Leviathan is pangender (any pronouns) and pansexual. They are 5’7” (173.736cm)
Levi has extremely bad social anxiety, and living in the house with their father definitely fed into it. They never learned how to advocate for themself or ask for help until after the Morningstar children (and Simeon) all moved across the country. Even though they did learn how to, it’s still very difficult and they only really do so when around their siblings. They didn’t face a lot of issues related to their father head on since they were extremely subservient to him. Seeing Lucifer and the others being abused made them afraid to do anything out of line. They are not particularly close with their mother.
Since the divorce and more so after the move, Levi has been able to explore anime and manga more thoroughly. Their love for it stemmed during childhood via Ghibli movies and it’s only grown. Although Lucifer was a bit picky about which games they played at first, Levi also got to play video games and fall in love with them. Both of these lead into their skills in makeup, sewing, programming, wig sculpting, art, and more. They also began to take Japanese since the beginning of high school and like practicing with Barbatos and Asmodeus.
Engaging in their interests helped Levi feel a bit less like they are devoid of personality, but their social anxiety is still quite awful. Their stammering has improved, but holding conversation is difficult, especially with new people. They do livestreams on the weekends and feel much more confident behind a screen, which has helped ease it a bit as well.
Levi is particularly close with Asmo since they shared a room growing up and were often locked in for hours at a time. Mammon often put Levi in charge of Asmo when things got violent, especially when Asmo began to show signs of mental illness later on. They don’t hang out as much in tech school because of Asmo being more outgoing, but Levi’s still in charge of keeping them in check when the others cannot.
Levi is in (online) tech school for computer programming and game development. They own programming socks and a Blåhaj. (And of course, a fun pleated skirt.)
That’s it for Levi! There is probably plenty that was forgotten/will be added in-fic!!
Satan is just a li’l guy (for most of his appearances). He is 3’5” (106.68cm)
Lucifer had Satan prematurely (“very preterm”), so he was very small and had a few complications after birth. There are lifelong complications as well.
Satan often gets bullied at school and has only a couple friends (which rotate because he has trouble socializing). He gets irritable easily, especially in social situations. At home he is relatively cooperative, even when he asks a plethora of questions. He loves to read and learn.
Satan is especially attached to Mammon, Levi, Simeon, Asmo, and Barbatos since they often take care of him when Lucifer cannot. Even when Lucifer is home, he often is exhausted and will pass out on the couch or has to attend to other responsibilities in the house. This is usually when Satan turns to one of Lucifer’s siblings for attention and help.
In the mornings on weekdays, Levi will bring him to Simeon and Barbatos’ place to be watched over. On the days he has school, Simeon will escort him there and Lucifer will pick him up. Simeon and Barbatos do their best to follow Lucifer’s rules (not exposing him to certain media, not giving him too many gifts, not brushing off his curiousity, etc). Barbatos also ends up teaching him to speak in different languages a little bit since he will switch between different languages without realizing every once in a while.
That’s all for Satan! Like with the others I’ve probably left out plenty/more will come up in-fic!
Asmodeus is genderfluid, using they/he/she pronouns as they are needed. They have bracelets to indicate pronouns: purple (they/them), blue (he/him), and pink (she/her). They are demiromantic multisexual. They are 6’1” (185.928cm)
Growing up, Asmodeus was often berated and sometimes physically abused by their father for being feminine. They were often mistreated or bullied at school as well, and it took a huge toll on them. When they began to show signs of their mental illness during their preteen years, the bullying and abuse only worsened, which in turn fed their mental problems.
Being left untreated made it more difficult for Asmodeus when they realized they were gender fluid, because they were afraid it would be brushed off as mental illness (despite gender dysphoria not being a mental illness). Lucifer encouraged them to be themself when they came out, which eased some of their problems but also caused others. They attempted suicide shortly after beginning high school and since then have repeatedly refused professional help.
Asmodeus wanted to be friends with Solomon as soon as they met in high school, but didn’t initiate anything since their confidence was in the ground. Solomon ended up noticing them in theatre and they became friends extremely quickly, constantly sticking up for each other. They both have a crush on each other but are afraid to ruin their friendship, so they haven’t attempted to be more than friends. The suicide attempt made this even more of an issue, because Solomon doesn’t want Asmodeus to assume a romantic relationship is out of pity. It has been years and it has remained this way.
When the Morningstar children (and Simeon) moved across the country, Asmodeus was finally able to engage in their interests. Theatre, ballet, singing, art… Lucifer encouraged them to do whatever they wanted, so long as they weren’t hurting themself or others in the process. When they were a child, Lucifer would sometimes teach them some ballet when their father wasn’t around, and ever since then, they wanted to be in a proper class. Being able to express themself through their artistic interests improved some parts of their mental health, but also ended up getting them bullied still. It’s mostly a win, but sometimes it can be a source of discouragement.
Asmodeus looks up to Lucifer and Barbatos a lot, since they are artistic influences in their life. This kind of sentiment has been around with Lucifer for longer, but Barbatos’ success in the music industry makes Asmodeus think of them on the same level (if not Barbatos slightly more so). Not to mention Barbatos’ androgynous appearance makes them extremely jealous and they find him beautiful.
Asmodeus went into tech school for cosmetology. When they are not studying beauty, they will be studying pagan belief and witchcraft with Solomon under Barbatos’ mentorship. They also became a member of CLAIRVOYANCE and took over as lead singer when Barbatos had to step out.
That’s it for Asmodeus!! I’m sure there’s plenty that is left out/going to be added in-fic haha.
Trigger/content warnings: mention of Mammon and Diavolo previously being purely sexual/a sugar baby and sugar daddy relationship but nothing NSFW. A single joke about “getting dick”
Headcanons/notes from the author: I honestly edited a good chunk of this for this upload because it was so messy lmao.
Brief Blurb: Mammon and Lord Diavolo reflect on things together.
The Devildom's nighttime cycle had begun, and Mammon yawned into his hands. It was cold for hell, but he didn't mind it. The cooler weather was a nice break from the usual warm temperature. He sat on the balcony of the demon prince's quarters, watching Barbatos water the flowers a few stories below. It was peaceful for him to not worry about anything for a while, especially since Lucifer was on his ass about everything recently. "Mammon?"
He smiled at Diavolo, who had come and sat next to him on the couch. "Hey." The two were only reaching their second month being an official couple, and Diavolo had made it clear to Lucifer that there wasn't a reason to be worried. "Do I have to go home tonight?"
"Is Lucifer still being mean about things?" Diavolo held his hand and tilted his head. "I could speak with him again, if you like."
"It's not really that as much as it is... well..." Mammon sighed and stared at his boyfriend's hands. "Y'know, Lucifer is probably still all butt hurt we didn't say anythin' about... our previous arrangement." Diavolo chuckled. "I-It's not funny! Jeez..."
"Aw, c'mon, it's a little funny. I mean, what's he so worried about anyways? He's courting two people, it's not like he's worried about you getting more dick than him." Mammon spluttered, a little uncomfortable with Diavolo's phrasing. "Anyways, I think you should talk to him, if anything. Maybe he's just worried I'm going to give you an STD."
Flustered, Mammon told him, "Maybe... but I doubt it..."
"I don't know, maybe he's bothered since it's not Asmodeus doing this." Diavolo ran his fingers through Mammon's hair, then kissed his temple. "It would probably be more in character for Asmodeus to be flirting with the demon prince."
Mammon shrugged. "I mean, ya fucked him before, didn't you?"
"Sure, I mean, he's the avatar of lust, after all." Mammon was going to interject, not liking that statement at all, but kept his mouth shut. "Though he was feeling pretty vulnerable, so maybe I should have made him think it through instead..." He chuckled and kissed Mammon, then added, "I simply hope he doesn’t regret it."
"Kinda hard not to when Lucifer is on his ass about it." Mammon made a strange noise when Diavolo pulled him into his lap. "I think he might be better off just stickin’ with Solomon for a while."
"Mm..." Diavolo ran his fingers through Mammon's hair, humming as he did so. "Maybe you're right." He gave Mammon a kiss, then nuzzled into his neck. "It's not that big of a deal."
They sat there quietly, staring out at the garden and enjoying the other's presence. It had been so strange before, when it was a strictly sexual arrangement... but now that they were allowing feelings, Mammon felt more relaxed. Sure, he had denied any desire besides sex and money beforehand, but that's just how he was. A complete scumbag in his brothers' eyes... but Diavolo understood it, or at least he could provide both in return of what he himself wanted.
For a long while, there was only the sound of their breaths and the plants' fluttering leaves. They felt like it was hours, but in reality it was only a short while. "My lord, Lucifer is downstairs. He wishes to speak with you."
Lucifer is a trans man (he/him) and on the aroace spectrum. He is 5’5” (167.64cm)
As a child, Lucifer was expected to be the “perfect little girl” his father (Adam) wanted. He took ballet under his stepmother (Evelyn)’s influence and was encouraged by Evelyn to learn violin when he showed interest (his father did not approve of this at first). He studied hard, participated in choir and theatre, as well as the aforementioned activities, to the best of his ability. He was able to do those things because his father believed he wouldn’t disobey him whatsoever, which was partly true. Lucifer often put Mammon in charge of keeping the younger siblings hidden/distracted while he took everything head-on when things escalated. Lucifer would often freeze up and rarely fought back or moved without outside help, which also became his instant response when he has a flashback or triggered to a certain degree. It’s become easier to help him come back to the present over the years, as well as reduce his freeze response.
After Evelyn divorced Adam and was given full custody of all the children, Lucifer and Mammon did their best to make up for Evelyn’s neglect. Despite being a relatively kind woman, Evelyn found it difficult to be present and didn’t care for her children very well, which didn’t change after the divorce. Once Lucifer turned eighteen, he took custody of his siblings and fled with Simeon to a more progressive area.
Lucifer had Satan unexpectedly when he was 22. Satan’s other parent (Ariel) gave him sole custody after they broke up when Satan was about six months old. Despite the reason for breaking up, they are on relatively good terms. Lucifer will send her pictures of Satan from time to time and she sends money around Satan’s birthday, as well as major holidays. Lucifer doesn’t talk about her very often, and Satan doesn’t know much about her.
Lucifer just graduated veterinary school and works at a vet clinic. Animals adore him, and Satan enjoys the stories about the cats he sees at work.
That’s all for Lucifer! There’s plenty left out/forgotten/added within fic!
Mammon is a trans man (he/him) and pansexual. He is 5’4” (164.592cm)
Mammon, like in-game, is intelligent but lacks the focus to do well in lots of things. He’s often bored or overstimulated by his surroundings and won’t get a lot done, which was an issue growing up. He was often berated and physically abused for these things, along with his “unladylike” behavior (playing in the dirt, roughhousing, interest in cars, etc). While Lucifer most often got in the way and took the physical blows for him, this often resulted in Mammon being locked by himself in a closet or room for hours. He is extremely afraid of small spaces, and that knowledge being used against him only made it worse.
After the move, Mammon tried multiple different outlets for his energy and ended up following Lucifer’s footsteps into theatre. He often got lead roles, but has not continued participating after high school. He likes to help Beel practice volleyball when he gets the chance. Instead of continuing education after high school, Mammon began to work full time to assist Lucifer (and Simeon) with finances. When he’s particularly stressed and can’t think of anything else to do he’ll take Cerberus on walks or jogs. He takes good care of all the cars, too!
In particular, Mammon is most close with Lucifer since they were watching over their siblings and doing their best to keep them out of harm’s way. He doesn’t remember their mother since she left shortly after he was born, but he likes to hear the vague snippets Lucifer has of his toddler age memory, even if they are mostly grasping. The two work together on finances since Mammon is excellent with numbers, and he is often researching the cheapest food or items they can get in particular stores.
Mammon has had a few short lived teenage romances, although after his last one in particular he has been avoidant of anyone who says they have a crush on him. He has a few friends, but he’s often responsible for the family when Lucifer cannot attend to certain things and that prevents him from doing much with them outside of texting.
That’s all for Mammon! There’s plenty left out/forgotten/added within fic!
Headcanons/notes from the author: originally the requester wanted transmasc MC but I ended up making it pretty neutral. It reads more as a binary trans reader instead of anywhere in between, though. Mentions my main trans headcanons for obey me.
Brief Blurb: MC is very dysphoric and skips lessons.
You had found yourself completely unable to leave bed. That morning, you texted Lucifer that you were sick and didn't want anyone, including himself, to come bother you. Surprisingly, he had fulfilled your wishes completely. You heard the brothers leave the House of Lamentation about an hour after you awoke, meaning you were all by yourself.
Despite not wanting to be bothered, you did get rather lonely just playing on your D.D.D. in bed. After a few hours of laying, you were also hungry on top of being lonely and dysphoric. Eventually, you reached for your two-sizes-too-big hoodie and put it on while remaining underneath the covers, then slinked out of bed.
You opened your door, then nearly jumped out of your skin at the sight before you. Lucifer had pulled up a chair against the wall opposite your door, and passed out in it. You figured he had been waiting there since this morning, but this meant he hadn't left to attend R.A.D. with the others. Since when did Lucifer skip lessons?
He was stirring, probably from the noise your door made when you opened it... so you panicked and just left the door open while hurrying downstairs towards the kitchen. Once you got to the fridge, you opened it and dug around for a snack. There wasn't a whole lot left, probably because Beel did before and after breakfast snacking. Eventually you decided on just taking the vegetable plate that they had bought you not too long ago, thinking you'd like human world food to be around. While they weren't wrong about that, it wasn't exactly the food you had in mind... so it kinda just sat there for a month.
Just as you were about to head back upstairs, you realized Lucifer would definitely wake up if you returned to your room. Sighing, you brought your veggie plate to a corner in the kitchen and sat there, eating very quietly. "There you are."
You startled and nearly choked on your food. "Lucifer!?"
"I did not intend to frighten you, I'm sorry." He frowned a little, rubbing sleep from his eyes. "I just... noticed you left your room..."
"Y-Yeah..." You sighed and stuffed another vegetable in your mouth.
"I can give you space, if you still want that."
For a few seconds, you didn't say anything. Then, taking a deep breath, you shook your head. "No... I would... like your company."
Giving a small smile, Lucifer came over and sat across from you on the floor, grimacing a little. "Why are you on the floor?"
"Mm, I thought maybe you were still asleep..." you muttered. "I didn't want to bother you. You're always so exhausted, and I feel embarrassed of myself..."
He furrowed his eyebrows. "Why are you embarrassed of yourself?"
"Well..." You fumbled with your food, considering telling him the truth. "I'm not... exactly in a good headspace right now."
Hesitantly, he told you, "I assumed that was why you said you were sick." You felt your face grow hot, feeling silly for not thinking about how he would figure it wasn't a full truth. "While I know you are a human and I am a demon... you can still talk to me about things. I raised my siblings, and I've been around a long time... there's a lot more I might understand than you think."
This was something you already knew, obviously. Just as you knew Mammon and Levi were transmasculine, and Asmo was genderfluid, and that Barbatos and Simeon were non-binary... It was as if he could tell you were trans and scared to come out. "I feel stupid..."
"That... wasn't my intention."
"I know, but I still do." You sighed and set your food aside. "I know you won't care if I tell you what's bothering me... but I was in the human world all my life. Things aren't... nearly as nice about what I want to tell you."
"Darling, I don't want to pressure you into telling me if you aren't ready to."
"I want to tell you, though. I feel so dumb being scared when I know you won't be upset." You shyly crawled to him and sat next to him, only to have him pull you into his lap. Flustered, you snuggled into his chest. "Lucifer, is it okay if I tell you?"
"Of course it is."
You took a deep sigh, relaxing into him as he cupped your cheek and rubbed his thumb against it. "I'm trans..."
"I know." He chuckled. "I'm assuming you aren't out in the human world?"
"That's right..." you told him quietly. "I'm so scared..."
He hushed you and scratched at your scalp. "You don't have to be scared here. We love you as you are." Hearing that from him seemed to touch a part of your heart that made you burst into tears. This alarmed him, quickly adjusting himself to see your face. "Did I say something wrong?"
"N-No, you made me happy..." you mumbled, hiding in him. "I love you so much, p-please don't ever change..."
He chuckled, kissing your head. "I love you too. Do you want to tell the others yet, or just me?"
You sniffled and muttered, "Them too."
Smiling, he rubbed your back and kissed your head once more. "As you wish, my love."
(Since @obeythedemons said I should go on a headcanon tangent dhskdhd)
(This is a lot longer than I thought it would be because I’ve thought about how his past might be so many times [and started a fic that I never finished about it], but I think it reads okay…? I also used some in-game/Karasu twitter stuff to align certain things with canon. Very nervous dhsldh)
(Also, it’s written like… timeline format. Ehekdhdk)
TW/CW: mentions of physical harm, rat bites, death threats, spoilers for season 3 (lesson 41 onwards)
I can’t remember when, but at some point in game it’s said that Barbatos was never a child (or something along those lines). I like to imagine (especially because Luke existing proves that angels and demons typically grow up similarly to humans) he was, but it never felt like it because of his powers. Being all-knowing, able to destroy every timeline and realm if he did something incorrectly would have caused him to feel like he grew up too fast. I imagine he didn’t really have a family (either because demons are usually similar to angels in being procured and choosing their family or his family realized his powers could have grave consequences and did not want to be held responsible). For his childhood, he was going between nobles as a servant because while he could alter reality however he liked, he was mostly focused on not damaging the realms.
The nobles Barbatos worked for constantly reminded him how dangerous his powers were, to the point he was afraid of himself. He worked mostly on repressing his powers and not properly controlling them. The premonitions in his sleep (mentioned to be canon by Karasu’s twitter) became frightening for him. He could find books on portals, but since it was only one aspect of his abilities (and not much was known about his timeline aspect of it), there was only so much he was willing to try. This made nobles extremely frustrated with him, since they wanted to use him to their advantage. He used his other skills to appease them (baking, cooking, sewing, et cetera) and keep himself off the streets.
This lasted until he was entering his teen years, and he decided he wanted to utilize his powers to help others (which was also a way for him to test how well he could control them besides repressing them). He started out with going behind his masters’ backs and giving people insight into their futures once he found a book on foresight. It quickly was discovered that he was doing so, and escalated into him having to find new places to go to escape the nobles that wanted his powers to be used for themselves. He hated being used in this way, and became a Robin Hood of sorts. He would go to homes in the human world and Devildom of nobles and rulers, then steal from them to bring more those in subservient positions like he was in.
He was able to get away with it quite easily for a long time due to his portals and premonitions, but since he was still learning there were things he was never sure of or simply confused himself with. He could never get into the Celestial Realm no matter what strategy he used, and eventually his attempts to get in were being talked about among lesser demons. While his attempts to enter the Celestial Realm were already enough to make him infamous, he was also trading foresight for places to live and other things he needed to survive. This lead to the Demon King wanting his arrest when Barbatos was in his late teens/young adulthood. He made a single slip up and was captured.
The Demon King had already been on shaky ground with the other realms, so Barbatos causing problems in the human world and attempting to enter the Celestial Realm had him extremely angry. Not to mention he wasn’t very kind in the first place, especially after the death of his wife. He used Barbatos as an outlet for his anger, and Barbatos could not escape due to the Demon King having chains that prevented his powers from activating. It was then that Lord Diavolo (also in his late teens/young adulthood) met Barbatos, and he began to speak with him whenever his father wasn’t around to find out. The two began to form a loose friendship through Barbatos’ stories and Lord Diavolo’s kindness.
Although Barbatos was used to cruel nobility of the Devildom, no one had physically harmed him to the same extent the Demon King had. Not only this, but his fear of rats became increasingly unbearable the longer he lived in the castle’s dungeons. They crawled on him, bit him, chewed on him, and he couldn’t get them off with the immobilizing chains. He had to endure it until the Demon King arrived (which scared them away) or Lord Diavolo snuck in to visit and could shoo the rats away.
When the Demon King found out that Lord Diavolo was speaking with his prisoner, he was extremely angry, threatening to destroy Barbatos. Lord Diavolo admired Barbatos and certainly didn’t want him destroyed. In an attempt to keep Barbatos around, he began to beg for Barbatos to be his butler after his father agreed to not destroying him if he was subservient. Eventually he threw his uncharacteristic tantrum (mentioned in game) declaring that he would not become the next king unless Barbatos was his butler. It was then that Barbatos (having no way to foresee what this would do outside his sleep premonitions before being captured) gave his word, and signed a contract bound not only to the Lord Diavolo, but the Demon King. He was forever bound to both and could not break the contract on his own whim.
The contract took away most aspects of his powers being used without permission from Lord Diavolo. He was allowed portals, and couldn’t control his sleep premonitions. The contract also erased many of his memories from before, in an attempt by the Demon King to make him more subservient and less likely to attempt to escape the contract. Knowing that he couldn’t completely rely on Barbatos’ powers being fully repressed by the contract, he made them painful to use without permission (which applied to sleep premonitions and any attempt at remembering his past before being a butler).
Lord Diavolo, while attempting to find ways to “put the king to sleep”, also found documents that may help Barbatos further in controlling and utilizing his powers without fear of destroying timelines and realms. Since he couldn’t practice without permission, Lord Diavolo would give him set hours to do certain things. Eventually Barbatos became well versed in his abilities outside of his portals. The Demon King was put to sleep.
When Solomon summoned Barbatos successfully and they formed a pact, Lord Diavolo was ecstatic. It was a foot in the door for harmony between the three worlds, but also a way to unbind Barbatos from the Demon King while still searching for a proper way to break the contract. After ensuring he could do it correctly, Lord Diavolo gave Solomon the Demon King’s spot in the contract. This also gave Solomon full control with the pact instead of the initial limitations that were in place due to the contract’s existence. Shortly after this, Barbatos entrusted Solomon with his grimoire, allowing Solomon to know his past without Barbatos having to tell him.
By the time the exchange program began, Barbatos still is bound to the contract and has his limitations. However, he recognized MC immediately from his sleep premonitions and his ordered foresight sessions.
(I probably forgot some other headcanon junk but uh. There we go!)
