Fresh off their "civil war," the actors who portray Iron Man, Captain America and Pepper Potts put aside their differences to become real-life superheroes and visit a fan afflicted with cancer.

Avengers stars Robert Downey Jr. , Chris Evans and Gwyneth Paltrow assembled to make a devoted fan's wish come true.

On Monday, the stars of the blockbuster films flew to San Diego to meet 18-year-old Ryan Wilcox, who has been diagnosed with leukemia for the second time.

Ryan, a massive fan of the films and comic books, started an online campaign "#RyanStrong" to try and meet the stars.

Paltrow was the first to notice and recruited her co-stars to spend a day with the teen.

Ryan's mom, Amy, told the Associated Press: "She told me this is a gift from one mom to another mom. She knew how happy it would be for me to see Ryan so happy."

Taking to Instagram, the Oscar-winner said: "Today @ryanwilcox0303 got a little surprise. Thank you to the incredible #chrisevans and my better work half @robertdowneyjr for being the men you both are. And thank you to the Wilcox family for your hospitality!"

When they arrived at his home, Ryan was wearing a Captain America shirt and smiled from ear to ear. Ryan says the films keep him distracted when he is going through chemotherapy treatments.

The trio helped Ryan find the courage he needs to beat his condition.

"I am going to get through this," he told The AP.

Earlier this month, Evans showed his support to Ryan in a YouTube message filmed prior to their time together.

Ryan was diagnosed with the rare blood cancer when he was 16. When he was three, he underwent treatments for a brain tumor.
