hunter sent a message out into the world, calling on social media to help him reach Iron Man himself, Robert Downey Jr.
"My name is Aaron Hunter, and I need to speak to Iron Man," he says in the video, surrounded by Avengers memorabilia. "Iron Man, if you see this, I really, really need your help."

Aaron goes on to explain that he has a rare disease called rapid-onset obesity with hypothalamic dysregulation, hypoventilation, and autonomic dysregulation (ROHHAD). "Some of my friends with ROHHAD have died. I don't want any more of my friends to die," he says, calling on Iron Man to help him raise money and awareness for ROHHAD.
