A popular Japanese racing game series based on pullback toys created by Takara Corp. since 1978. The toys the games were based on were [[SuperDeformed chibi cars with smal ledge between front and back tires]] with a coin slot the back. With a coin inserted in the slot, the car will be able to do wheelies and stunts, hence being sold in America as "Penny Racers". The majority of them are caricatures of actual cars. Its popularity has led the company into making many spinoffs of the series. There were even [[ConvenienceStoreGiftShopping low-priced]] imitators of the toys -- {{Shoddy Knockoff Product}}s. The series did get imported overseas under the name of "Gadget Racers" and "Penny Racers" with help from other companies such as Conspiracy Entertainment, Midas Interactive Entertainment and Play It!.

The series is auto racing with an element of ''WackyRacing'' combined with loads of customizable bodies and parts. For instance; wings, water jet pack, speed boosters, [[FlyingCar gliding wing]], and [[TimeTravel time circuit]]. The customization in ''Choro Q'' is almost unlimited. You can put a racing engine in a garbage truck and drive in for a championship, or putting a huge 44 tires and wheels into a Le Mans vehicle to drive a hill climbling, or even a tank on a high-speed oval test course.

In 1997, ''Choro Q2'' introduced the WideOpenSandbox system that allows you to take a run around a town, unlocking shops and courses. ''Choro Q3'' (1998) added events and special hidden items into its town. And starting from ''Choro Q Wondeful'' (1999), the series introduced a full term of racing adventure system, complete with its own story and let you take a run between town, dungeons, or even time to advance the plot and unlock more courses. This concept is fully returned in the ''High Grade'' series from ''Choro Q HG 2'' to ''Choro Q HG 4'', in which HG 2 and HG 4 are imported to Europe and North America, in the name of ''Road Trip Adventure'' and ''Choro Q'', following in the order. And it's said that ''Road Trip Adventure'' is the best ''Choro Q'' game that exists outside Japan.

The original [[Franchise/TransformersGeneration1 Mini Autobots]] (Brawn, Cliffjumper, Bumblebee, Windcharger, Gears and Huffer) were largely based off of this line.

The spins off genre of the series are in the following list:
* ''[[ExcitedShowtitle ChoroQ!]]'' (Gamecube game and Mario Kart clone)
* ''Choro Q Jet'' (Racing jets and planes)
** ''Choro Q Jet: Jet Rainbow Wing'' (VideoGame/{{StarFox}} clone, with anime heroes instead of furries)
* ''Choro Q Marine: Q-Boat'' (boat and submarine race and battle)
* ''Combat Choro Q'' (tank battle, obviously says it on the tin)
** ''[[VideoGame/SeekAndDestroy2002 Seek and Destroy]]'' (sequel of ''Combat Choro Q'', called "Shin Combat Choro Q" in japanese, complete with story line and characters)
** ''Combat Choro Q: Advanced Daisakusen'' (Turned based strategy)
* ''Choro Q Park'' (racing game with a 'tag-team' system, where certain areas lets you switch cars)
* ''Choro Q Hyper Customable'' (Handheld game, with Monopoly-type system of racing instead.)
** ''Perfect Choro Q'' (uses the same system as above, but removes the ShoutOut element of Mini 44 toys.)
* ''Choro Q Works'' (another RPG with odd jobs and [[CelShading cell-shaded graphics]])
* ''Boku no Choro Q'' (a board game)

!!Tropes in these games
* ActionGirl: Ania, Kaybert, and Luluza in ''HG 4'', if you substitute "action" with "racing" in these kind of games. Ania is slightly better than other drivers.
* AmericanKirbyIsHardcore: ''[[VideoGame/SeekAndDestroy2002 Seek and Destroy]]'' is the best example for this series. See [[http://www.gamefaqs.com/ps2/583311-seek-and-destroy/images/box-25343 these]] [[http://www.gamefaqs.com/ps2/583311-seek-and-destroy/images/box-46631 two]] for references. Many other games' cartoony covers were changed when they were released oversea too.
* AwesomeButImpractical: The Devil & Angel parts are basically this. While they do upgrade your performance to new heights, you'll pretty much have a difficult time trying to control your car.
* CoversAlwaysLie: Some of the Choro Q covers published in US, mostly the Conspiracy games. While Road Trip is slightly true to the name, you would not think this game is about driving talking cute [[SuperDeformed super deformed]] cars, and the game being very Japanese.
** [[VideoGame/SeekAndDestroy2002 Seek and destroy]] has nothing to do with America. It has American tanks, but set in a fictional world [[AnimateInanimateObject with no human beings.]]
** Averted with with the Gadget Racers cover, being true to the game. The Atlus game and the Wii game kept their original Japanese covers.
* [[AlwaysCheckBehindTheChair Always Check Behind The Building]]: The basic of how to find Q-Coin in ''Choro Q HG-2''
* BigBoosHaunt: This setting appears at least once in each racing game from ''Choro 3'' onward, along with normal castles.
* BlandNameProduct: All the cars go by ChoroQ No.###, some with the option to rename them. Eventually subverted with Works, with cost of non-Japanese cars.
* {{Bragging Rights Reward}}/{{Infinity Plus One Sword}}: The Devil Parts in ''HG 2'', which can only be gotten after getting all 100 Stamps. Stamps are gotten by doing certain tasks... which include doing almost everything in the game, including beating [[FinalBoss Forest]] and getting all 100 Choro Q Coins. [[BrutalBonusLevel Tin Raceway]], on the other hand...
* BonusBoss: Kamikaze in ''HG 4'', almost unbeatable in "Trans-Trip L" circuit.
* BrutalBonusLevel: Tin Raceway in ''HG 2'', found in Cloud Hill after beating Forest. While Endurance Run seems like this because is not required to win the World Grand Prix, it gives a Stamp for beating it [[spoiler: and is actually the track where you race Forest.]]
* ContinuityNod: Forest, President and FinalBoss of ''HG 2'', appears in ''HG 3'' as an NPC, mentioning once having an incredibly boring job, which is most likely his presidency. His boredom of it was the cause of ''HG 2''.
* CoolOldGuy: Otto and Norahike
* DarkerAndEdgier: ''[[VideoGame/SeekAndDestroy2002 Seek and Destroy]]'', when compared to a kiddy show like ''Jet Rainbow Wings'', anyway.
* DeusExMachina: In ''HG 4'', [[spoiler:unable to catch up with the prince, Barat's spirit shows up and tell the player to follow his sixth sense to over boost himself and beat Otto to the finish line.]]
* DidYouJustPunchOutCthulhu: You in Combat series, especially ''Seek and Destroy'', where a punny take takes out a helicopter, a lot bigger tank, a battle ship fully armed with weapons, or various mutated monster tanks.
* FetchQuest: Being a WideOpenSandbox, there are some. A notable one requires you to travel around the world trade items with people, all to give one guy a rare magazine.
* FinalBoss: President Forest in ''HG 2''.
* FishingMinigame: Where you actually go into the water and catch the fish yourself.
* FlyingCar: A gliding wing part in ''HG 2'' comes in mind. Also, flying tank.
* GratuitousGerman: All of Kamikaze's in-game quotes are in German.
* GuideDangIt: For Choro Q 3, the are certain events/ background gimmicks that happen in town that happen. There are also minigames that require you to switch bodies for certain jobs (such as a police car for chases). But good luck completing the game 100%, [[NoExportForYou especially if you can't read Japanese!]]
** Try getting completing all events in Choro Q HG 4.
* InformedAbility: In Seek and Destroy's backstory, aparrently the Q-Stein (the bad guys) were wiping out the Proton Kingdom. [[ArtificialStupidity And then the game starts.]]
** The bosses are the ones that put up an actual fight, but still lack some kind of strategy.
* HauntedHouse: Unlike the ones used as racing tracks, Budbash haunted house in ''HG 4'' may make you wet yourself and forget about achieving 100% completion.
** The "short cut" in Nightglow raceway. But it is really just a maze made to slow you down.
* LimitedSpecialCollectorsUltimateEdition: ''Choro Q 64'' came with an assemblable toy car.
* LostForever: In ''HG 4'' for events and synthetic parts from Norahike [[spoiler: because he leaves the game after you beat Otto]].
** There is am embassy where you vote whether or not a track should be open to the public. If voted no, you cannot race in those certain tracks, meaning you can't collect all the prized bodies.
* MacGyvering: Synthetise in ''HG 4''
* MacroZone: ''Choro Q Wii'' is a standout example since it has Micro Machines feeling in it.
* MarketBasedTitle: Hoo boy, it is confusing:
** Choro Q HG in Japan, Gadget Racers in USA, Penny Racers in Europe.
** Choro Q [=HG2=] in Japan, Road Trip in USA, Road Trip Adventure in Europe.
** Choro Q [=HG3=] in Japan, Road Trip Adventure Avenue in USA, Gadget Racers in Europe.
** Choro Q [=HG4=] in Japan, Choro Q everywhere else.
** Choro Q Wii in Japan, Penny Racers Turbo-Q Raceway in the USA.
** Choro Q! ({{GameCube}}) in Japan, Road Trip: The Arcade Edition in USA, Gadget Racers in Europe.
** Choro Q Advance in Japan, Gadget Racers in USA, Penny Racers in Europe.
** Choro Q Advance 2 in Japan, Road Trip: Shifting Gears in USA, Gadget Racers in Europe.
** Choro Q 64 in Japan, Penny Racers in America and PAL Territories.
* NitroBoost: Boosters if there are available. [[spoiler: Otto]] also uses this in ''HG 4'''s climax battle
* NoExportForYou: Most games, since it's based on a Japanese toy franchise. But Choro Q ''HG 3'', which was supposed to be released in the US as "Road Trip Adventure Avenue" by Conspiracy entertainment, [[WhatCouldHaveBeen was canceled for reasons unknown]].
* OneManArmy: ''Combat'' series.
* OneWingedAngel: The BigBad in ''Seek And Destroy''
* RetiredBadass: Norahike, even though there is someone looks exactly like him in the Extreme Races
* TheRival: There's one who has a same body as you but in different color in ''Wonderful'', and Barat in ''HG 4''. The RX-8 in "Works".
* SentientVehicle
* SerialEscalation: ''WackyRacing'' tracks and parts from ''Choro Q 2'' onward.
* ShoutOut: The Team Getra's two co-drivers are named Michael and Ralf, who are brothers. You can guess where they got those names from.
** ''HG 2'' features [[IndianaJones an adventurer named Jones as an NPC.]]
** Also in HG 2, there's a guy named [[Literature/JamesAndTheGiantPeach James, and you give him a giant peach.]]
* SpiritAdvisor: [[spoiler: Barat]] in ''HG 4''
* StealthPun: One character in HG 4 hangs out in front of the school and brags about his intelligence. What kind of car is he? A Smart (as in the brand).
* SuperDeformed: All of them.
* SuperTitle64Advance: ''Choro Q 64'', one of the many {{Nintendo 64}} games that put 64 in their titles.
* ThatOneBoss: The Phantom from Penny Racers Party: Turbo-Q Speedway, (Choro Q Wii). Not only is he bigger than everyone else, but he is also surprisingly fast for his size. Not only that, but he's also guaranteed to catch up with you if you don't have the right parts. Not only that, but the track you face him on, The Lab-o-rinth is also pretty difficult due to the track's complicated layout. Making this boss surprisingly NintendoHard.
* TimeTravel: In ''Wonderful'', we have one in [[Film/BackToTheFuture DeLorean style]] with 300km/h required. There's also TimeTravel in ''HG 4'', but only for a short while.
* VehicularCombat / WeaponizedCar: [[ExcitedShowTitle ChoroQ!]], or Road Trip the Arcade edition in the US.
* VeryDefinitelyFinalDungeon: The World Grand Prix in ''HG 2''. The entire game builds up to it and it features one race from each town except My City and Cloud Hill. Completing it unlocks the race with President Forest himself.
** Cloud Hill somewhat qualifies, too. In contrast to the somewhat realistic setting the rest of the game was, Cloud Hill was incredibly bizarre. Not to mention [[FinalBoss President Forest]] and [[BrutalBonusLevel Tin Raceway]] being located here.
* WackyRacing
* WideOpenSandbox: Q2 onward. ''Wonderful'' improves it with multiple towns and people NPC in them.
* WidgetSeries: Well...
