SAN DIEGO – An El Cajon teenager battling cancer, who gained national attention after being surprised by superhero celebrities Robert Downey Jr., Chris Evans and Gwyneth Paltrow in May, was able to experience Comic-Con Thursday.

Ryan Wilcox, 18, has been fighting against a rare blood disorder, but that didn't stop him from making a trip to downtown San Diego for the pop culture convention.

Wilcox, who is one of the biggest fans of Captain America, shared pictures on Facebook of what he experienced at Comic-Con with the caption "Just Awesome!!"

The San Diego Blood Bank also tweeted a picture of him when he stopped by the blood donation area inside the San Diego Convention Center.

In May, Wilcox received the biggest surprise a teenager could imagine.  "Captain America" Evans  flew to El Cajon with his celebrity friends Downey Jr. and Paltrow.  Pictures of Wilcox and the superstars were shared on social media.

Captain America has inspired Wilcox during his long battle with cancer, and Ryan's dream was to meet Evans, the actor who plays his hero.

In early May, Wilcox's classmates at Grossmont High School made a plea to the cast of "Captain America: Civil War" on social media. In the Facebook post, students said meeting the movie cast, especially Evans, would be a dream come true for their classmate.

“He isn’t doing too well and this would be a major way to boost his spirits and, quite frankly, be the best moment of his life, if he literally got to meet his hero,” students said.

On May 6, students decked out in America gear were able to surprise Ryan with a special video message from Captain America.

“I heard you are a big Captain America fan. Good taste!” actor Evans said. “Glad to know you are on team Cap. Just wanted to say stay strong. I know you are fighting the good fight.”

Evans also said he has been inspired by the teenager.

“It’s people like you, with strength like yours, that inspire people like me. So thank you, really, from the bottom of my heart," Evans said.

Evans, like Ryan's classmates, encouraged the teen to stay #RyanStrong.
