A multimedia franchise spawned from the 2006 ''Anime/CodeGeass'' anime series. Created by Creator/{{Sunrise}}, the story is set in an AlternateHistory where Britain had a [[UsefulNotes/TheHouseOfTudor Henry IX instead of James I]], kept America, but lost the British Isles to UsefulNotes/NapoleonBonaparte. They fled to the American colonies and founded the Holy Britannian Empire, which expands to control over a third of the world, particularly after they invent HumongousMecha. Oh, and there are the titular psychic powers involved. The main story focuses on Lelouch vi Britannia, an exiled prince of the empire who becomes the leader of a formidable rebel army fighting against the empire - and his own father, the emperor.

Along with several canon spinoffs, ''Code Geass'' has produced an incredible amount of AllThereInTheManual content, which includes audio dramas, {{Picture Drama}}s and DVD-exclusive short stories that help flesh out the show's universe or expand on its characters. It has also garnered five AlternateContinuity manga and multiple games to date.

%%Leave the redlinks alone.
!!Main Canonical Works:
* ''[[Anime/CodeGeass Code Geass: Lelouch of the Rebellion & Code Geass: Lelouch of the Rebellion R2]]'' -- (2006-2008) The original anime, and the sequel spanning 25 episodes each.
** In addition to the main series, there are also three compilation films that both condense and retell the story as well as add new scenes that act as canonical updates: ''Awakening Path, Rebellion Path'' and ''Imperial Path''.
* ''Code Geass: Lelouch of the Resurrection'' -- (TBA) A continuation of the original anime, announced on November 27, 2016.
* ''Anime/CodeGeassAkitoTheExiled'' -- (2012-2016) A sidestory {{OVA}} written and directed by [[Manga/TheVisionOfEscaflowne Kazuki Akane]]. It takes place between the first and second seasons, focusing on a group of Japanese pilots in the army of the Europia (this world's third great power, unified by Napoleon).
* ''Manga/CodeGeassRenyaOfTheDark'' -- (2011-2013), a prequel manga with a script by Goro Taniguchi and art by Tomomasa Takuma. It follows the story of the eponymous Renya, who encounters C.C. and [[IdenticalStranger a man bearing an incredible]] [[{{Expy}} resemblance to Lelouch]] in Edo-period ([[AlternateHistory or at least its equivalent]]) Japan.
* ''Manga/CodeGeassOzTheReflection'' --- (2012-2015), a SpinOff manga that takes place between the first and second seasons. Written by Shigeru Morita, it tells the story from the viewpoints of two different protagonists, Orpheus Zevon and his sister Oldrin Zevon.

!!Non-Canonical Works:
* ''CodeGeassNunnallyInWonderland'' -- (2012) A 30 minute StorybookEpisode {{OVA}} that features the characters as the cast of ''Literature/AliceInWonderland''. Also acts as a BizarroEpisode of sorts for the entire series because of all the silliness going around providing a contrast to the darker atmosphere that is generally prevalent in the original anime.
* ''Manga/CodeGeassLelouchOfTheRebellion'' -- The most faithful adaptation of the anime, even though it removes the HumongousMecha and most of the military action in favor of more comedy and {{shojo}} elements.
* ''Manga/SuzakuOfTheCounterattack'' -- Skews more {{Shonen}} and focuses on Suzaku rather than Lelouch; it turns the Lancelot into a powersuit and Suzaku into a Franchise/KamenRider-esque superhero.
* ''Manga/CodeGeassNightmareOfNunnally'' -- A vast departure from the normal ''Code Geass''; it focuses on Lelouch's IllGirl sister Nunnally, who becomes a LittleMissBadass in an ''[[Anime/NeonGenesisEvangelion Evangelion]]''-esque mecha and battles similarly-powered girls. (Oh, and Lelouch returns later on to channel [[Anime/MobileFighterGGundam Master Asia]].)
* ''Manga/CodeGeassTalesOfAnAlternateShogunate''/''Strange Tales of the Bakamatsu'' -- A UniversalAdaptorCast story that places the characters in the Bakamatsu era of Japanese history; Lelouch becomes the head of UsefulNotes/TheShinsengumi while secretly opposing the Meiji reforms brought on by Britannia (here standing in for Admiral Perry). More light-hearted than other adaptations/spin-offs, with a semi-[[SuperDeformed chibified]] art style and less melodramatic story elements (Zero and Black Knights, here renamed the Black Restoration Order, basically turn into RobinHood and his Merry Men). Also plays faster and looser with realism; a pizza delivery service exists, even though the manga takes place at a time well before pizza became popularized in America, let alone the rest of the world.

* ''VisualNovel/CodeGeassLostColors'' -- Spin off Visual Novel with the main character called Rai who has lost his memories and has ended up at Ashford Academy. Now Rai must decide how he goes about regaining his memories.
* ''Code Geass: Maelstrom of Libra'' -- A mobile game starring a young girl named Leila who escapes from a research facility in the desert.[[/index]]
