Captain America is giving a special gift to one brave little boy.

In a video message to Bridger Walker, 6, who saved his four-year-old sister from a dog attack, Chris Evans, well known for his role as Captain America in the Marvel Cinematic Universe, called the young boy a “hero” and said that what he did was “so brave” and “so selfless.”

Evans went on to say that he would track down Walker’s address in order to send him an “authentic Captain America shield.”

As the story goes, Walker jumped in between his sister and the attacking 1-year-old old German shepherd mix. While protecting his sister, Walker was brutally injured and subsequently underwent a two-hour surgery that required more than 90 stitches, according to his family.

When Walker’s father asked him why he jumped in between his sister and the dog, Walker said, “if someone had to die, I thought it should be me,” according to the statement from the family.

Anne Hathaway also praised Walker for his bravery and love for his little sister, saying that she knows “a superhero” when she sees one.

Walker’s family revealed that Mark Ruffalo, Tom Holland, Hugh Jackman, Zachary Levi, the Russo brothers and Robbie Amell also reached out to Walker after hearing his story.
