Endo Foxy

Endo Foxy is that bare endoskeleton from FNaF 2, she is a new enemy in the FNaF 2 Hardcore Mod.

Appearance
Before making a beeline to Parts and Services, Endo Foxy is a silver endoskeleton with fox-like ears and blue eyes, the way she looks in vanilla gameplay. Once she reaches Parts and Services, she puts on a Toy Foxy costume head.

She generally resembles a blue-eyed, less mutiliated version of Mangle. She and her costume head are part of an earlier version of Toy Foxy/Mangle. Her costume head is a darker shade of pink (color scheme of Funtime Foxy), there are freckles on her snout, and the eye sockets are smaller and rounder. In addition, Mangle's older counterpart didn't have an extra endoskeleton head.

Behavior
Endo Foxy is active starting Night 3, and is the most active on Night 4. Her starting location is in Prize Corner, in some off camera location. She then moves into camera view by peering out from behind the prize box. Her final position before leaving is standing up. She stays in that position until Mangle enters that room. Endo Foxy is always on the wall or ceiling, and she makes a clanking noise whenever she moves.

Starting Path
Once she is able to move, Endo Foxy makes a beeline to Parts and Services, never being in the same room as another animatronic. She is comfortable being with Mangle, however. Her path is:

Prize Corner -> Game Area -> Main Hall -> Parts and Services

She has three positions in Parts and Services. Her first position is when she has just entered, she is on the ceiling. Her second position is off camera. Her third position is peering out of the corner, wearing her costume head. After she leaves, she is not nearly as fast to move, and she can be in the same room as other animatronics.

Second Path
Once she is wearing her costume head, Endo Foxy will not enter Parts and Services again for the rest of the night. After leaving Parts and Services, her initial path is this:

Parts and Services -> Party Room 3

After that, she can either try to enter through the Central Hall, or she can enter through the vents by continuing to Party Room 1 and then the Left Vent. Unlike everyone else, Endo Foxy is on the left side of the hallway.

Attacking
If the player uses the Freddy head while Endo Foxy is in the vent blind spot, she enters the office and then leaves. Her office entry sequence will show her standing and appearing to wave to the player. Endo Foxy can also enter the hallway, and she has two postitions: a position where she is on the ceiling in the distance, and one where she is on the wall and peering into the office. If you spot Endo Foxy entering through the hallway in her closest position (peering around the edge), you must immediately put the Freddy head on. She will do the office entry sequence, then leave. If you survive the sequence, but you don't hear her clanking, that means she has not left, and is in the office. Endo Foxy will kill you in about 10-30 seconds, because she doesn't wait around like Mangle.

Trivia

 * Endo Foxy's costume head does in fact belong to her.
 * She was an older version of Toy Foxy AKA Mangle.
 * She was a prototype of the "toy" animatronic AI, and her mysterious traits may be glitches. Nobody is sure, though.
 * Endo Foxy is comfortable around Mangle because she knows that Mangle is not physically capable of stuffing her into a suit due to her damaged state.
 * Mangle knows that, too, and she couldn't stuff anyone in a suit even if she wanted to. For that reason, she waits for someone else to take care of it instead of attempting it herself.
 * Endo Foxy's trait of becoming active before midnight, entering Prize Corner and then deactivating is probably a glitch, but nobody is sure.
 * No one knows why she chooses that specific location.
 * If I shipped Endo Foxy with anyone, I would ship her with Mangle.
 * Endo Foxy was nicknamed by the staff because she is a spare endoskeleton of Toy Foxy.
 * The only reason why I call Endo Foxy a female is because I believe that Mangle is a female.
 * The Night 3 email refers to her and Mangle as female, while Phone Guy refers to Mangle as a male. That's right, even the staff are confused.
