SAN DIEGO (CBS 8) - Ryan Wilcox, 18, who is fighting against a rare blood disorder called secondary Myelodysplastic Syndrome or MDS, received a superheroes visit on Monday.
When he was three-years-old, Ryan battled a brain tumor and received a bone marrow transplant in April of 2015.
Being a huge fan of Captain America and the Avengers, friends and family set out to make Ryan's dream come true of meeting his favorite superheroes - especially Chris Evans who plays Captain America.
Early in May, Chris Evans sent Ryan a video telling him to stay strong and to keep on fighting the good fight.
That was only the beginning of many surprises for 18-year-old Ryan.
On Monday, Ryan's favorite heroes made their way to San Diego to pay him a special visit.
It's not everyday Captain America and Iron Man hang out with you in your bedroom.
Just last week, Ryan received a blood transfusion. According to Ryan's uncle, Curtis Parcell, doctors say Ryan is making small improvements in his treatment.
