Someone's body is reduced to powder, then reconstituted. Comes in two types: living-to-living and dead-to-living.

Living-to-living is usually {{Phlebotinum}}-based, and may be described as dehydrating the body or reducing it to its "basic elements." It's technically a form of [[HumanPopsicle suspended animation]]. Dehydrated storage on a large scale (a.k.a. "instant {{Mook}}s, just add water") is a usually-comic sub-subtype.

Dead-to-living is usually magic-based, and often uses ashen remains.

Because powder is easily scattered and easily mixed, damage to the reduced body is an implicit possibility, and may result in CameBackWrong. Sometimes (particularly when the method is given as "dehydration"), compact, friable solids are used instead, and the danger is that they will be [[LiterallyShatteredLives crushed]].

[[folder: Anime and manga]]
* In ''Anime/RanmaOneHalf'', any mortal who touches the Kinjakan will have all water in their body be evaporated. This happens to Akane who in her dried up form shrinks to a doll sized version of herself. Only by being exposed to Jusen water will her body rehydrate and be restored to her original size, however it must be done before a time limit is up, as if she closes her eyes she will be gone forever.

[[folder: Film -- Animated ]]

* The dehydration gun from ''WesternAnimation/{{Megamind}}'' turns people, objects and animals into dehydrated cubes. Water turns them back.


[[folder: Film -- Live-Action ]]
* ''Film/BatmanTheMovie'' has a machine that dehydrates living people, turning them into piles of powder which can be reconstituted with water. Accidentally mixing the powders leads to swapping of languages and personality traits. And when The Penguin accidentally reconstitutes some of his mooks with heavy water, this makes the mooks so unstable that a single punch from Batman can completely vaporize them.
* In ''Film/DraculaPrinceOfDarkness'', the title character is reanimated by having his ashes mixed with blood.


[[folder: Literature ]]

* The "essential saltes" in Creator/HPLovecraft's ''Literature/TheCaseOfCharlesDexterWard'' are powdered remains of dead people (or animals), which can be reanimated by sorcery -- but incomplete specimens will [[CameBackWrong Come Back Wrong]].
* In the ''Literature/{{Necroscope}}'' series it's possible to raise the dead by first reducing their bodies to dust before doing the magic (which seems to be a ShoutOut to H.P. Lovecraft -- Brian Lumley has written several Mythos works, after all).
* ''Literature/{{Discworld}}'' vampires are turned to ash if they're exposed to sunlight. They're reconstituted if exposed to blood.


[[folder: Live Action TV ]]

* The ''Series/StarTrekTheOriginalSeries'' episode "[[Recap/StarTrekS2E22ByAnyOtherName By Any Other Name]]" had the [[VillainOfTheWeek Aliens Of The Week]] reduce the Enterprise crew to cuboctahedral blocks of their basic elements. (Picture [[ here]].) [[{{Redshirt}} One character]] was killed by being crushed while in this form; others were restored.
* In ''Series/{{Ultraviolet}}'', the Code 5s[[note]]think what 5 is in Roman numerals...[[/note]] turned to dust when killed and had to be stored in jars or urns. It was noted that they weren't "dead", just temporarily/indefinitely out of circulation. [[spoiler:At the end of the series, we discover that mixing the dust with fresh human blood reconstitutes them.]]
* In one episode of ''MyFavoriteMartian,'' Detective Brennan accidentally gets disintegrated and scattered. Tim and Martin spend the rest of the episode running around collecting his particles so Martin's gizmo can put him back together.


[[folder: Radio ]]

* In one episode of DJ Kenny Everett's science fiction spoof "Captain Kremmen", the eponymous hero is forced to take off on a mission without his crew. Fortunately, his sidekick, Carla, has remembered to bring a packet of Dehydrated Crew for just such an occasion.


[[folder: Tabletop RPG ]]

* The "essential saltes" mentioned under Literature also appear in ''TabletopGame/CallOfCthulhu'', where they are the essential ingredient in the Resurrection spell.
* ''TabletopGame/DungeonsAndDragons''
** Basic D&D ''The Book of Marvelous Magic''. The Urn of Ashes held the ashes of a creature. If treated with blackflame (a kind of anti-fire) they would change back into the living creature.


[[folder: Video Games ]]

* In ''VideoGame/MonkeyIsland2LeChucksRevenge'', there is a potion that can (temporarily) bring a person back from the dead after his body has been reduced to ashes.


[[folder: Webcomics ]]

* In ''Webcomic/LookingForGroup'', one of the characters ended up burnt into a small bagful of ashes. They were resurrected, of course, and were as good as before.


[[folder: Western Animation ]]

* In ''WesternAnimation/DuckDodgersInTheTwentyFourthAndAHalfCentury'', the effects of the [[DisintegratorRay Disintegrating Pistol]] can be reversed by, yes, an Integrating Pistol.
** Another WesternAnimation/DaffyDuck short, "Boston Quackie", has this trope at the end, where the MacGuffin Daffy was delivering to the Slobovian ambassador turned out to be a jar of "Instant Girl".
--->'''Daffy:''' Ya know, there just ''might'' be a market for this.
* The WesternAnimation/BugsBunny cartoon "Hare-Way to the Stars" had Marvin use "Instant Martians" to generate some {{Mooks}} to chase down Bugs. When Bugs accidentally drops a jar of them into a sewer, back on Earth, at the end of the cartoon:
-->'''Bugs:''' [[BreakingTheFourthWall Run for the hills, folks,]] or you'll be up to your armpits in Martians!
* ''WesternAnimation/CountDuckula'' features a version of the "Vampire resurrected by a ceremony involving blood" where the servants of the title character accidentally switch blood with tomato ketchup and thus get a literal VegetarianVampire.
* An episode of ''WesternAnimation/{{Beetlejuice}}'' had the appropriately titled "Party People in a Can". The episode centered on BJ and Lydia having to track them down and dehydrate them since the "Party People" grew very unruly if used under a full moon ([[TooDumbToLive which BJ did]]).
* ''WesternAnimation/Ben10UltimateAlien'': Ma Vreedle used a giant machine in one episode to combine cloning mix and salt water in a bid to create 4 billion Vreedles that would have used the entire ocean.
* ''WesternAnimation/LiloAndStitchTheSeries'': Jumba had all of his previous experiments turned into small gumball-sized pods. They are activated when they make contact with water.
