Nuclear Nasty

"Touch a button. Things happen. A scientist becomes a beast."

A sub-trope of I Love Nuclear Power, Nuclear Nasty is a monster (usually the Monster of the Week) created when a creature is exposed to radiation. Very common in 1950s monster movies, as well as works trying to be throwbacks to that era for obvious reasons. Tends to be an Attack of the 50-Foot Whatever.

When played straight, this is a case of Artistic License – Biology. See also Radiation Immune Mutants, a Required Secondary Power for some of these nasties..

     Comic Books 
  • There were quite a few radiation created monsters in Marvel's early monster comics, including a fairly adorable weed with mind-control powers and a ''scarecrow'' made giant and mobile by nuclear radiation.
  • In Godzilla: King of the Monsters!, Godzilla fights a yeti which has been turned by nuclear radiation to match it in size and strenght.
  • The French comic Les eaux de Mortelune (The waters of Deadmoon) had mutant animals. Lyon is now inhabited by giant flies, Avignon by giant termites and Les-Baux-de-Provence by giant telepathic praying mantis.
  • Franquin's Idées Noires has one comic about a talk-show debating over the dangers of nuclear energy. A woman calls them to claim that nuclear energy is perfectly harmless since her husband worked in a reactor for 10 years and is fit as a fiddle and that everybody opposing nuclear energy is either a hippy or a communist. Turns out her husband and children are horribly mutated and she sprouted lies just because "There ain't a reason that we should be the only ones affected!"

     Film 

     Literature 
  • Andre Norton's Star Man's Son had mutant creatures in a post-apocalyptic world.
  • Metro 2033. Looks like the heavily irradiated, post-nuclear Moscow became a gigantic nest of monsters, mutants and dinosaurs.

     Live Action TV  
  • The X-Files: Fluke man!
    • More accurately called Tape man... Flukes and tapeworms are both flatworms, but flukes do not have scolexes. Tapeworms do. (But 'tapeman' isn't nearly as cool sounding as 'flukeman'.)
  • The Daleks in Doctor Who were initially explained in "The Daleks" to be the result of a nuclear bomb detonated by the Thals in the distant past. They had locked themselves in metal travel machines to survive the radiation and over many years mutated into something else (although their experiements later reveal them to be a particularly extreme form of Radiation Immune Mutants - they aren't just unharmed by radiation, they need radiation to survive). Most of this was ignored in later appearances and they were completely Retconnned in "Genesis of the Daleks" in the 1970s.

    Professional Wrestling 

    Tabletop Games 
  • All over the place in Gamma World, though modern versions use Nanomachines and Magical Particle Accelerator as an explanation. Some of these include giant insects, the many-legged Centisteed, the multi-armed Snake People called the Menarls, the cactus horse, the humanoid metal-to-rubber-making bunny rabbits called Hoops and The Yexil.
  • Monsterpocalypse has those cosy radioactive giant insects that eat you, instead of making you a super hero.
  • Although it was mainly based on hard science, the After the End game The Morrow Project allowed for radiation-mutated animals that were treated as monsters.
  • Mutant Future had mutated monsters.
  • Paranoia had at least one mutated monster: giant intelligent cockroaches in the adventure "Into the Outdoors with Gun and Camera".
  • d20 Modern's Urban Arcana setting has the Nuclear Toxyderm, a pile of nuclear power plant waste given life.
  • Promethean: The Created has the Zeka, nuclear Prometheans who have the ultimate in Blessed with Suck. Not only do they suffer Disquiet, they spread fallout wherever they go, meaning they can rarely interact with humans and have a lot of trouble undertaking the Pilgrimage. As a result, most of them go Centimanus, and hoo boy, do they go Centimanus. Two NPC examples are Oleg Wormwood (an Eastern European arms dealer who longs to get his hands on a suitcase nuke and start some real fun) and Tsar Bomba (a hulking brute who seems content to just barge into nuclear power plants, subject the staff to a slow death, and bask in the radiation as the place starts to go critical). And that's not even starting on the Carcinomas...
    • Zeka can have a Bestowment (innate power) that lets them irradiate corpses to bring them back as zombies. The Irradiation tree of powers also includes the abilities to control insects and then, later on, to mutate those insects into giants (ala Them). It's also mentioned that the Wastelands created by Zeka tend to include huge, mutated invertebrate lifeforms.
  • Werewolf: The Apocalypse puts a corrupted form of radiation in the hands of minions of the Wyrm. In fact, nuclear fallout is regarded as somewhat holy by the Black Spiral Dancers (werewolves who fell to the Wyrm); one of their greatest sacred sites is a hive under the Trinity test site.
  • Bleak World has the Radio Zombie class of the Experiments. They require a perfect 10 to keep up their human disguises, and get no bonus to keeping it up anyway. Furthermore, their magic and skills make it so that they are built to destroy their opponent, as such it is nearly impossible to maintain a good karma playthrough with the Radio Zombie.

    Video Games 
  • Being inspired in part by 1950s sci-fi and taking place after a nuclear war, the Fallout series has a bunch of these. Mutated animals include roaches, mantises, scorpions, flies, ants, geckos, rats (including Mole Rats larger than an adult human), bears, cows and Tarantula Hawk Wasps.
    • The tarantula hawk wasps were actually genetically engineered by a Mad Scientist. You get to meet him in Old World Blues.
    • Deathclaws. Nobody knows what those came from.
      • Well, some do. Unfortunately, their canonicity is vague, so it hasn't been confirmed that Deathclaws are Jackson's Chameleons genetically engineered by first the pre-War US government and then the Master.
    • Certain Perks can turn you into one. Rad Child and Rad Regeneration makes you regenerate when you have radiation poisoning, and Atomic! makes you stronger and faster when exposed to radiation, on top of giving you a boost to your AP regen.
  • Used seriously, but knowingly, in Metal Gear Solid 3 to explain why some of the animals are bigger (like the tree frogs) or more aggressive (like the gavials) than they are in real life. Para-Medic even compares it to Godzilla.
  • Like their source novel above, Metro 2033 and Last Light have multiple unpleasant types of mutants for Artyom to deal with.
  • In Starcraft II Heart Of The Swarm the Torrasque strain is unlocked after some Ultralisks are hit directly with an experimental nuke, and Abathur incorporates the radiation into their genome.

    Western Animation 
  • The season 5 premiere of Adventure Time implies the Lich was made this way.
    • And "Simon and Marcy" has Simon and Marceline wandering into a ruined city and being attacked by mutated, misshapen creatures who are implied to have been the inhabitants of the city.
    • In "The Vault" Finn's past life Shoko is turned into this after falling into a radioactive river. However, it seems as though the process also caused death by radiation poisoning shortly thereafter.
  • It Came From The Desert suggests this is what created the giant mutant ants.

    Real Life 
  • There has been investigation into whether nuclear accidents like the Chernobyl disaster have mutated animals over generations. It didn't.
    • In Real Life, this wouldn't be able to happen. The nuclear poisoning will kill any higher animal or at least give health problems. The children of given animals may have some abnormalities but usually not good.
      • Scientists discovered that numerous species of birds that lives in the general area of the Chernobyl Exclusion Zone have actually thrived and adapted to the irradiated areas. They began creating more antioxidants that are needed to repel free radicals that would normally age the bird into a premature death.
  • For the ultimate real-world inversion of this trope, check out what The Other Wiki has to say about Deinococcus radiodurans. It's a microorganism (so an inversion on the size front, as well as the radiation-effects front) capable of surviving radiation doses a thousand times greater than what's required to kill a human being. It's a pain in the ass for nuclear reactor operations since it can survive in places where life really shouldn't (like cooling pipes), and it also causes problems with radiation sterilization to preserve food long-term. Being resistant to a whole pile of other things as well, it's known in the world of microbiology as "Conan the Bacterium".
  • Operation Crossroads, the first post-WWII nuclear weapons test at Bikini Atoll, was a serious debacle due to the second bomb in the test being set off under water. Seawater turned out to be a superb transit vector for fallout, and decontaminating the test ships in the operation proved to be utterly impossible. Stafford Warren, the senior medical doctor from the Manhattan Project, realized how dangerous conditions were but he was unable to convince his superiors to cancel the operation for several days. He was finally able to do it by showing them an x-ray of a surgeonfish he had pulled out of the lagoon. The impressive factor was that the fish was so radioactive it had created the x-ray spontaneously when exposed to x-ray film.
