Robot Buddy



"Did you have fun with your Robot Buddy?"

- Homer Simpson asks Lisa after talking with Stephen Hawking, The Simpsons

The character is an artificially intelligent robot.

This kind of character is often good looking and has a million and one functions; if you need him to do a job, he has the right tool installed for it. Up to and including jet packs.

Typically, they are very loyal to their owners, requesting only proper maintenance like recharges and repairs. The trend in recent years is to make the Robot Buddy an obnoxious, cynical Deadpan Snarker, commenting on human foibles (or just those of the protagonist).

A bonus is that they can do a Heroic Sacrifice and still come back believably because Mr. Fixit can put him back together in the maintenance shop and upgrade him as a reward to be even better than before.

The logical opposite to A.I. Is a Crapshoot (except when it isn't). Compare Robot Girl, Do-Anything Robot, and Companion Cube. May also be a Funny Robot or Amusing Alien. If added to a story because of Executive Meddling or because the production team bought into the Sci Fi Ghetto, may also be an example of Kids and Cute Robots.

Anime and Manga

 * Doraemon in Doraemon.
 * In Eve no Jikan, part of the narrative is to ask if all robots should be forced to abide by this trope, for our own safety or otherwise, with some playing it straight while others subvert it.
 * Medabots, where everyone and their grandmother (literally) has one.
 * 2 foot tall beetle armed with 48-caliber revolver AND micro-missile? They're your friends.
 * Masha of Tokyo Mew Mew is the Robot Buddy crossed with the traditional Magical Girl's Talking Animal. He's a lot more simple-minded and cuter than either, and in the manga he also, under the right conditions, turns into the girls' penultimate weapon.
 * The Tachikomas in Ghost in the Shell: Stand Alone Complex are the sweetest, nicest little things you've ever seen, replete with childish voice and cute bubbly appearance. They are also armed with machine guns and grenade launchers (with an optional minigun attachment), and won't bat an eyelid (well, so to speak) at the concept of slaughtering entire platoons of bad guys. And yes, they do eventually perform a Heroic Sacrifice (twice).
 * They also have no concept of work, so apparently killing bad guys is their hobby.
 * The friendliness is subverted in one episode, showing that they're oblivious to anything being wrong with throwing a dog.
 * Gill/Giru from Dragon Ball GT.
 * Kurogane Communication has five for the main character: a general knowledge expert, a mechanic/chef, a ball-shaped gunner, a female sword expert and a domestic servant.
 * Steed, Tohma's robot buddy in Magical Record Lyrical Nanoha Force. With his contant floating, mono-eye, cylindrical body, and wire for arms, he kinda looks like a tiny Type I Gadget Drone. Is so far shown to have picture-taking and spying capabilities.
 * The robot television set from FLCL.
 * Akira Toriyama's Doctor Slump has Arale-chan.
 * There's a few Digimon that count, notably Andromon, Guardromon, and Shoutmon and Ballistamon.
 * The various Gundam titles have Haro. Its size and intelligence varies between continuities.
 * There's, of course, the original green Haro which is the largest in the franchise.
 * Gundam Seed has Athrun making various Haros for his fiancé. Her favorite is a pink one.
 * Mobile Suit Gundam 00 has Celestial Being using Haros to do technical work like battle repairs.
 * Lockon has his own orange Haro and even his Gundams are designed to interface with it. This one is arguably the most intelligent of the bunch as it frequently snarks at Lockon, calls Nena's Haro "nii-san"("Big Brother" in the dub) and even In The Movie, it gets a blue companion since Gundam Zabanya is too complicated for just one Haro.
 * Nena's purple Haro is as foulmouthed as Nena's brother and not only outright insults Lockon's Haro, it even knocks the latter away. Plus its extremely creepy when it starts talking Machine Monotone in Ribbons' voice.
 * In the second season, Saji is usually accompanied by a red Haro. It even assists him in piloting the O-Raiser and at one point foils a Gundamjack.
 * Telemachus' robot Nono in Ulysses 31.
 * Yu-Gi-Oh! Zexal; Yuma has Lilybot, a snarky Litterbot who becomes a Robot Maid, while Kite has Orbital-7, an exuberant (to the point of hyperactive) Do-Anything Robot. Both fit the Funny Robot Trope.
 * Yu-Gi-Oh: SEVENS has two characters with robot buddies:
 * Yuga has Kaizo, a Goha Corp drone that he rebuilt and upgraded into a Do Anything Robot. Kaizo's loyalty to Yuga is questionable, but his loyalty to Romin (whom he has a weird crush on) is absolute.
 * Nail has Sebastian, a massage chair with a sapient AI, who comes in very useful given how stressful Nail's job is. In the dub, Sebastian has a British accent, with an  uppity arrogant attitude, who prides himself on being an authority on the history of furniture making, being a chair himself. He has an ugly rivalry with Kaizo, and for good reason, his hard drive contains data that was stolen from Kaizo's.

Art

 * Julie Bell's "Robo Bird" shows a sorceress with her avian Robot Buddy. (Warning, NSFW.)

Comic Books

 * Booster Gold's Robot Buddy, Skeets.
 * Snivel and NSOB from the French series Sillage (known in the US as Wake).
 * This is more or less the entire point of DC's Metal Men. Complete with the Heroic Sacrifice in their original incarnation, they were all destroyed by the end of every single comic, and the last panel would be their scientist creator quietly picking up all the pieces for reassembly.
 * That's... kind of depressing.
 * Aaron Stack
 * Irona from Richie Rich is this and a Robot Maid.
 * Judge Dredd has Walter the Wobot.
 * Biotron and Microtron from The Micronauts, who each got destroyed and rebuilt at least once. Biotron even got to come back as a spaceship, once.
 * SLIC, the robot mechanic and best friend of Chassis McBain in Chassis.
 * His exact origin varies depending on which continuity it is, but the Ninja Turtles have one in the form of their ally Professor Zayton Honeycutt, aka the Fugitoid. A brilliant scientist whose physical body was destroyed only for his mind to be transferred to the body of his Robot Buddy, Honeycutt adapted remarkably well to his condition and became a potent ally of the Turtles, his robot body having a wide variety of useful functions which again, depend on the continuity.
 * Excalibur had a Robot Buddy named Widget, but the circumstances surrounding him were complicated. Initially believed to be invented by Crazy Gang member Tweedledope (who is an idiot savant, meaning his inventions cannot be duplicated)

Film

 * The Star Wars droid pair of C-3PO and R2-D2, with C-3PO's fluency 'in over 6 million forms of communication' and R2-D2's seemingly endless supply of gadgets for every conceivable task.
 * One of the signs that the Rocky franchise had gone completely off the rails was the weird and bewildering subplot in Rocky IV in which Paulie (Rocky's brother-in-law) gets a robot wife.
 * The robot arms in the movie version of Iron Man. They include one with a grip, one with a camera that the film sometimes switches to, and the most famous one, the fire extinguisher bot, who is really enthusiastic about his job.
 * The one with the gripper hand is remarkably clumsy. One wonders why Tony even bothers to keep using him at all, unless you pay attention during the magazine cover montage in the beginning of the film and see that he built that robot when he was in college.
 * Should be noted that the clumsy one, "Dummy" as Tony calls him, is also the fire extinguisher.
 * Bubo the clockwork owl from Clash of the Titans.
 * GERTY of Moon is more or less Hal's brother.
 * Bumblebee in Transformers seems to take this role on occasion. He gives the impression of actively trying to invoke the trope; Sam accuses him of faking muteness at one point to try and be endearing.
 * The third movie gives an almost darker version of this trope, with Soundwave and Laserbeak being "clients" to the human  However,
 * Huey, Dewey and Louie (no, not those three!) in Silent Running are three service robots on the Valley Forge, an American Airlines space freighter.
 * Robby the Robot in Forbidden Planet epitomizes this trope, and may have done it first in film.
 * BEN from Treasure Planet.
 * The trope is played with very casually in Funny People. One of the posters of his own movies George Simms has in his house is called My Best Friend is a Robot. No footage of the film-within-the-film is shown, nor is it ever mentioned in dialogue. We can glean from the poster that it also stars Owen Wilson, but there's no telling whether it's he or Simms who played the robot.
 * Charlie in Making Contact. He's next to useless, but cute and inoffensive and seems to represent Joey's connection to his dead father in a way since Charlie was given to Joey by his father as a Christmas present.

Literature

 * Perhaps the Trope Namer, the My Robot Buddy series, by Alfred Slote, features Danny One as the title character.
 * Tik-Tok from the Oz book Ozma of Oz is the earliest example of this trope.
 * Christopher Stasheff's Warlock series has Rod Gallowglass' companion Fess, a slightly-malfunctional robot retainer who often wears the body of a Mechanical Horse while on undercover missions.
 * The drones in books about The Culture by Iain Banks are loyal companions, but very deadly if they work for Special Circumstances. And even if they don't, they usually have attitude problems.
 * Norby in his titular series by Isaac and Janet Asimov. Telepathy, Hyperdrive, and Time Travel are just a few of his abilities. Incidentally, as it was made in 1985, he may be the first of the Deadpan Snarker bots.
 * Keith Laumer created the soul of a robot buddy and Warrior Poet in the Bolo. Imagine R2D2 as a massive tank, more loyal than Chewbacca, and with Honor Before Reason.

Live Action TV
"Gadget: Gadget, gadget! The Doctor: Does it have to keep saying that? Roman: I think it's funny. The Doctor: I hate funny robots. [He does mention later that dogs are different.]"
 * Data from Star Trek: The Next Generation plays this fairly straight most of the time, although there are a few times were it's subverted, and of course the episodes where Data's role and rights are examined.
 * Yoyo in Holmes And Yoyo
 * K-9 from Doctor Who, a robot dog.
 * Later, in School Reunion, Mickey starts describing how he helps out Rose and the Doctor, and comes to a sudden realization: I'm the tin dog!
 * In the old series, there was also Kamelion, who was a humanoid robot who, like his name suggests, could impersonate people. Unfortunately, this wasn't used to its full potential because the man who designed the prop (and thus, knew how it worked) died before he could pass the instructions on to anyone else. Thus, he was Put on a Bus every episode up until the one where he was killed off.
 * Gadget in "The Waters of Mars."

"I love my purple ball of fluff / I'll flip a switch and turn him off"
 * In Robin's previous life as a pseudo teen pop singer on How I Met Your Mother, one of her trademarks was a cute little robot sidekick.
 * What's hot, DJ Roomba?!
 * K-tai Investigator 7 is about the relationship between humans and cellphones that can walk, talk, and think. Really hard to miss the Robot Buddies in the series.
 * Robot from Lost in Space
 * Kevin from (I am not joking you) Saved by the Bell.
 * Hymie in Get Smart
 * On the show Lexx, the disembodied robot head 790 was once a programmed soldier working for the League of 20,000 Planets in the Light Zone, but gained new programming which it received in a process designed to give love slave training to the character of Zev, and ended up tagging along with the crew.
 * Tom Servo and Crow are the robot buddies of Joel Hodgson/Mike Nelson on Mystery Science Theater 3000, though they're not particularly useful apart from their capacity for wit and sarcasm (and with Crow, that's not always guaranteed).
 * Andy from Quark was a cowardly robot built by the titular character. He doesn't actually do anything, just complains all the time.
 * KITT from Knight Rider has the distinction of being a Robot Buddy main character. As such, he gets a lot more personality than your typical Robot Buddy, and gets to make more demands of his partner Michael, often giving Michael orders and expecting them to be carried out.
 * Twiki from Buck Rogers in the 25th Century. He may not have any internal tools installed, but any droid who can operate a fighter craft designed for humans and do it well in combat is not to be underestimated.
 * The second season introduced Crichton, a taller, newer model of robot with an uppity and condescending personality. He was more a "buddy" to Goodfellow than Buck.
 * The original Battlestar Galactica had a robotic dog daggit, which was mostly a Replacement Goldfish but occasionally proved useful for crawling through ductwork or whatever. It had artificial fur and the most obnoxious synthetic bark imaginable.
 * Cy, from Galactica 1980, in fact he's often viewed as the only good thing about it.
 * LazyTown's Robbie Rotten has his "little robot hound".


 * Several Power Rangers seasons have featured these. Mighty Morphin Power Rangers had Zordon's robot buddy Alpha 5 (which is replaced by Alpha 6 as of Turbo), Power Rangers Time Force had the robotic owl Circuit (known as TAC in its source show, Mirai Sentai Timeranger), and Power Rangers SPD had robot dog RIC (which was known as Murphy in Tokusou Sentai Dekaranger) who can turn into a heavy duty laser cannon.
 * Other Super Sentai shows also have their share of Robot Buddies. Just to mention a few, we have IC in Denshi Sentai Denziman, Mag in Choushinsei Flashman, Colon in Choujuu Sentai Liveman, DaiGoyou in Samurai Sentai Shinkenger, Datas in Tensou Sentai Goseiger and Navi in Kaizoku Sentai Gokaiger.
 * Tokumei Sentai Gobusters deserves special mention, as instead of just one Robot Buddy for the team, each Buster has their own "Buddyroid" partner.
 * Craig Ferguson has a robotic co-host, Geoff, in The Late Late Show.
 * Recent Kamen Rider series have started adding very collectible little transforming robots, though they're less full characters and more intelligent gadgets. Kamen Rider Double had various robot gadgets, Kamen Rider OOO had robot soda cans, and Kamen Rider Fourze has robot fast food.
 * Romford in Pixelface.

Video Games

 * In Disgaea: Hour of Darkness, the cliche superhero Captain Gordon, Defender of Earth comes complete with the Robot Buddy Thursday, who fits the description right down to having a self-sacrifice attack named Arigato Roboto ("Thank you, Robot").
 * Incidentally, his character type is not Robot Buddy. It's Invincible Robot/Super Robot.
 * Clank from the Ratchet and Clank series, although he's usually more well-grounded than Ratchet.
 * No list of Robot Buddies would be complete without Floyd from the Infocom Interactive Fiction game Planetfall, called (by those who played the game) one of the most endearing and memorable characters in game history.
 * Joey from Beneath a Steel Sky is the main character's robot buddy. He's also a bit of a Snarky Non-Human Sidekick in that he enjoys the company of humans, but frequently mocks their frailties and thoughtlessness. He is also rather versatile, able to be transferred to a different robotic body when his circuit board is placed into it.
 * Dog (also written as 'D 0 G') from Half-Life 2, a giant, gorilla-shaped robot who throws vans around, beats the snot out of Striders, and communicates via beeps and other robotic noises.
 * Automatons in Final Fantasy XI, while indeed a puppet for the Puppetmaster class, seem to possess unique thoughts of their own, and in at least two cases, personalities! Cardians, which are the pride and joy of Windurst, are a lot less rigid compared to Automatons. Hell, one cutscene has a Cardian trying to look for an EXP party!
 * Robo from Chrono Trigger. He manages to get himself totaled within minutes of his first appearance, though it's a Heroic BSOD rather than a Heroic Sacrifice. Once the Gadgeteer Genius has her way, he (apparently) continues to serve the party with technology-based attacks and futuristic knowledge.
 * Pipo from Overblood.
 * The protagonist of Chibi-Robo! is a Robot Buddy to all of the inhabitants of the house (And I mean ALL), but what makes this even more interesting is that HE has his own Robot Buddy, Telly Vision, who flies around giving Chibi advice and speaking for him in cases where the player has to say something other than "yes" or "no".
 * In Snatcher, we have Metal Gear Mk. II (named and modeled after the eponymous mecha Metal Gear), Gillian's walking Forensics Lab, and Robot Buddy. Unlike most examples of the trope, although loyal to Gillian, Metal does not hesitate to call Gillian out on some of his questionable behavior, and insult him semi-regularly. This little robot buddy was transplanted into Metal Gear Solid 4.
 * The Robot Sentry, while only active for about one and a half levels in Doom 3, works like this, its beeps and boops and overall design being a cross between a cockroach and a puppy.
 * PROXY, Starkiller's holodroid companion from The Force Unleashed, fits the bill pretty well, up to and including . However, he also possesses the added distinction of being programmed to try and kill his master periodically, as a form of training.
 * Befitting a Star Wars game, T3-M4 and HK-47 are respectively the R2-D2 and C-3PO of Knights of the Old Republic (if C-3PO were homicidally insane, that is and R2-D2 is a wisecracking robot who outwits the homicidally insane robot). In the second game, they are joined by G0-T0, the personal droid of crime lord Goto,
 * G0-T0 is more of a chessmaster than a robot buddy. His miniature counterpart on the other hand...
 * The Dinosaur Capture Team from Zoo Tycoon 2: Extinct Animals have their own Robot Buddy, who runs around in the open distracting the tyrannosaurus while the Team's human members sneak up on it.
 * The Claptraps in Borderlands, who give you reminders of new missions and are often seen dancing in the cities.
 * Portal 2 gives you the absentminded but chatty and mostly-helpful Wheatley, voiced by Stephen Merchant, for the first act of the game. Then he
 * In Epic Mickey, Oswald the Lucky Rabbit has the Mad Doctor build him animatronic versions of Mickey Mouse's friends, as he wants Mickey's life for himself.
 * R.O.B., the Robotic Operating Buddy fits this trope In Name Only.
 * Actually something of a subversion. Nintendo understood how this trope works, and thought that R.O.B. could convince retailers that the NES was a toy instead of a video game system. It worked.
 * Descent II and III gave players the Guidebot, a robotic tour guide with an assortment of cute sounds and the ability to name him (or her?) for that extra love.
 * In the Fallout series, the Mr. Handy is a customizable line of robot buddies.
 * Fallout: New Vegas gives us ED-E the recruitable Robot Buddy, Rex might count too, though he's only half a robot.
 * Fallout 4 has the Automatron DLC, which allows you to create your own Robot Buddies.
 * Mass Effect 2 has Legion, who manages to be one of the game's two or three sane individuals (for a sufficiently loose definition of individual). It is something of a Warrior Poet who makes an effort to explain the culture and ethics of the geth, who were previously assumed to be Exclusively Evil, with partial success.
 * It also features EDI, who, although not a robot, is an AI that  In Mass Effect 3, in fact  Seeing as she also is constantly in contact with the player, she feels just like this trope. Arguably one of the best subversions of A.I. Is a Crapshoot.
 * PAL-18 from Anachronox
 * Marcie from Final Fantasy Adventure. He could be used to restore MP when you use the Ask feature.
 * Clank, Ratchet's Hypercompetent Sidekick in Ratchet & Clank.

Web Comics

 * Robot (real name Seraph Thirteen) in Gunnerkrigg Court. He's not had much of a good time since his first appearance; he gets Later, he becomes a revolutionary and starts a
 * Pintsize from Questionable Content is an anthro-PC. We later see other models, including Apple and Linux-based versions.
 * Ethan manufactures one out of his Xbox in Ctrl+Alt+Del.
 * Played with in Deisel Sweeties, where two of the characters in an ensemble cast happen to be robots. Also, the toaster is apparently self-aware.
 * Sam's loyal companion, Helix, from Freefall fits this trope very nicely. Then again, most of the characters in this web comic are robots, so it might be a little odder to find a non-Robot Buddy.
 * Ennesby from Schlock Mercenary isn't so much loyal to the Toughs as he is interested in working for them, as a "free" AI, but especially for the titular amorph he does play the "buddy" part of this trope now and then.
 * And then there's Tenzy hanging out with Captain Landon. Oh, and she did not only built, but designed his prosthesis and (apparently) her flying unit herself, too. Formerly but another stupid potato-gun before its AI was upgraded twice over, thoroughly enough to officially count as fully sapient and be able to use high-end construction nanotech in various ways entirely unintended by the original manufacturer.
 * The Inexplicable Adventures of Bob has Roofus the roof-repair robot. Molly didn't intend for him to be sentient, and it becomes a significant problem for the characters to figure out what to do with him when they realize he is. He ends up going to Stay with the Aliens, since they have more experience with this sort of thing. Roofus is nice enough, a complete innocent, and enormously strong... Just don't destroy a roof he's just finished fixing.
 * Triangle from Walking City - an old mining robot Lariat found at a junkyard and mostly fixed.
 * Times Like This: The ever-versatile Nicki. (Well, almost ever-versatile. She's not a sexbot.)

Western Animation
"Fry (about Bender): On more than one occasion he actually stole my blood."
 * Roboto from the second He-Man and the Masters of the Universe.
 * And before anybody asks, NOT in the first TV series, where he's more like a guest star with only one appearance. If he is or not a Robot Buddy in the original minicomics is discussable.
 * The Attack Track from the original series would count: an armored, all-terrain vehicle with an on-board A.I.
 * Brainiac 5 in the animated series Legion of Super-Heroes (but not the original comics, where he's an organic alien).
 * Inversion: The Robot Buddy from My Life as a Teenage Robot is not a sidekick, but the Action Girl main character. She has a few human buddies.
 * X-5, Betty's snarky robot assistant in Atomic Betty.
 * Carl in Meet the Robinsons.
 * Inspector Gadget is his own robot buddy. He's got everything he might ever need at his fingertips, and all he needs is someone who's paying attention to hang around and tell him.
 * Gadget and the Gadgetinis, the titular Gadgetinis are played straight Robot Buddies, both working with Gadget and taking over the role Brain previously played as Penny's agents to save Gadget from himself.
 * Bender on Futurama is both the best Robot Buddy ever to Fry, and the worst Robot Buddy ever.
 * "I don't want anyone thinking we're robosexuals."
 * Before saying the above in the pilot episode, Bender asks Fry, "You really want a robot for a friend?" to which Fry replies, "Yeah, ever since I was six."


 * Ironically, in the season five episode Proposition Infinity he gets involved with Amy and lobbies in favor of robosexual marriage.
 * In 1980s cartoon, M.A.S.K., T-Bob is Robot Buddy for Scott Tracker.
 * XR from Buzz Lightyear of Star Command is a team buddy.
 * Blue Falcon's best buddy, Dynomutt, the Dog Wonder.
 * H.E.L.P.eR from The Venture Brothers certainly qualifies complete with a dash of The Unintelligible and both The Chew Toy and The Woobie.
 * Jimmy Neutron's mechanical canine, Goddard.

 * The latest Care Bears TV series, Adventures in Care-a-Lot, features a robot buddy in Wingnut, former minion of the Harmless Villain, Grizzle.
 * Speed Buggy.
 * Max Steel has Cytro.
 * Bang.
 * A rare case of a Robot Buddy for a villain was Mule, an assistant to the Egomaniac Hunter Safari Joe in the original Thundercats. Mule was the typical, cute robot, resembling a miniature train, and was able to analyze whatever quarry Joe wanted to go after, and was loyal, despite Joe treating him like garbage. However, when Lion-O defeated the villain, the heroes let him go on the condition he promise never to hunt again, and Panthro reprogrammed Mule so he'd make sure Joe kept his promise - Mule seemed quite happy with his new programming.
 * Also, Captain Cracker was a robot Space Pirate who had a robotic parrot, making him a robot with his own Robot Buddy. Not that the parrot was very loyal; after Cracker and his crew were arrested, it suggested Mandora have Cracker boiled in oil.
 * One shot villain the Gamemaster from G.I. Joe: A Real American Hero had a monkey-like Robot Buddy named Koko.

Anime and Manga

 * Mechazawa from Cromartie High School. Although it seems almost no one in the school realizes he's a robot, or they just decide never to mention it. As far as most of the cast is concerned, he's just a normal delinquent with a really hard body. He may be more of a case of a robot with human buddies, as he's looked up to by just about the whole school. Looks basically like an oil drum with skinny robot limbs and eyes attached.

Live Action TV

 * The device was parodied on Friends when Joey got the lead in an awful show called Mac and C.H.E.E.S.E. about a cop who fights crime with his wisecracking Robot Buddy.

Anime and Manga

 * NB from Tenchi Muyo GXP, who is not only a voyeuristic Dirty Old Man, but the Author Avatar for the series' director, Nabeshin of Excel Saga fame.

Comic Books

 * Aaron Stack (formerly Machine Man) in Warren Ellis' fight comic Nextwave, a Do-Anything Robot who evidently comes with a constantly bitch and moan feature.
 * L-Ron from the late '80s/early '90s iteration of Justice League of America was a sarcastic robot, formerly the majordomo of an interstellar tyrant Corrupt Corporate Executive who defected to Earth and became the personal assistant to the League's smug financial backer, Max Lord, whom he constantly jabbed with sardonic barbs. He was cordial towards the rest of the team, though, if a bit acerbic. After this version of the League disbanded, L-Ron wound up working the drive-thru at a fast food joint.

Film

 * Dot Matrix in Spaceballs, a Robot Nag rather than a Robot Buddy.

Literature

 * Marvin the Paranoid Android from all incarnations of The Hitchhiker's Guide to the Galaxy, who hates his owners, his creators, himself, and the whole of existence, and never stops telling this to anyone who will listen. (Presumably the marketing division of the Sirius Cybernetics Corporation was referring to a different sort of robot when it advertised "Your Plastic Pal Who's Fun To Be With!") On at least two occasions Marvin was able to stop the opposing forces by linking into their computer system, making it depressed or even suicidal.
 * Daneel Olivaw in Isaac Asimov's Robot novels. Daneel plays the trope straight, but his human companion Elijah Baley wants nothing to do with any of those despicable robots, at least not till fairly late.

Live Action TV

 * Eve in Mann and Machine is all but human in everything but physical limits and life experience, although her predecessor as Bobby's partner certainly fit this trope to a T.
 * Red Dwarf: Kryten is a cheerful, friendly, helpful domestic robot. Unfortunately he's just the teensiest bit neurotic, has a fixation with cleanliness that borders on obsessive-compulsive, and lives in constant fear of rejection. He's also not particularly good at anything except cooking and cleaning.
 * And providing exposition.
 * Lexx: 790 is a disembodied robot head who is a Deadpan Snarker as well as a complete and utter Jerkass to anyone who isn't Xev - especially Stan, and on several occasions he comes across as completely psychotic.
 * Such as when he blew up . 100% knowingly and deliberately.

Video Games

 * Curly in Cave Story, given Quote himself is a robot.

Web Comics

 * Many characters in Questionable Content have "Anthro PCs"—Anthropromorphic Personal Computers; antisocial and psychotic little robots that don't like taking orders and engage every electrical appliance in sight sexually, sort of like persocoms with attitudes. Of course, this may just be the main character's Anthro PC.
 * It was revealed in a short series of strips to be a side-effect of his region settings. It got switched to British, and he spouted a top-hat and monocle, and started acting like a butler. His normal setting, with the psychosis and raunchiness is American. It was never fully explored how much was actual change, and how much was Pintsize screwing with people, though.
 * Recently the strip has introduced Winslow (a Mac Anthro PC) and Momo (a Sony Anthro PC) who are both quite friendly and make nice foils to Pintsize's hijinx, making his attitude possibly due to his model. There is also PT410x (a Linux Anthro PC), who is an arrogant dick constantly jabbering about how "Closed-source software is slavery" (he goes by his serial number rather than a "human-coined SLAVE NAME" for this reason), and crazy conspiracy theories.
 * The above description also works well for Div from Penny Arcade, especially, and disturbingly, as regards sex (why did Div need condoms??) but the list of his attributes must also include: alcoholic, misogynistic/homophobic, alcoholic again, and very, very verbally abusive.
 * Not to mention the infamous Fruitf**ker.
 * Do NOT think about what it does. On a more humorous side, in the new game it appears to be the main villain.
 * Robot, alias XR-7439-Q, is less 'buddy' and more 'long-suffering indentured slave' who must obey Captain Zap, even though he's an Idiot Hero whom Robot despises. Zap, for his part, still sees and treats Robot as if he really were a typical sci-fi robot buddy.
 * UNA Frontiers gives you Cyberna and Shiratz, who are subtle subversions of the trope. The former is an intended human/dolphin interface, the latter an ancient alien probe in the shape of a horse and realistic enough to pass a cursory veterinary inspection. They become loyal friends and allies, but are definitely not subservient.
 * Mr. Bix of Red Meat is a subversion. A vomiting, kid-microwaving subversion.

Western Animation
"Fry: On more than one occasion, he actually stole my blood."
 * The concept of a robot buddy was reversed for the whole concept of Bender from Futurama, who shows the exact opposite of everything that makes a Robot Buddy (while ironically still being a buddy). He did, however, perform a Heroic Sacrifice to the book.
 * Except that it was All Just a Dream.
 * Don't forget why they call him "Bender the Magnificent"! Where'd everybody go?

"Morgan: He was a bad robot. Fry: No, he was a bad friend, and I want him back!"
 * When Morgan Proctor removes Bender's personality and puts it on a disk, Fry protests vehemently.


 * GIR on Invader Zim is another subversion of the Robot Buddy who is actually The Ditz.
 * The original Transformers series had a human buddy in Spike, as the robots were the stars of the show. However, some of the other shows play this straight.
 * Transformers Animated is somewhere in the middle: some of them act as Robot Buddies of Sari (mostly Bumblebee and Bulkhead), but they do plenty on their own, and there are quite a few episodes where she has little or no effect on the plot. And then it turns out
 * The Minicons were little Robot Buddies of other robots.
 * The Larry 3000 from Time Squad is of the Deadpan Snarker variety of Robot Buddies.
