Earlier this week we learned about 6 year old Bridger Walker saving his 4 year old sister from a dog attack.
Bridger required a two hour surgery and 90 stitches to his face.
Chris Evans, aka Capt America, sent the 6 year old a video message.
He commended the boy for his bravery and said, I'm going to track down your address and I'm going to send you an authentic Capt America shield because pal, you deserve it.
Mark Ruffalo, Tom Holland, Hugh Jackman, Zachary Levi are all among those who have reached out to Bridger.
What is the bravest thing your sibling ever did for you?
