History Foil / CodePrimeR1Rebellion

Code Prime R1 Rebellion has many examples between both human and Cybertronian characters.

* The Decepticons to the Autobots regarding their human allies - while the Autobots tend to be extremely friendly with the Black Knights (to the point that most of the named Autobots have human partners within the Black Knights), the Decepticons prefer to keep their relationship with their Britannian allies strictly professional, [[spoiler:and eventually decide that [[YouHaveOutlivedYourUsefullness Britannia has outlived its usefulness]] and make plans to conquer the empire]].

* Shirley Fenette to Euphemia li Britannia - both are kind, caring woman who are love interests to one of the human protagonists in the story. As for differences, Euphie is a princess while Shirley is implied to be a commoner, and Shirley is mostly uninvolved in the conflict between Britannia and the Black Knights/Autobots [[spoiler:at least at first]] while Euphie tends to be close to the front lines even if she absolutely hates fighting.

* It's lampshaded by the Autobots how similar Lelouch is to Megatron and Suzaku is to Optimus. However, eons of experience have made Optimus a great deal more pragmatic than Suzaku, who is more idealistic and can't yet comprehend that some people just won't change for the better. Lelouch may be similar to Megatron, but unlike Megs, he can feel compassion, empathy, and form strong bonds with others while Megatron is a sociopath that only sees others as tools to achieve his goals. In addition, their origins are almost polar opposite from their comparisons. Lelouch was a Royal Britannian while Megatron was a low-class gladiator. Suzaku is an "11" turned "Honorary Britannian" while Optimus was a high-class archivist.
* While Lelouch and Suzaku were already this in canon, their {{Foil}} status is further highlighted by their interactions with the Cybertronnians leaders on their respective sides - Lelouch completely trusts Optimus and is [[PositiveFriendInfluence slowly becoming a better person because of it]], while Suzaku is [[ProperlyParanoid understandably wary]] of Megatron and has [[SlowlySlippingIntoEvil slowly been corrupted by him]].
* Lelouch has yet another foil in Optimus - both are rebel leaders who came from relatively prestigious backgrounds and have a natural gift for inspiring others with words only. But while Optimus managed to enact the reforms he sought while still maintaining his prestige (and was only forced to become violent when the Decepticons struck first), Lelouch lost almost everything as a child and initially led his revolution out of revenge, [[BecomingTheMask before coming to believe in his own rhetoric]].

* Optimus Prime to Suzaku. Optimus shares Suzaku's idealism, but has it tempered with experience and a better understanding of why conflicts can happen. Additionally, Optimus started out as an archivist (a librarian, essentially) from the upper classes of Cybertron while Suzaku, though born into an influential family, was reduced a second class citizen ''at best'' after his homeland was conquered.

* Suzaku is also one to Megatron as well, as the two of them were low-class inhabitants of a flawed caste system but were able to rise to prominence by recognition of their incredible fighting valor. However, while Megatron rose to command and maintained loyalty within his ranks by making sure they always aware of his superior might, Suzaku is subservient (and by extension, ''much'' more manipulable) and would rather follow commands than issue them.

* Shirley Fenette to Kallen Kozouki - Shirley is calm, emotionally fragile, and wouldn't hurt a fly, while Kallen has quite a temper, has an unbreakable will to fight, and is the best Knightmare pilot among the Black Knights. Despite this, they actually get along very well. Romantically, Shirely is the Betty and Kallen the Veronica to Lelouch's Archie.

* ''Fanfic/CodePrimeR1Rebellion'': A ''Anime/CodeGeass'' and ''Franchise/{{Transformers}}'' crossover.
** Bumblebee finds Lelouch similar to ''Soundwave'' of all bots - both are master planners who pretty much obliterate their competition with well thought out strategies. Lelouch, in turn, upon learning of Soundwave, compares him to both himself and Schneizel. Of course, Soundwave was a low-ranked gladiator in the past while Lelouch and Schneizel were born privileged royals who are anything but fighters.

But while Optimus managed to enact the reforms he sought while still maintaining his prestige (and was only forced to become violent when the Decepticons struck first), Lelouch lost almost everything as a child and initially led his revolution out of revenge, [[BecomingTheMask before coming to believe in his own rhetoric]].
** Finally, Lelouch has one other pronounced foil: Bumblebee. In terms of attire, Lelouch is DarkIsNotEvil while Bumblebee is LightIsGood. Lelouch is a natural-born leader while Bumblebee prefers to follow the lead of others. Lelouch is a talented speaker while Bumblebee is TheSpeechless. Lelouch is a NonActionGuy while Bee is a frontline fighter. Finally, in regards to knowledge, Lelouch and Bee represent intelligence and wisdom - Lelouch is a master planner and manipulator, but can still be caught flat-footed by things he didn't predict. Bee, meanwhile, may not be much of a planner but is well aware of how things can go wrong and warns Lelouch to expect unforeseen consequences.
** Optimus Prime to Suzaku. Optimus shares Suzaku's idealism, but has it tempered with experience and a better understanding of why conflicts can happen. Additionally, Optimus started out as an archivist (a librarian, essentially) from the upper classes of Cybertron while Suzaku, though born into an influential family, was reduced a second class citizen ''at best'' after his homeland was conquered.
** While it has yet to be brought up in the story, Kallen's actually a pretty good one for Soundwave - both are ''extremely'' talented warriors that hold positions of significant importance within their respective organizations. Both also hold special relationships with their respective leaders - [[VillainousFriendship a platonic one for Soundwave]], [[ShipTease a questionably romantic one for Kallen]]. Both relationships are also reciprocated. There's one very pronounced difference, though - while Soundwave downright encourages the worst parts of Megatron's behavior, Kallen brings out the best parts of Lelouch's character. Additionally, Kallen prefers to fight up close, while Soundwave normally uses his Mini-Con army and Groundbridge to deal with foes.
** Suzaku is also one to Megatron as well, as the two of them were low-class inhabitants of a flawed caste system but were able to rise to prominence by recognition of their incredible fighting valor. However, while Megatron rose to command and maintained loyalty within his ranks by making sure they always aware of his superior might, Suzaku is subservient (and by extension, ''much'' more manipulable) and would rather follow commands than issue them.
** Cornelia to Airachnid - both are highly skilled female fighters in their respective organizations with a penchant for melee combat. Other than that, though, the two could not be more different - Cornelia uses a ground-based Knightmare while Airachnid's alt-mode is a helicopter. Cornelia prefers blunt action against her foes while Airachnid enjoys playing with her victims. Cornelia leads her forces while Airachnid prefers to let others do the planning. Finally, while Cornelia [[NobleDemon has moments where she is surprisingly sympathetic]] (such as [[BigSisterInstinct her concern for Euphemia]]), Airachnid [[HateSink is never portrayed as anything other than a monster]].
** Cornelia's also one to her half brother, Lelouch. Both are {{Frontline General}}s, but while Lelouch only leads from the front out of personal morals and is otherwise a lackluster pilot, Cornelia leads the charge because she enjoys battle and is a skilled warrior. Cornelia is brash and aggressive versus Lelouch being calm and collected. Lelouch has only been {{Outgambitted}} exactly ''once'' in the story, while Cornelia has only pulled off a single win. Things have only gone FromBadToWorse for Cornelia, while Lelouch's life has primarily gotten better. Additionally, while Cornelia has suffered numerous defeats yet absolutely refuses to swallow her pride, it took Lelouch receiving exactly one HumblePie from her to realize he needed to start changing for the better. Finally, while both half siblings work with a Cybertronian leader, Cornelia prefers to work professionally with Megatron while Lelouch views Optimus as a ParentalSubstitute.
** Starscream to Airachnid - the two of them are the least sympathetic of the Decepticons, share similar body-types, and have aerial alt-modes. As for differences:
*** Starscream's alt-mode is a jet while Airachnid's is a helicopter.
*** Starscream desires to lead, while Airachnid is willing to follow as long as she can indulge in her sadism.
*** Starscream is a competent planner, but frequently has his schemes ruined by [[DidntSeeThatComing circumstances that could happen, but which he never expected]]. Airachnid, meanwhile, prefers to play things by ear, with most of her loses being due to a SpannerInTheWorks or five.
*** Airachnid left the Decepticons because she wasn't able to indulge in her sadism following the end of the war. Starscream remained so that he could try and become leader.
*** Starscream's actions are usually ([[NotSoHarmlessVillain but not always]]) PlayedForLaughs. Airachnid's actions, however, are ''always'' PlayedForDrama.
** Shirley Fenette to Kallen Kozouki - Shirley is calm, emotionally fragile, and wouldn't hurt a fly, while Kallen has quite a temper, has an unbreakable will to fight, and is the best knightmare pilot among the Black Knights. Despite this, they actually get along very well. Romantically, Shirely is the Betty and Kallen the Veronica to Lelouch's Archie.
** Shirley Fenette to Euphemia li Britannia - both are kind, caring woman who are love interests to one of the human protagonists in the story. As for differences, Euphie is a princess while Shirley is implied to be a commoner, and Shirley is mostly uninvolved in the conflict between Britannia and the Black Knights/Autobots [[spoiler:at least at first]] while Euphie tends to be close to the front lines even if she absolutely hates fighting.
** The Decepticons to the Autobots regarding their human allies - while the Autobots tend to be extremely friendly with the Black Knights (to the point that most of the named Autobots have human partners within the Black Knights), the Decepticons prefer to keep their relationship with their Britannian allies strictly professional.
