1x27 - Digimon Tamers

Takato and the others end up at a Chuchidarumon village while being attacked by a motorcycle with no rider. During this time, Impmon, now in the digital world as well, meets a Deva who says can help him digivolve. It turns out the motorcycle named Behemoth is possessing a Metalkoromon. Guilmon manages to push it off but in the act gets possessed. In the end Behemoth falls into a pool of lava but emerges once again with the newly evolved Beelzemon as its rider.
