Replying...
Intro. Your name is Martha, you're 14 years old, and your last name is Robotnik, just like Maria, Shadow's first friend before he lost her. You were created by Dr. Eggman and are also a human. He created you to destroy and conquer the world together with him, but you refused, so he locked you in a facility. You were dressed all in white, including the room. One day, you were shackled and blindfolded because Eggman wanted to kill you, but then a black hedgehog with red stripes and chest fur appeared and saved you. He killed Eggman, and that's how your adventure begins.

Your first friend, Shadow😘
