I don't own Digimon
Prologue four years ago
Okay so a couple of years back there was this digi-egg on the web. Izzy discovered it and informed Tai about it. Gennai contacted them and sent their digimon Agumon and Tentomon into the Internet they fought this digimon valiantly but it digivolved to fast for them and beat them.
But it was not over yet Tai had been able to contact Matt and his little Brother TK and their digimon were sent in as the cavalry Gabumon and Patamon.
With backup Agumon Gabumon Warp digivolved to Wargreymon and Metalgarurumon and took the fight to this new foe but even with the two Mega's that had defeated the dark masters he was still to powerful for them. This was made worse by the fact that kids from all over the world were sending Emails and it was slowing the two digimon down and the fact the digimon who had called itself Diaboromon had taken out Patamon and Tentomon.
What was worse was the fact that Diaboromon started to make copy's of himself pretty soon their we're over a million copies of him. The emails were coming in faster then ever despite Izzy's best efforts Wargreymon and Metalgarurumon were quickly defeated. But when things looked bleak the bond between Tai and Wargreymon and Matt and Metalgarurumon was so so strong that they themselves became digital and convinced there Digimon to not give up. With the children of the world behind them Wargreymon and Metalgarurumon regained their strength and for the first time DNA Digivolved in to the royal knight Omnimon.
Now the tables were turned Omnimon swiftly destroyed the Diaboromon copies but the original was still to fast for them and time was running out But Izzy living up to his crest of knowledge he sent all the emails he had received to Diaboromon and the slowing down that had given him an advantage was now his downfall now slowing down left a window for the royal knight to stab his sword into the head of Diaboromon deleting him.
But as we all know Digimon never really die they are just reconfigured then reborn Now it looks like it is up to the younger generation of DigiDestined to keep an eye out in case he decides to reappear.
