Kimura Kouichi

Evolution

 * Hybrid: Duskmon, Velgmon, Lowemon, Kaiser Leomon

Profile:
He was the twin brother of Kouji separated from Kouji when they were young when their parents divorced. For unknown reasons, neither twin was told of his brother's existence. Kouichi lived with just his mother and grandmother up until his grandmother's death. It has been indicated that his mother is often working, even though she is sick.

Just before her death, Kouichi's grandmother told him of Kouji. Kouichi tracked down his brother and speant an unknown period of time watching him from a distance, trying to get his courage up to speak with him. Kouichi's mindset grew gradually darker over this time, as he felt unable to tell anyone of his conflict. Finally, he got the chance when he saw Kouji on the train to Shibuya station, following Ophanimon's messege to the human world. Kouichi attempted to catch up with and talk to his brother, but missed the elevator. Attempting to catch up with Kouji, he ran down the stairs, tripped and apparantly died. Kouichi's next memory was of a dark expanse, possibly the borders of the Digital World, where he was tormented by memories of his family and the dark thoughts that had been invading his mind. Cherubimon appeared and gave him the Corrupted Human Spirit of Darkness, changing him into Duskmon.

Kouichi forgot who he was and served Cherubimon as one of his warriors, though his relationship with the other four was obviously strained. He speant most of his time inside the Venus Rose castle and was known for staring at the moons in a thoughtful manner. Mercuremon often spoke of him disdainfully because of this.

Eventually prodded into battle by Mercuremon, he first appeared to the other Legendary Chosen by killing and scanning Arbormon's data. During a battle, Duskmon badly injured Garmmon, forcing him to change back into Kouji. When he heard Kouji's name, he began to remember who he really was and became greatly bothered by it overwhelming everything in darkness.

When he returned to Cherubimon, confused, Cherubimon told him that his father had betrayed him and his mother and that he could take revenge on Kouji for this. Cherubimon then gave him the Corrupted Beast Spirit of Darkness, turning him into Velgmon. Losing himself in the darkness again, he was released on the other Children. Ophanimon, working through Kouji's D-Tector, managed to bring his memories back, but these were quickly twisted by Cherubimon. Velgmon, who was powerful enough to be a threat even to the Fusion Evolution Beowulfmon, seemed unstoppable. But working together, Takuya and Kouji managed to defeat him and took away the corrupted Spirits of Darkness.

Now back to his normal self, Kouichi was shy and ashamed for what he had done. When Cherubimon used an illusion of himself to attack the group, he offered Kouichi the chance to join him again, but Kouichi refused. It was then that the Spirits of Darkness were purified and returned to Kouichi, along with his D-Tector. The Human Spirit of Darkness changed him into Löwemon and the Beast Spirit of Darkness changed him into Kaiser Leomon.

Kouichi continued to travel with the other Legendary Chosen, but soon noticed that there was something strange about him. When the Royal Knights first attacked them, Kouichi was the only one of the Children who remained conscious. Even when they were blown to the Digital World's blue moon, he was the only one whose Digi Code never appeared, and he never seemed to become injured. During their battle at Akiba Market, Rhodo Knightmon told him that this was because he had no data to reveal. Kouichi was simply a spirit, pulled from his body, who was wandering the Digital World.

After hearing this, Kouichi became depressed, but made a point of not revealing this to the others, especially to Kouji. In the battle against Lucemon Falldown Mode in the Dark Area, Lowemon moved between the Light and Dark orbs of the Dead or Alive technique in order to save the other Children. Kouichi was scanned by Lucemon, but was able to give his Spirits to Kouji beforehand, enabling Kouji and Takuya to evolve into Susanoomon.

As the others were returning to the real world, Lowemon contacted Kouji through his D-Tector to tell him that Kouichi was still alive. The moment they returned, the others rushed to find him, but his body had already been moved from the stairs in Shibuya Station. They hurried to the hospital, where Kouichi was in critical condition - his heart had stopped, and the doctors were attempting to revive him. The power of the D-Tectors managed to revive Kouichi, who woke up because a tear of Kouji's that hit his cheek. When they returned to their lives, Kouichi introduced Kouji to their mother, and seems to be content.

=Trivia=
 * Kouichi is the only one of the Chosen Children that does not have a Beast Spirit Evolution sequence. Possibly to make up for this, his evolution sequence seems to be a mix between Human and Beast sequences.
 * Kouichi is the only Chosen Child in the animated Digimon series to 'die' in battle, although he is revived at the end of the season.
 * Originally, Crispin Freeman was considered to voice Kouji, but was reconsidered and was cast to play Kouichi instead.
