An all too common contrast made in an array of works is between intelligence and physical strength. Characters will wholly embody one at the expense of the other (Dumb Muscle, Dumb Jock, The Brute, Nerds with the stereotypical Geek Physique, and Evil Genius) or will be defined by how much they embody one over the other in a group (The Smart Guy or The Big Guy). Oftentimes, such characters will be directly contrasted and used as Foils for one another as in Brains and Brawn or in Beauty, Brains, and Brawn. Creators also tend to impose morality onto the contrast, producing Brains Evil, Brawn Good, building off of Dumb Is Good.
This contrast can even take on gendered forms since women, as "the fairer sex," are considered to be physically weaker than men, giving us the trope Women Are Wiser. Strong Girl, Smart Guy subverts these gender expectations, but still enforces this trope by continuing to uphold the separation between strength and intelligence. Outside of gender, you can see this contrast applied to entire races and civilizations in fantasy settings and science fiction. Many versions of the classic Elves Versus Dwarves dynamic include depictions of elves as a lofty, high-minded, intelligent race and dwarves as physically strong and Book Dumb. Warrior vs. Sorcerer works similarly, with warrior corresponding to brawn and sorcerer corresponding to brains as Magic Is Mental.
Given this portrayal of the two traits in competition or incompatible with one another, using this trope as the basis for conflict is extremely common to the point that entire genres rely on it. This is the reason why elves and dwarves often don't like each other, the Barbarian Hero's main antagonist is the Evil Sorcerer, why many a Superhero's archenemy is an Evil Genius, and why The Bully of Nerd characters are typically Jerk Jocks. The conflict can be within a race or society as well if there are any born unlucky enough to not inherit the desired trait or as part of a Klingon Scientists Get No Respect plot. Battle of the Sexes stories may use this trope to further emphasize the gender divide.
In video games that use some version of The Six Stats to balance playable characters, there will typically be options in which strength is sacrificed for intelligence, wisdom, and/or dexterity and intelligence is sacrificed for strength and/or constitution. If character upgrades are done by the game itself, then expect the bias to become even more extreme, emphasizing this point further. And some games place limits on how much EXP you can put in either stat if the base character selected is of the "opposite" type.
In fact, this trope has been played with and deconstructed so much over time that it spawned a variant to reconstruct it, in which smart characters are portrayed as being agile and strong characters are portrayed as Street Smart. Reflecting their quick-thinking, smart characters use their speed and nimbleness to stay two-steps ahead of their physically stronger opponents while Book Dumb strong characters use their pragmatism to outwit smarter ones, who may only be able to think in the theoretical and not the practical or are prone to missing obvious solutions due to a preference for convoluted logics and plans. When applied to fighting, this variant tends to overlap with Force and Finesse.
As a Super-Trope to several different tropes about the depiction of strength and intelligence in media, relegate specific examples to their proper subtrope pages whenever possible.
- Bungo Stray Dogs: Dazai and Chuuya were partnered together as teenagers as part of the duo, Double Black, and have always loathed each other. Chuuya is a massively powerful Gravity Master and an excellent martial artist responsible for carrying out the physical aspect of their missions, usually by killing people. Dazai, on the other hand, is absurdly intelligent and manipulative, able to unfailingly come up with the perfect plans Chuuya executes. However, despite his strength, Chuuya always finds himself under Dazai's thumb and begrudgingly admits his intellect is indispensable.
- Digimon Data Squad: Marcus and Thomas have this dynamic. Marcus is a Hot-Blooded street fighter whose approach to every problem is to hit it harder. Thomas is a Teen Genius tactician who prefers to think things through. Naturally, the two butt heads frequently throughout the series.
- This is everywhere in Dr. Stone. The three main protagonists of the series, Senku, Taiju, and Yuzuriha make up a Beauty, Brains, and Brawn trio. Even before the world effectively ended, Senku and Taiju were a Brains and Brawn duo since they were childhood friends. The main antagonist of the first arc is Tsukasa who decides to oppose Senku's idealized Kingdom of Science by creating and leading the Empire of Might, hoping to keep a low-tech and therefore egalitarian world in order to avoid the creation of weapons of mass destruction and warfare. He is later dethroned by Hyoga (for a while), who is a more straightforward Social Darwinist.
- Durarara!!: Izaya is an intelligent and well-read information broker who has a mutual hatred with Shizuo, a debt collector with inhuman strength who can shake off being hit by a car. In the final arc, the two have an all-out death battle, pitting Izaya's brain against Shizuo's brawn, as the former uses traps and schemes to kill, and the latter simply comes after Izaya with nothing but his fists. The fight culminates in Izaya attempting and failing a Xanatos/Thanatos gambit and neither die.
- In Maoyu, the Hero is a Country Mouse who became a nigh-unstoppable One-Man Army thanks to being The Chosen One and his constant training. Meanwhile, the Demon Queen is a scholar who spent most of her days prior to ascending to the throne reading and performing experiments. When Hero confronts her at the start of the story, she admits that she's probably no match for him in a fight, instead asking for his attention and challenging his worldview with a presentation on the impact of the human-demon war from an economic standpoint.
- Captain America is at the peak of human athletic potential and is a master combatant and leader, but typically leaves things like handling technology to his allies. His archenemy Red Skull may or may not have the same or similiar abilities depending on the story, but is usually a Diabolical Mastermind.
- The Incredible Hulk: The titular (Savage) Hulk (big, green, Dumb Muscle, The Big Guy) and one of his main archnemeses, The Leader, (tiny, green, Evil Genius), as he is a deliberate Evil Counterpart to the Hulk. The Hulk's true identity, Bruce Banner, is a skinny scientist who gains Super Strength from gamma rays whereas The Leader, Samuel Sterns, was a borderline mentally handicapped janitor who gains Super Intelligence from gamma rays.
- The Hulk as Bruce Banner's Split Personality also qualifies since he is contrasted with Bruce Banner, who is an Insufferable Genius in the running for World's Smartest Man. You could say that all of the different personalities Banner has plays with this trope to some degree. Though all of them are, relative to the average person, far closer to Strength than Intelligence due to their shared Super Strength and Nigh-Invulnerability, some personalities (Merged Hulk, Grey Hulk) skew closer to the center of the spectrum, inheriting Banner's Book Smarts or developing Street Smarts, and others (Devil Hulk) lean even further into The Hulk's strength.
- The Mighty Thor: Thor and Loki have this dynamic, overlapping with Brains Evil, Brawn Good as Loki is Thor's Arch-Enemy in his comics. The God of Thunder, Thor has Super Strength and when he's not using his mastery over thunder and lightning to Shock and Awe, he's a Lightning Bruiser whose physical strength rivals that of the Hulk. Loki on the other hand is a Trickster God, who uses his vast intellect to trick anyone and everyone into one of his many gambits and schemes.
- Superman has this dynamic with his archnemesis Lex Luthor, which as one of the oldest superhero comic book franchises, did a lot to codify this dynamic in the medium. While Superman isn't shown as being particularly dumb, his Flying Brick superpowers definitely focus on strength and durability (Super Strength, Nigh-Invulnerability) which help him be a combat powerhouse. Lampshaded in his nickname "The Man of Steel." Lex Luthor on the other hand is a Mad Scientist, Diabolical Mastermind, Evil Genius who uses his vast amount of wealth as a Corrupt Corporate Executive to try to make his usually nefarious plans into reality.
- The Mountain and the Wolf: Discussed. The Wolf mentions that while there are some individuals who combine brains and brawn, for the most part practitioners of magic are very much Squishy Wizards, and so the person Tyrion is looking for (a man masquerading as Euron strong enough to kill several guards singlehandedly then stuff their bodies into a windlass) is not the one who cast the spell that caused Daenerys to attack King's Landing. And the Wolf certainly should know, seeing as he's the one who masterminded both events via a Champion of Chaos and a sorcerer.
- The Lion King: Cited by Scar when Zazu asks him why he doesn't challenge Mufasa for the throne. While Scar claims to have gotten "the lion's share" when it comes to intellect, a fight for supremacy is a matter of brute strength, where Scar is "at the shallow end of the gene pool." While gauging which brother is smarter would be subjective, it's clear Scar is more devious and guileful, in that he engineers his brother's demise to attain kingship of the pride. However, it's subverted when we see that after Scar takes control, he turns out to be a terrible leader, leading Pride Rock to ruin.
- In Megamind, this dynamic is present between the titular character who is an Evil Genius and his nemesis Metro Man, a Flying Brick, as an Affectionate Parody of the same dynamic Lex Luthor and Superman have. As a deconstruction of that particular relationship this is to be expected. Later on, after the latter fakes his death, Megamind invokes this trope by replacing Metro Man with Titan as his new superhero archnemesis, bestowing him all of Metro Man's Flying Brick powers to do so.
- Captain America: The First Avenger: Johann Schmidt (Brains) vs. Steve Rogers (Brawn). Both are Super Soldiers created from the same Super Serum, and fight on opposite sides of the war, with Schmidt being a brilliant scientist using advanced technology who works from the shadows, while Rogers fights on the frontlines using a shield.
- This is a popular theme for game shows, specifically team-based challenge-type shows:
- The 8th season of Australian Survivor is subtitled Brains V Brawn, enforcing this trope by splitting the contestants up into two teams based on their supposed intellect and strength.
- The sixth episode of Season 6 of the physical challenge show Wipeout (2008), "Brains vs Brawn", pits contestants with "brainy" jobs against professional bodybuilders and other highly athletic people.
- The Dad's Army episode "Brains Versus Brawn" makes this trope the primary conflict. Jones and Walker get upset when they learn that the Training Major left out their platoon from training a new unit of commandos. Mainwaring backs the division arguing that commandos use brute force rather than cunning and intellect so they don't need training from the likes of them. This leads to Pritchard suggesting they run a training exercise competition in which the different troops have to deliver a fake bomb to the Officer-in-Charge's office. Brains win out in the end, after Walker orders for the delivery of a second fake bomb to the Officer-in-Charge's office.
- Leverage: Hardison is the hacker and Eliot is the hitter. The two regularly fight over a lot of things, but they particularly tend to argue about who has the most important and difficult job. Eliot and Hardison also disparage each other over the other's lack of expertise in their respective fields.
- Power Rangers Dino Thunder: The Leader Conner is a Jerk Jock to Jerk with a Heart of Gold, who often mocks The Lancer Ethan for his lack of interest in athletics while Ethan (The Smart Guy and Black and Nerdy) finds Conner's disinterest in academics to be immature. In "Leader of the Whack", the two are transformed into the opposite of their default personalities, with the implication that on some level, a part of them wishes to explore the opposite of who they present to the outside world.
- In the Squid Game episode "Stick to the Team", this is how the second round in the tug-of-war game ends up starting, with Gi-Hun's weaker team relying on tactical knowledge to have a chance against their stronger, all-male opponents. Il-nam tells them all to pull and lean as far back as possible. The opposing team will struggle in the first seconds before losing their footing, allowing Gi-Hun and the others to gain an advantage. However, when the other team gets a second wind and starts to pull back, Sang-woo forms a alternative plan to quickly defeat them.
- This is often how Athena and Ares are contrasted in Classical Mythology as gods of war. Athena as the goddess of wisdom, represents the strategic thinking and planning that is necessary for engaging in large scale battles, but is also useful from a "fight smarter not harder" standpoint in any context. Ares on the other hand is the god of courage and war, more typically associated with brutality, carnage, and bloodlust that comes with mass killing. From The Iliad's account of the Trojan War, Ares and Athena found themselves on opposite sides, with Ares backing the Trojans and Athena supporting the Greeks. To lessen their battle output, when Ares was fighting King Diomedes, Athena uses an invisibility cloak from Hades to hide herself and causes Ares's spear to miss, opening him up for a counterattack that leaves him wounded.
- In Dino Crisis, at numerous points, Rick and Gail will have heated arguments and Regina can choose whose plan to align with. Gail generally prioritizes brawn, and following him will result in the path that is more simple, but involves much more dinosaur fighting; by contrast, following Rick is safer, but involves solving a lot more puzzles.
- In the Mass Effect franchise, the Krogan are a Proud Warrior Race that prioritizes brute strength, combat prowess, and killing above all else. Might equals right and the weak shall not live long. Thus even the idea of Krogan scientists is enough to make a joke of. You ironically come across one in Mass Effect 2 who is working on a cure for the sterilization genetic virus called the "genophage" that plagues all Krogans, but he is the only one across multiple games. While the Krogan have made many enemies and dislike most of the Council Races, the Salarians have a special place of hate for them as the creators of the genophage. Naturally, Salarians are depicted as the most intelligent and scientific minded of all races in the franchise and are also considered the physically weakest. They compensate as a race by specializing in espionage and covert operations. While individual Salarians have differing opinions on the Krogan, their leader Dalatrass Linron would rather risk the entire galaxy being wiped out by the Reapers rather than cure the genophage in order to win over the Krogans as allies against them.
- Pokémon features several Pokemon types that are advantageous to use against other types, similar to Rock, Paper, Scissors. Psychic type Pokémon have an advantage over Fighting type Pokémon, reflecting the brains beats brawn mindset. Fighting types in turn have an advantage over the Dark type which, contrary to what its name implies focuses on fighting dirty, reflecting the brawn beats brains mindset.
- In The Petri Dish, more intellectual characters such as Thaddeus and Kelvin don't really understand sports, and when Thaddeus tries watching sports, he can't make sense of it despite his intellect.
- Avatar: The Last Airbender: On Team Avatar, Sokka is The Smart Guy, specifically The Strategist who comes up with many of the team's plans for infiltration and escape. He is also the weakest for the majority of the series in terms of combat capability as the primary sole non-bender of the team. He is contrasted first with Katara, and later with Toph. Toph is rude, crude, Book Dumb, and one of the strongest earth benders in the entire Avatar world. Their friendship is portrayed as Vitriolic Best Buds, with Toph antagonizing Sokka most of the time. Over the course of the series we learn that Toph is much more Street Smart than she initially comes off and Sokka learns swordsmanship to compensate, pushing them closer to the second variant of this trope and to Force and Finesse in terms of combat.
- Brandy & Mr. Whiskers: The season 1 episode "Lack of Brains vs. Brawn" plays with this trope when Mr. Whiskers has to deal with The Bully Lester. While Mr. Whiskers is portrayed as being Nerd-ish relative to Lester, Mr. Whiskers is a Cloud Cuckoolander and often The Ditz of the show. However, as Characterization Marches On, in later episodes he becomes more of a Genius Ditz.
- Mummies Alive!: In "Paws", Nefer-Tina is Brainwashed by the cat goddess Bastet who makes her abduct Presley. Ja-Kal and Rath clash over how to resolve the situation; Rath wants to use a spell to free Nefer-Tina and save Presley while Ja-Kal thinks they have no choice but to kill Nefer-Tina. Ja-Kal accuses Rath of being weak and indecisive while Rath berates Ja-Kal for relying too much on brute force.
- The Powerpuff Girls: Blossom and Buttercup can often fall into this dynamic as The Leader & The Smart Guy versus The Big Guy. In "Three Girls And A Monster", Blossom and Buttercup keep arguing whether to defeat the monster of the episode with brute force or well-thought plans. However, neither strategy works giving the sheer size of the monster. What works instead is Bubbles politely asking him to leave the city.
- The season finale of the second season of Thunderbirds Are Go, "Brains vs Brawn'' subverts the trope by having Bollywood Nerd Brains go up against The Dragon only known as "The Mechanic." While he has been causing trouble for the team all season long as The Heavy, The Mechanic is a Gadgeteer Genius and far from dumb, thus making this encounter less of a battle between two Foils as it is between Mirror Characters.
- The season finale of Total Drama: Revenge of the Island is titled "Brain vs. Brawn: The Ultimate Showdown" as the final two contestants are Black and Nerdy Cameron and Jerk Jock Lightning. The season actually has two endings in which one or the other wins, however both win moreso out of luck, than actual skill on either of the brains or brawns side, as the final challenge completely exhausted them. During the actual fight however, Lightning uses a crude weapon and armor and him trying to simply brute force his foe results in several mutant animals getting released into the arena. On the other hand, Cameron designs a high tech suit of armor and outmaneuvers his foe with a lot of quick thinking.
- The Transformers:
- The Technobot combiner Computron is extremely intelligent, able to calculate the most efficient path to victory. His Terrorcon counterpart, Abominus, is sheer animalistic brute force. Their battles usually involve Computron using his intelligence to counter Abominus' savage fury.
- A friendlier version forms the B-plot of the episode "Microbots", in an amusingly literal fashion. The gruff, macho puncher-of-things Brawn thinks that the bookish and generally non-combative researcher Perceptor is of little use in the fight against the Decepticons, and loudly insults him for it. Optimus' plan to reconcile them involves shrinking them and sending them inside a drunk Megatron. (It Makes Sense in Context, honest.) Brawn eats his words at the end when Perceptor demonstrates that his combination of precision, calculation, and skill means he is a formidable sniper.
