Endo-Headless

Endo-Headless is one of the first Characters who appear in the series.

Background
Endo-Headless is a prototype endoskeleton, who never was finished, as the head never fully worked when the creators tried, but every single time it broke off, so it was scrapped along with other Endos. Like the others, while it was stored away, it remained active.

Appearance
Endo-Headless has the upper portion of the head entirely missing, while the jaw remains, but wires hang from the jaw. The build of Endo-Headless appears very bulky compared to most of the others, with bigger feet, large wrists and hands, and more squared off joints. Some parts never were finished, leaving parts looking bare.

Role In Story
Endo-Headless appearing as one of the first Characters in the series shows it was not approved to preform or be used, but was stored away just in case something could be done later with it, but nothing ever did.

Office Duty
Endo-Headless is shown on a monitor, and when that goes static, you must hold down 1 to prevent the attack, as Endo-Headless won't be able to find you if you stay still, thus you make no noise for it to hear, and it can't see at all.

FredBear's: Old Memories
Endo-Headless appears in the memory "Endos of the Past" and sits behind the player. If Headless is seen sitting up-right, the player must use the shock pad to make them go back to a passive state.

FredBear's Ultimate Custom Night
Endo-Headless will be heard running at random during the night. If you hear their metal footsteps, you must look at the front of the office and hold 1 to not die.

Endo-Skeleton Ultimate Custom Night
Endo-Headless works near identical to his other Custom Night appearance, but the player can hold 1 anywhere, so long as they are looking inside the office while doing so.

Trivia

 * Endo-Headless was the first character to be missing any part of their body
 * Endo-Headless is one of the characters who went through a major re-design, possibly the biggest one
 * Despite being called Endo-Headless, he still has his lower jaw, meaning he isn't entirely headless
 * Although, in some games like Office Duty, this is not the case, and he just has a neck with wires coming out
 * He is shorter than most of the regular Endos, due to his upper head/entire head being missing
 * The height stated on this wiki is the most recent model's height, according to the developer
 * The model with the whole head missing is likely around 4.6ft to 4.8ft
 * Unlike most of the others, his joints are not round, but square
 * This is likely what makes him seem more bulky than the others
