Dr. Kogami is a sick man, who rests in a pod. He has tan skin and wears a grey outfit. Inside LINK VRAINS, Dr. Kogami is a tall man, who has fair skin. He has black and grey hair and mustache, and has yellow eyes. He wears a white coat with red outlines, a dark undershirt with red stripe, some black pants and a pair of brown shoes.
Like Revolver, Dr. Kogami believes Ai to be a threat. However, since he did construct Ignis beings, he has slight regret about destroying them.
Dr. Kogami can teleport himself inside LINK VRAINS. In addition, he has superior programming and hacking skills, even helping out his son in dire need from a remote distance.
Dr. Kogami successfully gave free will to A.I. programs and named his creation Ignis. At some point in time, Dr. Kogami's real body fell into a comatose state, requiring his son to take care of it in his stead.
Dr. Kogami and Revolver discussed about a new program. He said that he worked on a few new ideas but he needed more time. After Blue Angel was defeated by Playmarker, Revolver was certain that Playmaker would have to comply to his demands. Dr. Kogami said Ignis had to be destroyed and Revolver was concerned about Kogami since he designed Ignis. Kogami told Revolver was a painful decision to destroy the AI, while Revolver reminded the importance of destroying Ignis and Cyberse.
During Revolver's Speed Duel against Playmaker, the latter had Ai conjure a Data Storm. Revolver was glad, as this allowed Dr. Kogami to send a card to Revolver. Dr. Kogami watched the Duel between Playmaker and Revolver, and wished of the latter to take Ignis back. Much to his surprise, Playmaker summoned the "Firewall Dragon" and destroyed the "Skyfire Prison". Dr. Kogami was still pleased, as Playmaker had 600 LP left, and expected of Revolver to take him down. Dr. Kogami was surprised how Playmaker wanted revenge for what had happened 10 years ago. Specter arrived, noting how scary the fate can be. As Revolver returned, Dr. Kogami was surprised how he let his guard down, seeing it was about that incident Playmaker spoke. Revolver apologized to him as his father, and as his hand recovered, claimed next time would be different. His father stated that Revolver didn't need to think of that, and seeing how they could not retrieve Ai, he went to execute the other plan, and needed time to make preparations for that.
