Maria Robotnik

Maria Robotnik (マリア・ロボトニック) is a character that appears in Sonic X. She was a young Overlander, and the granddaughter of Professor Gerald Robotnik and cousin of Doctor Eggman. She was Shadow the Hedgehog's only close companion.

Anime
Maria was a terminally-ill patient on the Space Colony ARK, who had contracted a disease. During time onboard the ARK, Maria became close friends with Shadow the Hedgehog, the result of Project Shadow. Maria was shot and killed during the invasion of the ARK by GUN, 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 Overlander, 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, it is explained why 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.
