CHARA, The Fallen Human
The human that comes from the Absolute. It appears when people call its name. You cannot see it, but you can feel the spirit’s presence with a strange sensation. But do not worry, because it is harmless. Moving on, Chara swap places with W.D. Gaster for few main reasons:
Both of them are somewhat dead.
Both of them are the game’s anomalies.
Both are very mysterious characters.
Both of them are even responsible for certain events.
With that out of the way, allow me to explain what and who Chara is supposed to be and what is their role in both earthsecret and AETHERCREST, respectively.
In earthsecret, Chara was the first human to discover the mysterious world below the depth of the ocean. A world where monsterkind dwelled in peace. They grew up there and trained to become a warrior. They swore to protect monsterkind from any kind of destruction. As more children ended up in their world, Chara took care of them all and raised them to become the Underwater Fighters. They were the leader amongst all seven humans [The 6 Fallen Humans swap places with the Gaster Followers/Goners]. Unfortunately, they all fell upon conjuring the Mist [the Barrier replacement] in hopes to prevent the deadly parasite from spreading further. Nonetheless, their spirits lingered in the Underwater...
In AETHERCREST, Chara chose Frisk (who replaces the Vessel) as a subject to set off on a brand new journey throughout the isles for reason that is not known yet. Unfortunately, this course of action was immediately halted by the strange man himself. Chara reached out to some people from the Shadow Realm through spiritual contact and voice. Afterwards, these people began to go insane and all they yearned for was a peaceful SILENCE.
Now, let’s talk about what is happening in earthsecret now that it is going through a reboot.
earthsecret is less about "humans vs monsters" and more about "stopping the destruction of monsterkind". Humans, for now, are portrayed to be mysterious in terms of their existence until AETHERCREST, albeit there are several hints about it here and there. Regardless, the game’s main focus is to prevent "the end" caused by a deadly parasite that turns each monster into goner.
The Barrier is replaced with the Mist from where you encountered Papyrus at the end of Snowdin. The Mist exists to keep the infected monsters sealed within, however the Mist won't last any longer and they will need to find another way to stop the parasite that has already claimed many lives. So you need something to keep it stable rather than destroy it. But perhaps there is a way to stop the infection and the clear the Mist at the same time? Who knows!
Vessel, or whichever you want to call them/her/him/it, is an amalgamation of two different races; they hold the essence of both monster and human. After all, they were created through the magic of monster and the DNA of human thanks to Chara’s willing participation. It is barely Dr. Gaster's successful project called EASE. Vessel contains an empty, star-shaped soul that he hoped soon to be filled by the Player/Anomaly beyond his world. He even uploaded his consciousness to the empty body, so that when it is finally active, he will be able to communicate with them/her/him/it. The STAR is the key to determine the future of monsterkind. Whether it be peaceful or... not-so peaceful?
The Vessel is seen as a threat to some monsters because they look like they have been infected. The grayscale body gives them that impression, and is therefore considered dangerous. Not to mention, they are connected to Dr. Gaster, who has accidentally caused the whole disaster, even involving the president's daughter. On the other hand, some see them as the answer to the cure, and thus must be taken to President Rudolph immediately.
The Vessel is yours to customize. You are also free to add some characters to your creation. Though depending on how you ACT throughout the game, it will give them personality trait. Their name, body, gender, anything else... shape them to your heart’s content and treat them with care. At the end of the game, the Vessel will become their own person and they will not need your guide anymore as they will finally be able to continue with their life normally.
Fun Trivia: there is a hypothetical online earthsecret game as a bonus where Gaster calls all the vessels around the timeline to join and meet every other vessels in his strange void paradise.

Currently, I cannot answer anything related to earthsecret.
A question for W.D.gaster, what do you think about Dess?
Don't you think it's rude to ask someone who's working?
Who does Muffet swap with in Earthsecret?
* And yet, still no one answered.
Does that mean this universe Undertale equivalent have Dess's hyperdeath form named like, Rouring Knight or some variation?
Technically, she turns into "The Roaring Titan".
How come all the Earthsecret tracks got nuked off of Soundcloud? Do you think you could reupload them somewhere?
They're being privated due to the reboot. The songs are still up on Youtube, though.
What is the Undertale soul kid equipment swapped with? (,,,actually I'll ask about Temmie armor too)
I have some ideas, but I'm keeping that a secret for now.
