Avenger (Fate/Crossover - Asimov)

*"A battle between the superhuman and the powerless — or should I say, Adept against Mino? That's how things are these days, is it not? Let's put it all on the line! This is our war by proxy!"* - Asimov.

**Avenger** (アヴェンジャー, *Avenja*) is the servant of ??? in the ??? Holy Grail War.

## Profile

### Identity

Avenger's true identity is **Takefutsu** (タケフツ)**,** also known as **Asimov**. Said to be the vagrant child of two illegal immigrants in Japan, he was captured by Sumeragi’s Hunters and was discovered to be a "match"--a normal human with latent Adept potential--and potentially compatible with the lightning Septima, the Azure Striker, at that. He was then used as a test subject in Sumeragi's Project Gunvolt energy research, and received a transplant from the deceased original Azure Striker wielder, making him into an artificial Adept.

While he was being experimented on, an accident occurred and Asimov's power went out of control, completely destroying the lab he was held in and killing all personnel. While Sumeragi concluded that "Takefutsu" had been unable to restrain his own thunder and died too, Asimov survived and escaped amidst the confusion.

Changing his name from "Takefutsu" to "Asimov", he managed to escape overseas and from then on devoted his efforts to establishing the anti-Sumeragi international armed organization dedicated to Adept freedom and liberation, QUILL, eventually doing so with several Adept comrades.

### Appearance

Asimov is a young adult with shoulder-length gray-blue hair and a pair of blue visor-like glasses that serve as limiters. His eyes are purple, and lack highlights.

He typically wears a gray armored long coat with black highlights and arm armor. He also sports white trousers with black highlights over his inner thighs and groin, and black boots with glowing blue highlights.

### Personality

Asimov generally keeps an aloof, professional demeanor about him in the midst of combat. He takes his duties, and those of others, extremely seriously, and has very little patience when it comes to those who disobey him. This attitude tends to leave him in serious conflict with his Master due to varying opinions.

However, Asimov does have a lighter side to him outside of battle. He can be surprisingly eccentric at times, showing great interest in Japanese culture and even singing karaoke. Despite his usual stoic behavior, he was extremely close to his old teammates, stressing the importance of a close team, and had no qualms going out with them for a good time.

## Abilities

Asimov is an exceptionally powerful Adept who wields the **Azure Striker** Septima, which grants him the power to manipulate lightning and is said to be one of the most powerful of Septima. However, his Septima is always running wild, requiring him to wear specially designed sunglasses to restrain it.

Apart from his Septima, Asimov is a skilled marksman and firearms user, capable of picking off targets with his E.A.T.R. rifle from great distances. He also shows great mastery of the Border and can use his Septima's ability to create a electromagnetic field to guide the path of his Greed Snatcher bullets so they can home in on enemies. However, this puts a strain on the gun and may cause it to stop working if overused.

## Notable Skills and Techniques

* **Magic Resistance** (B Rank):
* **Self-Replenishment (Mana)** (C+ Rank): Although his powers may use up mana, he possesses a natural ability for slowly regaining energy in time for the next battle.
* **Oblivion Correction** (A Rank): He will never forget nor forgive the injustices done upon him or his fellow Adepts. Until the end of his days, he will push for the extermination of all non-Adepts.
* **Presence Detection** (C Rank): It is said Adepts are capable of detecting the Septimal waves of other Adepts. Upon his manifestation as a Heroic Spirit, this ability was transformed to allow him sense the presences of other Servants within a certain radius.
* **Battle Continuation** (A Rank): Until his body finally gives out, he will never stop fighting until he achieves his ideal. This was the end result of the insanity brought forth by his traumatic past.
* **Charisma** (B Rank): His natural charisma, befitting one of the founding members of QUILL, has swayed many non-Adepts to his freedom-fighting cause. Even as a Servant, he retains this magnetic charm.
* **Military Tactics** (A+ Rank): As the leader of QUILL's Team Sheeps, he has led several covert operations against Sumeragi. This natural talent for covert and military warfare against a greater power remains intact even now.
* **Prevasion** (EX Rank): A natural evolution of Protection from Arrows granted to him by his Septima. This passive ability allows him to completely phase through projectiles and attacks for brief periods of time but actively consumes mana every time it is used until it can no longer be sustained.

### Noble Phantasm

#### **Devourer of Sin: Greed Snatcher**

A special shot type for Asimov's additional gun, the Border, with the property of controlling others' Septimas. Upon his ascension as a Heroic Spirit, it's properties were altered to allow it to directly interfere with a Servant's Spiritual Core upon a successful hit and severely hinder the opponent to the point of preventing them from using their Noble Phantasm. As the Border was stolen from it's original owner, this Noble Phantasm lacks it's full power and it's effects are only temporary.

#### **Septimal Surge**

As soon as Asimov removes his sunglasses, this Noble Phantasm passively activates allowing to unleash the full might of the Azure Striker. In this enhanced state, his combat parameters and general power receive a noticeable increase at the risk of his powers potentially losing stability and burning him out the longer he uses them.

#### **Azure Thunderclap: Voltaic Chains**

* Voltaic Chains
* Voltaic Buster
1/2
A Noble Phantasm that embodies the essence of the Azure Striker. When active, large chains criss-cross the battlefield before electrifying themselves, dealing damage to those who touch them. If the chains ensnare the opponent, Asimov immediately zeros in on his target and follows up his attack with **Voltaic Buster**. This attack involves Asimov grabbing the opponent and flying into the air before slamming them through his chains and into the ground.

#### **Final Judgment of the Mad God: Voltaic Chain Meteor**

An evolved version of Voltaic Chains and Asimov's ultimate Noble Phantasm. Due to having been summoned as an Avenger, he is unable to access this particular ability and it remains sealed.

## Trivia

* His Archer counterpart is nearly identical to his Avenger self with a major difference. Due to that version being based on "Asimov the freedom fighter" instead of "Asimov the Adept supremacist", he lacks access to the Border and most of his Noble Phantasms with the exception of Septimal Surge. When used, it will automatically transform him into his Avenger self.
