Captain America

Captain America was a fictional superhero.

History
Captain America was a "skinny little guy" who later became a hero. The Twelfth Doctor claimed this showed how being a hero could happen to anyone. One of the villains fought by Captain America was the Red Skull. The Doctor believed all he needed to win in a fight with Batman was his shield and his wits. Maxwell Collins argued that Batman would win instead. (COMIC: Moving In)

Grant had a poster of Captain America on the door of his childhood bedroom, as well as another poster next to the window depicting him next to Wolverine. (TV: The Return of Doctor Mysterio)
