Leviathan

**Leviathan** (リバイアサン, *Ribaiasan*) is the Demon Lord of Envy and one of the Seven Deadly Sins.

## Appearance

Leviathans demon form appears to be mixture between her human and true form. Her upper body is that of a weak little girl. She has blue hair with beatiful hair accessory. The accessory consists out of two shells at the bass with two starfish atop of each other. The one on top is nice shade of red, this same starfish is also on the back of the accessory. It has a piece coral sticking out of it and there are a few pearl strings. She has green and blue eyes and around her neck are gills. Like all demons she has fangs, fins as where her ears should be (Usally hidden by her hair) and wears what looks like an one-piece swimsuit. Around Leviathans waist is what looks to be her mouth from her true form. While this part seems to serve a bit like clothing, it does seem to be made out of her own flesh, as a functional tail is also attached to this part. While her upper arms are humanlike they disappeared into the mouth and come out the waist. In a way her lower arms seem to have long gloves on. This part is a lot bulkier in comparison with the rest of her body, she also has scales on top of her hands. Leviathan's legs are human like with the exception of her feet that have fins around her ankles and black toes.

Her human form appears to be a little girl. Almost identical to her demon form, but with no demonic attributes. She still wears the same hair accessory as in her demon form and also wear a cute black dress.

In her true form she's, simply put, an monsterous, humongus fish. She's whale like with three rows of teeth and six huge fins, three on each side of her body. She as even more fins close to her tailfin, these are a lot smaller than the other six. Just two on each side and a backfin. Also her tailfin is a horizontal, like a whale. Leviathan is so big in this form that a normal sailing ship is the same size as one of her teeth. The top and side parts of her body is also covered in scales that are so hard not even Boy's miracle sword could penetrate it. Her underside seems softer with vertical lines from her mouth to her tail. While the outside of her body is sturdy, her insides are a lot softer.

## Personality

Leviathan is, like her appearance, very childlike. A very happy-go-lucky girl that likes to play games and might even be called a bit naive. In reality however, Leviathan is a very lonely individuel who secretly hates herself. She hates her large, hefty body that makes everyone afraid of her, so much so she even envied birds and their freedom. All she wanted was friends, she even changed her own appearance to that of a weak, little, human girl to do so. Up until the moment before she fought with Boy, she never accepted herself. Once she did she became more happier.

She calls herself mama, because god told her to be one. Her job is filling the oceans with sea life, so she sees all of her offspring as her children. She cares for them a lot, even though she has never raised one of them. Leviathan kicked and punished Mammon when he possessed her cute little orca and even when she eats fish she would hold her stomach and welcome back her children. She can be motherly as she was the one who raised Imuri.

## Abilities and Powers

### Enormous Strength

As the ruler of the sea Leviathan is blessed by the lord himself. Giving her so much physical strength that she has to be very aware of it. If not she could accidentally break something or hurt someone.

### Shapeshifting

Leviathan can freely change her form between her true, demonic and human form. She can even transform only parts of body. For example she can let her arm and hand grow to a gigantic size.

### Birthing Sea Life

She can give birth to all known sea life. This includes: Whales, Orcas, Krakens, Octopi, Sharks, Jellyfish, Crabs etc.

### Demonic Power Supression

Like Asmodeus she can hide the presence of her and other demons demonic power.

### Water Manipulation

As a creature of the sea Leviathan can control and manipulate water. She can create huge tidalwaves and even send a blade of highly pressured water towards her enemies.

### Regeneration

When heavily damaged she can regenerate her body back to normal.

### Miracle

Being a creature that was blessed by the lord himself she can use a miracle, namely **God's Power Shown in Creatures** (Job 41:21). With this miracle she can shoot a super heated flame beam (basically a laser of some sort) from her mouth. This is has so much heat and range it can cook live fish just by being close to it and melt/destroy a satellite up in space.

### Portal Mouth

Leviathan's mouth is a gateway that leads straight Gehenna, anything she swallows will end up in Gehenna. When a demon is swallowed by her she can interact with them as they fall to Gehenna.

## History

In the beginning when God created the world he created Leviathan and told her: *Be fruitfull, and multiply, and fill the waters in the sea...* (Genesis 1:22). In other words: Leviathan was responsible to fill the seas with life. Giving birth to all sea creatures big and small.

But over the years Leviathan began to despise her large body, as it made everyone afraid of her. So much so she even envied birds. She longed for companionship, but her children pointed out that she is so strong no one in the ocean their could be her equal. That's why she took the form of a weak little girl, so she could be accepted by humans. To be among them and be their friend. Sadly this didn't work. While she could change her appearane, she did not take account her physical strength. She scared sailing humans when she boared their ship, accidently destroying part of it. They saw her as some kind of fairy that sinks ships, even though all she wanted was friends.

At some point after she became a demon lord.

### Part 1

While not fully appearing Leviathan is mentioned as one of the three demon lords Boy has yet to encounter. She makes her first proper appearance towards the end of Part 1. Kicking a weakend Mammon for taking control over her cute little orca. When it's seems Mammon is not apologetic about it she gives him a 'spanking'. After, she complains how it's not fair that Asmodeus, Mammon and even Beelzebub all went to play with Mr.Priest. Not wanting to miss out on all the fun she decides to go meet Boy.

### Part 2

After her decision to meet Boy she's seen travelling in the depths of the sea, where sunlight doesn't reach. Traveling with all kinds of sea creatures (who are also her kids) including a smack of jellyfish who give off light. She reads the book "Leviathan" by Thomas Hobbes in Japanese. She mentions how the Japanese language is so mean because in the kanji for envy, the character for woman appears twice.

When her children found out that she was planning to meet Boy and become his friend, they tried to stop her. After that she apparently got on a cruise ship that collided with a giant octopus which caused her to wash up on shore near the villa Boy, Imuri, Leah and Barbara where staying.

After being taken in and put in a bed by the quartet, she explains how she washed up on shore. Telling them a convenient story and omitting any hints about her true identity. When asked why she calls herself mama she tells them the truth that her father (god) told her to be one. While this comment started to trigger Boy, she gives the finishing blow that she would bear his child as thanks for saving her. Confused as why everyone tenses up after what she said, Imuri takes he outside for some fresh air. On the beach Imuri asks Leviathan what her plan is, which she answers to be friends with Boy. She tells Imuri she won't give away her Imuri's identity and talks about why she believes a friendship between her and Boy is possible. As Imuri's wants to protest this plan, Leviathan teases her by saying if she could still call herself Femme Fatale if her mama stole her man away from her.

After their talk on the beach it's decided that Boy, Leah and Barbara will take turns taking care for Imuri and Leviathan. While she's happy about hanging out with boy, she doesn't notice that a hermit crab saw them. Said hermit crab misinterpreted the situation and calls upon his stronger siblings to rescue their mother.

Later Leviathan is seen waking up from dream about her past. She has a talk with boy about being strong and the possibility of being friends with those weaker than you. For the next days she lives with the other four playing games, laughing, eating and just having a good time in general. Leviathan feels happy and whishes this feeling could last forever, but during diner her children arrive to 'rescue' her. They reveal her true identity and Leah gets confirmation from the church that she's indeed not human. Realising she lost her chance of having friends she flees the scene, heartbroken, followed by Leah and Barbara.

Out on sea Leviathan cries over what just happened, but is interrupted when Leah and Barbara arrive to fight her. Leah asks if she could beat her, the lord of the sea, would she be strong enough to beat the lord of the flies. While still feeling upset Leviathan creates a tidal wave, wanting to wash it all away. Leah succesfully stops the wave with her miracle, so Leaviathan decides to use physical force. She is however stopped by Barbara who blinds her, giving Leah the chance to use her miracle to manipulate the Leaviathan's blood, tearing her apart from the inside out. After a quick regeneration Leviathan takes on her demonic form and easily overwhelms the two nuns. Deciding to leave she delivers the final blow, but her attack is stopped by Boy who just arrived with Imuri in the nick of time. As Leah and Barbara leave with Imuri, Boy and Leviathan are ready to face off .

Before they fight, Leviathan talks how it's unfair everyone around her is so weak. She cries telling boy she never wanted to be born strong. That she's feared for being so strong, that no one can be her equal. But Boy says he's not afraid of her. Leviathan asks him if he would still accept her even if she's not a weak, little girl. He says that as a demon lord she doesn't need his acceptance. Realising she only had to accep herself, Leviathan feels happy and takes her true form before fighting Boy. He takes hit after hit, but is swallowed whole after deflecting Leviathan's miracle **God's Power Shown in Creatures** (Job 41:21). Boy is able to save himself by cutting Leviathan from the inside out, leaving her with an enormous wound.

After that Leviathan decides to head home, but not before offering the Boy her help once if he's ever in trouble. Boy rejects the offer, but Leviathan doesn't mind and shrugs it off with a smile. Before she truly leaves, she helps out Imuri by saving both her and Boy.

### Part 3

She's seen with the nephilim Golem at the end of Part 3.

### Part 4

She seen watching Aria's performance from her phone, under the sea.

Later Leviathan appears again in a flashback, when Boy feels insecure about himself.

After Asmodeus was swallowed by her, Levithan comments that she was wrong this time and asks her fellow demon lord if she got her heart broken.

## Relationships

### Children/Followers

While other demon lords have demons and humans as their followers, Leviathan has her children. She cares for them a lot and in return they are extremely loyal to her. They constantly worry about her wellbeing and follow her because of her love and tyranny.

### Imuri Atsuki

While Leviathan did not give birth to Imuri she was still the one to raise her. As such they have some sort of mother-daughter relationship.

### Asmodeus

Asmodeus is seen with Leviathan during Imuri's flashback to her time as a child, during which the two call each other by nicknames suggesting they have a friendly relationship.

## Trivia
