Endo B, also known as "Angel", is the first of the four tertiary antagonists of The Joy of Creation: Story Mode, during both Basement and Attic memories, and is a member of The Fallen. He is the main antagonist of 04, and the main antagonist with Endo C "Mouth" as the secondary antagonist in 02 of Basement, and is the second of the tertiary antagonists of Attic, appearing idle in the right hallway of the room before or after a Running Fallen attacks the player.
Endo B "Angel" is a withered endoskeleton based on the FNaF 2 endoskeletons. Its body is covered with loose wires with its left ear is missing, along with seemingly absent eyes and a lack of a lower jaw. Endo B "Angel"'s posture usually has one of its hands covering the area where its eyes should be, while the other hand reaches out as if to find something to lean on. Endo B "Angel"'s Jumpscare has it scream in your face.
The stance Endo B "Angel" commonly takes resembles that of a person who has been recently blinded.
In 04, as the player deduces the two codes of 9632 and 2541 to unlock the gates to reach the key by the stairs, Endo B "Angel" will move towards the player as they turn their face away from him. Notably, he will only attack if the player allows him to approach Michael without facing towards the enemy. The player is completely free to push Endo B "Angel" around on the floor while he is frozen in place by the player staring directly at him. Once the player collects the key, Endo B "Angel" despawns.
In 02, once Ignited Golden Freddy's message ends and the moment he states "HE REMAINS", two Endo B "Angel" clones spawn right behind the left entrance of the gates blocking the player off from the rest of the hallway, one following the other on the player's left. They follow the player around if the player has them off the screen and force them to stay facing in one direction. Once the player reaches the end of the hallway, they find a single button that they must press, the moment they press it causing a third and final clone to spawn in the hallway that the player needs to also remain staring at. Once the player walks up the stairwell and opens the iron grating blocking off the doorway that leads to the real world, all of the clones of Endo B "Angel" disappear completely.
Attic
In the fifth and final memory, Attic, Endo B "Angel" will be one of the four enemies to attack the player directly from the attic area while defending against Creation and Ignited Golden Freddy.
Trivia
Endo B "Angel" is the least damaged out of The Fallen.
Endo B "Angel" is the only member of The Fallen to possess a full set of two arms.
Despite being implied to be the endoskeleton of Ignited Freddy, Endo B "Angel" has hands while Ignited Freddy's arms are missing, and Ignited Freddy still has his eyes.
The nickname 'Angel' is a reference to the Weeping Angels from the British Sci-Fi TV Show Doctor Who, as it's behavior is rather similar.
This is further proven by the hallucination Michael gets in the basement 'DON'T TURN YOUR BACK' and 'DON'T LOOK AWAY'.
According to the majority of the community, Endo B "Angel" is the most difficult of The Fallen to evade.
The Behind the Scenes of Endo B "Angel" show it with its eyes, lower jaw, and ears intact.
Endo B "Angel" can be seen rarely moving, however when it does, there is no animation. He moves while maintaining his paralytic pose. This happened to a well-known Youtuber named Markiplier which can be found here. This is a glitch caused by the fact that Endo B "Angel" was never intended to be seen while moving, so making an animation for that would waste time.
Endo B "Angel" is the only member of The Fallen who does not charge at the player via sprinting, primarily due to his movement mechanic.
Endo B "Angel" is the only member of The Fallen to never be seen nor heard charging the player.
Attic likely makes an exception to this rule, as the player technically stares at Endo B "Angel" via the right attic monitor, meaning he should be paralyzed as long as this occurs. He is not paralyzed when the player stares at him in Attic, however, meaning he charges the player via teleportation into the room.
A fan-game known as Fazbear Entertainment: Chapter 1, released April 27th 2021, features a character known as The Endoskeleton, of whom uses verbatim the same mechanics as Endo B "Angel" as well as maintaining similar positions.
