Koji Minamoto (輝二 (コウジ) Minamoto Kouji?) is a main character in the Digimon anime series Digimon Frontier. He is one of the "DigiDestined", children who were chosen to receive the ability to transform into Digimon in order to save the Digital World.


Koji is a preteen boy with pale skin, shoulder-length black hair which is tied in a low ponytail, and dark blue eyes. He wears a blue jacket with yellow stripes on the sleeves over a yellow T-shirt with a blue neckline and sleeve trimmings, grey pants that end at his ankles, long blue socks, and white sneakers with blue stripes. On his head, he wears a blue bandana with dark grey stripes. His face is identical to his twin brother, Koichi.


Koji is a quiet boy who prefers to keep to himself. He starts off rather standoffish and doesn't think much of the abilities of others, but in truth, he is a shy and lonely boy who isn't sure how to approach others.

Name used in the American English dub of Digimon Frontier and related materials. Given name romanized by Bandai Japan in LB Pop-Up Theater Digimon Frontier.


Koji was the child chosen to wield the Spirits of Light. Koji starts the series as the group loner, but gradually warms up to the others. Koji receives Ophanimon's cell phone message while he was out buying flowers for his stepmother. He followed the instructions on the SMS, which led him to a subway station where a Trailmon took him to the Digital World.

Koji traveled alone until he met Tommy Himi and J.P. Shibayama and had to save the two from a horde of attacking Pagumon. From then on, Koji showed up to help the other DigiDestined from time to time, and then eventually joins the group permanently.

Koji also meets his twin brother, Koichi Kimura, for the first time in the Digital World. Koji's parents had split up when they were too young to remember each other, and his mother had moved out with Koichi and their grandmother. Koji's father remarried, but lied to Koji, telling him that his mother had died, and never informed him of his twin brother. As such, Koji grew up never knowing he had a brother, let alone a twin. But he missed his birth mother very much (not knowing that she was actually still alive) and he would constantly look at a photograph of her that was on the backside of a framed picture containing his current family, something his father seemed to disapprove of. Despite his stepmother's kindness and the fact she genuinely cares about him, he had a really difficult relationship with her, not willing to accept her presence in his life. He actually finally decided to accept her as his mother on the same day he would unknowingly be sent to the Digital World, ordering a bouquet for her and his father's third Stuck In Sakkakumon With You wedding anniversary and making the decision to call her "mom". When he and the others returned to the Real World, he was able to fulfill his task, graciously presenting his wonderfully surprised stepmother some flowers. He was also later reunited with his birth mother with the help of Koichi.

Digimon Forms[]

Koji wields AncientGarurumon's power through the Spirits of Light. In Digimon BattleSpirit 2, Koji can become AncientGarurumon himself as a "finishing" move. If Lobomon fills up his power meter, he can warp digivolve into AncientGarurumon and slash his swords at his opponent.

H Spirit of Light

Lobomon is Koji's Digimon form when he uses the Human Spirit of Light. Lobomon first appears in episode 2 of Digimon Frontier. Tommy Himi and J.P. Shibayama were being chased by a group of Pagumon and fell into a mysterious chamber. They were found by Koji, who beat off the Pagumon using a pole. However, a Pagumon digivolved into Raremon, and turned the tables against Koji. Takuya Kanbara and Zoe Orimoto arrived, and Takuya proceeded to evolve into Agunimon. However, he lost the fight and reverted to his human form. Trying to push Tommy away from an attack, Takuya accidentally pushed Koji into a deep hole. Raremon's acid attack hit the wall at just the correct spot, releasing a beam of light that revealed Koji's Human Spirit of Light. This allowed Koji to Spirit Digivolve into Lobomon for the first time. He seems to resemble Garurumon (His scarf/armor design, the helmet, and his "Howling Laser" attack)

Koji fights in this form in Digimon BattleSpirit 2.


  • Lobo Kendo (Licht Sieger, lit. "Light Winner"): Uses his "Light Kendo" swords to slice his enemies in two.
  • Howling Laser (Licht Kugel, lit. "Light Ball"): Gathers energy to the weapon on his left wrist, and releases it in a burst of light energy.

KendoGarurumon is Koji's digimon form when he uses the Beast Spirit of Light.

KendoGarurumon first appears when the group fought against Grumblemon. Koji helped some Gotsumon by replacing a gem into the eye of a rock, and released the Beast Spirit of Light. Koji became the first of the group to Spirit Digivolve with a Beast Spirit, turning into KendoGarurumon, and defeats Grumblemon. He had trouble at first controlling the Beast Spirit, but quickly got over it.

This is Koji's digivolution in Digimon BattleSpirit 2.


  • Lupine Laser (Solar Laser): Shoots a beam of energy from his mouth.
  • Howling Star (Speed Star): Uses the "Howling Blades" on his back and "Rocket Skates" on his feet to slice apart the enemy.


BeoWolfmon t

BeoWolfmon is the combined form of both of Koji's spirits. He wields the "Beo Saber" (Trinität, Deu: Trinity).

BeoWolfmon first appears when Koji was trapped within Sakkakumon's Darkness Area. Koji fought, and was defeated by Duskmon, forcing him to revert to his human form. About to be killed by Duskmon, Koji started thinking back to all the things he felt he regretted in his life. His will to continue living wakened Seraphimon's Digi-Egg, upgrading Koji's D-Tector and giving him the power to combine his Beast and Human Spirits.


  • Frozen Hunter (Zweihänder, Deu: Two Hander): Raises his saber forming a giant wolf of light energy, and then takes a slash that is faster than the eye can see.
  • Cleansing Light (Licht Angriff, Deu: Light Attack): Fires missiles and a laser at his opponents.
  • Beo Saber (Trinität, Deu: Trinity): Uses the Beo Saber to attack his opponent.


4-35 Unified Spirit Evolution Spirits (Koji)

MagnaGarurumon is Koji's digimon form when he Unifies the Spirits of Light, Darkness, Thunder, Water and Steel. He initially attacks using the immense firepower in his equipment. When he runs out of ammo, he can detach his armor and attain a form known as MagnaGarurumon (SV), where he loses his flight capabilities but gains more speed and access to melee prowess.

He fights against, and eventually defeats, Dynasmon and Crusadermon alongside EmperorGreymon. This is the form he assumes during most of his fights against Crusadermon. He also fights against the corrupted Cherubimon.

When the Watchmaker summons the heroes of the past to the Fusion universe to help take down Quartzmon, MagnaGarurumon shows up with Ankylomon and Cody Hida to assist in the DigiQuartz. A Great Legendary Hero Gathering! The Digimon All-star Showdown!!
