Iron Man actor Robert Downey Jr made a disabled boy's day by presenting him with a bionic arm.
Seven-year-old Alex Mead, who was born with a partially developed right arm, received a surprise visit from the actor, who showed up as his Avengers character Tony Stark.
Robert then thrilled Alex even more by presenting him with a very special gift - - a bionic Iron Man arm.
The star then shared a video of the meeting on his Facebook page, and wrote: "Had the absolute privilege of presenting a brand spanking new 3D-printed bionic Iron Man arm to Alex, the most dapper 7-year-old I've ever met."
In the video, Robert compliments the young man's bow tie and inquires about his travels.
He then pulls out two boxes, one with an arm for him and one with an arm for Alex.
The arm was created thanks to Microsoft One Note's Collective Project and Limbitless Solutions, a group that develops affordable 3D-printed limbs.
Robert added: "Special thanks to Albert Manero, OneNote, and #CollectiveProject for their work making artificial limbs like this more affordable for families with kids who want to show the playground how badass they are.

The actor isn't the first member of the Avengers to make a young fan's dream come true: Chris Evans recently visited Seattle Children's Hospital dressed as Captain America.
