in Wakanda, where the resulting explosion could destroy the world. With the unwitting aid of the villain Klaw, Captain America was able to stop the cancer and restore his shield. Properties and known abilities In the Marvel Comics Universe, vibranium is a rare metallic substance of extraterrestrial origin. It exists in many forms: Wakandan variety Wakandan Vibranium is the most common variety, and is often referred to simply as "vibranium". It is a rare substance native only to the fictional small African nation of Wakanda. The Wakandan isotope possesses the ability to absorb all vibrations in the vicinity as well as kinetic energy directed at it. The energy absorbed is stored within the bonds between the molecules that make up the substance. As a result, kinetic energy is dissipated within the bonds instead. There are limits to the capacity of the energy that can be stored, and although the exact limitations are not yet known, there have been a few examples. One such instance was when the Roxxon Energy Corporation discovered that a small island in the South Atlantic had a foundation composed of vibranium. Due to this, Roxxon found it necessary to destroy the island with explosives. Unable to absorb the force of the explosions, the vibranium was destroyed, but it succeeded in entirely absorbing the sound made by the explosion, preventing damage to the surrounding area. This variety of vibranium is also a powerful mutagen. Vibranium exposure led to the mutation of many Wakandan natives. Its radiation has also permeated much of Wakanda's flora and fauna, including the Heart-Shaped Herb eaten by members of the Black Panther Tribe and the flesh of the White Gorilla eaten by the members of the White Gorilla Tribe. Both give superhuman abilities to whoever eats them. It is also believed to dramatically enhance mystical energies. Antarctic variety Better known as Anti-Metal, this isotope is native to the Savage Land. The variation produces vibrations of a specific wavelength that break down the molecular bonds in other metals, causing them to liquefy. It was first discovered by the famous explorer named Robert Plunder; the father of Kevin and Parnival Plunder during his initial jaunt in the primordial environment untouched by time. His more villainous son, who went on to become The Plunderer, would seek to find his father who dubbed the Plunder Stone and all recorded knowledge of the family relic only accessible through
