X-45

X-45 also known as The rebound girl. She's very hostile, faster then X-15 and extremely dangerous. She'll arrive when the lights flickered, spawn at door 0 and starts rushing towards the room you're at. She's very fast and no one can outrun her. Ones she's hits the wall, she'll rebound meaning she's return back all the way to door 0. She makes a different noise then X-15, different speed and different abilities. She can also get rid of by using the crucifix at her. (Any gender and during your run, the lights flickered but then time the noise is different from X-15)
