Sometimes superheroes are real.

Chris Evans, Ryan Reynolds and Paul Bettany joined forces after a reporter relayed the wishes of a dying boy.

He probably has just days and all he wants is a greeting from one of the Avengers, Fox News Channels Shannon Bream tweeted.

The superheroes jumped to the rescue.

Happy to! Evans, who plays Captain America, responded.

Bettany, who voiced J.A.R.V.I.S. in the Iron Man films and plays Vision in The Avengers also reached out, while Ryan Reynolds joked that hes more of a Reserve Avenger.

His Deadpool will debut in Avengers: Infinity War next month.

Elizabeth Olsen, who plays the Scarlet Witch, sent along a video message, Fox told the Daily News.

The details about the young boy, Emilio, are unclear.

At the Critics Choice Awards in 2016, Reynolds dedicated his entertainer of the year award to the young fans with cancer.

Deadpool was an 11-year odyssey for me to get up here, and it resonated with a lot of people, he said.

The character had cancer and some of the people that this character resonated with were sick kids. I would like to dedicate this honor to the Make-A-Wish Foundation and the SickKids Foundation of Toronto, two incredible organizations that do so much for so many kids in need.
