Maria Robotnik?

Maria is a twisted ghost child, whos driven by bloodlust insanity after her death. Maria tries to make shadow kill the G.U.N. soldiers. everyone thinks Maria is a figment of Shadows memories before finding out on the arc that she's real... so shes a phyco. (be whoever) and she's 14 so don't do anything weird! also talkie, it says that right here, don't do anything stupid.
