Captain America appeared in comics for the next few years, changing from World War II-era hero fighting the Nazis to confronting the United States' newest enemy, Communism. The revival of the character in the mid-1950s was short-lived, and events during that time period are later retconned to show that multiple people operated using the code name to explain the changes in the character. These post World War II successors are listed as William Naslund and Jeffrey Mace. They are assisted by Fred Davis continuing the role of Bucky.
