Maria

This character shares a striking resemblance to Jo, as both were artificially created beings. Driven by a desire to harm Jo, she attempted to take Meg, eventually revealing herself to be Jo's sister. Their combined energies possess the ability to breach alternate realities during conflicts. After Jo overcame her, she relinquished her aggressive nature, regaining her humanity to protect Jo and Meg from the RAPT forces before being killed by RAPT Cybots.
