Retractable Weapon

Go To

So you have a rather long weapon, and you don't have the Bag of Holding or any sort of Hammerspace to store and conceal it. What to do? Make it retractable, thus concealing it and possibly making it small enough to be stored without any problems.

In the 21st century, this trope has had decent overlap with the Carry a Big Stick and Lawman Baton tropes, thanks to the invention of the expandable baton (also known as collapsible, telescopic, extendable, tactical and spring cosh baton). Although it's not exactly exclusive to law-enforcement or security detail, as these can also be seen in the hands of civilians for self-defense, or even criminals!

Sub-Trope of Impossibly Compact Folding. Typically, any type of Blade Below the Shoulder, Laser Blade, Sinister Switchblade, Telescoping Staff, or Pile Bunker is this trope. Compare Shapeshifter Weapon, where a character that can shapeshift can create many weapons from their body, Morph Weapon which is a weapon that can take different forms and Person of Holding. See also Idiosyncratic Mecha Storage, IKEA Weaponry, Fuuma Shuriken, Bifurcated Weapon Sleep-Mode Size, and Wolverine Claws. Contrast with Collapsible Helmet.

    Comic Books 
  • X-Men:
  • Pops up quite a bit in the Batman franchise, mostly thanks to the fact that most of the Bat Family are a technological geniuses and that Bruce has the money to spend on creating all sorts of gadgets that they an easily store in their utility belts.
  • Spoofed in Asterix in Corsica. The Weapon of Choice of every Corsican is a wristblade, which they're not shy to show for intimidation purposes. For the big battle at the end, they happen to have also retractable swords and even retractable spears — doing the exact same sound as the wristblades.

    Film — Live-Action 
  • The expanding baseball bat used by Griff Tannen in Back to the Future Part II.
  • Demon of the Lute: Yuan Fei the swordsman uses a broadsword whose blade can retract to less than two inches, and extends itself to regular length when drawn.
  • Hellboy: Kroenen's arm blades in the opening scene.

  • Marvel Cinematic Universe:
  • The Mummy Returns has a retractable spear/sceptre.
  • The New Legend of Shaolin: Hung Hei-kwun, the protagonist played by Jet Li, uses a retractable spear that can be folded to the size of a calligraphy brush. In the opening fight he triggers an extending mechanism that allows this spear to skewer 3 ninjas at the same time.

  • The Predator has retractable wrist-blades. The sequel Predator 2 adds a retractable staff/spear to the species' arsenal.
  • RoboCop has the terminal strip. It's more of an Improvised Weapon. Normally, the terminal strip is used for interacting with data ports and downloading information from the police database, but he occasionally uses it for offing criminals.
  • Star Trek (2009): Sulu's katana.
  • The lightsabers from Star Wars look like small flashlights when not activated.

  • In the original Underworld movie, werewolf leader Lucian carries a very long, very spiffy retractable arm blade hidden in the right sleeve of his Badass Longcoat. The mechanism to move and store the blade is never shown, which is probably for the better since the blade alone is longer than his forearm, making the whole design pretty much useless for everyday use if not for the Rule of Cool.

  • One of the weapons in Cretan Chronicles is a twig that can extend itself into a [[Blade on a Stick spear, which while increases combat ability. Is only able to be used once.
  • Larry Niven's Known Space: variable swords (Monofilament wire reinforced with a stasis field) extend from and retract into the handle, their state only obvious from the ball at the very tip of the blade to reduce accidents from not knowing where the blade actually is located.

    Live-Action TV 
  • Andromeda: the Force-lance, which can extend to a 2-meter-long quarterstaff.
    • Unusually for this trope, force lances are also frequently used in their collapsed state as guns, and the fact that pointing them would be more difficult than a gun is explained by the use of guided bullets.
  • Angel:
    • The titular character used single retractable arm blades on each forearm—notable in that they were wooden stakes specifically for fighting vampires. He tended not to use them in later series though when the show moved away from its original detective-style.
    • Wesley Wyndam-Price had one in later series after he Took a Level in Badass. Special mention as it could function as an 'assassin' style short blade or fold out into a fully-fledged longsword via an 'unfolding' method that was one of the cooler special effects to appear on the show.
  • Arrow: Oliver Queen has a collapsible compound bow for unexpected social occasions like Nazis from an alternate Earth gatecrashing a wedding.
  • Babylon 5: the Minbari Fighting Pike aka Denn'Bok. Preferred weapon of the Rangers.
  • Doctor Who: In the 2005 reboot onwards, the Doctor's sonic screwdrivers usually have an extending/retracting feature. Eccleston/Tennant's is a sliding mechanism while Smith's has a spring-loaded claw. While this is purely for Rule of Cool, it's sometimes played for Something Else Also Rises laughs.
  • In the The Shannara Chronicles, the High Druid Allanon carries a sword that unfolds from its hilt in a way that doesn't seem entirely possible, but is presumably magic.
  • Ultraviolet (1998). Vaughan's personal weapon is a spring-loaded ice-pick with a spike made from carbon-compound—basically a modern and unobtrusive Wooden Stake.

    Myths & Religion 
  • In Norse Mythology, Thor could shrink down his hammer Mjöllnir so that he could fit it inside his clothes. For this reason, Mjöllnir-shaped pendants are common in that part of the world.
  • Journey to the West: Sun Wukong's iron-banded rod is the quintessential Telescoping Staff, and when not in use, he shrinks it to the size of a toothpick and keeps it behind his ear.

    Tabletop Games 
  • BattleTech: The Retractable Blade is a melee weapon that is Exactly What It Says on the Tin. Though it's not actually a weapon so much as a tool that was added to some battlemechs for use as an Improvised Weapon. There are also some mechs that have fluff regarding some of their weapons being retractable, but this is purely flavor text that has no impact on gameplay.
  • In Shadowrun, retractable claws are available as cyberware and known by the nickname "wolverines". As well as a collapsible staff and the Victorinox memory blade which folds into a belt.
  • Eclipse Phase has the "Flex Cutter" which is a machete made out of a memory polymer that becomes stiff or flexible enough to roll up with the push of a button.
  • Dungeons & Dragons:
    • The Shrink Item spell can be put to this usage, turning weapon into apparently inoffensive trinkets until a command word is spoken. It can also be rendered permanent, although theoretically it doesn't work on magic items.note 
    • The Savage Species splatbook introduces "Hideaway" weapons, which magically fold up on pressing a stub, leaving an inconspicuous and easy-to-hide cylinder fitting in the palm.

    Video Games 
  • Assassin's Creed: The Hidden Blade, the signature weapon of the Assassin Brotherhood.
  • Adam Jensen's arm blades in Deus Ex: Human Revolution, which can come out of his wrists or his elbows.
  • BattleTech: The Hatchetman, added in the Urban Warfare expansion, has an axe in its right arm. When it uses a melee attack, the axe extends out to strike, then folds back up and retracts back into the arm.
  • The weapons in Mass Effect fold up to much smaller sizes when they're not used. Special mention goes to the omni-blades in Mass Effect 3, which literally do not exist until used, as they are flash-forged at the press of a button.
  • Mortal Kombat: Baraka's Tarkata arm blades
  • Jade uses a retractable staff as part of her arsenal in Mortal Kombat.
  • Team Fortress 2: The Spy's butterfly knife.
  • Dishonored: Corvo Attano's collapsible sword.
  • Elite Dangerous has retractable weapons on all ships, as the Frame Shift Drive needs a smooth profile to engage. Other ships will be alerted when you deploy your hardpoints.
  • Popular in Space Engineers; retracting weapons into your ship allows you to hide your ships true capabilities and protect them from damage, but it requires enough internal space for the mechanisms (pistons, rotors) to actually move the weapons about, and it's possible for damage to jam up pistons leading to the nasty situation of a jammed rocket launcher firing straight into the innards of your ship.
  • In the intro video to Battlezone II: Combat Commander, the Voyager 2 space probe is shown to have a pair of machine guns concealed in the body, which will extend out of the body and jettison their concealing covers when the probe detects an incoming threat.
  • Aiden's collapsible baton in Watch_Dogs.
  • Several weapon classes in Monster Hunter are packed up when put away:
    • Heavy Bowguns are usually so big they're carried in a collapsed form. Weapon drawing therefore takes a lot longer because you have to reassemble the weapon.
    • Gunlances and Bows are stored similarly folded in half.
    • Lances and some Insect Glaives telescope into themselves a bit.
    • Switch Axes reconfigure themselves to be as compact as possible.
  • Spaceship weapons in FTL: Faster Than Light slide into the ship's hull when they are not powered.
  • On Final Fantasy XIV magitek weapons often retract into compact forms when not in use.
    • The boss of the dungeon "The Swallow's Compass" Qitian Dasheng is based heavily on Sun Wukong from the Journey to the West example above. Whether he extends or retracts his staff gives away what his next attack will be.
  • Lightning Returns: Final Fantasy XIII: Dual blades fold into themselves when Lightning sticks them to her back. The opening cutscene also shows that her Night Lotus shield can condense to a less obstructive form, although the player never gets to see this in gameplay.

    Web Animation 
  • In RWBY, a lot of weapons are collapsible. Some Fridge Logic is pointed out when discussing Jaune's collapsing shield though:
    Jaune: And it gets smaller, so, when I'm tired of holding it, I can just... put it away.
    Ruby: But, wouldn't it still weigh the same?
    Jaune: [dejected] Yeah, it does...


    Web Original 
  • New Vindicators: The wizard/super-genius Jason Lamperouge crafts a magic sword that can cut through steel and when not in sword form, resembles a small cross (as in two perfectly intersecting lines, not a Christian cross) that he wears on a neckchain. It is called the Pentacle of the Blade and it extends when he speaks the word 'tonedo' which roughly means 'to shear.'

    Western Animation 
  • ReBoot
    • Megabyte has Wolverine Claws in his hand.
    • AndrAIa has a extendable/collapsible trident weapon.
  • Robin in Teen Titans has bo staffs that retract to fit in his utility belt. So does Slade.
  • El Tigre has claws that he can use to grab/attack people from a distance, due to a Variable-Length Chain.
  • Optimus' axe in Transformers: Animated has an extendable shaft.
  • Wakfu:
    • Rubilax isn't so much retractable that size-shifting; its normal form is between the size of a short sword or dagger, but it can turn into a BFS (with Volcanic Veins in option) in a hitch.
    • Some air pirates also have sword-lances that can change size.
  • In ThunderCats (1985) and its 2011 reboot, the Sword of Omens' default size is a dagger/shortsword. When its wielder utters a battle cry to unleash the power of the Eye of Thundera (also known as the Warstone in the reboot), the Sword becomes a longsword. The 2011 reboot explains the Sword's small default size: Mumm-ra destroyed a star system to create the special metal capable of channeling the Warstone's power. When the blacksmith forged the Sword of Plundaar and its matching gauntlet out of it, a bunch of small shards fell in the process. The Sword of Omens and the Claw Gauntlet were forged from those shards.
  • In Motorcity, Mike Chilton has Spark Staff, which emerges from a miniature skull of his. His partner Chuck has a wrist-mounted slingshot that is also this.
  • In Super 4, Alex's sword blade is retractable, being half as long when in its sheath. He once elongates it much further to use as an impromptu perch, although that's in an Imagine Spot.
  • In one of the Treehouse of Horror episodes of The Simpsons, Homer discovers a plot by Kang and Kodos to Take Over the World by impersonating presidential candidates Bill Clinton and Bob Dole. When he threatens to tell everyone, the two "deal with" Homer by revealing a giant device that telescopes ominously towards him... before a tiny nozzle comes out and hoses him down with rum so that nobody will believe him.
  • Dungeons & Dragons (1983): Diana's magic staff can retract to the size of a baton for ease of carrying. She also often uses its telescopic properties to boost her pole jump. It's also self-repairing, so snapping it in two is only a short problem.
  • The Venture Bros.: In the flashbacks showing Brock's Training from Hell under Hunter, one of his first acts of taking him by surprise is... hitting him on the knee with an extendable baton, that also has a large metal mace head mounted onto it.
    Col. Gathers: Are you still ready for anything?
    Brock: Ye-
    Col. Gathers': HWRONG!!!
    (Smacks him on the knee with a mace-headed telescopic baton)
