AN: MK here with his first Code Geass fanfic! WHOOOO! Science fiction, now THAT'S my territory… Hehehehe. I'll put those countless hours of playing the 'mech games to good use by utilizing the strategies I use in those in the story! Whooo!

ON a side note, does anyone know the origin of Geass? And no, I'm not talking in the anime. I'm talking in Celtic Mythology. No? Well, a Geass was a symbol that essentially gave immortality or superhuman powers in exchange for a code that the bearer had to follow. For example, Cu Chullain (koo-hoo-lin) could not eat meat, or else he'd become mortal again. That's how he died in the Mabinogion, I believe. He was tricked into eating meat by someone since it was courtesy to do so blah blah blah. I'm paraphrasing here, so feel free to look it up and chew me out if I'm wrong in the slightest. I probably am, but at least I started your thoughts, no?

Ok, on with my quips about the anime. How is Suzaku so much better at piloting a knightmare the very first time ever, when Lelouch had been piloting the Ganymede at Miss Silly Milly's crazy festivals for who knows how long? And who's to say that he couldn't have had training as a child? Personally, I don't think one has to be all that fit to pilot a knightmare with great proficiency… Though in order to survive ejection or obscene amounts of damage with good prospects of getting back up immediately after it might be recommended.

Now, story summary: What if Lelouch had seized the opportunity before he acquired Geass to commission and construct a personal KMF of his own? What if he was a better pilot? (Which I think will save his ass.) AND what if it was stored conveniently in a warehouse in the Shinjuku Ghetto where the whole thing started…? Well, for one thing, combat data, that's certain. Also, he could stick it to Suzaku for once in his goddamn life where he hasn't before. Knightmare Combat. The story starts after he hijacks the Sutherland and shortly after the Lancelot launches sortie…

Shinjuku Ghetto, Warehouse District

"I need to get to 'it'…" A nervous Lelouch thought. "They won't stand a chance in hell without it!"

Lelouch was speeding towards a nearby warehouse where he had a special toy awaiting deployment. Sure, he could have waited to use it beforehand, but why let Clovis (and by extension, Britannia) keep the advantage that they did in the form of that white Knightmare? And even though it's only Fourth Generation, that's what upgrades and updates are for.

"It's come to this, then…" Lelouch stated to no one in particular as he pulled into the warehouse. In the center, was a knightmare covered in a cloth, hooked up to a gantry.

"Cu Chullain…" Lelouch said, proud of himself. He DID after all create the Scathach operating system that would allow him to rule the battlefield in the intelligence and communications department. And the thought of the main weapons system had him chuckle.

"Nothing will be able to survive a hit from a fully charged Gae Bolg salvo." Lelouch said, again, to no one in particular as he climbed the gantry to the machine, the cloth long having been hoisted out of the way by a switch he had pressed. It was an impressive looking machine, though slightly ungainly. It was white and black, with a large torso and large shoulders, and the back was extended farther than other KMFs. It's large torso housed enough electronics and computer hardware to put an espionage/ weather satellite to shame.

In the massive shoulders was where the Gae Bolg cannons had been installed, the particle intake fans located on the back of the left and right torsos respectively. The head was relatively low in profile, as it contained important sensors other than the standard factspheres that KMFs came with nowadays. Biosensors, Thermal Sensors, and Electromagnetic sensors to name a few.

The torso tapered of relatively sharply to a narrow set of hips, with slender legs, the landspinners safely hidden away within the three toed feet of the machine. While likely not as fast as the White Knightmare, it was fast enough to deal with Sutherlands and Gloucesters, and future upgrades will be able to fix that. Overall, the Cu Chullain was an intimidating machine, though deceptively agile when need be.

Lelouch had opened the cockpit hatch in the back, getting into the Knightmare. He idly noted how different the instrument clusters were in comparison to the Sutherland that he just got out of (i.e. the number of them). The Cu Chullain is a command center Knightmare, with emphasis on communications, radar, information retrieval, hacking, ally target assistance, (it can paint targets for other KMFs with the Scathach OS, and vice versa.) and a 3 Dimensional Dynamic Tactical Map.

Unfortunately, the knightmare was woefully underequipped for what it was about to do. The Chaladbolg blade was mounted in the right arm was not 100% completed, but would have to suffice, and the Gae Bolg hadn't been fired in real combat scenarios or on a large scale due to the need for secrecy, and are most effective in artillery mode; where the machine will root itself to one spot for stability, reconfigure it's arms and shoulders and finally charge up the lethal long range particle beams.

Lelouch could still fire the Gae Bolg in close combat mode, but there is a limited number of times they can be fired at a certain charge within a certain time, since the particle fans take a small time to recharge. That, and the heat generated by the weapon is astronomical.

The slash harkens were ready to go, and he could just grab the gun that the Sutherland he rode in with has and start rolling off. The Vulcan that was built into the left wrist will likely not be effective against any heavily armored targets, but still nice to have sitting there, nonetheless.

Lelouch entered in the passcode, and started flipping the switches to turn on the Hound of Chullain (That's what Cu Chullain means) to nip at his brother's heels, or better yet, rip him to shreds. It had not yet been tested in real combat scenarios before, and even the tests that had been performed were small scale.

"Well, there's no time like now." Lelouch said, flicking the switch to open the warehouse doors. He put on his headset and looked through the IFF signatures that were still left on his side. Lelouch had already input all of the Sutherland's data while powering up, so this was no problem for the Scathach OS to do. "All survivors! Report!"

"Ka—Q1 reporting…! Where the hell have you been? We're being slaughtered by that thing!" A spunky female voice answered. "We've managed to go into hiding from that white monster, but NOW we can't escape!"

"Do not worry. I have retrieved my trump card for this situation. This will be it's first test. Do you see my IFF in the warehouse district?" Lelouch said. 1 mile away, in her red Glasgow, Kallen nodded. "That is me. Please do not move or make yourselves known in any way unless I order to do so. Understood?"

"Uh… Yeah, sure." Kallen answered, unsure. The other members of the resistance were reluctant to totally agree, but did so anyways. The voice that had almost totally ensured their victory up until this point hadn't been wrong until that white knightmare had shown up, and if he says he can do something about it, why not take that chance anyway?

Lelouch in the Cu Chullain stepped out of the warehouse, testing the radar and the DTM to see how quickly it would gather the data from the map. The sensors were also picking up everything from ambient temperature, Bariatric pressure, wind speed and direction, ambient light, atmospheric density fluctuations, to even humidity. Satisfied, Lelouch activated the landspinners and went for the nearest Sutherland on the radar.

Clovis' forces

"This is Geoffrey Squad. All cl--- wait, what is that?" A Sutherland pilot yelled over radio, upon seeing the unfamiliar frame approaching at high speed. "I can't hold it—UWAAAAGH!"

"Bartley, what just happened?" Clovis demanded. "All the opposing forces are either in hiding or destroyed! And I know for a fact that Lloyd's toy is not responsible!"

"I-I have no idea, y-your highness…" The fat, bald general Bartley stammered. "It isn't even showing up on any IFF channels…"

"Hmph. Almost as if it doesn't exist…?" Clovis concluded.

"Yes, your highness."

"Show me the camera feed, if there is any." Clovis ordered.

"Right away, Prince Clovis." Bartley scrounged the visual data that could be recovered in time, whilst Clovis looked on in his standard pose when he is bored/ waiting for an answer. Eventually, whilst more of Clovis' forces were dropping like flies, Bartley stumbled on a video that had a glimpse of the mystery assailant. Clovis immediately dropped his glass in shock.

"Th-there's no way… It can't be…!" He shouted, standing up. "I recognize that frame!"

"What?" Was Bartley's eloquent reply.

"That's my little brother's Knightmare! He was designing it, but then…" Clovis trailed off sadly.

"I have no idea HOW it came into their hands, but I will not allow Lelouch's memory be treated like that! Lloyd!" Clovis yelled in rage.

"Yeeeees, your highness….?" Lloyd responded.

"Order your Lancelot pilot to destroy that… That… Abomination!" Clovis ordered hysterically.

"Right away, your highness!" He answered cheerfully, before running off. "Ohhhh, Suuuzaaakuuu!"

"I want video feed on the battle, Bartley!" Bartley had no choice but to comply, his prince having since long ago lost his composure.

"Hm… I believe I'm doing quite well with these Sutherlands, even though technically they are the same generation…" Lelouch said, proud of his design. Then he noticed a blip on his radar moving in his direction quickly. "Well, it's do or die time, I suppose!"

The Cu Chullain's shoulders opened up a small bit, and the fans on the back whirled faster, drawing in a luminescent white-blue cloud of particles. Figuring that should do, he popped off a blast from the twin Particle Cannons. Two streams of the same colored light as the particles flew in the direction of the charging Lancelot at extremely high speed. Suzaku was taken by surprise, as he was just going in a random direction looking for the unknown KMF, and because of that, was unable to dodge. The shot from the right shoulder missed completely, but the left one nailed the Lancelot's left forearm dead on, disintegrating the outer shell and some of the internal mechanisms, effectively crippling that arm.

"What the hell?" Suzaku exclaimed.

"NOOOOOO! IT HURT MY PRECIOUS LANCELOT!" Lloyd cried in despair. "SUZAKU! KICK IT'S ASS!"

Clovis was in a different state of thought altogether…

"That was… The Gae Bolg…!" He realized after a moment. "Not only was the apprearance stolen… But it seems the weapon schematics were as well!"

"Eh…? What's the Gae Bolg?" Lloyd asked, curiosity piqued.

"It was a weapons system designed by my little brother, Lelouch." Clovis explained, sighing. "It utilizes charged air particles that have been agitated and released in semi-stable blasts. Because of the fact that it uses matter to fire, those shots have mass…"

"Hm… Interesting… Maybe I should look into that sometime." The crazy scientist mused.

"No need. I'll have to create a charged particle generator for you when this is over." Clovis waved off. "Lelouch demonstrated the concept for me on a small scale when he was 10, a few weeks before…"

"Lloyd! I'm having problems down here!" Came Suzaku's voice through radio.

"Hah. You're quite skilled, but apparently have little KMF experience…" Lelouch said to himself. The Cu Chullain slid out of the way of a slash harken from the Lancelot, returning fire with the left wrist mounted Vulcan, shots bouncing off of Lancelot's plating. Suzaku returned fire with a rifle he managed to snag near a downed Sutherland. Even with the Lancelot's superior speed, the Cu Chullain managed to slide through the rounds heading its direction in a serpentine path, leaning when necessary. Even though the rounds wouldn't do much thanks to Cu Chullain's superior armor, he still didn't want to have any unneeded damage sustained.

"What's with this guy? I can't keep up!" Suzaku growled, clearly frustrated. "I know Lancelot is superior, but this guy is way out of my league as a pilot!"

The Cu Chullain's Chaladbolg popped into place, glowing the same color as the charged particles from the Gae Bolg, and using a move that his mother would be proud of, Lelouch dodged every shot, strike, and made the lunge….

"PRIVATE KURURUGI! DUCK TO YOUR RIGHT IMMEDIATELY!" Came the urgent voice of Clovis. To be honest, everyone was surprised at the Prince's outburst, but Suzaku obeyed on impulse. Watching from the command ship, Clovis' mind was in full gear. Suzaku dodged the lunge with few feet to spare, the Chaladbolg having completely severed the Lancelot's already crippled left arm from the elbow down.

"Now, Private Kururugi, retreat immediately! There is nothing to gain from this battle anymore! All other units, retreat as well! We are leaving!" Clovis announced.

"B-b-b-but Prince Clovis…" Bartley stammered, aghast.

"I should have seen it before. I thought those moves looked familiar…" Right then, the video phone notification next to Clovis rang. Clovis knew who it was. "All of you, please leave this room. This is a conversation I need to have alone."

Though confused, Clovis' subordinates and the ever-loving Earl of Pudding filed out of the command center, leaving the blonde man alone. Seeing that everyone was gone and the room was totally secure, he brought the call up on screen.

"Hello, Lelouch." He said simply.

"Hello, big brother. However did you know it was me…?" Lelouch asked innocently.

"Your moves. Commanding AND piloting." Clovis answered. "You always did beat me at chess and Knightmare duels…"

"That's true, brother. And it seems the tradition continues, no?"

"Where have you been…? We all thought you were dead! Euphie, Cornelia, Odysseus, Schneizel, and I were struck with grief!" Clovis asked, a tear forming at the corner of his eye. "Why?"

"Britannia will fall, brother. Father--- no, that Man will pay for his crimes…" Lelouch answered venomously. "And while I'm glad you and the others actually cared, it matters little."

"How is Nunnally…?" Clovis asked, changing the subject.

"The same. Just as innocent as ever. I can never lie to her smiling face…" Lelouch answered. "How are the advisors doing, making your life difficult?"

"An excellent job…" Clovis sneered. Just the thought of those manipulating bastards made him want to strangle someone. "I suppose you are going to kill me now, since I know your identity. You could easily do it with the Gae Bolg."

"No." Lelouch said. "I won't. Doing something like that would make me like our father, and I refuse to be like him."

"So, what are we going to do then…? Perhaps a chess match? Or I could see Nunnally…?"

"Perhaps… However, you must not tell our brothers and sisters, or anyone for that matter of our survival." Clovis sighed in defeat. He really did want to see the faces of Euphie, Cornelia and Odysseus when they found out that their favorite siblings were still alive. Well, Odysseus was a kind man in general who loved his family regardless of their traits and would be happy to see them survive, even if they were despicable children, but that's despite the point.

"Agreed." Clovis said. "Will you at least tell Euphie or Cornelia if they come out here? And what about Jeremiah? He was absolutely dedicated to your mother… Still is, in fact. If he knew that you were alive, I'm sure he would have no problem swearing allegiance to you, and he would probably quit that blasted purist faction of his."

"Where is he? Please bring him in." Clovis smiled a little, and reached for the personal phone.

"Please send Jeremiah Gottwald to the command center immediately." He ordered. A few minutes passed, the two exchanging pleasantries. Then came Jeremiah's knock and voice. Clovis ushered the confused margrave in quickly.

"It's been a while, Jeremiah."

"Th-that… My lord!" Jeremiah exclaimed, immediately bowing. "I'm so glad to hear that you are alive! Is Nunnally alive?"

"Yes she is, however she is blind and paraplegic."

"While that is a pity, I'm so relieved that both of you are alive!"

"Jeremiah, you realize what is going on in this room stays here, do you not?" Clovis asked sternly.

"Of course, your highness!"

"Excellent, you are dismissed for the time being. We will work out an appropriate time for you to visit little Nunnally in the future. I'm sure she'd be glad to see you again."

"That would be fantastic, your highness!" Jeremiah exclaimed with glee not hidden in his face. He saluted the two princes and took his leave quickly.

"Now, Lelouch..." Clovis started. "What of the terrorists...?"

"Oh, them? I sent them home shortly before I sent my little howdy-do..."
