Ice Ice Baby.Takuya and Koji evolve to EmperorGreymon and MagnaGarurumon and battle Cherubimon after getting their friends to safety on Cherubimon's castle. Eventually they defeat him, but he disappears and his castle is destroyed. Koichi nearly falls to his death during the escape, but is saved by MagnaGarurumon. While the group is wondering what to do next, an IceDevimon arrives that according to Bokomon went on a rampage across the Digital World, killing Digimon and absorbing their data. Eventually an army defeated him, but he was too powerful for even Cherubimon to kill so he was imprisoned beneath his castle and escaped when it was destroyed. He quickly freezes Takuya and Koji's D-Tectors so they can't fight and engages the others who spirit evolve to fight him. IceDevimon proves too powerful for the group and traps Kazemon and Beetlemon. Kumamon and Löwemon evolve into Korikakumon and JägerLöwemon, but are unable to defeat him and he traps Takuya and Koji in a bubble in which they slowly freeze. JägerLöwemon frees them and has Korikakumon free the others. Beetlemon and Kazemon quickly evolve into MetalKabuterimon and Zephyrmon and Korikakumon and Zephyrmon use their wind and ice to freeze IceDevimon, holding him in place while MetalKabuterimon blasts him, cracking and weakening him. With IceDevimon weakened, JägerLöwemon is able to destroy him and turn back into Löwemon to purify him. With IceDevimon gone, Takuya and Koji's D-Tectors return to normal and Koichi is accepted as a full member of the group. However, Cherubimon is revealed not to be dead and still collecting data to himself in the ruins of his castle, causing them to realize that it is not over yet.
