I'm going to make this as short and concise as possible.

1- Final Roster

The characters are:

Freddy Fazbear

Bonnie

Chica

Foxy

Yellow Bear (sorry fans of the re-colored bear. Its relevance would be very little/none in these games.)

Endo-01 (Fun fact, both Endoskeletons in both games are afraid of having a suit put on them. Plus they know they are in a video game.)

Mr. Carl The Cupcake

Phone Guy

Fixed Foxy

Wolf (Character inspired by the discarded content of FNAF 1 + Wolf from Twisted Ones. His lore is that he was going to be a 5th animatronic in the restaurant that never went beyond a concept)

El Chip (Reference that there was going to be an animatronic beaver in FNAF 1... In this universe he existed since 1993 in a restaurant in Mexico with Catrina Toy Chica.)

Bear5 (Not canon, he was going to be unlocked at some point without the player knowing.)

Purple Freddy (Shadow Freddy from Follow Me.)

Sparky (another option for the restaurant's 5th animatronic but this one was deactivated and abandoned.)

Emerald Freddy (Canon, It is an entity that is the embodiment of the negativity around the 93 location... It is also conscious of the player.)

Stuffed Freddy (Phone Guy had a rough night.)

Fredbear

Springbonnie

Fredtrap

Withered Cakebear

I will explain these last 4 in the history section.

2- History.

2.1- Michael Afton. (FoxyBro)

Basically this game was going to be the correct start to the story. We would play as Michael Afton. (Foxybro.) which in the first week of the game the same story as FNAF 1, but week 2 would basically be Michael having dreams where he relived the work week at the restaurant in '93, however on night 6 no one would be active. .. He would see what the Saferoom was hiding (this was going to be an unlockable camera. [something similar to Shadow Candy's camera from FNAC:R])

He would meet the 83´ Fredbear (The OG), Springbonnie (He doesn't have William's corpse because it hasn't happened yet.), Stuffed Freddy (The Phoneguy) and FredTrap (an employee of Fredbears & Friends. [Location where the incident of "The multiple springlock failure."...specifically the only victim of that incident.])

After surviving that nightmare, Mike closes his eyes... but he opens them and is still in the nightmare.

He ends up facing the first "Boss" character of these games. N1GHTB34R. After facing this being, Mike, barely able to survive, decides to look for answers about his past and what really happened in Fredbears.

2.2- Old Man Consequences

In the "10 years" mode, once you reach night 14, a cinematic where THE PLAYER would be speaking in a point and click free roam environment with Old Man Consequence. The dialogue in summary would serve to unlock the Bossfight against N1GHTB34R but also to begin the player's interference with the story. (something that would be common in these games.)

As a last piece of information, OMC is a Flipside entity that has the ability to bring people from other planes of the FNAF universe to its lake. (and for obvious reasons, to Flipside.)

2.3- N1GHT34R

N1GHT34R is originally an animatronic from Fredbears Family Dinner. Being in a setting apart from Fredbear, Springbonnie and Cakebear.

The animatronic at that time was known as Dreambear, an animatronic who told stories to children. His lore within the character is that he is the father of Fredbear, Cakebear and Springbonnie (adopted.)

Unfortunately he would cause the bite of '83. In this universe the Criying Child (named Garret Warren Afton Schmidt) who hated and feared the animatronic. Garret ended up possessing Dreambear and being locked in the depths of a factory to never see the light of day... But, His anger after dying on his birthday, because of his brother and possessing the character he hated, made him able to manipulate the animatronics of Fredbears Family Dinner and as time passed he decided to go in search of returning the "favor" to Mike and his friends.

During FNAF 1 TDD and FNAF 2 CGR the nightmares we see (the nights) are caused by N1GHTB34R

It is worth mentioning that after "The Big Bite" Fredbears Family Dinner closed to reopen as Fredbear and Friends where Fredbear was discarded for a redesign called SpringFreddy (Lore in the character is that he is Fredbear's cousin.) and add more cast of characters. (The Unnightmare versions of the FNAF 4 animatronics that were Springlocks from the classic 4...)

I'm not going to explain more because this will last 3 hours.

Probably in the future I will make a video explaining all the lore of these games. (Believe me, this is basically FNAF but more.)

and as you will notice, I added several unofficial characters or characters from old fandom beliefs. This is because these games were to celebrate FNAF as a whole. These characters were part of our childhoods in a certain way and I wanted to include them all in a single story. Where originally canon, Non-canon, Official, Unofficial can coexist to celebrate what we all love... FNAF.

Well, that's all that's important. Below I will mainly show images of the content made from the game.

3- Images.

4- Bonus (N1GHTB34R render)

original base model by Ruffleswinner22 (textures by UFMP and edited by me.)

Feel free to ask me anything about the game and I will answer it honestly.

In some days I may or may not show more information. Who knows.

Expect a similar post soon but covering Update 2 of FNAF 2 CGR.
