Robert Downey Jr. plays a superhero in movies, but the guy is also something of a hero in real life.
Case in point: A 7-year-old boy named Alex was born with a partially developed right arm.
So, Tony Stark himself decided to deliver Alex a new bionic arm that looks just like Iron Man's.
A college student and bionics whiz named Albert Manero heard about Alex's story and built the little guy a low-cost bionic limb.
Both Downey Jr. and Alex tried on their robot arms when they met due to the efforts of The Collective Project and Albert.
Basically, this is a feel-good story in which a little kid gets to be a real-life Iron Man with the help of Iron Man.
