He is a white, shattered rabbit resembling a Springtrap, and palm prints of various colors can be seen all over his body and in the right part of his chest there is a flask with a human heart that continues his miserable existence.

And he was running around the fucking huge catacombs-laboratories that were under a huge shopping center.

Well, it's obvious that I cut out such a strange idea, as well as the main villain, and this location.

And + fan facts:

1) His claw fingers could be syringes.

2) I was never able to determine who he was during his lifetime, but I knew for sure that he was very connected with the restaurant.

3) In the mall itself, he was something like a Mimic in the SB, he could control all the endo skeletons in the building and close the doors in front of the player.

Well, I think I've told you everything important about him.
