File:Explosive collar 2808.jpg

The most effective way of keeping slaves in line.


Ms. Bitters: No leaving class without a hall pass, Zim.

Zim: Of course.

[Ms. Bitters places a collar around Zim's neck.]

Ms. Bitters: If you leave school grounds, it will explode.

The government needs a badass special operator for a suicide mission no sane person would undertake. So they recruit a suitably trained prisoner for the job. How do you ensure that the prisoner will cooperate and not head for the hills as soon as their cell door is opened?

You attach a bomb to them.

This is a common means of ensuring that people do things they normally would not do because of common sense. While there are occasions where the bomb is physically implanted, it is usually in the form of a Slave Collar locked around the person's neck. The collar can have a detonator operated by the mission controller. It can be on a timer giving the operator a strict time limit within which to accomplish the mission. Or it can be triggered by proximity to a detonating device placed to prevent their escape.

It isn't always for a government mission that this method of control is used. Explosive collars can keep prisoners from wandering off. They can make friends kill each other. They can make law-abiding people commit crimes.

The collar is always accompanied by a promise to remove it once certain conditions have been met, but there's never a guarantee.

See also Why Am I Ticking?, Boxed Crook, and Your Head Asplode. For non-exploding examples, consider a Restraining Bolt or Slave Collar.

Examples of Explosive Leash include:

Anime and Manga

  • B-Shock: The premise behind the manga. The two main characters have explosive devices attached to their wrists by a Mad Scientist, set to go off if they move too far apart.
  • In The World Only God Knows, Keima gets a collar after inadvertently making a contract with Elsee, a minor demon, to capture wayward spirits. Elsee doesn't go into detail on what would happen if Keima disobeys, apart from an ominous "you'll lose your head". Elsee has a collar as well, and if Keima's goes off, so does hers, so she's got kind of an interest in making sure he follows through.
  • Cyber City Oedo 808 had its main characters and many other cons fitted with explosive collars to ensure they would carry out their missions. In one episode Gogul witnesses how another con tried to take his collar off, and what happened to him...
  • Elfen Lied does it with five-year-old Mariko Kurama. She actually has several explosive implants, located in different parts of her body, and the first time she misbehaves, they blow off one of her limbs as a 'warning shot'. They'll all go off at once if a specific code isn't transmitted every thirty minutes. If this sounds extreme, one must keep in mind that Mariko can kill people with her mind, and has been so damaged by her experiences, she'd probably drive humanity to extinction if she had half a chance.
  • Tengen Toppa Gurren Lagann does it with the Gurren Lagann itself — Simon was scheduled to be executed, but he still had to kick some alien butt before it reached the city, so he asked Rossiu to have his Humongous Mecha packed with explosives. To insure he didn't make a Heroic Sacrifice, they also had Rossiu's companion and Love Interest Kinon ride along in the mech, because Simon definitely wouldn't sacrifice someone else's life.
  • In G Gundam, the space pirate Argo Gulskii was persuaded to become Neo Russia's Gundam Fighter after his crew were captured, so to gain their freedom if he wins the Gundam Fight. He however is a prisoner for life, which means he must wear handcuffs all the time (which have an on-off switch), and has a bomb strapped to his chest. However Just before the final battle against the Devil Gundam, his 'prison warden' Nastasha Zabicov removes the handcuffs and the bomb against orders so he can fight freely. She also frees his friends while she's at it.
  • Mobile Suit Gundam 00's sidestory manga use explosive collars on criminals "drafted" into Celestial Being and its sister organization, Fereshte. While the collared individuals are given more freedom than most examples of this trope, the collar is never intended to be removed, though rare exceptions are made (such as when one got married to a member of the groups... said ex-collared member being Marlene Vlady, the mother of Bridge Bunny Feldt Grace.).
    • Also, anyone who doesn't believe in Celestial Being's Ideology has a leash put on.
    • Fon Spaak, the protagonist of 00F, has his bomb activated during a fight with the Trinities. He survives mostly through sheer determination.
  • In Sora no Otoshimono, when Nymph fails to capture Icarus and awakens her instead, she's given a "second chance" with a time bomb on her collar, more for the Master's entertainment than motivation.
  • In Spiral, Ayumu gets one of these put on him as part of a hostage exchange/battle of wits.
  • In One Piece, the slave traders of Shabondy Archipelago keep their stock in collars that explode if anyone tries to remove them without the proper key. Unless, of course, they can pull it off quick enough like one slave can do.
  • In Gantz, the 'players' have bombs implanted in their brains, which will explode if they leave the area. Most of them are unaware of this fact.
  • In Digimon Savers, Kurata puts one of these on Thomas's beloved little sister, Relena. An 8-years-old or so Ill Girl who is confined to a wheelchair, too! It turns out Thomas' apparent Face Heel Turn was due to his having to obey Kurata long enough to find a way to save her. There's a reason this guy is considered the worst villain in the whole Digimon franchise.
  • In Sonic X, GUN did this to Rouge.

 Topaz: Just think of it as a bracelet.

Rouge: Yeah, a bracelet that explodes.

  • The slave collars in the Magical World of Mahou Sensei Negima. The collars can't be removed by any kind of magic while the slave contract is legal. If someone tries to remove the collar by force, the collar will go boom. The "masters" of the slaves can also use the collars to shock them; one of them does to three slave girls (Negi's friends and students Ako, Akira and Natsumi), but the bear lady watching over the girls beat him up for it.
    • Curiously enough, they also serve as a surveillance device to protect slaves from excessive abuse, as slaves are guaranteed some abridged rights.
  • Hellsing: Millenium actually implants one of these in all of their agents. Granted they don't actually explode, instead they are incinerated. It should be noted that all of the Mooks who are killed this way are vampires they are created artificially so they are vulnerable to this form of termination, while Alucard and Seras are not.
  • Exploding collars are used twice in the Gunsmith Cats manga, by two unrelated villains.
  • When she's made to help Spartoi access the Book of Eibon, Eruka gets one of these in Soul Eater. Harvar is unnervingly matter-of-fact when pointing out she will be killed if she tries anything.
    • Wouldn't be her first experience with such a leash. Early on, Medusa put snakes inside her and Mizune and would kill her in a heartbeat if she disobeyed. Of interesting note is that for a time, she had both this leash and the one above at the same time.
  • 07-Ghost has Teito with an collar that will explode if he doesn't hear Frau's voice for 24 hours.
  • Cyborg 009 uses this with a spin: Shinichi Ibaraki, Mary Onodera and Masaru Oyamada were not only forcibly turned into Cyborgs, but they got bombs implanted in their bodies as a way to keep them under control in their mission. Said mission was to kill their former True Companion Joe Shimamura aka 009; when they cannot bring themselves to do it, the bombs are activated, and the three kids die.
  • A comparatively lite version appears in Deadman Wonderland, where all the prisoners are fitted with poisonous collars. The poison takes three days to kill the prisoners, in which time they have to be able to purchase the antidote candies. So, if they don't get the candies, they die. If they escape, they will have no way to get the candies, and die.
  • In an early arc of JoJo's Bizarre Adventure: Stone Ocean, prisoners (including the heroes) volunteering for a job to find a guard gone missing in the swamp are outfitted with exploding armbands that detonate if they go too far from the guard looking after them.

Comic Books

  • Alien Legion: In the Marvel/Epic series, the members of Force Nomad free themselves from a black hole and are horrified to find that 15 years have passed, they have been declared dead, and all Legionnaires wear control collars. The collars shock any unruly soldier and explode if anyone attempts to remove or tamper with them. They test out solutions on a member who's a blob and therefore pretty unkillable.
  • The modus operandi of the "Task Force X," a.k.a. the Suicide Squad, in The DCU and The DCAU.
  • Variation: at one point, the villain Prometheus (sort of the anti-Batman) keeps The Flash from using his powers with a series of bombs rigged to motion sensors. There actually aren't any bombs, but Flash doesn't know that.
  • The Power Limiter of Albert Cranston in PS238 includes one of these.
  • Skywatch puts one of these on Shockwave to force him to clean up their mess in IDW's Maximum Dinobots miniseries. He does not sound particularly fazed by the threat of a 24-hour time limit before it will fry his CPU.

  Shockwave: Do you have any conception of how much damage I could do to this insubstantial world in that time?

  • In a special comic where Batman and Superman are meeting for the first time, Batman keeps Superman from arresting him by claiming that special sensors in his suit will trigger a bomb that will kill an innocent somewhere in Gotham if Superman tries anything. Superman verifies that he's telling the truth by checking his heart rate and other vitals and is forced to work the case with him. Seem out of character for Batman? Not when the 'innocent' in question is him; he's wearing the bomb, knowing Superman would be able to sense a lie.
  • Gold Key published several issues of a comic book based on the tv series The Man from U.N.C.L.E.. In one issue, "The Pixilated Puzzle Affair", Napoleon Solo and Ilya Kuryakin were held captive on an island prison colony where all the prisoners had explosive pedometer-like devices attached to their ankles. Each prisoner was permitted a specific number of strides per day; if any prisoner tried to walk or run beyond the permitted distance, his device exploded.
  • Captain Atom: Plastique puts one on Cameron Scott to prevent him from transforming into Captain Atom.
  • Planetary: In one issue, the Planetary field team raid one of the Big Bad's facilities, where a group of child prodigies in explosive collars are being forced to subvert the internet.

  • Saw III featured an explosive collar made with shotgun shells placed around a doctor's neck set to explode if Jigsaw (who is bedridden with terminal cancer) dies, thereby forcing her to keep him alive. It goes off when her husband, not knowing about this trigger, slashes Jigsaw's throat as revenge for all he put them through. It's also possible she was screwed either way, since the collar was made by Amanda, whose traps were all inescapable and the key Amanda carried didn't fit the lock of the collar.

  • Used in Escape from New York to motivate Snake into performing his mission. However, this version of two tiny explosives implanted in the neck that are just large enough to fatally open his arteries when they explode, which would happen with their coatings dissolve in about 24 hour.

  • Battle Royale and its various adaptations and sequels.
  • Neal Stephenson's The Diamond Age has devices called Cookies Cutters: cell-sized explosives capable of taking a small chunk out of a person, and usually injected into them in quantity. They can be detonated after a period of time (known as the Seven Minute Special), by remote control, or by passing a radio barrier. Used for execution and prisoner restraint (in large quantities) or for pacifying criminals (usually one is enough).
  • In the Starchild Trilogy, political dissidents are fitted with explosive collars with undefined timers that need to be periodically "wound up" by the guard's key to renew the timer. Within the series, legend has it that the only way around the tamper mechanism is to detach the head, remove the collar, and sew the head back on.
  • In the Chung Kuo series by David Wingrove the government of city Europe 'wires' people with small explosives to ensure order.

  • The Shapeshifter uses this, combined with a Restraining Bolt in the form of a chip inserted into the COLA's skulls.
  • Storm Thief, when Grimjack decides to recruit a somewhat tricky beggar boy to his cause, and uses a "persuader". To quote: "You try to take it off, it'll blow your arm off. You don't do what you're told, I twist this thing, three beeps, and it blows your arm off. If your not back at the Null Spire within three days, It'll blow your arm off." and so forth.later he is caught by his own explosive leash, when the boy is able to remove it, and pickpockets Grimjack to substitute the device for the detonator. Then of course he gives it a twist, which confuses Grimjack, who only realised his mistake three beeps later...
  • In The Court of the Air the feybreed are forced to wear suicide torcs as part of joining the special guard.
  • Able Team. When Carl Lyons is captured by the Unomundo organisation he pretends to do a Face Heel Turn, planning to escape when he has a suitable opportunity. Later when sneaking around their headquarters he breaks into a room which has X-Rays taken of his neck, showing an implant the size of a AAA battery, in the same position as a surgical scar which Carl assumed was a result of his injuries when captured. There are also a series of photographs of a South American peasant with a similar scar, before and after his neck is blown open. Later when the rest of Able Team arrive to rescue Carl, they have to cut out the device with a shard of mirror glass (in case the bomb is magnetically triggered).
  • In Bitter Gold Hearts, Garrett slips an enchanted crystal into Skredli's pocket and tells him that if he doesn't follow through on the plan they'd agreed to, it'll explode and tear the unfortunate ogre in half. Possibly a subversion, as the witch he'd gotten the crystals from didn't seem the sort to craft an Explosive Leash, so Garrett may have been bluffing.
  • In Larry Niven's short "Neutron Star," UN Agent Sigmund Ausfaller did this to Beowulf Shaeffer's ship. Well, it wasn't actually Shaeffer's; it was the Puppeteers'. Ausfaller (correctly) suspected that Bey would take the ship to Wunderland and sell it instead of fulfilling the mission the Puppeteers contracted him for, which was figuring out how some explorers doing a close orbit of a neutron star got themselves killed through and (ostensibly invulnerable) General Products hull. Answer: tides.
  • Tortall Universe: in Trickster's Choice, when Aly is made a slave, she is forced to wear a collar that will strangle her if she tries to escape. Until she convinces her new owners to disable it.
    • Although it was closer to "give them an excuse" to disable it than "convince them", as she actually had to convince them — more than once, IIRC — to keep her a slave.
  • An unusual self-inflicted example appears in the Sten series. Long ago, the Eternal Emperor implanted himself with a Judgement Device that would constantly monitor his thoughts and explode if he was ever brainwashed or went insane. Of course, being Immortal, he did so with the expectation that he'd get better afterwards.

  • In the Doctor Who episode "Boom Town," a prisoner is kept close to the Doctor with the help of explosive handcuffs. No one should be surprised that he got them from Jack Harkness.

  • Flashpoint
    • "Eagle Two"; the person under this codename that SRU Group One is protecting has one of these put on her, the people who did it claiming that if her husband publicly confesses to a crime he committed in the terrorists' home country years ago, it will be removed. If not...
    • A more twisted version is used in the earlier episode "Planets Aligned," where a man who has kidnapped two girls puts an shock collar (the kind meant for training dogs) on their leg, telling them that if she get too close to a door or window it will buzz, and if they leave the house an underground wire will administer a lethal shock. It's not made clear if he's telling the truth about the "lethal" part, but the SRU do find the wire.
  • MacGyver: In the first episode of 's third season, the Russians place an explosive leash around the neck of MacGyver's ex-girlfriend of the week, to coerce him to steal one of China's national treasures.

  • In the Criminal Minds episode "Won't Get Fooled Again", where a man walks up to the FBI with a bomb strapped round his neck.
  • Used in the Law & Order: Criminal Intent episode "Pas de Deux" (which was probably inspired by the Brian Wells case described below).

  • Crusade: Max Eilseron uses one of these on a Loan Shark, a rather literal case of Applied Phlebotinum, since the collar is fired from a gun and seems to form itself around the victim's neck at high velocity, forming into a seamless tamper-proof explosive collar. He does this to get the guy to stay away from Max's ex-wife. Not because he was particularly fond of her, but because the guy was holding their cat hostage. The safe return of the cat was also part of the deal.
  • A flashback in Kaizoku Sentai Gokaiger shows that Joe was fitted with one when he decided to rebel against Zangyack. After Captain Marvelous rescues him from a hit squad, he removes the collar by sheer brute force and ballsiness, which makes them inseparable True Companions.

In reality the bomb is for real, but there's no boss: the guy made the bomb itself and lied about others putting it on him, hoping for an alibi. Karma bites him in the ass when one of the tellers escapes and tries to unlock her car... but the key's electrical signal accidentally triggers the bomb and makes him go KABOOM

Bob instantly agrees to wear the "leash." Later on it is revealed that the explosives were all a lie, and Bob wouldn't have been hurt by a bomb anyway. Bob was not amused, and only didn't kill Wily because he claimed he found the way to get him back home.
  • In Girl Genius, sent to the Castle Heterodyne inmates are "given" explosive collars, just in case the castle wasn't dangerous enough in and of itself. Also, there was a clause that prisoners will have amnesty if a Heterodyne is ever reinstated in the Castle. Klaus keeps his promises, so it turned out that even without his representative, collars immediately react on the traditional signal for this event — which was not easy to forge, to say the least — by falling off.

  • Antimony in Gunnerkrigg Court got to wear a lite version. After being too talkative on a dangerous topic in the wrong time she had her wrist wrapped in the bracelet supposed to snip her hand off if she divulged Coyote's secret to anyone during the vacation on his territory. It's obviously a part of object lesson, though he may or may not truly care about a disclosure as well. But at least it looks stylish. It turned out that she's not the first to wear such an accessory. Once conditions of the limitation are not appliable (out of forest), she was able to remove the binding herself — it simply vanished in thin air. Also, going by her memories, for ether sight it looked like a pinwheel of teeth.

 "Could I at least tell my wife?"


"The Bomb says no, Brian."

Web Original

  • The game Survival of the Fittest, in keeping with Battle Royale, the series that inspired it, has each of the "contestants" on the island fitted with an explosive collar that goes off if they try to leave the island or go into a danger zone. It also explodes if they try to remove the collar, making removal almost impossible. Damaging the collar enough, particularly by gunshot, is also enough to detonate them; two students died this way in v1.
  • Tod in Interviewing Leather get one of these around his neck.
  • SCP-076 from SCP Foundation wears one of these. It's been activated several times, as its purpose is simply to incapacitate him long enough to get him back.

  • Justice League Unlimited made a particularly nasty variant of this by lacing a death row prisoner's last meal with nanites before recruiting him into the Suicide Squad Task Force X in the episode of the same name. The nanites can be programmed to detonate his internal organs if he disobeys.
