Not bad I doubt that the council would go to war over the word of the Batarian hegemony they have bean at odds with them politically and socially for years. The council would investigate before making a move to assist what they consider a borderline rogue state in a war simply on there word. I hope you give the council more credit and intelligence than to have them rush in to this. I am happy that you are utilizing the maneuverability of the Ezo based ships to give them some level of survivability against Britannia's navy instead of simply buffing them outside of cannon well done. Any ground battles with knightmares involved is going to go horribly for Ezo based military the weapons utilized by said KMFs will utterly annihilate anything the council can field on the ground. Britannia's infantry verse Council type infantry will be in favor of Council forces if the Britannia military continues to utilize kinetic chemical propellant based small arms and lacks shielding though there physical armor is probably far superior to that of a MA hard suit that relies heavily on its kinetic barriers for stopping incoming fire and lacks in actual armor plaiting. From what I know of the two universes tech base humanity will have the edge in metallurgy aka actual physical armor considering they can build massive KMFs and the stress on the metal from high speed maneuvering does not tear them apart the alloys available to Britannia must be impressively strong. The Ezo based tech and kinetic barriers that MA ground forces have will level the playing field as far as protection goes for infantry ground engagements that do not involve KMF assets and MA based small arms are superior to anything I am aware of Britannia infantry forces utilizing. Considering the extremely small size of MA small arms projectiles they could have trouble penetrating human infantry armor. For space combat humanity has the edge in short and medium range engagements because of superior shielding and insanely powerful DEWs that can ignore Kinetic barriers and strike at the hulls of the council warships directly. As far as I can tell human blaze luminous shields can take a massive amount of damage before they fail and stop all attacks energy or kinetic whereas kinetic barriers are from what I have observed not nearly as strong unless powered by a truly massive Ezo core and do not stop energy weapons at all. Council forces will do best to keep there distance as much as possible if they do not want to be incinerated and it will be difficult for them to do so because of the large amount of fire it takes to destroy any human ship with shielding thus allowing them to survive as they close the distance all in all navy battles will probably cost council forces heavily because of the mitigation of there primary defense mechanism the kinetic barrier. Guardian lasers will be a unpleasant surprise for KMF pilots you can't dodge a weapon traveling at the speed of light after all. I am very excited to read more of your story this crossover is not done very often and has a lot of potential. I like the idea of this crossover because the two tech bases allow for a actual war and not a complete curb stomp human forces will probably suffer a large but not crippling number of losses. Though human tech is superior in many aspects the absolutely massive size of the Turian navy and military as well as there excellent skills in the art of war will allow for a long and drawn out war not the standard two week long humanity F*** yaa that infects so many MA crossovers that then ends in the stereotypical show of force at the Citadel by humanity.
P.S. does Lelouch have the sky fortress Damocles in your story it should not have bean destroyed and I am wondering if it had bean build in your timeline as well as if the weapon F.L.E.I.J.A. is utilized by there navy that thing would be bad news for any fleet.

This is a good chapter but u need to explain how things went differently in past other then lelouch never was a demon emperor ,
how Cornelia is still alive and why she is working with lelouch. Maybe do a timeline or summarize what happened with humanity before today, like what FTL system they use.

Because while this is good, it's Confusing without background

That was a cool chapter, the FLEIJA being used against the batarians was very interesting. Though are they aware of mechas? I mean, it would be interesting see their reaction when they discover that the bulk of their force would be composed of knightmare frame. It should be remembered that sakuradite is for CG what eezo is for ME, and I guess the supply problem can be contorned by mining in other planets, though I'm interested to know who Lelouch placed at his court, since Cornelia is still alive. Keep going!

Well done, loved it

This is just my theory that when Lelouch share his code to others close to him it will probably make them ageless but not indestructible probably because they only obtain half the code and not the full code like C.C.

Interesting chapter and like how you add the FLEIJA to the ships' arsenals. But it would be nice to know what is going on with Lelouch and how Cornelia is still alive and willing to work for Lelouch. Since he did kill Euphy even if he didn't like it.

I really like it so far its quite an original take on things keep going!

Ah man I can't to see the Turian's faces when they face the Britannians and are you planning on having Cornelia lead the Britannian forces during the next battle cause if you do I can imagine the Turian's horror at facing her.

damn cliffhanger i want more i want to see the reaction of the counsel anyway nice chapter

Just a reminder, the knightmares ran on sakuradite, and the world would have run dry. Not only knightmares, but all the high end tech ran on it. You would need to address this to make the tech they use viable. But still looking forward to the other chapters. If your taking votes for empress, I vote C.C. Her an lelouch deserve each other

Well first make the chapters a little longer, add more details in the places that the characters as in and update soon. I see a good story in this.

this looks good but please do the code geass tech justice the F.L.E.I.J.A makes a nuke look like a firecracker and a dreadnought only has 38 kiloton of TNT per shot firepower the first nuke in 1945 was 20 kilotons. the strongest built was actually built in 1962 and was 600 times stronger that's 12000 kilotons there was never a need to build anything stronger. that was only after 17 years think how fast the code geass tech advanced even if they slowed down after the war their tech level would be insane by now, they already had things the council think are impossible in the anime i do wish it was the turians if only because the batarian's are too easy of a target

Longer chapters please:)

Seems interesting.

INTERESTING START . wonder what space travel they use then .
