Earth, the present day, The Tower of Justice.
"Stop!" cried Clerk Kent a.k.a. Superman, as he and some of the Justice Force members closed in on their target.
"We're taking you down!" Tony Stark a.k.a. Iron man declared.
With that, the Justice Force engaged their target.
Steve Rogers a.k.a. Captain America throwing his shield, Jane Foster a.k.a. Thor hurling her hammer, Superman firing his heat-vision and Barry Allen a.k.a. Flash using his super speed.
All the attacks hit home, knocking the villain to the ground, he seemed defeated.
The villain laughed, "you think you've won?" he asked, "only I know how this all turns out."
"Cease thy prattling, villain!" Thor commanded.
The villain smirked, "none of you know it, yet," he said, "but you already dead."
"What are you talking ab.....?" was all Peter Parker a.k.a. Spiderman could say, before he noticed that he was beginning to evaporate.
He gazed in horror, as the rest of the Justice Force also started to disintegrate.
Soon, there was nothing left of the Justice Force, it was as if they had never been there.
The villain looked over the spot where the Justice Force had been.
"And so ends the Justice Force," the mysterious villain smiled.
Elsewhere.
Twilight Sparkle, Rainbow Dash, Fluttershy, Applejack, Rarity, Pinkie Pie and Sunset Shimmer along with some their superhero friends and teammates (from their superhero team, the Champions) were relaxing at the beach.
Starlight Glimmer was not among them, she had returned to Equestria, which meant that her Mare-Do-Well costume had to be left behind, it was now hanging in Sunset's wardrobe in her apartment.
Along with that, Twilight's brother Shining Armour had been going on dates with Twilight's old dean, who was now Principle of Twilight's old school, Crystal Prep, Cadance and was planning to propose to her at some point.
Everyone was happy and having a good time.
Some of the girls and their friends were enjoying the sunshine, the others were using their powers to enhance their beach experience.
"Ah, what a beautiful day," Sunset Shimmer remarked, leaning back in her sun chair.
"Indeed," Princess Koriand'r a.k.a. Starfire of the Teen Titans nodded, "the day is beautiful." 
Starfire was enjoying her down time with the Champions.
"I don't think anything can ruin this gorgeously beautiful day," Rarity smiled.
"Yeah," Rainbow Dash said, as she return to her surfing time, "there's nothing that can ruin this awesome day," she was accompanied by one of the girl's new friends Lara Dos Santos a.k.a. Shark-Girl, a mutant with the ability to transform into a humanoid shark.
Every since the girls and the rest of The Champions had defeated the fear entity Parallax and saved Green lantern, Hal Jordan. More and more heroes had come out retirement, heroes like: Miracleman, Ragman, Prowler, Icon, etc. 
Along with that, more and more teenage meta humans and mutants were appearing like: Kid Kaiju, Argent, Sunspot, and Lagoon Boy.
In Hal Jordan's absences The Guardians of the Universe had given a green ring to a young teenager named Kyle Rayner. Since they had lantern rings themselves, the CHS Main Seven had begun training him on how to control his ring's power. 
As well as individual heroes, some old superhero teams were beginning to resurface like: Fantastic Four, The Doom Patrol, Power Pack, the Metal Men and the Great Lakes Avengers.
After the mass prison breakout, some villains and evil mutants had managed to be recaptured, but others had managed to evade capture.
The world had undergone an awakening, CHS had decided to open its doors to mutants and inhumans as well as human students, "We are accepting people from all walks of life," Principle Celestia had said.
The government had even agreed to grant mutants equal rights and dismantled the Sentinel programme and shut down all mutant prisons and containment facilities, there were still a few select people, who were opposed to the idea.
Since then, CHS had received more students, the human students didn't seem to mind mutants and inhumans attending the school, eveyone seemed to get along fine.
Piotr "Peter" Rasputin a.k.a. Colossus had accepted Applejack's offer and had started working for her family, at Sweet Apple Acres, helping out Applejack, Big Mac and Apple Bloom when they harvested their apple orchard. He had gotten on well with the Apple family, especially with Apple Bloom, because Colossus himself had a little sister.
"That Colossus is one nice, fella," Granny Smith had said, with a smile.
Just then, back at the beach, the radio, that the girls had been using to listening to music, interrupted everyones merriment.
"breaking news, an unidentified object is attacking downtown," a reporter was saying, "what looks like giant robots are being launched from the object and attacking bystanders, many civilians injured."
"Sounds bad," Pietro Maximoff a.k.a. Quicksliver said, "maybe we should check it out and see if we can help."
"Why, worry?" Cindy Moon a.k.a. Silk, remarked, "the Justice Force probably got the situation under control."
Silk had the similar powers to Peter Parker a.k.a. Spiderman, though her powers were more distant, due her being bitten by the same spider that gave Peter his powers.
Twilight was about to answer, but was interrupted as the news report continued, "something else appears to be exiting the lead object, it appears to be a man."
Shortly after that, a voice came through the radio, "People of the 20th century, I am Kang the Conquer, thousands of civilisations have fallen to my forces, and your city will far no better, no one throughout time, in all of space, has ever been able to best me, all hail Kang!"
When the voice had finished, the news reporter started talking again, "This 'Kang the Conquer' has made his intensions pretty clear, we have no hope of defeating a force like that, this is....."
Before the news reporter could finish he was cut off.
"This is really strange," Twilight said, "surly the Justice Force would have responded to this by now."
"Maybe they're on a break," suggested Doreen Allene Green a.k.a. Squirrel Girl.
"They protect the world 24/7," Rainbow Dash replied, "they can't just vanish like this."
"Maybe they're off world," proposed Applejack.
"Then why didn't someone tell us?" Fluttershy queried.
"Yeah, its very strange indeed," Pinkie Pie nodded.
"Well," Rarity said, finally, "there are innocent people in danger, we can't just sit by while that happens."
Without another word, The girls and the rest of The Champions rushed off to save the day.
Downtown.
The girls and The Champions, some in their street clothes and others in superhero uniforms, arrived on the scene, meeting up with Gwendolyn "Gwen" Poole a.k.a. Gwenpool, another member of The Champions.
"Whoa," Rainbow Dash said, looking up at the gigantic ship, which was shaped like a sword, hanging in the sky above the city, "that's one big ship."
"Has anyone seen Superman or Ironman?" Sunset asked, some nearby civilians.
"Forgive me for asking," one of the civilians replied, "who?"
"You know, Superman, the Man of Steel and Ironman, the Iron Avenger," Pinkie Pie answered.
"Sorry," another civilian responded, "but there's never been Superman or Ironman here at all."
"This is a joke, right?" Rainbow Dash said, "Superman is the greatest hero on the planet."
"Are you having a laugh?" a nearby police officer asked, "I don't know anyone called Superman around here or anywhere."
"Guys, the whole city has gone nuts," Quicksilver replied, dashing over to the group, "I keep asking if anyone has seen The Justice Force and everyone thinks I'm making names up."
"What is going on?!" Twilight asked out loud.
The girls and The Champions all stared around them, in shock and horror.
