W.D. Gaster, my little theory *SPOILERS*

[Gnot a Gnelf]

So W.D. Gaster or Wing Ding Aster is a well known character to those who dig into the files or lore of undertale VERY deep. He appears to be one heck of an important character linking him to sans special power, and many other things.
So I went digging and made my own theory about Gaster, what if alphys didn't create the amalgams at all, what if it was Gaster, and she was the filler to his hole in time and space.

So for those who don't know gaster, he was the royal scientist before Alphys and disappeared under mysterious circumstances. The best theory is that he was spread across time and space after an accident involving one of his experiments, he ended up being erased from existance, past, present, and future. He can only appear through grey NPCs who appear to be those to have suffered the same fate, or who are his underlings of sorts. His overall existance is one big mystery but through file digging much has been discovered.

One such thing is in the true lab, the lack of log 17... or so we think. Through file digging one can find this little tidbit of info
"ENTRY NUMBER SEVENTEEN

DARK DARKER YET DARKER
THE DARKNESS KEEPS GROWING
THE SHADOWS CUTTING DEEPER
PHOTON READINGS NEGATIVE
THIS NEXT EXPERIMENT
SEEMS
VERY
VERY
INTERESTING

WHAT DO YOU TWO THINK?"

So I reccomend reading that forum of collaberated gaster info so far to understand the rest of this.

My theory: W.D. Gaster somehow created a rip in space time, and fell into his creation, the result was being ripped from space and time, erradicated from everyones memories. Many of the things Gaster did were replaced by Alphys to prevent a hole in reality, only 1 person is known to have memory as he is also out of time and space, Sans. Afterwards, a hole was left of his existance, at least recent things, and Alphys filled it.

So how did i get to this theory? Well let me explain, lets start with the whole space time thing.
One of the grey NPCs that looks like the ficus licker talks about how Gaster created the core, and then fell into his creation. Bit of a red flag there, why not say he just fell into the core if that was what was to be assumed? Because its not true. I believe whatever this darkness is was what he "fell" into, his tear in space and time.

So that isn't the stretch here, its the part about Alphys, well let me explain.
The pascifist final boss took place outside of space and time, when it was over everyone forgot about Flowey... but why? It was an artificial Gaster incident. The body Azriel resided in was cast off through space and time to be replaced, hence all memories removed, same as Gaster.
Think about it
everyone remembers a flower and thats all.
Papyrus... good god Papyrus was basically his friend and got all sorts of advice, yet somehow he can't even remember what Flowey did.
Alphys made flowey yet the flower comment didn't even cause an eye to bat from her.

This was all temporary though, as Azriel had been limited by his power, and when the world reset, the body was reformed, since it was only an artifical removal to make space for his body.
That leaves some laws in this whole Gaster affair, which i will name off here.
1: Anything removed from space and time will be removed from everyone's memories
2: Only those who have accessed beyond space and time are excluded from law 1
3: Information on the object or person removed from space and time will be forgotten so long as it will not cause ripples or lapses in information/memories.
4: Anything that cannot be forgotten will be filled in with a replacement object/being.
5: *Theoretical* should an object/being return, any forgotten information will be remembered, but rewritten info will remain rewritten or removed. Any time discrepencies will be changed to represent the overwritten timeline.
6: *Theoretical* The cause of removal from space and time of an object/being will also be erased from information and/or memory

This leads into my other cause for this theory, the logs
True Lab log 17
The logs found in the True lab are very uncharacteristically written if we try to put them on Alphys.
The logs are articulate, logical, quick and stammerless, up until log 18, excluding log 11.
Log 17 was removed from existance because it interferes with law 6 and cannot be overwritten since it mentions the rift.
Log 11 possibly mentioned Floweys creation, as 1 log before it was talking about the experiment, which aparently failed, yet "the flower's gone" in log 18, but why would no mention of success or even progess be mentioned before, all progess, no matter how minute was mentioned up until this point on every other experiment. my only theory is that Gaster was referenced too directly to be overwritten, and thus it was removed and the empty space was overwritten by Alphys.
After log 17, the logs become way more characteristic with Alphys, she didn't answer the phone, she was racked with doubt, ext.
Such inconsistent writing leaves me to believe that Alphys took on Gaster's role in the world as Flowey and the amalgams creators.
it is possible Gaster also had something to do with Flowey's powers since Flowey left AFTER Gaster's dissapearance, and it wouldn't be surprising if he took the chance to escape once the time space shift to Alphys was occuring.

the only hole left would be the core, since even looking at it would bring up a hole, but I think it would be mentally explained away with that the creator was anonymous since it was built far before anything in the energy powered lab would have taken place, thus giving a bigger girth for memory slip ups.
In the end this is just my 2 cents, take it as you will.
Also, Sans laser heads and time machine were built by alphys fun fact

[Gnot a Gnelf]

Note: I think that from now on incidents of leaving space time and things being forgotten could be called Gaster incidents to make it easier

[willy bammy]

I feel like after Gaster disappeared Alphys kinda showed up. It's said in game she was responsible for the melted monsters.

[Prosody]

I think the game points to him being Sans / Papyrus "father," seeing that he is named after a font as well. Gaster fell into the broken time machine / dimensional device in Sans' lab and got split into two aspects of his personality: Sans and Papyrus. The game says that Sans and Papyrus just showed up one day, so it kinda makes sense. But whatever. "Gaster" is obviously scraps of cut content / half-finished ideas that Toby left in order to screw with data miners.

[Charlie]

It kinda sucks that we aren't likely going to get any patches with story content according to Toby, so we probably won't know for sure unless he goes against his word, or his other potential games has to do something with Gaster. But I do like all of these ideas people come up with.

[(Edgy) Asriel Dreemurr]

So this is purely hypothetical....

But, what if Dr. Gaster in hopes of finding an AU where monsters weren't trapped underground or as a means of collecting human souls, built a machine that could allow travel between alternate timelines? And Sans and Papyrus are not actually brothers, but alternate universe versions of Gaster, that he came across in his experiment.

At some point however, Sans and Papyrus got trapped in Gaster's timeline (the one the game takes place in) and Gaster tried to help them get back but ended up getting stuck in limbo, erasing his existence from his timeline.

The shopkeeper in Snowdin mentioned how Sans and Papyrus just appeared one day. Papyrus is too naive to understand any of this so he actually believes Sans is a long lost brother, while Sans makes sure to hide the truth of alternate timelines from the monsters in order to prevent another Gaster incident from happening. All that remains of Gaster are blueprints to experiments he left behind, however Sans made sure to hide all evidence of the timeline jumper in his secret workshop.

What do you guys think?

This would actually make sense, since apparently(haven't tried it myself) you get the key to sans' room/workshop by proving to him that you can manipulate save files. This would work well with @randomperson2013's 1st and 2nd rules, since sans would have to be careful not to reveal things to anyone who hasn't accessed beyond space and time by going in his room/workshop.

[Callum ♡]

Sans may not be the only one that can remember Gaster. This is proven when the riverperson says "beware of the man who speaks in hands." This fits in well with Gaster. If you look into it Wing Ding (WD) is actually a font aswell, and its all made up in symbols. So whatever happened obviously Sans isnt the only one that remembers Gaster, but also the riverperson. So what does that make the riverperson? Well im still looking into it, some theory's believe that it could be Gasters wife. However some theory's disprove of that when they say that Gasters wife thought in the battle between monsters and humans and died there, therefore making Gaster commit suicide. Im not sure how correct i could be with this but i hope i can help with some of your theory's

[Michael Myers' Wife ♡]

Didn't W.D. Gaster disappear after falling into the CORE he created? I don't know, I just saw it somewhere. Honestly curious as to what actually happened to him.

"gaster" is not a font. "W.D." is not a font. do you have to manipulate sans or papyrus' names to get fonts?

"gaster's" sprite also does not look much like a skeleton. it looks a lot more like that one thing from that japanese game about the shut-in.

finally, "data mining" is a form of statistical analysis. it is not poking around in the files of a game. that is "digging through the files of the game".
