** Rupters do not evolve further, but infect non-parasite mobs with the Call of the Hive, which slowly assimilates those mobs. Assimilated Mobs can spread COTH to non-infected mobs to Assimilate them.

* AdaptiveAbility: One of the driving characteristics of the parasite invasion. More directly, tiers of parasites past Primitive can adapt to individual sources of damage (such as melee or ranged), reducing their effectiveness over time. The only way to counter this is by [[AttackItsWeakPoint cutting off their tentacles]], but that risks giving it the [[TurnsRed Rage buff]]...

** All parasites are weak to fire and lava. Fire is also the one source of damage that a parasite can never adapt to. However, even that might not work if they're [[HomefieldAdvantage spawned in a Parasite Biome]], where they can receive the [[ImmuneToFire Fire Resistance]] buff upon spawning.

** Beckons are an odd case. They can appear via one of many ways -- having a chance to spawn when a Parasite dies, by Stage IV Beckons, on the Infested Blocks that other Beckons turn normal blocks into, or on Residue which can be spawned by Hosts, Adapted Parasites or converted from Infested Blocks if a Stage 1 Beckon dies. Beckons slowly grow from Stage I to Stage IV, with each stage capable of producing biomass that spawns other types of Parasites, the types of which get stronger per Stage (Stage IV only spawns ''other'' Beckons from Stage I-III).

* BossInMookClothing: Like their ordinary cousins, Assimilated Endermen are incredibly beefy for being relatively early-game mobs. In addition to keeping their immunity to projectiles, they deal 13 damage per hit, lose their weakness to water, and even [[FlunkyBoss teleport other assimilated mobs]] into battle!

** Buglins emit a slimy squelching noise, which while off-putting, helps players hunt them down before they can infect other mobs.

** All parasites are weak to fire and lava. Fire is also the one source of damage that a parasite can never adapt to. However, even that might not work if they're [[HomefieldAdvantage spawned in a Parasite Biome]], where they can recieve the [[ImmuneToFire Fire Resistance]] buff.

** When an Assimilated Mob kills enough hostile mobs, it and three other Assimilated Mobs around it will turn into Moving Flesh. The four Moving Flesh will then [[FusionDance merge together]] and form into a Primitive Parasite.

** Beckons are an odd case. They can appear via one of many ways -- having a chance to spawn when a Parasite dies, by Stage IV Beckons, on the Infested Blocks that other Beckons turn normal blocks into, or on Residue which can be spawned by Adapted Parasites or converted from Infested Blocks if a Stage 1 Beckon dies. Beckons slowly grow from Stage I to Stage IV, with each stage capable of producing biomass that spawns other types of Parasites, the types of which get stronger per Stage (Stage IV only spawns ''other'' Beckons from Stage I-III).

** When an Assimilated Mob kills enough hostile mobs, it and three other Assimilated Mobs around it will turn into Living Flesh. The flesh will then merge together and form into a Primitive Parasite.

Upon first starting a world, all seems normal. There's only the occasional Buglin: a black grub about the size of a Silverfish, only able to run away from mobs. As time passes, they will grow into the much more dangerous Rupters, which will seek out mobs to [[TheVirus assimilate]] into fleshy monsters. These assimilated mobs will continue to kill, infect, and merge into progressively more powerful {{Eldritch Abomination}}s, up until the world itself slowly morphs into a rotten, hostile EldritchLocation.

The infestation cannot be cured, nor can it be stopped. The only hope is using Lures to stall the rate of infection, and even these won't guarantee safety from the neverending parasite swarms.

* ColorCodedForYourConvenience: The Adaption System works this way. Red particles mean a mob is taking regular damage. Yellow particles and a green flash means a mob is in the process of adapting, reducing their damage taken. Once a mob flashes purple, it is [[NoSell completely immune]] to that specific damage type.

* DaylightHorror: Parasites don't burn in the sunlight. Though they (usually) only spawn at night, they tend to linger throughout the day.

* DefeatEqualsExplosion: Occasionally, a killed parasite will burst into piles of viscera, clouds of poison and COTH, or [[MookMaker Buglins]].

* EliteMooks: Adapted parasites to their Primitive counterparts.

** While a new Beckon might not be noticed from across the map, its DramaticThunder can be heard from anywhere in the world - [[ParanoiaFuel especially if the skies are clear]].

* HostileTerraforming: High-tier Beckons have the ability to spawn Nodes, which gradually convert the world into [[SicklyGreenGlow infested blocks]], and later a unique "Parasite" biome.
* IncrediblyDurableEnemies: Only the Buglins, Rupters, and a few of the smaller Assimilated mobs have similar or lower health than most vanilla creatures. Everything else can take huge amounts of punishment before going down, and their AdaptiveAbility only makes them even more durable.

** All parasites are weak to fire and lava. Fire is also the one source of damage that a parasite can never adapt to. However, even that might not work if they're [[HomefieldAdvantage spawned in a Parasite Biome]], where they get Fire Resistance I as an effect.

* LightningBruiser: Several Primitive, Adapted, and Pure parasites sport huge amounts of health, insane attacking power, and can be very fast at chasing you down.

* ScaryTeeth: One of the more uncanny traits of the assimilated mobs are articulated jaws with teeth, particularly for those that don't usually have a separate one.

* TheVirus: Call of the Hive (often abbreviated to COTH) is a potion effect that mimics an infection. If a mob has the effect, it will gradually transform into an assimilated version of itself. Later stages give mobs a chance to spawn in with COTH already applied. Not even the players are immune, and an [[AndThenJohnWasAZombie infected player that dies spawns an Assimilated Adventurer]].

** The Rage effect halves the cooldown on parasite abilities.
** Longarms take it even further. For every health lost, their damage increases by 50% or 100% for Primitive and Adapted versions respectively.

* ImprovisedWeapon: The Crux is capable of picking up blocks and throwing them at the player to deal massive damage.

* KillItWithFire: All parasites are weak to fire and lava. Fire is also the one source of damage that a parasite can never adapt to. However, even that might not work if they're [[HomefieldAdvantage spawned in a Parasite Biome]], where they get Fire Resistance I as an effect.

* KillItWithFire: All parasites are weak to fire and lava. Fire is also the one source of damage that a parasite can never adapt to.

* CycleOfHurting: Assimilated Adventurers, in certain situations. Since they can spread COTH to players, dying to one will often spawn another in its place. If a parasite gets into your bedroom, even that MercyInvinicibility won't do you much good.

** Each Evolution Phase has its own accompanying ScareChord. Listen to them [[https://youtu.be/3rd7DehIg8c?t=26 here]].

* ScareChord: Evolution Phases have one for whenever they go up, along with a single-word announcement in chat.

* AndThenJohnWasAZombie: If a player is infected with Call of the Hive and dies, they spawn an Assimilated Adventurer behind that will be wearing their previous armor (except chestplate).

* HealingFactor: Parasites that aren't Inborns, Crude tier, or Beckons heal very quickly when out of combat.
* HostileTerraforming: High-tier Beckons have the ability to spawn Nodes, which gradually convert the world into [[SicklyGreenGlow infested blocks]], and later a unique "Parasite" biome.
* MookMaker: Beckons are immobile support structures that not only spawn continuous amounts of parasites, but also allow them to grow to Primitives and beyond.

* TurnsRed: The Rage effect halves the cooldown on parasite abilities.

* TheVirus: Call of the Hive (often abbreviated to COTH) is a potion effect that mimics an infection. If a mob has the effect, it will gradually transform into an assimilated version of itself. Later stages give mobs a chance to spawn in with COTH already applied.

* NintendoHard: Primitive, Adapted, and Pure parasites are extremely formidable foes, even for those with fully enchanted diamond armor. A fair number of them can deal 20 or more damage in a single hit, assuming they don't have an [[DeathOfAThousandCuts absurdly rapid attack]] to begin with - not to mention their massive health pools, adaption to damage, and frequent use of block-breaking abilities. As for Ancient parasites... good luck.
