Requip, a quirk with the only known user Izumi Midoriya.

Overview: This quirk allows the user to use different armor sets. Each armor set gives its user a different quirk, multiple armor sets can be stacked to use multiple quirks at once. A summoned companion comes with each armor, with their abilities depending on how the armor was created. Requip also has the ability to sense life-threatening danger, allowing its user to protect themselves at all times. Due to the abilities of this quirk, the user may be underdeveloped or in Izumi's case a bit short because their body must adapt to have multiple quirks.

Armor type: Natural. A natural armor is created when the user is in life-threatening danger or overflows with emotion, so more effective with females(not sexist). Any natural armor's abilities, suit, weapon, and companion depends on the situation they were built to prevent. Any changes can only happen during a battle where the armor evolves to adapt to a situation.

Armor type: Artificial. An artificial armor is created by the user. Any of the armor's abilities, suits, weapon(s), and companion are built and designed by the user but can be modified into an armor or be used as a template for a natural armor to evolve from.

Super Move: Overdrive. An ability of all armors to limit break in a sense. Essentially, all powers of an armor are enhanced for a short duration of time. This can only be used 3 times a day, without permanent disabilities. Most versions of Overdrive are some sort of fusion between the user and the armor's companion. Due to this fusion, the armor adapts more to the user and evolves and becomes stronger. When using overdrive, only one armor may be equipped.

Available Armors

The Master Armor

Natural type. This armor was created when Izumi pushed past her limits, note that this armor is constantly growing stronger as Izumi grows and becomes stronger.

Quirk: Elemental Manipulation, this quirk allows Izumi to control all the major and minor elements. Although the armor puts major stress on Izumi, the quirk has no side effects. She can use this control as sharply or roughly as she can but requires complete concentration for a more accurate control.

Companion: Any of other armors, while wielding Aegis Blade.

Weapon: Aegis Blade, also any other weapon she has. The blade allows her to use any weapon, quirk, or companion from another armor while being wielded.

Overuse: Use of this armor causes major stress on the body, depleting stamina and possibly causing Izumi to pass out and permanently injure herself.

God's Guardian

Natural type, created when Izumi wanted to protect a kid who didn't develop their quirk yet.

Quirk: Divine Guardian, this quirk allows Izumi to create divine constructions that can take any form and can be controlled within a 100-meter radius. Izumi can also enhance her body to increase her strength, defense, and speed. Using this quirk too much causes Izumi to have headaches that turn into migraines.

Companion: Cybele, a guardian angel created solely to protect and assist her mistress Izumi Midoriya. Cybele is a wielder of the Divine Guardian quirk as well.

Weapon: Divine Blade, an unnamed blade that works especially well against those with intentions deemed unholy or evil (example Mineta's perverted issues), although doesn't work against those who are pure of heart, examples being those like Izumi or are extremely innocent like Eri.

Overuse: this armor makes Izumi more innocent and caring to those around her. If you used beyond a certain point, Izumi will become an angel for a brief time and unable to change back, from prior experience she had a halo and a small pair of wings for a week.

Flaming Passion

Natural type, created when Izumi wanted to save Katsuki from the sludge villain and was surrounded by burning villains.

Quirk: Fury of Fire, this quirk allows Izumi to control flames whether created by Izumi or someone else. While Izumi is also able to create her own flames, she can also absorb heat and someone else's flames to strengthen her own. Izumi's flames also become stronger and harder to put out when Izumi becomes angrier. Using this quirk too much causes Izumi to overheat, she will pass out if she doesn't control herself.

Companion: Pyra the Flaming Beauty, a human girl created to help Izumi and save the lives of others alongside her, she and Izumi recognize each other as partners. Pyra and Izumi share their emotions with each other which strengthens the Fury of Fire quirk.

Weapon: Flaming Claymore, a blade that can be lit on fire when being wielded, but will not light when not held by either Pyra or Izumi. Works well against most enemies, but is less efficient in colder environments, works even surrounded by water.

Overuse: this armor makes Izumi more sensitive to anger and makes her slightly bipolar. If used beyond her limitations, Izumi's body heat will be higher than normal for a few days to a week in some cases.

Swift Strike 

Artificial type, created by Izumi for speed and swift attacks, but lacks defense.

Quirk: Adrenaline, this quirk was created by Izumi to strengthen her as a battle continues. As a battle lengthens, Izumi will become stronger and faster the longer she fights, but she will become extremely tired after the battle is finished, to the point where she may faint.

Companion: Takuya the shadow demon, he desires to protect Izumi from harm to the point where they will merge, making Izumi a demon for a short period of time. Takuya can hide in the shadows and summon fellow demons to protect their Izumi-hime.

Weapon: Shadow Blade, a weapon that can reform as the user wishes, reacts to Takuya or Izumi. Works well in darker places and at night, but weakens severely indirect daylight.

Overuse: this armor makes Izumi emotionless, and pale. If used without limits, Izumi will burn in sunlight similar to a vampire, but clothing can prevent the pain for a short period of time.

Deadly Defender 

Artificial type, an armor made by Izumi to protect her allies and civilians, while able to cause major damage when needed.

Quirk: Terraform, this quirk allows Izumi to reform the Earth around her, this is limited to dirt, sand, and stone. Izumi is able to create weapons and even cause a sandstorm or earthquake. Overuse of this ability will weaken Izumi's physical body making her more vulnerable to attacks.

Companion: Poppi the Android Defender, Poppi sole mission is to protect the innocent. Poppi can terraform the earth to her bidding with only the risk of falling apart. 

Weapon: Drill Shield, a shield with a drill in its center. A weapon able to quicken Poppi's and Izumi's terraform ability, while also able to take earth to enlarge to drill or shield.

Overuse: this armor causes Izumi to be a bit overprotective and calmer in different situations. When used without limitations, Izumi's body will become solid stone for a short period of time.

Silent Spy 

Artificial type, Izumi created this armor to gather intel and for surveillance.

Quirk: Network, this quirk allows Izumi to connect with her companion Index and see whatever they see. This also allows Izumi to store data in her eyeglasses (they come with the armor).

Companion: Index the polymorph spy, Index can clone herself and turn into various creatures, ranging from humans to her favorite cat form. Anything Index records can be recorded in the Astral Plane and accessed through Izumi's glasses.

Weapon: Deceiving Daggers, a pair of purple and black daggers. These daggers allow Izumi to turn invisible and be controlled by her mind.

Overuse: this armor causes Izumi to become more shy and reclusive. When the glasses overload with information or the daggers become unstable, Izumi will grow cat ears and a cat's tail for a few days to a possible week.

Sea's Princess

Natural Type. This armor formed when Izumi almost drowned while surrounded by dozens of villains.

Quirk: Guiding Wave, this quirk allows Izumi to control water around her. When there is no direct water around her, she can collect vapor or hydrogen and oxygen atoms to form water. Also when Izumi is in the water she becomes a mermaid and is slowly healed while in the water, but note that her regeneration cannot heal major wounds instantly.

Companion: Levi the leviathan, Levi can control water and breath smoldering hot or freezing cold water, like a dragon breathing fire, but this ability is less effective while in water.

Weapons: Holy Star, either a white staff with wings and a star on its tip or a golden trident with a star where its prongs meet. This weapon helps Izumi's accuracy and potency when controlling water.

Overuse: this armor makes Izumi dehydrated easily and have a superiority complex. If used without restraint, Izumi can't go without water poured over her skin for half an hour, this only last for a day.

Symbol of Hope

 Hybrid type, mixed with One for All. This armor formed when Izumi's body finally accepted One for All.

Quirk: One For All, this quirk stockpiled 9 person's strength into one quirk. Allowing Izumi to use near the impossible strength for one person.

Companion: Nana Shimura, the seventh wielder of One For All. Nana is Izumi's personal sensei and guardian to help her with controlling One For All.

Weapon: None.

Overuse: this armor has no side effects, but the quirk may leave lasting injuries if not used in consideration. 

Crystal Covenant

Artificial type, created by Izumi to replicate Shoto Todoroki's ice quirk, but sturdier and less overbearing on the body.

Quirk: Crystallize, this quirk allows Izumi to summon crystals into many formations for multiple uses. Using this quirk to much will create crystals along Izumi's body that she can dispell over time or by force.

Companion: Emilia, the crystal dragon. Emilia is Izumi's familiar that allows Izumi to use her as a mount and shield or weapon.

Weapon: Crystal Cleaver, a blade that cancels the side effect of the Crystallize Quirk and can be reformed using the same crystals.

Overuse: this quirk makes Izumi more stoic and emotionless. I used beyond a certain point, Izumi's body will turn into solid Emerald for a brief time.

Frost Fear

Natural Type, formed when Izumi's mother, Inko Midoriya, died and she fought Spinner while going through a surge of sadness and misery.

Quirk: Frost, this quirk allows Izumi to form ice for multiple purposes ranging from weaponry to making platforms. Using this quirk too much freezes over Izumi's body, much like Todoroki's half-cold.

Companion: Wulfric, the frost wolf. Wulfric can control ice, control his size, and create clones of himself.

Weapon: None, Izumi can create weapons made of ice using the Frost quirk.

Overuse: this quirk gives Izumi a more cold personality, but if used too a certain point Izumi's body will become ice for a brief time.

Umbran Beauty

Natural Type, formed when Chisaki's and Eri's quirk activated on Izumi at the same, exact time.

Quirk: Umbran Magic, this quirk works with the spells and weapons Izumi may wield. Basically, this quirk allows Izumi to heal rapidly and become a part demon for a short period of time. While also allowing the use of contracts with multiple demons, but this ability is quite limited unless in Overdrive.

Companion: Mirage, the shadow bird. Mirage can create illusion and is powerful enough to create tornadoes with a few flaps of his wings, while his talons can crush steel like it's nothing.

Weapon: Various Weapons, these weapons attached to Izumi's feet and held in her hands can be infused with magic for certain effects. Izumi can also chant magical spells in this form. Each weapon is crafted from a restless demon, each with different abilities.

Overuse: this armor gives Izumi a seductive personality like Midnight. Although use without restraint causes Izumi's body to become more 'desirable' or 'mature' so to speak, this effect may last days to sometimes a week.
