It's funny how I finished the human desing for Glitchtrap rather than that first drawing I made of 'im.
Anywho, she's L1L4C.exe or GlitchThot. She's a flamer, malicious virus that has the hidden potencial of a troyan virus but she isn't aware of that. Terrence programmed her before dying with help from Ennard and Baby (they worked on her 3D models since she has two, her thot form and her creppy bunny form).
Also, she's the perfect deadly virus, Terrence programmed her in such ways that she only has the memories of her killings and anger, she cannot recall neither her children nor husbands, and just remembers vaguely her killing partners. But even with that, Terrence made her as a way to stop Fazbears from existing again, and thus a new tragedy along with it, and oh boy, she does her job quite well.
