EX Brothers

The EX Brothers are three side characters that appear in Chapter 1. They can be encountered after opening the secret passage inside the library after getting the side quest from Sal. Each of their names is based on the first letter of their color name and "ex" after it.
== Appearance ==
They do not have a visible physical appearance with the exception of their eyes and Pex's mouth, which is seen when Pex is about to eat the player, with each of them having different color.
== Backstory ==
According to Pex, one day the EX brothers suddenly found themselves trapped in the basement, with no memories of any past events. While Rex loved the basement as his new home and Yex did not care, it was horrifying to Pex, so he started seeking for the answers on how they happened to be there and what is their purpose. Eventually, Pex found and grasped all the answers he needed, but went insane due to the nature of the answers. Since then, he wants to consume anybody other than his brothers. As Rex describes, Pex has eaten "dozens of intruders."
== Coverage ==
While meeting the player, Yex at first feels a little annoyed of having someone else locked in the EXs’ cold and dark basement. Quickly after that, Pex appears and wants to eat the player. Finally, Rex comes and is very annoyed that there is a player with them. Rex forces the player to do a challenge which would definitely kill the player. Yex is terrified of that happening, so he tricks Rex into making the challenge a dance, since some "challenge" videos on the internet involve dancing. Rex gets mad at Yex after the player finishes their moves and lets Pex eat the player.
The player then would proceed to enter Pex' stomach, surprisingly alive. Upon entering further inside, the player would have to go through parkours and various obstacles, before entering the "anatomical hub." As the player enters, four doors are seen, one which is the Head is locked with 3 locks, which appears to be the color purple, and finally, the other three doors are to enter and collect three keys to unlock the head, appearing red, orange red, and magenta: the Heart, the Liver, and the Lungs.
After the player collects all 3 keys, they can unlock all 3 locks on the Head door, and enter inside. Once they have entered, they encounter Pex's eyes breaking something resembling a barrier. Afterward he turns to the player and quickly falls in disbelief and throws a tantrum to get them out of his head. He would then explain how it all happened that changed him which prompts the player to alter his mind, triggering a 400-second minigame where they must connect multiple lines to fix Pex.
If the player succeeded in fixing Pex, he would barf them out and approach the player, surprised with how they were able to fix him. Yex then appears confused looking at Pex in his normal state. Feeling skeptic, he challenges Pex to guess his favorite color which quickly got answered correctly. Yex now realizes Pex is truly back to normal after a long time of insanity though not long enough Rex appears, disappointed seeing Pex barfing the player knowing the fact he ate a lot of "intruders" in the basement. After some explanation, Rex apologizes to the player and now treats them as a guest instead of intruder and receives the key. 
Although alternatively, if the player fails in fixing Pex, the same outcomes occur except for some dialogue during the barfing scene. Once barfed out, Yex will approach the player and will be lightly surprised finding out that the player was alive, before shifting his attention towards Pex as he finds out that Pex isn't being responsive, who would eventually reveal to be deceased in this route, throughout a few dialogues, Yex would plead Pex to wake up finding Pex deceased. The player would then freely be able to move and exit through the elevator, leaving Yex mourning over the loss of Pex upon his brother's corpse, Rex would also be nowhere to be found nearby. Fortunately, the player is still able to obtain the key automatically after the event.

== Trivia ==
*They were confirmed to be cats.
*At least two of them have written the books in the basement.
*During the Gatekeeper event, sane Pex told the player that the Gatekeeper "is on his way" instead of thanking them for repairing his mind. 
**This might mean that the repaired mind of Pex has inherited some or all of the exclusive knowledge from insane Pex though there is a chance of Pex's knowledge inheritance being non-canon since it is exclusive to the event.
***This is also backed by gwig announcing everyone not to take some of the Gatekeeper events seriously.
