Nanami- After the DATS building was destroyed, she and Ivan chased after Sampson, and later fought Miki, Megumi, and the two PawnChessmon before facing Marcus and the others along with both her colleagues. She dresses rather oddly, carrying an umbrella, and wearing clothing in the style of a Gothic. is also something of a genius herself, and used her intelligence to counter the battle strategies of Thomas after gaining the ability to become BioLotusmon. However, Nanami was defeated when Thomas used an attack that was reminiscent of Marcus' reckless fighting style. In the last episode, Nanami was also rising her DNA into the sky. Her Digivice is Burgandy/Gray.

Ivan seems to have difficulty with-holding his inner thoughts, and tends to blurt out what he's thinking without realizing it. After meeting her for the first time, he developed a sort of attraction towards Yoshi (calling her his "beloved honey" at one point). After gaining his ability to assume his final form, this prompted him to engage Rosemon in a duel for Yoshi's love, only for him to be defeated at their hands.In the same episode this battle occurred in, it was revealed that Ivan is something of a mercenary, and underwent his transformation into a BioHybrid for the sake of money. It was also learned that he also had many brothers and sisters, and that he was fighting for their sakes. In the last episode, Ivan was also rising his DNA into the sky, together with his brothers and sisters. His Digivice is Brown/Gray. Ivan is apparently Russian.

Kouki is one of the modified (seemingly) human individuals with the power to turn into a Digimon through the process of Hyper Bio Evolution. He is the supposed leader of the group. He first appeared to defend Kurata from Keenan and Crowmon. He then appeared before the series' heroes, where he clashed fists with Marcus which ignited his DNA - an act that alerted everyone to the fact that he was no mere human. However, both his and his comrades' attack were halted by Sampson and Kudamon. In the epilogue (5 years later), Kouki made an appearance as a motorcyclist without helmet, pursued by Yoshi's police wagon soon. His Digivice is Blue/Gray.
