!! This series provides examples of:
* AndroidsAndDetectives: Pretty much
* ArmCannon: It's not used until later in the run, though.
* {{Badass}}: K
* BroughtToYouByTheLetterS: K's belt has a giant "K" on the buckle.
* CainAndAbel: [[spoiler: K's creator's brother is the BigBad.]]
* ChestBlaster: K has a cannon hidden in his right breast.
* ChestInsignia: Belt variation - K wears a prominent "K" on his buckle.
* CoolCar: Joker, K's souped-up patrol car. (Built around a Nissan Fairlady Z - Datsun 240Z in the US.)
* CoolHat: K's flat cap.
* FantasticRacism: The Chief Inspector despises K because he is a robot and nearly resigns from his position at one point. He gets better later on though.
* FlyingCar: Joker, literally.
* JobTitle
* KaleidoscopeEyes: K normally has yellow eyes. They turn blue when he's sad, [[RedEyesTakeWarning red when he's pissed (or during battle)]], and silver in Blow-Up mode.
* [[AnimeFirst Live Action Show First]]: Ishinomori penned up a tie-in manga; it's quite different and a little darker, but he was satisfied with it (it helped that the TV show didn't have ExecutiveMeddling or RealLifeWritesThePlot situations come up that would force story changes).
* MidSeasonUpgrade: Blow-up mode
* MonsterOfTheWeek: The criminal robots hired out by BAD fill this role.
* MoreDakka: Blow-Up form.
* NewPowersAsThePlotDemands: Or as much as this trope can apply to robots... If the situation warrants it, K will swap out parts for more suitable ones. (In episode 8, for example, he swaps in some anti-electricity equipment to deal with Kaminari-man's Thunder Beam.)
* ObviouslyEvil: Their name is BAD. That means they're probably, well, bad.
* OneLetterName: K, our eponymous Robot Detective. (One song refers to him as "Kei", though.)
* PaperThinDisguise: Ganrikiman (from Episode 14) doesn't seem to get recognized as a robot when in disguise despite the fact that his head looks like a giant pair of binoculars and only covers his face with a scarf.
* PeopleInRubberSuits: Used to create K and the robots he fights.
** Averted when K's wearing normal clothes - the suit actor[[note]]a different one from the rubber suit actor[[/note]] is pretty obviously wearing only the mask.
* PluckyComicRelief: Jihei Jigoku, the "information salesman".
* ProfessionalKiller: One way BAD operates is to sell out one of their robots for assinations.
* RummageSaleReject: K intentionally dresses like this (yellow cap, red blazer, white pants) to avoid scaring people, as robots aren't commonplace in the setting. Averted when he wears a snappy trenchcoat over all that (and this is an image that tends to stick).
* SuperSenses: K is equipped with various electronic sensory devices that aid him in searching for clues or tracking perps. These include very sharp hearing, radar, telescopic vision, and a spectrograph in his eyes.
* ShoutOut: The series itself is a homage to Creator/IsaacAsimov's works, specifically the ''Literature/IRobot'' series of stories. In particular, the Chief Inspector is a direct {{Expy}} of Elijah Baley, with his relationship with K mirroring Baley's relationship with R. Daneel Olivaw.
* SomethingPerson: BAD's robots tend to have names ending in "-man".
* SpiritualSuccessor: ''Series/TokusouRoboJanperson'' has more than a few things in common with K.
* ThisIsADrill: K gets a Drill Arm in Blow-Up Mode
* ThemeNaming: The plot of episode 8 revolves around a trio of siblings named Ichiro, Jiro, and Saburo - "first son," "second son," and "third son," respectively.
* TransformationSequence: To get out of his disguise, he'd throw his coat and hat up in the air (they always folded together), and his Blow Up mode.
* TurnsRed: Literally, for Blow-Up mode.
* WallCrawl: Nanatsuman, the criminal robot in episode 5, could walk on ceilings with suction cups on his feet.
* WhatMeasureIsAMook: K has no problem killing the Mooks, even though they are part-human(cyborgs). He has a policy of [[FridgeLogic not killing humans]]...
** Of course this leads to WhatMeasureIsANonHuman. Since the Mooks aren't fully human (and of course are often trying to destroy the heroes) K can get away with killing them.
