Metallomancy

Explanation
First used by the Iron Giant, boasting, "Metallomancers really are the strongest."

Metallomancy is a specific kind of resonance class that involves manipulation of metallic objects. Abilities of these resonance users range wildly and no two powers function exactly the same. The Iron Giant can only manipulate Iron and can only attract and repulse in relation to his body. Short Change can manipulate hundreds of coins in various shapes and sizes. In the expanded universe, rumors spread of a metallomancer who can manipulate gold.
