Maria Robotnik the Hedgehog

Maria Robotnik was a human since 50 years ago but couldn't live on Earth because of her NiDS disease. She stayed on Space Colony Ark with her grandfather, Gerald Robotnik, and Shadow the Hedgehog. But her lift was short when she was gunned down n by a GUN agent. Everyone including Shadow thought she was dead, however it has stated that she was really in cryogenic sleep and her body was combined to Shadow's abilities.

Maria made her debut return on the 2015 game Sonic Adventure 3, as a hedgehog. She becomes the ally of Sonic and the gang and love interest of Shadow the Hedgehog.
