Ophionium

Ophionium (オピーオーンイウム, Opīōniumu) is a newly discovered, rare man-made artificial alloy that is primarily found on a parallel universe; which exist ahead of time when compared to the mainstream continuity universe, and as such, has no direct parallels; due to lack of such technology to create such an artificial superalloy. It is primarily made from proto-diridium, a highly radioactive isotope of promethium and lithesium. It is a dangerous, highly dense, corrosion resistant, antiferromagnetic, high end metal with an extremely high melting point and very low freezing point that has been further enhanced through ethernano treatment.
