EMP, short for electromagnetic pulse, is often used in stories to take out anything electronic. Sometimes shown to be a temporary effect (especially when the Rule of Fun
applies in games), it usually results in the permanent disabling of electronic systems.
Now for a more detailed explanation
When a nuclear warhead explodes, it releases a LOT of gamma rays, which are photons with tons of energy. When these photons travel through air, they strip electrons off the air molecules as they zoom past. This is called "ionizing" the air. Because those photons are so very energetic, they do it over a very long distance and make a huge volume of ionized air.
Ionized air becomes a conductor. This means those stripped-off electrons, energized by the gamma rays, are free to move around in an electric current. Any change in current produces radio waves. And since the current is going from zero to huge in a very short amount of time, this means a large portion of the atmosphere becomes a HUGE radio transmitter, broadcasting noise at full power.
Radio waves have the generally useful property that they induce currents in conductive material (that's how a receiving antenna works). So whenever these INTENSE radio waves hit something metal, like the wires inside your computer, they produce proportionally INTENSE power surges. Ever had a piece of electronics destroyed when lightning hit your house? This is a similar effect, except bigger. And everywhere. At the same time.
As a bonus, the main pulse is followed almost instantly by secondary ones. The original nuke releases neutrons, which run into things and produce more gamma rays, which produce another wave of electrons. And after that, the Earth's magnetic field "heaves" a little when hit by all this stuff, and that magnetic effect can zap anything connected to really long wires.
Doesn't that sound like fun?
In particular, silicon transistors — the building block of modern electronics — are very sensitive to these power surges. The induced current burns and destroys them. They are so sensitive, in fact, it has been theorized that a single nuke, detonated in the right part of the upper atmosphere, could take out most of the unprotected computers in the United States. Also, it is theorized that a high-intensity EMP burst could destroy silicon transistor circuitry even if the device is turned off. Military hardware has to be specially shielded to withstand most of the effects. Interestingly, ancient computers from the 1950s would also be resistant; they were built with vacuum tubes, which can take the pulse a lot better than modern transistors, especially if they were powered down at the time. Also, it's possible that early transistors, which were made of germanium rather than silicon, might be able to withstand an EM pulse if the device was powered down.
If you want to do this zapping without the nuclear fallout, there are a few smaller weapons
that can generate an EMP. Such a thing is usually a kind of single-use electric generator, which sends out its pulse when crushed by a conventional explosive. The pulse is far weaker, and can kill maybe an office full of computers. In case you wonder why the same explosive charge alone couldn't do it, a range can be extended by rigging up a generator to get a directional emission of microwaves instead of a plain magnetic surge. Getting a city-sized EMP without a nuclear bomb is not feasible with current technology; as to reusable variants, if we had the capacitors necessary to do that, we could also build practical railguns
and laser rifles.
Weapons aren't even needed to create an EMP, though: a sufficiently sized solar flare or other cosmic ray event can do it - a pre-nuclear example exists in the Solar Storm of 1859, known as the Carrington Event
, A gamma ray burst or supernova far enough away to not fry the Earth with enough ionizing radiation to actually pose a threat to human life itself could also accomplish creating a global disaster from an EMP.
A more docile variant of EMP is "degaussing," which uses a varying magnetic field to remove magnetism from a metal object. Ships in WWII were degaussed to make them less vulnerable to magnetic mines. The last generation of CRT monitors, which were what most desktop computers used before LCD/LED displays took over, had built-in degaussers to eliminate color aberrations caused by stray fields. And bulk erasers, an even smaller and lower powered version of this, is used to destroy the data on magnetic storage devices (very popular with the BOFH
When Hollywood talks about EMP, it can generally be filed under Artistic License - Physics

Anime & Manga
- Highschool of the Dead features one moderately realistic EMP generated by a low-altitude nuke exploding over Japan.
- In Mobile Suit Gundam SEED, ZAFT has the Gungnir System, which it deploys when they attack Panama — and then proceed to slaughter Alliance soldiers trapped in disabled mecha. Even the revenge-minded Yzak gives pause at this, hinting at his later Heel-Face Turn.
- The Minovsky Particle in the Universal Century timeline is also mentioned as capable of emitting EMP. Not only did this render long-range radar useless and made it necessary to shield electronics in bulky armor, but it also made the very idea of mobile suit combat possible.
- In The Animatrix, "The Second Renaissance", it is said that the machines had little to fear from nuclear explosions as they were not affected by the heat and fallout, completely forgetting about the effects described in the page's intro. Which is weird because the movies play it straight.
- Villain (and occasional ally) Magneto does this from time to time. Considering how flexible his magnetic powers are usually depicted as being, it's not completely out of the question.
- Storm has done it with lightning bolts which... isn't possible.
- In the second issue of Global Frequency, one of the characters carries non-lethal weaponry, such as EMP grenades, when they are going against a full-body enhancile. They are... not exactly non-lethal.
- In Batman: The Dark Knight Returns, the Soviets launch a single nuclear missile at the contested island of Corto Maltese. Superman knocks it off course, but, as Batman points out, this is not a Nuke 'em weapon — the "Coldbringer" is designed to knock out the enemies' ability to fight, without damaging infrastructure. The weapon detonates, Superman gets almost dead, and the electrics fizzle out in most of the Americas.
- In All Fall Down, the Colony Drop-sized asteroid Penumbra seems to be radiating this, making any missile attack impossible.
- Iron Man has one built into his armor. It disables his own gear as well, which then takes about six minutes to fix itself. The exact same thing is in the War Machine armor.
- In Aeon Natum Engel, among the standard depictions of EMP, it's also one of the main reason for the Iceland's Decade Dissonance.
- Before their invasion of Earth in Worldwar: War of Equals, The Race drops several EM Ps on the atmosphere to knock out communications and confuse military forces. Only the US, Mexico, Germany, and Egypt are spared since their air force fighters cut them off just in time.
- Between Minds (HalfLife X Portal) uses one to nuke a couple Advisors' life support during an aerial battle!
Films — Animation
- In Cars 2, Allinol is actually a deadly chemical invented by Miles Axlerod that was designed to catch fire and explode inside a car's engine after being blasted by a deadly electromagnetic cannon built by his Dragon, Professor Z that resembles a video camera.
Films — Live-Action
- The last-resort weapons against the robots in The Matrix trilogy. Big problem there is that they disable your own devices as well. That includes the devices that plug people into the Matrix.
- In the 2005 film The War of the Worlds the aliens subject urban areas to a terrifying EMP weapon disguised as a lightning storm. It is designed to wreck our technological society before the tripod assault: a instrument of total war. It works, but cars at least are easily fixable.
- In Air Force One a stewardess mentions the eponymous plane is protected against this, which we can suppose is Truth in Television.
- In John Woo's Broken Arrow, a nuke detonated underground produces enough EMP to knock down a helicopter flying above it.
- This is the favorite weapon of Blackout in the live-action Transformers film, and other Transformers have used such weapons, if only mentioned in their Tech Specs.
- In Small Soldiers, the kid blows up a power transformer in the back yard. This generates an EMP that fries the circuitry of all the evil toys. The good toys are shielded by a downed satellite dish, somehow.
- In the remake of Oceans Eleven, Don Cheadle uses an EMP generator to cause a power outage at the casino so George Clooney and Matt Damon's characters can get past the security lasers. He even describes the device as "a nuke... without the nuke." Assuming that such a device could be built, the rapid restoration of power is a Artistic License - Physics/Artistic License - Engineering double-header. Not to mention the additional effects that would certainly kill people given the loss of power would also affect anything with an engine and anyone on any kind of life support (e.g. pacemakers).
- In The Return Of Godzilla a mild EMP effect was the side effect of prematurely detonating a nuclear weapon launched to kill Godzilla.
- The nuclear bomb in the Made-for-TV Movie Medusa's Child.
- James Bond
- The eponymous Kill Sat in the movie GoldenEye.
- And the MacGuffin (though only for the first half of the movie) in A View to a Kill is a computer chip that can withstand EMP, built by Zorn Industries — Bond is investigating how one of these chips ended up in the Soviet Union.
- The "Ion Cannon" in The Empire Strikes Back is a cannon that disabled an entire Star Destroyer without destroying it. "Ion" weapons in future installments of the Expanded Universe (particularly video games) specialize in disrupting machinery. But without permanently shredding the electronics as EMPs do. It's implied in one of the stories (IG-88's section in Tales of the Bounty Hunters) that it does permanently destroy circuity and such, but there are usually ways to auto-repair the damaged paths. Hence the temporary shutdown period, between "destroyed" and "repaired enough to function".
- Shows up in Escape from L.A. as part of a top-secret government project that ends up being stolen by a terrorist who threatens to zap America if the government doesn't meet his demands. The film ends with Snake zapping the entire world instead.
- The BBC's nuclear holocaust drama Threads: The Soviets detonate an airburst above Britain to knock out communications and computers with EMP before nuking the rest of the country.
- Also in the US Made-for-TV Movie nuclear holocaust drama The Day After.
- Pacific Rim has one of the Kaiju knocking Hong Kong off the power grid, along with disabling a jaeger, with a burst of this. Yes, a Kaiju.
- During the final battle in Serenity a Reaver ship knocks out Serenity's electrics with an EMP beam weapon, sending her into a flat spin. Wash manages to get partial power back and pulls off a relatively controlled crash-landing.
- Outpost Black Sun. The special forces team has a backpack version which is the only effective way of stopping the Nazi zombies. The problem is it's one-shot only and they use it straight away.
- In Godzilla (2014), the MUTOs have the ability to emit natural electromagnetic pulses. Indeed, the lights suddenly going out in the area serves as an indirect sign that they are nearby. It also makes it difficult to use many modern weapons against them, as evidenced by the scene where a bunch of fighter jets sent to take one out suddenly shut down and crash into San Francisco Bay.note Of note, at first it seems the use this accidentally (as it seems more them trying to use the shockwave that accompanies them setting it off), but by the time of the San Francisco, the male Muto has seemed to learn to use it offensively.
- In Harry Turtledove's Worldwar series, the Race begins their assault on Earth by using EMP to disrupt human technology. However, as this is set during World War II, most of humanity's electronics consist of vacuum tubes and are thus unaffected, to the surprise of the invaders.
- William Gibson's Neuromancer:
- The US military flight unit "Operation Screaming Fist", led by Colonel Willis Corto (Armitage), is taken down by Russian EMP weapons.
- In the Neuromancer universe, many companies use Artificial Intelligences to run their computing needs, especially security. Notably, there is a regulatory agency (the Turings) that is aware that AI Is A Crap Shoot: as such, all AI-equipped supercomputers must be built with an EMP destruct device, triggerable by any Turing agent. As one AI-savvy character puts it, "Every AI ever built has an electromagnetic shotgun wired to its forehead." This is important, as the story revolves around two AIs (Wintermute and Neuromancer) that wish to merge into one superentity-an act that would certainly trigger the EMP bombs.
- EMP (especially handheld EMP) play a key part of Orson Scott Card's Empire series.
- In All Frequency Jamming/Full Band Interception by Chinese Sci-Fi writer Cixin Liu, the future Russian (or Chinese, as it's changed in the Taiwanese version) army saved themselves from the conquer of NATO by using EMP in the most badass way — first by deploying stationary EMP emitters, then by ramming a giant space station into the sun!
- Carrera's Legions: EMP bombs using conventional explosives to create the pulse are deployed by the Legion several times throughout the series to knock out enemy electronics, particularly their communications.
- In Moon Over Soho the cover story for the Masquerade is that a suspect premises had a miniature EMP bomb in it and not a magical demon trap.
- In Max Barry's Machine Man, love interest Lola's Heart Trauma is mended with a model that discharges an EMP when she gets excited. It does considerable damage and ends up as a Chekhov's Gun.
- In William R. Fortschen's One Second After, an EMP is generated when several nukes are detonated in the atmosphere over the US.
- A key element of the plot of Charles Sheffield's novel Aftermath.
- As mentioned above, the Bastard Operator from Hell has on occasion used a bulk eraser to destroy incriminating evidence or a user's files. He and the PFY also built a portable version which they used to destroy vending machines and ATMs in a revenge spree, until on the way back they accidentally set it off inside the elevator...
- In The Leonard Regime, it is mentioned that the west coast of the United States had been hit by an EMP attack during a previous war. It is functional by the time the story takes place.
- The War Against the Chtorr. A robot is sent into an alien dome to flash it with EMP, hopefully killing any man-eating alien worms before The Squad follows. A footnote helpfully informs us that an EMP-grenade will cook or curdle any living matter within a radius of (CLASSIFIED). A single charge will yield as many as (CLASSIFIED) useable pulses. There is also the tendency of the flash to destroy any unshielded electronic gear within the larger radius of (CLASSIFIED). One could argue this is a good writer's technique to explain what EMP is while Black Boxing the actual technology involved.
- Stargate Verse
- Doctor Who
- An EMP is used to disable the robot angels in the episode "Voyage of the Damned".
- Also, earlier in the series, a small, hand-grenade-sized EMP device is used to knock out a single Cyberman in "Age of Steel". It succeeds in frying its emotional inhibitor chip and to disable its motor functions, but for some reason, the thing can still operate its speaking device and the Doctor has to power down the energy core manually. One also has to wonder, shouldn't the plate armour, which the Cybermen are encased in, work as a faraday's cage?
- In the first season of Heroes, HRG got Nuclear Ted to emit an EMP instead of his normal nukes in order to shut out the power at Primatech so they could escape.
- In Dark Angel the United States is a third world country because of a terrorist EMP attack.
- In Day 4, a defense contractor deploys an EMP taking out several square blocks of downtown Los Angeles.
- During Day 8, Samir's terrorists sneak an EMP bomb into CTU New York with an "escaped" hostage to disable the Manhattan radiation sensors.
- Leverage features both a handheld version and the much larger bomb version. The handheld version is a much smaller version of the kind that is in development for use in police pursuits. The bomb version actually averts the mistake of Ocean's Eleven, Hardison explains that setting off the device would make them the largest terrorists in American history.
- In the Bugs episode "Pulse", the EMP is referred to as a "pulse bomb", which the protagonists use to escape a heavily armed villain.
- In an episode of Terra Nova a meteor with a high iron content was somehow able to generate an EMP capable of frying every microchip in the colony, including the ones for the chip fabricator. While waiting for a new fabricator chip to be hand-etched, they had to fend off a Spinosaurus attack with compound bows.
- In the Smallville episode "Metallo", Clark Kent uses a device to trigger one in an attempt to disable Metallo. Unfortunately, Metallo restarts after a few seconds.
- In the Intelligence episode "Athens" an EMP attack disrupts Gabriel's chip, giving him Laser-Guided Amnesia. In the epilogue Dr. Cassidy modifies the chip to make it less susceptible.
- Paranoia has the Gauss Gun, a directional EMP weapon useful against robots and other electronic equipment.
- Warhammer 40,000 has EMP grenades as Tau equipment used for dealing with tanks. They rarely see that much use, due to the Tau being the inventors of the railgun — a long-ranged tank killer that makes a lascannon look wimpy.
- GURPS: Ultra-Tech has EMP warheads for properly sized projectiles. Microwave disruptors use a similar technology but are somewhat less effective. Oddly they don't fry the system, instead the effect leaves computers temporarily "unconscious".
- City of Heroes has a couple of EMP powers, one of which is delivered via Trick Arrow. It's just described as "a massive pulse of electromagnetic energy", without going into detail how it is formed. They are "powerful enough to affect synaptic brain patterns" (i.e. temporarily disable all enemy actions, electronic or otherwise), while dealing "high damage to machines and robots". It's a very good power, it just doesn't make much sense outside of Superhero Logic.
- Solidus attempted to EMP New York City in Metal Gear Solid 2: Sons of Liberty.
- Quite a few video games have EMP grenades as weapons. Examples:
- The Fallout series. Fallout 3 includes Pulse Mines as well. Fallout: New Vegas also adds a "Pulse Gun," an energy weapon implied to be an electromagnetic pulse gun, as it has the same damage bonus vs robots and Powered Armor as EMP grenades, along with Pulse Shotgun Slugs. The nuclear war-induced EMP's may also be the reason the only working pre-war electronics run on vacuum tubes.
- Enemy Territory Quake Wars. Considering that your enemy are basically Borg, this works quite well.
- In Quake IV, your team attempts to use one to break the connection with the Strogg's Hive Mind, but the bomb gets destroyed by a Harvester en route.
- Battlefield 2142
- Halo 3
- Deus Ex features EMP grenades, which are effective against enemy bots. In a twist the protagonist is a cyborg: it's not healthy to get caught in the EMP radius of your own grenades.
- Deus Ex: Human Revolution has them as well, but an upgrade to your augmentations can render you completely immune to their effects. They're also good as distractions against purely human enemies, as they will investigate an EMP explosion as if it were a regular explosion. Important for a Pacifist Run.
- Project Snowblind naturally includes them and forms the main plot line.
- In Everything or Nothing, EMP grenades are a part of James Bond's arsenal.
- Certain rockets have this as an effect in Armored Core: They temporarily stun the enemy mech.
- EMP grenades in Transformers: War for Cybertron scramble the HUD and cause static to appear on screen, while leaving movement and weapons operational. They're used by the Scout class.
- Star Wars: Republic Commando has EMP grenades that are extremely useful when you run into hordes of Battle Droids, especially Super Battle Droids. Notably, they are also effective against organic enemies as they emit an electrical discharge as well - being shocked by several thousand volts is not a pleasant experience whether you are made of metal or flesh.
- Plants vs. Zombies 2 has the E.M.Peach, which disables all robotic zombies in an area. Considering that many robotic zombies are extremely durable, this can be very useful depending on situation.
- In Banjo-Tooie, Mumbo can use an EMP spell in Grunty Industries to shut down factory machinery.
- StarCraft features an EMP-wielding giant spaceship. The EMP knocks out shields, making it only useful against one race, but only REALLY useful against Archons, who have 300 shield and only 10 life. The EMP also eliminates the energy of any units that use energy for abilities, so it can be quite helpful against Terran armies as well. It even works on zerg casters, even though their "energy" is their internal supply of symbiotes and biotoxins. But at least it's consistent.
- StarCraft II features the ability on the Ghost. But on a lower scale, only stripping a certain amount of energy off units.
- Crysis Warhead features EMP grenades that are used to disable the enemy's nanosuits, making them easy kills.
- Crysis 2 lacks EMP grenades, but it does have the K-Volt sub-machine gun, which fires electrostatic bolts that knock CELL troops off their feet and "stunlock" Ceph enemies in place. The Ceph themselves have an EMP emitter seemingly built into their exosuits which instantly drains your suit energy, disabling your powered armor, cloaking, and sprinting functions, and they will make very good use of it when searching an area for you. Grunts and Stalkers have short-ranged EM Ps that have a range of about a meter or two, while Pingers have a much larger one combined with some form of sonic pulse, leaving you at the mercy of its rapid-fire plasma cannon should you be caught in range.
- The Team Fortress Classic Engineer has EMP grenades, which detonate all of a foe's held shells and explosives. This makes it incredibly deadly against heavier targets such as Soldier and Heavy, but less effective against lighter classes like Scout and Sniper.
- System Shock
- The Magpulser is available. It looks strange, but yes, it harms robots a lot (200% damage). It also lives up to its name by barely affecting cyborgs (50% damage) and not affecting mutants at all (0% damage).
- There are also a couple of other EMP weapons, specifically the EMP grenade, which, when detonated, can screw up your (computer-assisted) interface if you're too close to the blast. It also drains your battery for some reason. There's a more powerful land mine version as well.
- Sequel System Shock 2 has the EMP rifle while the EMP grenades make a return, which absolutely devastate robotic and cybernetic enemies (the cyborgs have all their life-support systems in their mechanical parts, meaning that damaging them will kill them), but are absolutely worthless against a purely biological enemy. Since some of the most powerful enemies in the game are biological, it limits the effectiveness of the weapons at specific sections of the game. The rifle, as well as the EMP grenades, however, will come in very handy during the Final Boss fight.
- The Dark Forces Saga feature an EMP-shooting gun which is mostly for killing robots.
- Command & Conquer
- In Command & Conquer: Generals, the Superweapon General's base-defense missiles and one of the special powers of high-ranking Chinese generals are EMP-based. These disable vehicles and buildings (albeit, temporarily). When said EMP base-defense missiles hit aircraft, however...
- Command & Conquer: Tiberian Sun
- Features an EMP cannon on both factions, while its expansion had a mobile EMP tank for GDI. Its more useful against GDI than Nod due to Nod's tendency to use fragile speedsters and that the cannon takes some time to charge and shoot.
- In Generals, China has an EMP bomb dropped by an airplane. Pretty effective if used with other special abilities to destroy an enemy force or as a starter for an attack on the enemy base. And it looked cool.
- Tiberium Wars has a tech building that can be captured to grant an EMP attack that temporarily disables enemy buildings.
- FreeSpace 2 has a mission that takes place in an area of a nebula with EMPs happening all the time, and a missile that causes one when it explodes. In either case, this causes a massive Interface Screw.
- In Modern Warfare 2, a nuclear missile is detonated in the upper atmosphere over America, blacking out the eastern states and causing the player to dodge helicopter rain. The player also gets an EMP in multiplayer if they get a Kill Streak of 15, which disables enemy electronics, including removing their radar, ammo count and the game score. It still fails physics forever, of course, because the team that used it is unaffected and the effect only lasts for about two minutes. Modern Warfare 3's Multiplayer introduces EMP grenades that become available at Level 21. The EMP is applied only to players and their electronics caught in the blast radius and the effect lasts for a much shorter period of time. Acceptable Breaks from Reality — who would use the EMP if it affected their own team as well? Nobody. Who would use the EMP if it lasted until the end of the round? Everybody.
- The Space Pirates occasionally use EMP grenades.
- Steam Lords of Elysia can also generate one as an attack.
- Presumably, Samus' suit is well-protected as neither of these actually does anything to her suit beyond standard shield drain. Some special electricity-based attacks, however, cause static to appear on the HUD.
- Getting hit by an EMP in Metroid Prime: Corruption instantly puts Samus into corrupted mode with a full phazon tank. This is a double-edged sword for the pirates though; if Samus can't vent the phazon in time (due to a paralyzing attack, for example) it's a Non-Standard Game Over for her, but to vent phazon she has to Beam Spam it all out, and those beams are highly destructive to anyone nearby. (Such as, for example, the hapless pirate that threw the EMP...)
- In Ratchet: Deadlocked, your Battle Bots have EMP grenades equipped that allow the temporary deactivation of Stalker Turrets and other electronic obstacles.
- Splinter Cell
- Splinter Cell: Conviction has a plot focused on detonating several EMP bombs in Washington, DC. Sam actually gets a backpack that has a built-in EMP generator fairly early in the game. It can only be used three times per level (no recharging it like other gadgets) and the effect is purely temporary, lasting ten seconds at most. He also has access to EMP grenades, which are even less effective, but ranged.
- Splinter Cell: Chaos Theory before added an attachment to the pistol called the "OCP", which allowed the player to temporarily disable any electronic device they aimed the pistol at. This was of the "microwave" variety of electronic disruption, and thus was more directed than many examples.
- In Devil Survivor, it is explained that the PSE law places a chip in all electronics so that they can do this to all of Tokyo in a massive explosion. In fact, that's their if-all-else-fails plan.
- In Need for Speed: Hot Pursuit 2k10, both the police and the racers use EMP devices on each other. In the "Porsche Patrol" cop event, you gain an achievement/trophy by using the EMP weapon to take out the computer-controlled gas/electric 918 Spyder Hybrid concept.
- In Battlefield: Bad Company 2 the plot revolves around the members of the Bad Company trying to find a mysterious weapon which turns out to be an EMP.
- Bubble Tanks Tower Defense 1.5 introduces the EMP creep, which explodes into an electromagnetic pulse upon defeat. This disables all the towers around it, and as such makes it an annoying foe to fight.
- Perfect Dark has EMP mines which have to be placed on the computer terminals to disable the security system in the first level. Unfortunately, they don't appear in other levels with security cameras.
- EMP grenades are a recurring weapon in Metal Arms: Glitch in the System. It temporarily deactivates every machine in the vicinity, although there's no real effect to the player except for disorienting and confusing your control scheme.
- Freelancer features a series of EMP-generating missiles (the Eraser line), as well as "pulse cannon" guns. However, in practice all they do is strip away a target's Deflector Shield.
- Transformers: War for Cybertron and its sequel ''Transformers: Fall of Cybertron both have EMP Grenades that warp the optics of whoever they hit, as well as doing a fair bit of damage.
- The use of one forms the climax of the Red vs. Blue series "Reconstruction". The characters also spend a lot of time arguing over whether it's pronounced "E-M-P" or "emp", with even the computer warning using the latter pronunciation, making Washington the only one who uses current pronunciation of E.M.P.
- MegaTokyo Largo uses one as a rickroll.
- Aylee from Sluggy Freelance has her Involuntary Shapeshifting mutate her into a living EMP generator in response to a nanite infection. It caused problems as she had to routinely run away from the house for fear of accidentally setting off one of Riff's inventions. Or worse, erasing Bun-Bun's Baywatch video tapes!
- An EMP effect was used by the protagonists of Molten Blade to aid their escape from a research facility, generated from a device referred to as an "e-bomb" by one of the characters.
- In the Boband George comics, during the Mega Man 3 storyline, Mega Man was able to convert the Magnet Missiles into an EMP. It's very effective, but he burns them out after two uses.
- The author actually goes into an explanation about how EM Ps work, and why it didn't work against Snake Man.
- Girl Genius
- In Freefall Ecosystems Unlimited uses an EMP generator to erase digital information from used robot parts. It has no effect on post-it notes, though.
- Annie's choice of superhero name (and the strip title) of Pulse is based on this because of her electrical powers.
- Quentyn from Tales of the Questor once built a magical version (involving a keg of salt and copper tubing left under the Luxfont for a few days) in order to neutralize a street gang's magical weaponry.
- In S.S.D.D Tin-Head's set-up at Cook Industries has an EMP bomb in case of emergencies. His own neural net is shielded so it wouldn't harm him but everything else in the room is fried when he triggers it after accidentally contacting the Oracle, and just to make sure he erases his most recent memory.
- Another time a CAS elite uses an EMP grenade to disable a killer robot, then his partner asks how they're going to get out now that the pulse has trashed all their gear.
- Max Steel has an episode where Roberto builds a handheld, explosion-less EMP projector in a very short timeframe as a method of dealing with super robots gone rogue. This causes a friendly-fire issue, as Max will die if he loses his nanoprobes. which are just as vulnerable to EMP, and the robots immediately start a fight instead of helpfully lining up. One of them even goes for the EMP device when Berto hesitates on account of this, presumably intending to aim it at Max. Max solves the problem by taking it and using it himself, thus putting his body behind the direction of the blast. He still takes enough of the EMP to destroy a large portion of his nanoprobes, and loses consciousness while the survivors cannibalize the dead probes to replicate new ones.
- Transformers Animated: Ratchet has a wrist-mounted "EMP generator" that can focus an electromagnetic pulse into a beam. It can temporarily knock out most Cybertronians, but Ratchet prefers to use it as a surgical tool, and then only rarely. At full power, it can wipe an Autobot's entire memory, which accidentally happened to Arcee during the Great War, hence his reluctance to use it. He and Bumblebee can temporarily knock a flying Decepticon out of the air by combining their normal weapons (electric stingers + magnets).
- Team Chaar's Blackout, like the movie 'bot who inspired him, can create an electromagnetic shockwave that knocks out nearby machinery... and then bring them back online by doing it again.
- Blaster uses an EMP gun. It blows up normal electronics but Transformers, being more resilient, only suffer from seriously impaired movement coordination (still very painful if you happen to be in jet form at the time).
- The Teenage Mutant Ninja Turtles (2003) episode "Modern Love" has the turtles whip up an EMP to disable a rampaging Nano.
- The Monster Buster Club episode "Pipe Dreams" has Mr. Smith using an EMP (though not called as such exactly, as it's alien technology) to disable the machines of the Invader of the Week before he'd unearth the MBC tunnels and absorb a good part of the town with his Tractor Beam. Unfortunately, it disables the kids' weapons and other gizmos as well, so they have to take out the menace hand-to-hand.
- In The Simpsons, Homer joins a group of "preppers", who believe an EMP would cause the end of civilization, and they would be the only ones ready. When an EMP does occur (thanks to Homer's incompetence, of course), the preppers bug out and hide out in their compound, awaiting the apocalypse. Eventually the Simpsons return to Springfield with the intent of helping them, but find everything back to normal. Seems the effects of the surge were only temporary, and with all the crazy people (meaning the preppers) gone, order was restored with surprising ease.
