"*I am happy... to be of service.*" - KOS-MOS

## Profile

### Identity

Archer's true identity is **KOS-MOS** recursive acronym for Kosmos Obey Strategical Multiple Operation System, An android designed for combat against the Gnosis, mysterious beings bent on destroying humanity. Created by Vector Industries, she comes equipped with a variety of weapons and a generator which activates the Hilbert Effect used to draw the Gnosis out of their dimensional flux and into normal space.

Vector Industries decides to cancel the KOS-MOS Project in favor of the T-Weapon Program (the project resposible for creating T-elos). After being used in a live-fire exhibition, KOS-MOS was dumped in a trash compactor but she was re-activated by Shion. She continued travelling with them until they encountered T-elos at Rennes-la-Chateau. KOS-MOS was overwhelmed and defeated, and after extensive analysis, she was unable to be repaired. This changes however, when Shion obtains the original designs of KOS-MOS from a past Kevin Winnicot (though still unknown to her) while going undercover as a U-TIC employee. With the help of Erde Kaiser's technology, KOS-MOS was rebuilt into her current Ver. 4 form.

She had gained more power than her previous forms, but it was later revealed that KOS-MOS was actually supposed to be a prototype for T-elos used for the resurrection of Mary Magdalene. On Michtam, the group makes their way to Zarathustra when encouter T-elos again. The battle seemed evenly matched due to KOS-MOS' upgrade, but then she deflect's T-elos' shots with one hand, which she couldn't do in thier last fight. She then shatters the globe on T-elos' head after stunning her with her own Phase Transfer Cannon, shutting her down.

Wilhelm tries to convince KOS-MOS to activate Zarathustra, but instead destroys the key and defeats it along with Shion and the others. As Zarathustra goes out of control, KOS-MOS says her final goodbyes to her true love Shion and stays behind to protect Chaos and Nephilim while they summon the spirits of the Gnosis in order to return to the "Land of Origin" also known as Earth. While she manages to rout most of the incoming Gnosis, a Cathedral-Type Gnosis appears from behind the pair. To protect them she sacrifices herself by using her Phase Transfer Cannon and creates an enormous explosion.

### Personality

KOS-MOS is equipped with a "Simulated Personality OS", or artificial intelligence (AI), to aid in communication. Though her speech conveys her role as a robot in service to humans, the basic tenet to which she adheres is based on logic, probability, and completion of her mission above all else in all situations. She also unconditionally protects Shion. The algorithms she is programmed with do not support the comprehension of illogical human thought.

KOS-MOS also possesses a wireless U.M.N. connection and can instantly answer any question asked - for example, if KOS-MOS is asked what the capital of the Galaxy Federation is, KOS-MOS will reply "Fifth Jerusalem". At one point, Shion is confused by Albedo being attached to Rubedo, and KOS-MOS explains how twins can share organs.

KOS-MOS's elemental data structure duplicates that of a human brain. She appears to be emotionless, but throughout the series, evidence indicates that this is not entirely true. A predetermined set of emotions has been hard-coded into her emotion module to better facilitate interactions with humans. She will emit an expression such as sadness only when that response is deemed necessary. However, if the emotion module of her program has determined that it is not currently necessary, she will not emit an expression.

KOS-MOS has AAA class encryption. It is a designation given to areas requiring the highest levels of restricted access. As one of the highest classified components of Project Zohar, KOS-MOS falls under this designation. KOS-MOS' importance to this project is evident in Jr.'s comment that the only other entities with that class of restriction would be the "Federation government's motherframe, or the U.M.N. operating system."

A human-like alternate persona appears occasionally in the form of a blue-eyed KOS-MOS. Blue-eyed KOS-MOS appears to be more powerful than red-eyed KOS-MOS and talks in a more human-sounding voice. This form of KOS-MOS only seems to appear at times when Shion is in extreme danger and plays the role of Shion's guardian. Shion has not directly seen KOS-MOS in her blue-eyed form and is oblivious to this second persona's existence until Episode III.

## Abilities

KOS-MOS has significant powers believed to be superior to all other party members, with the possible exception of Jr.'s Red Dragon Mode. In addition to superhuman strength and speed, her body is formed from some sort of highly advanced nanomachines that allows her to morph parts of her body (specifically her arms) into various energy projectile and melee weapons. This body is also able to self-repair and is very durable though not indestructible, and she is also protected by a force-shield.

She also possesses the ability to summon specialized weapons such as the F-G-SHOT gatling guns and her famous F-SCYTHE and equipment without the use of the U.M.N., due to the usage of a Transfer System.

She has a long-range sensory array, the D.S.S.S. (Double Slot Sensory System, read as "D-triple-S") and CPU that either rivals or exceeds even those possessed by 100-Series Observational Realian. The D.S.S.S. detects Gnosis in the imaginary realm.

She also possesses the Hilbert Effect, which is used to draw the Gnosis into our plane of reality, allowing us to come into contact with them, instead of them being able to interact with our plane's matter at will. Using Hilbert waves is proven to be one of the few ways to even attempt to attack a Gnosis. Once the Hilbert Effect has dissipated, any Gnosis previously affected will return to their state of invulnerability. KOS-MOS' power is easily thousands of times greater than that achieved by even the largest spaceships. Ultra Wide-Range Hilbert is the deployment of the Hilbert Effect over an extremely large area. Ordinarily, the range of KOS-MOS' Hilbert Effect is set to cover a radius of about 300,000km. However, when Shion witnessed the impending massive swarm of Gnosis, she decided to enlarge the effective range to a radius of several hundred AU (astronomical units).

KOS-MOS has a Secondary Weapon System which is KOS-MOS's main combat equipment; this refers to her current armament, frame material, and substitute armor materials. The Secondary Weapons System made experimental use of a PT cartridge-type phase transfer cannon; the limited unit size, however, meant that the places and situations in which it could be used were restricted. For this reason, the Tertiary Weapons System, with a phase transfer unit installed as standard equipment, was produced on Second Miltia.

KOS-MOS has one last optional weapon system called the Tertiary Weapon System, which is seen periodically throughout the series. It was designed by Kevin while he was still alive and built at Vector Second R&D Division on Second Miltia. They consist of a set of energy wings, a pair of energy cannons and other attachments meant to be fitted onto her. The wings and cannons are part of a Phase Transfer Cannon. Because the phase transfer cannon units are made to be as compact as possible, the recoil when the are fired is very high; the Version 2 KOS-MOS Combat Frame is required to fire these weapons. The PT cartridge-type phase transfer cannon used by KOS-MOS when the Song of Nephilim appeared had been created as a testbed for these cannons. When the cannons are fired, a cooling field in the shape of glowing wings is created behind the unit. While wearing this gear she is shown in a premonition flying through space at sub-light speed and then confronting U-DO above an unknown planet (presumably Miltia) and the exchange that follows destroys several planets. The "Third Armament" as it's also known makes a real-time appearance in Episode II on the Omega System. KOS-MOS uses this equipment to protect Shion and the party from a U.M.N. Phase Transfer Cannon fired by Proto Omega.

KOS-MOS possesses several black box components left behind by Kevin since the current KOS-MOS is essentially the archetype resurrected. There are still many 'black boxes" to be revealed but two include her potent "X-BUSTER" a weapon that fires powerful energy beams from her abdomen as well as absorb Gnosis, and components that her give her some kind of self-awareness. KOS-MOS also has some form of energy manipulation tied to the Zohar.

Finally, KOS-MOS also has the ability to dance.

### Skills

#### Class Skills

* Independent Action (B Rank): KOS-MOS is able to act without the will of her master for a separate amount of time.

* Magic Resistance (B Rank): KOS-MOS has durability in order to endure certain amount of attacks.

* Riding (D Rank): This due to her riding her space bike, the Mobile Dinah Interface.

#### Personal Skills

* A.G.W.S. (C Rank): KOS-MOS can summon and enter a small mech at will as long as it is already bound to an alternative power source; with this power source readily available, it can function indefinitely. Although powerful in their own right, they are downscaled mechs and therefore lack the power of a larger mech. She can choose from a number of small mechs and upgrade them as needed. If the mech is destroyed while she is inside, KOS-MOS will become trapped until the machine is repaired.

* Battle Continuation (A Rank): KOS-MOS is able to continue the battle with her opponent, even if she were to sustain some damage to her body.

* Divinity (E Rank): KOS-MOS contains the spirit of Mary Magdalene, whose power of Animus combined with her association with the Messiah gives her a small degree of divinity.

* Eye of the Mind (Fake) (A Rank): KOS-MOS is equipped with a long-range sensory system.

* Librarian of Stored Knowledge (B Rank): KOS-MOS’ databanks allow her to recall most events.

* Mental Pollution (D Rank): Being an android, KOS-MOS has limited understanding of human concepts\*. Rank lowered since her past memories as Mary are giving her a better grip of emotions.

* Shapeshift (D Rank): While KOS-MOS cannot change her primary shape, she can alter parts of her body to create new weapon systems.

### Noble Phantasm

#### **Tertiary Weapons System**

KOS-MOS summons a number of equipment that attach to her body, including wings and cannons. These attachments boost her power. When the wings and cannons are combined, they form a Phrase Transfer Cannon, which transfers mass into energy with destructive potential. If used with enough force, it has the potential to destroy a star.

#### **Hilbert Effect**

KOS-MOS generates a large scale Hilbert Effect, which was designed to combat the Gnosis. The energy field forces all incorporeal occupants into physical form, making them more vulnerable to attack. However, this does not lower their power normally. Once the Noble Phantasm ends, all warped individuals revert to their incorporeal forms. In addition, the Hilber Effect jams all sensor technology unless specifically adapted for the effect. Also, it prevents the usage of Prana-powered weapons unless calibrated ahead of time. Needless to say, KOS-MOS is already equipped to resist the effects.

#### **X-BUSTER**

Her Anti-Army Noble Phantasm. KOS-MOS releases a stream of blue beams of light upon the enemy servant. This was used to eliminate an entire fleet of spaceships.

#### **D-TENERITAS**

KOS-MOS stuns the enemy before entrapping the enemy in a sphere using the Phase transfer Cannon. The sphere then implodes before detonating.
