AppleFates (Sans AU)

An AU where Nightmare becomes Reaper Sans’ Apprentice and Dream becomes sole guardian of the Tree

[applefates]

Welcome, welcome!! Glad to see you’ve dropped by!

I’m Eris! A 21-year-old enby college student who’s really into Undertale AUs, haha! I’ll be developing this little beauty I’ve got here and using this as a chance to get some writing out for this AU.

Presenting… AppleFates!! This AU seeks to answer the questions: What if Nightmare Sans never ate the golden apple, but instead became Reaper Sans’ apprentice? What would happen to the twins’ relationship? What would his job entail? What would his living situations be? Would he even have his core group of the Bad Sanses? And much more! This is an AU still in development and will grow!

Artwork and fanart is absolutely fine, go wild, but please avoid hateful or offensive content. I’ve been around the fandom enough to know the freaky side, so that’s alright as well! And just please, please no incest or problematic ships. Dream and Nightmare are brothers—they are family—I would like to keep it that way with my AU.

I will get around to all the asks; it will just take some time!

Please be kind to one another. I do not tolerate homophobia, transphobia, sexism, racism, or any hateful/harmful behavior. We all have common sense and I trust we can use it.

(This AU idea was given to me by someone I used to talk to on TikTok by the name of @the_unknown.hatters. It was supposed to be a collab, but he gave it to me due to personal reasons.)

[Oh no! Something fell out of my pocket! Could it be? The Color Sans ref!]

[I had to design him sooner rather than later as he will have a very important role further into the AppleFates lore. And I couldn’t make the Bad Sans poly pride art without him. Some fun little headcannons I came up with as I designed him:]

- The SOUL children all pitched in for something for him to wear as they deemed his usual Sans outfit ‘boring’, that’s why his outfit is…interesting—but he still got a say with the loose-fitting shirt a short.

- The SOUL powers were so strong, they gave him a pair of wings he can use. He’ll joke around and say he drank a Red Bull to get them.

- They have a very wizard-like appearance, and that was very much intentional—he’s got far more control over magic than usual Sanses.

- “A single dad who works 2 jobs, who loves his kids and never stops”. (He treats the SOUL children as his own; it was definitely a lot to process at first, but they work together just fine now.)

HAPPY PRIDE!!!

[Kicking off the month with some Polystars because they deserve so much love omg-]

[I can’t wait to start on the others!! Bad Sans poly must have their moment as well hehe—]

[As well as some other honorable mentions to be seen~]

[I spent this evening charting everyone’s sexualities so I could get their flags right—and it was a BLAST!!]

[applefates]

At this point I should just start giving out dolls of peoples missed loved ones. Cross do you want a doll of your brother? Or everyone except gaster I guess. And while I'm at it does anyone else want one too? Killer? Dust? Horror?

Call me error I guess lol

[Lightning Round #3!! Lots of characters in this one!]

CW: KIller’s arm scratches

[Horror still lives with his brother who is very much still alive, so he doesn’t get a doll—at least not yet >:3]

[Thank you so much for the asks!! Cheers to the next round!! I will probably doing some things for Pride, so be on the lookout for that!!]

[applefates]

[ART COLLAB TIMEE!!]

[Thank you so much @starspeckledbone for doing this collab with me and coming up with this awesome idea!! I had SO much fun!! Your babies are so adorable 😭😭!!]

[For those curious, here was our base! It’s been slightly edited to match character personalities and connections:]

[applefates]

Do you think people pray to null when they want a peaceful death?

[Lightning Round 2!! Serving up 4 asks for your enjoyment! I’m having a BLAST showing all these fun facts and dispersing gifts you all have left for the skeles!]

CW: Killer’s Scratches

[Dust and Horror aren’t the AppleFates variants of themselves, but Killer absolutely is.]

[Null, especially after seeing his brother get hurt by his corrupted counterpart, is very protective of his brother. He doesn’t want to see his only living family member get hurt and get his heart broken. He wants his brother happy.]

[Than you for all the asks!!]

[applefates]

Have any of the twins met/heard of Error. If so how do they feel towards him? (I love you so much)

[Thank you so very much!!]

[I think it’s time for a fun event: A Lightning Round!!]

[I’ve got some character questions I’ve been dying to answer, and I think it’s important to give you all more information of the characters we’re following in the story! This will probably be the first entry in a couple of posts, so stay tuned! Any questions answered in the lightning round are outside of the main story, but still cannon! If there are any burning questions you have about anyone who has a reference sheet, by all means and ask away!]

[Now, on with the asks!]

[Thank you so very much for the asks! This blog wouldn’t be what it is without you all!]

[applefates]

*FLUFFY BLANKET FOR DREAM and a stuffed taco plushie.*

* You give Sentinel a brown, fuzzy blanket. It seems to be made of some sort of animal fur from the lands.

* You give Sentinel a handmade taco plush. He now possesses two stuffie friends.

* You give him a side hug and listen to him cry. You aren’t able to stay forever, but he appreciates your presence, however fleeting.

[I had a lot of fun with this one! And hopefully I drew your character right. I did the best I could with what I could find!]

[Thank you for the asks!!]

[applefates]

Ahhhh Null and Cross, they finally "met"!!

I wonder what Reaper actually wants tho, what does he want with Null 🤔

[I am back!! Null is feeling multiple disturbances in the force—and it is beginning to overwhelm him. He has to do something about it…what he’ll do? One can only wonder… W finally get to see the emotions of stress and irritation show up in AppleFates!! I love the banter between Reaper and Geno—it’s such a different dynamic that’s been established so far!!]

[Thank you so much for the ask!]

[applefates]

[Day 4 of playing catch up!! Finishing off with a birthday piece for Error—and this time, no angst! Ever since I started researching him, I thought it was so interesting he made dolls of the other Sanses, despite his whole existence being centered on destroying them and their AUs. It gives him this unspoken connection between him and them that goes beyond enemies. It speaks to something deeper, at least to me and my AU—to a want to connect with them. Why create dolls if your whole job is to destroy those they’re made after? The dichotomy is fascinating!]

[For those curious, he’s sewing a doll of one of my OCs, Celi, since his birthday is coming up!]

[applefates]

[Day 3 of playing catchup! I’m on a slightly angsty roll which I’m not upset about. I wanted to touch on Ink’s lack of a soul, and his want to ignore that fact, especially in AppleFates. Part of the reason I’ve given him the heart on his outfit, and why it’s green, is him trying to pass as a normal monster, with traits that exist in Undertale, but the fact that it’s not the right color for the Kindness soul trait, not a normal color for a monster soul, and that the icon is 2-D and stagnant gives him away when anyone who knows anything about the life force looks at him. His vials add to that. He’s having to manufacture his emotions. He’s so disconnected yet wants to be fully immersed in these worlds because it’s all he has. Ink is such a fascinating character, and I love to think of his intricacies!]

Edit: Misspell corrected

CW: Killer’s Arm Scratches

[A very late happy birthday to Killer Sans! Better late than never, I suppose. I thought it’d be nice to have a bit of bittersweetness—Killer has his cats, Buttons and String Theory, but he’s…not doing too well… It’s so nice seeing Rahafwabas and Superyoumna come back and build on their characters, it so inspiring—so cheers to Something New!!]

[applefates]

[I’m alive, I swear 🙏🏻 I’ve been busy, and trying not to burn myself out in the process. I’ve been taking time to make other things! But, here is one of many pieces for the many missed special days: Mother’s Day, featuring Nim, Sentinel and Null! I’m still working on her outfit, but I’m enjoying playing with her outfits! Her tree/tendril-shaped hair is everything to me. Knowing Null and Sentinel carry pieces of their mother is so special to me, and I think I illustrated it rather well!]

[And worry not, I will still be answering asks, I’m just pacing myself so I don’t burn myself out 🫡]

[applefates]

[Hi friends! Apologies for the lack of posts these last couple days, I’ve been a bit busy with work and family things. I hope to have something for Mother’s Day! Cheers!]

[applefates]

[No post tonight, unfortunately. It’s been a bit of a long day, and I don’t want to force any art that won’t look good. Will get back to it tomorrow!]

[applefates]

What are your, I want to say boy's preferred weapons... Asking for a friend

[Well, well, here’s the answer for your friend…]

Despite the fact that with enough powerful emotion, Null can summon tendrils, he much prefers the scythe he’s received from being a reaper. In his words, “it’s balanced and fair, and always there when I need it”. Despite it being more curved than a normal scythe, it is shaped that way to reflect his association with the moon. He also has him and his brother’s insignia carved onto the wood of the weapon, so Sentinel is never far. This was the first weapon of AppleFates I’ve ever designed, and I am still very proud of how it turned out!

Despite the fact that he has a bow like his original counterpart, Sentinel much prefers his morning star as a weapon. Aside from the aforementioned Counterparts comics, he hasn’t really had a reason to use such a tool but it’s requires a certain a level of skill to wield he has grown to favor. “The chain can lengthen and retract, and it is exciting to toss around in fun patterns”, he’d say. This is the final design for his morning star, and much like his brother, Sentinel has his and Null’s insignia in the wood of his weapon.

Both weapons have a sharp little point at the end of the weapon, one in gold, one in silver for their respective twin.

[Thank you for the ask! I thought it would be nice to have a shorter but nonetheless thoughtful ask for tonight as I work on the Afterdeath one—which I realize might be longer than I originally anticipated.]

[applefates]

Another teaser for the next ask! Null looks…so done. I can’t blame him—he’s got enough on his plate already. Trying to help Horror, collect the souls to break the Barrier, and now trying to help Cross, he doesn’t really have enough time for banter between these two…‘friends’.
