Yukio Oikawa

Yukio Oikawa is a character in the anime series Digimon.

Oikawa is considered by many to be the most tragic character in the series. He is one of the few human adults to have a knowledge of the Digital World. He was born in 1969. As a kid, he was an extreme loner; mocked and shunned by classmates, he had no friends. A boy named Hiroki Hida was the only one who never treated him like dirt and became his only friend; Hiroki was born in the same year as Oikawa.

Hida had this obessesion: he could communicate with the Digital World through old video games and he shared the same obessession with Oikawa. They both ended up communicating with the Digital World. They spent hours and hours on the video games talking with the Digital World.

Hiroki's father, Chikara, became very worried about the obsession his son had so he decided that Hiroki and Oikawa were being too childish. Chikara forbid his son from playing video games and tried to separate Hiroki from Oikawa, fearing that they were spending too much time together. The two were heartborken but they remained friends; they made the promise to each other that, one day, these two would go to the Digital World and they started sharing their dreams and never told anyone else about it. Oikawa worked with Ken Ichijouji's father as a computer programmer.

In 1995, when the Hikarigota incident occurred, Oikawa went to investigate worked along with Natsuko (Nancy) Takaishi. There, Oikawa learned that Hikarigota served as a gateway to the Digital World. Four years later, on August 3, 1999, Oikawa visited the grave of the recently dead Hiroki, angry that Hiroki "broke" his promise. Oikawa then saw the Chosen Children (DigiDestined) in the sky as they leave Odaiba. Seeing his dream realized, Oikawa was soon possessed by the disembodied spirit of Vandemon (Myotismon) after it promised to make his wish to go their come true. He wasn't consciously aware of the spirit but it have him knowledge enough to create two Digimon to serve him. They were Archnemon (Arukenimon) and Mummymon. While they could travel to the Digital World he still could not. He knew he would have to weaken the boundaries between them to accomplish this. He manipulated Ken Ichijouji into becoming the Digimon Kaiser (Digimon Emperor). As the Digimon Kaiser he constructed Dark Towers (Control Spires) which began to weaken the boundaries. But when the Chosen Children defeated the Digimon Kaiser and began demolishing the towers he knew he would have to take action. He sent Archnemon and Mummymon to battle against the Chosen Children many times. Later he decided it would be easier to weaken the barrier from his own side. He captured Ken and copied the Dark Seed (Dark Spore) that was inside him and placed the copy into several other children, such as Noriko. This led to some conflict with Demon (Daemon) whom also sook out the Dark Seed inside Ken. But once he copied it he no longer needed Ken and handed him over, though the other Chosen Children showed up and rescued him during the hand over.

As he waited for the Dark Seeds to grow stronger one of Archnemon's creation, Blackwargreymon, interrupted his rest. He blamed him for his flawed creation. Blackwargreymon then said he was going to put an end to them. Though he received unlikely help from the Chosen Children, though only because they knew they might need him to take the Dark Spores out. As Blackwargreymon fought against the Chosen Children he fled with Archnemon and Mummymon.

But later he again confronted both the Chosen Children and Blackwargreymon, now working together. Unexpectedly Chikara happened apun the at this very minute. Seeing the one whom separated him from the Digital World again caused the spirit of Vandemon to flare up and he struck at him with some sort of dark power. Blackwargreymon intercepted the attack and was fatally injured. While everyone was shocked from this Archnemon and Mummymon pulled Oikawa away from the scene.

After the Dark Seeds had grown strong enough he gathered all of the children together and used the Dark Seeds to try and open a gate to the Digital World. But unbeknownst to him Blackwargreymon had sealed the passage way to the Digital World with the last of his power. Instead to opened up a portal to an entirely different world. Some of the Chosen Children showed up at the last second and made it through the portal to that world as well. It was a confusing world that looked entirely random and had no since of direction.

Oikawa suddenly fell to his knees in pain and the spirit of Vandemon left him. It absorbed the Dark Seeds of the children and transformed itself into Belialvamdemon (Malomyotismon). The spirit leaving Oikawa left him fatally injured but he was able to witness the final battle between all of the Chosen Children from around the world against Belialvamdemon. After the battle was over he met the Digimon he had seen so long ago in the video game, Datirimon, who said he was Oikawa's partner Digimon. He apologized to the Chosen Children for what he had done before passing away. His spirit went on to live in the Digital World.
