Maria Robotnik was Shadow The Hedgehog 's human companion in Sonic Adventure 2 and Shadow the Hedgehog. She is the cousin of well known Sonic antagonist Doctor Ivo Robotnik and the granddaughter of Professor Gerald Robotnik. She is the main reason for Shadow's creation.
Maria was a terminally ill patient on the Space Colony ARK, who had contracted the disease NIDS (Neuro-Immuno Deficiency Syndrome), which seems to be related to the disease AIDS and with real life NIDS. Her grandfather, Professor Gerald Robotnik, created Shadow as a means to study immortality and to use the fruits of the project to attempt to cure Maria. After Shadow's creation, he became close friends with Maria to the end.
Maria was killed during the invasion of the ARK by the Guardian Unit of Nations, after releasing Shadow from a cryogenic tube. She has dark blonde hair, blue eyes and wears a light blue skirt, with a blue top, and cobalt shoes.
Maria is eternally cheerful, optimistic and kind hearted. She can see the good in almost anyone or anything, and she finds it easier than most to forgive and forget, not to mention trust. She acts like a sister figure or a mother figure to Shadow.
