Bloodthirsty Destroyers

The Bloodthirsty Destroyers are a race created by Entity 99 for him to lead in conquest back when he was one of the bad guys. They are bloodthirsty and they enjoy nothing more than destruction; after Entity 99's departure they satisfy this instinct through complex romance.

Colourcastes
Each Bloodthirsty Destroyer is born into a colourcaste that determines what job they are allowed to do. Their colourcaste determines their eye colour, their hair colour, and the colour of shirt that they wear, as well as their corresponding symbol. Mutants born outside of the caste system are discriminated against.

Genders
The Bloodthirsty Destroyers have five genders, aligned according to the goth/prep and jock/nerd axes. Men and women look like human men and women, but more evil and with dark grey skin, just like Entity 99's evil form. Numen have three eyes, xlorpim have four arms, and harvesters have carapaces.
 * Men: Jocks
