Brainstormed it last night. Here's an idea pitch.
When the Digital World fell into great turmoil at the hands of the evil Digimon of the Dark Area, the God of the Digital World, Yggdrasil, proposed a battle. This battle will determine the strongest Digimon in the Digital World who will destroy this evil. He says, "It will take great valor, strength, and unity to vanquish the evil Digimon of the Dark Area, the Nightmare Soldiers! I assure you, the champion of this battle will become our savior!"
But to draw out a Digimon's fullest potential, he had to rely on a human's help. Though distrustful of humans, Yggdrasil decided to use the humans for this purpose, in hoping that this experiment would destroy each other. 24 Digimon, each as Rookies, were selected. 24 children were brought (or stolen) from their world. 24 devices, symboled from the greek letters Alpha to Omega, were created and given to these children. And Yggdrasil said at the beginning of the battle,
"In the beginning, there is destruction. In the end, there is creation. And in the middle, there is evolution."

The Hibiki plot I structured more from Frontier, but rather than "Digimon Warriors" or whatever, I used "Digimon DNA" as the transformation catalyst. I have a plot for that too, but right now, I'm still working on it.
