Elements of the prophecy begin to come true: bats appear in the sky,
the captured residents of Odaiba call out Myotismon's name in a trance,
Gatomon digivolves into Angewomon, and Myotismon rises again, revealing
himself in his "true" form -- VenomMyotismon
-- a towering, energy-devouring
monster. This is the first time the digidestined realize there is
a "Mega" level of digimon.
In an attempt to bring about the last part of the prophecy, Angemon
and Angewomon shoot arrows of light at Tai and Matt, causing Agumon and
Gabumon to "warp-digivolve" into their ultimate selves:
WarGreymon and MetalGarurumon.
