Vibranium is a fictional metal appearing in American comic books published by Marvel Comics. It is most commonly known as one of the materials used to construct Captain America's shield, but it is also noted for its connection to the Black Panther and his native homeland of Wakanda (a fictional country in Africa).
Vibranium first appeared in Daredevil #13 (February 1966), which was written by Stan Lee and illustrated by John Romita. Here, vibranium was seen to be an unusual metallic element with decidedly strange properties. Since that point in Marvel continuity, it has been established that there are a few variations of this element which can be found in isolated regions all around the world. The variation first introduced in Daredevil #13 eventually became known as Anti-Metal. This variation's unique attribute is that it can cut through any metal known to man. In the Marvel Universe, Anti-Metal can traditionally be found only in Antarctica. Later in Fantastic Four #53 (August 1966), by Stan Lee and Jack Kirby, a new variation of vibranium was introduced in the isolated nation of Wakanda. This variation had the unique attribute of being able to absorb sound. This is the variation which is most often identified in continuity as simply "vibranium".
