Koichi Kimura

In the Digimon Frontier series, Koichi Kimura was the final member to join the team. He is chosen to wield the Spirits of Darkness that hold AncientSphinxmon's power. He is Koji's older twin brother. Their parents divorced when they were very young, so they hardly knew about each other. Koichi learns about Koji when his grandmother tells him on her deathbed. He runs after Koji, who is on his way to the Digital World, to try and catch up with him but he falls down a flight of stairs and ends up in a coma as a result. His mind is taken into the Digital World by Cherubimon, who can see his sadness. He erases Koichi's memories and gives him the Human Spirit of Darkness to give him a semi-physical form as Duskmon until he is freed from Cherubimon's control. After this, he wields the purified Spirits of Darkness and fights alongside his brother and their friends.

Kouichi was voiced by Kenichi Suzumura (Japan) & Crispin Freeman (US).

Digimon Forms (Tainted)
As Duskmon, Koichi has no memory of his past until he almost kills Koji during their first two confrontations. Hearing Koji's name being said over and over gives Duskmon great pain. After this, Duskmon fights Koji in order to learn the connection between them. Cherubimon gives him his Beast Spirit to become Velgemon but Ophanimon restores Koichi's memories, freeing him from his Spirits' control.
