** It has its own tropes page, [[FanFic/ZeroVsKira here]].

* ''Synopsis'': “Welcome to Fate/Nightmare Apatheia. Welcome to the war.” A deceptively simple crossover between ''Code Geass'' and ''VisualNovel/FateStayNight''. The Holy Grail War becomes the deciding element in Charles’s [[spoiler: and the Grail’s]] plans for {{Instrumentality}}, leading to a guaranteed GambitPileup revolving around Servants and Immortals. One of each falls into the hands of two Ashford Academy students, Servant Saber for Shirou Emiya and the Immortal C.C. for Lelouch Lamperouge. With both Servants and Immortals scattered throughout the world, the Holy Grail War is escalated to a global conflict, promising a new release to Angra Mainyu, All The World’s Evil.

* ''Synopsis'': Set in an altered ''Code Geass'' universe with ''VisualNovel/FateStayNight'' elements mixed into it, this fic tells the story of the most recent Eden Vital War, a ritual established to minimize damage in resolving disputes between Code-bearers with different visions for the future of the World of C, since the last dispute resulted in a world-spanning war that destroyed Atlantis and nearly caused {{The End Of The World As We Know It}}. But, as the cast of Code Geass isn't exactly known for following rules, V.V. decides to stack the deck by sealing away C.C. before the War in order to prevent her from stopping {{Instrumentality}}. C.C. does not take kindly to this, and upon her release during the Shinjuku Incident, appoints Lelouch as the 8th champion of the War - Avenger, the wielder of Absolute Retribution.

* ''Synopsis'': An Manga/ElfenLied / CodeGeass CrossOver. Lelouch first met Lucy when they were ten years old--a meeting that he no longer remembers. He's remained in the royal family ever since. Seven years later, they meet again in Area Eleven just as Lelouch is about to launch his bid for the throne...

* ''Synopsis'': '''Spoilers''' [[AlternateUniverseFic AU]], takes place after all three series. When Lelouch returns as a Code Bearer and encounters [[Manga/DeathNote a young man being chased down by the police in a warehouse district]] of Area 11 he knows his luck hasn't changed. Meanwhile [[MobileSuitGundam00 Setsuna and the rest of Celestial Being]] are watching the events unfold with keen interest.

* ''Synopsis'': This one is a crossover between Anime/CodeGeass and Literature/KaraNoKyoukai, in a world where hidden powers lie just beneath the surface, with a more comprehensive system of supernatural abilities replacing Geass - magecraft, psychic abilities, and even demonic abilities all drawn from the work of Kinoko Nasu's. In other words, its a Code Geass / {{Nasuverse}} fic, with the story of the Black Rebellion set against the backdrop of the Nasuverse itself. Characters from ''VisualNovel/{{Tsukihime}}'', ''VideoGame/{{Melty Blood}}'', and ''VisualNovel/FateStayNight'' as well as from KNK also appear in the story and have roles that affect the plot in some shape or form.
