LEGO A/S👁 Image
, known by their trade name The LEGO Group,^note the all-caps "LEGO" is a stylization, which you'll see throughout This Very Wiki is a major toy company founded by carpenter Ole Kirk Christiansen in Billund, Denmark in 1932 that's world-famous for its line of construction toys, consisting of numerous plastic bricks.

The company's name comes from the Danish phrase "leg godt", which translates into English as "play well". While not an influence on the name, the fact that "LEGO" can also mean "I build" in Latin has been embraced by the LEGO Group. The product is legally identified as LEGO bricks, not "LEGOs", and the fandom will be unfailingly quick to remind you of that fact.

Experts on children have called them the ideal toy — they're easy to use, are infinitely expandable and foster creativity. And by infinitely expandable, they mean infinitely expandable — even the earliest bricks made in 1949, when they first started their construction toy business, are 100% compatible with bricks manufactured today. There are also (nearly) infinite permutations on how you can combine them, with only 6 of the basic 2 by 4 bricks being able to be combined 915 million different ways!

Over the decades, in addition to selling basic boxes of bricks, LEGO has produced a vast array of "themes", collections of related playsets devoted to a general setting and concept (and occasionally, an overarching story), exploring a diverse range of time periods, places, jobs, characters, genres and even styles of building.

Prior to 1999, the LEGO Group avoided adapting licensed properties, reasoning that LEGO was its own very successful property. But in 1999 that changed, with the LEGO Star Wars line, which was insanely successful. The LEGO Group now has a myriad of licensed themes based on a wide variety of popular franchises. It's almost easier to list the ones they don't include: those owned by other toy companies (e.g., Halo^note Which is currently owned by Mattel's Mega Construx.), and those not age-appropriate (e.g., Game of Thrones).^note Though LEGO would loosen this restriction up in the late 2010s after introducing an 18+ range of sets aimed at adults, with several adult-oriented licenses (e.g., The Office (US), Seinfeld, and The Big Bang Theory.) receiving sets in the range. Though even so, it's unlikely that more R-rated works like Game of Thrones would receive themes anytime soon. Though even this has signs of loosening up as well, as LEGO would introduce a minifigure of the titular character from Echo (2024), a TV-MA show, as part of the LEGO Minifigures Marvel Studios line.

LEGO has also now expanded to other products and merchandise beyond their construction toys. LEGOLAND is an international chain of theme parks based on LEGO. And there are also numerous video games and animated cartoons based on LEGO, most notably The LEGO Movie, produced by Warner Bros. and released in 2014.

Tropes about LEGO:

• Accordion to Most Sailors: One of the LEGO Creator 31109 Pirate Ship👁 Image
  alternate models is the Pirates' Inn, which includes an accordion for one of the pirates to play.
• Actual Pacifist:
  • The creator of LEGO, Ole Kirk Christiansen, having lived through WWII, was one. It is for this reason that LEGO does not make military sets, and even the first gun pieces for pirates and the like in the 1990s were controversial within the company. This is also why LEGO bricks initially came in bright primary colors that didn't include grey or brown; Christiansen didn't want kids to make realistic military vehicles and gear out of them (not that it actually stopped them).
  • The company today is more of a Technical Pacifist that allows for Family-Friendly Firearms and stylized depictions of real weapons. Depictions of medieval/pre-modern or fully sci-fi futuristic warfare are apparently fine (consider the Castle, Pirates and Star Wars sets). It's just the modern and World Wars era that LEGO mostly refuses to cover. There have been a handful of exceptions through the years, though, including a series of collector's👁 Image
    models👁 Image
    featuring a Sopwith Camel and a Fokker Triplane, two World War I fighter planes, as well as a handful of Indiana Jones sets featuring the Arado Ar 96👁 Image
    ^note  Technically, the plane in the movie is portrayed by a Pilatus P-2, an unarmed Swiss trainer. But in-universe it is probably meant to be an Ar 96, which was also a trainer but had a secondary task as a light attack plane plus another World War I fighter in the Albatros D.III. Furthermore, the F-86 Sabre and Mark VIII heavy tank both have official designs depicted in Lego Indiana Jones 2, but these were never released into physical sets. The Wonder Woman (2017) sets also depict World War I-era fighter planes.
  • It should be noted that this policy only extends to the weapons themselves, and there is technically nothing stopping soldiers of these periods from being depicted, Those Wacky Nazis featured in the Indiana Jones theme (albeit with No Swastikas) being the stand-out example. Likewise, the "Green Army Men" from the Toy Story line are a hand and head swap away from becoming 50s American GIs, who likewise have counterparts in the Soviet soldiers who also hail from the Indiana Jones sets.
• Agony of the Feet: From the many jokes, you'd think LEGO was a brand of caltrops, and many LEGO fans (or the parents of fans) have suffered from stepping barefoot on a piece. LEGO themselves eventually became well aware of this, including Self-Deprecation gags in the Minifigures Goblin's bio, LEGO Dimensions, a line of novelty "building nightmares" horror posters, and The LEGO Movie 2: The Second Part.
• Amusement Park of Doom: Two in the DC line; a small funhouse featuring attractions for Joker, Harley Quinn, and the Riddler, and a much larger park with rides for Joker, Harley, Poison Ivy, and the Penguin. Both sets have several traps for Batman and Robin (and Beast Boy and Starfire) to face.
• Anti-Frustration Features:
  • Since it's very easy to lose the manuals for sets over time or impractical to keep a large number of them, LEGO has posted the instructions for thousands of the sets online to read free of charge. You can see them here.👁 Image
    
  • LEGO pieces can be difficult to take apart sometimes, especially with small tiles or plates in the middle of larger plates or stacked on each other. To this end, LEGO solved its own problem by manufacturing brick separator tools that grip onto pieces and provide leverage to wrench them off, and can even be built into a model if you really want. Later, LEGO did one better than just selling the tool themselves, first-party: they designed a slimmer, more attractive version with added functions—the other end of the brick separator is designed to wedge under tiles to remove them, though this will wear down the plastic on the separator, and the top side has a short Technic cross axle extension that can be used to grab 2x2 round plates out of an assembly from underneath, or to start punching an axle rod out of some cross holes you want to remove it from. LEGO began tossing one of these new separators into every large set to ensure that buyers would have one for free. A devoted collector will never have to look far for a brick separator again. This second brick separator piece is also nearly always released in LEGO's standard orange color, making it very easy to spot in almost any context to make sure the piece doesn't get lost in other bricks.^note Brick separators also come in teal, often in cases where sets use a lot of orange bricks to preserve visual contrast.
  • The (sadly long discontinued) LEGO Brick Vac, a hand-operated gadget that let you roll up LEGO pieces quickly into one bin to save you the trouble of picking them all up while saving your feet from a world of pain as a welcome bonus.
  • In lieu of the Brick Vac, LEGO has released official LEGO Slippers to help protect users' feet from the bricks.
  • If you break a brick or a certain part of a set or simply misplace part of it (very common with small parts like 1x1 studs) you can buy replacement pieces (over 11,000 to choose from) from the LEGO website. In general, the fact that LEGO sets largely consist of common parts, almost all of which are modular to begin with, makes it fairly easy to replace certain bricks with ones taken from other LEGO sets.
  • Bags containing the smallest pieces, discounting minifig pieces, always contain redundant spare copies of those tiny parts to prevent one rolling on the carpet or under a table and getting lost from holding up progress on the model. This practice has migrated to the Minifigures line, with their smallest parts getting a spare in the packaging.
  • Later sets started breaking model pieces into chunks packaged in separate bags to make processing the build and hunting for the necessary parts easier, with the instructions taking a "one bag at a time" approach.
  • Nowadays, the creators deliberately avoid putting hard-to-distinguish bricks in the same set to save you from frustrating "damn, I was supposed to use the non-painted tiny bricks 50 steps ago, time to disassemble the whole thing" moments. This explains oddities like redundant printed bricks used in spots where the print won't be visible anyway.^note It's also better for logistics, since it means one less type of brick in that set.
  • LEGO Technic axles come in many different lengths and are precisely sized for their functions in each model design, and don't have markers that can be counted like the studs on a brick. To address this, in sets with multiple lengths of axle that might be confused, the instructions pop in a 1:1 "actual size" graphic of the axles in those building steps so the builder can identify the axle they need at that point by holding the axles up to the graphics on the page to find the matching size.
  • Other pieces of LEGO gear are officially manufactured for display of minifigures or storage of parts, including bins with "brick sorter" meshes that let you pan-sift parts into layers by size and organize out the smaller parts automatically.
• Art Evolution:
  • While they always rely on the tried and true bricks, later sets have gotten more creative and sophisticated and sometimes use more specialized bricks to allow details and forms more sleek than what regular bricks allow. A comparison👁 Image
    ◊ of the numerous Slave 1 Lego sets really highlight the difference between the older, more basic and blocky looking LEGO sets and the more series accurate, detail heavy ones on the market today.
  • The minifigures have also evolved considerably over the years. The first minifigures had the typical head, but no faces and static bodies consisting of torsos and legs with low detail and no separate jointed limbs. For much of the 70s, 80s and the early-to-mid 90s, minifigures found their standardized body shape but often looked very basic and tend to feature only one expression (a smiley face). Starting in the late 90s though, minifigures would gradually gain more detailed torsos, as well as much more varied and unique expressions, better distinguishing them and giving them more personality. Beginning in the 2000s, Lego licensed sets would shift away from using yellow as the default skin color in favor of using more realistic skin colors (sets that are original Lego IP still use the classic yellow though). LEGO has also begun to break away from the typical minifigure mold for some in favor of making specialized and unique molds, particularly for larger characters and uniquely stylized characters whose designs can't translate well to the typical mold, though this saw a reversal from the latter half of the 2010s onward, where more minifigure designs adhered to the classic sculpts and licensed cartoon art styles were not replicated, instead pushing the licensed source material toward LEGO's standardized art style—compare the original Toy Story minifigures from 2010 to the Toy Story 4 minifigures from 2019. LEGO's molding and printing has also advanced to the point that arms and legs can be printed all over and legs can be molded together in different-colored halves to draw a clean line between the top and bottom for the purpose of representing skirts or shorts or boots more clearly.
• Ascended Meme: The Goblin minifigure👁 Image
  likes stealing bricks and hiding them under people's feet, referencing their reputation as foot pain incarnate.
• Awesome, but Impractical: Some sets include mechanisms that allow them to shoot studs. These are very cool, but also very problematic. For one, they shoot the studs far, and those little things have an annoying tendency to get lost. For another, they can be a pain to reload, and if you're not careful you might shoot yourself in the face.
• Bat People: The Bat Monsters from the Monster Fighters theme and the similar-looking Vampire Bat from LEGO Minifigures Series 8, using a different arm pieces that curves upward horizontally with a webbed wing on the underside.
• Bedsheet Ghost: The original ghost minifigure👁 Image
  introduced in the 1990's are essentially a white LEGO minifigure wearing a sheet over their body that leaves their eyes and arms exposed. The sheet itself was designed to glow in the dark.
• Built with LEGO: Naturally, and especially at a convention by fans. Rule of thumb; if it exists, you can make it out of LEGO.
• Call-Back: The brand is full of inside references and homages to older LEGO themes and characters as treats for longtime fans to discover.
• Captain Colorbeard: The iconic minifigure who plays the part of the captain for the old Pirates sets is officially named Captain Redbeard. He's got all the traditional pirate traits: a Sea Dog Beard, a bicorn hat, an Eyepatch of Power, a Hook Hand, and a Seadog Pegleg.
• Company Cameo: Several LEGO sets feature LEGO merchandise being sold in them, such as the LEGO City set "LEGO Truck" (which actually has a box for the set itself inside) and the LEGO Monkie Kid set "The City of Lanterns".
• Cool Car: The Creator line has made a number of cars at a much larger scale than the typical minifig scale, both licensed (like the Ferrari F40) and unlicensed. The Technic line one-ups this with a number of vehicles with fully functional internal mechanics, such as the top tier Porsche 911 which has a 6 speed paddle shifter gearbox, steering rack, and a flat-6 engine. Large Technic sets are typically designed so that it's fairly straightforward to add a Power Functions motor to them, turning them into remote controlled cars. And then there's the full-scale, drivable LEGO Technic Bugatti Chiron👁 Image
  that The LEGO Group's own engineers built almost entirely out of LEGO Technic pieces (only a few parts, such as the wheels and tires, were not made of LEGO parts). It's even propelled by a powertrain made up of 2,304 electric motors, allowing for the car to reach blistering speeds of 12.4 miles per hour.
• Crippling Overspecialization: While a big selling point of LEGO is its sophisticated engineering and compatibility across parts of many different types, there have been a few parts over the years with extremely limited application, with the Galidor line being the most standout example: It had characters more like action figures, but could still be mixed and matched together, but the parts only really meshed well with others in the Galidor line, leaving them very difficult to use with regular LEGO parts and sets. The fandom even has its own acronym for seemingly ultra-specific parts used in creative ways other than what they're intended to be: NPU, meaning Nice Parts Usage.
• Dangerous Forbidden Technique: Some ways of combining bricks are banned in official models (for example, placing a plate edge-on between two rows of studs, or mating the protruding stud from a headlamp brick with the hole in a Technic brick). The danger is that the bricks may be placed under stress and possibly damaged.
• Dem Bones: Skeletal minifigures👁 Image
  started to become fairly common from the mid-90s on. They have the same proportions as the regular minifigures and use the same headpiece (albeit designed to look like a skull), but unlike regular figures, they have a hollow ribcage, both legs are connected separately, and the arms are attached via a loose ball-and-socket joint (later replaced by a bar joint with clip-on arms that move like a regular minifigure's). Skeleton minifigures have become a LEGO icon in their own right as they've been remains in adventure themes and animate creatures in horror or fantasy themes, and the classic original LEGO skull print is still in frequent use, unlike other contemporary prints which are officially considered outdated or retro.
• Design-It-Yourself Equipment: The only limits to what you can make with LEGO are the number of bricks you own and your imagination. And for those who can't afford the sets, there's always the free LEGO Digital Designer program, then later Bricklink Studio^note following the LEGO Group's acquisition of Bricklink in 2019 and the discontinuation of LDD in 2022, and the open-source LeoCAD👁 Image
  , all of which allow you to build virtually any LEGO set you desire.
• Disney Owns This Trope: Zigzagged. The patent for the bricks expired long ago, and LEGO has so far been unsuccessful in their efforts to trademark their iconic 2x4 brick, hence why you'll find very similar brands of construction sets like Mega Bloks on the market. Hasn't stopped LEGO from trying to take legal action against them time and time again, though. However, LEGO does have trademarks on more specific kinds of their LEGO parts, such as their famous minifigures.
• Dressed to Cook: Sets from the 1980s and 1990s with a kitchen or snack bar, the figure behind the counter usually wears chef's whites and a hat.
• Ear Fins: The Swamp Creature from the Monster Fighters line and the Swamp Monster from the Scooby-Doo line use the same fin-eared headgear piece👁 Image
  .
• Early-Installment Weirdness:
  • The earliest LEGO products weren't even construction bricks but wooden toys. They didn't even start making plastic toys until 1947, and it took another couple years before they even made their first precursor to a Lego brick, the Automatic Binding Brick.
  • And even then, the brick in its iconic form wasn't finalized until 1958, and the bricks before that had limited interlocking and a less modular design.
  • It took until 1956 for most of the "classic" colours (red, yellow, blue, white, light gray, transparent) to be standardised. Before then, bricks came in a variety of colours (at least 20 are known), including green, which was later limited to baseplates and foliage for a few decades. The last "classic" colour, black, came along in 1960.
  • Certain colors have been phased out or changed. Brown used to be less red-toned until getting permanently switched to the current reddish brown shade, and the two grey tones were changed from a more yellowish grey to a bluer tone as well. Other colors, like sand red and sand purple, had limited use before being removed from the color palette. Chrome-metallized pieces also became discontinued and replaced with pearl metallic colors.
  • Bricks before 1963 were made of cellulose acetate, which was prone to warping and discoloration. The material was changed to ABS (acrylonitrile butadiene styrene) polymer in 1963.
  • LEGO products were initially manufactured and distributed in the U.S. and Canada through Samsonite, a company best known for luggage. The licensing deal was broken off in 1972 with LEGO itself taking over North American production, though Samsonite remained the Canadian distributor for LEGO until 1986.
  • Minifigs weren't introduced until 1975, and the earliest ones prior to 1978 had no faces, arms or movable legs.
• Easter Egg: Some sets include subtle details in unexpected places which can be seen as Easter eggs. For example, the Saturn V set from LEGO Ideas has a piece count of 1,969, referencing the year of the Apollo 11 mission to the Moon.
• Excuse Plot: For most original themes, any story surrounding them is minimal so that the child playing with the toys can imagine one. That is, if there's any story at all.
• Fun Size: LEGO has made novelty lines of small exaggerated vehicles in the Super Heroes and Star Wars lines, and advent calendars demonstrate just how small a LEGO model can get.
• Family-Friendly Firearms: See under Actual Pacifist. This was the company's stance for a long time, and to some extent it still is today. For example, you still won't see any LEGO models representing realistic military vehicles (with the exception of two collector's👁 Image
  models👁 Image
  featuring a Sopwith Camel and a Fokker Triplane). They aren't quite as strict about it as they used to be, though; since they were first introduced with the Pirate theme in the 1990s, stylized minifig-scale guns have appeared in the Adventurers, Batman, Indiana Jones and Wonder Woman themes, but they're all noticeably "classic" or outdated to keep them from being too uncomfortably modern.
• Fun with Acronyms: The LEGO community has developed a large amount of acronym-based terminology—AFOL (Adult Fan of LEGO), TFOL (Teen Fan of LEGO), MOC (My Own Creation), SNOT (Studs Not on Top), and more. Others include BURP (Big Ugly Rock Piece), NPU (Nice Parts Usage), and POOP (Piece Out of Other Pieces) are some examples.
• Get Back in the Closet: The "Everyone is Awesome👁 Image
  " set is based on the Progress Pride Flag and was released in June 2021. However, queer LEGO fans have noticed that the set is online-exclusive and rated 18+ despite its relative simplicity. LEGO responded to the criticisms by saying that the mature rating is due to the set being a display piece and not a toy, though cynical folks believe it was to keep Moral Guardians at bay, likely the same reason it's not available in stores.
• Getting Crap Past the Radar: The company has an internal policy, made official in 2010 after many years of being the de facto rule, of avoid[ing] realistic weapons and military equipment that children may recognize from hot spots around the world and to refrain from showing violent or frightening situations when communicating about LEGO products. At the same time, the purpose is for the LEGO brand not to be associated with issues that glorify conflicts and unethical or harmful behavior.👁 Image
  In short, sets depicting modern-day military weapons are not permitted. ^note Older "historical" military weapons tend to get a little more leeway— the Indiana Jones and Wonder Woman sets both include period-appropriate military vehicles. However, a few kits manage to sneak through the cracks.
  • This set👁 Image
    is clearly meant to be a Lockheed F-35 Lightning II strike fighter, but since it's labelled simply as a "Blue Power Jet" instead, it technically doesn't violate the company's non-violence policy.
  • The V-22 Osprey👁 Image
    set was an interesting case. Although in real life the V-22 is strictly a military vehicle, the LEGO version is depicted in civilian markings and makes no mention of its use as a vehicle of war. However, a German protest group pointed out that, as a licensed model, it would still be providing money to weapons manufacturers regardless, and LEGO withdrew the set in response. It got past the company's "radar" just fine, but it couldn't get past the protests.^note  Those lucky few who managed to snag a copy of the V-22 realized the set was poorly designed, and that critical pieces would break from use of the toy functions due to the errors. Some in the Lego fandom suspect Lego accepted the German protestors' demands as a cover-up over the poor quality control in the set, which would have been recalled anyways due to its flaws.
  • This set👁 Image
    can be built into a jet fighter resembling a Sukhoi Su-15 as well as a twin-engine prop plane based on a Douglas A-26 Invader. Once again, neither is explicitly named, giving the company a degree of plausible deniability. The same is true of this set👁 Image
    , which can be built into a Northrop F-5 Tiger or a De Havilland Mosquito.
  • One of the Toy Story sets👁 Image
    depicts the plastic soldier characters along with an Army Jeep. Ordinarily this would be a clear violation of the "no modern weapons" policy, but since it's based on Toy Story, as opposed to representing a real-world vehicle, it gets a pass.
  • There is an entire theme👁 Image
    based around the Coast Guard, which is, legally speaking, a branch of the military. However, the Coast Guard's primary function is rescue and law enforcement, making it acceptable by the company's standards. That said, at least one of these sets contains a model that wouldn't be allowed in any other context— a rescue helicopter that is clearly meant to be a Sikorsky HH-53.
  • The James Bond Aston Martin set👁 Image
    includes a Bond minifig that is pictured holding a wrench. However, one of the pieces is a small black section of pipe that goes under the car but is blatantly shaped like a pistol (including a trigger). It fits perfectly in his hand and you're given a spare...
• Green Gators: LEGO crocodiles and alligators are almost always green or dark green, as depicted in Fabuland, LEGO Pirates, LEGO Adventurers, LEGO Indiana Jones, LEGO Agents, LEGO City, Legends of Chima, and The LEGO Movie. There are rare exceptions, such as Legends of Chima having the brown-scaled Crug in the otherwise-green Crocodile Tribe, or Hidden Side having a tan-colored crocodile in its Deep South-inspired setting, but green is the most common color. In the Batman line, the figures for Killer Croc, a crocodile-like man, are all colored green, although the later versions are more of a muted green compared to the original design's saturated dark green.
• Humongous Mecha: Exo-Force was a line of anime-inspired mechas with very much anime-inspired pilots. The mechas introduced heavy-duty clicky two degree of freedom joints, allowing them to be posed like an action figure. Mechs have been a staple in sets since Exo-Force, particularly in its next Japanese-inspired franchise, Ninjago, but mechs have never since been the baseline concept of a theme.
• Impossible Hourglass Figure: Hourglass waist contouring featured in many female minifigure designs, merely printed on the standard torso shape, though the emphasis on feminine curvature has reduced in later female minifigures, who tend to have more neutrally-designed torsos unless the costume is of a style that would be form-fitting.
• Insistent Terminology: Officially, LEGO is stylized "LEGO", in all caps. Additionally, the company specifies that "LEGO" is a modifier, and when not referring to the company, is not a noun. A brick or minifigure or a set is not "a LEGO". They're LEGO bricks, LEGO minifigures, and LEGO sets.
• The Lethal Connotation of Guns and Others: The franchise as a whole for a long time had a strict no-guns policy, which was only repealed in the 1990s with the release of the Pirate and Western themes.
• Made of Indestructium: LEGO bricks are notoriously resilient and will stand up to many years of use before they start showing any sign of wear, with many decades-old bricks holding up perfectly next to modern ones. Sometimes, LEGO dyes weakened their bricks' integrity for certain colors, allowing them to snap, but such issues have been addressed.
  • One notorious aversion were brown LEGO pieces with their brittleness. They could break easily when different colored pieces would not break under the same pressure. Thankfully, this has been remedied in recent years as brown pieces have been more resilient to damage.
• Meaningful Name: Two-fold; as explained above the name LEGO is derived from the Danish "leg godt", meaning "play well", but it also happens to be Latin for "I build", which is exactly what LEGO bricks are meant for.
• Mini-Me:
  • The nanofigures are tiny static statues of bald basic minifigures on a 1x1 stud base. They debuted to be minifigure-shaped award trophies for actual minifigures, and then became used to depict tiny figures in microscale builds, as well as the occasional tiny creature in minifigure scale.
  • The Super Hero Airport Battle👁 Image
    set, based off the scene from Captain America: Civil War, includes both Ant-Man as a nanofigure and a larger brick-built Giant-Man. A standard-sized minifigure Ant-Man can be found in other sets.
  • Inverted with the Up-Scaled LEGO Minifigure👁 Image
    , which is nearly six times larger than the standard, identically-dressed minifigure it comes with. Opening the hat reveals that the normal minifigure can use it as a giant mech.
• Monster Clown: In the DC line, Joker counts, but so does the clown-face archway on Jokerland. LEGO's first use of clowns in a horror context besides the Joker was in a set in the Hidden Side theme where the clowns end up possessed by ghosts.
• Mukokuseki: LEGO minifigures have yellow skin in order to be racially unidentifiable, though non-white characters like Native Americans and Japanese people still appeared as visibly different through costume and some face design changes. Licensed themes switched into using human skintones after an uneven debut with Lando Calrissian being singled out with realistic brown skin among yellow minfigures, which carried unwanted implications that LEGO yellow reflected white skintones. With LEGO's minifigure art design standardizing and its efforts to depict diversity increasing, the modern formula features standard minifigure yellow for most unlicensed minifigures, with face designs that don't caricature specific groups, but the yellow minifigures still have cultural/ethnic/phenotypic traits visible through things like costumes and hairstyles that demonstrate diversity.
• Never Smile at a Crocodile: Crocodiles were introduced in the mid-90s with the Islanders, and for those sets, replaced the sharks as the go-to animal hazard for the pirates to fall prey to.
• Nerd Hoard: Their ubiquity and pulling from countless classic Geek Reference Pool sources ensures that LEGO sets are common in most nerdy collections, both in fiction and reality.
• No Backwards Compatibility in the Future:
  • Averted. Save for specialized parts (i.e. the Technic or Galidor line) Lego bricks are designed to be modular and universally adaptable. A LEGO brick from 1958 will absolutely work with a LEGO brick from a set off the shelf today.^note Even then, Galidor parts ARE compatible with Lego bricks with the Galidor joint system becoming standard in later themes like Exo-Force and Ninjago. In addition, the feet of all Galidor figures do align with regular Lego studs although they lack clutch power to connect permanently.
  • Sadly, this doesn't apply to the LEGO bricks made from 1949 to 1957, which have limited locking ability and lack of versatility compared to the bricks from 1958 and on.
• The Noseless: Minifigures by and large don't have any noses on their faces, with noses on modern minifigures only rarely being included for more animalistic or monstrous figures, or licensed characters for whom a nose is essential, like Disney's Pinocchio, who has a unique head mold that's close to a normal minifigure head, just with a small pointed nose. Even the minifigure Fred Flintstone and Barney Rubble's cartoony noses are only alluded to by the silhouettes of their beards.
• Our Dragons Are Different: LEGO have produced a number of dragons over the years; single 'big fig' figures in the 1980s and 1990s in the same vein as LEGO horses, more advanced ones with additional articulation in the 2000s, and block-based dragons with large articulation in the 2010s Elves and Ninjago line. Almost all are quadrupedal with two additional wing limbs. The Elves line feature friendly magical dragons varying in size from a small car to a building, while previous sets - typically the Castle line - feature traditional knights and dragon slaying.
• Running Gag:
  • LEGO sets are known for including coffee mugs very frequently even in more fantastical or serious settings.
  • Similarly, the frog and hot dog pieces are infamous for frequently popping up for unconventional and unusual purposes in a wide variety of sets.
  • Across multiple spooky themes, and across a large gap of years, there was a running gag about depictions of Frankenstein's Monster having their foreheads closed up with different gag methods in lieu of stitches or staples. The original Monster from the Studios theme used a zipper. The CMF Series 4 Monster released nine years later has Band-Aids closing his forehead. Picking up from that, the Crazy Scientist's Monster from the Monster Fighters theme released the following year was based largely on the Series 4 figure but featured safety pins holding his forehead together!
• Serial Escalation: LEGO bricks have been mathematically proven to be the most modular toy ever made, and a major factor in why they're so popular and considered a legitimate creative tool. With only six off the shelf 2x4 bricks, there are a whopping 915,103,765 different combinations you can make out of those alone. Adding more bricks beyond that escalates the possible brick combinations into the billions and billions territory.
• She's a Man in Japan:
  • In Res-Q, the sunglasses-wearing pilot is a woman named Ariel in the American LEGO Mania Magazine or a man named Rick Rotor in the UK Bricks 'n Pieces Magazine.
  • In Extreme Team, the red daredevil is a woman named Alexis in the American LEGO Mania Magazine or a man named Daredevil Tom in the European LEGO Adventures! Magazine.
• Sinister Stingrays:
  • The Atlantis line includes villainous Manta Warriors.
  • Alpha Team had a "Mutant Ray" that was controlled by the villain Evil Ogel.
  • Mantax from BIONICLE, one of the six Barraki warlords, resembles a humanoid manta ray as a result of being mutated by the corrupting waters of The Pit. He is noted for his secretive nature and great distrust for the other Barraki (due to his knowledge that one of them betrayed the rest). Like real rays, he also has a tendency to hide in the seabed to ambush his enemies and has venomous spines (albeit on his head rather than his tail).
• Stealth Pun: Some of the brand's tongue-in-cheek humor counts as this. In the Brick Bank set, for example, the criminals smuggle stolen money out of the building via a hidden door in one of the washing machines (in the neighboring shop), which leads to an empty air vent. In other words, they're money launderers.
• Super-Deformed: The aesthetic of the Super Heroes Mighty Micros minifigures, using short legs and having simple yet exaggerated cartoon designs.
• Thematic Sequel Logo Change: Two toy ranges have used altered versions of the original Classic LEGO Space logo (a spaceship breaking out of its orbit around a cratered planet):
  • The 2022 LEGO City Space range use a version where the planet is Earthlike and the spaceship hasn't travelled so far, implying that this is earlier in the history of space exploration.
  • The Ice Planet 2002 sets carry a version where the planet has a prominent icecap and the spaceship is in a static orbit.
• Theme Naming: All of the Modular Buildings' names are exactly two words.
• Threatening Shark:
  • Sharks were introduced with the Pirate sets in 1989 and have been a mainstay animal piece ever since. Larger versions of the LEGO shark capable of swallowing minifigures (who aren't wearing bulky pieces or tall/wide hats) have also featured in several sets.
  • The villainous faction for the Aquazone sets were called the Aquasharks for a reason: all their submarines were built to resemble sharks. Their sets also usually included a shark for good measure.
• Trope Codifier: There were interlocking brick toys for decades before LEGO (the pre-1958 LEGO bricks were almost identical to Kiddicraft's Self-Locking Building Bricks) but LEGO caught the world's imagination in a way that its predecessors didn't.
• Undead Servant: The "Zombie Butler" from the Monster Fighters theme is the butler to Lord Vampyre. Unfortunately, he's clumsy and not very good at his job.
• Under Crank: LEGO commercials use this technique—whenever the set is being thrown together in the commercial, it's actually the model being taken apart in reverse so it looks smoother and faster when played forward at faster speed.
• Units Not to Scale: Mandatory, as LEGO Minifigures do not have the proportions of a regular adult human (they're closer in proportion to a 2 year old toddler). As a result any set built to properly accommodate the correct number of minifigures (i.e. a car that seats four) will end up being considerably taller than the height of the minifigure would suggest, while a vehicle built not to call attention to how short minifigures actually are will inevitably have to cram them in and likely won't fit the correct amount. And that's not even touching on the huge capitol ship playsets that come with minifigures; several of the Star Wars LEGO capitol ships would be hundreds, if not thousands of real world feet long at minifigure scale^{Scale example} At minifigure width scale, ~1:30, the Executor class Super Star Destroyer from Return of the Jedi would be 2,077ft long, and at minifigure height scale, ~1:45, it would be 1,385ft long . Because of this almost no sets are "properly scaled", with the majority of those that are being more out of coincidence (and part of the Ultimate Collector's Series) than deliberate design.^Specifically The only Ultimate Collector Series sets that fall within the 1:30-to-1:45 spectrum to qualify as "minifigure scale" are 75309 Republic Gunship at 1:30 scale, 10179 and 75192 Millennium Falcon at 1:40 scale, and 75313 AT-AT at 1:36 scale. The rest are mostly too small, such as 75060 Slave I at 1:50 scale..
• Unreliable Canon: Trying to decipher the canon (outside of its more story-oriented themes such as BIONICLE) can be a real mess, though it hasn't stopped many from trying. Perhaps the greatest unreliability is the LEGO timeline and universe.
  • Some sources state that each theme takes place in its respective era. For example, LEGO Pirates takes place in the 1700s during the Golden Age of Piracy. LEGOLAND, the first LEGO Racers, and LEGO Time Cruisers LEGO Mania comics apply Time Travel as a Hand Wave for crossovers.
  • On the other hand, there are so many crossovers between LEGO themes (such as LEGO Island 2, LEGO Universe, Soccer Mania, and countless LEGO magazine comics) without the Time Travel Hand Wave that it would seem that most LEGO themes take place concurrently. For example, this means LEGO Pirates would take place in 1989, simultaneously with LEGO Space Police.
  • Other sources (such as LEGO Universe, LEGO: The Adventures of Clutch Powers, and one UFO/Fright Knights commercial) imply that all themes take place concurrently, but each on their own separate planet. For example, the 2007 LEGO Castle theme would take place in 2007 but on the castle-themed planet Ashlar.
  • The LEGO Time Cruisers comics from World Club Magazine which interprets the many LEGO themes as The Multiverse, but even within certain universes there are unexpected crossovers. For example, there's one universe which has UFO and Fright Knights interacting on Castle Planet (tying into the previously-mentioned commercial), and another universe which has Western, Extreme Team, Res-Q, and Adventurers all taking place simultaneously.
  • The LEGO Movie depicts all themes as taking place concurrently. They are all part of the same planet but were separated into separate theme-based zones under the rule of President Business, who dislikes crossovers. The setting of Classic LEGO Space, for example literally being a brick wall away from the settings of the LEGO Western and LEGO Castle themes. In reality, the entire LEGO world is the basement of "The Man Upstairs", with each zone represented by a different table. This may imply that LEGO's canon is all based on how each LEGO builder perceives it, and thus its inherent subjectivity explains why the canon is so unreliable.
  • When Everyone Is Related, things become even more unreliable. For instance, Evil Ogel is the great-great-great-great-great-grandson of Lord Vladek, implying that the two themes take place seven generations apart. The Evil Knight served under both Lord Vladek and Cedric the Bull, who has interacted with the casts of LEGO Island and Soccer Mania, both of which had a Crossover with Alpha Team in one of the LEGO Magazine comics... which would imply that Alpha Team and the second Knights' Kingdom themes take place around the same time, not seven generations apart. And let's not get started on Johnny Thunder's family tree...
• Updated Re-release: They frequently do this with their sets, most noticably with Star Wars, where iconic vehicles or scenes are remade after a couple of years with better builds and minifigures, rinse and repeat. The original Toa from Bionicle also got rereleased like this just near the end of the original series run.
• "X" Makes Anything Cool: The X-Pod sub-theme, released between 2004-2006.
• You Don't Look Like You: The clown archway in Jokerland only shares the green hair, white skin, and red lips with the character who owns it. The archway has a red nose, two tufts of green hair, and a bowler hat.
