    My theory:
    This two names uses the same Letters unless there is "f"in frisk but not in kris
    Why f?Maybe it stands for something and it could be
    *F* riends
    *F* uture
    *F* amiliar
    So in my theory deltarune is just a another timeline in another Au, thats Why it is *familiar* to undertale and there is the same people which were our *friends* in undertale. But they dont have the same past so their *future* is different! Also I Said there is no f in kris but there is in frisk. Because frisk doesnt understands that we are controlling them they think its their choices and they think they are free. And altough we controll kris they are aware of us. And they separate our souls in the end. Remember we created a soul at the beginning. We actually tried to replace it with kris 's soul and controll them just like we did to frisk. But we couldnt. We put our soul into kris' s body but we couldnt get out their, thats Why we cant change the story we only could change little details and in the and kris rips our soul and puts it in a Cage to save themselfs. Also another thing name is
    delta Run
    İsnt it familiar to
    Genocide run
    Pacifist run
    Neutral run
    So normally it was going to be a part of undertale but like I Said it happens in another timeline another universe and another story. Yes it is connected to undertale kris is connected to frisk because in both we are replacing a person soul with ours. But deltarun isnt undertale s past or future its another universe.I know you think the dog Said its not connected. Yes its not for the story. İts just another universe

    Alright hear me out! The turtle guy is dead in deltarune but alive in undertale. In undertale when you talk to him he'll say hes a shopkeeper and that's why he's lived so long (or something like that) but in deltarune he has no reason to be a shopkeeper! Thats probably why hes dead.

    This is just an imagination from a simple teen: if we can still move the soul when frisk throws us out, could that mean that gaster or 'the mystery voice' at the start, give us the vessel we created so we can fight Kris? Or something else, sans could give us back our Frisk body (as he knows about all our resets) so we can fix this time line with his help. SOMETHING ELSE THAT I JUST THOUGHT! Sans knows about gaster being in this time line and will bring our cage to the secret locked doors, the doors leading to a DIFRENT laboratory just like the one sans had in undertale so he can give us a vessel

    10:20 the difference between Toriel from undertale and deltarune, is that she doesn't use fire magic to cook just like Toriel from undertale.

    Also one small but actually big difference is that Sans remarks about having an younger brother in Deltarune, while Papyrus is Sans's older brother in Undertale. I think that the difference between the worlds of these games is not just war, but possibly something more.

    5:20 Well at one point humans were in peace with the monsters then they thought Asgore killed Chara so it was probably a prequel.

    With the save file thing, when it says “by second nature” it’s because toby had made deltarune after undertale, most people who have played undertale will also play deltarune. That’s why people call it the second game.

    Deltarune is probably gonna appear in Underverse season 3.

  • Green Blupee

    So the soul is us and Gaster's trying to contact us, right? He had us create a vessel for ourselves, likely to navigate the world in since he tried to get us here. He makes us create a vessel and shape its mind as our own. But then when it's all done, it's discarded by someone else (I'm assuming it's someone else because the text style changes; only the beginning words of sentences are capitalized rather than all the letters, the font is different and also not all blurry at the edges, it also seems like the other person's text goes faster but that could likely just be my eyes tricking me). They say that nobody can choose who they are. But Gaster essentially told us to make it like ourselves, right? We can't choose who we are in our own world, true. But assuming we actually do make the vessel in our image -- assuming we don't lie, make someone else, pick things at random, etc. -- we're not "choosing who we are". We're still us. We're just kinda being transported into that world and we needed a way to do so to connect with Gaster that was still recognizable as us. I feel like that avatar is gonna come back in later chapters. We'll likely need it now that we can't control Kris anymore, so we still need a way to play the game. Unless Toby decides to make us possess some other human child, idk 😅
    And perhaps Sans recognizes our soul and thinks it's Frisk? Or maybe he knew we were the soul in Undertale in the first place, though I'd probably have to replay the game in order to figure out if that's true at all.

    i know this video is a little more than a year old but I thought I'd comment anyway since I've been replaying it lately, even if nobody's gonna read this. Still wanted to get my thoughts out.
