Kakine Teitoku


 * ''This article deals with the Original Kakine Teitoku. For the current Kakine Teitoku, please go to the Kakine Teitoku (Beetle 05) article.

Kakine Teitoku (垣根 帝督) is the second ranked Level 5 of Academy City. First introduced in the 15th light novel volume. As the leader of the SCHOOL, one of the many underground factions in Academy City, he and his faction came against Accelerator and GROUP, and was utterly ruined by the former after their confrontation. Afterwards, he was used by Academy City to produce technology for them, but his will lingered on. In the 5th Shinyaku Toaru Majutsu no Index Light Novel Volume'', he revives himself through Dark Matter, in order to handle the situation with Fräulein Kreutune as well as to deal vengeance upon Accelerator.

Etymology
Teitoku's full name can be translated as "Emperor of the Front Fence," which suits his personality.

Appearance
He has shoulder-length dirty blond hair and often wears a cocky smile, though in his interaction with Uiharu Kazari, it is shown that he can fake warmth and kindness. Kazari also notes that he radiates an almost vulgar sense of style. He wears a dark maroon colored suit with a white collared shirt, both unbuttoned, revealing a red v-neck under them.

Revival
After his revival in the second series he still wears the same clothes as before. His body however has become ghostly white, an effect of his power being regenerated from his Dark Matter. His eyes have changed becoming more sinister gaining yellow irises and dark sclera. A deep darkness could be seen when he opens his mouth.

Personality
He is a rival with Mugino Shizuri, ITEM's leader and the #4 Level 5 esper. He strives to become the strongest, even if it means that he needs to kill off Accelerator. He's also a ruthless, cocky, and cold hearted individual, though at times he may show mercy. When attempting to find Last Order to draw out Accelerator, he attacks and tortures Kazari and was on the verge of killing her when she refused to give him Last Order's location ; but when attempting to eliminate Takitsubo Rikou, he decided to let her go as she was already on the verge of self-destruction from over-use of her ability. He prefers not to get innocent people involved in his battles, though if they do get involved, he will not go out of his way to protect them. However, he shows no mercy to his enemies or anyone who opposes him and will crush them without hesitation.

Hamazura Shiage notes that though Teitoku and the rest of SCHOOL are horrible people, yet the fact that they still have the humanity to let those weaker than them live makes them far better than Mugino, who kills her own comrades simply because she is annoyed by something. In his fight with Accelerator, it was noted Teitoku probably also went through tragedies like the kind Accelerator went through which twisted his personality. He is extremely envious of Accelerator because of his right to communicate directly with Aleister and seeks to defeat him and become the #1 Level 5 so that he may have that right. Teitoku has the tendency to spout sarcastic remarks inside and outside the battlefield, things like praising his enemy while he actually is talking down to them, or stating “That hurt” when a direct attack failed to damage him in anyway.

Background
It is implied by both Accelerator's thoughts, and Teitoku's own words that tragedy has struck him in the past, like Accelerator, that made him walk the path of darkness. Teitoku compares Accelerator to him after attacking Yomikawa Aiho as the same as he is, unable to protect anybody.

Teitoku was apparently aware of Aleister's plans, and was distasteful of him being the Spare Plan. He later forms SCHOOL, with the intention of forcing Aleister to negotiate with him.

Pre-revival
Before his revival and release from the facility where he was kept, he was somehow aware of what was happening to him, like being used to produce Dark Matter for military use. Moreover, he was quite aware of Accelerator, and did research on him, especially with regards to the wings Accelerator possessed. When he was still kept in the facility, due to the usage of his body to produce Dark Matter, he was able to create what he had lacked, forming a new body that had been destroyed. In essence, he was learning as he was producing Dark Matter for the City.

When he was called out for his assistance by Kihara Yuiitsu, he had apparently left behind his real flesh and blood organs behind somewhere, and created a body completely made of Dark Matter.

Daihasei Festival Arc (Railgun)

 * Main article:Daihasei Festival Arc (Railgun)

Before the beginning of the Daihaseisai, Teitoku is inquired about participating in a demonstration of Level 5s by the Daihaseisai committee through SCHOOL's usual agent. He refuses, but the agent insists, earning a lashing from Teitoku. The agent then suggests that Teitoku's power, more specifically, his white wings, would have appeal among kids. Teitoku's pride was severly hurt as shown that he went berserk afterwards and wrecked SCHOOL's hideout. The Boy with goggles and Girl in dress are amused, but are quickly silenced by Teitoku's furious glare.

Battle Royale Arc

 * Main article:Battle Royale Arc

Kakine Teitoku was the "Spare Plan" for Aleister Crowley's plan in the event that Accelerator would not meet Crowley's expectations.

The first time when he is mentioned is when Mugino Shizuri and ITEM assault the District 5 Virus Isolation Center. ITEM encounters SCHOOL there, and are presumably able to kill Boy with goggles before being forced to retreat, leaving behind both Frenda and Kinuhata Saiai. While escaping, Shizuri reveals that Teitoku was with SCHOOL at the destination and she was defeated.

The first time Kakine Teitoku is seen in person, it is revealed that he has managed to obtain the Pincet Glove or Tweezers. He explains that he plans to use the glove in some way to get close to Aleister. He is then ambushed by "The Professor", the leader of MEMBER who uses his "Mimosa" machine to attack Teitoku. Believing that he has won, The Professor begins to gloat about his victory to Baba Yoshio. However, Teitoku reveals that he was in fact still alive, having been able to detect the Mimosa using the Pincet Glove, and defending from the attack - presumably with some application of his ability- proceeded to kill The Professor.

Later, he attacked ITEM in an attempt to eliminate Takitsubo Rikou. However, Saiai manages to help both Takitsubo and Hamazura Shiage escape while Mugino held Teitoku back. However, Teitoku easily defeated both Mugino and Kinuhata (though he leaves both of them alive) before intercepting Takitsubo. Takitsubo opts to save Hamazura and stays to fight Teitoku on her own, but Hamazura returned to help her out afterwards. Takitsubo attempted to defeat Teitoku by forcibly taking control of his AIM field and turning it against him, but fails and was defeated. As Rikou was already on the verge of death due to her over-use of Body Crystal, and because he does not view Hamazura as a threat in the first place, Teitoku leaves them both alive, informing Hamazura that if Takitsubo uses Body Crystal again, she will most probably be destroyed.

Later, Teitoku talks with the Girl in dress, the only other surviving member of SCHOOL. First, the two of them discuss how ITEM has fallen apart, and he manages to infer that it was Hamazura who defeated Mugino and finds the achievement impressive. They then discuss UNDER_LINE, the network of 10 million nanomachines that Aleister Crowley uses to monitor Academy City. Teitoku reveals that while he has managed to use the Pincet Glove to analyze Underline, he still does not have enough leverage to bargain with Aleister. As such, he has decided to kill Accelerator so that he can negotiate with Aleister regarding becoming the core of his plans. The Girl in the Dress refuses to help because she is scared that her ability will be ineffective against Accelerator, but states that if Teitoku succeeds, he should contact her.

In order to reach Accelerator, Teitoku decided to first take Last Order hostage. To do this he captured and tortured Uiharu Kazari for information on Last Order's whereabouts. He was about to kill Kazari when Accelerator launched a surprise attack on him.

During their first clash, Accelerator easily blasted Teitoku into a nearby building. However, Teitoku walked out of the building, revealing that he is completely unharmed and that he has fashioned for himself Dark Matter wings. He was able to corner Accelerator, revealing that his Dark Matter is able to bypass Accelerator's Reflect by exploiting a logic fault in Accelerator's barrier. However, Accelerator manages to update his AIM field and add Dark Matter to the list of things he can control. Accelerator then proceeds to hold an advantage by using Dark Matter against Teitoku.

Accelerator defeats Teitoku and was about to kill him, but was stopped by Yomikawa Aiho. However, Teitoku was angered that Accelerator hesitated to kill him and attacked Yomikawa. This drives Accelerator over the edge, and he also "Awakens". After observing Accelerator's Awakening, Teitoku realizes the true nature of his own ability and completely awakens and can now master his Dark Matter, believing that he was now capable of defeating Accelerator. However, Accelerator easily smashed Teitoku into the ground and then proceeded to rip apart most of his body.

DRAGON Arc

 * Main article:DRAGON Arc

It is revealed Teitoku is currently being kept alive by "Dark Legacy", where his brain is preserved as a constant source of Dark Matter.

World War III

 * Main article:World War III

Although he can be considered as "mostly dead", Teitoku is still alive and being kept in Dark Legacy, apparently a life support system that Aleister has confidence in to allow Kamijou Touma to survive in, when he gives the order of in retrieving him back to Academy City, keeping it best that he is alive. However, the order dictates that if he has sided with an external organization, he is to be promptly attacked and retrieved and kept within the same life support system as used for the Kakine Teitoku.

Teitoku's Dark Matter ability is later used in the production of Academy City's new Equ.DarkMatter Powered Suits. It should be noted that they primarily use White wings made of Dark Matter to attack, and that the wings are described as organic.

Baggage City Arc

 * Main article:Baggage City Arc

Because of Kihara Byouri's use of him during the Natural Selector via her Equ.DarkMatter implant technology, communicating directly with his remains in Academy City and using his powers, Kakine Teitoku has gained the ability to create human tissue with Dark Matter, a fact Kihara Yuiitsu says is worth the lost of the three Kiharas sent to battle GREMLIN. Interestingly, when Byouri fought Kihara Kagun, Kagun inferred that Teitoku's personality was trying to overtake Byouri's via the implant link. Although she controlled the electric pulses that dictated the flow of Dark Matter, the Dark Matter itself retained the presence of Kakine Teitoku himself which put a strain on Byouri's spirit. If things had gone on for much longer, Byouri's spirit would have been crushed and her body left soulless.

Ichihanaran Festival Arc

 * Main article:Ichihanaran Festival Arc

Some time after being defeated by Accelerator, Kakine Teitoku apparently somehow managed to recreate his body using Dark Matter alone. Teitoku reappears when Kihara Yuiitsu, someone who has been keeping watch on him and studying his powers, enters the big concrete room where he is kept in a hidden underground laboratory in School District 3. The entire room is covered with a white substance that has the texture of a silkworm cocoon, and at the center in a spherical chrysalis is Teitoku's face. Yuiitsu explains the situation with Fräulein Kreutune and asks for his assistance. She understands that Teitoku will likely cause chaos and destruction, but since she is a Kihara, it doesn't matter to her. Thus, Yuiitsu gives him carte blanche and lets him loose in Academy City.

It is implied that Teitoku is the one behind the man who is behind the attack on Mugino Shizuri. The attack where a man dressed up as Frenda and hacked Shizuri's cybernetic eye to fool her into thinking him as a resurrected Frenda, though the assassination was unsuccessful.

The revived Teitoku first appears in public after discovering the whereabouts of Fräulein Kreutune, who is currently bothering Accelerator and company, as her body function has changed into a mode in which she needs to eat Last Order's brain. He was to quickly capture that which had been sealed in the windowless building and seal it back from whence it had come. And he was expected to do his very best to accomplish that task. However, he tells Yuiitsu that he is going to do the mission in his own way, to which Yuiitsu understands, who is interested in the destruction that will befall during Accelerator and Teitoku's battle. Intrigued by this response, Teitoku ends his call and summons several White Beetles, as well as copies of himself in the area he is in.

After one of his beetles fire a shell at Fräulein, bending her seemingly impervious body, and allowing Accelerator to kick her away. The shell caused a panic in the area, leaving only Accelerator, Last Order, and Yoshikawa Kikyou, along with Hamazura Shiage, Taikitsubo Rikou, and Fremea Seivelun. When Accelerator looked towards the direction where the shell was fired from, he sees the beetles surrounding them; Teitoku speaks using their wings' vibrations. Teitoku asks Accelerator if he remembers him, to which Accelerator answers that it's a voice he doesn't bother to remember. Teitoku says to Accelerator that he doesn't care about anyone else, even if they get hurt, as he will only focus on him, much to Accelerator's irritation, as he tries to find a way to protect or not involve others. Accelerator looks towards the roof Teitoku is located. To his surprise, several human figures accompany Teitoku, his own forms. Teitoku reveals that he is able to reproduce hsi own organs, even his own brain. With that, Teitoku tells Accelerator how he made the beetles, but calls them more like cyborgs. He then tells him that the battle will begin, taunting him, and then saying that his strength will level him up infinitely. Accelerator then shot out towards Teitoku, leaving a hole behind him and the others so they can escape.

While Teitoku fights with Accelerator, he is aware that Beetle 05 has gone out of his control, and cares not for it.

Teitoku was upon a radio tower, pondering on how Accelerator easily defeated 300 of his Dark Matter creations of himself in 15 minutes. Then a giant Dark Matter dragonfly came towards him to relate to him reconnaissance information. There, Teitoku predicts that their battle would come to a pathetic end once Accelerator's batteries run out. Teitoku then predicts one of Accelerator's actions, creating nonsense calculations. He also predicted that Accelerator would want to secure extra power, and had discovered some idiosyncrasies in the nonsense calculations that Accelerator has been throwing off. Teitoku, through his dragonfly, learned that it could not find his target, and Teitoku made it focus its search on areas that could not be seen from sky. He begins expressing interest in Accelerator's wings, as it leaves the category of logic altogether, and can overwhelm his Dark Matter, making it the biggest danger against him. With little to go on regarding the wings, Teitoku needs to hold Accelerator's emotions in check when fighting him. And believes that even though he is fiercely powerful, an opening will open up for him. Then, Teitoku jumped off the radio tower, after determining that the surveillance from above is no use.

Teitoku leads Accelerator to the underground passageways of the lowest level of the multi-level overpass. Accelerator calls Teitoku pathetic leading him to ask him how far he has come after much has happened to him. Accelerator still calls him pathetic, saying that if he truly did gather everything for what he lacked, then he shouldn't care about that issue. Accelerator tells that he had enough, and said that despite all Teitoku had done to gain his power, he is still pathetic.

However, Teitoku then references the location they were in. He asks if the location they were in is familiar to him, but Accelerator could not answer. Laughing, Teitoku reveals that this was one of the stages for the Level 6 Shift, where Accelerator once mercilessly killed Sister clones. Before Accelerator could react, Teitoku has already created a change. Before them were several Misaka clones, speaking, acting, and moving like the Misaka clones that was there when Accelerator killed them an uncounted number of ages ago. Teitoku reminds him that they aren't actually them, as he forced his will upon them, turning towards Accelerator. He tells Accelerator that he cannot completely fix someone who has died, nor he can make something completely identical. He explains to him that he uses his Dark Matter to take information from an area, like a form of Psychometry, and give the information form.

Hesitation comes upon Accelerator, and Teitoku notes that it is actually working, much to Accelerator's anger. Teitoku relates on how esper powers are controlled using high level calculation ability, even unknowingly, and that throwing it out of order can be useful, like making him lose his reflection. However, Teitoku notes his interest in seeing those wings, and asks Accelerator to at least make himself be worthy of testing his ability. The Dark Matter Misaka clones are ordered to attack him, something that should not be a problem for him. However, Accelerator instead of taking them down head-on, instead dodges their attacks. It was due to him not wanting to hurt them, as they reminded him of his sin. Seeing his actions, Teitoku says that he is full of openings. He turns his arm into a giant wing, and shoots out sharp feathers towards him, hitting the Sisters on the way like spears, though he did not care. Accelerator was unable to evade in time, and his thoughts were unable to fully implement his reflection. He is wounded by one of the spears, and he was thrown into the air, though he managed to break his fall. Before him, Accelerator's anger boils, as the Sisters tries to enact their orders despite being torn apart by the spears Teitoku has shot out. Accelerator could not help but remember the sins he has done, as Teitoku continues to toy with him.

Teitoku tells Accelerator that he did much research regarding him, and tells him that even though it looks like he has atoned for what he did, and that Last Order has forgiven him, it does not mean that he has been completely forgiven. Continuing, he tells that despite him viewing the Sisters as an aggregate whole in the Misaka Network, he also believes that the Sisters' individual personalities should also be recognized, that should mean the overall will that has accepted doesn't matter, as "only the one who was killed can understand the feelings of the one who was killed," and that, there is no longer anyway he can determine if he has truly been forgiven. However, Teitoku tries to trick Accelerator even further, telling him that the clones that he has formed is the final piece that would allow Accelerator to determine what those he killed thought, but also tells him that no one would know of his sins if he killed them here.

His words pierce through Accelerator, hurtling his mind into disarray, and weakening his calculations. Not only was he unable to control his power, but he was not even properly carrying out the calculation. And with that, Teitoku attacks. However, a beam of heat and light pierces through into the underground passageways, killing one of the clones. It is Mugino Shizuri, who has come to the lowest depths. She berates Accelerator for his actions, enraging him. She tells him that he is being angry at the wrong person, and references Teitoku's words on how "Only the one who was killed can understand the feelings of the one who was killed," is correct but states that the clones Teitoku made in here isn't really them. She continues that it is not the likes of them, people who have killed others, to even begin understand what the dead feels as it is not their purpose. She states that Accelerator is incredibly naive to fall for a Teitoku's tricks, and asks if he thought that they might come back to life and that his crimes for killing them would be undone. She says that she has read about the clones, and that his reasons for killing them was not worse than her killing others for no reason. She tells him that they are both going to hell, but there are things he needs to do before he goes. She asks what he will do, telling him that she doesn't care if he allows himself to get killed, or retrieve the dead's dignity and peaceful rest from the desecrater before him, it is his choice.

Accelerator acknowledges this, regardless however, the clones before him is the final proof that those he killed ever existed. Shizuri replies that it is all the more reason, and him finding it acceptable for someone to steal and control the dead, then he should just let himself be killed as she will take care of everything. She then feels uneasy and tells Accelerator that he has to dirty his hands to give the dead a clean end. She references what Teitoku said again, and says that only the living can act based on their feelings for the dead, and rejecting that and running way is neither being honest or pacifistic, but plain cowardice. And with that, Accelerator is released from his stupor and tells her that he will destroy, that he will be the remnant to prove that those people he killed really existed.

Teitoku finally reacts after listening to them, and asks if they will stop thinking how the dead feel and stop thinking about it. Shizuri tells him that he will never understand, for he is someone who puts words in the dead's mouth for his own benefit and runs away from his feelings regarding the dead himself. She tells him that he is pathetic even though he is powerful, and would've been better if had remained dead for he would've been merely the esper that defeated her. Then, she tells him the reason she was in there with them. On how someone who pretended to be Frenda attacked her last night, and suspects him for it for he was the biggest factor from the dark side of Academy City active at that time and the interest in playing with the dead was the same. She tells him that she doesn't know what his purpose was with what he did, and tells him that she will make him pay for disturbing her grave.

And with that, their battle begins. Shizuri used her beam on Accelerator for his use, redirecting it to all the false clones Teitoku created at once, destroying them. Accelerator directs his attention towards Teitoku, and uses his vector powers to destroy all the Dark Matter spears he created. As he twitched, Shizuri fired at him, obliterating the top half of his body and most of his legs. However, Teitoku appears upon a wall, saying that he can recreate himself. Shizuri asks if he moved his flesh and blood organs into the floor before her attack. Teitoku redirects the question, and hints many possibilities now that he can replace and create practically anything with his power.

Accelerator does not care however, ripping apart the countless spears and redirected the signals in the center point in the puddle, but to no avail, as Teitoku states the network of his Dark Matter expands and information sent faster without direct wiring than he can destroy it. Despite this, Accelerator continues to try and destroy his Dark Matter, as Shizuri continued to assist him, Teitoku then asks how much battery time Accelerator has left, and is curious about the wings that no theory can explain. Teitoku just brags on how time is running out, and that he has no problem taking down Shizuri. They continued attacking destroying his head, but it is of no avail, as he tells them that he simply has an infinite supply of Dark Matter, and his inspiration is boundless, telling them that to reach him, they need to climb over the wall of infinity that continues on eternally. He then shoots out countless Dark Matter spears towards them.

Teitoku continues his assault, but time is running out, and Teitoku simply taunts them as his Dark Matter attacks continue to shoot out. But then, something happened; he stopped. Shizuri becomes curious, threatening to kill him. But Teitoku does not answer, as he too is confused. He then asks what Accelerator did, believing him to be the culprit. Then, Accelerator realizes something. He tells Teitoku that this was the effect of him being "infinite," and tells Teitoku that it wasn't him.

He did not know, but Beetle 05, the rogue beetle that Teitoku ignored, was beginning to take over. As the system begins to transfer authority to Beetle 05, Teitoku begins to crack, who cries on how it is not possible for a power that he brought betray him. Accelerator then tells Teitoku that it is no longer matters who was the first Teitoku, as he obtained in infinite. Shizuri too began to understand. She laughs at his problem of being too powerful, saying that when a network made up of flexibly replaceable equipment has a portion become isolated from the rest, the isolated portion becomes a small network of its own. Accelerator concludes that the one who stopped Kakine Teitoku was now the Kakine Teitoku. Accelerator is impressed on Dark Matter's capabilities, and mocks him for being unable to wield it. Shizuri however notes that he might not be the core Teitoku as he had scattered his mind over the system, and the one before them was closest to the surface, though it says of nothing that what showed itself in the surface was the true nature of Kakine Teitoku. Shizuri then asks if they were just battling the outer layer of his mind, and tells that it wasn't easy doing it. Here, she is impressed by Kakine Teitoku, being not a normal person, but not the one before her right now.

Slowly, despair overtakes Teitoku and slowly more cracks form. Accelerator comments on how there will probably nothing left to prove that he was here, and even if a massive amount of date is left concerning Kakine Teitoku, it will not refer to him. In his darkest hour, Teitoku recalls Takitsubo Rikou being part of the group when he attacked them for the first time. He also recalls on how she had the ability to track others' AIM dispersion fields, and that she also had the hidden possibility of using others’ AIM diffusion fields to distort their Personal Realities. A person he deemed to have been capable of becoming the eight Level 5. There, Teitoku realized that she might be the one, consciously or subconsciously, that have incited the change in Beetle 05. Teitoku is enraged greatly. He shouts his fury in that underground passageway with only Accelerator and Shizuri as his audience. Accelerator however, had enough, and pierced his center of the thing before them, completely shattering it, and the Dark Matter dissolved into the air, leaving nothing behind.

Mugino Shizuri is actually right in her assessment, as Kakine Teitoku's true flesh and blood organs have been kept in secret, and has somehow come into the possession of Ollerus. Disguised as Thor, he smuggles Teitoku's organs from Academy City, and brings it before Othinus, in hopes of fooling her into using it as a substitute for Fräulein, who changed into a form that is useless to them, as she can no longer become a Holistic esper. Ollerus tells Othinus that they can use him to create a doll that would act as a substitute for Fräulein, a doll that is tainted neither by science nor magic. Othinus takes Teitoku as a substitute, after punishing "Thor" for failing to acquire Fräulein for her.

Abilities
The angelic nature of his ability is described as "The One Who Has Touched the Territory of God" (「神が住む天界の片鱗を振るう者」), and just like Accelerator, Aiwass has shown great interest in Teitoku's now torn-apart body. Kihara Yuiitsu, who has studied Accelerator and Teitoku, compares the two with the duality of Destruction and Production.

Original incarnation
Dark Matter (未元物質 (ダークマター) ), is his esper ability which allows him to create and control an unknown material that he uses to attack. It should be noted that the term "Dark Matter" is not to be confused with the true "Dark Matter" which is among the components of the universe. In addition, 'unknown matter' here does not mean matter that has not been discovered by humans but matter that did not exist until it was created by Teitoku. The material he creates defies the Laws of Physics. It also grants him flight capabilities. When fighting Kinuhata Saiai, he is also able to utilize his ability to create a strange explosion which is able to instantly knock Saiai out. His Dark Matter can initially even strike through Accelerator's Reflect, though after Accelerator took into account how 'normal' physics don't work on Teitoku's ability he re-calculated and managed to reflect Teitoku's Dark Matter, and even use it against him later. His ability also appears to grant him a form of super strength, though he is still not strong enough to overpower Accelerator with sheer brute force.

Revival
After his revival, it was revealed that he can now seemingly infinitely create a variety of objects using Dark Matter, even organs. Teitoku reveals himself to be able to create a body made out of pure Dark Matter, making him white in the process.

In this seemingly infinite supply of Dark Matter, Teitoku can apparently survive so long as there is Dark Matter. He can create autonomous beings such as a copy of his own body, bodies of other people, and cyborg-like beings like the White Beetles and dragonfly. Teitoku also implies that it is only a matter of time that he can construct full Personal Realities, seemingly real people, and make implementations of other people’s powers before long.

There is a sort of "network" to his creations, where he has some form of control over them and allowing them regenerate their Dark Matter when they are injured. This connection to the network allows Teitoku to live through, despite the destruction of the current core of his form. Effectively, there is now no distinction between the Dark Matter Teitoku produces and Teitoku himself, and it could be said Teitoku has achieved a sort of "immortality".

Residual Thought
One of the queer powers that Teitoku has learned is the ability to run his Dark Matter in an area's surface, to obtain information of past events, like a powerful form of Psychometry. Moreover, through the use of Dark Matter, he can give them shape. It is like a CD where individual tracks refer to each unique information gathered. With this simile, it would be like he can allow the shape to "play" the track that was gathered by him.

Flaws
Originally, his brain, that he somehow left behind and did not carry with him, produced Dark Matter through his Personal Reality. However due to the fact that he has essentially made himself immortal and infinite through the use of Dark Matter, allowing other parts to be referred to as Kakine Teitoku, there was no longer an issue for whomever the brain referred to. This would normally not be a problem, since Teitoku seems to still have no ability to create things with Personal Reality, a being with will of their own, to forcibly refer to itself as Teitoku. However, when Beetle 05, came into contact with Rikou and her AIM Stalker, an esper power that is predicted to manipulate Personal Realities, Beetle 05 became isolated from Teitoku's network.

When a network made up of flexibly replaceable equipment, like Teitoku's "network", has a portion become isolated from the rest, the isolated portion becomes a small network of its own. As such, it also becomes referred to as a "Kakine Teitoku," and if so chooses, can take over the entire network, and be referred to as the Kakine Teitoku.

Equipment

 * Pincet Glove: Is the claw that Kakine Teitoku wears on his right hand, it is the tool he uses to grab nano-sized matter. Teitoku used it to capture Underline, the nano-machine which Aleister Crowley used to monitor Academy City. It should be noted that the glove was originally a large, bulky piece of machinery, but Teitoku modified it by "only leaving the truly necessary parts" greatly diminishing it's size and weight. Tsuchimikado Motoharu took it off of his body after he was defeated by Accelerator and analyzed the information in the Underline stored in the glove, which led to GROUP's discovery of DRAGON.

Design evolution
Haimura designed Teitoku around the idea that like a backup yakuza member and a host in a host club, giving him a look like someone approachable but would immediately turn to someone that would threaten you, opposite to Accelerator, who has an aura of danger around him.

His design for his return form is the same as his original design apart from his body being made of black and white colors.

Trivia

 * Fans usually depict Kakine Teitoku in various works as a man - or in rare instances, a brain with three pairs of wings - inside a refrigerator. This is a reference to how his brain was restored by Aleister Crowley in order to utilize his esper ability beyond his death. Mugino Shizuri describes the device Kakine Teitoku is strapped to as a refrigerator-like device.
 * It is stated in the narration in volume 15 that Accelerator controls the organic while Dark Matter (Teitoku) controls the inorganic of a higher plane. In addition to this, it is stated that Accelerator's wings are made of the same Dark Matter that Teitoku creates with his ability, according to his observation.

No matter how many cards you gather in your hand, I can push it back with brute force as numbers means nothing to me. …Nothing you do will ever even reach me. To reach me, you first need to climb over the wall of infinity that continues on eternally."

I guess that was the extent of Academy City’s society."
