First I hope to help you with some of the confusion. Basically this is an ISOT, the nations are 'plucked' from there own time line and placed here and they still believe that they are in there own timeline. Hope that helps.

Oh before I forget, like I did before. Disclaimer: I do not own; Code Geass, Hetalia Axis Powers, Mega man or Command and Conquer.

-Over the British Channel-

Aile sat on the edge of her flag ship, the Aerial Aircraft Carrier (AAC) 'Nemesis'. She looked down on to the ocean below thinking why Britain of all the individual nations in her empire would want to break away. (The Imperium covers all of Russia, Europe, The Middle East and Africa) She had been so nice to Britain after the fall of the 'Euro Universe', after all it the home land of her ancestors, yes she is a Brittanian, but she hates it as much if not more than Lelouch, she cast her mind back to the final battle of the 'Fall of the EU' as it became known. 'London was in flames only the palace stood, the last European Bastion of the Euro Universe'. Commanders cursed at there leadership for giving Russia its independence. The original plan was, by the fact many nations were declaring their independence from the EU, and they noticed that Russia had the most developed economy, but the leadership believed that it would fall if independence was given. So the Leadership was given to Russia but it did not fall. Aile was named the Princess of the Empire of the Imperium, and eventually they declared war on the 'EU' taking them totally by surprise as they were dealing with Britannia at the time. Eastern Europe fell before any real resistance came to fight the Imperium but that all fell. The first three way battle of the war was Lisbon, the 'EU' VS Britannia VS the Imperium. The Imperium won by a massive victory. The war then ended in the second three way battle and final battle of the war. London. Britannia tried to re-claim the British Isles but they were defeated by the Imperium and the EU surrendered. The Imperium then invaded the Middle East and they then had a technological breakthrough Atomic energy, this scared Britannia enough to give them the Middle East and then Britannia was sued for peace. Iran and Afghanistan of the former Middle Eastern Federation were given to the Chinese Federation as an act of peace.

"Excuse me, your Majesty?" That drew Aile out of her thoughts.

"Yes, Lieutenant."

"We have just completed our report of all our military capabilities for this operation." He said as he handed the pad to the Princess.

Aile grimaced, these were not the figures she preferred but they would have to do. She would always invade with nothing less than an overwhelming force to crush her enemies this was only half of her standard amount. But it still would be enough to retake the British Isles. There were; two 'Mastodon' heavy assault walkers, one hundred and fifty 'Titan' Mk 2 main battle walkers, two hundred 'Wolverine' Mk 2 anti-infantry recon walkers. For Aircraft there were eighty squadrons of ORCA fighters and bombers, twelve squadrons of Fire hawks and six Harbinger gun ships all on board her six ACC's. Then the Navy there were twelve aircraft carriers, thirty assault destroyers and twelve hundred riptide ACVs which were used for amphibious landings. Finally infantry, five thousand light infantry armed with M-16 pulse rifles and one thousand elite Zone Troopers armed with rail guns.

"What about drop ships?"

"We currently have two thousand drop ships?"

"Ok order the Capitan's and the Admiral to bombard the navy and then land." She said as her cloak flew in the wind.

"Yes, your majesty." The Lieutenant bowed and left to give her orders to the commanding officers. With that, Aile just sighed and looked out over the Channel again.

-Meanwhile, London-

Winston Churchill was sat at his desk, he was about to give a message to his people.

"People of the United Kingdom and Ireland. Just thirty minutes ago I was informed that a large German armada of warships were detected leaving the coast of France and are heading this way. We will meet them and we will fight them, we will never surrender to Hitler and his brutalised hordes, I wish you all good luck and I hope you will cast your prayers to the, pilots, soldiers and sailors whom will be fighting for us in these next few hours."

-Meanwhile, Over Sakhalin-

The Gawain was quickly heading towards Moscow, Lelouch needed to see if his sister was safe. C.C was asleep in the back seat. Lelouch was looking at his mask in his hands. He was thinking of when he came to power.

"ZERO! ZERO! ZERO!" The crowd chanted.

"Thank you, people of Japan. I, President Zero, officially announce that Japan is free from Britannian rule."

"I have spoken with Viceroys Euphemia and Nunnaly and they have agreed to remove all Britannian forces from the USJ. Elections by the people, Japanese and Britannian have had Euphemia elected as my Vice President and Nunnaly as Chancellor of the USJ. We will need people to help lead whom know the plight of the Britannian people and they will help me rule the USJ."

"Thank you, people, now we must work together to unite the Britannian and the Japanese people in Japan." Euphemia said to the crowd.

"Now to the world I will now reveal my identity to you all! And to Commander Kallen Kozuki, Knight Suzaku Kururugi and Vice-President Euphemia my identity hasn't changed since the Black Rebellion." The three of them gasped.

"But how….I mean the Emperor erased your memories didn't he?" Suzaku asked. Zero just laughed at his.

"Yes…he did. But it wore off when i got back to the Black Knights, and that was me saving my commanders from execution." Zero said as he reached for his mask. The audience and soldiers looked up at the mega screen. Zero removed his mask and set it down on the table. Kallen, Euphemia and Suzaku were dumbfounded at the sight of him. Whilst Nunnaly was horrified that her brother was the criminal Zero.

"I reveal my true name to the world. To the students of the Ashford Academy I am known as Lelouch Lamperouge, and to the Britannian Empire I was known as Lelouch vi Britannia a former prince." Many people gasped at this but soon cheered as there leader was honest enough to reveal his true identity.

-Meanwhile, Ashford Academy-

(Lelouch doesn't know this has happened, but I thought you might want to know)

Rolo, Milly and Shirley were watching the broadcast of Lelouch when the girls gasped and Rolo just laughed.

"What took him so long?" Rolo asked to no-one.

"You, mean you knew he was Zero?" Milly asked.

"Yes, and I think I should tell you that I am a member of the Black Knights." The two girls just stared at the screen as Lelouch was reading a speech.

-Meanwhile, Over Russia-

Lelouch was shook from his memories when an unknown voice came on his radio.

"Unidentified aircraft, you are entering Russian Military airspace, give ID and proceed back south."

"It's ok, this is President Lamperouge if the USJ."

"I say again, give ID and proceed south or we will use force." Lelouch was in disbelief why would the Imperium attack him, especially when its leader WAS his sister.

"Unidentified aircraft, you will be escorted to Vladivostok control base; if you do not comply the aircraft will kill you." It took five minutes of the Gawain holding its position for the Aircraft to arrive.

"What the fuck is that?" Lelouch heard a Russian voice on the radio. Lelouch noted that these craft were not VTOL, which was strange as Aile made it common policy for all aircraft in the Imperium Air force to be VTOL. Within the five minutes it took for the Jets to arrive Lelouch had woken C.C.

"We should get out of here." She suggested.

"I agree." Lelouch agreed as he activated the Gawain's jets and made best speed to Sakhalin, he had to figure out just what was happening.

(The next chapter will more focus on the American continental nations)
