Taichi Yagami

Later, Izzy gives Tai a new pair of Goggles which allows Tai to see where distortions are so that they can pinpoint exactly where Digimon would realise in the Real World. As they use the Goggles to search, they come across Meiko, who was looking for her cat, and so they try to help her look, though are unable to find her cat and so split up. Realising they can get a better look at the whole City by using the Ferris Wheel, the DigiDestined get on it, though they trick Tai and Matt into being in one on their own so they can talk out their recent clash of ideals. They're unable to come to an agreement however, and Tai suddenly notices a large distortion and so the group run over to it and find Alphamon attacking Meicoomon and Meiko. The group fight Alphamon in their Champion forms (unaware of its strength due to Izzy's Digimon Analyser having no information on Alphamon) and are easily defeated, and after Greymon and Garurumon cause no damage in either Ultimate or Mega, they fuse together to form Omnimon and are finally able to fight Alphamon on an even keel. As Omnimon is about to blast Alphamon with a close range "Supreme Cannon", the fusion suddenly reverts because of Tai's worries, and the blast misses as Alphamon flees through a distortion. After the battle, Meiko reveals that she is a DigiDestined as well, and the group happily accept her and Meicoomon as the newest member of their team. Reunion (Adventure tri.)

Later, both Mimi, and a new student Meiko Mochizuki, transfer into Tai's school, and Meiko transfers into Tai's class. Joe finally joins the rest of the group as they discuss the situation. Tai and Matt clash over how to deal with the problem, and Matt storms off. After school Daigo reveals to Matt and Tai that he works for the government and explains that a distortion field had appeared between the Real World and the Digital World, and so Digimon had been using it as a gateway to get to the Real World. The government had been dealing with it so far, but as more and more powerful Digimon showed up, which he referred to as Infected Digimon, they needed the help of the DigiDestined. Later that night, Tai ponders if Matt was right and he was wrong, and Agumon tells Tai he believes in him to figure things out as Tai worries about the destruction they cause with their battles, worrying that he will one day be responsible for the death of a human. The next day Izzy invites the group over to his office, and Tai explains what he had learned from Daigo to the rest of the group. Izzy then reveals that he had created a cyberspace to allow their Digimon to transfer through devices such as laptops and phones to allow them to travel to and from Izzy's office when they need them for battle

As Tai and the Soccer team prepare for the match, Kuwagamon suddenly realises in the Real World and attacks Tai, and Tai ditches the team to chase it around the City on his bike. Kuwagamon continuously attacks Tai, causing large amounts of damage to the City and Tai realises that Kuwagamon is specifically targeting Tai. As Kuwagamon continues to cause more damage in its attempt to kill Tai, Tai becomes pissed off as he assumes that the good Digimon would get blamed. Tai tries to lead Kuwagamon away from the City to prevent any causalities, however Tai isn't able to get very far as Kuwagamon destroys his bike. Just as Kuwagamon is about to achieve its goal and murder Tai, Agumon suddenly appears and protects Tai, and after their delighted reunion, Agumon digivolves to Greymon and fights Kuwagamon. During their fight Greymon notes that Kuwagamon is stronger than when they last fought and as they continue to fight they suddenly go into a distortion in reality and are transported to the airport. As Tai tries to find Greymon, Kari rings him and tells him that Greymon and Kuwagamon were seen fighting at the airport, and as Tai makes his way there Daigo suddenly tells him to get into his car and drives him there. As Tai reaches the battle he sees that Greymon has been defeated by Kuwagamon, and Kuwagamon once again tries to murder Tai. Greymon uses the last of his strength to block the attack, saving Tai, and Greymon reverts back to Agumon. T.K., Sora, Matt, Izzy, Kari, and their Digimon arrive at the scene and join the battle - however things get worse when two more Kuwagamon arrive through distortions to fight the DigiDestined. The group (sans Agumon) all digivolve to Champion and are able to kill two of the Kuwagamon, however the third one defeats Garurumon and is killed by Alphamon, who's hand appears through a distortion, just as Kuwagamon is about to deal the killing blow to Garurumon. Mimi arrives after the battle and demands Tai pay for her flight, though admits.

Three years later in 2005, Tai is now a second year high school student.

As Kari wakes Tai up, Davis, Yolei, Cody, and Ken are defeated and captured by Alphamon. After waking up, Tai realises that he would be late for Soccer practice, and so rushes off without taking his lunch, though still takes his Digivice with him. After practice, Kari brings his lunch for him, and the rest of the Soccer team suddenly spring into action wanting to show off to Tai's sister. A few hours later during school, Tai's teacher, Daigo Nishijima, chastises him for being the only student to not turn in his list of future goals, and so is told to see Daigo in his office later in the day as Sora and Matt tell him off as well. As Tai eats his lunch, Matt invites him to his concert with his new band Knife of Day, with Tai finding the name hilarious. Tai however can't attend as he has a Soccer game at the same time. When Tai goes to Daigo's office, he steals Daigo's doughnut, and is only able to state that his goal is to see his faraway friend again (referring to Agumon, as the DigiPorts had permanently closed a year earlier), which Daigo misconstrues as Tai wanting to see a friend in a foreign Country and suggests Tai study another language to open up his avenues for the future. Tai then attempts to invite Izzy to his Soccer match, though Izzy is unable to due to having prior obligations with his family. This upsets Tai as he realises only Kari will be able to attend the match due to that, Matt's concert, and Joe's studying, and so Izzy jokingly invites Mimi to come and watch Tai's game, and to their surprise she agrees and books a flight, stating that Izzy and Tai will cover the price of her flight (which would cost over $1000). Things get even worse for Tai as Kari is unable to watch it either due to a friend's birthday party. Tai hides his feelings and pretends not to care that none of his friends would be at his game, though Kari easily sees through and this tries to call him out on it.

The warp leads back to the Real World. Tai returns home and relaxes for a bit while taking care of Kari, but he realizes that not only has little time passed but also that his friends haven't returned. Digimon then begin appear, though only he, Agumon, and his sister can see them. He receives a message from Izzy, who warns him not to come back to the Digital World, but Tai knows that he must go back to fix the balance. When Tai sees an Ogremon, Koromon digivolves into Agumon and a dimensional warp opens. Agumon knows he must return, and Tai, torn between his sister and his duty, tells Kari that he must go despite her pleas. He willingly enters the rift back to the Digital World. Home Away From Home.
Upon his re-entry, Tai finds the group in severe disarray. Time moves much quicker, and months have passed in the Digital World though only hours have in the Real World. The entire team has broken up, mainly to look for him, and are moving their separate ways. Tai first locates T.K., who has been left alone by the rest of the group, and manages to convince him to reconcile with his partner, Patamon, rather than be manipulated by DemiDevimon. Forget About It! With T.K. and their partners, Tai leads them to a diner, where they find Matt and Joe, rescuing them from Digitamamon. WereGarurumon's Diner He joins Joe in looking and finds Mimi, managing to convince her to leave her princess life with the Otamamon and Gekomon. Princess Karaoke.

Tai and Matt return to Primary Village in time to protect T.K. from a Black Gear-affected Leomon. They subsequently defeat Devimon and are told by Gennai to head to the Server Continent. The Legend of the DigiDestined Along the way, they find the Tags to their Crests but are attacked by Etemon on the Continent itself. The DigiDestined manage to escape into a tunnel, where Tai finds his Crest of Courage. The Dark Network of Etemon This discovery brings him arrogance, however, as well as the ambition to get Agumon to digivolve into Ultimate. His reckless measures get him into trouble by first overfeeding Agumon and then walking deliberately into trouble, knowing that danger is what causes their partners to digivolve. His actions cause Agumon to dark digivolve to SkullGreymon, who causes disaster by rampaging around and taking out Garurumon, Birdramon, and Kabuterimon before regressing into an exhausted Koromon. The Arrival of Skullgreymon As a result, both of them lose their confidence until Piximon arrives and forces them to face their doubts. Tai is reminded of the time when he tried to learn how to ride a bike and realizes that despite all the hardship, all of the pain, he needs to come back after suffering defeat. The Piximon Cometh

Returning to his cocky attitude, it is only bolstered when Izzy announces that they are in the Digital World, possibly leaving their bodies behind. Due to this, Tai throws caution to the wind and acts as reckless as he did before, believing that he can't really be harmed. Right before he walks through an electrified fence, Izzy snaps him out of it, telling him that dying in the Digital World still means real death and causing Tai to suddenly start becoming fearful. His hesitation costs him; Etemon attacks and prevents him from rescuing Sora and Biyomon, held captive by Datamon. The Prisoner of the Pyramid When the DigiDestined mount another assault on Etemon's base to rescue Sora, however, Tai learns to get over his fears, to walk for

Tai awakens to find Koromon sitting on him. Not remembering his previous encounter with Koromon, he freaks out but eventually comes to trust Koromon, and the two become friends and partners. After meeting up with Izzy, Tai goes up a tree to get their bearings but finds that he doesn't know where they are. Joining his fellow campers, each of whom have their own partners, they are attacked by Kuwagamon and their Digimon digivolve to Rookie, his Koromon to Agumon. Their efforts, however, result in them being thrown off a cliff, though Gomamon saves them. And so it begins... When Shellmon attacks as they rest at a beach, only Agumon's attacks work as he was the only one to eat, though he doesn't fare well. In order to help, Tai decides to provide a distraction and is caught while doing so. The rush of anger and protectiveness that Agumon feels spurs his Digivolution into the Champion form Greymon, who defeats Shellmon. The Birth of Greymon.

Tai continues to lead the group on their journey, getting into fights but generally blazing the trail. After the group gets separated by Devimon, Tai and Agumon manage to befriend Frigimon, who takes them to another island, where they find Matt and Gabumon. Tai gets into an argument with Matt about their next option; Matt wants to search for the others while Tai wants to head straight to Infinity Mountain. Their words come to blows, only broken up by Mojyamon. Subzero Ice Punch!

Tai is the oldest child of Susumu and Yuuko Kamiya. Much like the other Digidestined, he and his little sister, Kari, and pet cat Miko lived in Highton View Terrace. He and Kari receive a Digi-Egg, which eventually hatches into Botamon. Botamon digivolves quickly to Koromon, becoming their first experience with Digimon. Both Tai and Kari become friends with Koromon before he digivolves into BigAgumon and takes Kari on a ride, while Tai desperately follows. Agumon digivolves to RedGreymon to protect them from Parrotmon at Highton View Terrace, though he is beaten. Using Kari's whistle, Tai manages to revive RedGreymon long enough for both him and Parrotmon to destroy each other. Digimon Adventure This event leads to Tai, as well as Kari, being chosen as one of the DigiDestined, something they theorize once they return to the scene Return to Highton View Terrace, and confirmed by a separate entity who possesses Kari. The Ultimate Clash.

When Kari is four or five years old, she gets pneumonia, and Tai, not realizing the severity of her illness, takes her outside to play. His mother gets upset and slaps his face. Tai relives these painful memories when Kari gets sick once more while facing the Dark Masters. My Sister's Keeper.

When attending summer camp, it begins to snow. Tai, along with Matt, Sora, Izzy, Mimi Tachikawa, Joe Kido, and Takeru "T.K." Takaishi, find devices hurtling out of the sky, which they would later find to be called Digivices. All seven are then swept into the Digital World.

Tai is energetic and adventurous. He also acts impulsively and rushes without thinking the consequences, especially when his friends are in danger but is quick to realize and admit he has been wrong, and does whatever it takes to fix his mistakes. Despite his flaws, Tai is very caring and considerate of others, even if his actions may cause some people to think otherwise. It takes time for him to learn how to be a leader, but eventually he grows into the unifying force that leads all the other DigiDestined and keeps them together. As a teenager, Tai acts like the mellow and experienced mentor to the new Digidestined. He is less brash but still easygoing. He usually smirks.

Tai is very close to Kari and very protective of her, in part because of their past experiences. On her part, Kari idolizes Tai and confides in him even when they are older. Tai and Kari used to share a room, but sometime between Digimon Adventure and Digimon Adventure 02 Kari has moved to another room.

Tai's oldest friend is Sora Takenouchi, who has been in the same class as him since the first grade. In elementary school, they are both regulars in the soccer club. His closest friend is Koushiro "Izzy" Izumi, who he met at the soccer club. As the adventurous leader of the group, Tai is always the first to jump into action, though it often throws him into the path of danger. His ideas often conflict to the more rational and cautious Matt, which leads them to fight. Despite this, the two are close friends.

In Digimon Adventure tri., Tai's usual focus on the "big picture" leads him to become more cautious about battling after seeing the destruction caused by the Digimon's battles, and his resolve falters against the risk of collateral damage. When it becomes clear that Digimon like Alphamon will only cause more damage if they aren't stopped, Tai makes the decision to fight against them, but he still remains uneager to battle.

In Kizuna - responsible young adult with a ..𝗝𝗢𝗕 (boo).

His primary appearance has him wearing a medium blue short sleeved openly button shirt with a single left pocket, a white loose T-shirt underneath, black jeans and blue sneakers with white cross designs and white soles.
