References 2026: UTBST!Sans𝛹

I made new reference sheets for UTBST!Sans! 👌 There are 6 in total. As noted on each one, they are incomplete; for more details, you can check my references and additional sheets in my UTBST Gallery on DeviantArt 💛

UTBST SANS - References and Additional sheets by LawliaArt on DeviantArt

Browse lawliaart's UTBST SANS - References and Additional sheets collection on DeviantArt. 28 works of art.

I mainly made them so there would be recent drawings for the different “versions” of him that exist from ages 35 to 47/48. And it will be more convenient if someone wants to create fanart 👍

As a reminder, there are 2 versions of UTBST!Sans: one comes from the "Black Soul Timeline Good Ending" (BST G.E.), and the other from the "Black Soul Timeline Bad Ending" (BST B.E.). They are identified on each sheet in the red box at the bottom right, where the timeline name is specified. The last sheet is a non-canon version of UTBST!Sans B.E.; it shows what he would have looked like if he had not been saved: this is UTBST!Sans.exe, where the alter called Exeller has taken control of Sans’s body.

I wanted to thank you all for the support you’ve given me, I’m truly happy that my Sans OC is so appreciated! Thank you so much 💛 He may just be a fictional character, but he means a lot to me. When I think about it, I’ve gone really far with his lore haha, and it’s not over yet 😉

𝛹

{Certain aspects differ from reality to fit the lore, the act of killing should not be associated with bipolar disorder or DID ⚠}

{For the two drawings featured on the first and second slides, I based them on the cover of chapter 85 of the manga Witch Hat Atelier by Kamome Shirahama.}

LawliaArt/Lawlia Sona - Reference Sheet 2026

It's been ages since I last drew myself, so here's a little reference sheet for my sona 💛 Even though I don't draw myself very often, I think it's always nice to have an up-to-date reference 👍

I also took the opportunity to add all of my Sanses, this time with more canon-accurate proportions (for Sans I'm not sure the term chibi really applies XD). UTBST!Sans is currently my most developed Sans, I'll develop the others more over time 😔✨

UTBST!Sans Psychology Profile 𝛹5: History of tobacco use + Lore

Here’s a fifth psychology sheet for UTBST!Sans𝛹 💛 The fact that he has a history with tobacco is something I had already mentioned in previous sheets, but I thought it would be interesting to make one that focuses specifically on that aspect. It also gave me the opportunity to add some information that I think is worth knowing 👌

For this sheet, I also went over the lore as a whole again to bring back the context and make it easier to understand, but of course I didn’t go into every detail again so I wouldn’t stray too far from the main topic. So, as mentioned on the sheet, for more information you’ll need to check my previous sheets/references.

I think I’ll make a few more sheets like this for him in the future. Even though I’ve already covered the main points overall, I think there can always still be more details of this kind to add 🤔

ART FIGHT 2026 – Art n°6, Revenge: Cart (Sona) c_art_artwork

Here's my last Art Fight drawing! This is Cart, a sona ✨ I really like his design and I love his Sans vibe he has the same smile I love it 👌 He was really fun to draw! For the background, I just did whatever came to mind and added Endogeny (the dog amalgamate). I think what I made is still pretty simple, but it's okay 😔👍

I drew TT!Sans (older) from TimeTale, an AU by AllesiaTheHedge 💛 Here he's wearing the outfit he'll have at the end of the comic, I thought an autumn-themed background would suit him really well 🍂

I love this AU, it's one of my all-time favorites ✨ The story is so well written, and every page of the comic is absolutely stunning, I love this Sans so so much 🙏

And here is version 2 that I made for this trend! 💛 For this one, I based it on a reel by naradrawsstuff (redraw). I really like the pose that was used and the idea of the mirror, and I quickly imagined in the place UTBST!Sans G.E. Epilogue with UTBST!Sans.exe (UTBST!Sans T.B.E. aka Exeller).

As a reminder regarding the lore, this version of UTBST!Sans B.E. (True Bad Ending) is not canon; it's what he would look like 11 years later during the Epilogue if he had not been saved, with Exeller being in complete control of the body here. In this non-canon version, UTBST!Sans G.E. will be brought to confront him, so I'm counting on his friends to save him because he is really no longer capable of fighting 😔🙏

For more information, you can check out my UTBST Gallery!

UTBST Animatic: Your Next Opponent is You – Version 1 [Resets 159->160]

View this post on Instagram

For this trend, I chose to make 2 versions, the second one will arrive this week! 💛

Here, I depicted Sans at Reset 159, right after he defeated Chara and recovered her soul, just before absorbing it, and then at Reset 160.

As a reminder in summary, after absorbing Chara's soul, this will cause him to have an excess of Determination. On a psychological level, he will develop Bipolar I Disorder with a particularly dangerous manic phase (I would like to clarify here that this is an extreme case for the lore and therefore is not representative of reality). So, at Reset 160, UTBST!Sans is the one who has become the problem (and it is no longer Chara), because Sans will no longer be able to have total control over himself and his mood will become very unstable. (And in addition to this disorder, it should be noted that he already had smiling depression and Binge Eating Disorder.) On a physical level, he experiences much more intense fatigue with severe insomnia, he sweats a lot, drools, can sometimes vomit, and has become hypersensitive to pain... (I wasn’t very nice to him I know 😅😞)

For more information, you can check out my UTBST Gallery! (Link in bio) 👌

ART FIGHT 2026 – Art n°4, Revenge: A Happy Ending ♡ @strawberrygirlsimp

Art Fight

An art gifting game

My friend Berry attacked me with a drawing of Ekko and Pantoufle, so I felt like doing the same, but I added Hated!Sans G.E. and UTBST!Sans G.E. 💛 The background was inspired by a drawing she made

Drawing ships isn't really my thing, but I did my best ✨️ They're so cute together, I love them 🫶

❗ As a reminder regarding the lore: UTBST!Sans G.E. and Hated!Sans G.E. are a couple (not in the B.E., where they're just friends!!). They first met in the Omega Timeline when UTBST!Sans G.E. accompanied UTBST!Frisk B.E. to help with the search for the Sans from her timeline. After that, Scars G.E. and UTBST!Sans G.E. kept meeting regularly, eventually became partners, and moved in together in the Black Soul Timeline G.E. after UTBST!Sans B.E. was rescued. As for Ekko, he's a 9-year-old skeleton child who was already with Scars G.E. in the Omega Timeline. Later, UTBST!Sans G.E. and Scars G.E. adopted him together. (It's all written in my sheets, but I prefer to mention it every time anyway 👌)

ART FIGHT 2026 – Art n°3, Revenge: Loki!Sans (21yo) darkness_artist_x

I felt like drawing Loki!Sans in his younger 21-year-old version, and I made a Snowdin background. I don't know the AU, so I hope it's okay 🤞 I really loved drawing this OC, and both of his designs are amazing! 💛

ART FIGHT 2026 – Art n°2, Attack: (Pre)HDCC!Sans, HDCC!Papyrus and Malva @annit_art

Second drawing for Art Fight 💛 I really loved making this attack ✨

I was thinking of doing something darker, but in the end I think it works well like this too. And for (Pre)HDCC!Sans, at that point he’s not supposed to be chubby yet, but I have to admit that, for me, it felt a little weird to draw him any other way, so I left him like this 👉👈

PS: There normally isn't any snow in this universe, oops I didn't know 😞 So I’ll use the excuse that Kyurem passed by 😂❄)

UTBST Animatic: Twins at the Carousel [UTBST!Sans B.E. & UTBST!Sans G.E.]

View this post on Instagram

I love this trend, I absolutely had to do it! 🙏

Here, I represented my two UTBST!Sans B.E. (Bad Ending) and G.E. (Good Ending) 💛, after the events of Reset 160 for the two Black Soul Timelines (BST), where, as a reminder, there was a different outcome for each: UTBST!Sans from the BST G.E. was saved, while UTBST!Sans from the BST B.E. was not and left the timeline (but he will be saved 11 months later!).

Officially, they are not supposed to meet during this period, or perhaps only catch sight of each other, but they will not have any contact. UTBST!Sans G.E. will help so that he can be found and saved, but that's all, he will never intervene directly. But when UTBST!Sans B.E. is finally saved, the two of them will meet and become friends ✨

And regarding Chara during this period, for UTBST!Sans B.E., she is still present within his soul (red appearance), whereas for UTBST!Sans G.E., Chara has been saved (blue appearance), and their two souls have been separated 👌

Asthar!Sans Fanart

This is a gift for my friend Skyy ♡ It was his birthday on June 28th, so I'm a bit late, but better late than never XD

I took inspiration from one of his drawings for the background, where he drew Asthar to introduce his theme music, which I absolutely love, by the way ✨

I'm not entirely satisfied with it, but I still really like how it turned out! 💛 I'll make another drawing next month, I’d really love to draw him again with Black 👌

I hope you like it, Skyy ♡

And please go support him! 🙏 His work is incredibly impressive, and I can't wait to see all of his upcoming projects! 🙂‍↕️✨

ARTFIGHT CARD 2026 - TEAM MYSTERY

This is my third time participating in Art Fight, and I've chosen Team Mystery 💛

I’ll attack artists who have characters I find interesting 👌

For revenge, I’ll be prioritizing people on the opposing teams I’ve never drawn for (or only a few times)!

I’ll try to reply to as many people as possible, but I can’t promise anything 😔

REFERENCE 2026: UNDERWIFI!SANS

I've updated UnderWifi!Sans' reference sheet! 💛

UnderWifi is my second main AU (the first one is obviously UTBST, and the others are TheLastTale and the Shadow Timeline). I absolutely love this Sans OC, he's my favorite after UTBST!Sans 🙏 yet I haven't drawn him much lately, so I had to do something about that XD

For the ref I reused what I made last year, expanded it, and fixed the inconsistencies I noticed. I just hope there aren't any more left 😔 And regarding the lore, I haven't developed it enough yet to share much more, but I already have a very clear idea of how the story begins and ends 👌

So, is this Sans a villain? Yes, but he's still redeemable 🙂‍↕️💛 By the end of the game, when the monsters return to reality, I imagine his disorder has stabilized, with less intense symptoms that are much less disruptive for him. He also won't hate humans nearly as much as he used to! And that's actually the reason why he started killing humans, to collect their souls and free the monsters. Since humans were the ones who killed his father, he wanted to get revenge, and... well, that's how it all started... 😔

Sometimes I feel like I'm giving a terrible image of certain mental disorders through him (schizophrenia) and UTBST!Sans (bipolar disorder/DID) 😭 But as I mentioned in their refs, their disorders should not be associated with killing people. They're meant to be... extreme cases 😅

That's pretty much everything I wanted to say! If you have any questions, feel free to ask, and once again, thank you so much to everyone who supports me 💛

(And yes, this Sans is chubby too, but no one will complain, right? 😔)

Pantoufle the Amalgamate Cat (UTBST!Sans’s Cat): Updated Reference + Art

I've updated the reference sheet for Pantoufle, UTBST!Sans's cat 🐈 I reused the information from the old reference, rephrased it with additional clarifications, and added some pretty nice extra details 🙂‍↕️✨

As for the summary included in this reference, I only mention the essential information you need to know about Pantoufle's lore. So, for more details regarding the events that take place in UTBST, you'll need to check out my references and additional sheets available in my UTBST Gallery on DeviantArt (link in bio) 👌

As for the context of the first drawing, it depicts the first meeting between Sans and Pantoufle, after Alphys found him and brought him back to her laboratory 💛
