Imperium Invasion

The **Imperium Invasion** was a huge invasion battle from *Justice League*. It deals with a bunch of heroes coming to together to protect the Earth from being invaded by alien shapeshifters called the Imperium who have come to prey upon the Earth. The battle takes place in the three-part series premiere, "Secret Origins."

## History

### Background

It all started with a parasitic blob-like alien race called the Imperium who came from the deep reaches of space. They survived by praying upon peaceful planets and civilizations. Then one day about one thousand Earth years ago, they arrived on Mars through meteors and attacked it, forcing the Martians who lived on the planet to fight back against the Imperium. The fight lasted for centuries with the Imperium eventually capturing and enslaving the Martians then gaining their ability to shapeshift and read minds. But a resistance group of Martians were able to stop the Imperium with a special nerve gas that paralyzed them but in the process, the Martians were all wipe out with the sole survivor being a Martian named Martian Manhunter who sealed up the paralyzed Imperium behind an underground chamber and later went into hibernation ever since. But five hundred years later, the Imperium were accidently awakened from their paralysis by two astronauts from Earth named J. Allen Carter and Ed Reiss who discovered their underground prison and were later killed them. One of the Imperium then disguised itself as J. Allen Carter and returned to Earth to as a spy to prep the Earth for invasion by becoming a Senator to sabotage the Earth's defenses and disarming all of their powerful weapons with help from Superman who was unaware of it. Which the spy claimed was all for the protection of the Earth. Martian Manhunter was also awakened and went to Earth to try and stop the Imperium by warning the people of Earth but they didn't listen to him and he got captured by the Government. During which, some Imperium agents also came to Earth to prep the planet for invasion by sabotaging it's space exploration facilities so Earth wouldn't find out about the invasion which they did by capturing certain people and taking their places. When both Batman and Super Man started to investigate the Imperium agents after fighting them off, a meteor crashed on Earth and the entire Imperium fleet emerged from it.

### The Battle

The fleet attacks Metropolis with Superman and Batman trying fighting it off but Superman gets mentally called away by Martian Manhunter to help free him from the Government facility he is imprisoned in with Batman following him. Which leaves the fight in the hands of the military who fight off the Imperium fleet using jets and missiles but then more fleets arrive and attack different parts of the world with more arriving by the hour. Batman goes looking for Superman and finds Martian Manhunter, who takes a humanoid form. When they try to leave they are confronted by the army which is actually the Imperium in disguise who attack. Batman, Superman, and Martian Manhunter try to fight them off but make a hasty retreat. The Imperium follow them but then they get help from Green Lantern, Hawk Girl, Wonder Woman, and The Flash who were also summoned by Martian Manhunter. He tells them all about the Imperium and how they destroyed Mars, and they all decide to stop them. But then large Imperium smog factories burst out of the meteors and start to smog up the sky to block out the sun so the Imperium can survive. The heroes decide to split up into teams to take out all the factories. But during a fight both Superman and Hawk Girl get captured, so Batman, Wonder Woman, and Martian Manhunter go to save them and in the process find the factory's central core. They destroy it which destroys the whole factory. But Batman ends up getting captured as well in the process.

Meanwhile, the Imperium mother ship arrives which throws the world into a planet. The remaining heroes regroup and plan to rescue the others by taking out the Imperium machines and getting into the factory in Metropolis. Martian Manhunter then takes out some of the guards by impersonating them. Then find Superman and Hawk Girl but its a trap, the heroes get knocked out and captured where they reunited with the real Superman and Hawk Girl. They are confronted by the Imperium and their leader which is a giant Imperium brain. The brain tries to kill Martian Manhunter by absorbing him into it. But Batman arrives and reverses the factory process, clearing up the sky. This causes the Imperium to burn up in the sunlight including the brain. The heroes escape and fight off the Imperium while the brain tries to escape but the heroes stop it. The heroes then free everyone who was captured by the Imperium. The remining Imperium fleet then escapes, while the heroes take care of what's left of them on Earth, ending the invasion.

### Aftermath

With the defeat of the Imperium the world wonder what to do when they come back. So Batman and Superman get an idea and all the heroes join forces as a team called the Justice League. He even has a satellite headquarters place near the Earth to watch over it.
