Quirk: Split Personality Quirk manifest (Subconscious Quirk Maker)

Type: Emitter

Based Idea from: Legion (Marvel) and The Hord (Split/Glass)

User Idea: Izuku Midoriya

His Quirk allows him to manifest a separate personality who will have their own view, desires and capabilities. Each personality created will manifest a personal Quirk that represents their personality.

Each personality is born under different circumstances that Izuku will find himself in. the personality and Quirk manifested is dependent on his experiences and thoughts.

If both Izuku and more than one personality wishes for a Quirk to help them with their circumstances, then a weaker or limited Quirk will be created that have no personality attached to it. Izuku could call them Personality remnants.

I like to think that most personalities are close to Izuku and wish to help him.

Drawback: Izuku won't have complete control over the personality's they are each a different individual. Izuku can't always control it when a personality takes over his body.

He can't access a personality's Quirk without the personality attached to it. In battle he will need to switch over to a personality that suits the situation best.

If Izuku is forced into an unresponsive state, then a random personality will be forced in control and may course problems for Izuku and those around him.

Example – ifHitoshi uses his Quirk on Izuku a personality will be forced into control overhis body.

Personality and Quirk Ideas/Examples

Personality Remnant -001

Quirk: Dream Ink

Description: The Quirk allows the user to produce a white like substance that can transform into any accessories. Depending on the desired clothing it can change colour.

Drawback: The user must have a very clear imagination of what they wish to wear. Dream Ink does not allow them to create weapons or support gear no matter how clear the thought is.

How/When it was made: It was made soon after Izuku created a personality that wished to wear something very badly.

Quirk: Personality separation

Description: The Quirk allows Izuku to separate his multi personalities from his mind in the form of a clone of Izuku. Combining this alongside Avatar is a powerful combination.

Drawback: The Quirk only separates personalities from Izuku not make clones of Izuku. How many clones Izuku can make are dependent on how many personalities he has.

How/When it was made: It was made an out of the personality's wishing to interact with the world alongside Izuku instead of relying on him.

Personality Remnant -003

Quirk: Avatar

Description: The Quirk allows the user to change their physical form into the form they desire the most. The form can be any shape, size and form the user wishes.

Drawback: The use can't shapeshift into someone they know exists. They must have a proper view on what form they wish to take.

Usage: The way the personality's use Avatar to help them alters depending on whether they are separating form Izuku or not.

True Form: Is the form the personality few themselves at.

Avatar possession: When in possession of Izuku the personality will alter Izuku's body slightly usually be changing the eye and hair colour, if needed his gender and physical capabilities.

A personality can alter Izuku's body into their true form if they wish but they avoid that because of the strain it can putt into Izuku's body.

Cloned avatar: When a Personality separates from Izuku they automatically take on their true form.

How/When it was made: It was made from the personality's wishing to take the form they call their true form. It can help the personalities utilise their Quirk better.

Personality 001: Name: Jeff – Quirk: Full Access – Gender: Male

Based Idea: Stain

Description: Jeff believes that everyone must earn their wright to have a Quirk by utilising it the best they can not matter how Weak, Strong or useful the Quirk may seem.

Jeff believes that the weakest people are those that rely entirely on their Quirk and neglects their own physical capabilities. He hates seeing people use their Quirks for completely selfish reasons and looks up to those using their Quirk the best way they can.

Example – He hates Endeavour and Bakugo because they wish to use their Quirks entirely to prove authority. He likes Aizawa and Mei for them using their Quirks to help people not caring about popularity.

Personal Capabilities: Jeff's Physical capabilities are more agile and stronger than Izuku's, Jeff has the best battle awareness than any personality.

Quirk: Jeff was originally Quirkless like Izuku, but he had pride in it because it will just push him into training. It was only after a decent amount of personalities were created (2 or 3) that Jeff's Quirk Full Access manifested.

His Quirk allows him to access any Quirk owned by a personality without having the personality attached to it. He may not be able to use a Quirk to its fullest capability's because the personality that owns it is only able to.

Their Birth: Jeff was made from Izuku's strong desire to still protect people despite being Quirkless but really wished he had one.

Jeff was born when Izuku tried to protect a kid from being bullied by Bakugo.

Story Idea involving the Personality: Jeff becomes active during the Battle Trial to show how weak Katsuki is against him.

Quirk (Knowledge is Power): Data's Quirk allows him everything about a persons Quirk by consuming a bit of their DNA via Blood, hair, sweat or saliva.

When gaining enough knowledge of a Quirk's capability's either from his Quirk or by learning it himself Data can gain an immunity towards some Emitter type Quirks.

Example – If Data learns everything about Hitoshi's Quirk Brainwashing and fights him, Hitoshi's Quirk won't affect him.

Drawback: When activated his eyes become cloudy and he goes on auto pilot while righting everything about the Quirk down on paper. He is unable to acknowledge anything going on around him in this state and he's unaware what he's writing down until he reads it himself.

Data was created after Jeff from Izuku's deep desire to know more about his own Quirk as quickly as possible.

Gretel: She has more agile physical feats that Izuku and more energy to use.

Quirk (The Moon's Love): Hansel's Quirk allows him to produce his own darkness that he can manipulate at will. The strength of his darkness increases in the darkness. Darkness from the absence of the sun is much more effective than shadows created by the sun or cloudy days.

The darkness has the capability to consume and store anything he wishes without doing damaging it if he wishes.

Drawback: his Quirk is reliant towards darkness that is in his immediate area and in contact with him.

Any form of light will weaken his Quirk, but natural light is much more affective compared to artificial light. When daylight comes his Quirk is completely cancelled and anything, he may have stored into his darkness will be forcefully removed.
