Astran

The Astrans are a hairless, humanoid race which possess yellow skin and toe-less, spatulate (flat) feet. They have developed four lungs and a special excretory gland in their stomach. In a similar fashion to the Human mutant Magneto, they are capable of controlling metal, likely caused by their planet's surface being composed of 50% metal (with 25% dedicated to water and the rest dedicated to soil). The Astran planetary government is theocractic, while three-quarters of the populace are either priests or artists.

Trivia

 * The Astrans first appeared in The Incredible Hulk #6 (March 1963), when The Metal Master tried to invade Earth.
