Robert Downey Jr. and Tom Holland have joined their “Avengers” castmates in speaking with 6-year-old Bridger Walker, who saved his younger sister from an attacking dog on July 9.

Bridger’s aunt, Nicole Noel Walker, first caught the attention of Captain America actor Chris Evans with an Instagram post on July 12 in which she tagged several “Avengers” actors. Walker asked them to provide words of encouragement to Bridger, who suffered several bites to his head and required 90 stitches after protecting his younger sister.

Ever since, Walker has documented each conversation between the celebrities and Bridger via social media. On July 16, Walker shared that Evans had sent Bridger a video message in which he promised to give him an authentic Captain America shield, and now Downey Jr. and Holland have followed suit.

In a video message to Bridger, Downey Jr., who plays Iron Man, attempted to one-up Evans’ gift.

“Bridger, you’re a rockstar,” Downey Jr. said. “I hear [Captain America] sent a shield your way. I’m going to do one better, you call me on your next birthday. I’ve got something special for you.”
