The silly idiot I use to represent myself. She is known as S0na-V, but her actual name is Velvet Lastname. (Well to be specific, S0na-V is the name of the robot suit and Velvet is a being inside of the suit that controls it.)

Velvet's real form is a shapeshifting mass of computer data that's always pitch black with red and purple accents.

Her lore is a bit complicated, but in summary she was created to be a robotic replica of the real Velvet Lastname, who built S0na-V shortly before her own death to replace her.
