Emerald

Emerald is a Homeworld Gem who made her debut in "Lars of the Stars", and she is shown to become very agitated when the Off Colors had crashed her personal ship, impersonated imperial officers, and stole her prized ship, the Sun Incinerator. Her agitation turned into sheer anger when the Off Colors made fun of her, prompting her to openly yell at them through the Sun Incinerator's communicator. She valued her Sun Incinerator too highly to destroy it even when doing so would have dealt with the Off Colors in a single stroke.
