With the power to Biomerge on earth granted to them, the Tamers are able to fight the D-Reaper more evenly, but trouble follows when Takato and Guilmon are sucked inside.
Using Dobermon's gift, Henry, Rika and Takato biomerge to form Gallantmon, MegaGargomon and Sakuyamon. The three Megas attack the D-Reaper and destroy many drones. Elsewhere Daisy starts to work on repairing the Ark, while Kenta, Kazu and Suzie decide to go and help the others. Kazu flies in on Guardromon, Kenta and MarineAngemon walk, and Suzie digivolves Lopmon to Antylamon, who leaves on her own. At the battlefield, Gallantmon gets grabbed by the D-Reaper and dragged inside. Gallantmon cannot hold his Mega form so he lands in the park, which is still untouched. Takato wonders why the park is still untouched. Jeri appears and says that the organisms cannot be proccessed. Takato tells Jeri how worried he has been. Jeri starts talking about how Jeri's mind is full of sorrow. Guilmon tells Takato that she isn't the real Jeri, as the imposter unveils purple wings and reveals herself as an Agent of the D-Reaper. Outside the D-Reaper, Calumon tries to go to the battlefield, but Impmon stops him. Guardromon and Kenta arrive, but are overlooked due to the appearance of a mysterious new Digimon.
