I have poured a lot of effort into this so I really hope it does well, but either way sorry for not being more active this year, a lot of stuff has come up and it became really hard for me to put effort into doing anything related to the channel. Despite that, thank you for continuing to support my content! Next year, I'll do my best to make sure that it is the best one yet!

    Corrections: Storyshift - 05:18 - Technically not a correction, but Storyshift has a reboot! (which I had no idea about lol) - From what I've heard its really well written and you can find it here: - Tumblr: ut-storyshift.tumblr.com/tagged/official-reboot/ch… - Archive of our Own: archiveofourown.org/works/19019659/chapters/451690… Dusttale 08:08 - I was very much spreading a lot of misinformation (probably also didn't help that I was making a joke with Murder and Killer being similar and so used the same script but you live and learn if), but just to clarify I was referring to FANON Dust as, imo he's more well known - Just to make things completely clear: - Frisk 'convincing ' him was meant to be a metaphor about how Frisk drove him insane - CANON: - Not a merciless killer, very much doesn't forgive himself for killing his friends - Not a servant to Nightmare (in fanon their relationship differs from AU to AU) Insanity Sans 09:50 - It is getting/has gotten a reboot (?) and is now owned by: youtube.com/@UTF06 - No idea where to find lore or updates? try their discord server?? discord.com/invite/FmtereMeRM Dreamtale - 10:58 (ty xXtha) - Dream was not friends with the villagers, his only friends were Nightmare and Neil. He was friendly with them however they took advantage of him - The man Nim killed is only a part of corrupted Nightmare, not the spirit itself - No one was allowed to 'try' the golden apples and no one came to try the apples after the man Nim kills. A human who ate more than one apple would die and the whole point of the guardians is to prevent people from trying the apples - There was no single 'corrupted' apple. The spirit lived in the tree and was the one that convinced Nightmare to bite the apple - Dream wasn't trying to save his brother at that point, he was trying to save the apple and those who were left FROM his no longer brother - Nim does not die, remnants of her are still seen in corrupted Nightmare - Nightmare's 'scheme' is to get Dream out of stone and kill him which is pretty important Inksans - 13:12 - The portal at the end of Ink's comic is a portal to the multiverse and while he does take on role as the au protector, he thinks the emotions he got were by accident and his motives are now partially selfish to keep that going (rather than some true purpose) Epictale - 18:50 - (I briefly mentioned it but) It also got a reboot! Read here yugogeer012.tumblr.com/post/190998137050/epictale-… Fusions - 28:34 - Dustswap and Dusttrust are different. Dustswap is where Underswap Papyrus commits the genocide whereas Dusttrust is where Underswap Papyrus starts the genocide, Underswap Sans kills him, he learns about the genocide routes and then proceeds to continue the genocide Papyrus started

    This whole video baaasically shows my problem with how people view AU’s. This video is titled “The entire AU Undertale Multiverse explained” but it FEELS more like “Every version of Sans explained.”
  • @reinbew794
    I love how it became a "Who can make the edgiest and most powerful Sans" competition at a point.
  • If you have the mental brain power to understand both alphatale AND godverse your probably the smartest person in the universe tbh.
  • @DragonSkies0211
    When I was younger and first got into the fandom, I mostly watched animations and comic dubs with the audio off. The supreme lord of the fandom back in the day has to be the Sans Multiverse Christmas comic, if you were active in the fandom you had to know what that was.

    Correction in Storyshift: Storyshift has a rebooted version, due to what happened with Voltra in 2016, with harrasment and missunderstooding her AU, making Voltra having suicidal thoughts. The AU had a hiatus and now, it's back. With a reboot. The new reboot of storyshift is making a new storyshift, completely originally written. Chara is a jaded and cynical Human, with a deep hatred towards Humanity. Being hidden by Toriel and Asriel. Due to the Solar Warriors. Monsters that aren't on sans rules. Planning to kill the Humans, Unlike in sans rules. That he said that humans are friendly. Chara also doesn't have magic involving towards Knifes. But Plants Magics. Anything related to plants. Such as friendly pellets, vines, flowers, leafs. Etc! The personalities on storyshift are not swapped or shifted. They have their original personalities from UNDERTALE. If you want to read. Check on storyshift's reboot tumblr. Corrections in UT: Insanity. Aka: Insanity Sans: Insanity has a new story and writing, due to the change of ownership. The new Ownership is UTF. and the story is being totally remade. Insanity's blood is not actual blood, but a modified Determination. Due to what happened on the experiments on a Bravery SOUL's DT. Insanity has a unlimited amount of DT, but he can be easily defeated. Due to the low amount of HP and DEF. Insanity likes to use punches and bones, rarely using Blasters. Only in a dangerous battle. Correction on EpicTale: Epictale got a new reboot. You can read it in yugogeer's tumblr.
  • @AshtinoPatino
    Woah someone actually tried to understand godverse
  • @TheMostDisabled
    The more I learned about Underswap it isnt exactly swapping the characters entirely. It's basically nerfing their main personality traits then adding the character that they're swapping with. Like how US Sans still like puns but also enjoys cooking and traps.
  • @dragonkaiju78
    Just a small correction, 8:09 dusttale's story is that sans suddenly remembers all the geno routes, and he does his own to prevent any more geno routes from happening.
  • @paradoxicalavel
    I think, and I’m sure many people do, that you really did a good job piecing it all together and explaining each thing in detail in a way that even people who are new to this understand. And yes, I agree. The godverse makes no sense at all-
  • @user-es2bb3ux8t
    I really Love Horrortale It shows what happens after The Tradegy (Mostly) And Creativity About Undertale's Neutral Endings
  • @paperprince2953
    Corrections: - Whether it was a joke or not, I have to clarify. The golden tooth was merely the creator's head canon for the original Sans which. If you see any of Fella's drawings for other AUs like Underswap, you'd see Sans with a silver tooth and Papyrus with a golden one. - Oh my gosh, enough of the Undertale AU Wiki's misconceptions. Kindred Spirits is not even the first AU, not even close. The first AU was actually created at the same day but unlike Kindred Spirits, we have an actual confirmed time/hour it was made. The AU is called Overtale. - Kindred Spirits is the third AU A bit of a shame you never mentioned Storyspin (personal favorite), Underworld or even Jumbletale,
  • @ImHungryAsHell
    HOW IS THE FANDOM STILL ALIVE AT THIS POINT!?!? MY GAWSH how many screenshots and/or videos did it take to make this
  • I have a feeling that If an Undertale fan was some kind of rich person, then they’d go to the actual MT. Ebott irl and then completely recreate the Undertale map under the mountain or something. How funny/cool would that be?
  • @KRDsonic
    As someone who is pretty new to the whole Undertale AU thing, this video was very interesting. I read Endertale and Aftertale a couple days ago. I had absolutely no idea where to start next considering how much there is. I had no interest in Horrortale when I saw small bits and pieces before and didn't think it would be my thing. I took your recommendation though and read it. I definitely agree, it's pretty good! Edit: THANK YOU for the google doc too! It makes it so much easier to try to find everything.
  • @greenhydra10
    Wow, I don't think anyone's really tried to make a comprehensive explanation of the "major" AUs before. Even Godverse and Alphatale are in here too. Maybe I'll learn a few new tidbits. Nice to see Underplayer, Bad Time Trio, and Inverted Fate in here. One correction for Dusttale, Sans does his own geno route of his own accord, specifically to stop the human. And one correction for Aftertale, Chara doesn't take control until multiple geno runs after Geno is "created".
  • @izzylikestuff_
