Healing Vat

Go To

In many science-fiction works, people can recover from practically any injury after being immersed in a tank full of some kind of liquid Applied Phlebotinum that makes them heal with shocking speed. People in them tend to be naked or barely clothed, to show how badly they're wounded and to absorb all the healing juices.

Subtrope of both Auto Doc and People Jars. Related to Panacea, Healing Spring, Healing Potion, and Heal It with Water. May involve Nano Machines.

    Anime and Manga 
  • These are used in Dragon Ball Z by Frieza's minions. They're apparently mondo cool!
  • These kind of devices appear on the Birdy the Mighty franchise (and considering that the titular protagonist is prone to get into fights as befits her Superhero status, she ends up using them rather often).
  • Buso Renkin: Dr. Butterfly spent the hundred years prior to the tart of the series developing a large restoration tank that would allow him to heal the seriously wounded Victor through the power of alchemy and tested it by bringing his great-grandson Papillon back to life after his destruction. After Dr. Butterfly's defeat, Papillon inherits the designs, often using them to heal and revitalise himself.
  • These are located in Fairy Tail used by Tartarus to revive and create new demons.
  • One appears in Ald Noah Zero season 2.

    Fan Works 
  • Advice and Trust: After fighting Zeruel, Rei spent an entire week in a transparent tank full of LCL, healing her body. Ritsuko spent that time observing her and resenting that she was forced to resort to old-fashioned bandages and band-aids whereas Rei had preferential treatment.

  • Star Wars has bacta tanks, using the universal regenerative fluid containing some sort of microbe. Most famously used with Luke in The Empire Strikes Back, and crucial to the plot of the third and fourth novels in the X-Wing Series.
  • Such tanks are used in Starship Troopers to heal wounded soldiers, such as when Rico gets his thigh bitten through by a bug.
  • In Wanted they use vats filled with paraffin wax. It's said to "stimulate white bloodcells and speeds up the process". Wounds that normally takes days to heal do so in hours.

  • In the Paradox series the Chatcaava use a sort of gel to recover from wounds sustained in duels. Alliance ambassador Lisinthir spends a few days in a tank full of it after one fight with the emperor (who had to have his digestive tract re-inserted and was back on his feet that evening.)
  • These show up in the Tour of the Merrimack novels
  • Used in Orson Scott Card's Worthing Saga novel Hot Sleep (it's an inversion of the cold sleep trope, not a sexual reference) when the protagonist is being healed/reconstructed after "proving he's a survivor".
  • Iliff in the Agent of Vega series by James H. Schmitz delivers his final report from a healing vat, after his near-fatal confrontation with the Big Bad of the story.

    Tabletop Games 
  • Eclipse Phase has healing vats, one of the first uses of nanotechnology. Given a few days they can regenerate limbs, and given a few weeks can grant a severed head a new body.
  • Subverted in Warhammer 40,000, where the vats can keep the person alive, but because the victim's injuries are simply too serious (and serious injuries on a Space Marine would kill normal people several times over) they are instead armored, given legs and heavy weapons, and sent off to vanquish the Emperor's enemies as Dreadnoughts.

    Video Games 

  • Played with in Sluggy Freelance, a strip after Torg gets hit with a load of "sleep chaff" shows him in what looks like a bacta tank, then Riff states that it's actually a "bactine" tank and the only reason they can't hear him screaming is the breath mask.
  • When Spinnerette's powers are going critical she wakes up in one of these in Dr. Universe's lab, and smashes it open in a panic. Causing Universe to wonder about the practicality of such things.
  • Most cloning rigs in Schlock Mercenary are giant tanks of water with Nano Machines that rebuild the patient's missing parts, which tend to be everything but the head.
  • In the alien-related continuities of the Walkyverse, Martian resurrection technology consists of a tank in which a corpse is kept, which when plugged into the device causes it to regenerate fully and then return to life.
  • Ballerina Mafia shows Joel making frequent use of a Nanobot healing tube.
  • Such vats tend to be part of resurrection apparati in Girl Genius.

    Western Animation 
  • Danny Phantom was put in one after crash-landing on the yeti world.
  • In Beast Wars both Maximals and Predacons have their own type of healing vat. The Maximals posses a small, airtight, one person chamber, while the Predacons use a vat that resembles a hot tub. In fact Megatron is seen bathing in one on multiple occasions, complete with a rubber ducky.
  • Vilgax of Ben 10 spends most of the first season inside one after the vessel carrying the Omnitrix caused his ship's bridge to explode with its counterattack. After coming out, his body was augmented with muscle enhancing implants to make him even stronger.
  • In Batman: The Animated Series, Batman has one in the Batcave. He uses it as a "hot chemical bath" (!) in "Heart of Ice" to treat a low-level thug who'd just been on the receiving end of Mr. Freeze's ice-gun.
  • TRON: Uprising: The title character has to rely on one stored in his hideout due to injuries and malware, staving off Critical Existence Failure from the damage.
