Endo-FredBear

Endo-FredBear is, as the name implies, FredBear's Endoskeleton.

Background
Endo-FredBear is, as his name suggests, the endoskeleton of FredBear, a golden Bear animatronic from FredBear's Family Diner. He is the insides that have been taken out to make room for a human to fit inside FredBear, but he remains active still, despite being out the suit.

Apperance
Endo-FredBear has a large head, with a constant smile. His ears are missing some bits of it, and his fingers also are missing it seems. He has bulky frame like Endo-Headless, being square. He also has a type of frame to keep him stable, due to his heavy weight, as to make him not fall apart. He also lacks his left eye. He does have a hat, but it seems that paint on it came off, and it is now showing metal.

Role In Story
Endo-FredBear was made to obviously fill in FredBear when a worker couldn't wear the suit, but after the place shut down, Endo-FredBear was moved to some different locations as a result of this, but he always would find a person who was "Trespassing" as his programming made him always assume he is in FredBear's diner, thus at night he attacks people who trespass.

FredBear's Old Location
Endo-FredBear comes from the hallway, and you must cover your face with a newspaper to avoid him, as turning the lights off won't work on him.

FredBear's Ultimate Custom Night
Endo-FredBear appears as a plushie on the player's desk when he is active. He periodically has his eyes glow, and requires you to honk his nose to prevent his attack when you see the eyes glow.
