Undertale Lore - Tumblr Posts

Apparently this is the gaster newsletter but take this witha grain of salt it could be fake but i dont think it is!! heres a transcription btw

Transcription:

(its a strange letter. its more or less completely illegible.)

(but, if you squint your eyes and squint your heart.. For some reason you think you can understand it)

In all caps the message reads:

Well. Happy new year! Or, was it the old year? Well, in any case, how is Delta Rune? As you are waiting patiently, time is going around. theres even a rumour of a "valentines day". How absurd. Every day is a day of love. If you believe it so. Do you believe it so? ... so. the purpose of this message. I want to help! Yes, there was someone I wanted to help. I seem to have forgotten who. Yes, its quite ironic but I seem to have forgotten. was it myself? no... well.. perhaps. regardless, when i see them, im certain i will know is straight awaay. I never forget someone i dont remember. Will you help me? ... you are very odd. responding out loud to a letter. but, you seem reliable. I will be counting on you. now, put on your coat and wash your facew! or, put on your face andx wash your coat. Not necessarily in that order. Or, in any order at all. Good by! ( there was a sound like something walking away and. the letter was gone.)

The Red Soul: An Undertale Theory

In the Undertale universe, there can only be one red soul, and it is passed onto a different human after its last vessel dies. That is the theory, and let me explain why I think this is the case.

When you are playing Undertale for the first time, you're led to believe (for the most part) that you are naming the human that you play as (Frisk). The name you pick is shown in the stats menu and it's shown right next to your HP and LV during battle. This wouldn't make sense if Chara and Frisk had two separate souls. This theory explains that: last time, the soul belonged to Chara, and now Frisk has Chara's soul.

Furthermore, I think it also explains why Chara slowly takes control over the course of the Genocide Route. Flowey, despite being a fucking liar, explains this as soon as you meet him: your soul starts off weak, but grows stronger with LV, and guess what you gain more and more of as you progress through the genocide route. That's right. LV. LOVE. If it were Chara's soul, that would perfectly explain why they take over - because when Chara's soul grows stronger, Chara also grows stronger.

Lastly, this explains why Flowey/Asriel believe that Frisk is Chara, despite them looking clearly different. Asriel would've most likely seen Chara's soul considering he absorbed it as part of Chara's plan. Since Asriel and Flowey both see your soul at the start and end of the game respectively, it would make sense for them to believe you are Chara if you were controlling Chara's soul.

So that's the theory: the red soul was once Chara's, and now it belongs to you.

Because Frisk does not remember a true reset. On normal resets, Frisk turns around and shakes Sans's hand before they are told to. The only reason this interaction would not occur on a true reset is if Frisk didn't remember it.

If you go back to the game after a true pacifist run, Flowey says "Let everyone be happy. Let Frisk be happy." A true reset goes against what Frisk wants. Normal resets are performed by Frisk. True resets are performed by YOU.

(Note that the question is HOW aware, not IS he aware)

EDIT: I think my question may have been somewhat misinterpreted based on the responses.

The "all his knowledge is just based off observation" choice implies that he has LESS deja-vu than other Undertale characters. If you think that Sans has no more and no less deja-vu than monsters like Toriel (Remembering your pie choice) and Undyne (Getting a feeling you might have been friends before), pick the second option. Choose the first option ONLY if you think he has a weaker/non-existent sense of deja-vu compared to them.
