Oikawa Yukio

=Biographical information=

Profile
Oikawa is a tragic character, with many facets to his personality. In his core, he is very curious and intelligent, though extremely shy and lacking in self-esteem. He is easily obsessed with things he likes, such as the Digital World and his only friend, Hida Hiroki.

After getting possessed by Vamdemon, his personality became heavily influenced by the demonic entity possessing him. He became haughty, arrogant and cold, and more than a bit impatient and short-tempered.

Background
Born in the late 60's in Tokyo, Japan, the young Oikawa Yukio was a shy and lonely boy. His only friend in the world was Hida Hiroki, who was obsessed with the Digital World. The two would spent hours and hours playing video games and made contact with the Digital World. Hiroki and Yukio made a promise that one day they will visit the Digital World together.

Hida Chikara, Hiroki's father, became worried about his son's obsession and decided to take the video games away from them. Since Hiroki spent too much time with Yukio, Chikara tried to separate them and forbid Yukio from entering his house again. Although the two were heartbroken, they continued to remain friends.

When they entered collage, Hiroki and Yukio started work on a project that would help them get to the Digital World. Yukio became a computer programmer working along with Ichijouji Ken's father, while Hiroki became a police officer. In 1993, Hiroki got married a woman named Fumiko and had a child named Iori, though Yukio didn't have much contact with either. In 1995, following the battle between Parrotmon and Greymon in Hikarigaoka, Yukio went there to investigate along with Takeru's mother. At this point, Yukio hypothesized that it was the gateway to the Digital World.

In 1999, while on duty, Hiroki took a bullet for an important figure and died. Yukio took it very hard, and never got over the death of his only friend. On August 3rd, 1999, he was on the pier at Tokyo Bay, watching tearfully as the Digital World appeared in the sky; it is implied that he was going to commit suicide at the spot. However, before he could do anything, the disembodied spirit of Vamdemon offered to help him get to the Digital World. The desperate Yukio agreed, and Vamdemon entered his body, from then on acting as a latent force that directed Yukio's actions.

Digimon Adventure 02
In the following years, Oikawa created two half-human, half-Digimon creatures, Archnemon and Mummymon, who did his bidding. During the funeral of Osamu Ichijouji, he spotted Osamu's younger brother, Ken, and sensed that he was a Chosen Child. He proceeded to send Ken an anonymous email, directing him to the World of Darkness and corrupting him. He brought the technology for Evil Rings and Dark Towers from the World of Darkness and gave them to Ken, who became the Digimon Kaiser and used the technology to try and take over the Digital World. Oikawa had hoped that with Ken in control of the Digital World, he would have an easier time thinning the Digital World's defenses and getting in. However, the Chosen Children interfered.

When Ken shed off his Digimon Kaiser persona, Oikawa sent Archnemon and Mummymon to fight the Chosen Children and complete the task of thinning the Digital World's defenses. Their plan involved having Black War Greymon, an artificial Digimon Archnemon created using a hundred Dark Towers, destroying the seven Holy Stones that kept the balance of the Digital World in check. However, the Chosen Children managed to stop them, and Oikawa realized that he will have to adopt a more direct approach.

On Christmas, Oikawa spread Dark Towers across the Real World, and while the Chosen Children were busy taking them all down, he sent Archnemon and Mummymon in a truck to kidnap twenty children. The next day, they kidnapped Ken as well, and Oikawa scanned Ken's Dark Seed and spread it to the other children. They drove all the way to Hikarigaoka, where Demon stopped the truck, demanding to have Ken. As the Chosen Children fought Demon, Oikawa, Archnemon and Mummymon escaped, not before Oikawa told the Dark Seed children to come back to Hikarigaoka on December 31st.

The three hid away in a vacation house in the mountains, but Black War Greymon found them there, intending to kill Oikawa. He revealed to them that he had sensed Archnemon and Mummymon weren't fully Digimon, and that there was something less than human in Oikawa as well. However, they received some unexpected help from Yagami Taichi, Yagami Hikari and War Greymon, who were bent on keeping Oikawa alive to get answers from him. Oikawa, Archnemon and Mummymon took advantage of the opportunity and escaped back to Tokyo.

The next day, he came face to face with Hida Iori. Although he did not initially recognize the boy, he was shocked to see the name "Hida" on Iori's kendo equipment sack, and prevented Archnemon and Mummymon from attacking the boy after Iori confirmed that his father was Hida Hiroki. He spent much of that evening recalling his friendship with Hiroki and lamenting his past. However, there wasn't time for more of that, as he had received information that one of the seeded children will bloom prematurely. He located the child, Kawada Noriko, and absorbed the energy of her blooming Dark Seed, restoring some of Vamdemon's energy. Soon after this, Hida Chikara appeared and tried to talk to Oikawa's heart, apologizing for everything he had done and extending his hand in friendship. Oikawa was deeply moved and was intending to accept Chikara's friendship, but the spirit of Belial Vamdemon that resided inside him veered him from this and tried to harm Chikara with a huge burst of dark energy. Black War Greymon stepped before Chikara and took in the blast, saving the man from certain death.

On December 31st, Oikawa and the remaining seeded children met on the bridge in Hikarigaoka, and he used their power to open a gate to another world. However, it wasn't the Digital World, but rather a world of dreams. Vamdemon used its powers to speak to Oikawa and remind him of his manipulations, and came out of Oikawa's body to absorb the rest of the children's Dark Seeds. Drained of his energy, Oikawa fell to the ground, unconscious.

Vamdemon used the power of the Dark Seeds to become Belial Vamdemon, killed Archnemon and Mummymon, subjected the Chosen Children to illusions, escaped to the Digital World, spread darkness across the Real World and used the seeded children's despair to get energy, but all this didn't help him and the Chosen Children of the world destroyed him. Following Belial Vamdemon's defeat, Iori went back to the world of dreams to help the fallen Oikawa, dragging him to the edge of the tear between the two worlds. This way, he gave Oikawa a chance to talk to Pipimon, his long-lost partner. However, Oikawa was close to death, and didn't have much time left. To atone for his deeds and help the world he loved so much, Oikawa 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.
