Captain America took some time off from fighting the bad guys to visit sick kids battling cancer in Boston.
Actor Chris Evans, a Boston native, visited with Kenny Botting, who underwent surgery in September for a brain tumor.
The nine-year-old is a big Captain America fan and was super happy and surprised by the visit.
Kenny has been staying at Christophers Haven, which is a home away from home next to the hospital for children with cancer.
"It's their strength that gives people like me strength," Evans offered. "If there is anyway you can bring a smile or give positive words with reinforcement and encouragement, it's worth it."
