Vibranium () is a fictional metal appearing in American comic books published by Marvel Comics, noted for its extraordinary abilities to absorb, store and release large amounts of kinetic energy. Mined only in Wakanda, the metal is associated with Black Panther, who wears a suit of vibranium and Captain America, who bears a vibranium/steel alloy shield. An alternate isomer of the material known as Antarctic Vibranium or Anti-Metal has appeared in the Savage Land. Publication history 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 Comics 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 known metal. 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". Fictional history In the Marvel Universe, vibranium was first deposited on Earth by a meteorite 10,000 years ago. In the comics, the first documented discovery of vibranium was during a human expedition to Antarctica. This particular isotope of vibranium was called "Anti-Metal" due to its property of dissolving other metals. In the comics, a different variety of vibranium found in Wakanda absorbs sound waves and other vibrations, including kinetic energy. Absorbing sound waves, vibrations, and kinetic energy makes this metal stronger. To protect this resource, Wakandans concealed their country from the outside world. Wakandan king T'Chaka funded his country's education by occasionally selling off minuscule quantities of the metal. As a result, Wakanda is one of the world's most technologically advanced nations. During the early 1940s, a small amount of Wakandan vibranium came into the possession of the scientist Myron MacLain. He tried to combine vibranium with iron to form a new tank armor, but was unable to fuse the elements. One morning, he found that the two materials had bonded
