{{merge|Captain America|date=December 2023}} {{no sources|date=December 2023}} [[File:CapShield05.jpg|thumb|The circular design of Captain America's shield: a white five-pointed star on a blue circle surrounded by three concentric rings of red, white, and red.]] '''Captain America's shield''' is a fictional item appearing in American comic books published by [[Marvel Comics]]. It is the primary defensive and offensive piece of equipment used by [[Captain America]], and is intended to be an emblem of [[United States|American culture]]. The most well-known of his shields is a disc-shaped object with a five-pointed star design in its center, within blue, red, and white concentric circles. This shield is composed of a unique combination of Vibranium, steel alloy, and a third catalyst that has never been duplicated called Proto-Adamantium. It is virtually indestructible. It is as much an offensive weapon as a defensive one for Captain America. Cap uses it against his enemies, mainly, by throwing it at them and can perform mind-bogglingly impossible tricks with it. Over the years, Captain America has used several shields of varying composition and design. His original heater shield first appeared in ''Captain America Comics'' #1 (March 1941), published by Marvel's 1940s predecessor, Timely Comics. The circular shield best associated with the character debuted in the next issue, ''Captain America Comics'' #2. [[Category:Marvel Comics]]
