The Last Miracle, The Last Power

'''The ’s ultimate enemy, digivolves. And the Great Catastrophe consumes both the Digital World as well as the human world.'''

Summary
As the DigiDestined and their Mega partners charge towards Negamon, sensing their approach, Negamon soon turns hostile, digivolving into Negamon (Giant) to attack them to prevent them from stopping it as it begins invading the Real World, causing anomalies all over the world, and causing many news outlets to issue a state of emergency to the public to steer clear of the tentacles as they begin to affect electronics everywhere the tentacles are appearing.

Though Ophanimon, Seraphimon, WarGreymon, and MetalGarurumon reach Negamon's core and attack it while Rosemon, HerculesKabuterimon, Vikemon, and Phoenixmon go for the tentacles to sever Negamon's attempt to attack the Real World, the effort seems to succeed, but Negamon (Giant) fused with the black orb to summon a Mega form to protect itself, Abbadomon, and manages to overwhelm Joe, Izzy, Sora, and Mimi, trapping them in a void where they have become garbage data to await deletion. Meanwhile, Tai, Matt, Kari, and T.K. continue their assault on Abbadomon, but it seems their attacks are not having an effect on it as it proves too powerful. However, it is then that the people of Earth, having seen the battle through the voids in the sky in the Real World, begin sending emails of encouragement to the DigiDestined, believing in them. This allows Joe, Sora, Mimi, and Izzy to regain their physical forms and allow their partners to warp digivolve back into their Mega forms, before sending that light of hope to Tai and Matt. Following a short appearance by Devimon and SkullKnightmon to commend their good selves on their success and protect them from the tentacles, Seraphimon and Ophanimon send the power to WarGreymon and MetalGarurumon, allowing them to DNA Digivolve once more into Omnimon, who breaks open a gap in Abbadomon's head to infiltrate it and deal with Negamon once and for all to end the Great Catastrophe.
