Prophecy

With the mysterious fog still looming, the group try to decode a prophecy which, according to Gennai, holds the key to defeating Myotismon once and for all.

Synopsis
As everyone tries to decide on the next course of action, Izzy receives an ancient prophecy from Gennai, describing an undead king rising, and how he is defeated. Not much later, the first parts of the prophecy begin to come true, and Myotismon is resurrected as VenomMyotismon. Even with Angemon and Angewomon, the Digimon cannot defeat VenomMyotismon, so they look to the rest of the prophecy. It's concluded that the two angel Digimon, Angemon and Angewomon, must fire arrows of light at Tai and Matt, which cause Agumon and Gabumon to digivolve to their mega forms, WarGreymon and MetalGarurumon.
