Easily Detachable Robot Parts

Go To

Some robots are apparently constructed of easily detached (and easily reconnected) parts. An arm fell off? The head fell off? No sweat, just screw or push it back on, since they usually are as easy to connect as LEGO. Use it as a weapon, why don't you? Sometimes it appears that each of their parts is self-sufficient and can function on its own.

This is generally justified by having the power source and CPU being the only real parts that matter; everything else can be repaired or replaced. Kinda makes sense when you look at a computer, which will continue running as usual after you unplug everything but the power cord. That doesn't mean it makes sense every time.

Can get a bit ridiculous if the robot is easily rebuilt after things like explosions, which logically should misshape the parts that reconnect. To go to the computer analogy, your PC will work if you take anything but the power cord out, but it won't work that well if you do something like shoot it with a shotgun.

    Anime and Manga 
  • The eponymous robot of Dai-Guard tends to lose an arm in every fight. This is weaponized by Akagi in the third episode, and later elevated to an actual function of the machine, with its advanced weaponry replacing one or both of its arms.
  • A lot of Mobile Suit Gundam series love to do this, especially if the mechs use a Core Block System:
    • In Mobile Suit Gundam 0083: Stardust Memory, Kou Uraki separates the GP-01 Fb's lower torso from its upper torso to escape the Val Varo and land a killing blow.
    • In Mobile Suit Victory Gundam, the titular mech can actually launch its components, the Top Fighter (its arms and chest) and Bottom Fighter (lower torso and legs) at opponents. Justified as the League Militaire have TONS of those things.
    • In ∀ Gundam, the Turn X has this as one of its primary gimmicks: the head and limbs can all detach from the main body and propel themselves on their own, allowing the Turn X to strike from unexpected directions. The pieces can then just as easily snap back into place.
    • In Mobile Suit Gundam SEED Destiny, Shinn Asuka uses this expertly in his fight with Kira Yamato between the Impulse and the Freedom, including the same separating at the waist maneuver Kou pulled off and even launching the top half of the Force Impulse at the Freedom and making it explode!
  • Code Geass's Knightmare Frames have arms capable of being detached, handy if they're trapped or damaged to the point of uselessness.
  • In Kotetsu Jeeg, Jeeg's head and limbs are held together by powerful magnetic fields in the first place, so detaching them is easy.

    Comic Books 
  • In the short-lived 1980's Archie Comics series ManTech, both the cyborg good guys and the robot bad guys have modular parts. The comic was based on a toy line that had this characteristic.
  • Extremely common in Sonic the Hedgehog (Archie Comics). More so than in other adaptations, where the robots tend to have less personality.
  • ABC Warriors: the ABC often display this, with one of them even removing his head when he takes a bath.
  • Robotman from Doom Patrol, although his parts weren't designed to come off. His readiness to discard body parts at the first sign of trouble is actually a symptom of self-destructive rejection of his artificial body and severe depression.

    Films — Animation 
  • The Iron Giant is so modular that individual screws are intelligent enough to track down the rest of the body if misplaced.
  • WALL•E
    • WALL•E. Apparently, he's specifically designed so he can replace any of his damaged parts himself, with absolutely everything being modular. Justified: he is an industrial robot designed to take care of himself for long periods of time, and the only one that is still activated, so he's got plenty of spare parts... The WALL•E industrial models likely lasted a while, but our protagonist was the only robot of his model that last this long, due to being a notch smarter and more curious than the rest, and figuring out how to repair himself using the corpses of his brethren.
    • EVE's head and arms are even more easily detachable, since they just float alongside her body, as if they're connected by some kind of energy field. This creates some confusion for WALL•E in the repair ward.
  • Played for Drama in Robots; Fender has been shown losing his head, arms, and legs and still be okay. However, this is actually a sign that he's an outmoded robot (which usually end up going to the scrap heap), and since his parts are discontinued, putting him back together is tricky.

    Films — Live-Action 
  • Star Wars:
    • C-3PO, of course. In A New Hope an arm comes off and is easily reconnected. In The Empire Strikes Back, he is dismembered and Chewbacca has to work at reassembly. The first film's novelization indicates that most protocol and translation droids are made this way so that they can take abuse from owners who like to Shoot the Messenger. In Attack of the Clones, C-3PO's head is easily knocked off and re-attached to the wrong body. Then later, the same happens again but in reverse. Which is odd, since no other robots survive having their heads taken off, especially those of the type that C-3PO's parts keep getting swapped with.
    • The gangly B1 battle droids' limbs are attached electromagnetically and can be ripped off with relative ease. In case of sudden power loss, they can even just fall off.
  • Terminator: The T-1000 from Judgment Day and Genisys is a robot, albeit a liquid metal one, with detached parts reverting and being reabsorbed into the main mass.
  • Johnny 5 from Short Circuit (and, presumably, every other SAINT robot) are built like this; each Nova truck is full of parts for them, and Johnny uses them to at different times replace an arm that went dead (which, apparently, was being held on at the shoulder joint by just magnets) and building an entire duplicate to get blown up by the military for him. Justified in that since he's a military model robot he'd have to be easily repairable and moddable, otherwise they'd spend too much time and money in fixing him out on the battlefield.
  • In The Hitchhiker's Guide to the Galaxy (2005), Arthur detaches Marvin's right arm for use as an improvised weapon, despite having no tools handy (unless Ford's towel is that cleverly made).
  • The short film I'm Here is centered around a male robot selflessly giving his love interest his limbs as she accidentally damages hers beyond repair. He can detach them in a matter of seconds with a screwdriver stored in his fingertip.
  • In Ex Machina, Ava easily takes her broken arm off to replace it with a spare.

  • The existence of a robot designed like this was a major plot point in The Naked Sun, a science fiction murder mystery by Isaac Asimov.
  • Vuffi Raa from the The Lando Calrissian Adventures can detach his five tentacles from his "body" and have them do tasks by themselves. The tentacles even have enough individual intelligence to operate starship guns, thus allowing Vuffi Raa to get around his Thou Shalt Not Kill programming.
  • The Murderbot Diaries. In Network Effect the title character, a cyborg, finds itself suspended upside-down over a pit with its arms taunt so it can't break free. Murderbot detaches a hand which involves individually disconnecting circuits and tearing loose some flesh and nerves (fortunately it can dial down its pain sensors), then walking the hand by the fingers up onto the arm, which is then torn free of its cuff whereupon the hand is reattached. Murderbot is then easily able to break the other cuffs. The main risk involved dropping its hand during all this, which would have left Murderbot screwed.
  • Almost all of the cast of The Railway Series are well... steam locomotives, meaning parts are removed and replaced regularly on them all the time. Sure most of the parts removed happen on accident such as Edward's drive rod snapping or Skarloey losing a suspension spring... but send them to the shop and slap a new part on and they are back out on the road good as new.

    Live Action TV 
  • Data (and by extension Lore) on Star Trek: The Next Generation. Although Data is shown to be extremely strong and durable under most circumstances we are shown in one episode that his limbs can detach with a simple twist.
    • Later episodes show that his entire body is detachable and his head (if disconnected properly) can function independently.
  • Kryten from Red Dwarf has body parts get removed frequently, usually for comedic purposes.
  • In the Doctor Who episode "The Pandorica Opens", Amy and the Doctor encounter a Cyberman who has his head and arm removed and all three parts are capable of acting independently.
  • Jimmy the Robot from The Aquabats! Super Show! can remote control his detachable hands.
    • That's not all he can do, either. At one point in the very first episode, he gets one of his arms ripped off by a giant ant, and then proceeds to grab it and start beating the snot out of said ant with his own arm ala Toy Story. The next shot shows him popping the arm back into place with no ill effects. He also uses one of his hands as a grenade at one point (and yes, before you ask, he says "How about a hand grenade?" before detonating it), but since his original hand exploded he simply replaces it with a spare that rises out of his wrist stump.
    • Exploited by Eaglebones Falconhawk in Return of the Aquabats. An old villain, Ronmarc, has started bullying Crash so Eaglebones unscrews Jimmy's head to state that "he's broken" and to set off Crash's Berserk Button.
  • Mystery Science Theater 3000:
    • A gag that frequently appeared in the earlier seasons would have Joel rip one of Crow's arms off in annoyance every time Crow made a joke that went too far. The arm would usually be back in place by the next host segment with little to no discussion.
    • Tom Servo's dome would also pop off from time to time, usually by means of a genuine accident. Rather than kill the take, it was often turned into a Throw It In! by having Servo scream in alarm when it happened.
  • This happens at least twice in Power Rangers and quite possibly a third time.
    • The first confirmed case is in Mighy Morphin Power Rangers season 3.5, when Goldar and Rito Repulso go into the basement of the Command Center. They walk past a box of what is obviously an Alpha series robot disassembled and in a box. This indicates that the Alpha series robots, like Alphas 5, 6, and 7 that we see in the show can be disassembled in this way, though there is no indication that they can interact with the world around them while disassembled.
    • The second confirmed case is in Power Rangers Operation Overdrive in which Mack, the team's Red Ranger, is an android. Due to a case of Mack Hartford catching a virus during a mission (the Irony of rather funny), Andrew Hartford, the team's mentor, has to detach his son/creation's head to help get rid of the virus. The freakout that Mack has when he wakes up makes the scene horrifically hilarious.
    • The possible time actually happens in between these two shows, during the second half of Power Rangers Turbo, when the Turbo team is replaced by androids identical to the second Turbo team (TJ, Cassie, Carlos, and Ashley, as well as Justin Stewart, the season's Blue Ranger). While it's not indicated that they have completely removable body parts, the fact that Ashley's android counterpart is shown as being able to open an access panel in her arm to fix something indicates that it might be possible, as well as there being an access panel in Justin's android counterpart.

  • No.3ll3 of The Adventure Zone: Balance undergoes an upgrade by placing her soul conduit into a new, larger body, and then attaching additional limbs to it.

    Video Games 
  • Alisa Bosconovitch of Tekken 6 is a Robot Girl with a detachable head. An exploding detachable head. She even has alternate intro and victory poses where she's either carrying her head or it falls off while she's talking.
  • In Metal Fatigue, the combot parts of all factions (murderous precursors included) are perfectly compatible with each other. Lopped off the axe-toting arm of your opponent with a katana? Eject your useless energy shield arm out of its socket and graft his weapon on in mid-melee. Humiliation ensues.
  • Cyborg Justice was a great example of this; among your various hand-to-hand combat moves, you could yank off your opponents' arms and replace your own with theirs; you could also yank their torso off their legs, absorb their life force, and then steal their legs too. Nothing says pwnage like stealing all your parts. Actually, there's a bit of a subversion, as it takes some effort on the part of your cyborg to rip off their arm. Oddly enough, tearing them in half afterward plays it entirely straight.
  • Etrian Odyssey III: The Drowned City: The Gatekeeper, an automaton built by the Deep Ones and the boss of Molten Caves, has this capacity. During battle, it is capable of detaching its head and its upper body, making it so they can attack separately.
  • Mega Man:
    • In the "Day of Sigma" movie in Mega Man: Maverick Hunter X, X at one point simply drops his buster off, then it turns back into his forearm by itself.
    • Both Mega Man 7's Junk Man and Mega Man Zero 4's Mino Magnus are good examples. Junk Man, as his name suggests, was a robot made out of spare parts and assorted trash held together by electromagnetic forces. Said forces can be easily disrupted by Cloud Man weapons Thunder Bolt causing the trash titan to fall apart. Mino Magnus was the boss of the Magnetic Zone and could generate huge amounts of electromagnetic power. In battle, Magnus used said power to separate his body into five parts, attacking Zero with a rather complex pattern of movements.
  • In the Angband Steampunk variant Steamband, the player races Automata and Steam-Mecha use robot parts in lieu of some clothing items, and mostly advance by finding or buying better versions of these. Thus, various types of heads, torsos, arms, and legs are entirely swappable. (This also means that the lack of all of these won't prevent a character from certain basic functioning...) Given the extreme speed at which certain monster automata can reproduce, they may be designed along similar lines.
  • In co-op in Portal 2 one of the gestures involves removing your partner's head.
  • In Space Quest VI: Roger Wilco in the Spinal Frontier, Roger asks Circuit Sydney, the resident android on the DeepShip 86, to lend him his eye and an arm. Sydney is a little reluctant at first, but Roger promises to return them. They come off easily.
  • In MySims, Makoto, despite being a typical high school girl, loses her arms from time to time, including, in MySims Agents, during her "Prom Date" mission if you have her do "The Robot" instead of the waltz for the final dance.
    • In MySims Kingdom, Tobor is disassembled in a rocket explosion; your first two missions on Rocket Reef involve collecting his pieces so he can put himself back together. The second of these involves guiding his legs — which can walk by themselves — over to him. On the whole, he comes out of the experience a little better than before.
  • The Legend of Zelda:
    • From Skyward Sword, the boss Koloktos: throughout the battle, you use a whip to pull its arms apart, and then you swing at the Heart Drive with one of its dropped swords. While, after a brief amount of time, it is able to use some sort of energy to reattach its arms, it is unable to repair the damage on the cage it uses to protect the Heart Drive.
    • From Tears of the Kingdom, the Flux Constructs are cube-like objects filled with energy that use said energy to tether other inactive cubes into various forms. Link's Ultrahand can be used to remove the smaller cubes easily, but ripping out the core to attack it requires a dedicated effort.
  • Five Nights at Freddy's:
    • Toy Foxy in Five Nights at Freddy's 2 was intended to replace the original Foxy as a normal animatronic pirate, but the kids kept tearing it apart. Reassembling it is easy enough, but the employees were so sick of doing it after every shift that they just decided to rebrand it "the Mangle" and claim it's a "built-it-yourself" attraction from now on. This might not be a problem if A) the robots weren't secretly self-aware, and B) Mangle's messed-up state wasn't somehow more deadly.
    • Toy Chica removes parts of her face when she's active for no reason other than making herself look scarier.
    • Recorded tapes in Five Nights at Freddy's 3 reveal that Fazbear Entertainment created animatronics that could also be worn as suits by locking the endoskeleton parts in different areas around the suit. And they could be put back together and work just fine. Of course, the easily detachable parts wouldn't easily stay detached, as William Afton found out...
    • In Five Nights at Freddy's: Sister Location, Circus Baby, Ballora, Funtime Foxy and Funtime Freddy break themselves apart and come together as one entity known as Ennard. This, surprisingly, has no effect on their ability to function. Come Freddy Fazbear's Pizzeria Simulator, and it's still functional (as Molten Freddy), even after ejecting Baby some time ago.
  • Invoked in Knights of the Old Republic when HK-47 suggests doing this as a way to rescue a person.
    HK-47: Suggestion: Perhaps we could dismember the organic? It would make it easier for transport to the surface.
    Twi'lek: Hey! can't just rip me to pieces! I'll die!
    HK-47: Amendment: I did forget that. Stupid, frail, non-compartmentalized organic meatbags!

  • Helix from Freefall. All his limbs - head included - are easily detachable and modular so if he loses a piece, you can just stick it right back in the slot - since he's an industrial robot designed for carrying heavy objects, it makes sense - being able to easily shed a limb ensures that he won't easily be pinned under a fallen object, and user-friendly reattachment makes repairs a breeze. (The reassembly is idiot-proof, though definitely not Sam-proof.) Unsurprisingly, he gets taken apart a lot, but he doesn't really mind - it's usually Florence who puts him back together again (though she's usually also the one who took him apart in the first place), and being the brilliant engineer that she is, she usually puts him back together BETTER than he was.
  • Pintsize from Questionable Content is held together in much the same manner as Helix, with contained-field magnetics that allows him to be put together however you want. And also pulled apart without incurring permanent damage.
    • Including being able to pull his own head off and throw it at someone he's too short to Dope Slap.
  • The robots from Gunnerkrigg Court seem to be this, as Antimony (who, by her own admission, doesn't know the first thing about robotics) was able to reconstruct Robot S13 from a box of parts (i.e. torso, arms, legs, etc.). On the other hand, actual damage to these parts is not so easy to repair.
  • In The Inexplicable Adventures of Bob!, after Fructose Riboflavin deactivates his robot guard to escape from prison, he removes the guard's Arm Cannon to use as a gun. It's too big for him to cart around, so he sets it on a wheeled tripod.

    Western Animation 
  • Bender from Futurama has spontaneously popped off virtually every piece of himself (head, arms, legs, fingers), and is pretty much hollow. Taken to absurd levels and lampshaded as early as the first episode: A scene opens with Bender using one arm to put his other arm on, with the view so close that we can only see the act itself. Then the arm that was just screwed in picks up the first arm, and the camera pans to the second arm attaching the first to his other shoulder. Fry then remarks that he has no idea how that was possible.
  • Played for laughs in a torture scene in The Venture Brothers The Monarch's henchmen try to rough Helper up but knock off his head, making them realize there isn't much they can do to the robot.
  • Cyborg of Teen Titans (2003) can casually pop off either of his arms. Despite this, one episode showed his hand as being organic beneath the exterior.
  • Jenny Wakeman (XJ9) from My Life as a Teenage Robot frequently has body parts taken off and easily put back on (or self-reassemble), although she does require a lynchpin to hold her body together. Most of the time this actually takes pretty severe physical trauma, but one of the first couple episodes has Brad accidentally tear her arm off when trying to get her to come outside. XJ3, on the other hand, is explicitly shown to have parts fall off at the drop of a hat, which is the main reason she's a Flawed Prototype.
  • Larry 3000 from Time Squad.
  • The Transformers lose body parts all the time and they are simply re-attachable. It caused problems in Beast Wars especially, where so many characters get utterly smashed, dismembered, and mangulated for comedy purposes that when someone is Killed Off for Real, the reaction is less "Oh, no!" and more "wait a sec, didn't Airazor turn Terrorsaur into robo-confetti, only for him to be back to normal by the end of the episode? Dinobot didn't suffer half the damage Waspinator does every week!"
    • Hell - in one episode, Inferno was vaporized, only to return in the next one with minimal damage.
    • The Junkions are the epitome of this.
    • The live-action movieverse seems to be the only incarnation of TF where having your head removed is more than an inconvenience.
      • Though Bumblebee's legs were reattached before the end credits of the first movie, so...
    • The funniest part is that nowadays, the actual toys are made like this to prevent them from permanently breaking if you stress a certain part the wrong way.
  • This is the entire purpose of XR in Buzz Lightyear of Star Command. In the pilot movie, he was built following the death of Buzz's partner. The idea was to give Buzz a new partner that could be easily reassembled. However, he was rebuilt while the techs were effectively off their meds thanks to temporarily losing their Hive Mind, resulting in a rather bizarre personality and unusual components from then on.
  • The Adventures of Jimmy Neutron, Boy Genius: Goddard, Jimmy's robotic pet dog. Due to an error in programming, when given the command "Play Dead", Goddard explodes into pieces...only for the pieces to reform back into the same shape a few seconds later. How a single part of Goddard doesn't warp or break from internal combustion is beyond logic, but it makes for a pretty impressive dog trick.
