Maria Robotnik

Maria Robotnik (マリア・ロボトニック Maria Robotonikku?) is a fictional character from the Sonic the Hedgehog series. She was a young human, the granddaughter of Gerald Robotnik and the cousin of Dr. Eggman. Born and raised on the Space Colony ARK, Maria suffered from a terminal illness that made her unable to leave the place of her birth and go down to earth. To save Maria, Gerald worked on Project Shadow in hopes of finding a cure for her. Gerald's research produced Shadow the Hedgehog, who Maria became close friends with. When G.U.N. later shut down the ARK, Maria was killed by a G.U.N. Soldier while trying to assist Shadow in his escape from the colony. Her passing had a big impact on Shadow's psyche and proved to be an event that would strongly influence the fate of the world in the decades that followed.

Canon

 * Moriah Angeline (Sonic Adventure 2)
 * Rebecca Honig (Shadow the Hedgehog)

Fanon

 * Angourie Rice (James Cameron's Sonic Cinematic Universe)

Iago PUC's ideas

 * Maria appears in James Cameron's Sonic Cinematic Universe, played by Angourie Rice. She first appears as a spirit in the first film, and in flashbacks of early films, such as Shadow and Rouge.
 * In the Disney+ crossover miniseries Marvel's All-Star Multiverse, there is a character named Maria the Tiger (voiced by Jennifer Hale), who shares the same name and personality as Maria Robotnik, and is depicted as Shadow the Hedgehog's partner and lover.

Joint ideas

 * Maria makes cameos in DC vs. Sega. She appears in endings of Doctor Eggman and Shadow the Hedgehog; both characters mourn hers and Professor Gerald's deaths as her image appears in their minds.
