Obsidian is a Gem created by Lenhi.


Obsidian is a very stubborn and cunning Gem. She lacks faith in herself but does her best to stay strong in the face of danger for the sake of others.


Obsidian is a Gem with an average slender build and dark grey-toned skin. She has white, slightly-waved hair that is swirled to the side with her bangs covering the right-side of her face. She only has one eye which is a dull purple color.

She currently wears a sleeveless tunic composed of black and white. Over it she wears a short black jacket. It has a diamond-shaped opening to reveal her gemstone. Underneath she wears uneven black leggings with a black band around her left thigh. On her arms she wears a pair of black bands and black elbow gloves that cut-off at her fingers. For footwear, she wears knee-high black boots with white soles. Unlike past forms, her hair is now shorter and in a bun.


Obsidian possesses standard Gem abilities and traits.
