Kon

Ichigo's personal mod soul at the start of the series.. His name is short for. Kon originally wanted the name "Kai" ("Mod" in the official English dub) because it sounded cooler, but Ichigo Kurosaki decided his name was going to be Kon for that very reason. Kon is an artificial soul (modsoul) designed to inhabit Ichigo's body when Ichigo is in his Shinigami form; when not serving that purpose, Kon usually inhabits a lion plushie, which he calls his "sexy body".

Character Outline
Kon primarily serves as a comedic foil in the series; when not inhabiting Ichigo's body, his normal plushie body is treated with little respect and much disdain. His plushie body is the fake copy of the main character of the popular TV show, "Carnivore Kingdom" named "Ponkichi". It was a prize from the shooting game in the Karakura Town Festival. He is constantly stepped on and torn, at which point Ichigo will have Uryū Ishida repair the plushie. Uryū usually adds something unwanted or unnecessary when doing so, such as dressing Kon up like a designer doll. Uryū also sewed a Quincy cross on the back of Kon's head as revenge after Kon attacked Uryū for turning him into a doll. He is quite perverted and often takes advantage of his form to get girls to hug him to their chests. He likes Rukia a great deal, and calls her 'nee-san', or older sister. He also appears at the end of every episode during the Soul Society Arc, giving a short course on individual members of the Shinigami.

Kon is a notable pervert as seen in three episodes: the first of which is when he falls in love with Orihime Inoue simply due to her huge breasts; the second is when he is stepped on by Rukia and comments on the advantages of being a teddy bear because one eye could see under Rukia's skirt (Note: he has also done that to Rangiku Matsumoto); and when he wished to be appreciated he called Orihime's breasts the "land of the goddesses" ("valley of soft pillows" in the English Dub). He nearly loses his temper and attacks some students after hearing them talking about deleting a character on a video game and replacing it with a new one, something quite similar to his current situation, granted that Yuzu Kurosaki tends to dress him up in feminine clothing and calls him 'Bostov', he seems to genuinely care for her well being as seen when Yuzu was crying in her sleep due to Ichigo's disappearance (In actuality he was training with the Vizards) he had expressed his disgust due to Ichigo's apparent lack of care for his family.

Personality
Kon has a deep disgust for people who have absolutely no regard for what they create, living or otherwise. This is shown in the episode he first appears in, when he attacks three kids who disregard the deaths of their characters in a Gameboy game. He behaves like this because of his own death sentence from Soul Society. Kon claims that he is incapable of killing anything, so much so that he went out of his way to kick an already defeated Hollow's falling corpse in another direction so it would not land on an ant hill, which would obviously crush/kill the ants. This kind act was the sole reason Ichigo decided to view Kon as a friend and requested Kisuke Urahara not to destroy him. Kon is also very perverted, as he is seen using Ichigo's body to please himself in chapter 182, and in many other chapters, is seen imagining/dreaming girls/women like Orihime and Rangiku fully naked, and sometimes together.

History
On the day of his birth, Kon was sentenced to death by the Soul Society as all the other mod souls. He was lucky to get with other products by mistake. After the fight with the Hollow, Kon tells Ichigo that he doesn't want to hurt anyone and that he considers himself equal with all Humans.

Agent of Shinigami Arc
Kon's first appearance is shortly after Rukia Kuchiki and Ichigo obtain a like item known as gikongan (Soul Candy) from the Urahara Shop, which are candy-like orbs stored in dispensers similar to those Pez come in. The Soul Candy, when ingested, forces Ichigo's soul out of his body and replaces it with an artificial, pre-programmed soul, allowing Ichigo to transform if Rukia is not around.

Unbeknownst to everyone (including the Urahara Shop's employees), the particular Soul Candy dispenser Urahara gives Rukia had been declared defective by Soul Society, as it was made from a batch meant to be turned in for destruction. These pills contained mod souls, artificially created souls designed to combat Hollows. Additionally, these souls have personalities, unlike the common artificial souls. Each modified soul was designed to have their own special strengths; in Kon's case, his legs. Upon first testing the item, Ichigo and Rukia leave it to its own devices while they go to fight a Hollow.

The mod soul, now free and having no desire to return to its pill form, goes on a mischievous and damaging (to Ichigo's reputation) rampage, diverting Ichigo from the pursuit of a particularly dangerous Hollow. The pair clash a few times during the course of the mod soul's spree, and would have continued had not the Hollow chosen to appear and attack a group of children nearby. The mod soul acts on its instincts, attacking the Hollow and giving Ichigo the time to defeat it.

Afterwards, Ichigo has a talk with the mod soul, who explains that he just wants to be free and experience life, similar to that of a real soul. Taking pity on him, Rukia and Ichigo ignore the standing directive to destroy all mod souls; they instead stick the mod soul into a lion plushie after failing to find a dead animal, or more specifically, a roadkill cat, giving it life. Ichigo gives the mod soul the name of Kon shortly thereafter, despite Kon's protests.

After this point, Ichigo uses Kon in the same manner as regular Soul Candy. When Uryū Ishida challenges Ichigo to a duel, the winner being decided by who could kill the most Hollows, Kon is given charge of Ichigo's body. He joins in the fight around Karakura to defeat Hollows, saving an ambushed Rukia. He later watches as Ichigo and Uryū team up to defeat a Menos Grande.

Soul Society arc
When Rukia decides to leave Karakura in order to protect Ichigo, Kon tries to stop her, but she ties him to the Kurosaki's toilet and gags him. When Ichigo, Orihime, Chad, and Uryū decide to go after Rukia, Kon tries to join them in Ichigo's body, but Ichigo makes him stay behind.

In the meantime, Kon is recruited by Don Kanonji as Karakura King in his Karakura Superheroes team. He serves as a soccer ball for Karin's special attack, the Karin Impact Kick.

Bount arc
After the beginning of the Bount Arc in the anime, Kon meets his fellow modified souls, Ririn, Kurōdo and Noba. He does not get along well with his new companions. Ririn views him as a fool and they often fight, and Kon is jealous of Kurōdo's assignment to guard Orihime. They do work together, however, most notably in episode 80, where they collaborate in the construction of several elaborate, yet useless, anti-doll traps.

When the Bounts infiltrate Soul Society, Kon joins Ichigo and the others to find them (partly due to fear of falling victim to Don Kanonji if he stayed behind in the real world again). Kon gets separated from the group in Rukongai and settles temporarily with a woman who owns a coffee shop. In contrast to Kon's usual lack of luck with women, this woman takes a shine to him. He eventually leaves to help fight the Bount, but continually arrives after the battles. After meeting up with everyone again (which is depicted during the non-sequitor previews for the next episodes), Kon brags about his stay with the woman, only to find out from Jūshirō Ukitake that it was actually a cross-dressing man.

Arrancar arc
With the Arrancar invasion beginning, Kon takes over Ichigo's body to have a little fun on the town, only to run into Grand Fisher. He is saved by the timely re-emergence of Isshin Kurosaki, Ichigo's father, as a Shinigami. Isshin quickly dispatches Grand Fisher with ease and Kon is forced to keep Isshin's true identity secret. Isshin reveals that he knew about Kon ever since meeting him during Grand Fisher's first attack at the graveyard.

Hueco Mundo arc
While Ichigo is off fighting in Hueco Mundo, Urahara makes Kon an offer to make him into a super hero to fight the Hollows in Karakura Town. Kon initially refuses, but jumps at the chance when Kisuke mentions he could become a 'babe magnet'. After the destruction of the Hollows fortress, Kon soon falls asleep as Urahara's plans are completed for the final showdown in Karakura Town.

Powers & Abilities
Enhanced Strength: During the few times that Kon is in combat, he has proven to be able to hold his own — in addition to possessing all the combat abilities of Ichigo's well-trained body, he was designed to have exceptionally powerful leg strength. He was able to fend Ichigo off in combat by using just kick-attacks and leg-blocks, and is able to kick aside massive Hollows. He is also capable of jumping over 13 meters and 56 cm from standing position in Ichigo's body.

Enhanced Speed: Despite his size in his plushie form, he can run 100 meters in 3.8 seconds while in it.

Spiritual Power: Being a modsoul, Kon does have some spiritual power, though definitely not as much as spiritually aware Humans, such as Yasutora Sado or Orihime Inoue.
