Warning: This story contains massive spoilers for the Anime and Manga of Attack on Titan as well as spoilers for Code Geass. If you don't want to be spoiled, don't continue. Just GTFO while you can. I remember having AoT Chapter 82 spoiled for me and well, it hurt.

Disclaimer: I don't own Attack on Titan, Hanjime Isayama and Studio Wit own that. I also don't have the rights to Code Geass, that is Sunrise Studio's property, and I am making no money off of this work.

A/N: It has been about a week since putting my HP/CG story on ice, and I still have no motivation for it. Anyways, keep in mind that this is one of my first attempts at writing, and enjoy.

Northern Edge of the Forest of Giant Trees

Armin was currently on a branch about 40 meters above the ground, holding his position and keeping watch as he was ordered to. He was trying not to look down, due to not only the fact that the ground was 40 meters away, but also because of the massive titans trying to reach him, and failing. So instead, Armin shared glances with his squad mates and scanned the horizon. Why are we just standing guard outside the forest, and what is the commander trying to do by having the Female Titan enter the forest? In fact, why did we even come to the for-. His train of thought was interrupted by the sound of… some sort of gunshot, and then the sound of hundreds of explosions.

Armin was by no means an idiot, and instantly came to the conclusion that those were not cannons. The fact that no one had seen them in the wagon, plus the fact that the number needed for what he heard was far more than the entirety of the Survey Corps Supply Division could possibly carry, had put Armin at a stump as to what the sound was. He saw some of his friends wonder about the shots, even ask, "What was that?" but none left their posts.

Perhaps it's some kind of secret weapon? But how could they have set it up when the Female Titan is chasing them. Unless-. No. They can't have known about it. They can't be trying to CAPTURE the thing. As he worked through the possibilities, he remembered that there was an abnormally large amount of Explosive Deployed Stabilization Wire launchers, and with the speed they moved, they could penetrate a titan's skin.

So, Armin decided that they were trying to capture the Female Titan, how they were, but couldn't figure out how they knew about the Female Titan. He would have keep think about this problem if not for the fact that he saw a very large object off on the horizon and to the east. That thing has to be massive for it to be that size coming over the horizon. The horizon is at least 20 kilometers away and that object is still coming over it. Could it be a titan? No, it's too big for it to possibly move at the rate it is. In fac-. Is it flying? The thing had to be at least 40 meters tall and moving at the speed of one of the Survey Corp's horses.

"Jean, do you see that thing off in the distance moving towards us?" Armin pointed in its direction.

"Yes, what the hell is it though? It is at least as tall as we are high. Is it even flying?" Jean had a slightly worried look on his face.

"I think it is. Do you have any ideas as to what it is?"

"No, and I don't think I want to know."

Command Bridge of the Avalon

"AS-1, do we have the results of the material tests on the wall we encountered?" asked a violet-eyed and raven haired man, who stood at the front of the bridge, to a person sitting at the science officer console.

"We do, sir." Replied AS-1, with a slightly robotic voice. "It says that the wall is at least 400 years old, but that is not the most interesting part, sir. The wall appears to be made entirely of TS4."

"Ah, this is interesting in that the wall is made of titan crystal. It does seem like something that George would have done though." The raven haired man paused for a second before asking, "What do you three think of this?" directing the question to the three standing to his sides. The first being a green-haired 'witch,' the second being a Japanese man with brown hair, and the third being a Japanese woman with red hair.

"This definitely seems like something that the insane bastard would do, thinking that the world should be ruled by titans." This was said almost immediately by the other man. The two women just nodded in agreement with the man.

"Sir! We are picking up massive heat signatures in the forest up ahead. At least 50 titans in and around it, as well as gunpowder going off in there." This interruption came in a robotic voice, but from the intelligence officer console.

"Thank you for the information AI-1. AN-1, set course for that forest. AE-1, get the engines to flank speed. AFC-1, order the Gawain, Lancelot, and Guren to be prepped for launch. There could still be survivors." This was said to the navigation, engineering, and flight control officers respectively from the commander of the Avalon.

"Lelouch, do you think that the survivors will last long enough for us to reach them?" this came from the brown haired man to the commander.

"Yes, if they lived in these walls for as long as they did, they must have some sort of military and contingency plans." Lelouch then turned around and started to walk to the bridge door. "Same as usual, C.C, you're with me," he said looking at the green-haired woman, "Suzaku gets the Lancelot," looking to the brown haired man, "And Kallen gets her Guren," looking at the red-head. The other three nodded at Lelouch before all four headed for the hanger bay.

Avalon Hanger Bay

"Emperor Squadron, this is AFC-1, K-1 is to taxi to central catapult. Q-1 taxi to port catapult. N-1 taxi to starboard catapult."

A series of affirmatives met the controller's commands, and the knightmare frames all taxied to the respective catapults. After a few seconds of waiting, they heard, "Emperor Squadron, all crew have cleared the area. Clear for launch in 5, 4, 3, 2, 1."

At this, the knightmare pilots replied, "Gawain Mark Two launching!" "Guren Type-09 launching!" "Lancelot Arthur launching!"

Well, this is done. I hope that you enjoyed this first chapter. Tell me what you think, did I screw up? Did I do okay? Ask questions, and I will answer if I am not going to use them in the plot or are part of it.
