Koichi's sacrifice enables Takuya and Koji to become Susanoomon, a being formed from all twenty spirits. With this power, Lucemon is finally defeated and scanned, but this only makes things worse. Only the good part is scanned, leaving a colossal dragon composed of pure evil and with the power of the entire Digital World headed straight for Earth.
Takuya and Kojispirit evolve into Susanoomon and get ready to face off against Lucemon Chaos Mode. The fighting starts, and Lucemon uses the same Paradise Lost Combo which destroyed the moons, but it is countered by Susanoomon. As Susanoomon retaliates, harming Lucemon for the first time, Lucemon considers the possibility of failure. The idea enrages him to the point of attacking with the same attack which defeated Koichi, which comes close to destroying Susanoomon. Inside Susanoomon, Koji and Takuya think over all that has happened to them, giving them strength. They willingly separate to escape the attack and recombine to take Lucemon out. They scan his data but only gets his good data, which tries to purify the Dark Area. Lucemon's evil data, however, absorbs the Dark Area's fractal code and turns into Lucemon Shadowlord Mode. Everyone give chase as Lucemon tries to get into the Human World, finding strength from their personal growth in their journies. Lucemon ascends to the Human World through the underground train station, and electrical surges occur all around Shibuya, taking with its Lucemon's message: "You Must Choose To Follow Me Or Be Destroyed". Meanwhile, the DigiDestined finally catch up with him, but Lucemon regenerates too fast for them to damage, and he easily repels them.
