[[caption-width-right:335:When you're a titanic, mutated beast of destruction, and a bandicoot can possess you via piggy back riding, you're a B.D.B.]]

A type of controlled [[BodyAndHost Host]] that is chosen for physical prowess and ability rather than anything else (usually also being simple minded enough that possession works without a hitch, although you don't need to be smart to have a strong will...)

Regarding possessors, a [[TheSymbiote Symbiote]] is an example where the host is usually the bigger and more physical of the two (or more) involved, as opposed to the parasite. While a DemonicPossession usually has the opposite, where the demon is the source of the host's strength and power, however, a B.D.B. possessed by such an entity becomes a LivingBodysuit.

Most B.D.B's are {{Giant Mook}}s or even bodyguards who are forced to take the blame for killing their charge after the possessor has relieved control (though this can end with the B.D.B also being discretely killed off to further suspicion and/or confusion.)

In some cases, it's safe to state that a B.D.B is a more powerful version of the standard MeatPuppet, though expected to be less common. Contrast TheDividual. Not to be confused with DumbMuscle, though DumbMuscle characters may ''end up'' as Big Dumb Bodies; or the BigDumbObject, whose only common trait is that they're big (and not even that they're dumb).

!!Examples:

[[foldercontrol]]

[[folder: Anime & Manga]]
* In ''Manga/OnePiece'', Kelly Funk has the Jacket-Jacket Fruit power, which lets him turn into a jacket and possess anyone who wears it. Kelly's preferred host is his brother Bobby Funk, who is naturally extremely strong and resilient, whereas Kelly is physically much weaker but is an experienced hand-to-hand fighter. Together, they become a very tough opponent, combining Kelly's swiftness and intelligence with Bobby's brute strength and toughness. This is [[DownplayedTrope downplayed]], however, in that Bobby is not dumb by any means, but [[ActualPacifist terrified of fighting and completely untrained in combat]].

[[folder:Comic Books]]
* The recurring ''Franchise/JusticeLeagueOfAmerica'' enemy General Eiling transferred his mind into the body of the indestructible Shaggy Man. In this case the host's stupidity became a problem, as Eiling's intelligence didn't survive being forced to use the Shaggy Man's tiny brain.
* Johan briefly had one in ''ComicBook/{{BPRD}}'' before it was killed by Captain Zombie's jaguar demon form. He's been trying with little success to clone a new one ever since.
* Warstar of Creator/MarvelComics's Shi'ar Imperial Guard is a form of this, consisting of a big guy ridden by a small one half-hidden on his back who does most of the actual thinking for the pair (and also has the ability to dish out electric shocks) -- to the point that at least once when he was taken out of action, his bigger partner stopped fighting, too. Oddly, the two seem to be ''robots'', suggesting that somebody may have designed them to embody this trope on purpose.
* ''Comicbook/{{Supergirl}}'':
** Subverted with enemy Wordkiller-1 -an alien, body-surfing symbiote-. In ''ComicBook/RedDaughterOfKrypton'', he transferred his soul into the body of [[spoiler:Supergirl]] because she was crazy powerful and inmensely strong, and he thought she was only a stupid girl. By the time he realized she wasn't dumb at all and [[spoiler:she had outsmarted him to force him out of her body and kill him, it was too late.]]
** In ''[[Comicbook/{{Supergirl 1972}} Supergirl Vol 2]] #8'', Medusa’s ghost wants to take over the titular heroine's body specifically because of her superhuman powers and not because of her brains.

[[folder: Film]]
* Master Blaster in ''Film/MadMax Beyond Thunderdrome'' was a genius midget on a dumb brute's back.
** "He has the mind of ''child!''"
[[/folder]]

[[folder:Literature]]
* In ''Literature/WarOfTheSpiderQueen'', Gromph Baenre, the Dark Elf Archmage of Menzoberranzan, once took control of a troll B.D.B to detonate one of several magical traps protecting a Traitor Noble House.
* In ''Literature/{{Animorphs}},'' [[PuppeteerParasite Yeerks]] can control a species no matter how smart they are, but their shock troops, the Hork-Bajir, fit the bill--they're [[https://www.google.com/search?q=Hork-Bajir&rlz=1CAACAP_enUS712US714&source=lnms&tbm=isch&sa=X&ved=0ahUKEwigkuO6lOLTAhVB64MKHXKMDTIQ_AUICigB&biw=1366&bih=591#imgrc=hQHqWHayG4QDbM: seven-foot-tall dinosaurians covered with blades]], but are [[GoodIsDumb simple-minded and peaceful]] in their natural state. (Those blades are actually for scrapping off edible tree bark.)
** The Gedds were the only hosts the Yeerks had on their home planet. Its ambiguous how sapient they are, but they're basically slow monkeys that all walk with a limp--once the Yeerks had other bodies to possess, Gedds became menial workers.
** The series reveal that [[HumansAreSpecial humans are the ultimate version of this trope]] as far as the Yeerks are concerned--not as good fighters as the Hork-Bajir, to be sure, but we're stronger than Gedds or Taxxons, breed quickly, are dexterous enough to be useful, and are technologically weak enough to be conquerable. Also, apparently we're the only sapient species that numbers in the ''billions.''
* In ''Literature/ASongOfIceAndFire'', Bran uses Hodor as a BigDumbBody.

[[folder:Live-Action TV]]
* In ''Series/StargateSG1'', the [[PuppeteerParasite Goa'uld]] prefer human hosts, by which they can pose as gods, but if they want something more durable they'll inhabit an Unas, a large humanoid that is short on brains but so tough it's nigh-bulletproof.
[[/folder]]

[[folder:Tabletop Games]]
* ''TabletopGame/DungeonsAndDragons'' (3.5) had an arcane/psionic prestige class called Mind Bender, which allowed characters to eventually gain mind controlled thralls (usually B.D.Bs to balance out the weaknesses of said spellcaster).
* Vilitch the Curseling, from ''TabletopGame/{{Warhammer}}'' has been magically attached to and overtaken the will of his hulking warrior twin Thomin, who acts as this for him.

[[folder: Video Games]]
* The premise of both ''VideoGame/CrashOfTheTitans'' and its sequel ''VideoGame/CrashMindOverMutant''.
* Used by Abe in the ''VideoGame/{{Oddworld}}'' series through the power of Possession.
* ''VideoGame/{{Messiah}}'', revolving around possessing people, naturally features these.
* The somewhat obscure robotic third-person shooter ''VideoGame/MetalArmsGlitchInTheSystem'' has MightyGlacier GiantMook "Titan" enemies who are common targets for Glitch's Control Tether -- they're considerably more sturdy than Glitch or most of the enemies faced in the game, and great for plowing through enemy squads, at least while they're free of SubsystemDamage.
* The alchemist in ''VideoGame/{{Dota 2}}'' has one of these which he rides on.
* As of its ''Cataclysm'' expansion, the first example of this trope new players will encounter in ''VideoGame/WorldOfWarcraft'' will usually be Helix Gearbreaker, a boss in the Deadmines. Helix is a goblin who fights atop a Lumbering Oaf. Once you kill the Oaf as part of the fight, he'll jump off and start riding on top of the players until defeated.
* The MiniBoss of [[DownInTheDumps Morph Moth's stage]] in ''VideoGame/MegaManX2'' is a small pink parasite-like bug that takes control of a large, durable, mostly-scrapped robot that jumps on X and fires junk. X will need to attack the big robot until it falls apart and releases the vulnerable small parasite, which will attempt to find another robot body if not killed in time.

[[folder: Western Animation]]
* ''WesternAnimation/EvilConCarne'' has the the eponymous Hector con Carne, reduced to a BrainInAJar, controlling the body of a bear simply by putting the jar with the brain on the bear's head. The bear is clearly ''technically'' free to do as it wishes, it's just so spineless it rarely if ever bothers to disobey.
