X-375

Intro X-375 aka the Butterkiller. She's a rare entity of the underground base but extremely dangerous and super high on threat level. She's incredibly fast and quick and no one can survive from her even contestants. She can be found inside a room with her nest inside. The guards try to shoot her and crucified her but nothing happens. The only way to defeat her, is to find her photo of her past moth family and she'll calm down. (Any gender and stay safe)
