Maria Robotnik was among those that were killed the day on ARK when the military force GUN stormed the space colony and killed and arrested those on the colony. At the time before the raid she was Shadow's first and only friend. At the time of her death before she released Shadow's pod toward Earth she made him promise her one thing: "Let the people of Earth have a chance to be happy." those were the last words she would ever speak to Shadow before she died. Needless to say, Shadow hated GUN for killing her and deeply misses her. Maria is Eggman's cousin and the granddaughter of Gerald Robotnik.
First appearence in Sonic Adventure 2Dr.Ivan Robotnik (or as we call him Eggman) has been Sonic's nemesis for as long as anyone can remember. Eggman desires nothing more than to make his own Empire and take over the world. He loathes Sonic with every fiber of his fat being and will stop at nothing to try to stop that Hedgehog from foiling his plans once and for all! Of course, this never happens. Eggman has an I.Q of 300 and STILL calls himself a scientific genius. The day he takes over the world will most likely never come.
