Tony Stark Delivers 3D-printed Bionic Iron Man Arm To Deserving Seven Year Old

Oh sure, humor wise, he's dryer than a desert river bed. Beneath his overly wry exterior, beats the deeply scared, golden heart of one who's been through the depths of hell and has come back better for it. This is Tony Stark, doing good.

Meet Alex. He was born with a partially developed right arm. he is seven. He LOVES superheros. He rocks a red bow tie.

Meet Tony Stark, zillionaire playboy, mad industrialist and yes, full time Iron Man. He deeply appreciates a well rocked red bow tie.

Enter one Albert Manero, partnered with Stark, a #CollectiveProject student who founded Limbitless, a collective making artificial limbs like this more affordable for families with kids who want to show the playground how badass they are.

All three make this video pretty great.
