The ancient Greek writer Plato referred to ' orichalcum' (Greek for 'mountain bronze') in his description of Atlantis. Thunderbolt Iron is especially popular in fiction (and has some basis in reality-until blast furnaces were invented it was the best source of refined iron).įollowing this would be medical and/or chemical wish-fulfillers Classical real-world alchemy casually referred to carmot, the base substance of the Philosopher's Stone, and Azoth, either the 'universal medicine' or 'universal solvent'. Materials such as Mithril, adamantium and Orichalcum (and all variant spellings thereof) are the fantasy version. The most common varieties of unobtainium in fiction sit somewhere in the middle, like materials so resistant to heat and/or damage as to be Nigh Invulnerable compared to other, similar substances. Others are more fantastic 'high-grade' unobtainium, such as Antimatter, which would be a revolutionary way of storing huge amounts of energy, if it didn't violently undergo mutual annihilation with any conventional matter it came into contact with, including the walls of antimatter storage containers. Some forms of unobtainium are based on real physics, but beyond the current scope of human engineering, such as Room temperature superconductors they would revolutionize just about every form of technology, but they are not in and of themselves dangerous or based on some exotic physics-bending principle.

Alien spaceships and weapons are usually made from unobtainium as well. Much mad science uses unobtainium, such as imaginary chemicals with impossible properties or super-strong alloys that cannot be made from common earthly metals.

Unobtainium is the exotic metal or other material that is needed to make the Applied Phlebotinum work.
