In another world, a battle is taking place between good and evil. These two forces have been battling each other for centuries.
And now, these two forces are about to enter a new dimension...
"Dark Vortex!" a dark demonic voice roared as explosions lit the battlefield, smoke and flame rising from the attack's impact.
"Howling Laser!" another voice cried as a beam of light struck it target. A piercing cry was soon heard as he attack made it mark and the attack illuminated the area, revealing a large, bone-like winged creature that snarled at its foes.
The attack came from Koji, who was currently using Lobomon in the battle. His twin brother, Koichi, and his friends, Takuya, J.P., Zoe, and Tommy, were also using their Human Digimon spirits.
The large bird-like Digimon they were fighting was known as Velgemon, the corrupted beast spirit of Darkness. He had open a portal to the human world and they were trying to prevent Velgemon from fleeing into the human world and cause who knows how much havoc. The strangest part was that this wasn't an ordinary Digimon. Velgemon was a virus-like Digimon that needed a living host in order to unlock his full power. The last living host was Koichi, and that didn't end well. So with Velgemon out in the open, he was more vulernable for attack.
Velgemon unleashed his Dark Vortex attack at the Legendary Warriors to just distract them long enough to make a move towards the portal he created.
"Guys! He's getting away!" Koichi said to the others as Loewemon, the purified spirit of Darkness. That's when they noticed Velgemon had almost entered the portal, as the Legendary Warriors followed Velgemon through the portal.
Yet it did have some... unexpected side effects on our heroes...
Takuya noticed sparks flew from his Digivice as the screen glowed light blue. The malfunction seemed to have an effect on him as his body changed shaped. The others were having the same problem as well.
"This is not good..." Koji said when he also saw his Digivice malfunction. He began to feel his body change as well, and he felt pain as he changed into whatever he was turning into.
Then, once the pain subsided, they blacked out.
They were in the human world.
Meanwhile, near an unknown town, Velgemon was on the hunt for another host, knowning he would need one soon or otherwise he couldn't reach full power to destroy the Legendary Warriors.
