Kouki Tsubasa

Kouki is one of the modified (seemingly) human individuals with the power to turn into a Digimon through the process of Bio-Hybrid Digivolution. He is the supposed leader of the Bio-Hybrids. He first appeared to defeat Akihiro Kurata from Keenan Crier and Crowmon. He then appeared before the DATS group, where he clashed fists with Marcus Damon which ignited his D.N.A. - an act that alerted everyone to the fact that he was no mere human. However, both he and his comrades' attacks were halted by Commander Richard Sampson and Kudamon. In the epilogue (5 years later), Kouki made an appearance as a motorcyclist without a helmet, pursued by Yoshino Fujieda's police wagon. His Digivice is Blue/Gray.

Digimon forms
As a Bio-Hybrid, Kouki has access to two different forms, one stronger than the other.
