I didn't make an armored Dalv design for Sw!Fallenswap yet, so I made one, also plus a mini comic ft: swapped version of Ceroba, Starlo, and Clover, that was originally just going to be a bunch of reference doodles but i decided to just make it into a comic thing. I'll try to get a zenith Martlet version of Dalv design done eventually.
(Dalv swaps with Martlet, Ceroba and Starlo swap with each other, and though it's not a complete role Swap Clover and the kindness soul do swap some characteristics with Swap Clover having certain traits more likely to associated with a kindness soul those being having a more of a ditzy and whimsy demeanor and easy-going temperament)
Just some random Sw!Fallenswap Undertale AU Drawings
Yes, I know Dalv's bow isn't completely animated, I got bored and wasn't feeling up to completing it, also one of these is unfinished and decided to abandon the drawing so I just changed the blue layer to black so that's why that one looks very unpolished, missing her face tattoo and why Red Bandana isn't in proper perspective
Just wanted to Draw SW!Fallenswap Toriel (she has been ever so slightly redesigned)
Information on her below the cut: (some info might be outdated)
Toriel information:
“Want to know something ironic, child? That my behavior got my own two adoptive children killed. And now what I do in response is to kill the children of others… It’s funny, is it not? But, I highly doubt this concerns you… Anyway… What is your name, Child? … Chara…? Well… I’ll never forget you, Chara. May [God] forgive me”

Personality:
Toriel is a relatively intellectually curious individual and overall kind individual, however she is not without her flaws, Toriel is prone to anger and can be short-tempered to the point of violence, she is also incredibly paranoid believing most are out to get her due to her status as monarch, causing her to act in controlling ways and executing or silencing anyone she finds as a threat to her, while this isn’t always unfounded, Toriel did wind-up with a hefty body count of an estimated 200 million +6 humans over her 1000 year reign.
Quick History:
Early Life:
Toriel was born around 997 to Jazzimine and Alexander Dreemurr, not much is known about her early life before her teen years, but here’s what we do know:
Toriel was always interested in the occult from an early age, often experimenting and reading about it, which carried on until her adult years, which did lead to the reason of Toriel changing her name from “Torialias” to “Toriel” as she wanted to Elvenize her name as she had a very strong interest in them.
Toriel developed an intrigue in humans ever since she first met one when out and about with her mother, a stray human was walking alone picking berries and offered Toriel some, this kind interaction made Toriel sympathetic to humans and very interested in how they work and communicate.
Toriel was introduced to Asgore, they had a decent first interaction.
As soon as Toriel learned how to read, Toriel become very interested in reading, writing and storytelling
Toriel developed a close relationship and built a good rapport with Semi Sheriffs
Teen years:
Before 1010, Toriel met and started to get to know a human by an unknown name and started to become friends with them, it’s unknown about the specifics, but we do know that this was the same human who killed Alexander during Toriel’s betrothal, we also know during this time Toriel expanded her research into magic and started to hone her skills, which did eventually evolve into her ability to mix magic schools together. In 1010, Toriel was introduced to Wingding for the first time, they didn’t get along so well, at first but they didn’t hate each other, the big rift between their relationship was a mix of Wingding’s loner personality and Toriel not liking that her personal bodyguard is some little kid who is 4 years her junior, but they continued to tolerate and put up with each other and continued to do so throughout their time together.
As Toriel was nearing the age of being old enough to be betrothed to someone, Toriel’s parents were quite busy deciding on a suitor, which left Toriel often to her own devices with only Wingding keeping her in-line, which wasn’t easy as Toriel was a very rebellious teen, after escaping Wingding’s watchful eye (which to be fair was likely not that hard seeing that Wingding really didn’t want to have to watch her) Toriel went to communicate to her human friend, we don’t know what the conversation exactly entailed but it somehow influenced them to kill Toriel’s father Alexander Dreemurr, either on purpose (if Toriel didn’t ask the human to kill anyone) or by accident (if Toriel asked the Human to kill Asgore and they killed the wrong person). Eventually Asgore was picked as Toriel’s suitor and they got betrothed to get married in an arranged marriage when Toriel turns 18 (and will take the throne when she becomes 25).
During the ceremony, the human killed Alexander which, viewed as an act of aggression, Jazzimine retaliated, which was the first domino that fell that eventually led to enough things transpiring that it resulted in Monsters and Humans going to war together.
Near the end of the war, while monsterkind was near victory, Toriel snuck out, what her true motives were she never told, however whatever she planned backfired as it resulted in her capture and ransom, which resulted in Monsterkind despite whipping out 90% of humanity to lose the war and be sent underground in 1015 ACE.
Toriel took over the throne in 1022 ACE, not many details is known about what happened between then and when they adopted MK, but we know that Toriel had a rocky start and huge shoes to fill, and she did eventually reach political stability when exactly is unknown but it was during the time she hired J.A River as the royal scientist. Toriel developed a close relationship with J.A River and viewed River as a trusted friend and not just an employee.
In 1901, MK was orphaned and then adopted by Toriel and Asgore as their own, then in 1910, Frisk fell down and was adopted by them as well, however MK’s death and Frisk’s corruption in 1912 lead to the divorce of Asgore and Toriel, in a fit of rage she sent out an immediate death order against any human who falls underground and put a huge bounty on Asgore’s head, which caused him a deep seeded level of emotional turmoil as he went into hiding in fear of his life. It was here, Toriel declared war on humanity. Though despite the hardships she faced, Toriel continued to rule with wisdom and compassion, earning the respect of her people.
In 1935, J.A River dies, which takes another massive toll on Toriel’s mental health considering her a close friend causing Toriel to go into years worth of mourning which, mixed with finding a suitable replacement difficult made finding River’s replacement take a lot longer, which her life before the 1970s, was made up of a lot of close calls off almost dying of sadness but she managed to pull through using the love she has for her subjects. It all changed in the 1970s when she first met Sans and developed a close bond with her. It gave her hope and motivation to keep on going in life, not just for others but for herself. Which eventually led to her falling in love with him, which led into the two getting married in 1996.
Tragically, Toriel's reign came to an end on December 3rd 2015 when she was slain by Chara, a human child who had fallen into the Underground. Her death had a profound impact on the Underground, leading to a civil war and plunging Monsterkind into chaos.
Toriel’s consciousness and soul now lives on inside Chara, acting as a phantom only Chara can see, Toriel guides Chara, helps Chara use their newfound powers and tries her best to keep Chara safe and sound.

Example: let’s say, hypothetically Person A is down to 5 HP and has 2 def, while Person B currently has 10 HP and 3 Def, B will use Parasitic Symbiote to give them a shared HP of 15 and defense of 5, any attack on either of them takes HP off their combined HP score instead of their individual scores, meaning if A then gets attacked with an attack dealing 6 damage, instead of taking 4 damage draining A’s health to 1, A and B take 1 damage and their joint HP goes down to to 14.
Trivia:
Toriel loves to bake, particularly pie.
Toriel's favorite food is escargots and likes snails in general, but when it comes to an animal she likes but doesn't eat, she also likes mice
Toriel dislikes Squirrels
Toriel and Wingding have a bit of a strained relationship due their opposing personalities (Toriel's wish for unity and order vs Wingding's individualism, chaotic menace to society and ID embodiment) and grew up with each other, Toriel marrying Sans didn't make it any better and Wingding is very "WHAT THE HELL, SHE'S MY AGE! I GREW UP WITH HER! SHE IS 4 YEARS OLDER THAN ME! WHY IS SHE WITH MY SON?!?"
Toriel has a minor drinking problem and often gets drunk with Sans
While Toriel does consider Frisk their child and was her heir at some point, due to Frisk being a human, legally speaking, Frisk is Toriel's pet
due to Toriel being killed by Chara while Sariel was a baby, Sariel doesn't know Toriel
Toriel didn't want Sariel's name to be Arrus, resulting in that being her middle name instead, though Sans does have a preference in calling Sariel by her skeleton name "Arrus" which Toriel never really liked
Toriel is multilingual and speaks most monster languages present in the underground, besides just Monstarian (the main monster lanaguge that all monsters know in some regard)
Toriel was very much aware of Napstabot being a ghost inside a robot's body and hired Undyne on her tech genius
While Napstabot and Toriel don't view themselves as related, legally, Toriel is Napstabot's mother/stepmother as Sans adopted him
She loves to garden and has a large garden.
Toriel is into the Occult
Toriel is the only character that we know of that can mix together Magic schools
When Sans and Toriel fight together there is an occasional chance that when Toriel does an animation where she leans forward Sans will goose her or pinch her butt causing her to jump and look at Sans disapprovingly with a light blush as he winks and laughs, eventually smiling back at him and then returning to her original position
Orginally this was just going to be a post with the Sw!Fallenswap Gaster brothers just showing off the two really different clothing styles associated with that decade, but then I got a bit carried away. (As evident by the fact the 80s ones are lot more polished than the other ones)
2 of them have an alternate version, that version has details that they have in present day and not during that time period, so basically if they were to wear it today what would they look like. I also don't know if Sans is dressed too femininely in the 80s one, as I looked at both male and female clothing references.
Kudos to you if you know which two subcultures Sans' outfits are based off of in the photos above!
hints, or if you already know the answers, fun facts: 1 - though the subculture started in the 70s, it was very popular in the 80s, 2 - though this subculture is usually thought of to started in the 50s, it first appeared in the late 40s.
I found a website/computer program that can make vocals for lyrics that is actually free so I decided to make a song for Sw!Fallenswap Napstabot in it because I already have lyrics for it
I forgot the name of the site, but originally I was going to use it for Napstabot's theme I made them, but it doesn't let you import music, so... Yeah.. anyway, there are some graphical errors in the video, it's a GLITCH with Wevideo NOT something I can fix, (trust me it wasn't there when I was making it only there after I exported the video), also it didn't let me add transitions to every change in lyrics ever since they updated the site, so if you are wondering why some have transitions and some don't that's why.
also I tried my best to crop out the water mark, so you're welcome.
Sw!Fallenswap by me
Notes about Video if you are interested:
There was originally more at the end which was going to be for a short animation but I ran out of attention span to add that last part, anyway it was going to have the music go off, Napstabot getting concerned and instinctively taking a defensive stance to protect Chara, then it shows Undyne was the one who interrupted the song by coming on a big screen TV, which then Napstabot takes offensive stance, as points his fist towards the TV, with the compartment on the back of Napstabot's hand opening showing the small missile looking things they have inside of it. (Yes, if you noticed, Napstabot uses both He/him and they/them pronouns)
Here's the uncut audio if you want to know what the originally planned animation part would sound like: https://drive.google.com/file/d/1YGB7XjsocGnqxrEj494vM5-y-DbD_wqi/view?usp=drivesdk
Also his theme that the lyrics were originally going to be made for: https://drive.google.com/file/d/1TUpof-Qw-AlSVWQNYw8DR_vV4-s9GB7N/view?usp=drivesdk
Can we see more characters from UTY if they were in Sw!Fallenswap? (I think you're Ceroba design and AU's lore is very cool btw)
Sure and thanks! I'll even expand on each of them, though none of it is 100% canon to Sw!Fallenswap, and thought up quickly as they aren't canon.
I couldn't settle on a Azimuth Dalv design but I did make a pacifist route Starlo design, he reminds me of a power ranger for some reason? (It's probably the mask.)
I had to do some math to get it to fit in the Timeline, get everyone's ages and get Martlet's life expectancy and to get Dalv's persumed age by finding the life expectancy of a Fox Anthropomorphic (there is an equation I use to find life expectancies of all the Anthropomorphic races) to see if it lines up in the timeline for Kanako's grandparents to be alive in 1013, as that is the most notable year in the timeline where Anthropomorphics did kill a bunch of Undeads matching Fallen!Dalv's description on why he has beef with the Ketsukanes (though Dalv never mentioned a year). The life expectancy number came out to be 950, then by adding Ceroba's age of 39 (assuming either Ceroba or Chujin's parent(s) had their child near the end of their lifespan) minusing it by 1985, got me 996 which did check out timeline wise.
Character notes:
Clover Notes: Clover doesn't change much from their UTY appearance, changes are they are much more verbal, Clover can save and load, doesn't have Flowey/Temmie because Temmie wasn't made animate until the 90s and they carry around a Polaroid Camera (which was very popular in the 80s), which there are certain spots that you can take a picture of giving you the Achievement "Picture Perfect" and doing them all gives you the achievement "Photographer's Eye"
Clover will become a Myling with the other souls and kill Ultra Temmie in Chara's non-canon neutral ending still. Clover is one of the 11 characters known to be from Gen X.
Unlike Genocide UTY Clover, Genocide Fallen!Clover does die still, due to Sans ripping Clover's heart out and eating it before Clover was able to shoot Toriel, meaning the Clover’s Genocide Route in Sw!Fallenswap could technically be canon if it wasn't directly stated Sans only killed Patience, Bravery, and Perseverance.
The fact Sans was able to sneak up on Clover implies he was expecting Clover to show up, even though Clover managed to enter the castle undetected, so it's likely Dalv conversed with Sans beforehand.
Since Temmie didn't exist yet when Clover was alive, you can wait for Asgore to drop a rope for you gaining the Achievement “Patience is Virtue”, which will cause you to skip the Martlet fight and proceed like normal Undertale except you have to sneak out of ruins which is difficult but worth it as you also skip most of Snowdin as well, because Papyrus saves you from Sans and teleports Clover away, Papyrus gives you a medallion and tells Clover to show it to Dalv and say “Papyrus sent you” which can skip the Dalv fight (if you so wish) which will get you straight to the portion of attempting to travel to Hotland, the medallion can actually also be used to instantly spare MOST random encounter enemies which will give you the achievement “VIP”
If you don't wait for Asgore to drop the rope the playthrough plays similarly to UTY, but without Flowey or Temmie, if you do a genocide route Dalv won't shapeshift into a wolf and swim you down the river, instead The Boatman (Wingding Gaster) does, but Clover still ends up falling off the dam, but instead of Sans causing a wave from striking a bone wall into the water, Wingding purposely knocks you off the dam knowing what you did.
Either way, you wash up on a Dunes’ shore on 1 HP, which makes the medallion very useful to have if you waited for Asgore to return and got the medallion from Papyrus as it can instantly spare most enemies, so you won't get killed by them before you reach a save point.
Martlet Notes: She's a hermit that lived in the ruins before they were abandoned, she met Chujin before and due to her age she is old enough to have met the Integrity soul who fell down in 1936. She likes jigsaw and logic puzzles, as well as reading textbooks.
She's the only known character from the Cavalier Generation. Her personality seems to be a blend of her original personality and Dalv's
Dalv notes:
Dalv (or Sir Alucard by Ceroba and Officer Alucard by Starlo) His personality is similar to his original and Martlet's, the most notable difference between his personality and UTY!Dalv’s personality is that Fallen!Dalv has much more of a spine when it comes to advocating for himself and speaking his mind, he is much more willing to stand his ground and overall is much more brave, he is also much more willing to use profanity, albeit not in English, usually in Romanian or Monstarian when speaking to another Monster (adult monster that is, as he doesn't swear at children).
Judging by the fact he is stationed in Snowdin but doesn't wear the Snowdin Guard Armor, means he was either off duty when he ran into Clover or not apart of the Snowdin police force, but he is also not wearing a deltarune so being off duty is more likely.
He has beef with The Ketsukanes due to Kanako's Grandparents role in the 1013 Mass Undead Racial Cleansing, but doesn't have that same resentment towards Kanako as she tried to right the wrongs. Judging by the fact Dalv mentioned having parents and a younger sibling, it means Dalv is either a traditional variant (parents are the Elden Variant) as Elden Variants are naturally spawned, or Ancient variant if his parents were Ancestral Undead (once Elves)
Dalv is seen to shapeshift into a bat and a wolf before, bat when trying to escape with Clover and when they dropped over a waterfall and a wolf when swimming in the river with Clover on his back to try to get to Hotland.
As a Vampire, like all Undeads, he does have telekinesis and teleportation, so in his fight Blue Soul Mode is used for some attacks. Instead of Puzzles in Snowdin, he sets up riddles due to his love of storytelling.
It’s implied Dalv likely conversed with Sans before the Azimuth Dalv fight due to the fact Sans was able to ambush Clover before Clover could kill Toriel, which isn't unlikely as they are both on the royal guard and Dalv seems to be on a first name basis with Sans as Dalv said “Sans, you're a tâmpit!" instead of “Sir Gaster, you're a tâmpit!” (tâmpit which in this case means "asshole" in Romanian) when Sans causes Dalv and Clover to get washed over the dam, this is notable because Royal Guards only refer to each other by first name if A.) They don't have one (which Sans does, it's “Gaster”) or B.) They are on frequent speaking terms outside of the Royal Guard, this means Dalv and Sans must converse frequently outside of guard duty to know each other's first names.
Genocide phases:
Dalv is in his normal form, and his fight is a harder version of his pacifist/neutral fight
When Dalv gets low on HP he injects something (either DETERMINATION or SPITE) into himself, which turns him into Azimuth Dalv
Once killed Dalv's Shade spawns, like all Shades in Sw!Fallenswap, it has high attack and defense but only one HP, meaning you have to do all the shots perfectly with the wild revolver to actually kill him, any mistake won't be enough damage to get through the Shade's Defense.
He seems to inject himself with either DETERMINATION or SPITE at the end of Genocide, due to the fact in that scenario DETERMINATION will turn a monster into a Draugr and races in the Undead Monster Type will not have that reaction to DETERMINATION but neither would SPITE as it creates a Shade after dying and doesn't put them into a temporary state, so it's unknown what caused that reaction, but it's still likely SPITE instead which explains why Dalv was able to handle it so easily and not melt as SPITE destroys light mana in a Monster’s soul while DETERMINATION melts it, but since Undead Souls have Dark Mana instead, SPITE doesn't harm their soul. It also explains why phase 3 Dalv is a Shade. It is also more likely to be SPITE instead of DETERMINATION, as that would be easier to acquire, only way Dalv would get his hands on DETERMINATION is if he extracted it from Undyne, though he does know her, Undyne would likely try to stop Clover herself. The way Dalv could get his hands on SPITE would be extracting it from Sans or another Undead, though Dalv did call Sans an asshole and Sans did cause a massive wave which caused Dalv and Clover to get washed over the dam and fall into the Dunes area in a Pacifist and neutral run, Sans would likely be willing to extract SPITE from himself to give to Dalv, and not go and fight Clover instead like Undyne would, as he is more likely to stay at New Home to defend Toriel which Sans does successfully in Clover's genocide run as he does very graphically and violently kill Clover.
Starlo Notes: he seems to work with Ceroba in some way, despite not being in the royal guard, he is either a part of the boomer generation or Silent generation in the case Starlo is a year older than Ceroba. Like his original counterpart, he had a crush on Ceroba and knew her since childhood, though unlike his UTY!Counterpart as he doesn't have this North Star Persona, he is more open about his nerdy side and seems to be rather intelligent when figuring out how to defeat the robots in Steamworks. Since Starlo has no attachment to Kanako's robots, killing Axis or Guardener will not abort the pacifist route, he's just relieved you made it out okay.
His personality is similar to UTY, but his temperament seems much more like UTY!Ceroba, he injected Chujin with the serum made from the Kindness Soul, because Chujin tricked Starlo into injecting Kanako's concoction into Chujin thinking it as harmless leaving Starlo into believing he accidentally killed Chujin, but he never told Ceroba this. Starlo also only tries to kill Clover as a mercy-kill-last-resort type thing because if Clover makes it to Toriel, Toriel will burn Clover alive resulting in a painful death, if Clover isn't handed over to Toriel, Clover will die of heart failure due to vitamin D deficiency, and if Clover somehow manages to kill Toriel the underground will possibly go into anarchy, so Starlo attempts to kill Clover in Pacifist route realizing these 3 outcomes.
Ceroba notes: Ceroba (or Sherif Ketsukane by Dalv) is an abrasive personality, and unlike UTY!Starlo she is affiliated with the Royal Guard, as Sherif and Dune's Police Chief are the same occupation in the Dunes region of the Underground, and unlike UTY!Starlo but like UTY!Ceroba, she has an antagonistic role. Ceroba will lash out at Clover if you kill Starlo, but Dalv will call her out as a hypocrite, as she was willing to condone murder of other people's loved ones, causing a short altercation between the two, which Dalv does end up over powering Ceroba pushing her off the edge, which she survives after being found by some other royal guards.
Kanako Notes: Kanako was an intern, to whomever J.A River's Successor and Undyne's predecessor was and got cryogenically frozen, due to Undyne being non observant and the true lab access keycard being lost, it's unlikely Kanako will ever be found.
Kanako got her internship at 14 years old by submitting her idea of Steamworks to be a backup power supply if the core ever breaks, the robots were made in collaboration with a younger Undyne who was also an intern between 16-18 years old at the time.
Kanako wanted to make amends with Dalv Alucard as her ancestors killed his family during a massacre and wishes to right that wrong, which makes Kanako the only Ketsukane that Dalv doesn't have beef with.
Chujin notes: Very little is known about Chujin other than he tricked Starlo into administering the serum and that Chujin was a stay-at-home parent, we also know he's not a boss monster like he was in UTY, as Boss Monster is a specific race of Monster and not category. We also know like Ceroba and unlike Kanako, he is unwilling to try to make amends for his ancestors wrongdoings in the 1013 Mass Undead Racial Cleansing, as implied by what Kanako said to Dalv, further supported by Ceroba's predisposition of hating Dalv. We can assume he had a lot of faith in Kanako's abilities as he was willing to try her concoction on himself, which ended his life and due to Undyne not being the Royal Scientist yet, he wasn't used in Undyne's experiments and died in hospice.
