Shadow The Hedgehog

Appearance
Shadow is a Black and Red Hedgehog, with upward pointing spikes akin to Super Sonic.

Mechanic
Shadow will start at the stage and procedurally head towards the right door. When you see him through either the light or the camera, close the door, then when he leaves from the camera at the right door, you can open the door again.

Fun Fact
In the oldest demo of FNaS Reanimated, Shadow would actually appear at a now removed window infront of you, he would stare at you with a menacing grin, soon to leave and do some other shiz.
