The Battle for Earth

VenomMyotismon is finally defeated, though things only get weirder as strange images of the digital world appear in the sky, suggesting that something is terribly wrong.

Synopsis
With new found strength, the two Mega Digimon begin taking on VenomMyotismon. Things seem to be going well until VenomMyotismon is cut open to reveal a powerful energy source, which pushes the Digimon away. But at that point, the kids' digivices shoot beams of light, binding VenomMyotismon, and giving WarGreymon and MetalGarurumon a clear shot at the weakpoint - Myotismon is finally defeated. As things begin to return to normal, everyone's relieved, until the vanishing fog reveals something even stranger in the night sky. It's an upsidedown image of the familiar landmass that Izzy later identifies as the Digital World, showing that while the digidestined have been fighting Myotismon for only a few days centuries have passed in the digital world revealing that something is terribly wrong. After rescuing a plane damaged by the image in the sky, the kids decide to head back to the digital world right away to investigate and sort the problem out. Now they must face an evil that can bring forth more destruction and darkness than even Myotismon.
