[@ixiahj]

This is correct. Its a symbiotic relationship, not a parasitic one. The trill host benefits from their symbiote because they gain all the experience, knowledge and memories of all the past trills that were once joined with their symbiote. While the symbiote gains the opportunity to experience all sorts of things through out their host trill's life time instead of just being an immobile slug thing.

[@ixiahj]

@@bweakland2003 I'm pretty sure it goes both ways. If the symbiote is removed, the trill dies. But if the symbiote isn't placed in a compatible host, it too will also die. In Jadzia Dax's case, the trill's name is Jadzia but the name Dax is the symbiote's. They don't distinguish between previous host or current host. They are one and the same entity once joined. There's a reason why Sisko always calls her "old man." Curzon Dax was his friend.

One other major thing that adds to the danger of the flood, is their ability to use technology. Unlike most monsters, which go around punching, clawing, ripping, and biting people.

Pretty much. Only viral reproductive creature I might consider worse than the flood is the replicators from stargate. Those little bastards were created for one purpose, strip anything in sight to make little LEGO bricks for more replicators. When they strip mined one planet to the point it would collapse on itself, then form themselves into a space ship, and find the next planet. Any tech they came across would be assimilated, and since they had a proper hive mind, the more there were the smarter they got.

[@reallogex1607]

Well, it is stated a lot of times that the Symbiont (for example the Dax Symbiont) merges with its Host (Lets just take Jadzia) to form a new person from the merged personalities and experiences. Thus Dax and Jadzia become Jadzia Dax, practically a whole new person which is really not just the "menacing worm thing" taking over a person, but rather, well, merging with them. It seems beneficial to both parties involved. Also it is literally called Symbiont as in Symbiotic relationship, which is different from a parasite which exploits its most of the time unwilling Host.

Who's to say the Thing wouldn't also develop something similar to a grave mind if allowed to spread to a global infestation?

[@Runedragonx]

To elaborate on the Flood, this is a rough timeline. The Precursors were a tier 0 race that created all existing (civilized) species in the Halo galaxy. They originally bestowed the Mantle of Responsibility unto the Forerunners, but later found their choice species unfit, so they have the Mantle the the Ancient Humans. Angry at this outcome, the Forerunners waged a galactic war against the Precursors, and they were winning. In an effort to preserve their own species, the Precursors, being able to bend the laws of physics with their tier 0 tech, dismantled themselves into a 'dust'. Still sentient, but entirely immortal. Over uncountable years, they grew with resentment, corrupting their previous notions. At this point, Ancient Humanity found a protein rich particulate, and decided that, being so abundant in the local space, it would make a great feed for livestock. Oh, how they were wrong. The sentient particulate began to assimilate the flesh of these lowborn creatures, and thus, the Flood was born. Humanity ran, ran faster than ever to get away from the monstrosities that presented themselves, quickly finding their ships in Forerunner space. They began purging infected worlds, an act of war in the Forerunners' eyes, leading to the Human-Forerunner War. At the end of this war, the Forerunners forcibly devolved Humanity, and swiftly thereafter found this, "Flood," something assumed to be an imaginary scapegoat for the Humans, to be a real threat. The Forerunner-Flood War was in full effect, they tried everything, did everything, studied everything… to no avail. Finally one Forerunner, the Ur Didact, concluded that the Halo array was the only possible plan that would succeed, while the Didact (not of the Ur variety) dismissed these claims, dead set on finding another way. That is until Mendicant Bias, their super AI that controlled *literally* their entire spaceborne military, was affected by the Logic Plague, the Flood's way of infecting intelligent programs. At this point, with all hope lost, the Halos truly were the only way, but first, the construction of another AI, one that could outsmart Mendicant and his hubris. Once the battle of the computers was finally over, the new AI was shut down to protect it's 'mind' from the Flood, opting to continue manually. Finally, the collection and sorting of all species in the galaxy, the firing of the Halos, and the seeding of worlds. With this final act, those whom survived left the galaxy in shame, leaving the Mantle behind, and branding Humanity as, "Reclaimer." Enter, the beginning of anthropologic prehistory and onward. Everything that has happened, and is happening now-onward, is technically part of the Halo lore.

Midichlorians, the most dangerous weapon of the space wizards.

[@mandyrobbins1041]

And again, they fail to take into account it's not JUST the concentration of Midiclorians that differentiates between Jedi and Sith...it's the ideologies behind each group...defense of civilization as a whole vs. seeking personal power for the sake of power and domination. It's the very nature of the two sides that is flawed. "Grey" Jedi...those that serve the Living Force...like Quigon and Ashoka in Canon and even Ben Skywalker in Legends/EU (which Disney had NO right to abolish as "non-canon" are those that follow the true nature of the Force. Even though it was a dangerous line, even Mace Windu was closer to the true path. Due to Va'paad, he could channel his Dark Side emotions while serving the light, as it was a variant of Form 7 of LIghtsaber Combat. This variant made it especially effective against the Sith or other Dark Side Force Users...not only could it harmlessly channel the user's own dark side influences without corrupting the Jedi, if they mastered it: It could also send back Dark Side energy sent at the user. That's how Mace Windu came so close to defeating Sidious in the prequels.

@Joseph Douek Except that even in Canon, it’s stated by the Whills that there is no Dark or Light Side of the Force. There is just the Force, good and evil are concepts used by mortal beings, and have no real meaning to immortal entities besides being words to them. That same line of thinking is used by Grey Jedi, who see the Force for what it is, a power that flows through everyone and everything, no matter their moral compass. The ways in which the Force is used changed depending on who used it, though the differing ideals led to multiple wars between the Jedi and Sith. The reason that the Sith are always "destroyed" to bring balance is because Jedi are no longer necessary at that point. Without Jedi or Sith, there is balance once more.

Generation Films 240K subscribers Star Trek has a lot, and I mean A LOT of hostile alien parasites. Remember in Star Trek: Enterprise season 3 episode "Countdown" where Reptilian Commander Dolim had his soldiers infect communications officer Hoshi Sato withe parasites that caused her great pain to make her give the Xindi Reptilian's the final launch codes for the Xindi Weapon in order to destroy Earth?! I will never ever forget that scene.

[@denisloebner4882]

A few that come to mind: Immulsion from the gears of war series, Tiberium from c&c, the Borg from Star Trek, Mantrids drone arms from Lexx. The latter is easily number 1 succeeding in taking over all matter (apart from the heroes and their ship) in the whole universe.

[@MegaSkrow]

how about the borg nanites? yes they are mechanical not biological but they do behave quite like parasites

[@lightbower5826]

they´re a virus

[@zvpunry1971]

@@lightbower5826 No, they aren't a virus. A virus is the information that encodes instructions to create virions. The information can be stored in RNA or DNA and can even be copied into the DNA of its host. A virion is the infectious particle that most people think of when they talk about viruses but it is more then the virus, it is the protein shell that encloses the virus and some supporting proteins that allow the virus to enter the host cell. Almost all depictions of borg nanobots (just more common word for nanite) show a giant object that grabs another giant object, a red blood cell. I call them giant, because they really are, compared to a typical virion. The typical diameter of a red blood cell is 6-8 micrometer (6000-8000 nanometer). The borg nanobots have a similar size, so they are more like microbots. In comparison, the virion of the SARS-CoV-2 virus has a diameter of around 100 nanometer, the RNA that is inside is a long but thin molecule with a diameter of about 2-3 nm. This is what really deserves the nano prefix. And there are real nanobots. In our cells are tiny nanobots, called ribosomes. Their diameter is about 20 to 30 nanometer. They execute the instructions encoded in our genes and produce the molecules that they encode. And they don't care if they execute our normal genes or the genes from a virus. If they happen to execute the virus genes, they produce virions until the cell dies and releases them. And then they happen to infect other cells or get coughed out where another victim might inhale them. Is a virus a parasite? Maybe a collection of parasitic genes.

[@ThatMetroidGuy]

Whether it be a film, game, novel or whatever, when it comes to top parasites you have to have Flood at number one every time, even if it's a video about parasites in films exclusively. The Flood is that powerful.

[@buggyboy2849]

People write the Zerg off as Tyranid wannabes but if you really dig into their lore and not the gameplay restrictions they suffer from in the games you can see they'll stand a chance against the Flood and Nids... Any organism that evolves in a matter of seconds and produces a virus that mutates constantly is something you don't want to mess with...

SOP on away missions is environmental suits and survival gear even if the environment seems safe. As soon as I received command of the Resolute I placed my standard SOP (standard operating procedure). Lots of gamers would call this meta gaming ,I would say common sense. Look at how many episodes of StarTrek went awry because of this. It would be standard protocol by now. My Gamemaster has to be more creative than that .

The Uhl from Starflight and Starflight 2 is a little twist on the trope. The Uhl itself is one life form spread across many parsecs of space, bound together fairly loosely by electromagnetic radiation, that gets disturbed by sentient life. To counteract this, it tunes itself to the frequencies of the sentient race most suitable, thereby taking control of the sentients' brainwaves to use them as antibodies to keep its body safe from other sentients. Not even the simultaneous detonation of six supernovae was enough to kill it.

[@DonVigaDeFierro]

Yes, in some versions they inject a viral vector that forces the host's cells to "grow" a chestburster. That is why some xenomorphs acquire its host's characteristics. It's all technobabble (biobabble?), but that is one of the official explanations.

[@colinsmith1495]

I have to disagree with the Trill Symbiote. Your whole justification for having them on the list at all is that they get more out of the bond than the host? One side almost _always_ gets more out than the other. That doesn't make the symbiote 'dangerous'. The fact that it gives the host anything at all makes it mutualistic symbiosis. Unless you start analyzing how much personality is transferred to the host (which is actually wildly inconsistent in the series), there's no grounds to call them 'dangerous'.

The magog from the show Andromeda reproduced by biting people and injecting saliva which contained their eggs. The eggs would then hatch and consume the host. There's also the vampires from the Strain. The vamps inject the victim with tiny worms from their tongue-like proboscis which multiply and take over the host turning them into a vampire.

The Nemesis-Alpha is all right, but if you're looking for a Resident Evil parasite, Las Plagas is probably a bigger deal. As a side note, the order of medieval knights that contained and sealed off the original Plagas outbreak must have been hardcore beyond belief. Leon and Ada are walking arsenals armed to the teeth with guns, grenades, and a helicopter gunship at one point, and it's barely enough to keep them ahead of enemies who aren't very bright and are overwhelmingly melee-only. The knights, though? Facing that same mob of cultists and monsters, but with only sword, shield, and shining armor? That must have been some Dark Souls-level badassery.
