I strive for something beyond the strongest, that challenging me would be the most ridiculous thought ever, that fighting me would be a sin!
~ Accelerator

I have no interest in being a villain, and I don’t think that I can become a good person. I’m at a halfway point where I’m not even sure which path I should walk down… but I guess even there, I can still interfere in someone’s life and help bring things to a positive conclusion…
~ Accelerator

It's ridiculous that a villain who was no better than a piece of shit like me was guarding her! No matter how you think about it something must have been wrong! How could I possibly be a hero! No matter what, I can only choose the blood-stained path! Why do I have to do all these things! If a hero like you had shown up earlier, then something like this mix-up of position wouldn’t have happened! That brat would not had to have suffered as much this way!

The Accelerator is the name used to refer to the 1st-ranked Level 5, the strongest esper currently residing in Academy City.

First appearing chronologically in To Aru Majutsu no Index as an antagonist, he later becomes the second protagonist of the series and primary male protagonist of the Science Side after being defeated by Kamijou Touma. His journey to a more "heroic" role in the story progresses after meeting and saving Last Order, and is forced into an ironic twist of fate where his life now depends on the Sisters, clones he previously killed by the thousands. He is also a major antagonistic character in To Aru Kagaku no Railgun and is the protagonist of To Aru Kagaku no Accelerator.

In his role as a protagonist, he is forced to deal with the cruel Dark Side of Academy City, the secret conspiracies surrounding it, the guilt he carries from the Level 6 Shift experiment and his inner conflict about his status as a villain/hero. As the most powerful esper of Academy City, his existence and powers are tied to the plans of Aleister Crowley, the founder of Academy City, alongside Kamijou Touma.

Stamina: High, can continue to fight after severe injuries, managed to use his powers while unconscious after getting shot in the head to save his life and Yoshikawa's, and also managed to continue attacking Aiwass after being nearly sliced in two by its wings. However, the battery of his choker that lets him use his esper power is limited to 15/30 minutes. This time limit does not apply in his other angelic forms.

Intelligence: Extraordinary Genius. His intellect exceeds a hundred supercomputers. Accelerator's esper ability has been shown to require complex calculations to function, with him being skilled enough in this field to come up with a new application on the fly during his battle against Touma. He also appears to have a very good memory, as he memorized the codes for Last Order's default mind state and was able to remotely return her to that condition, thus erasing the virus planted into her by Amai Ao. Later, he also starts to display well-thought out strategies in battle, like when he was able to take out the Hound Dogs using guns, which he utilized for the first time against them, along with exploiting his immediate environment and psychological tactics to his advantage, without using his esper ability. Even with less than half of his calculation ability, it is great enough to allow Accelerator to calculate and analyze all the 25,000 different kinds of energy of Kakine Teitoku's Dark Matter was emitting at once and updating his ability in order to reflect them, while fighting on par with Kakine and protecting the bystanders. Unknown with Platinum wings. Has likely tremendous amount of knowledge about the occult to an exponential degree via the third tree. Has access to all of Academy City's resources and databases with the authority as the Board Chairman.

Weaknesses: Overconfident and sadistic; tends to stand around and willingly allow attacks to reach him due to having never suffered defeat before in his life | The electrode which lets him use his powers only has 15/30 minutes of battery, and utilizing magic spells can result in grievous injuries if not properly protected against with vector control | Rational thought processes can potentially be overwritten by uncontrollable blood-lust | None notable | None notable

Notable Attacks/Techniques:

Accelerator (一方通行 (アクセラレータ) Ippō Tsūkō (Akuserarēta), lit. "One-Way Road"): The unique esper ability of the strongest Level 5, also used by Accelerator as his name since he has forgotten his original name. Known as Vector Transformation (ベクトル変換 Bekutoru Henkan), Vector Change or Vector Conversion, it creates a thin field of AIM around him, which allows him to modify the vector values of anything he touches. It allows him to manipulate all kinds of physical vectors, from those related to kinetic energy to ones related to heat and electricity. It is initially limited to attacks that work using the regular physical laws, but through the use of Accelerator's massive intellect and calculating prowess, he has been able to incorporate vectors that were unknown to him and worked under different laws like Kakine's Dark Matter's, magic's or Telesma's into his equations. The nature of a Personal Reality allows an esper to enforce their own internal system of laws onto the world, and the process of doing so entails observing and controlling the microscopic possibilities within the quantum level.

  • Redirection/Reflection (反射 Hansha): Accelerator's passive application of his esper ability. He automatically inverts the direction of any incoming harmful vectors, even if he is unaware of their presence. He must consciously allow things like gravity, sound and light to affect him, but he can shut them off too if he wants it. Since it is bound to his calculation speed, attacks that are significantly faster than light can likely pass through without being effected. Because his passive reflection changes just the direction of the attacks, but not their magnitude, one can argue that his reflection is not dependent on the magnitude of the attacks. However, to avoid NLF, it is simply listed as High Complex Multiversal instead for performing feats on this level.
    • Coordinate Attack Immunity: As well as stopping conventional attacks, Accelerator has demonstrated feats of preventing the activation of coordinate-based attacks inside of him along with redirecting the 11-dimensional vectors of teleportation, causing a strange undescribed phenomenon upon doing so.
    • Internal Spell Immunity: In addition, by incorporating his newfound knowledge regarding Magic, Accelerator has developed an immunity to spells that specifically target his inner body, as showcased throughout his battles against Elizard's All-Dimensions Severing spell and Nephthys's water-based moisture-draining technique.
    • Empathy/Madness Immunity: Perhaps as a side-effect of his heightened magical awareness, Nephthys's Tears of Transmission were incapable of affecting Accelerator's psychological state, and Qliphah's mental corruption from her dress did nothing when he looked directly at them. Note that this is limited to transmission-based techniques, such as those requiring visual contact.
  • Vector Control (ベクトル制御 Bekutoru Seigyo, lit. "Vector Control"): The active application of Accelerator's esper ability. By touching an object, he can freely manipulate its existing vectors or even apply some new ones.
    • Increased Strength: One of the most basic uses of his power, Accelerator can exponentially increase the strength of his actions by manipulating his own vectors. He can launch humans or powered suits flying with what should be a light touch, which is considered holding back as he's capable of simply causing a human to explode with a light tap. He can similarly collapse a large section of a wall just by tapping his hand on it. The magnitude of his strikes can potentially be augmented up to High Complex Multiversal, but is entirely dependent on the opponent's own durability, via reflecting and multiplying the rebounding/reactionary forces encountered upon contact.
    • Increased Speed: By altering the vectors for the motion of his feet Accelerator can cover long stretches of ground in one step at high speeds, with the movement compared to a bullet since he's using his powers to essentially shoot himself forwards in a straight line.
    • Air Manipulation: He can manipulate the vectors of the air surrounding him to affect the air in a large area, being able to affect the entirety of Academy City before suffering his brain injury. He can use this high-velocity wind in numerous ways: he can create air blasts/shockwaves, spear-like gusts of 120m/s wind, tornadoes, air bindings to restrain/crush humans, compressed air spheres that he can slam into the enemy as an attack, walls of wind that can trap an enemy and even a spherical wind barrier as protection. However, manipulating air through vectors requires extremely difficult calculations, so these can be disturbed by an opponent in specific ways to disturb those calculations and counter his attempts to use wind.
      • Plasma Storm: Accelerator can further compress the wind at high speeds in a single point. Compressing the air like this creates tremendous amounts of heat, forcibly causing the atoms in the nearby air to split into cations and electrons which then turn into plasma, culminating in a sphere of light with a radius of 20 meters and a temperature of 10000º. This technique has a long charge time, so Accelerator normally doesn't use it.
      • Flight: Accelerator can create 4 high-powered tornadoes attached to his back in order to fly.
    • Gravity Reversal: Accelerator willingly allows gravity to affect him in order to anchor himself onto the planet and can likely modify that at will, allowing for very limited levitation.
    • Dust Explosions: If there is enough dust in the air, Accelerator can trigger a dust explosion.
    • Vector Shooting: By touching an object he can immediately change its movements vectors to launch it at high speeds as a projectile. He has used this to do things like launch metal construction pillars, throw metal containers or cars, kick pebbles at high speeds and turn regular falling leaves into a storm of razor sharp bullets.
    • Vector Slice: Accelerator gathers weight or other vectors into a razor-thin blade that he can send towards the enemy as an invisible and silent slicing attack. For example, he once sliced the chains binding a prisoner just by moving his fingers, and when terrorists were trying to fight him the narrations describes their bodies being harmed as soon as they acted hostile without mentioning Accelerator ever needing to touch them: "Taking hostages didn't work. As soon as they tried to reach for the kids, their wrists were twisted in an unnatural manner. Dynamite didn't work. As soon as they tried to push the button for it to explode, their fingers were blown away along with the button".
    • Vector Analysis: Accelerator can sense and perceive the environment entirely through vectors, obtaining information such as frequency, speed, magnitude, size, structure, etc. One common application of this power is for him to predict the enemy's movements using the analyzed information.
    • Brain Hacking: According to Accelerator, by redirecting the electrical signals of the human body he can take 'control' over them and rewrite the memories and personality of the people as was shown in volume 5 with Last Order, though unlike proper mental type espers who can interpret those signals, he needs a previous reference to be able to achieve concrete effects. This technique requires immense amounts of calculation power. Since those completely strained the brain of Accelerator prior to suffering brain injury, it's unlikely he can replicate the same feat after losing half his calculation power.
    • Body Manipulation: By touching a person, Accelerator can read all the vectors in their body (which has the side effect of doubling as a crude medical checkup) and take total control of their body. He can use this to reverse their bloodflow and/or biolectricity, which would instantly kill them. He can similarly instantly rip off all the skin of a human by touching. Accelerator can also similarly manipulate his own bloodflow to survive what otherwise would be lethal injuries, like when he used his vector manipulation to keep his blood circulating after Aiwass had nearly cut him in half with its wings, even circulating his blood through air. He can likely do the same with his own biolectricity.
    • Earth Manipulation: Manipulating the vectors on his feet, he can cause an explosion made of earth and launch rocks to attack his opponents with a stomp. If he wants to, he can launch stones faster than a railgun. When doing this the stones vanish after a few milimiters, but the intense pressure waves continue. He can also create gigantic fissures, earth tsunamis and several earth spears to pierce his opponents.
    • Planetary Vectors: If needed, Accelerator can obtain massive amounts of energy for his techniques by syphoning it off the planet's rotation, revolution and all other forces. As seen with his attack on the Windowless Building, Accelerator can use up so much of the planet's rotational energy that it slows down the earth's rotation by about 5 minutes. Theoretically this attack should allow him to extinguish all life on the planet.
  • Angelic Transformation: After developing/updating his powers and Personal Reality, Accelerator has gained the ability to manifest wings that have been compared to an angel's wings. The composition of the wings is unknown, Index Librorum Prohibitorum described them as resembling a field of Telesma, but using a different substance; and Kakine Teitoku stated they were Dark Matter. Accelerator's wings appear to have some unknown esoteric effects, as Beetle 05, who should have the same level and speed of regeneration as the old Kakine, had some issue reforming his body after it was crushed by Rensa using Accelerator's black wings. In addition to that, upon awakening to his wings Accelerator displayed the power to manipulate vectors from a distance.
    • "ihbfKILLwq"

      Dark Wings: Accelerator manifests dozens of dark wings that seem more like jets than wings as they spray a jet black ink-like substance that seems to swallow light. Also, Accelerator's voice starts to produce weird noises in this state as he tries to speak angelic language, much like Gabriel or Aiwass do at times. The wings are incredibly sharp, easily slicing through multiple buildings just by its regular movements when they first appear. The shape and size of the wings can be controlled by Accelerator at will, who can even split a wing into a rain of dozens of sharp stakes, each one of them being 100 meters long. While using the wings Accelerator's body is much more durable, easily taking a grenade exploding centimeters away from his head without suffering a scratch. He is also capable of utilizing an 'unexplainable invisible power', capable of launching Amata Kihara into the sky at dozens of times at the speed of sound, turning him into plasma; as well as crushing Kakine Teitoku deep into the ground and tearing off his right hand with a single motion of his hand. Going by his and Rensa's uses of these wings, they seem to appear when Accelerator's emotions run out of control and/or he's cornered in a fight.
    • "I get it... this is what it means to fight to protect."

      White Wings: An apparently more powerful version of his dark wings, Accelerator first used these wings during the climax of World War III. While not a lot is known about these wings, his defenses rise considerably with them; as he was able to tank a attack that could destroy all of Eurasia without his vector shield. Unlike the previous wings, these ones seem to be created by Accel's honest desire to protect something. Noticeably, the first time he used these wings he also manifested an angelic white halo, but neither he or Rensa have managed to replicate this halo in later uses of the white wings. By flapping the wings Accelerator can convert some 'unknown energy' into lift and fly without emitting any force down to the earth.
    • Platinum wings: A more powerful version of his white wings, Accelerator first used these wings during the fight against Coronzon. The wings are achieved thanks to the connection to the metaphysical Clonoth, a tree very similar to the Sephiroth that is more conceptual than physical, such a connection is achieved trough the linking of Qliphah Puzzle 545, himself and the Will of the Misaka Network. The wings are similar to those of Aiwass, and are supposed to be a combination of both magic and scientific knowledge, not much has been shown until now, but we can safely assume they at least have the same property of the white wings, as well as giving him access to soul/law manipulation, the capability of performing Holistic phenomenon, and an instinctive understating of magical and conceptual vectors for now. The same 'unknown energy' used in his previous winged forms can now be converted into spears-like shapes that are able to nullify magical phenomenon through its inflicted damage. Noteworthy that even in this form casting a spell process still kicks in the recoil damage common for espers, but the increased durability that comes with it generally makes up for that drawback instead.
  • Magic: Accelerator has demonstrated a basic understanding of magic. In volume 22, he used his vector ability to interpret the song used by Index to save Last Order and repeated the breathing method, casting the spell. As this was a pure magic spell, he suffered serious harm but saved Last Order. After an explanation on the theory of magic provided by Leivinia Birdway, Accelerator displays his extreme delicate control over magic to having a side effect of using magic as unnaturally sweating rather than rupture of blood vessels and organ damage. An example of this is even when he has only a rough idea what Feng Shui was, he is able to use a limited magic detection and then combine it with his knowledge of group psychology to increase its accuracy. His knowledge on magic has since deepened even further. He demonstrated manipulating the vectors of magic in order to eliminate Qliphah Puzzle 545's contract with Coronzon, without harming her. This act was so difficult, that not even Aleister and Mather's had considered doing it this way and may or may not would have been able to. However, when it comes to the proper use of magic Accelerator is still an amateur. After crossing the Abyss and embedding the Clonoth into reality, Accelerator has gained a much better understanding of magic. Qliphah Puzzle 545 has stated that Accelerator had now fully analyzed the world of magic and can better use magic himself, although to what extent is still currently unknown.
    • Clonoth: The previously unamed Tree which Accelerator rewrote and implanted into the Phase. So far he has demonstrated that once a connection is established to this tree through Qliphah (likely instantaneous) it increases his calculation powers and upgrades his reflection capabilities. Giving him now the ability to manipulate unknown energy in the form of invisible vortex-like spears to null Magic and an upgraded field that carries Anti-Magic properties.
  • Marksmanship: Accelerator has been shown to be extremely proficient with firearms (in SS1). Even with only his weaker left hand, he was able to finish off a round of practice in 70 seconds. He has commented that reloading a pistol in two seconds with one hand is too slow for him, even though he was just testing the guns. As proven during his fight with Killer Point, Accelerator can make impossible shots by shooting himself while he has his vector shield active, allowing him to take control of the bullet's vectors and gain absolute control over its path in the air, which he used to shoot Killer Point after he had taken an innocent hostage.
