Saigo no Kessen! Kouki, Kyûkyoku Shinka

By incapacitating ElDoradimons' movements, Kurata opened up a massive digital gate that sucks the titanic Digimon along with all his inhabitants to realise into the human world. Once more in the human world, Kouki challenges both Marcus and Agumon for a final showdown to determine the stronger fighter between both. Kouki surprises them by bio-digivolving into BioDarkDramon.
