New Challengers Competing

Everyone from the various worlds watched as their friends, family and loved ones were all sent back to the room where they first arrived, while some of them had a few injuries, others had taken more serious attacks, but were still alive.
It was then all the heroes turned to the large monitor to see the Champion Hunter's shadowed form, in which he then told the Duelists, Digimon, Digidestined, Tamers, Legendry Warriors, DATS members, Pokémon Trainers, Pokémon, ninjas, Superman, Green Lantern and humans from Karakura Town. "Bravo to all of you. You have indeed proven to be worthy competitors of Death Zone, except for one small thing. Now what was it? Oh, that's right, none of you killed your enemies!"
"And we're not about to start." Superman countered.
"So you may as well let us go!" Zoe angrily stated.
"I don't think so. You will fight and you will take down your enemy, only then will I let you go. But I know you won't take down a fellow hero, so you'll each take on some of the greatest evils of each of your worlds." The Champion Hunter replied, before he stated. "So, I suggest you find out all you can about the enemies you may face, as tomorrow not only will your lives be on the line, but the lives of those from everybody's world, as the 'new competition' has no reluctance in destroying you for a chance at revenge and taking over every reality they can."
The monitor then shut off.
"I don't trust the Champion Hunter. We're going to find out who you guys will be up against." Superman and Green Lantern flew off to discover exactly what the rest of the group was dealing with.
-The next day-
After all the heroes were escorted by the Champion Hunter's robotic henchmen back to the main hall of Death Zone, they watched as the familiar shadowed figure of the Champion Hunter appeared on the monitor and then said. "Good morning to you all. I hope you all slept well."
"Skip the pleasantries and just show us our opponents." Gatomon snapped back, however, she, along with the other heroes were confused when the Champion Hunter laughed at the white furred feline Digimon's demand and then replied in a sinister tone. "I'm afraid to save time, as the audience craves to see your downfall, you will not know who you will be fighting."
It was then before anyone could reply that they were engulfed by the familiar red darkness, in which they were sent to face against unknown evils to earn their freedom, save their world and the world they would be fighting for.
