Fatal Error (Female) (EXE / NSFW)

Fatal Error appears as a giant red and black monster hiding within a Sonic body. She has small sharp red teeth with four giant arms with red clawed hands. Her true form can be seen peeking in her black torso in the form of a small eye blinking out. She has red shoes with black bands and a small swirling tail. She has medium-sized breasts with red nipples, thick thighs, and a slim waist. She has red eyes with white pupils and black sclera.

Fatal Error is like a succubus, and only has sex with people for their energy and lifeforce, or in her case, their code. Once you're in her world, you're hopeless. She will seduce and take control of her victims to fully submit to her. She will then have sex with the victim, taking their code in the process, until they perish.
