A six year old boy is getting a lot of praise for an act of bravery.
Bridger Walker from Wyoming received 90 facial stitches after he intervened when a dog approached his sister.
After the boy deliberately stepped in front of his sister, the dog attacked him, biting his face and head.
Despite his injuries, the boy grabbed his sister's hand and the pair ran.
An Instagram post from his aunt has gone viral with the hopes of attracting some attention from a Marvel superhero.
So far Hulk actor Mark Ruffalo has responded, as has Captain America himself, Chris Evans.
Evans sent the boy a video, promising to send him one of Cap's shields, saying 'Pal, you deserve it...We need people like you."
