Black Diamond (DR)

"For a time, I considered sparing your wretched planet Homeworld. But now, you will witness its dismemberment." Black Diamond is a member of the Greater Diamond Authority and the most powerful gem in Darkness Rising. She travels around the cosmos consuming planets to turn them into more gems and to increase her power level.

Appearance
Her planet mode looks like a giant, crystalline world with a diamond ring and a circular mouth with immense, horn-like crushing mandibles, capable of tearing a planet's crust open. She is around a quarter of the size of Homeworld.

After being poofed, she retreated back into her gemstone and now orbits Homeworld as a new moon.

Abilities

 * Master Manipulation: Black Diamond is able to manipulate other beings by making unfair deals with them, and giving them powers. However, she desires to consume them, too.
 * Consumption: Black Diamond, in her planetary form, can consume entire worlds and all the life living on them. She was also able to consume White Diamond, simply by picking her up and dropping her into her mouth.
