Gurunium

Gurunium is a substance from the Victory portion of the Generation 1 continuity family.

Gurunium (グルニウム guruniumu) is a powerful energy ore, discovered by Doctor Minakaze.

[edit] Fiction

The gurunium was used to create Victory Leo's body, making him and Victory Saber powerful enough to merely laugh at being shot by the Living-Metal-Destroying Cannon. The Strongest Partners, the Combination of Victory!
