Perpetua/Chesstale

Rook2 is the Chesstale version of Perpetua. She is significantly more powerful that the original Perpetua. She is a rook in the game of Chess.

Personality
She is confident, slightly lazy, intelligent and easily pleased. She loves playing chess, and is a very good player, though not as good as Sans. She likes to listen to music, dance and draw. She is incredibly observant if her friends are killed. During the Genocide Route, she is a lot less playful and merciful and more serious and brutal. If she has befriended the protagonist, then they kill Papyrus, as her befriending is before Papyrus's fight, she feels hurt, betrayed and depressed. If Papyrus is killed, by the end of the Neutral Route, she has disappeared without a trace, similar to W. D. Gaster.

Appearance
She has white bones and no hair. Her pupils are white and heart shaped. Her fingers levitate over her hands.

She wears a black hoodie with a lavender circuit design and white attachments, similar to Chesstale Sans's hoodie, a white collared shirt with an upturned collar, purple shorts with a similar design as her hoodie, in black and black boots with purple circuits.

Neutral Route
During the Neutral Route, if Papyrus is killed, she disappears without a trace, similar to Gaster. If you reminded someone about her, they would have no idea what you meant, implying she vanished from the minds and memories of every single monster. Through this, it can be implied she attempted suicide in the CORE, but was shattered across time and space.
