What Robert Downey Jr. Does For This Boy With One Arm Will Warm Your Heart

Robert Downey Jr. takes his role as Iron Man very seriously, and the actor brought his famous Marvel character to the real world recently when he met with a young boy for a great cause. Robert, who has portrayed Tony Stark in multiple Avengers films, surprised 7-year-old Alex Pring, who was born missing most of his right arm. Alex is in the process of getting a bionic arm made for him by Limbitless Solutions, and the engineering company — along with Microsoft OneNote Collective Project — set out to present Alex with a specially made replica of Iron Man's famous arm, straight from bionics expert Tony Stark himself.
