Promethium (Metal)

Promethium is the name given to two metal alloys: "Depleted" and "Volatile" Promethium.

Depleted Promethium

Depleted promethium was invented and patented by Steve Dayton of Dayton Industries.

When alloyed with titanium and vanadium, it forms a near-invulnerable metal. Though not on par with Adamantium

Volatile Promethium

Promethium is also capable of generating and absorbing near-limitless amounts of energy, and so can be used as a power source for many gadgets. However, this "volatile promethium" is a dangerous mutagen that can be used to mutate living beings or trigger their metagene.
