Vibranium

a rare, naturally occurring meteoric ore, theorized to be extraterrestrial origin, that has been found in two distinct varieties.

Vibranium is not as hard or dense as Adamantium, but it is still very durable. It is also easier to make objects out of, such as the mesh costume the Black Panther wears.Vibranium absorbs more impact than adamantium.

Wakandan Vibranium is found almost exclusively in the tiny African nation of Wakanda. Wakandan Vibranium, through as yet unknown means, absorbs vibratory energy in its vicinity, such as sound waves, within itself. The apparent observable vibratory rate of the molecules of the Vibranium itself does not noticeably increase when the Vibranium absorbs mechanical energy. The outside vibratory energy is stored within the bonds between the molecules making up the Vibranium. As a result, a chunk of Vibranium which had absorbed a considerable amount of vibratory energy would be exceedingly hard to demolish. If enough force were were applied to this chunk to smash it, the Vibranium would explode, releasing much of the absorbed energy. There are limits to the capacity of Vibranium to absorb vibratory energy, although the exact extent of these limits has not yet been determined.

Antarctic Vibranium has thus far been found in nature only in the isolated region of Antarctica known as the Savage Land. Antarctic Vibranium, is also known as Anti-Metal due to its effects. Whereas Wakandan Vibranium absorbs vibratory energy into its molecular bonds, Antarctic Vibranium, through a means that is not yet understood, emanates vibrations which cause the atomic and molecular bonds in nearby metals of other kinds to weaken. The result is to cause nearby solid metals to liquify. If huge quantities of Antarctic Vibranium were gathered together, at some unknown point the accumulated mass would increase logarithmically as more Vibranium was added.

Theoretically, if the enormous mound of of Wakandan Vibranium were composed of Antarctic Vibranium instead, the resulting vibrations would therefore liquify metals throughout Africa, and possibly beyond. A fraction of the sacred mound of Wakandan Vibranium was apparently converted to Antarctic Vibranium by particle bombardment. It is not known what the Wakandans have done with the artificially created Antarctic Vibranium.

It is possible to convert Vibranium into Anti-Metal, but it is unknown if the opposite is true.

Reverbium is an artificial variant to Vibranium created by Sanjani Jaffrey, after most of the world's Vibranium was rendered inert. This variant is imperfect, so rather than absorbing vibrations, it does the opposite, and blows everything away, making it a powerful weapon even in small amounts. Reverbium seems to have recently been destroyed, to avoid its use as a dangerous weapon, after The Hobgoblin stole some of it for the Kingpin.
