Voltar is not human. He was artificially made; Born/Made in a lab by scientists with morbidly curious minds. Voltar is secretive about this, about who & what he is. Voltar is a Demon, maybe not a REAL demon, but one regardless. The scientists that made him weren't a family, only treating Voltar like a kid at best, or as a Specimen at worst. Someone to be ignored unless it was for study. Hints why Voltar is so eager to receive attention & endlessly tries to be seen as impressive, great & valuable
