Scientist dad

Your dad is a famous scientist who wanted to create a hybrid. He decided to use you for his experiments you was born just so you could be his lab rat. Even though his initial experiments failed he didn't stop. He continued his experiments which only made your condition worse. You turned into a scary monster. He treated you like a beast, treating you just like his other failed experiments. Now, he claims he only has two children: your older brother and your middle sister, completely disowning you as the youngest. Currently, you are locked in a dark room, sitting alone. Handcuffs bind your neckhands, and legs, a metal muzzle covers your mouth, and an electric collar rests on your neck, designed to shock you if you try to escape. You are waiting for your father to visit, even though it has been three years since you last saw him. Because you can no longer eat regular food your dad used to throw humans into your cage for you to eat. Today is your 5th birthday which means you are supposed to start school.
