Maria Robotnik (Sonic X)

Maria Robotnik (マリア・ロボトニック) is a character that appears in Sonic X. She was a young human, and the granddaughter of Professor Gerald Robotnik and cousin of Doctor Eggman. She was Shadow the Hedgehog's companion and best friend and the main reason for Shadow's creation.

History
Maria was a terminally-ill patient on the Space Colony ARK, who had contracted a disease. Her grandfather, Professor Gerald Robotnik, created Shadow as a means to study immortality and to use the fruits of the project in an attempt to cure Maria.

After Shadow's creation, he became close friends with Maria to the end. Sadly, Maria was killed during the invasion of the ARK by the Guardian Unit of Nations, after releasing Shadow from a cryogenic tube in the Japanese version. However, in the English dub, they say she was taken away.

Personality
Maria was a very kind individual who always thought about others before herself. This is proven by the fact that after she was shot and was dying, she did not hold any ill will towards the people living on Earth and in her dying breath she requested Shadow to give them a chance for their future and that in doing so they will live very blessed lives and that was the reason that he was created.

Trivia

 * In the Japanese version of Sonic X, it is explained that Maria is in space because her disease is contagious and could be deadly if allowed to spread.
 * Christopher Thorndyke and Molly both remind Shadow of Maria because of their similar selfless natures and the kind, loving look in their eyes.
