— Genesis's feelings for her quirk

 **User(s)** | Genesis Elpis

**Eradicate** (絶やす, *Tayasu*) is an Emitter Quirk that allows the user, Genesis Elpis, to create weapons out of keys.

## Description

Looking like just an ordinary key, Genesis quirk is quick to fool anyone with first looks. She prides in this and uses it to her advantage, usually giving people a shock with a large weapon appears with a twist of a hand. The weapons that come out of the key follow the same look with a colour scheme of green and black. The weapons can be anything really, from bows to scythes to swords, the keys have a great choice but it is finding a key that lasts. Not all keys excite her but she has found out that the greater the make of the key generally creates a greater weapon (so a plastic key gives her junk while a strong metal key usually gives her a decent weapon). Once a key has been found it turns into a weapon with a flick of her fingers, the kinetic energy giving it its form, and the key itself turns black. It is just a matter of finding a good key.

Genesis creates her weapons by twisting her keys and a small blossom of fire spreads as the key expands into a weapon of black and green. Genesis is able to do the same to make the weapon turn back into a key. While in it's weapon form, it doesn't weigh anything more than the original key weighed making the weapons light and easy to use especially since Genesis hasn't had the training to be able to carry the weapons she carries. This allows her to move the weapons freely with little energy needed to be used to move and twirl the weapons. It is why she is so skilled at wielding her scythe, also known as Patéras. The weapons are also a lot larger than Genesis. This may be because she is rather small or just in general of the weapons being larger than most. The swords and guns being bigger than most things similar to it while the bow is about the same size as Genesis. She hasn't been able to see if her scythe is really bigger or not due to very little people actually using a scythe as their main weapon of choice.

Though Genesis only uses keys, she is able to use any small object as long as it has iron and/or silver in it. The iron and silver react with Genesis kinetic energy and so it could be said that the quirk is to do with the kinetic energy she creates rather than changes forms of keys. Since Genesis has never been taught how to use her quirk and she has self-taught everything, she has no idea about the *real* limits and strengths her quirk has. Though saying the weapons are prerecorded, they are actually made up by Genesis owns thoughts. In some way you could count Genesis as a weakness to this quirk seeing as she is holding the quirk back but she has done well exploring her on her own so far.

The main problem with this quirk is to do with its usage. With each use of her key, it becomes rusty making the weapon and key fragile and eventually becoming weak as a weapon itself. Since the key *is* the weapon, any damage as the weapon is done to the key so if Genesis plans on using her keys to open doors she must ensure they don't break or get broken while in weapon form or part of the key will break or chip away. The key does have more durability than the weapon, with a larger part equating to a smaller part of the key, however, cutting the weapon's blade/main part off will cause the part of the key that opens doors to be broken completely, leaving her with a stump. Any damage done to the key will stay damaged until fixed, this doesn't include the weapon though and instead just makes the weapon much more fragile.

Genesis' keys can also break by overusing her quirk. When her quirk is overused her weapons slowly start to break themselves until they shatter into different sizes of pieces. This also shatters the key making it impossible to be able to use that weapon again since each key is individual. She can get the same weapon again but it will be different in style, use or durability. This is just like how a key will never be an exact copy of the original.

## Abilities

**Activation** (活性化, *Kassei-ka*) is the term for when Genesis transforms her key into a weapon. The "science" behind her transformations is actually quite simple. Genesis uses kinetic energy - by twirling her key around with her fingers - to generate an ignition. In some ways this is her quirk instead, her kinetic energy igniting instead of generating electricity. This ignition can be used on any objects but instead Genesis only uses it on keys since that is how she grew up to know of her quirk. Once the key is twirled and has enough kinetic energy to ignite - each key having a different amount needed, usually smaller weapons needs less ignition - the key starts it's transformation into a weapon. Genesis keeps twirling the key until it becomes a full weapon for which she now can use against someone. Genesis could use anything to activate the key, as long as it was her own kinetic energy, but she finds her activation method with her hand is much more subtle and easier to do than anything else she has tried.

Activation is rather simple at heart and is something Genesis does easily and unknowingly at times. Once in its' weapon form it is required for Genesis to move the weapon around but since she is usually calling it to train or the fight someone, she has never had any bothers with this and is hardly a weakness in her eyes. It's just simple playing with her weapon to keep it a weapon and not a key. To deactivate, Genesis needs to get rid of the kinetic energy in the key so she usually loses contact with the weapon and lets it lay. Without it touching her it quickly reverts back to a normal, black key.

**The Awakening** (覺醒, *Kakusei*) is the name that Genesis gave to the events that happen when she uses a key for the first time. Unlike the many other times Genesis uses her keys the transformation is rather dramatic. Large orange flames and black smoke appears to come out of the key and take a form of a monster or God/Goddess as a personification of the key. From all the smoke and flames the key is transformed into a weapon. It is slow and different from the usual process to turn a key into a weapon but it is activated in the same way. Once Genesis kinetic energy reacts with the key it bursts into the orange flames that usually cover the weapon for a few seconds. It could be said this is why the key is black, almost like it is burnt, due to the flames that is created during the Awakening Process being immense and hard for even Genesis to handle - each time she seems to jump back when using a new key. The weapon looks like any weapon, just it has a black and green colour scheme, but the key, with it's black form, gains a unique pattern on the top of the loop which allows Genesis to tell which key she is using. The patterns are usually shapes such as stars.

### Strengths

* Genesis is able to carry weapons in form of keys
* Can appear and disappear at will
* Light compared to real weapons
* Each key is unique

### Weaknesses

* Overuse makes key and weapon shatter
* The more use a key gets the weaker the weapon (from rust)
* Damage done to the key is done to the weapon(and vice versa)
* The quality of the weapon depends on the key itself

## Keys

### The 4 Titans

**Ρεα** (Rhea, *Rheia*) is one of the four main keys Genesis uses. The key takes the form of a bow. They key was originally a key for a locket and is actually the smallest key she owns making it a lot easier to find than most. The weapon is rather simple but in looks it is one of the most interesting and appealing to look at. Genesis has used this key once but has transformed it, from key form to weapon form, a lot. It is rare for her to fire her bow and usually she simply threatens with it in hand. Rhea is one of the few keys that Genesis doesn't feel comfortable with using as it does a lot of damage, with the arrows being explosives.

The key is black and has a five-pointed star on the loop. The titan, Rhea, was said to be the mother of the Gods and Goddesses and Genesis remarks her bow as the mother of all weapons, steaming into great danger. The weapon is where most people have interest with it following the colour-scheme of the rest of the weapons it is mainly black. Two green circles, looking a lot like eyes, crowns where the arrow sits. The arrow has a green point. When Genesis takes this key out she has only one shot with one arrow. Despite only being shot once, Rhea is on its' last legs, with much of the structure of the bow looking rather rusty. This is because of the power the key has and the arrow acting like the key. If Genesis shoots the arrow, the bow transforms back into a key after the shot. The key usually lies where the arrow was shot. This means the key can be inside someone if the arrow pierces.

**Κρονος** (Kronos, *Cronus*) is one of the four main keys Genesis uses. The key takes the form of a sword - more accurately, a katana. The key started off like most keys, made of silver. Unlike the rest of the **4 Titian** keys she doesn't know where this key actually goes too. Having taken it from one of her many babysitters over the years it was the first key that Genesis had stole and she felt great sorrow for doing so. Despite being one of the four main keys Genesis uses, she has only used this key twice. Once was during it's **Awakening Process** while the other was when she falsely believed it was her scythe in Athens, Greece.

The key, like every key Genesis owns, is black and has an eight-pointed star on the loop. Unlike Selênê and Ôkeanos, Genesis didn't think of a reason to name her key this. With having three keys named after titans she thought this key would also be named after the titan and why not the father of all the titans. As Kronos is the titan of titans. Though the weapon is simple in design and is mainly of green rather than black, it is one of Genesis' personal favorite, just for its' sheer looks. It is one of the few weapons to have brass on it, since most are only metal and black and green.

**Σελήνη** (Selênê, *Selene*) is one of the four main keys Genesis uses. This key is known to turn into a gun, a sniper rifle to be exact, being black for the most of it and having vivid green details it is the most unique weapon in its colour scheme compared to the rest who usually follow a regular pattern. It is a weapon that isn't used in many battle situation but she holds onto dearly due to the many situations it can help her out. It was created from a key her mother handed to her. It opens up a house not too far from her fathers' where she can stay in her father became "undependable". This is the first ever key Genesis was given and thus became the first key which helped her discover her quirk. Despite this, she has barely used it and, as such, it doesn't have much rust with only a tiny bit to be seen on the actual key itself. None can be seen on the weapon.

The was like any key. Made of silver it isn't the best in quality but is highly vestal and strong enough to be a key. It hands, like most of her keys, on her wristband. The silver colour, just like all of her keys, has disappeared and instead took on the form of the black iron key that so many take. No longer is sleek and rather modern and small but it is large and old-fashioned. Somehow it still fits in the lock of her apartment which she still doesn't understand how it is possible due to the lock being a different age than the keys' looks. The key is called Selênê because of her mother handing her the key, her quirk is to do with the moon shining, but also because she feels like this key is exactly how her mother feels. She feels like shooting a bullet through her fathers head! Selênê is also the name of the titan of the moon in Greek mythology. The key seems to have a four-pointed star in the middle of the loop.

**Ωκεανος** (Ôkeanos, *Oceanus*) is one of the four main keys Genesis uses. This key is known to turn into a scythe with the handle being black and the blade being the vivid green all weapons have. It is her first choice weapon in any battle situation and as such, could be the called the main key of the main keys. It was created from her fathers' key to his basement - where he holds all his experiments and where he is found most of his days -and is the second key to be from this. The first key was also a scythe but was of a lesser quality after the first one broke easily. Karen made another key for his basement in a greater quality of key with a mix of iron and silver. The silver was more to do with a coating of the key which disappear when the key went to it's normal black iron form. Since this is the most used key of hers it has gathered a bit of rust though this can't be seen when she takes out her weapon much as it is on the handle. With the key it is much more apparent as it covers about a quarter of the key.

The key was rather old-fashioned but is one of the best keys in quality if it isn't for the rust. It was created by Karen after her last key breaking so easily, with the thought that she may break or lose her key again, he created a wristband and the key to be a greater quality than the last. This is why this scythe has lasted longer and is better in combat than her last version. Since the key has transformed into a black iron key the silver coating which once was on the key has completely disappeared but that doesn't bother her. Her father has noticed that the key looks different and that she has gained more keys on her wrist since the band was created. The key is called Ôkeanos and for the effort, she usually shouts the name of this key without realising, it is not necessary the make the key into a weapon and is just added for flair. It is named Ôkeanos because: it is her fathers' key and is known to be much like the ocean, still and quiet but can quickly turn into a storm, and it is is the main weapon used to protect her father from harm. Ôkeanos is also a titan of the earth in Greek mythology. It is this weapon that is considered the "classic" weapon of choice for her. The key seems to have a six-pointed star in the middle of the loop.

### The 6 Goddesses

**Ενυω** (Enyô, *Enyo*), named after the Greek Goddess of war and destruction, are two minor keys that Genesis uses. It takes the form of knives and its keys have a part of a rosary on its design at the loop. It is the only weapon which she has a copy of and as such duel-wields the two.

**Βια** (Bία, *Bia*), named after the Greek Goddess of force and raw energy, is a minor key that Genesis uses. It takes the form of a spear and its key has an arrow on its design at the loop.

**Ελπις** (Elpis, *Elpis*), named after the Greek Goddess of hope and Genesis' second name, is a minor key that Genesis uses. It takes the form an axe and its key has an apple on its design at the loop.

**Ιρις** (Iris, *Iris*), named after the Greek Goddess of the rainbow and is the messenger of the Gods, is a minor key that Genesis uses. It takes the form of a baseball bat and its key has a batwing (the animal) on its design at the loop.

**Ἡβη** (Hêbê, *Hebe*), named after the Greek Goddess of eternal youth, is a minor key that Genesis uses. It takes the form of a broadsword and it's key has a horn on it's design at the loop.

**Αφροδιτη** (Aphroditê, *Aphrodite*), named after the Greek Goddess of love, beauty and pleasure, is a minor key that Genesis uses. It takes the form of a frying pan and it's key has a lizard on it's design at the loop.

* The author felt the twirling of the fingers to activate the key into a weapon was highly fitting due to them having the habit of twirling their pen when bored or thinking.
* If you are unable to tell, the main four weapons Genesis uses is named after Greek Titans while her 6 other weapons is named after Greek Goddesses.
* Aphroditê has a lizard as a design on the loop which is a hint to the movie Tangled by Walt Disney.

* The arrow on Βια symbolizes Pyrrha, from RWBY, emblem.
* To date, this is the best quirk the author has created in her eyes.
	+ This is also the largest quirk the author has created as well as being the largest on the wiki.
