— Kenny reflects on his life[2]

Kenny Ackermann (ケニー・アッカーマン Kenī Akkāman?)[3] was the captain (隊長 Taichō?) of the Anti-Personnel Control Squad in the Military Police Regiment. Kenny was a former serial killer who would slit his victims' throats, considered by some to be an urban legend known as Kenny the Ripper (切り裂きケニー Kirisaki Kenī?). After meeting and befriending Uri Reiss, he worked for the crown, but secretly desired the "God-like power" that the Reiss family had possessed for himself. He was the maternal uncle of Levi Ackermann, and raised and taught the latter as a child how to survive.


Kenny had shoulder-length brown hair with sideburns, a thin beard along his jawline, and gray eyes. He was a very tall and slim man who appeared to be well-built. He had the appearance of a middle-aged man with wrinkles around his eyes, which are small and piercing. He wore a simple white shirt with a black vest overtop and black pants, along with a fedora hat. He was also seen wearing a fashioned black trench coat, along with his standard attire and fedora hat. He was almost always seen wearing a pronounced scowl, even when making a foul joke.

When he was younger, Kenny had a more defined face and much fewer wrinkles. He did not have a beard but he still had dark sideburns. Also, his hair seemed to be slightly longer. He used to wear a long coat, dark trousers and shoes, a white button shirt and another hat.


Despite his previous life as a serial killer, Kenny appeared to be a rather jovial man. Even in the midst of battle, Kenny had no trouble remaining cheerful, seemingly taking pleasure in taunting his adversaries. He had also proven to be rather animated in how he behaves, yelling and making a scene when he corners Levi in a tavern, and throwing furniture to try to provoke Levi. Despite this, he could seemingly control himself when he needed to, being able to sneak up on his targets without them noticing him.

Kenny had also proved himself to be very cold, showing no emotion when he kills his prey. He also seemed to hold very little emotional attachment to those close to him, having no qualms with trying to kill Levi, despite having raised the man as a child.

Kenny wanted power, and his personality was molded around this goal. He was a ruthless individual who did not hesitate to do anything to get the job done, including murdering children or betraying his allies. He operated with utter professionalism, hiding his emotions behind a fixed expression and showing neither remorse nor pleasure in his mission. He also showed a strong impulse to kill Uri Reiss when they first met.

Kenny sought after power

Kenny expressed a desire to live a "fun" life, but had a strange idea of what he considered "fun," commenting that he believed his grandfather's story about the Ackermann family's history because it would be more fun to do so, and commenting that growing old and living a full life did not sound fun. The only thing stranger than his idea of fun was his sense of humor, seen when he said that his grandfather's story about the persecution of the Ackermanns was "funny," and when he freed Eren Jaeger in order for him to fight against Historia just for his own entertainment, even though the future of humanity was at stake.

Even so, he was able to show true admiration and respect to those who he believed deserved it, like Uri or Caven, his second in command. He could also be seen at time displaying genuine care for others, killing MPs that came near his grandfather's home so that they would not harass him, and raising his nephew Levi following his sister's passing. This care for others could also be seen briefly in his interactions with Historia in the Reiss chapel, becoming noticeably saddened to see Historia's slavish devotion to her father's will, despite the consequences that she would face if she followed through with is plan to inherit the Founding Titan. Though this is not to say he was overly caring. He disliked cowards and did not respect them, and cared even less for titles, not hesitating to threaten Rod Reiss, the true king of the Walls.

Kenny abandons Levi

Kenny later revealed that he only obeyed Rod as a plan to obtain power, and that his true intentions were always to become a Titan and gain the Founding Titan himself, which was in direct opposition with Rod's goals. After witnessing Uri and later Frieda Reiss become benevolent people after inheriting the Founding Titan, he wondered if the same thing would happen to him too. He wanted to know what does it feel like to be kind and compassionate. His grand dream was to take the Founding Titan and see the world like Uri once did.

Despite his outward confidence, Kenny seemed to suffer from some degree of self-loathing, going so far as to describe himself as "garbage." His poor view of himself seemed to stem largely from a dissatisfaction with his own lack of empathy towards the lives of others, as his entire quest for power was motivated by a hope that gaining more power would make him a more compassionate person like Uri. His self-deprecating nature also manifested itself in a lack of self-confidence, demonstrated by his decision to abandon Levi when the latter was still a child because of his belief that he was not fit to be someone's parent.


At some unspecified point, either before or after becoming a serial killer, Levi recalls Kenny saying he felt a sudden inexplicable surge of power and with it he knew "exactly what to do."

Kenny made a name for himself as a mass murderer, infamous for having managed to kill over 100 members of the Military Police Regiment.

Kenny talked with his grandfather

One day, after having killed some MPs who were snooping around his grandfather's house, Kenny went to visit his grandfather. He informs his grandfather that he has learned of a branch of their family that is living in Shiganshina District, but notes that they are impoverished due to interference by the MPs in their area. Reminding his grandfather that their family used to serve the king, he demanded to know why they are now being treated the way that they are. His grandfather explained that the king fears their family, because they are immune to his power which allows him to alter the memories and control the people of the Walls, and control them and that they faced persecution because they, along with the Oriental clan, chose to turn their backs on the king's ideology.

Kenny also informed his grandfather that he had managed to find his sister, Kuchel, working in a brothel in the Underground. He was unhappy to learn that Kuchel had been impregnated by one of her clients and that she intended to keep the child, and sullenly mused that there was no dream worth living in the world that they did.[4]

Kenny was caught by Uri

Sometime after that conversation, Kenny talked with a contact in the government, who informed him of the existence of the Reiss family, the true royal family within the Walls. Kenny tracked down Uri and Rod Reiss and tried to kill them, but failed when Uri partially transformed into a Titan and trapped him in his hand.

Though Rod tried to shoot Kenny while he was immobilized, Uri stopped him, wanting to interrogate him to discover the identity of his contact; finding Kenny's hatred towards them justified due to the persecution that the Ackermanns suffered at the hands of the monarchy.

Kenny is shocked to see Uri bow to him

Kenny attempted another attack by throwing his knife at Uri, though the latter stopped it with his arm. Seeing this, Kenny started screaming at Uri, asking for another chance to prepare a proper ambush. To Kenny's shock, Uri released him, and even bowed before him, apologizing for the persecution towards the Ackermanns and pleading him to spare his life. Kenny was surprised to see this coming from a king with that much power, and offered to help Uri, which the latter accepted.

Kenny became Uri's bodyguard and close friend, and remained at his side until the latter's death. After some years, he returned to the Underground to see Kuchel, but found that she had been dead for some time. He found, and then adopted, her son Levi but introduced himself to Levi as a close friend of Kuchel's, without revealing that he was Levi's uncle. Kenny lived with Levi and trained him, teaching the boy everything he knew about how to survive. Once he was reasonably sure that Levi would be able to survive on his own, Kenny abandoned the boy without saying goodbye, feeling that he was unfit to be a parent.

Kenny and Uri talked by a lake

Years later, Uri explained that he would not be long for the world, and he would be passing his powers to some of Rod's children, but that he would live on in their memories. Uri told him that he saw the world as ending in some time but before it happened, he wanted to make a paradise for mankind.

After Uri passed the Founding Titan to his niece Frieda and died as a result, Kenny made a plan to obtain the same Titan powers Uri had and used his influence to establish the Anti-Personnel Control Squad. On his first day as captain, Kenny introduces himself to his new subordinates, acknowledging himself to be the man who slaughtered many of their comrades when he was still a serial killer. However, one of the soldiers, Caven, speaks up, explaining that his past did not matter to them. She explained that they had given up on killing Titans, and the only remaining alternative to them was killing humans. Caven's words greatly pleased Kenny, and he began to single her out as his favorite soldier and second in command.[2]


The Fall of Shiganshina arc

In the year 845, days after the fall of Wall Maria, Kenny arrives with a group of soldiers at Historia Reiss's home. He grabs Historia's mother and asks Rod Reiss if she and Historia are related to him. Rod Reiss denies it and Kenny slits Alma's throat. He approaches Historia to kill her too, but Rod Reiss orders him to stop and saves her life, giving her the new name "Christa Lenz" to live by.[5]

The Uprising arc

Tasked with bringing Eren Jaeger and Historia Reiss to Rod Reiss, Kenny and Caven begin staking out the cottage that Levi's squad is staying in, and the experiments conducted on Eren's Titan form.

The two watch as Military Police unsuccessfully attempt to raid the cottage and detain its occupants, with Kenny commenting that Levi was able to mobilize his subordinates fast enough to avoid capture because of his training.

Kenny aims his guns at Levi

Kenny follows Levi's squad to Trost District, where he employs the help of Dimo Reeves and the Reeves Company to kidnap Eren and Historia. Although the locals kidnap decoys, Kenny sees through the ruse and tracks down the real Eren and Historia. Seeing that Levi is keeping watch over the covered wagon that Eren and Historia are in from afar, Kenny flanks Levi and his companion Nifa in order to kill them. Although he is successful in killing Nifa, Levi anticipates Kenny's flanking maneuver and manages to survive his attack.

As Kenny's subordinates kill another of Levi's companions, Kenny jovially insults Levi's small stature as he reloads his guns and uses his ODM gear to get another clear shot.[6] Levi manages to escape, dodging Kenny's gunshots as he flees. Kenny's squad pursues Levi, eventually forcing him to take shelter in a nearby tavern.

Kenny enters the bar

Kenny follows Levi into the tavern, but is not able to find him. Concluding that Levi is not there, he is caught off guard when Levi begins to talk to him from under the counter. Levi expresses amazement at Kenny's working with the Military Police, but Kenny brushes him off, claiming that he would not understand such adult matters. Kenny continues to taunt Levi, criticizing his decision to join the Scout Regiment and throwing chairs over the bar to antagonize him. As he tries to get closer to Levi, Levi shoots him with the tavern owner's gun. Kenny manages to block the bullet with a chair, saving his life, but is knocked out of the tavern by the force of the impact.

As Levi makes his escape, Caven comes to check on Kenny. Kenny notes Levi's growth since they last parted, and laments that his dream is slipping away from him. Having personally given up the pursuit of Levi, Kenny delivers Eren and Historia to Rod Reiss.

Kenny kills Reeves

Learning that Reeves has double-crossed the Military Police and sided with the Scout Regiment, Kenny tracks down Reeves and, under the cover of night, kills him. Caven is concerned that he did not attempt to find out Levi's location from Reeves, but Kenny assures her that Levi will eventually come to them.[7] A day later, he would oversee members from the Scout Regiment being arrested while reminding Caven that Levi will show up on his own eventually.[5]

In the cavern under the Reiss Chapel, Kenny listens on as Rod helps Historia unlock her memories of her sister Frieda, and Eren his memories of his father's last moments. As Historia absorbs the information, Kenny reveals himself, and informs Rod that the military has switched sides, overthrown the puppet king, and taken over with Dhalis Zachary in charge. He encourages them to hurry, as they are almost certainly being pursued. Rod orders Kenny to take his squad and guard the entrance to the chapel, as he can only move forward once the Anti-Personnel Control Squad leaves. Clearly displeased, Kenny tips his hat and departs. As he leaves, he recalls one of the last conversations he had with his grandfather.[4]

Kenny arrives to fight Levi

Kenny arrives at the mouth of the cavern to find his squad engaged with Levi's, arriving just in time to save Caven from Levi. Like in their previous encounter, Kenny tries to flank Levi, but this time Levi is ready to counter him. Kenny begins firing at platforms stationed throughout the cavern, distracting Levi with the debris created in order to get in close and attack him with his knife. As Levi tries to get out of range Kenny fires at him again, but Levi uses a pouch of gasoline to block the blast, creating an explosion. Levi uses the cover provided by the explosion to get in close with his swords, and although Kenny is able to block the majority of Levi's strike with his knife, he is still dealt a sizable cut to his midsection. Kenny and his squad retreat farther into the cavern, with Kenny firing off one last shot at Levi as he flees.

Kenny returns just in time to hear Rod reveal to Historia that the Founding Titan's power can only be fully realized by a member of the Reiss family. He asks Rod to confirm what he just said about only a Reiss being able to obtain the Titan's power, which he does. Having planned to become a Titan himself and steal Eren's power, Kenny becomes visibly distraught as he realizes that his plan is pointless.

Kenny turns on Rod and threatens him with his gun

Growing angry, he lifts Rod into the air by the collar and begins to threaten him, upset that Rod knew his intentions and strung him along. Rod replies that he is grateful but also that he was unaware why his brother ever took "a dog like you" off the streets. Kenny interrupts him and says that if he insults Uri once more, he will blast Rod's face in half. Historia knocks Kenny's gun away, demanding that he let go of her father. Kenny reminds her that Rod is trying to turn her into a monster who will eat Eren, but Historia replies that she will do it if it is her mission, adding that there is nothing sad about saving humanity. Kenny reminds her what Rod did to her; that her birth was a tragedy and only conceived because Rod wanted to feel good with a servant. Kenny does not believe the notion that Rod saved Historia out of love and claims that he only did it because Grisha killed the rest of his children and he needed Historia's blood, which is why the Order of the Walls had been keeping an eye on her.

Kenny begins shoving a knife down Rod's throat as he claims that Rod did not want to turn himself into a Titan and so used his family. Kenny goes on to say Rod covered up the theft of the Founding Titan's power in order to keep the Reiss family in power, and did not start talking until after Eren saved Trost District, which was only after innumerable sacrifices. Finally, Kenny mentions that Rod only truly cares about protecting himself and not his family, humanity, and especially not Historia. To Kenny's surprise, Rod is able to pull the knife out of his throat and tells Historia that Kenny is wrong. He admits that he has not told Historia some things but does reveal that he can not become a Titan himself for an unspecified reason.

Kenny removes Eren's gag

Kenny releases Rod, and Rod tells him that he is free to leave and should go live a long life. Kenny sullenly remarks that Rod's suggestion would not be very fun, before ascending the stairs towards Eren, telling him to turn into a Titan, to the horror of the two Reisses. Kenny says that both Historia and Eren can become Titans and fight to the death, with peace returning if Historia wins and nothing changing if Eren wins. He slices Eren's forehead to help him transform, and asks Rod if he can truly call dying of natural causes living.

Kenny uses his ODM gear to pull himself up to a safe distance while remarking to himself that he should get away from what is about to happen. However, Kenny gets very surprised when Historia hesitates to inject the serum. He even starts laughing after Historia rejects the serum, harms her father and tries to release Eren, cheering the two for making things far more interesting.[8] However, when Rod transforms himself into a Titan, Kenny gets dragged by Rod's heat and sheer size, cursing Rod for becoming a Titan. As Kenny tries to escape using his ODM gear, he sees his squad coming towards him. He tries to warn them to stay away, but is only able to watch as they are crushed under the falling debris.[9]

Kenny rests against a tree

While his squad is crushed in the falling debris from the cavern, Kenny manages to survive and escape. However, he is heavily injured in the process, receiving severe burns all over his body from Rod's transformation. As he exits the remains of the cavern, Kenny slowly makes his way to a nearby tree, where he takes off his armor and collapses. As he rests, he recalls the day that he abandoned Levi as a child, but his reminiscing is interrupted by the arrival of Levi himself. Levi observes that Kenny's injuries have left him on the verge of death, and Kenny responds by smugly revealing that he has a Titan injection, which could allow him to save himself.[10]

Kenny passes away

Levi is confused as to why Kenny has not already used it to save his own life. Kenny claims that he was afraid of ending up like Rod, but Levi is not convinced and asks if he has a better explanation. As Kenny tries to think of one, he recalls all of the important people of his past, and comes to the realization that they all had something that drove them, which he has lost. At the brink of death, Kenny confesses that he is Levi's uncle, explaining that he left Levi because Kenny viewed himself not fit to be a father. As a final gift, Kenny gives Levi the Titan injection that he stole from Rod. Soon after, he dies, sitting under the tree where he rested.[2]


Kenny was an infamous serial killer within the capital who murdered over a hundred members of the Military Police, implying exceptional battle prowess. On top of that, he was the leader of the Anti-Personnel Control Squad, showing high leadership skills. He seemed to have been an adept teacher, as he was able to teach an individual as skilled as Levi how to out-maneuver his targets and everything he knows about survival and combat prowess. When Levi felt the possibility of facing his old teacher, he was very uneasy despite going head-on against Titans on a recurring basis, which further suggested Kenny's exceptional combat powess.


Kenny was highly intelligent and analytical, and a quick and strategic thinker, having been the mentor to Levi Ackermann. He was much more cunning than the average member of the Military Police, thwarting Levi's plans to discreetly transport Eren Jaeger and Historia Reiss, while also positioning his team so they were able to eliminate nearly all members of the Scout Regiment's Fourth Squad.[6][7]

Anti-Personnel omni-directional mobility gear

Kenny was highly skilled at using his squad's Anti-Personnel omni-directional gear, enabling him to land quietly enough behind Levi and Nifa that he was able to kill Nifa before she realized he was there.[6]


  • Levi Ackermann - Kenny trained Levi when they were younger, and they even lived together. He appeared to have some respect for his nephew since he called him "his pride," but he still abandoned him once Levi could take care of himself, feeling that he could not be a good parent to him. Kenny had no difficulty attempting to kill him when Levi got in his way, but even after all those years he still seemed to care about him, leaving Levi with the Titan injection as a final gift before dying. Before dying, he also reveals to be Levi's uncle, who took care of him after his mother, Kuchel Ackermann died.
  • Uri Reiss - When they first met, Kenny tried to kill him without the smallest bit of hesitation. However, after he spared his life and went so far as to apologize to Kenny for what his family had done to his own, Uri ended up becoming one of the most influential people in Kenny's life. Kenny became incredibly loyal to Uri, and respected him so much that he threatened to kill Rod Reiss simply for disrespecting him. Kenny's entire plan of capturing the Founding Titan for himself was motivated by his desire to become a more compassionate person like Uri himself, and to see the world as he once did.
  • Kuchel Ackermann - Despite being her brother, they were not very close and weren't on good terms with one another. When her pregnancy was announced, Kenny persuaded her to lose the baby, but she did not listen. Although he was distant from her, Kenny did clearly care about his sister, as he was heartbroken at the sight of her death, and went so far as to raise the son she left behind in her honor.
  • Rod Reiss - Though initially Kenny seemed to be loyal to Rod, being a sort of "right-hand man" for him, it was later revealed that he does not like him at all, believing that he is a coward that only cares about himself, and only obeyed him because he wanted to steal the Founding Titan from him. When Rod revealed that the Founding Titan would be useless if it were not used by a member of the Reiss bloodline, Kenny showed his true colors and did not hesitate to insult and threaten Rod.
  • Historia Reiss - Kenny killed her mother, Alma, without hesitation and was going to kill Historia had Rod not intervened. Years later, he insulted her when he captured her and Eren, saying that in the five years since he last saw her, she has barely grown. However, he appeared to pity her, as he tried to tell her that Rod was going to make her turn into a Titan and eat Eren and told her that Rod was a liar and a coward.
  • Caven - Kenny held great trust in all his soldiers, but he was especially impressed by Caven's professionalism and unwavering loyalty. He eventually saw much promise in her and designated her as his second in command.
