History Foil / BigHero6TheSeries

** Their possible (one-sided?) ShipTease also seems to serve as one to Hiro and Karmi.

* Karmi interest in germs and pathogens -- which can hurt people -- contrasts with Hiro, Tadashi, and Baymax's focus on healthcare and rescuing people.

* Robert Callaghan and Alistair Krei are explicitly set up as foils at the expo, with Krei wanting to profit off of Hiro's invention and Callaghan trying to persuade Hiro to use his talents for something more. This sets up the reversal when it's revealed that Callaghan is actually Yokai.

* [=GoGo=] Tomago to Hiro Hamada. She is shown to be a natural superhero, especially with her high morals as she is the first one to leap on Baymax to try and stop him from killing Yokai.

''WesternAnimation/BigHero6TheSeries''
* Hiro and [[spoiler: Yokai/Callaghan]]. Both are genius inventors who lost a loved one and most of their actions in the film were driven by their grief and need for revenge. However, whereas Hiro learned to see the error in his actions and accept his loss, [[spoiler: Callaghan]] was too mad by their grief to change and refused to let go of their bitterness. Also, Hiro was surrounded by friends and family who supported and helped him get through his depression while [[spoiler: Callaghan]] kept their pain private and didn't tell anyone.

* Megan Cruz to Karmi and Trina Aken. All of them are female acquaintances to Hiro, are around his age, and have had ShipTease with him. Karmi is his [[TheRival rival]] at SFIT and [[{{Tsundere}} despises him]] (except for [[LovesMyAlterEgo his alter ego]]) and Trina is what Hiro would've been like if he had stayed in bot-fighting and also turns out to be a villain and [[DaddysLittleVillain Obake's "daughter"]]. As for Megan, she's [[TheEveryman an ordinary girl]] who has no problem getting along with him and the two hit it off pretty well and become friends. Unlike Karmi, she is a threat to Hiro's superhero life rather than a source of help to it, but unlike Trina, the threat is of [[IntrepidReporter a good-natured variety]] rather than a villainous one.

** [=GoGo=] Tomago to Hiro Hamada. She is shown to be a natural superhero, especially with her high morals as she is the first one to leap on Baymax to try and stop him from killing Yokai.
** [=GoGo=] Tomago to Wasabi's overcautious driving skills; her readiness to pick up the speed in car chases sharply contrasts with his safe driving instincts.
** Whereas Baymax is quiet and built to help heal people, Mini-Max is bombastic and built to prevent as much property damage that Fred could cause.
** Megan Cruz to Karmi and Trina Aken. All of them are female acquaintances to Hiro, are around his age, and have had ShipTease with him. Karmi is his [[TheRival rival]] at SFIT and [[{{Tsundere}} despises him]] (except for [[LovesMyAlterEgo his alter ego]]) and Trina is what Hiro would've been like if he had stayed in bot-fighting and also turns out to be a villain and [[DaddysLittleVillain Obake's "daughter"]].

Unlike Karmi, she is a threat to Hiro's superhero life rather than a source of help to it, but unlike Trina, the threat is of [[IntrepidReporter a good-natured variety]] rather than a villainous one.
** Megan Cruz to Hiro Hamada. Megan is a normal 14 year old kid with interests, attends high school and loves to have fun. Hiro never got to live a normal life due to being a ChildProdigy growing up and being a superhero in the present day. He also doesn't do activities outside of school, his internship at Krei Tech and superhero missions, making him wonder if he misses out on being a normal 14 year old kid.
** Robert Callaghan and Alistair Krei are explicitly set up as foils at the expo, with Krei wanting to profit off of Hiro's invention and Callaghan trying to persuade Hiro to use his talents for something more. This sets up the reversal when it's revealed that Callaghan is actually Yokai.
** Grace Granville to Robert Callaghan. While Callaghan was generally lax and seemed to be a ReasonableAuthorityFigure, Granville is more no-nonsense. But while Callaghan ultimately succumbed to his own anger and ended up not caring for any of his students, Granville is only tough on her students because she wants them to be at their best.
** Karmi interest in germs and pathogens -- which can hurt people -- contrasts with Hiro, Tadashi, and Baymax's focus on healthcare and rescuing people.
** Diane "Di"/Liv Amara to Alistair Krei.
*** Unlike Krei, Amara is passionate about her scientific work, worked hard to get to where she is, and is generous and willing to help people, even if she may be a bit oblivious and does seem to have an ulterior motive. Krei, on the other hand, is a businessman and not scientist and leaves the work to his disgruntled employees, and can be a CorruptCorporateExecutive that doesn't care about what happens to people unless [[EverybodyHasStandards it gets really bad]], either because [[JerkWithAHeartOfGold he has a sense of decency]] or [[PragmaticVillainy doesn't want to get in legal trouble]].
*** Interestingly, thanks to CharacterDevelopment, Krei started as TheLoad and a blackmailing bastard and slowly revealed himself as a JerkWithAHeartOfGold with HiddenDepths that becomes an ally to the team. While Liv [[BitchInSheepsClothing looks nice at first]], but is actually [[CorruptCorporateExecutive corrupted]], [[TheSociopath sociopathic]] and the [[ArcVillain main villain of Season 2's first arc]].
*** Additionally, Liv Amara tends to be dismissive (as shown by her KickTheDog moment below) towards those who don't share their area of expertise while Krei tries to be approachable to anyone of any talent.
*** Their possible (one-sided?) ShipTease also seems to serve as one to Hiro and Karmi.
*** There's also the way they treat their interns. At first, Krei sees Hiro as a MouthyKid [[NotNowKid he doesn't want to deal with]], but their relationship evolve into a mutual respect, with Krei acting almost like a father to Hiro. As for Liv, she acts like Karmi's best friend, [[FalseFriend but it's all an act]]. She couldn't care less about her, manipulates her, uses Karmi's inventions for her own goals, is ready to kill her [[HeKnowsTooMuch if she gets too close of her plans]] and finally [[spoiler:mutates her and forces her to attack Hiro]].
** Diane "Di"/Liv Amara to Karmi.
*** Both are [[BitchInSheepsClothing [=two-faced=]]] in different ways. Karmi's "nice girl" act was only in front of Granville to annoy Hiro, and dropped it by "Failure Mode". As for Liv, she gives herself a nice mask in public only to hide how monstrous she truly is. Also, CharacterDevelopment turns Karmi into a JerkWithAHeartOfGold, while Liv becomes more immoral and villainous as episodes go on.
*** Both are passionate about their scientific work and would rather not interact with people if they aren't interested in that same passion. While both biologists, Karmi has a strong sense of morality by how she was ready to work in a basement with Orso Knox on the loose to ensure that he gets cured, and also by how she cares about Hiro's well-being despite not getting along with him. As for Liv, she has no sense of morals, doesn't care about the consequences of her actions, and is even ''thrilled'' to commit them.
*** They also seem to be a bit oblivious about how their male counterpart feels about them, with Amara being unaware of Krei's envy of her and Karmi being unaware that Hiro, a boy she sees as her rival, is the hero she crushes on. Both Krei and Hiro also express immaturity when talking about their female counterparts as well.
** Chris appears to be one to Globby. Just like Globby, Chris is a henchman of the BigBad, who's simultaneously competent ''and'' FunPersonified. But while Globby committed a HeelFaceTurn and helped the team defeat Obake in the Season 1 finale, Season 2 has Chris being [[UndyingLoyalty loyal to Liv to the end]]. It's justified since he ''is'' Liv's creation, after all.
** Similarly to Di, the real Liv Amara also one to Karmi. Both are the loner type and biotechnology prodigies. However, Liv is what Karmi would've become if she didn't learn to trust people; while Karmi started as a loner and eventually opened up to people and made friends, Liv only relied on herself (literally) and ended up creating an unstable clone who broke the law repeatedly and put innocent people in danger, who in the end only ruined her reputation.

*** Both are passionate about their scientific work and would rather not interact with people if they aren't interested in that same passion. While both biologists, Karmi has a strong sense of morality by how she was ready to work in a basement with a feral monster Knox on the loose loose to ensure that he gets cured, and also by how she cares about Hiro's well-being despite not getting along with him. As for Liv, she has no sense of morals, doesn't care about the consequences of her actions, and is even ''thrilled'' to commit them.
