''Slimer'' is a 1983 science-fiction/horror novel by "Harry Adam Knight," a.k.a. Australian author John Brosnan, writing under a pseudonym. Brosnan also wrote the novels ''{{Literature/Carnosaur}}'' and ''The Fungus'' under this name. The novel was co-written by English author Leroy Kettle, however Kettle went uncredited. The novel was adapted in a 1995 film called ''Film/{{Proteus}}'' by Brosnan himself.

Paul Latham, his girlfriend Linda Warner and their four friends Alex, Rochelle, Mark and Chris had been on a drug run from Morocco when their yacht sank. They had to abandon ship so quickly they lost all of their drugs (except for Alex's personal stash of heroin). By a seeming stroke of luck, they stumble across a seemingly abandoned oil rig. Going aboard, they discover the rig is actually a cover for a top secret lab run by a company called Brinkstone.

Some exploring reveals discarded, unfired guns and scattered, empty clothes. That night, a mysterious, unseen creature attacks them. Although Paul empties an M16 into it, this doesn't seem to harm it. They come across a scientist named Dr. Shelley who says the creature is nicknamed "Charlie" and won't harm them again. Although he promises he'll explain more later, he is missing the next day. Later a security officer confronts the group, offering to help, but before their startled eyes turns ''into'' "Charlie," a monstrous creature which wounds Rochelle.

Paul and the others eventually discover that "Charlie" is actually a great white shark given shapeshifting abilities by an experimental compound called "Phoenix." It absorbs the minds and bodies of its victims, and can take their shape, and they're next. To make matters worse, the increasingly hostile Alex begins antagonizing everyone at every turn, questioning Paul's leadership and threatening to be as dangerous to the group as the monster itself.

Has nothing to do with the green ghost of the same name from ''{{Film/Ghostbusters}}''.

!!Tropes used in this novel:
* AccidentalMurder: [[spoiler:Paul shoots one of the helicopter pilots at the end, mistaking him for one of Charlie's forms.]]
* ActionSurvivor: Paul and Linda.
* TheAggressiveDrugDealer: Alex.
* AllGirlsWantBadBoys: The reason for why Rochelle is with Alex.
* AnatomicallyImpossibleSex: Of the "plain impossible" variety. See CruelAndUnusualDeath below.
* AndIMustScream: The fate of Charlie's victims.
* [[AndThenJohnWasAZombie And Then Buckley Was A Zombie]]: And then Rochelle. And Alex. And...
* ApocalypticLog: Dr. Shelley's video tapes.
* ApocalypseHow - Planetary Class 3: What would occur should Charlie survive GoingColdTurkey (see WeaksauceWeakness below) it could go on to reproduce itself and absorb everything and everyone on Earth and supplant the human race entirely.
* AssholeVictim: Alex. [[spoiler:And Mark after his DespairEventHorizon causes him to turn into a real JerkAss.]]
* ArtisticLicenseBiology
* BioPunk
* ChekhovsSkill: Paul has some passing knowledge of how to fly a helicopter. [[spoiler:This saves him and Linda when the pilot of their getaway chopper turns out to be Charlie in disguise and he has to fly the craft himself.]] In a nod to realism, though, he isn't terribly good at it and almost kills them trying to land.
* ClosedCircle: Except for the beginning where the castaways are in the life raft, and the ending where they're in the helicopter, all the action takes place on the oil rig.
* CombatTentacles: Charlie can unleash these if he wants to.
* CruelAndUnusualDeath: [[spoiler:Poor Chris. How many people can say in the afterlife they died getting raped to death with a [[ItMakesSenseInContext giant wang of doom]]?]]
* DaylightHorror: Most of the action takes place in the lab's very brightly lit white rooms and corridors.
* DespairEventHorizon Mark suffers one when [[spoiler:Chris]] is taken by the creature.
* DevelopingDoomedCharacters
* DrugsAreBad: Except when they save the day!
* DyingAsYourself
* DwindlingParty: Although it takes a while for Charlie to start whittling the group down.
* EagleLand: Alex Rinaldo is the lone American in the group (a ''Mexican''-American to be precise, not that this seems to make much difference) and at one point touts the US as "the greatest country in the world." The American helicopter pilot at the end also brags that "we have the death penalty where ''I'' come from!"
* EmptyPilesOfClothing: All that is left after Charlie absorbs its victims. Interestingly, Charlie has the ability to morph clothing, as when the absorbed people's minds surface and alter Charlie's form to "themselves," they don't appear naked, but instead are wearing clothing that is attached to their bodies and can't be removed.
* EverythingIsBigInTexas: Mr. Brinkstone is from Texas. "Being from Texas," comments Dr. Soames, "he doesn't think small."
* EvilIsVisceral
* ExtraEyes: When in the form of [[spoiler:the second helicopter pilot]] Charlie grows an extra eyeball in the back of his head to watch Paul and Linda in the back seat. Creepy.
* FaceFullOfAlienWingWong: After Charlie evolves from absorbing individual people into itself and moves on to "converting" humans into more of its new mutant shark species, it uses a penis-like barbed claw dripping a fluid to "impregnate" [[spoiler:the helicopter pilot]] and later tries to do this to Paul aboard the copter when impersonating [[spoiler:the pilot]]. It even refers to this as "giving its seed" to people.
** [[spoiler:Alex]] is essentially French-kissed to death by Charlie in the form of Rochelle, who forces "her" tongue down his throat to take him over.
* FunctionalAddict: Mark.
* TheGhost: Lloyd Brinkstone, the owner of the Brinkstone company, who is mentioned several times in Shelley's [[ApocalypticLog video tapes]] but never actually appears. He does however appear in ''Film/{{Proteus}}''.
* GoingColdTurkey
* GoneHorriblyRight: The Phoenix experiment, according to Shelley. They worked hard to design something that could survive almost ''anything'' and boy howdy, they sure succeeded!
* HellishCopter
* AHouseDivided: Much like in ''[[Film/TheThing1982 The Thing]]'', there's a great deal of paranoia among the characters about who the monster is.
* IKnowYoureInThereSomewhereFight
* ImpostorExposingTest: Sort of. Paul's idea of one is to point a loaded gun at the person in question and threaten to shoot them if they can't prove they're not the creature.
** FridgeLogic: This threat makes little sense, however, because by this time the group is already aware that bullets don't kill Charlie.
* KillItWithFire: Tried against Charlie. It hurts it, but doesn't ultimately do any lasting damage. [[spoiler:In ''Film/{{Proteus}}'' the trope is played straight and this succeeds in killing it at the end.]]
* LampshadeHanging: A lot of the dialog consists of the characters commenting about various tropes and cliches in horror movies.
* LostAtSea
* MarketBasedTitle: It's titled ''Gen'' in Poland.
* NewAgeRetroHippie: Chris. She is an animal rights activist, outspoken and liberal politically, insists she has psychic feelings, and is into "crystals," whatever ''that'' means.
* NiceJobBreakingItHero
* NinjaPirateZombieRobot: Charlie is a mutated, shapeshifting, heroin-craving super-intelligent great white with tentacles.
* RapeIsASpecialKindOfEvil
* StockUnsolvedMysteries: Someone brings up the ''Mary Celeste'' and compares it to the deserted rig.
* ThreateningShark: Charlie used to be a regular great white shark. Now he's a shapeshifting monstrosity.
* TookALevelInBadass: [[spoiler:Linda actually is the one who defeats Charlie at the end, and comes up with the idea to distract him enough for Paul to boot him out of the helicopter]].
* TwentyMinutesWithJerks: Except for levelheaded Paul, everyone is either a thoroughly unpleasant person or never stops whining.
* UtopiaJustifiesTheMeans: The entire Phoenix experiment was begun because Lloyd Brinkstone basically wanted to save humanity.
* VoluntaryShapeshifter: Charlie, to an extent. Although he has a physical form, he can turn himself into a liquid state to flow underneath doors and through air vents.
** InvoluntaryShapeshifting: Sometimes the minds of the absorbed victims can override the main consciousness and forcibly turn Charlie's body into theirs. It's only temporary, though, and after regaining control, Charlie retaliates with some InvoluntaryShapeshifting of his own, forcibly turning the body back into his own.
* WeaksauceWeakness: [[spoiler:The seemingly invincible Charlie's weakness turns out to be drugs, which is discovered when it absorbs heroin junkie Mark, who had just shot up. The mutant is essentially defeated by being turned into a heroin addict!]]
