S2·E48 Oikawa's Shame

Oikawa attempts to bring the children to the Digital World, but because BlackWarGreymon had sealed Highton View Terrace's portal, they end up in the Dream World. Oikawa's possession manifests as Myotismon, who Digivolves into MaloMyotismon using the Dark Spores and kills Arukenimon and Mummymon. The DigiDestined become fearful, with the exception of Davis and ExVeemon.
