Gaster, Sans, and Papyrus Alternate Universe Hypothesis

[(Edgy) Asriel Dreemurr]

People seem to believe that Sans and Papyrus knew about Gaster, and that Sans knows about alternate timelines because of an invention created by Gaster.

But what if Sans and Papyrus are actually not brothers, but in fact are two versions of Gaster from parallel universes that Gaster brought to his own timeline?

Now we know Gaster was originally from the timeline in this game, we see his inventions such as the CORE, and the Determination Extractor Alphys built was based on a blueprint Gaster left behind after his "accident". Also remember that the shopkeeper in Snowdin mentioned that Sans and Papyrus just appeared one day.

So what if the machine in Sans's workshop can travel to parallel universes, and it was this machine that ultimately caused Gaster's accident, and how Sans and Papyrus ended up in this universe?

Sans and Papyrus got trapped in this universe and Gaster tried to help them, but ended up getting stuck in the darkness of limbo. This caused all memories of Gaster to be erased from the timeline, leaving only his inventions and blueprints to various devices behind.

So now Sans and Papyrus just live like everything is normal pretending to be brothers (though because any memory of Gaster was removed from their minds and Papyrus's naivete he actually believe Sans is his brother). Meanwhile Sans hides all evidence of parallel universes as well as the machine itself in his workshop so that no one would use it.

What do you guys think?

TL,DR: Sans, Papyrus, and W.D. Gaster are three versions of the same person from different universes brought into the same timeline due to Gaster's experiments with time travel.

Well it can't be true, since Sans calls Papyrus his brother. He even admits that there are other sans out there in the time stream, which would mean that Gaster is his own.

Sans would play along with it because he wouldn't want anyone to find out about it.

What is the line where sans talks about other versions of himself in different timelines, and where does this line happen in the game?

When you're in his fight, he admits to knowing timestreams, and asks you, the player, to not say anything to the other sans' in the different flows of time during a genocide run.

oh, he's talking about the Sans you meet in your playthroughs, not in alternate universes :P

Well, technically, yes in other universes. We can safely say that timestreams can definitely mean universes.

Like the universe I saved everyone, even Youknowwho, to killing them. Or sparing one but killing everyone else, or anything in between.

These fan theories are too good

hmmm... perhaps I should specify a difference between alternate universes and alternate timelines?

I'm aware of that

I guess I should take the time to explain the difference between alternate universes (AUs) and alternate timelines (ATs) based on my hypothesis here.

In this game you are bound to a single universe, you follow the actions of one version of Frisk, with this universe's version of Chara adding determination to Frisk's own granting the duo the power of SAVING and RESETING. This power opens up the opportunity of allowing Frisk and Chara to experience multiple versions of timelines within the same universe, these are ATs. However, Frisk/Chara's power is limited that they cannot jump into an AU.

An AU is a universe where different scenarios in the past (before the time the game starts and you are given the power to SAVE and RESET) ultimately led to that universe being either slightly or vastly different compared to the one universe you are bound to in the game. Chara/Frisk cannot journey into another AU because their saves can only be bound to the single universe within the game. They can create and observe ATs of this universe, but in order to do so they are bound by the physical law that they must RESET to the point they first gained their combined ability (the golden flower patch at the start of the game) and cannot go back further than that.

Gaster is the only person that was ever able to harness the power necessary for traveling between AUs, and how he did it is a mystery and now forever will be since the machine is broken. Sans and Papyrus are different versions of Gaster from other AUs. Without Gaster's machine now, the skeleton's like Frisk/Chara are bound to the universe seen in this game. As Torashu pointed out Sans mentions other Sans in other timelines, these are the other versions of Sans you would see in multiple playthroughs in the many ATs you can create in this game.
