When you get knocked down, you gotta get back up
I ain't the sharpest knife in the drawer but I know enough, to know
If you're gonna be dumb, you gotta be tough!
The tendency for strength and intellect to be inversely proportional. The Big Guy and The Brute are usually slightly dim at the very least (with The Smart Guy and The Evil Genius at the opposite end of the scale; incredibly intelligent, but knocked over by a stiff breeze). Typically afflicted with a form of Hulk Speak. This is a common assumption: there's a reason Genius Bruiser is meant to be a shocker. Overlaps with Gentle Giant in some cases, as well as Tiny-Headed Behemoth. A subtrope of Personality Powers. Often Played for Laughs.
Almost Always Male; only in ultra-rare cases will you see very strong female characters be portrayed as lacking in brains. He might be only Book Dumb but Street Smart. Note that this also does not always apply to tactics; a character with this trope might know how to use every weapon he picks up, but if that is true, he will still lack intelligence outside that specialty (in which case he is shown as a Genius Ditz). When this character causes injuries and property damage due to being clumsy with his immense strength, he is Lethally Stupid.

- A series of commercials for Planet Fitness airing in early 2011 play this for laughs. One commercial features a muscular man who gets so excited from tying his shoelaces correctly, he runs into the gym cheering. A second features a man who likes to make gunshot sounds when he writes. A third has a guy who replies "I lift things up, then put them down." when asked what he does for a living, then repeats it without prompting. Each commercial then explains that Planet Fitness is "not his planet".
- Moe from Calvin and Hobbes fits this nicely; Calvin relies on the fact that Moe will not understand any of the florid insults that he (Calvin) heaps upon the bully. Though it doesn't prevent Moe from messing up Calvin's face on numerous occasions.
- The Wyrmspawn is this in The Dark Lords Ascendant. It's incredibly powerful, capable of decimating an entire city with the mere shockwaves caused by its breath attacks. However, killing is the only thing it knows: if its senses are blocked off to the point where it can't detect anyone, it thinks everyone around it is dead and settles back down to wait.
- Heracles from Greek Mythology was stereotypically portrayed this way in Attic comedy (for example in Aristophanes' The Birds). In the "canonical" version of the myths, despite being prone to fits of irrational rage, he is not dumb, and occasionally pretty sharp — one of his most famous stories is the Twelve Labors, in which he is forced to find clever solutions to twelve seemingly impossible tasks.
- The titan Atlas. After getting Hercules to take over holding up the sky (heavens) for him while Atlas did him a favor, Atlas decides not to take it back as he likes his freedom. Hercules admits defeat then asks for Atlas to take the sky back long enough for Hercules to put a pad on his shoulder. Atlas agrees, and Hercules walks away. And this was the guy the other Titans picked to lead them against the Olympians after Cronus fell out of favor with the rest of them. No wonder they lost. Averted in an alternate version of the myth, in which Hercules and Atlas simply came to a mutually beneficial arrangement in which Atlas did the favor and Hercules built the Pillars of Hercules to carry Atlas's load forever. This version was less common as Atlas was an unpopular character and the ancient Greeks enjoyed making him out to be both a villain and a moron.
- In The Bible's Book of Judges can be found the story of Samson, a man with the strength to kill a hundred men with a donkey's jawbone yet lacking in pattern recognition skills to the point that he doesn't realize his girlfriend is actively betraying him to his enemies. For those unfamiliar with the story, the source of his strength was his long, uncut hair. When she asked about the source, he twice lied to her (first saying he needed to be bound with ribbon, then with rope) and was immediately afterwards attacked by men attempting to restrain him using the method he had confided in her. He finally confessed the true source of his strength when she confronted him, accusing him of not trusting her.
- Dice Funk: As the party's fighter, this is Rinaldo's role, although his frequently poor dice rolls make it easy to forget.
- Strong Mad from Homestar Runner. His idea of reading is looking at a waffle with "BUG" written on it in syrup. "THIS BOOK IS TOO LONG!"
- In The Fear Hole episode "All Hallows Adam," the character antagonizer is a parody on Nemesis with the brain and personality of a small child. And he is adorable. Too bad about what happens to him though...
- James Hetfield is depicted this way in Napster Bad—as a gorilla-like Neanderthal who talks in Hulk Speak. In "Metallica Millionaire", he's shown as being too stupid to answer a game show question about what band he plays in, even though every of the available answers is "Metallica" and the host outright tells him to pick anything.
