The battle hungry Captain of Division 11
Kenpachi is a giant of a man, towering over most of the other captains and all of the human spirits that invade the Soul Society. Kenpachi Has his hair spike up and attaches bells to the ends of his hair. Besides the traditional black outfit that the Soul Reapers wear Kenpachi wears his captain's jacket without sleeves. Kenpachi also has an eye patch over his right eye. Kenpachi carries around an abnormally long Zanpakuto with a short handle for it's blade length.
Besides people who are stronger than himself Kenpachi's only real weakness is his inability to determine where he is and where he wants to be. That's correct Kenpachi has no sense of direction and usually relies on his lieutenant Yuchiru for directions, even though she also lacks a sense of direction.
Along with the inability to know his zanpakuto's name Kenpachi can not use his swords full power and therefore has yet to reach his full potential. Kenpachi is very close with his Division and acts almost like a father figure for them. Kenpachi take cares of his men and tends to talk to each of them. Kenpachi seems to have all of his men's respect by the way they look up to him and believe in his strength, all rallying under him for guidance when the Soul Society is invaded by Ichigo's team.
Kenpachi is first seen in Bleach as a side character with Gin Ichimaru taunting Byakuya Kuchiki, hoping to start a fight.
Kenpachi was a nameless warrior originally from District # 80 of Soul Society, also known as Zaraki (which is where he got his surname from). District 80 is the worst and toughest region of Rukongai. During his time in District 80, Kenpachi became a skilled and proficient swordsman and killed countless enemies.
At some point during his travels outside of District 80 Kenpachi found a small girl and named her Yachiru, in remembrance of the only person he ever admired because she showed no fear of his sword. Yachiru came from District 79 and was living by herself since her parents were murdered. On that day, Kenpachi took his first name: Kenpachi, which was the title bestowed upon the strongest swordsman, the one who has killed the most. The two are close and have a father-daughter-like relationship and Kenpachi even made Yachiru his lieutenant when he became a Captain.
It is seen that Kenpachi is a warrior who craves battle by what is shown of his past in Bleach. He came from the most dangerous and violent district in the Soul Society and perfected his sword fighting skills there. He also meets his future lieutenant, Yachiru Kusajishi, while he traveled about fighting and killing whomever he thought worthy of battling himself.
Up until this point Kenpachi was nameless, taking the name Kenpachi because he had earned the most kills as a swordsman. Kenpachi went on to go through the training to become a Soul Reaper, and joining the Soul Society's army. Kenpachi served in the 11th Division before he became the 11th Captain. Kenpachi earned his captain seat by the third method of advancement in the Soul Society, Kenpachi killed the former captain. As a sign of his rank Kenpachi wears the jacket of the captain he killed.
Kenpachi's Abilities are revealed steadily throughout the Soul Society Arc and can be demonstrated through connections that are shown through the lengthy part of the series.
When Ichigo and the others invade the Soul Society, Kenpachi is the first Captain that Ichigo runs into. Kenpachi challenges Ichigo because he is the most powerful of the human souls that entered the Soul Society.
Kenpachi fights Ichigo in a brutal battle with Zanpakutos. During the battle Zanpachi reveals that he doesn't release his sword because he constantly fights at a released level. Zanpachi reveals after the battle that he doesn't know his Zanpakuto's name. Since Kenpachi doesn't know his Zanpakuto's name his sword looks chipped and battered from all his battles.
Despite it's appearance Kenpachi's sword is very powerful and can even slice through other Zanpakutos, like he does to Ichigo. Kenpachi reveals that his sword is coated in his energy which gives it power to attack like a release form despite it's looks. Kenpachi can release energy through his blade in many forms even as a blast of energy that can be generally aimed at an opponent with no great accuracy.
Kenpachi feels sorry for his sword because it doesn't have a name, like he didn't before he named himself Kenpachi. Kenpachi has an immense amount of stamina, which he demonstrates in both his battle with Ichigo and Tosen. Kenpachi continues to fight Ichigo, no matter what Ichigo throws at him, until he can't stand anymore. In his fight with Tosen Kenpachi demonstrates his resilience when he survives Tosen's released Zanpakuto art, which cuts all senses off from the opponent.
Kenpachi show he has a knack for on the spot strategy by realizing that he could still use his sense of touch and gain full use of his senses while in contact with Tosen. Kenpachi's strength and strategic genius prove too much for Tosen and forces him to step out of the battle. While fighting Ichigo Kenpachi lets his full power lose, revealing that he does hold back a lot when he normally fight.
Like all Soul Reapers Kenpachi's strength is much greater than most human's have. Unlike most Soul Reapers Kenpachi has strength and speed greater than most of the other Soul Reapers have, too. Kenpachi can increase his power when he is fully ready to release his inhibitions and just go for the kill, like he does shortly before losing to Ichigo.
Ater a long absence from the series Kenpachi and three of the other captains return to the storyline in the middle of the Arrancar duels. After Nel and Ichigo fall victim to Nnorita's incredible power and stamina Kenpachi steps in to do battle. Excited to meet a powerful enemy Kenpachi attacks without hesitation. It seems like he has fought his way to victory quickly as he shoves his zanpak- to through Nnorita's head, but the battle doesn't end so easily as the eye patched Arrancar shoves his hand into Kenpachi's gut. Unfazed by the attack Kenpachi begin attacking with happiness as he has found a foe that has proven to be more powerful than him. At one point Nnorita knocks Kenpachi down and starts to think he has won and heads towards Yuchiru, who points out that Nnnorita should turn around and finish his duel with Kenpachi. Kenpachi continues to attack recklessly, cutting up his foe while taking his own wounds. Eventually Kenpachi realizes that the Arrancar is going to win if he doesn't get serious.
Placing both hands on his Zanpaku- to's hilt Kenpachi uses a kendo two handed sword slash to down his enemy. The blast of his sword hitting Nnorita creates a massive geyser of sand and wind. The attack also nearly cleaves Nnorita in half, but the Arrancar manages to hang on to life by a thread, and admonishes Kenpachi for not killing him. Tired of hearing his talking Kenpachi agrees to one final attack against Nnorita and finishes him off.
Once the fight has ended Kenpachi tells Ichigo to get his zanpaku- to and Orihime to heal him, but everything he had fought for turns south as Stark kidnaps Orihime again. As Aizen unveils his plan to destroy the human's hometown Kenpachi stops Ichigo and explains that the city is not without protection as the other Gotei 13 captains and their lieutenants are waiting in wait for Aizen to show up.
Later Kenpachi, alongside Byakuya arrives to the battle between Yammy and Ichigo. After Byakuya attacks Yammy with a huge Kido spell, Kenpachi cuts off one of Yammy's legs, making him fall over. He then berates Byakuya for "stealing" the first blow and tells him to get away from the battle area. Byakuya calmly calls his statement nonsense, since he was the first to arrive and that Kenpachi should learn his place. Kenpachi however ignores Byakuya and tells him not to complain then if he get sliced into pieces alongside Yammy.
Kenpachi then tells Ichigo he is a disgrace as he seems to get "beat to hell" everywhere they go; he then tells him to move out of the way. When Ichigo stares at him confused Kenpachi goes to strike at him, but Ichigo dodges and screams at him that he could have killed him. He then goes and charges at Ichigo but is slapped away by Yammy and sent flying into a nearby structure. As Yammy rants and raves, Kenpachi kicks a large piece of rock at him but the Espada crushes it to rubble before it can make contact. Kenpachi then states that he is surprised that Yammy can throw a decent punch when he wants to as he barely felt it when he hit him. He then tells Yammy that even though he must think he is a big fly, if he is going to punch him he better put some effort into it. Yammy then enraged goes on to attack Kenpachi.
Kenpachi has several leaders under himself that greatly respect him and admire him and one that befuddles him. Kenpachi's lieutenant is as mentioned Yuchiru Kusajishi, a young girl that isn't even half his own size.
Ikkaku Madarame, a bald Soul Reaper who is close to some of the other lieutenants and a strategic fighter. Then there is Yuichika Ayasegawa, a flamboyant subordinate who has a very strange release power.
Yuichika is the only high seat officer in the 11th division that Kenpachi has a hard time understanding because of Yuichika's obsession with his own beauty. After battling with Ichigo Kenpachi becomes allies with the human warriors. Kenpachi is also known amongst the other captains in the Soul Society even if the don't get along with him because of his desire to fight and destroy.
Focusing on sheer power and his great swordmanship, Kenpachi does not rely on many other forms of Shinigami combat (such as kidou or shunpo) that is commonly used by other Shinigami. It is only in extreme situations that he may consider to adapt other forms.
Kenpachi is the only Captain of the Gotei 13 who has not learned his zanpakutō true name let alone his Bankai. However his powers are such that should the day we witness his zanpakutō's release, Kenpachi would most likely become the most terrifying Shinagami in existance.
Despite not knowing its name his Zanpakutō is constantly released in some form of released state due to his immense Spiritual Pressure. His Zanpakutō is constantly in a Shikai state without having the additional abilities a Shikai may grant its user. The sword's appearance is a reflection of Kenpachi's own practice of weakening himself to fight others on a even level: it is a chipped and seemingly worn-down blade with a guard that extends inward from its center similar to a shinai. The hilt is white although most of it is wrapped in bandages, as is his sword's sheath. The blade is much longer than that of a standard Zanpakutō, roughly the size of a nodachi. Despite its appearance, it is easily capable of cutting through most objects. This is demonstrated when he stabs straight through Ichigo's Zanpakutō and later slices a building in half with careless effort after releasing the full force of his spiritual power.
