Taking a role of Alphys, instead of her face being shown, she wears a skeleton mask. She also wear glasses glued to her skeleton mask since she fit while wearing it. She wears a lab coat, and she wears brown shoes.
She is known as a human, but everyone always mistake her as a skeleton everytime. ( Except for Kk. )
Bone has the same personality to Alphys. Shy, Nerdy, Created the Amalgamates, Lies alot, Loves anime, and Depressed. The differences is that she doesn't have a crush on Queen Trash, They made Create to impress her.
