    I have a small theory notice how Kris has the same outfit as Chara and never shows her/his eyes also in the beginning it asks you to choose a vessel like your a ghost like Chara also it’s like Chara never controlled her but in the end it’s like Kris changed she had red eyes and a knife also Kris ripped their soul out so that probably means Kris is Chara

    I'm not even gonna watch this because its so clickbait and the fact that it isn't your story its all laid out in the passive route. Flowey(azriel) even said I thought you where her. Its not a theory its clickbait. Stop telling us things we know!

    I dunno why but I can't wait for like at least two of these videos to be debunked/confirmed whenever Deltarune is released.

  • Kit Z
    Kit Z 4 days ago

    wait. But what about Papyrus and Mettaton. Their personalities are not related to the war. Well maybe Metta cuz Alphys built his body which made him more confident. But papyrus? What's up with him? Wouldn't he be elated at the prospect of making new friends or someone knocking on the door? The only explanation i have atm is that sans when taking back the house/grillby's also took Papyrus and explained to him everything or at least told him not to open the door on that day because of the player. Either that or he had a sick day idk.
    Also, also, where is Grillby?! You see his niece. But like where's the actual flaming guy. I kinda wanna say something's up with Grillbz. Mainly because had Sans rebuilt the bar and house in Deltarune from Undertale that wouldn't explain why the need to write then cross out the name Grillby's. So if we're going with Sans physically plucked the place from the ground and shoved it through a portal where be Grillbz. Hell if catty and bratty are there then there should be Grillbz. Maybe he just doesn't exist but I doubt it.
    Also,also,also why would sans need to bring the house? That raises multiple questions. Considering if he did that he would've had at least a little time to prepare so he would've known what was happening but then again why move? Is it because he knew US the player were gonna be there or is he bound to Toby Fox as he moved over to Delta that meant Sans also needed to move to the new 'universe'. Or was it something else?
    IDK THAT'S JUST A MILD VAGUE THEORY!!!!!!!! A MILD VAGUE G A M E THEORY!!!!!!

    I always get chills when I hear the robotic “delta” that sounds like gas-
    wait.
    The robotic “delta” at the end of the game must be Gaster!!
    That makes so much sense!
    This is a future that Gaster is creating with the player.
    And at the end of the game, Gaster ends the story, by saying the name, “delta”.

    If you ask me ( your not ) then Deltarune is the past of undertale think about it ( you don't have to ) undying has both of her eyes ( mabey she lost them when she was fighting one human soul, and Torio she was a teacher when the monsters were on the surface that tells how she knows how to read or loves to read and teach. And the only way alphys and undyne would have a connection is when alphys ( when the were put in the under ground ) was explaining to undying about the humans and about determination. And toriel and asgore as you can see in undertale they have been divorced they have grown old so that must mean that they had a divorce wayyyy long ago. And finally krisk and Azrael ( I BET I SPELLED THAT WRONG SORRY IF I DID XD ) I think that krisk is chara.. I mean at the end THEY has the knife, red eye, and while you play the game have you stop to think ( well of course you didn't you were too focused on digging the game ) they have the same hair and the same yellow and green striped shirt..

  • The Judge
    The Judge 13 days ago

    My personal Theory:
    Well if u go with the genocide ending that means that deltarune could have come from Caras literally saying how shes on to the next world. Not only that the words "dont forget" is present in both games. Plus Sans being a super aware being notice this. I think it is a sequel in the form of a new universe. Think about it Cara finally gaining control takes control of the entire universe. Now what's Intresting about this is if u play undertale and choose Genocide it does effect all timelines. 🤔 therefore u could argue that is the one canon ending that effects all other worlds like a ripple. What if deltarune is what Cara created. Think Sans says theres a disturbance what if this disturbance is deltarune. Not only that what if this is Cara whipping out the idea of the war and instead creating her own story. One were none can really change. Just try the player cant change anything.

    • The Judge

      U see I think it is That Cara is speaking to Kris but not to blindly take over for a jump scare jus like u said. Instead I think Cara simply doesn't want any interference in her new world
