Hida Iori

Digimon Adventure
In 1999, Iori's father, a police officer named Hiroki, took a bullet for an important figure and died. This had a great effect on the young boy, who was just six years old at the time.

On August 3rd of the same year, Iori and his mother and grandfather were passengers on a plane that took flight shortly after the Digital World appeared in the sky and froze. The plane were saved from crashing by Kabuterimon and Garudamon. He did not know it then, but it was then when Iori was chosen to fight for the Digital World in the future.

Between Digimon Adventure and Digimon Adventure 02
Around 2001, the Hida family moved to a new building in Odaiba, where Iori met and befriended Inoue Miyako, a spunky girl three years his senior.

Digimon Adventure 02
In 2002, on the first day of school, Iori and Miyako met Takaishi Takeru, their new neighbor. On the same day, they received D-3s, along with a boy named Motomiya Daisuke, and found out that they were Chosen Children, much like Takeru and his old friend Yagami Hikari. On the next day, Iori traveled with the others to the Digital World, where he received his partner, Armadimon, as well as the Digimental of Knowledge. With his fellow Chosen Children, he started fighting to free the Digital World from the clutches of the Digimon Kaiser.

On one occasion, when the team followed a signal indicated a nearby Digimental, Iori ran ahead of everyone as he assumed it was his, for Daisuke and Miyako already had their second Digimentals. They became trapped in an offshore oil platform by an Evil Ringed Mega Seadramon without much oxygen left, and Iori blamed himself. The other children sent him off in a one-man escape pod to call Jou for help. Jou was taking an exam at cram school, so Iori had to lie about the health of Jou's father to get him out. When they got to the oil platform, they found out that the Digimental of Sincerity was there, but Iori refused to take it because he lied, and was thus insincere, and was also untrustworthy because he put his friends in danger. However, Jou convinced him that he was worthy of receiving the Digimental of Sincerity, and Iori thus managed to activate the Digimental and evolve Armadimon to Submarimon, to help defeat Mega Seadramon.

After the Digimon Kaiser was defeated and became Ken again, Iori still couldn't forgive him for what he had done and had a hard time accepting him into the team. At one point, it put the entire team at risk when BlackWarGreymon appeared. Iori's attitude towards Ken softened the more Ken was integrated into the team.

After Paildramon and Silphymon debuted, Iori realized that Takeru would be his Jogress partner eventually. Iori then noticed that Takeru had been acting oddly violent and angry when BlackWarGreymon was involved, and realized that he had acted the same way about Chimeramon, the Digimon Kaiser after he had unleashed the synthetic Digimon. Desperate to understand Takeru's attitude towards evil, he turned to Takeru's older brother, Yamato, who told him about the battle between Angemon and Devimon and about Angemon's subsequent death, which had affected him more than anyone had realized. This was all Iori needed for Ankylomon and Angemon to Jogress into Shakkoumon.

In December, Iori accepted an invitation to Ken's Christmas party, and came with all the other younger Chosen. Their party ended abruptly as they had to send rampaging Digimon back to the Digital World and destroy a Dark Tower. On Christmas Day, the Chosen Children found out that Digital Gates were open in the entire world, and he went to Australia with Jou and their Digimon to help the Digidestined of the Pacific to round up the wild Digimon that had come through the gates.

Back in Japan, the children had to fend off the Demon Corps, a group of evil Digimon led by Demon, as well as Archnemon, Mummymon and their boss, the human Oikawa Yukio. He had to face reality as MarineDevimon of the Demon Corps was about to destroy a hospital where he and Takeru were trying to help a disabled girl get to safety. Shakkoumon's only option was to destroy MarineDevimon, shocking and upsetting Iori, though he had to accept that it had to be done. Afterwards, he and the other children helped Ken open a gate to the World of Darkness and banished Demon through the gate.

Several days later, his grandfather, Chikara, had finally noticed the presence of Armadimon in the house. Iori was shocked to learn that his father had known of the Digital World and contacted it when he was just a little boy. That afternoon, he came face to face with Oikawa, who acted oddly and retreated when he found out Iori's family name was Hida. The next day, in a confrontation with Oikawa, Chikara revealed that Oikawa was Hida Hiroki's best friend for many years.

In the world of dreams, it was revealed that Oikawa Yukio was possessed by the spirit of BelialVamdemon, who absorbed the power of the Dark Seeds he sowed in the necks of twenty children to gain a corporeal form. He killed Archnemon and Mummymon, which shocked and frightened Iori and the others. When Daisuke and XV-mon started fighting back, BelialVamdemon subjected the children to an illusion, showing their greatest desire. Iori's desire was to be with his father and show him the Digital World, but it was broken by Armadimon's explanation that it wasn't real, and Fladramon appeared to take him back to the other kids. When everyone's illusions were broken, Iori used the power of the dream dimension against BelialVamdemon, with Ankylomon, Digmon, Submarimon and Shakkoumon appearing all at once to fight BelialVamdemon. After BelialVamdemon escaped to the Digital World, the light from his D-3 helped weaken BelialVamdemon and power up Imperialdramon Fighter Mode's Giga Death cannon.

Immediately after BelialVamdemon was destroyed, Iori went back to the dream dimension to help the fallen Oikawa, dragging him to the edge of the tear between the two worlds. However, Oikawa, close to death, used the other world to fulfill a dream of his own. With that, Oikawa's body was deleted and the digital particles transformed into a host of butterflies, which spread across the Digital World, restoring peace and beauty to it.

Diablomon Strikes Back
Iori was sent with Takeru to collect Kuramon that Diablomon sent to Earth. They parted when it was decided that Takeru will go into the Internet to help defeat Diablomon, and made his way to the Rainbow Bridge to meet up with Miyako. There, he watched as all of the Kuramon fused into Armagemon, and the following battle. When Armagemon separated into hundreds of Kuramon again, it was Iori's notion for everyone to use their Digivices and cellphones to capture the Kuramon that saved the say.

25 Years Later
By 2027, Iori has become a high-class defense attorney. He is married and has a daughter, who is the partner of an Upamon.
