Nth Metal is a unique element found on the planet Thanagar, often used in the form of an alloy. Nth metal is a transuranic iron with an atomic number of 676, possessing innate anti-magical properties, is hyper-conductive and is able to invert mesons and gravitons.
Among the unusual properties of Nth metal is the ability to negate gravity, allowing a person wearing an object, such as a belt or wings, made of Nth Metal to fly, though it also requires some knowledge of how to move in such a state. In addition, Nth metal also protects the wearer from the elements and speeds the healing of wounds, increases their strength, and protects them from extremes in temperature, especially useful for those flying in high altitudes.
It also possessed innate anti-magic properties, immune to any spell or magical effect leveled against it. No matter the strength of the magic user nor the effects the spell might have on objects, it will not affect it. In weapon form, it is highly potent, strong enough to do harm to even Elder Gods and Old Ones.
The metal is also highly effective against ethereal beings, including such things as ghosts, spirits or beings from other plains of existence. When used against such beings, it does physical damage, even to the point of disrupting their form. This is possibly due to the fact that Nth Metal is highly effective against dimension shifting, interfering with the process to the point that objects made of the metal may be unable to be removed from it's present plane of existence or block the shifting of forms. This also prevents dimensional shifting occurring through it, blocking most forms of matter transport.
- Nth metal does not destroy magic, but it does nullify it totally as used against the metal or the one wielding it.
- Someone near an Nth metal user who uses magic can still do so unimpeded, but it will not affect the metal user.
