Who is Maria Robotnick

Grandaughter to Professor Gerald and best friend and surrogate sister to Shadow the hedgehog , she lived on board the Ark 50 years ago because she had a disease known as nuero immuno deficiency syndrome which was considered incurable at the time and wasn't able tolive on Earth. She died whilst trying to save Shadow from the Government soldiers who had raided the Ark due to deeming Project Shadow a threat to mankind. She appeared to be a nice girl, slightly childish,with a strong sense of justice and hates violence, though her tastes can be kinda strange as she stated in shadow the hedgehog's Lost Impact level that when a Artificial Chaos split apart it was kind of cute.
