''Really evil and mischievous doppelganger of a really nice Gem who is seeking to make more Gems victim to her teeth collection.'' 

- Amethyst_Wereraven

Basically, this malicious Gem is hard to see in the darkness she loves and she will attack anything and everything just 'cause she feels like it. She can shape-shift into evil versions of whoever she wants to, and her 'Origin Gem' means she's often nigh impossible to fend off though she will flee if she feels like she's outnumbered. She's emotionless, and often rather frightening when encountered. You generally only see her glowing eyes. Can use Origin Shards.

Her shiny teeth are not candy. Their gem shards that she's fashioned into teeth.
