Rubies

Rubies are common soldier Gems that is used by Homeworld, usually for bodyguarding. Rubies are commonly put together with other Rubies since they work great in pairs with other gems, but not alone.

Role
Rubies are a type of soldier caste. They are described as "common", seeing as they are all originally identical to one another. They appear to be used as personal escorts and bodyguards for high-ranking Gems; typically Sapphires. Rubies are considered somewhat unimportant and highly expendable grunts, though they compensate by fusing together into bigger constructs of themselves. Rubies are also sent to different planets to seek out specific Gems.

As common soldiers, Rubies are not very intelligent. Their main strength on Homeworld is their ability to combine; a Ruby would never be sent alone to do anything. Rubies are not supposed to have different personalities; the fact that they do "flies under the radar" because they act serious around higher-ranking Gems.

Physical Characteristics
Rubies are short in size with boxy body shapes and large square-shaped afro-like hair. While they can have slightly different shades of skin tone and hair color, they have no other real physical differences between them.

Most Homeworld Rubies serving Yellow Diamond wear the standard uniform, although their has been exceptions. Some Homeworld Rubies wear very basic uniforms with no clear insignia on them.
