The story of a headstrong Japanese Xiaolin Monk as well as the Xiaolin Dragon of Fire, Kimiko Tohomiko from Xiaolin Showdown and Xiaolin Chronicles.
Backstory
There is little information about Kimiko's early life, and her background varies between the original series and the reboot.
In Xiaolin Showdown, she is stated to have grown up in Tokyo, Japan and lives with her father Toshiro Tohomiko. Her mother is never mentioned or seen and her current whereabouts are unknown. Likewise, other members of her family are never mentioned or seen. As revealed in "The Return of PandaBubba", her father is the owner of Tohomiko Electronics, one of the world's largest video game developer and that makes Kimiko quite wealthy.
In Xiaolin Chronicles, she is stated to have grown up in Tokyo, Japan like in the original series and there’s no mention of having a mother. In addition to her father, she has an older sister named Tomoko Tohomiko. Likewise, other members of her family are never mentioned or seen. As revealed in "Tokyo Madness", her father is a scientist (at one point referred to as Dr. Toho) that works in virtual reality.
Kimiko’s relationship with her father is strained because Toshiro spent more time on his ‘secret’ project, neglecting her in the process. She does not have a better relationship with her older sister who was never around when Kimiko was growing up. However, in "Tigress Woo" the reason for Tomoko’s absence is explained as her being inter-dimensional spy under the alias Tigress Woo.
Xiaolin Showdown
Season 1
Kimiko made her first appearance in "The Journey of a Thousand Miles", the season one premiere as one of the new students that arrive at the Xiaolin Temple, whom Omi initially believes to be his students to preside over. However, thanks to her and the others' experiences, Omi is able to defeat Jack Spicer in his first showdown and win the Eye of Dashi. She is present when Master Fung formally introduces her and the others as the Dragons of Fire, Wind, and Earth respectively.
Her first major role in the season is "Tangled Web" where she loses her first showdown to Jack Spicer over the Monkey Staff, losing the Fist of Tebigong in the process. While her loss is attributed to Kimiko being hot-tempered, Omi specifically attributes it to her being a girl and proceeds to make sexist remarks about her capabilities. Fortunately, she is able to keep her temper in check and after learning to focus with the Tangle Web Comb, defeats Jack in the next showdown, winning the monks the Golden Tiger Claws.
Kimiko has a minimum presence for most of the first season. She and the other monks try cheering Raimundo up when he loses the Sword of the Storm to Tubbimura in "Shen Yi Bu" with no success. She is the first character to be transformed into sapphire by the Sapphire Dragon in "Night of the Sapphire Dragon", only to be freed at the end from a combination of Dojo’s fire breathing and hot sauce made by Clay’s grandfather.
Her second and final major role of the season is "Chameleon", when Jack Spicer kidnaps Kimiko after tricking her with a secret admirer letter. In her place, he uses his Chameleon-Bot to make a near-identical version of herself to infiltrate the Xiaolin Temple. The only one who seems to notice the difference is Omi and after Kimiko escapes Jack’s clutches, the two of them take down the Chameleon-Bot. However, victory is short-lived, as it turns out during the confusion, Jack Spicer stole most of the monks’ Shen Gong Wu and leaves them with just the Mantis Flip Coin.
She and Clay make a final stand in “Mala Mala Jong” against the titular character and because of this, she, Clay, and Omi are promoted to Xiaolin Apprentices, much to Raimundo’s frustration. Kimiko is present when Raimundo switches over to the Heylin side in "In the Flesh" and witness Wuya being resurrected.
Season 2
Following Wuya’s defeat in "Citadel of Doom", Kimiko for the most part has a minor role the second season. She and the other monks are captured by PandaBubba's henchmen in "Pandatown" but then are later freed by Dojo. Following Raimundo’s promotion to Xiaolin Apprentice at the end of the episode, the monks are able to learn a new move called the Dragon X-Kumei formation.
Kimiko and the other monks defeat Jack Spicer’s evil-dream team, which is made up of historical figures (along with his elementary math teacher) in "The Sands of Time". She manages to conquer her worst fear in "Dreamscape" and following the climatic showdown, the monks win both the Shadow of Fear and the Crouching Cougar. Although she claims she won't be easily charmed, Dyris manages to woo her during "Screams of the Siren" by insisting Kimiko's a lot beautiful than her.
Her first major role of the season is "The Evil Within" where she accidentally breaks the Mosaic Scale, which in return frees Sibini – an evil and mischievous spirit that had been sealed inside the Shen Gong Wu. Sibini proceeds to possess Clay and forms a brief partnership with Jack Spicer to find the Monarch Wings, a sister Shen Gong Wu.
Eventually, Sibini and Kimiko both touch the Monarch Wings at the same time, starting a Xiaolin Showdown. Kimiko wagers her Eye of Dashi against Sibini's Tangle Web Comb. The first one who can grab the Monarch Wings and leave the ring of geysers wins the showdown.
When the event starts, geysers shoot up into the air. Platforms of water are created in various directions that the competitors can stand on. Sibini grows to a larger form and begins jumping on the platforms, and Kimiko follows suit. Geysers start shooting water at Kimiko, and she is forced to dodge them. Sibini almost grabs the Monarch Wings, but a geyser surrounds the wings, blocking his attempt. The wings fly off toward Kimiko, and she reaches out to grab them. Sibini uses the Tangle Web Comb to ensnare her, and two geysers come straight for her. Kimiko uses the Eye of Dashi to break the comb's strands and escapes the geysers. As she escapes, Sibini jumps up and grabs the Monarch Wings. The Mosaic Scale floats out of Kimiko's pocket toward Sibini and merges with the Monarch Wings as Sibini jumps inside. Kimiko uses the Eye of Dashi and her fire element to trap Sibini inside the Shen Gong Wu, winning the showdown for her.
After Sibini's downfall at the hands of Kimiko and Omi (who acted upon the advice of Chase Young), Clay is free of the evil spirit's possession, though it’s revealed afterwards that he has no recollection of the events.
Her second and final major role of the season is "The Return of PandaBubba" where the monks travel to Tokyo, Japan and are introduced to her father, Toshiro Tohomiko. While getting to know a little about her background, the monks are gifted miniature robots that take on their appearances. Kimiko soon learns that her father has been deceived into working with PandaBubba, and that Jack has given him the Zing Zom-Bone.
Fueled with vengeance, Kimiko leads the monks back to the assembly room, where they elect to attack PandaBubba. Later, the Xiaolin Dragon of Fire and Pandabubba, hidden with the Shroud of Shadows, touch the Zing-Zom Bone at the same time, starting a Xiaolin Showdown. Kimiko wagers her Silk Spitter against Pandabubba's Shroud of Shadows, and the game is Goo Zombies 4.
When the event starts, Kimiko and Pandabubba are transported inside the video game, and Raimundo presses start to begin the showdown. The game is Goo Zombies 4, which Kimiko realizes she never beat Goo Zombies 3. Both competitors are given a cap, but Pandabubba throws his cap away when he says kid stuff. The first level is the zombie graveyard, and Kimiko is able to destroy them with her hat. Pandabubba uses the Shroud of Shadows to sneak up on the zombies and kill them, raising his score. Kimiko gets surrounded on all sides by zombies and uses her hat to get rid of them. At the end of the first level, Pandabubba is winning.
The second level is the haunted house, and Pandabubba gets a health boost at the beginning of it. Kimiko uses the Silk Spitter to kill some zombies, and runs away from many others, dropping the Silk Spitter in the process. Pandabubba picks it up and hides a zombie with the Shroud of Shadows. Kimiko tries to run from the invisible zombie but is trapped against a wall. She eventually sees the zombie's feet underneath and is able to kill him, taking the Shroud of Shadows.
The final level is the Monster Laboratory. Pandabubba tries to fight off the zombies, but gets swarmed, and becomes too weak to fight. Kimiko appears and takes the Silk Spitter back, heading to fight the final boss alone. Pandabubba warns her that her health is too low, but she goes in anyway. Kimiko uses the Shroud of Shadows to dodge the final boss, but he rips it off her. She tries to hit him with the Silk Spitter, but he dodges as well. The monsters shoot energy into red blocks next to Kimiko, which turns out to be power-ups. Kimiko uses them, and sends fire at the monster, defeating it and winning the showdown. Due to her victory, she foils PandaBubba's plans and saves her father and other workers from the corrupt executive's clutches.
Kimiko is present when a good chi-deprived Omi switches to the Heylin side for Chase Young in "Judging Omi" and with the help of Jack Spicer, returns his good chi in the following episode "Saving Omi". She gets her chi drained by the Chi Creature in "Finding Omi" though that is later restored by the efforts of Good Jack and Dojo. Following Chase’s defeat, all the monks are promoted to Wudai Warriors.
Season 3
In the third and final season Kimiko, plays a relatively small role. In "Bird of Paradise" she and the other monks unleash their new Wudai abilities, culminating with them performing Wudai Orion Formation. In the same episode, the Bird of Paradise reveals that her greatest quality is courage.
She is shown receiving presents from her father during the Chinese New Year at the beginning of "Omi Town" and then shown giving presents to Omi at the end, when he realizes the monks are his family. When the monks go on a quest to find their Wudai Weapons in "Treasure of the Blind Swordsman", Kimiko receives her Wudai Weapon, the Arrow Sparrow.
Her only major role of the season is "Hannibal's Revenge" where Kimiko first defeats the boys in a sparring match, much to Omi’s chagrin. She then reveals her secret: she had combined her PDA with several Shen Gong Wu to read the boys and later the world’s thoughts. Hannibal Roy Bean spies on her to acquire vital information on Chase Young. Kimiko then uses the Treasure of the Blind Swordsman to transform herself into Jack Spicer, defeating both Chase and Hannibal in a showdown by pitting them against each other.
At the beginning of the series finale "Time After Time: Part I", Kimiko and the other monks beat up Jack Spicer and bring mementos from the fight back to Master Fung, with hers being Jack’s left boot. When Omi travels into the future with Dojo, it is revealed that in his absence Jack Spicer had conquered the world. Kimiko had been chosen as the leader, the monks were thrown into prison and forced to fight well into their old age. In the attempt to restore the timeline, Kimiko along with Raimundo and Clay are presumably killed by Jack-Bots.
In "Time After Time: Part II", Omi tries to set things right, only to alter the future for a second time. Now Master Monk Guan has been turned evil and works along with Hannibal Roy Bean and Wuya. In this timeline, Clay has been chosen as the leader and the monks are farmers with Good Jack and a now good Chase Young. Once Hannibal Roy Bean has been defeated, the timeline is restored when Omi causes a paradox that resets everything. Kimiko is present when Raimundo as chosen as the leader and becomes the Shoku Warrior, congratulating him before everyone heads off into a final battle against the Heylin in the end.
Xiaolin Chronicles
Kimiko made her first appearance in "New Monk on the Block", the series premiere as she and the other monks have recently been promoted to Shoku Warrior. Although the monks are supposed to be unanimous when deciding a new student to teach, a dispute forms when selecting candidates Ping Pong and Willow, whom Omi favors the latter while everyone else had previously agreed to choose the former.
Although from the beginning she was hostile to Willow, in "A Girl Named Willow", Kimiko starts becoming suspicious of Willow’s motives as she keeps inquiring the boys (particularly Omi) about the location of the Shen Gong Wu vault. Her suspicious are confirmed in "The Fall of Xiaolin" when it’s revealed that Willow is Shadow, Chase Young's new partner. They proceed to steal all their Wu and easily defeat the monks along with Master Fung, destroying the Xiaolin Temple in the process.
Her first major role of the season is "Tokyo Madness" where a series of new reports about earthquakes in Japan prompt her to visit her father, Toshiro Tohomiko. Despite their strained relationship, Toshiro welcomes her warmly and showcases his secret project; a virtual recreation of Tokyo that people can live in. Unfortunately, Jack Spicer hacks the project and tries to destroy Virtual Tokyo with the Honey Badger and his computer virus. With the help from the other monks, Kimiko manages to defeat Jack and save her father’s project.
During the events of "Laws of Nature" Kimiko initiates a showdown against Shadow, only to lose in the conclusion. However, Shadow gives her the wagered Wu – the Taho Snout because it was important to join forces and track down Jack who is the cause of the episode’s chaotic setting. She is transformed into a jungle cat by Chase Young in "Princess Kaila of the Thousand Layer Mountain" though is later returned to normal after Omi defeats Chase in a showdown.
Following the arrival at their new temple, Kimiko and the other monks confront their worst fears in "Mi Temple, Mi Casa". After defeating Chase Young in a showdown, she is present when Ping Pong is formally promoted to Shoku Warrior. She gets her chi drained by the Chi Monster and turned into a zombie in "Rocco" though once again brought back to normal when Chase and Shadow are defeated in a showdown by Dojo and Rocco.
Her second major role of the season is "Tigress Woo" where her older sister, Tomoko Tohomiko suddenly appears on Kimiko’s birthday. While the others are amazed at her sister’s feats, Kimiko still feels upset about Tomoko never being there for her when growing up. Her trust in Tomoko is further complicated when it seems like Tomoko is working for Chase Young. But it turns out to be a ruse to gain his trust and Tomoko returns a stolen Shen Gong Wu from him to Kimiko as a birthday present.
Kimiko has a significant role during the season finale. In "The Call of the Dragon", she begins to have strange visions about a red dragon, though no one else believes her. Later on she gets a hunch that Dojo has been kidnapped by Chase and goes out to rescue him. While battling Chase, the red dragon appears and helps her get the upper hand momentarily.
In "The Mark of the Dragon Spirit", Kimiko meets Moonata, a former Xiaolin Dragon who informs her about the history of the Xiaolin Temple, as well as Chase’s past. She informs that Kimiko has chosen to become the first Xiaolin Dragon Rider of her generation, which will be crucial in defeating Chase, who has grown powerful. Despite Omi’s interference, Kimiko manages to summon a dragon – which turns out of the red dragon that’s been aiding her the whole time. Chase then appears to unleash destruction on the universe.
As Chase begins destroying the universe in "Fly the Dragon!", Kimiko confronts a jealous Omi and manages to reconcile with him. Moonata informs her that Omi is crucial in order to defeat Chase, the pair decide to team up. With the help of Tai Shui, the Cosmic Dragon, Chase Young is finally vanquished once and for all. Later, Kimiko is applauded for her actions by the other monks and Master Fung, with the red dragon being a new teammate which she named Zippy Lou.
