Ken Ichijouji (一乗寺 賢 Ichijōji Ken?) is a fictional character in the Digimon Adventure 02 anime series. Ken is the final member of the 02 DigiDestined, partnered with Wormmon, and is the holder of the Crest of Kindness. Unlike the other 02 DigiDestined, he lives in Tamachi.

Formerly introduced as the devious Digimon Emperor (デジモンカイザー Dejimon Kaizā?, lit. "Digimon Kaiser"[2]), Ken works hard to try and atone for his wicked acts and eventually is helped along the way by Davis Motomiya and the others.


Before 2000, Ken is a very small boy with pale skin, messy dark blue hair and blue eyes. He wears a pink short-sleeved button-up shirt, grey shorts and white socks.

In 2000, Ken is slightly taller, and his hair is less messy. He wears a pink T-shirt with a blue collar and sleeve ends, brown shorts, white socks, and turquoise shoes with white soles. The Crest of Kindness

In 2001, Ken's hair is tidier and combed to the right. He is shown wearing the summer version of the Tamachi Elementary School uniform: a white short-sleeved button-up shirt with the school symbol on the left breast tucked into grey pants, with black shoes.

In 2002, Ken's hair is straight and rather long, reaching his chin in the front and slightly shorter in the back. He is usually seen wearing Tamachi Elementary School's uniform: a grey gakuran-style jacket with the school symbol on the collar, grey pants and black shoes. A New Digitude He is sometimes seen without the jacket, wearing a white button-up shirt with long sleeves and the Tamachi Elementary School symbol on the left breast. Genesis of Evil

As the Digimon Emperor, Ken sports spiky hair in varying shades of blue and light blue, which looks very similar to Sam's. He wears yellow sunglasses with purple lenses, a blue, gray and white jumpsuit, black shoes, cuffs on his wrists and ankles, a dark gray belt with a yellow buckle on it, and also a blue cape with a yellow lining that looks very much like insect wings, with golden-yellow shoulder pads. Enter Flamedramon

During winter, he wears a warm sweater with a dark blue top, and a light blue bottom, and a purple lozenges pattern in the middle. He also wears a light green button-up shirt, white pants, black socks, and red shoes with black laces and grey soles. A Very Digi-Christmas Outside, he wears a white scarf. While in Mexico, he doesn't wear his sweater and his shirt sleeves are rolled back. Digimon World Tour, Pt. 3

At the time of Digimon Adventure tri. which is in 2005, Ken was 14 years old when he along with Davis, Yolei and Cody are defeated by Alphamon. In silhouette when Ken was defeated by Alphamon, he retains the same look he had in Digimon Adventure 02. Reunion

In 2010, Ken is 19 years old and his hair is neatly cut short and the fringes are now on the right side. He now wears a black short sleeved polo shirt, blue jeans with light blue folded sleeves and a pair of shades of brown short boots.

In 2028, Ken is an adult, and his hair is longer and parted in the middle. He wears a grey shirt with a high collar over a black turtleneck sweater and grey pants. While working, he wears an open grey suit jacket over a light purple, grey pants with a black belt, a brown gun holster, and a light grey trenchcoat. A Million Points of Light


Ken, in his core, is a sweet and kind person. He is polite and courteous towards others, and has a gentle spirit. However, he is haunted by the death of his older brother, Sam, and later by his actions as the Digimon Emperor. His guilt and his desire to make sure no one else suffers because of him causes him to be self-sacrificing and believe he doesn't deserve happiness. As the DigiDestined, primarily Davis Motomiya, welcome him into their group, he opens up and begins to smile more. Ken has a blunt and sassy side to him, which he only shows with people he is comfortable with like his mother and Davis.

As the Digimon Emperor, Ken is cold, cruel and sadistic, enjoying nothing more than causing pain to Digimon and making them suffer for his amusement. He also acquired a very superficial concept of things, believing that 'big is strong and small is weak' and judging only appearances, which is why he didn't even bother to digivolve Wormmon, considering him weak and insignificant. This persona was fueled by the Dark Spore embedded in his neck, which corrupted him when it was activated in the Dark Ocean.

Ken is very intelligent and athletic. Under the Dark Spore's influence, he became a top-level computer programmer and soccer player, and also excelled in activities like chess and judo. Even without said influence, Ken has good grades and is better at soccer than a talented player like Davis. Ken knows how to speak some Spanish, allowing him to communicate easily with Rosa in Mexico. Digimon World Tour, Pt. 3

Ken is notable among the main 02 DigiDestined for being the only "new" member in that generation to own an original Digivice that later turned into a D-3, as well as the only one to have a crest of his own. Because of this, it is somewhat implied Ken was intended to be a DigiDestined similar to the original eight.


Ken Ichijouji (一乗寺 賢)

Name used in the Japanese version of Digimon Adventure 02 and related materials. Also used in multiple dubs, including the American English.

  • Ichijouji (一乗寺?). Japanese surname that means "first temple".
  • Ken (?). Masculine Japanese name that means "intelligent". This is a reference to Ken's intelligence.


Digimon Adventure 02

As a young boy, Ken felt ignored by his parents in favor of his older brother Sam Ichijouji, who was a child prodigy. At times, Ken got along very well his brother and even showed admiration for him, especially when they went out to the balcony to blow bubbles together. However, because of everyone's attention being focused on Sam, he also finds himself jealous of his older brother, sometimes wishing that he was an only child.

One day while with Sam in his room, a Digivice came out of Sam's computer. It was meant for Ken, but neither of them knew this, so Sam picked it up and put it in his drawer, telling Ken not to touch the drawer until he could figure out what it is. When Sam left the room, Ken, in childish curiosity, touched the Digivice and was pulled through Sam's computer into the Digital World. There, he met his Digimon partner, Wormmon, and helped Ryo Akiyama in fighting Millenniummon. However, when Millenniummon was defeated, he forced out pieces of his data in the form of Dark Spores. Ken pushed Ryo out of the way of the incoming Spores, and one of them embedded itself in the back of his neck. Wormmon and Ryo tended to Ken for three weeks until he was well enough to return to the Real World, where he found that it's the same day as he had left; this is likely due to Millenniummon's ability to warp time and space. When Sam came back into his room and found Ken holding the Digivice, he scathingly berated Ken for breaking his trust and proceeded to kick Ken out of the room. As a result, Ken again found himself wishing that Sam "would just disappear".

Tragically, Sam died after being hit by a car shortly after that day. Ken was devastated following the accident, suffering from strong feelings of guilt because he felt that he'd somehow caused Sam's death by his "wish".

Some time later, an email from a mysterious figure (later revealed to be Yukio Oikawa) told him to use the Digivice to escape the guilt and sadness over Sam's death. Ken did this and was transported to the Dark Ocean. There, Ken dipped his Digivice in the ocean, turning it into a dark D-3. Doing so caused the Dark Spore to activate, and Ken began believing that the Digital World is a place for him to shape and command as his own. From there, Ken adopted several aspects of Sam and very rapidly developed into a child prodigy, excelling perfectly at virtually everything that he chooses to pursue, whether it's an intellectual activity or an athletic one, such as chess or judo. He even became the star player of the Tamachi Soccer team, where he broke the record for scoring most goals in a league season with 45. However, as the Dark Spore developed and continued to influence him, Ken became heartless towards society, viewing everyone around him as pathetic insects beneath his notice. It's then that he set his sights on the world which could challenge him, a world that he felt it's his destiny to control: the Digital World.

Ken returns to the Digital World and, through the subtle, unseen manipulations of Arukenimon, assumes the guise of the Digimon Emperor and begins to take over using Dark Rings to enslave Digimon, similar to the Black Gears Devimon used on the Digimon of File Island. The Dark Rings gives each Digimon glowing red eyes and make those up to and including a certain level completely obedient. Ken often uses these as sport, such as having two of them fight in a Colosseum-style arena, and keeps them locked in a sophisticated system of cages.

As the Digimon Emperor, Ken has many conflicts with the new DigiDestined as he plans to bring a new order to the Digital World. Ken's dark Digivice prevents the Digimon from being able to naturally digivolve, but Davis Motomiya, Cody Hida and Yolei Inoue's Digimon are able to use Armor Digivolution to free his Dark Ring-enslaved Digimon. During one battle, they discover that the Control Spires allow the Dark Rings to work and also begin destroying them as well. Enter Flamedramon A New Digitude Iron Vegiemon

The new DigiDestined become aware of Ken as they watch a newscast about how he wins a National Computer Programming Contest (the dub states he wins by making a machine that can brush people's teeth for them). The news also mentions many of Ken's previous accomplishments, as well as shows an interview with his proud parents. A New Digitude Sometime later, Tamachi Elementary School's soccer team, Tamachi FC plays a match against Odaiba Elementary School's team. Though Ken only arrived for the second half, he recognizes the DigiDestined in the bleachers, and Davis on the team. Though he is annoyed by their presence, he keeps up the appearance of a well-mannered genius, even when Davis injures Ken's ankle in an attempt to block him from scoring a goal. While he continues to put on a polite facade and compliments Davis on his power, he retaliates as the Digimon Emperor by threatening to feed the other DigiDestined to Deltamon unless Davis degrades himself. However, the real DigiDestined soon appear, revealing that the Emperor deceived Davis. Ken vows to take over the world, but Davis tackles him in a scuffle. During the fight, Davis recognizes a familiar injury on the Emperor's leg. Defeated, Ken reveals that he is the Digimon Emperor and flies off. Ken's Secret

With his identity revealed and his patience for humanity at an end, Ken abandons the Real World to live in the Digital World and assumes the Emperor identity permanently. During that time, he creates Dark Spirals to control Ultimate Level Digimon as well as some Champion Level Digimon like Tai's Greymon, who Ken first digivolves into a berserk SkullGreymon and then into a controllable MetalGreymon (Virus) through the Dark Spiral. His parents, with no knowledge of where he has gone, panic and make various televised pleas to try and search for Ken, but with no success. The Emperor's New Home The Captive Digimon Storm Of Friendship He also works on a special project, using data he collected from various Digimon to make his ultimate creation: Kimeramon. An Old Enemy Returns

However, Kimeramon proves to be uncontrollable, though Ken denies this is the case. Eventually, the DigiDestined manage to down Ken's flying base, and Kimeramon is destroyed by Magnamon with the aid of Ken's own partner, Wormmon. Ken refuses to believe that he lost and proclaims he would "reset" the Digital World, thinking it's just a computer program or a video game that could be rewritten. When the DigiDestined explain to him that it's a real place and that Digimon are living creatures, Ken, realizing the merciless cruelty he inflicted upon innocent lives, sheds the Digimon Emperor persona and collapses to his knees from the horror. He gets a chance to hold Wormmon in his arms before the Digimon dies from expanding his power, causing Ken to remember and relive the grief he experienced after his brother's death. Guilt ridden, Ken tearfully staggers off back to the Real World. By the time he returns home, he had been missing for several months. The Crest of Kindness

Ken sleeps for days, in a type of coma, where memories of his brother, the Digivice and his first trip to the Digital World randomly surface in his mind. When he wakes, he develops amnesia and cannot recognize his parents. In a dazed state, he later travels to the Digital World and wanders aimlessly before finding himself in Primary Village. There, he is forced to remember his malicious actions by the baby Digimon, who angrily recall the abuse he'd inflicted. After crying out apologies in hysterics, realizing how truly sorry he is, Ken is reunited with Leafmon, the baby form of Wormmon reborn. He returns home, finally realizing he has those who love him and that he has a chance to set things right. Genesis of Evil

After that, Ken vows to atone for the horrible deeds he committed as the Emperor. As he does, he learns that he was used by Arukenimon when she takes all data relating to the Control Spires from the boy's computer. With Stingmon, Wormmon's Champion form, he begins the daunting task of destroying the Control Spires that he erected. At first, upon learning that Ken is back and doing good, Davis wants to ask Ken to join the team, but none of the other DigiDestined approve the idea, particularly Cody. They are convinced that he is still evil when Ken saves Cody's life by ordering Stingmon to destroy Thundermon in Primary Village. The DigiDestined believe that Thundermon is a real Digimon, but he is actually created from a Control Spire. Once the DigiDestined learn that in the next battle, they become more understanding. If I had a Tail Hammer Spirit Needle

When Ken finds out his fallen base is in danger of exploding, he and Stingmon arrive and try to stop it alone. However, Davis and ExVeemon refuse to let them sacrifice themselves, and their words of friendship resonate with Ken and Stingmon's hearts. Through this understanding, ExVeemon and Stingmon DNA Digivolve to form Paildramon. United We Stand

After this, Ken becomes a member of the team, but despite joining them, he feels uncomfortable around the others. He is particularly uncomfortable around Cody, who still strongly dislikes him for what he did in the past. Ultimate Anti-Hero However, he still takes part in clean up jobs and other tasks with the other DigiDestined, as well as helps out in all the battles against Arukenimon, Mummymon and BlackWarGreymon. Slowly over time, he begins to integrate with the group and everyone, even Cody, becomes increasingly more accepting of his presence.

Ken's place on the team is unconditionally cemented when he holds a Christmas party and invites everyone over to his home. There, he is able to truly smile and laugh for the first time in a long while. A Very Digi-Christmas On Christmas Day, as Control Spires and wild Digimon appear in the Real World, Ken is stuck in Tamachi when a Triceramon attacks, but Davis and Veemon arrive to help. During the fight, Paildramon receives the power to evolve to Imperialdramon. Davis and Ken ride on Imperialdramon to destroy Control Spires across Japan, before returning to Odaiba to pick up the other DigiDestined. Dramon Power Afterwards, Ken and Wormmon go to Mexico City with Yamato "Matt" Ishida and Gabumon to help a Mexican DigiDestined, Rosa and her partner Gotsumon transport some loose Digimon back to the Digital World. Digimon World Tour, Pt. 3

That night, when Ken gets home, he has a dream of his first time in the Digital World and the Dark Spore. The next day, Daemon and his Daemon Corps begin to appeared in Tokyo, and wreaks havoc while seeking Ken and the Dark Spore. But Arukenimon manages to convince Ken to come with her, using the children she "kidnapped" to motivate him. Once inside the truck, Ken is confronted by Yukio Oikawa, whom he had met at his brother's funeral a few years back. Oikawa reveals the nature of Dark Spore and copies its data into the other children, who had all been taken willingly. Oikawa attempts to hand Ken over to Daemon at Highton View Terrace, but the DigiDestined intervene. When they realize Daemon is too powerful an opponent, Ken uses his dark D-3 to open a gate to the Dark Ocean with the help of the other DigiDestined. After this, Ken finally introduces his stunned parents to Wormmon. The following day, now aware of what was going on, Ken's father is happy to help the children look for Oikawa.

During the battle against MaloMyotismon, Ken is paralyzed with fear after witnessing MaloMyotismon's cruelty. While he is subjected to MaloMyotismon's illusion, he witnesses his desire to see himself punished by every Digimon he enslaved for what he did as the Digimon Emperor. When the illusory version of him is deleted, he witnesses an illusionary version of his brother, alive and well. Ken's final epiphany occurs when the illusory Sam tells Ken that he can't change the past but can ensure a bright future for himself. Following his brother's final words and angry at having been manipulated yet again, Ken releases his guilt, crying out that he isn't the Digimon Emperor any more, he is through with punishing himself and paid enough for his crimes. With that, his friends break through to him, encouraging him to break through the illusion and rejoin the final battle against MaloMyotismon. He then helps defeat MaloMyotismon once and for all with the light of his Digivice. Oikawa's Shame The Last Temptation of the DigiDestined A Million Points of Light

On Valentine's Day 2003, when Davis tries to assume the "Emperor" look, Ken tries to talk him out of it in vain. Ken manages to obtain the Digi-Egg of Kindness and armor digivolves Wormmon to Bucchiemon to stop Davis from reluctantly beating Veemon to get into character. Armor Evolution to the Unknown

On Spring 2003, Ken reminisces about his brother, the mistakes of his past, and how happy and thankful he is now. Digimon Adventure 02 Original Story: 2003 -Spring-

Later, Himekawa reveals that she is in possession of Ken's D3 Digivice and D-Terminal, which are used by the Digidestined to enter the Digital World after it is rebooted. It is later revealed that the Digimon Emperor was not Ken, but Gennai using Ken's old Digimon Emperor persona as an avatar. Confession

Then the Mysterious Man appears, turns off the 02 DigiDestined's life support and states that they can save them by sending them back to the human world but that should they do so, the lab will explode and that only one pod remains, meaning only one of them can go along with the rest of them.
