Metropolis
Batman and The Flash stop at a nearby warehouse. They take some rest and scout the area for crime nearby. The sky is grey, as it has been everywhere, with red lightning striking the skies. There were no changes in weather, just the same weather all around.
"Do you think that 'Superman' guy will know what that is?" The Flash said, pointing at the cubic device Batman held. Batman didn't reply and kept walking. Suddenly, figures came out of the red lightning; they were flying out of the sky and in all directions. Some were headed straight for the duo.
"Fuck! This isn't good," said the Flash. Batman took out three Batarangs and threw them at the coming hordes. The Batarangs stuck to the demons and exploded, knocking back most of them. The Flash raced around the demons, clearing out five at a time by punching them. Batman punched a demon in the face and dodged one, doing a backflip and throwing a flash-bang, blinding the nearby demons and the Flash cleared them out, the lightning fast flurry of punches sending the demons flying. They know there are more, but they also know that they couldn't continue this pace for much longer.
The Daily Planet
Clark Kent is working on a story about Superman. If only they knew it was me, he thought to himself. He typed extremely fast on the typewriter, doing his job. A woman approached him, by the name of Lois Lane.
"Hey Clark, what you working on?" Lois asked.
"Nothing, just an article on Superman," Clark replied.
"I was wondering if we could-"BOOM! Figures suddenly smashed into the windows of the Daily Planet. Figures that were flying out of the sky were taking the civilians captive and then flying out. Clark ran in the ensuing chaos, going into an elevator and ripped his shirt off, revealing the S shield. He flew out, his suit becoming Superman. Flying out of the Daily Planet, he flew at full speed towards the demons flying out of the sky, smashing into them and watching them fall into the ground below. Demons saw him and flew at him, attacking him. Superman punched them with thunderous force, using his heat vision and throwing them away into other demons. More of them piled up on Superman and he was blasted by them, sending him flying hard into a roof of a warehouse nearby, smashing hard into it and completely destroying it.
Batman and The Flash fought the demons with ease but their fatigue levels were growing higher by the minute. Batman kicked a demon in the face before then countering another and smashing it into a wall. The Flash was dodging the blows of demons and swatted them away with whirling punches. Their fight was interrupted by the sound of a collapsing warehouse. The duo and the demons turned and saw a body that laid there. It stood up slowly and Batman saw who it was. The Kryptonian, Superman. Batman kept fighting, throwing punches that knocked out the demons and countered the demons with ease.
Superman stood up, looking around. He saw two figures, one black and one scarlet, fighting against the countless demons that were around them. He had to help and flew into the scene, tackling a row of demons and smashing them into a wall. A red and blue blur appeared in place of the Superman, his speed and strength combined was no match for the demons as they were completely overwhelmed and defeated in no time at all. The demons retreated, leaving Batman, The Flash and Superman alone.
"Why have you come here?" Superman asked with slight authority. "Are you-"
"No, we're not one of them. We are here to give you this," Batman said as he handed the cubic device to Superman. "I was thinking you may know about this device, maybe of your alien origin."
Superman studied the device, using his X-Ray vision to see its components. He held it in his hand. "These are boom tubes. I have seen these before, but not for a long time. It is not Kryptonian technology. I know it when I see it."
"What the hell do these things do?" asked the Flash.
"It's a teleportation device, used to transport armies or individuals from one galaxy to another." Batman replied. "You will hear booms when it is activated, to signal teleportation."
"I heard numerous of these booms, maybe there is an army out to invade Earth," Superman said. "We should work together to contain them. Before we make up plans, who are you?"
"I'm the Flash."
"I'm Batman."
Coast City
The invasion of these demons has already reached its most intense in Coast City. Blasts and explosions rocked the city itself and flashes of green could be seen amidst the explosions. Green Lantern was protecting his city in the sky, creating constructs of shields and guns to take down the demons. He was using as much power as he could from his power ring and has even made lengths to create turrets around the nearby buildings that destroyed most of the demons in mid-flight before they reached the city.
"Damn it, there's too many!" Green Lantern, also known as Hal Jordan, said to himself. "I can't hold out more of them much longer. He was relatively unscathed but he was running out of energy. He created more constructs like planes, sledgehammers, buses, machine guns, missile launchers and more defences to keep them from breaching the city. A blast hit Green Lantern straight in the chest, which sent him flying into the sea and into the nearby coastal area. He stood up slowly and was about to fly up when a man from the sea jumped and kicked him. He stumbled backwards into a crouching position. This man was wearing orange scaly armor, holding a trident in one hand and dragging a demon in the other. He walked towards the Lantern, holding the tip of his trident at the Green Lantern's face.
"Are you responsible for this?!" the man from the ocean asked with rage, pointing at the demon. "These things are destroying my kingdom! Where is your leader?"
"I'm not responsible for those things." Green Lantern replied. "I'm defending my city against these things as well. Who are you, anyway?"
The man from the sea lowered his trident and stood straight up. "I am Aquaman, King of Atlantis! And who are you, human?"
"I am the protector of Sector 2814, Green Lantern." Green Lantern replied. Before any of them could speak, more explosions rocked the skies. Demons were coming out in all directions now, coming for them.
"Are you coming to protect the city or not?" Green Lantern asked. "Do you even have any powers besides breathing in the water?"
Aquaman didn't reply. He turned his back on him and sent out an echo to the sea. The demons flew at them at faster speeds, and they were greeted by numerous massive sharks, rising from the oceans and devouring the demons before then submerging. Shit, Green Lantern thought. Before he could say anything, he saw another squad of the flying demons coming towards them.
Green Lantern fired a missile towards the demons. "We've got company!" he said as he created constructs that blasted the demons out of the skies. Aquaman leaped up in the air, grabbing a demon and throwing him into the city and then swiftly stabbing another with his trident and smashing him into the ground below and landing. More of the demons landed on the ground around them. They stood back to back, getting ready for an attack.
"You know how to kill these things?" asked Green Lantern.
"Don't doubt the King of Atlantis," Aquaman replied, slightly offended. Aquaman held his trident and ran straight towards the group and slaughtered with his trident. Green Lantern smiled and formed a construct of a machine gun, firing bullets towards the demons.
Superman, Batman and The Flash were fighting as hard as they could to contain the alien invasion. Batman defeated most of the demons headed his way and saw that Superman was being overwhelmed. Superman merely threw them out of the way and slammed a bus at them, while the Flash was dodging most attacks and punching them out of the way. Batman evaded a blast headed straight for him.
"We can't continue like this, there's too many!" Batman said to his allies. "We have to retreat!"
Superman and The Flash nodded at the Dark Knight and managed to defeat the rest of them before hiding. Batman walked in the shadows of the city and managed to stay undetected. He turned to find armies of these demons assembling.
"There's going to be too many for us to fight, even for you, Superman," Batman said. "Even if we defeated them, there will be more to attack us."
"Then we need more people to help, people that are willing," Superman replied.
"I may know of someone," said The Flash.
"Who?"
"The Green Lantern."
