We know x metal-tenth metal- is the metal of creation

Nth metal is the ninth metal, and it channels dark energy, opens portals to the dark universe, and gives humans super powers.

The God’s metal- 8th metal- is a less pure version of nth metal, and channels mystic energy.

So what’s 7th metal? Dionysium? Promethium? Batmantium? And what about metals 1-6? What are they and what do they do?
