[[folder:The Player]]

The nameless player starts off with a copper short sword, a copper pickaxe, and a copper axe, along with a carrot to summon a bunny if they bought the collector's edition. The player can also be joined by others in multiplayer.
----
* {{Badass}}: Over the course of the game you will run into various [[EldritchAbomination unspeakable horrors]], and if you are armed and prepared enough, you can [[DidYouJustPunchOutCthulhu KILL]] said horrors in combat,[[UpToEleven then take it even further by FARMING them]].
* CurbStompBattle: Is a practitioner of this. Regardless of play class, if you can't find an enemy that is able to keep up with you in [[LightningBruiser speed, strength]] [[MightyGlacier or power]] then chances are the fight is going to be over with either little to no damage taken and the enemy ''utterly obliterated''.
* DidYouJustPunchOutCthulhu: Essentially every single boss fight. Special Mention goes to [[spoiler: beating The Moon Lord, who looks pretty much like Cthulhu himself and is his brother.]]
* FeaturelessProtagonist: The game sports a numerous amount of customizations for your character, meaning that you can add your own personal touch to the character so it looks the way you want it to. And it's played straight in all of the NPC dialogue; the only feature [=NPCs=] will ever comment on is whether you're a boy or a girl, and even then only sometimes.
* NiceJobBreakingItHero: By killing the Wall of Flesh, the Player turns a slightly corrupted world into one threatened to be overrun by huge, competing, pockets of [[{{CrapsaccharineWorld}} hallow]] and [[{{CrapsackWorld}} corruption or crimson]].
* OneManArmy: The player finds themselves facing a lot of enemies in their journey, and provided he has the skill, equipment and health, can mow them all down ''en masse.'' Heck, the player even takes on whole armies in the various wave events and if you are ready for them, [[UpToEleven then you can turn the attack into]] [[CurbStompBattle a massacre for the invading army.]]
* PersonOfMassDestruction: Regardless in one way or another, the player will cause a lot of destruction on their travels.

!! Non-Player Characters

All NPC's can move into a player's town if they have, a room with light, a large item (such as a table, dresser, bookshelf, etc.) and a comfort item (such as a chair, bench, bed, etc.), a door and some criteria specific to the NPC.

[[folder:The Guide]]
The first NPC, who you start out with in every world. As befits his name he guides you with tips of varying levels of helpfulness, and if you show him any material item he can tell you what can be crafted from it.
----
* TheScrappy: Invoked. He got hate from the beginning for appearing in every world, being unkillable, and subject to mass ArtificialStupidity. At this point he's even become the scrappy ''in-game'', with other [=NPCs=] occasionally making comments about how much they hate him.
* TheSmartGuy: Supposedly. He does know a lot, but is still subject to the occasional ArtificialStupidity.
* TheStraightAndArrowPath: Uses a Wooden Bow to defend himself if forced into combat.
* VoodooDoll: First hinted at by the Arms Dealer before they are found being carried by voodoo demons in the underworld. Equipping it as an accessory allows you to actively harm the guide with whatever weapon you had and throwing it into lava also vaporized the guide with it. [[spoiler: Should it be thrown into lava in the underworld then it summons the Wall of Flesh]].
[[/folder]]

[[folder:Merchant]]
As the player amasses more money the Merchant will appear to relieve them of that burdensome cash. He sells mostly general use items, some potions, and spare tools in case the player loses theirs and lacks the materials to make more.
----
* HonestJohnsDealership: Judging by his dialog. He's constantly trying to foist off items of dubious usefulness like "perfectly ventilated armor", despite his claims of not being a junk dealer he's tried to sell useless angel statues to other [=NPCs=], and he sells dirt blocks for exorbitant prices on the international market.
* KnifeNut: If forced into combat, he will defend himself with throwing knives.
[[/folder]]

[[folder:Nurse]]
The nurse will move in once a player has found a heart crystal to expand their maximum health above the starting 100. She can heal the player the player and remove any debuffs.
----
* AllPeriodsArePMS: All of the female characters get ''really'' nasty during a Blood Moon, which the devs have confirmed is a joking reference to periods. The Nurse is no exception, as her lines become various levels of bitchy, either accusing the player of being a hypochondriac or complaining that they dare to get injured.
* AmusingInjuries: Several of her lines has her casually mentioning re-attached body parts or other grievous wounds.
* CombatMedic: Will heal herself or other wounded [=NPCs=] after attacked, and when not helping her allies stay alive she'll be fighting off enemies witn Poisoned Knives.
* DrJerk: She tends to become a bit of a sarcastic prick, especially when [[BerserkButton the player wants her to heal them at high health]]. Approach her on the brink of death, [[JerkWithAHeartOfGold and she'll quickly lose this attitude]].
* HealingShiv: She also throws what look to be needles at the [=NPCs=] to heal them, and will occasionally use them to heal herself.
* HelloNurse
* KnifeNut: Throws Poisoned Knives to fight, and needles to recover her friends.
* {{Tsundere}}: The Nurse can come off as this: Some of her quotes suggest a TeamMom mentality, others that she only sticks around because you pay her.
* TurnYourHeadAndCough: One of the random quotes when you talk to her, even if your character is female.
[[/folder]]

[[folder:Painter]]
He's a painter, dressed in a red cap and white overalls. He sells everything you need to paint your world, as well as a number of decorative paintings, particularly landscapes.
----
* AbnormalAmmo: Uses a Paintball Gun in self-defense.
* ShoutOut: Makes several references to other painters, particularly [[Series/TheJoyOfPainting Bob Ross]].
[[/folder]]

[[folder:Dye Trader]]
The dye trader moves in when you have found any item that can be used to make dyes. He sells the dye vat along with brown and silver dyes, and in exchange for Strange Plants he will give you animated and/or highly colorful dyes.
----
* ColorCodedMultiplayer: In a multiplayer server, he sells Team Dye that changes the color of the armor/clothing that it's applied to the respective color of the team if you are on one.
* SinisterScimitar: The weapon he uses to fight is explicitly called "Exotic Scimitar"
[[/folder]]

[[folder:Demolitionist]]
A dwarf who moves in after you find grenades/dynamite or craft sticky bombs and can sell you more of them and with many other explosive products.
----
* AxCrazy: This guy is a little too fond of explosive tumult.
* GrenadeSpam: Defends himself through the use of Grenades.
* LeaningOnTheFourthWall: If you talk to him, he may ask you to sign a "Griefing Waiver".
* OurDwarvesAreAllTheSame: He has many of the stereotypical dwarf's traits. He is significantly shorter than other [=NPCs=] and has a beard. Furthermore, his mining helmet, lantern, and the fact that he sells Explosives fits the trope of dwarves preferring underground environments.
* TheRival: To the Arms Dealer.
* StuffBlowingUp: His specialty.
* YourAnswerToEverything: Got a problem, ''any'' problem? Easy - blow it up.
[[/folder]]

[[folder:Angler]]
An NPC introduced in 1.2.4 sleeping in the ocean. He gives out rewards upon giving him a specific fish.
----
* BrattyHalfPint: The only child NPC in the game, and the most annoying character in the game. At times he even refers to the player as an errand boy.
* ConvenientlyAnOrphan: He may occasionally mention that he's parentless, which partially justifies why he can be found in the middle of nowhere in the CrapsaccharineWorld that is this game.
* InfantImmortality: He can be hurt by monsters or traps like the other townsfolk, but instead of dying bloodily like the others, he vanishes in a puff of smoke with the message [[ScrewThisImOuttaHere "[name] has left"]] when his health runs out.
* {{Jerkass}}: This kid has nary a redeeming feature. He's an egotist who actively pulls cruel pranks on his neighbors and views the player as nothing more than a personal slave.
* KnifeNut: Throws [[ShamuFu Frost Daggerfish]] to fight.
* NonStandardCharacterDesign: So far the only NPC that is shorter than everybody else, due to being a child.
* SmallNameBigEgo: Everyone else in his eyes are his underlings, despite the fact that unlike him they're all adults with a myriad of useful skills and wares.
* SpoiledBrat: He frequently screams that he wants the daily quest fish immediately.
[[/folder]]

[[folder:Stylist]]
A new NPC introduced in 1.2.3 that is found inside a spider nest, [[DistressedDamsel bounded by webs]] and can be freed. She can change your hair style. She also sells various hair dyes.
----
* AxCrazy: DownplayedTrope as she's only this on blood moons. The other female [=NPCs=] only go as far as telling you not to bug them. This one? She will threaten to go Sweeney Todd on you with her styling tools if you don't leave her alone.
* AllPeriodsArePMS: During the Blood Moon, which the devs have confirmed is a joking reference to periods, she threatens you with her [[{{ImprobableWeaponUser}} scissors and razor]].
* ColorCodedMultiplayer: In multiplayer servers, she sells Team Hair Dye that makes the player's hair change colors depending on what team they're on.
* DiegeticInterface: Many of her hair dyes can be used as ''Franchise/DeadSpace''-style indicators such as life, mana, depth, biome, team, time, etc.
* HairstyleMalfunction: Possibly. Upon her death, her head and hair split into two different chunks, unlike other long-haired NPC[=s=]. What little hair is attached to her head is a spiky, unshapen mess, and it might not all be that surprising given how she might complain of her hair being loaded with spider web when you rescue her.
* TheFashionista: She's all about the freshest hair styles, defends herself with Stylish Scissors and has got a nice dress and pair of high heels.
* ShearMenace: Uses Stylish Scissors when forced to fight monsters.
* SeriousBusiness: Bad hair days. She may mention a disasterous attempt to dye her hair using some of the Dye Trader's stock or comfort the player if they supposedly have an awful hair problem.
[[/folder]]

[[folder:Party Girl]]
The party girl moves if you have at least 14 NPC[=s=] living in houses, with a 2.5% chance of doing so each day while the population remains at or above that number. She sells party supplies, including fireworks.
----
* AllPeriodsArePMS: She's the ''only'' female NPC that averts this during the Blood Moon.
* GenkiGirl: Just like the pony she's based off, most of the thoughts running through her mind are about fun and parties.
* ImprobableWeaponUser: Uses [[AbnormalAmmo Confetti Guns]] and [[GrenadeSpam Happy Grenades]] in self-defense.
* JokeItem: All of her items have no real significance for actual combat or other tasks but just there to, well, party.
* LethalJokeItem: The Fireworks she sells in Hardmode can ''kill'' enemies and even bosses, and the Confetti she sells can be combined with empty casings from the Arms Dealer to make Confetti Ammunition, which is more powerful than all pre-Hard Mode ammunition.
* ShoutOut: She is a ''very'' blatant shout out to [[{{WesternAnimation/MyLittlePonyFriendshipIsMagic}} Pinkie Pie]], she has blue eyes, dark pink hair, a love for parties, etc. And she can have names such as Sparkle and Trixie.

[[/folder]]

[[folder:Dryad]]
A nature spirit will move in if you have defeated at least one Pre-Hardmode boss, with several exceptions such as King Slime or the Wall of Flesh. She can tell how corrupt/crimson or hallow the world is and sells various natural materials like acorns and seeds.
----
* AllPeriodsArePMS: During the blood moon but not as bad as the Nurse and Mechanic.
* GardenGarment: She's clad in naught but vines and leaves. Players can buy it during Halloween and wear it themselves.
* GreenThumb: Nearly everything she sells has something to do with growing vegetation or altering nature. When monsters are nearby, she'll cast a barrier of leaves that buffs up the defense nearby players and [=NPCs=], increases their life regen, and gives them the [[CounterAttack Thorns]] ability. The more bosses you defeat, the more powerful the barrier gets against enemies.
* MsFanservice: Not entirely visible in game, but definitely in most fanart.
* NatureSpirit
* NiceGirl: She's one of the kinder NPC[=s=] in the game ([[AllPeriodsArePMS when it's not a Blood Moon]]), passionate about the wellbeing of her neighbors and the environment and one of the few people who is on good terms with the Truffle.
* OurFairiesAreDifferent: Being a dryad, she's a fey creature associated with plantlife and happens to be one of the few fairies in the game who has a humanoid shape.
* Really700YearsOld: "I wish [Arms Dealer] would stop flirting with me. Doesn't he realize I'm 500 years old?"
* ShoutOut: "The sands of time are flowing, [[PrinceOfPersia and you are not aging gracefully]]."
* {{Stripperiffic}}: Those vines don't cover a lot of skin.
* WellIntentionedExtremist: She encourages the player character to make the world a CrapsaccharineWorld by spreading the Hallow, although as of 1.3 she'll praise the player even more for completely purifying the world.
* YouGottaHaveBlueHair: Her hair is grass green and done up in a long, curling braid.
[[/folder]]

[[folder:Arms Dealer]]
He moves in after you find a gun. He sells guns and bullets.
----
* ArmsDealer: Of the Gun Shop Owner type. He can sell you illegal parts, however.
* BloodKnight: He loves the sheer amount of enemies he has the chance to kill during Blood Moons. After all, it's much more fun that trying to hold a conversation with his neighbors while the event lends most of them their own JerkassBall.
* CasanovaWannabe: He has a tendency to flirt with the ladies. The Dryad is sick of him doing so with her due to the massive age difference, the Mechanic already has a crush on the Goblin Tinkerer and is completely oblivious to his innuendo-laden jokes, and he may occasionally mention that he's preparing for a date with the Nurse or say that he's into what she's selling.
* CovertPervert: If the Halloween event is any indication, he's not above having spare of the Nurse's clothes lying around and selling them.
* DoubleEntendre: He may mention that he "wants what the Nurse is selling" and the Mechanic may mention that he's asked her if he could press her pressure plates.
* The Gunslinger: Wields either a Musket pre hardmode, or a [[MoreDakka MiniShark post hardmode]]
* KineticWeaponsAreJustBetter: Notice how he only sells weapons and ammo that are kinetic?
* MoreDakka: The guy loves his firearms. He also sells the infamous Minishark, which can then be upgraded into the extremely fast-firing Megashark.
* TheRival: To the Demolitionist.
* ShotgunsAreJustBetter: He sells them in hardmode.
* YouDoNOTWantToKnow: It's best he didn't answer HOW he made the Minishark, even stating this trope's name in a conversation with the player.
[[/folder]]

----
* AllYourPowersCombined: Sells a workbench that allows you to combine certain sets of accessories together.

* GrapplingHookPistol: Sold for 2 gold in case the RandomlyDrops were unkind that you couldn't find an actual hook for one.
* InterspeciesRomance: He and the Mechanic have a mutual crush on each other.
* {{Jetpack}}: Sells Rocket Boots for 5 gold, and combined with Hermes Boots at the workbench to make Spectre Boots.
* LampshadeHanging: He hangs a lot of lampshades on the goblins such as the fact that they carry the spike balls they drop, the true direction they approach from due to the sun's left-to-right pattern (making West and East flipped), the fact that thieves don't even steal anything and that tattered cloth from their scouts can be used to start a war with them.
* LuckBasedMission: Getting the right modifier for a weapon can cost immense amounts of time and money, especially if said item is incredibly expensive to buy/sell. But that Unreal Megashark is so tempting...
* OurGoblinsAreDifferent: He's quite adept at technology, selling you the tinkerer's workshop, necessary to combine accesories, and also sells spike balls that can be used as traps.
* ShipTease: He's always asking about the mechanic.

** "Hey, does your hat need a motor? [[Music/{{Motorhead}} I think I have a motor that would fit exactly in that hat]]."
** "[[http://knowyourmeme.com/memes/xzibit-yo-dawg Yo, I heard you like]] [[http://terraria.gamepedia.com/Rocket_boots rockets and]] [[http://terraria.gamepedia.com/Hermes_Boots running boots]], [[http://terraria.gamepedia.com/Spectre_Boots so I put some rockets in your running boots]]."

[[/folder]]

[[folder:Witch Doctor]]
The witch doctor moves in after defeating the Queen Bee. She/He sells the imbuing station and various tribal-themed accessories and items.
----
* AmbiguousGender: None of the NPC[=s=]' conversations mention his gender at all and his mask obscures his facial features. The only way one can find out on their own is to mess around with King and Queen Statues and wait for the King to teleport him.
* AmbiguouslyHuman: He may or may not be a [[LizardFolk Lihzahrd]].
* BlowGun: His WeaponOfChoice.
* WitchDoctor

* ShoutOut: Nearly every line he says is a reference to a Creator/TomHanks movie.
* SpellBook: Uses the Book of Skulls to attack monsters.

* InterspeciesRomance: She's a human, and has a crush on the Goblin Tinkerer.
* ObliviousToLove: She doesn't understand the Arms Dealer's comments about "pushing her pressure plate". On the other hand, she appears to have a mutual crush on the Goblin Tinkerer.
* ShipTease: She's always asking about the goblin tinkerer.
* WillTheyOrWontThey: Towards the Tinkerer.

[[/folder]]

[[folder:Pirate]]
The pirate moves in after defeating the Pirate Invasion and sells cannons primarily, and some other things.
----
* AbnormalAmmo: Fights with a Coin Gun.
* PirateParrot: Which you can buy as a pet, but it requires him in the ocean and is the most expensive item in the entire game. The Cyborg also implies the Pirate has one of his own after exclaiming how corrosive it's droppings are to him.
* TalkLikeAPirate: His manner of speaking.
[[/folder]]

[[folder:Santa Claus]]
He will only move in if 1: [[HolidayMode It's around December 15th to 31st]] and 2: If you summon, and defeat the Frost Legion. He sells a variety of Christmas-themed decoarative items, including christmas trees and trimmings.

* DemBones: He's a skeleton, albeit a friendly one.
* GloveSlap: During a Hardmode Blood Moon, he carries a glove on a stick, while it's damage and critical chance is mediocre at best, it has the single highest base knockback of any weapon beyond the [[{{BFS}} Breaker Blade]] and is great for repelling enemies not entirely immune to knockback.
* KillerYoYo: He can sell the various yo-yo counterweights that send out a tiny, orbiting counterweight upon attacking an enemy and during Hardmode, he not only can sell two unique yo-yos but also the yo-yo glove that allows the equivalent of DualWielding two of the same yo-yo at once.

[[/folder]]

! Bosses

[[folder:The Eye of Cthulhu]]
First boss of the game, it can appear if you craft/find and use a suspicious looking eye during the night, or if you expand you maximum health over 200, it has 2800 health and the first phase involves [[FlunkyBoss spawning tinier versions of it]], after its health goes down to 1400, it will transform into its second phase, the lens turning into a gaping maw as it rams you much more often but it does lose a bit of defense from it. On death, it will drop gold, potions, demonite ore/crimtane ore (depending if it's corruption/crimson in the world respectively) and several hearts to refill your life along with a chance for it to drop binoculars and it's respective boss trophy and mask. On Expert, it drops a Treasure Bag that may contain the above items, as well as a Shield Of Cthulhu, that gives a bit of defense and also allows the player to perform an [[InvulnerableAttack invulnerable]] ShieldBash.
----
* EldritchAbomination: Well, at least the eye of one.
* FlunkyBoss: For the first phase.
* GiantEyeOfDoom: The first major Lovecraftian horror most players with find themselves against, and once it loses enough health it ditches its iris for a horrifying and toothy mouth. With its speedy charge, it can easily outmatch an unprepared player.
* TimeLimitBoss: It will run away if you do not defeat it by dawn.
* TurnsRed: The 1.3 Big Update adds a new attack to the Eye's arsenal in Expert Mode, granting it a powerful and even faster berserker charge when it is critically wounded.
[[/folder]]

[[folder:The Eater of Worlds]]
A giant worm and the second boss of the game that will show up when you smash three shadow orbs in succession or craft and use worm food. It is a giant version of the devourer and each section can have 65/150/220 health if it is the head/body/tail respectively. When a section of it is killed, it will [[AsteroidsMonster split into multiple worms]], more-so the more you split it, so it's best to attack the head. Every section also drops demonite ore and shadow scales, while killing the last section will net you some potions along with a chance of dropping an Eater's Bone (summons a baby Eater of Souls as a pet) and it's respective boss trophy and mask. On Expert, it drops a Treasure Bag that may contain the above items, as well as a Worm Scarf, which [[DamageReduction reduces all damage taken by 17%]].
----
* AsteroidsMonster: You attack any segment that isn't the head, it will split up into two separate worms, and ditto with those until the whole creature is destroyed.
* SandWorm: Well, Corruption Worm. Plays this straight if summoned in a corrupted desert.
* SegmentedSerpent: Destroying the wrong segments (read: anything that isn't the head) will cause it to split!
[[/folder]]

[[folder:Brain of Cthulhu]]
One of the new bosses in the crimson biome of the 1.2 update and has 1000 health. It first attacks by [[{{FlunkyBoss}} releasing eyeball-like minions called Creepers]] against you and cannot be harmed until all of them have been killed.

Defeating it rewards you with Crimtane Ore and tissue samples that are used to make items similar in quality to the Demonite weapons and armor. It also has a chance to drop a Bone Rattle (summons a baby Face Monster as a pet) as well as a trophy and mask. On Expert, it drops a Treasure Bag that may contain the above items, as well as a Brain of Confusion that confuses enemies when the player is struck.
----
* DoppelgangerSpin: On Expert, during the second half of the fight. Each time it teleports, it produces three translucent, harmless fake images of itself that also converge on you. As its health gets lower, these images become less transparent, making it harder to distinguish the real one.
* EldritchAbomination: Again, at least the brain of one.
* FlunkyBoss: Much like the Eye of Cthulhu, it summons eyeball-like minions to attack you. Unlike the Eye of Cthulhu, these ''must'' be destroyed if you want to hurt the Brain itself.
* StandardStatusEffects: On Expert, any CollisionDamage with the eyeballs or the Brain can cause the Confused, Poison, Bleeding, Darkness, Broken Armor, or Weak status effects.
* SuspiciouslySimilarSubstitute: Due to being a floating brain-like enemy that attacks you with eyeball-like minions, the Brain of Cthulhu is possibly the closest thing the PC version has to Ocram.
* TeleportSpam: In the second half of the fight.

[[folder:King Slime]]
The king slime will appear when the player is 2/3 from the center of the map, on a chance of 1 in 300, if the player crafts and uses a slime crown or after defeating a certain amount of slimes during a Slime Rain. It has 2000 health and will shrink as it's attacked, [[AsteroidsMonster spawning smaller blue slimes]] as it does so. Upon defeat, it will drop a single gold coin and one of three pieces of the ninja clothing and a chance to drop the Slime Hook, Slime Gun, a Slimy Saddle that summons a slime mount and it's respective trophy and mask. On Expert, it drops a Treasure Bag that may contain the above items, as well as a Royal Gel, which makes slimes friendly towards the player if equipped.
----
* AndYourRewardIsClothes: You beat it? Enjoy your random part of the ninja costume and possibly the boss mask. Not so bad since 1.2.4 as it now drops the Slime Hook, the Slime Gun and a Slimy Saddle that you can get a Slime mount. And then 1.3 improves the drops even more by making the Ninja costume into functional armor that improves Throwing weapons.
* AsteroidsMonster: It will eschew normal slimes from itself as it takes damage.
* CoolCrown: Now wears one after the 1.3 update, making it look very similar to King Slime from ''Franchise/DragonQuest''.
* FlunkyBoss: Spawns blue slimes as it takes damage. On Expert, it can also spawn ''spiked'' blue slimes.
* KingMook: Basically a bigger, stronger version of the blue Slime. After the 1.3 update he even has a crown, and also appears as the boss of a Slime Rain.
* ShoutOut: To NinjaGaiden with the ninja floating inside it, being a reference to a boss of the same one you fight.
* ShowsDamage: It gets smaller as its health gets lower. Justified as it starts losing mass as it takes damage, as shown by the blue slimes it releases when taking enough damage.
* SpikeShooter: Not King Slime itself, but the Spiked Blue Slimes it spawns on Expert can fire spikes at the player.
* {{Teleportation}}: Will now dissolve and reform on the player if it happens to get stuck, so it cannot be trapped anymore.

[[folder:Queen Bee]]
One of the new bosses that can be found in the randomly generated beehives in the underground jungle and summoned by either breaking an object within a hive or crafting and using an [[{{Pun}} Abeemination]]. She has 3400 health and attacks by ramming, shooting stingers at you and [[{{FlunkyBoss}} summoning smaller bees]]. On defeat, she can drop the [[{{BeeBeeGun}} Bee Gun]], the Bees Knees (a bow that shoots Bees), the hive wand (places down hive blocks), part of the bee vanity set, a nectar to summon a hornet pet, the Honeyed Goggles (to summon a Bee Mount) the Bee Keeper (A bee themed sword), the Honeycomb (summons bees when hit) and her trophy and mask. On Expert, she drops a Treasure Bag that may contain the above items, as well as a Hive Pack, which makes bees spawned by the player have a chance to come out as a larger, faster, more damaging version.
----
* BeeAfraid: You stumble into a hive, with not many monsters inside unless you start digging into the walls. Then you attack the Larva... and a gigantic bee attacks you furiously in retaliation.
* BeeBeeGun: Can send out smaller bees to attack you.
* BewareMyStingerTail: Like the Hornets, she can fire out venomous stingers that poison the player.
* BigCreepyCrawlies: The largest insectoid enemy in the game[[note]]Destroyer doesn't count as it's a worm[[/note]].
* BerserkButton: Killing the Bee Larva in any of the bee hives will summon her.
* KingMook: A ''Queen'' Mook towards the Hornet enemies.
* MamaBear: Kill her larva and she'll awaken and attack you in retaliation.
* RammingAlwaysWorks: One of her attacks. She's able to fire out bees and stingers, but will also charge the player.
* SpamAttack: In Expert, she gets faster and faster with her attacks as she nears death, causing her to charge often, spawn bees often as well as fire stingers like a machine gun.
* StandardStatusEffects: Can poison you with her stingers.
* TurnsRed: Only on Expert. Her attack pattern gets faster and more frequent as she loses health.
[[/folder]]

[[folder:Skeletron]]
A giant floating skull and arms that is summoned by talking to the old man at the entrance of a dungeon at night, and the final boss of the initial releases before the 1.1 update. It has 4400 health on its head, while its arms/hands have 600 each. Its attack pattern consists of swinging its hands at you before spinning its head in your direction, lowering its defense while doing extra damage. Upon death, it will drop 5 gold coins and some potions with a chance to drop the Skeletron mask, the skeletron hand (works like a grappling hook), a Book of Skulls (a spell tome), it's boss trophy and it will grant you access to the dungeon and allow the clothier to move into your home. On Expert, he drops a Treasure Bag that may contain the above items, as well as a Bone Glove that upgrades thrown Bones while also giving a 33% chance of not consuming them. After being defeated for the first time, Skeletron can be fought again if a player equips a Clothier Voodoo Doll and kills the Clothier during night.
----
* CognizantLimbs: Both his hands. In Expert, you're required to destroy them, otherwise his head has exceptionally high defense.
* CycleOfHurting: On Expert, his spinning move upgrades once both arms are destroyed, being able to outpace and stick on your character for continuous, huge CollisionDamage.
* DemBones: It's a floating skull with disembodied skeletal arms.
* EverythingsBetterWithSpinning: For the player, anyway. His defense drops when his head is spinning.
* HomingProjectile: In Expert, he fires homing skulls ala the Book of Skulls once you've killed off one of his hands.
* SkippableBoss: Very strongly averted. Try to skip Skeletron and you'll be killed by the Dungeon Guardian, a NighInvulnerable BeefGate meant to punish such an attempted bypass. Even if you decide not to enter the dungeon at all, he is still required to be defeated if you want the cultists to appear and trigger the Lunar Events.
* TimeLimitBoss: It will ''kill you'' if you do not defeat it by dawn.
* TurnsRed: At dawn, it transforms into the [[BeefGate Dungeon Guardian]] and will OneHitKill you. In Expert, once his hands are destroyed, he begins firing skulls at the player while also upgrading his spinning attack to perform a CycleOfHurting.
[[/folder]]

[[folder:Dungeon Guardian]]
A special version of Skeletron meant to keep you out of the dungeon until you've defeated Skeletron proper, introduced to fix a loophole in which the Skeletron Heads that once held its role could accidentally grant access to the dungeon if killed. Delving too deep will summon this nigh-invincible horror, and thusly, [[OneHitKill your doom]].
----
* BeefGate: It's intended to keep you out of the dungeon until you've earned it by defeating Skeletron. Unlike most Beef Gates, however, this one will keep spawning if you try to enter the dungeon, no matter how many times you kill it.
* BraggingRightsReward: The [[http://terraria.gamepedia.com/Bone_Key Bone Key]] it drops when killed, which summons a mini-Skeletron pet.
* DemBones: A flying skull.
* DoppelgangerAttack: Sometimes two will spawn. Death is pretty much assured when this happens.
* EverythingsBetterWithSpinning: Constantly in this state.
* ForMassiveDamage: Does 1000 damage on contact, double the max life a player can possess, and impossible to tank without a specific set of gear.
* TheJuggernaut: Doesn't stop homing in on you, takes ScratchDamage from everything, {{One Hit Kill}}s you, and is practically invulnerable to {{knockback}}.
* LightningBruiser: It can fly faster than anything short of the best mount in the game, and can OneHitKill an endgame melee tank build on contact.
* LostForever: Vanishes once Skeletron is defeated, so get your Bone Key before you open the dungeon.
* NighInvulnerable: It has [[DamageSpongeBoss 9999 HP]] (which is doubled in Expert Mode), [[MadeOfIron 9999 Defense]] (turning all attacks into ScratchDamage), and is ImmuneToFlinching. It can be killed, but only with a ''lot'' of preparation.
* OneHitKill: Its sole purpose of existence. If it catches you, you're dead.
* RammingAlwaysWorks: It will crash into you at high speed and make you explode into gibs on impact.
* SelfImposedChallenge: Killing it is considered a personal achievement by Terraria veterans. The devs have acknowledged this, and it now drops the aforementioned Bone Key as a reward.
[[/folder]]

[[folder:Wall of Flesh]]
The final pre-hardmode boss, the Wall of Flesh is summoned by tossing a guide voodoo doll into lava in the underworld. As its name implies, it's a giant wall of flesh with two eyes and a mouth that [[AdvancingBossofDoom advances on the player]], shooting EyeBeams, [[FlunkyBoss barfing out leaches, and having "the hungry" attached to it]]. It also has a shared health of 8000. Upon defeat, the drops are spawned in a box of demonite brick with a nice sum of money, a [[LeetLingo Pwnhammer]], and one of the six rewards ranging from a warrior/ranger/sorcerer emblem, a [[FrickinLaserBeams Laser Rifle]], a Clockwork Assault Rifle, or a [[VideoGame/FinalFantasyVII Breaker]] [[{{BFS}} Blade]] along with it's respective boss trophy and mask. On Expert, it drops a Treasure Bag that may contain the above items, as well as a Demon Heart, which permanently increases your accessory slots to 6, but only on Expert Mode worlds. Its death also triggers the spawning of two massive veins of hallow and corruption/crimson as the world goes into hard mode.
----
* AdvancingBossOfDoom: It will charge at you and pursue you from one end of the world to another, there is no way to get past it, and if it is still alive by the time it is on the other end, it will crush you to death.
* BeefGate: The Wall of Flesh will easily kill the under-prepared, to prevent them from unleashing hardmode prematurely.
* DiscOneFinalBoss The most powerful pre-hardmode boss you face before you go into hardmode
* EyeBeams: It fires volleys of purple lasers at you from it's eyes, and the time between shots decreases as it's health gets lower until it's full-on BeamSpam.
* EldritchAbomination: Moreso than the other pre-hardmode bosses because it can inflict a MindRape on you that forces you to kill it to survive. According to a card, it's the lord of eternal nightmares,
* FlunkyBoss: This game loves these bosses a lot.
* GoForTheEye: While both its mouth and eyes are vulnerable, the eyes have zero defence and thus do not benefit from any DamageReduction, making them the preferred targets.
* LivingStructureMonster: The Wall of Flesh is ExactlyWhatItSaysOnTheTin - a massive, moving wall with eyes and a mouth.
* LoadBearingBoss: Its death infects the world with large swathes of ever-expanding hallow and corruption.
* NintendoHard: Either you're over-prepared or you die. There is no middle ground.
* TimeLimitBoss: You have to defeat it before it reaches the other side of the world and kills you.
* TurnsRed: As you wear down its health, it will start gaining speed, belch up leeches more often and will shoot its EyeBeams more often.
* YouWillNotEvadeMe: The wall will use its tongue to reel you in if you run to far from it, get behind it or try to escape the underworld conventionally. Trying to use the magic mirror to escape splatters you when you reach your spawn. This isn't as bad as it sounds for soft-core or even medium-core characters as your money/items drop at the spawn/bed that you warped to. [[{{FinalDeath}} Hard-core]] however...

[[folder:The Destroyer]]
Possibly the first of the hard mode bosses you face, it's a mechanical version of the Eater of Worlds. It has 80000 health and is summoned by crafting and using a mechanical worm during the night. Like the Eater of Worlds, it burrows through the ground and attacks by ramming, and also by firing lasers from its sections. It will deploy probes from its sections to attack the player. Upon defeat, it drops 12 gold, greater healing potions, Souls of Might and hallowed bars along with it's boss trophy and mask. On Expert, it drops a Treasure Bag that may contain the above items, as well as a Mechanical Wagon Piece used to craft the Mechanical Minecart. Which is not only the fastest minecart but the fastest transportation method surpassing asphalt.
----
%%* AnimalMecha
* AttackDrone: Sends these out.
* BeamSpam: Both its sections and probes can do this from time to time.
* BossArenaRecovery: Destroying the probes it sends out will get at least one heart and/or a mana star if you've been using magic weapons.
* FlunkyBoss: The probes it sends out upon being hurt.
* FrickinLaserBeams: The aformentioned probes will start letting out a barrage of lasers should they be allowed to survive for a bit,
* MarathonBoss: Has more HP than any other non-composite entity opponent in the game, but averted if the player has a weapon with a large area of effect and/or hits multiple times. Each of The Destroyer's segments is an individual hitbox, so one piercing projectile can hit The Destroyer ten times. If someone has already defeated The Twins and has used their souls of sight to build a Magical Harp[[note]]fires slow, infinitely piercing projectiles rapidly as long as your mana meter holds out[[/note]] weapon, the boss fight becomes nearly effortless.
* SegmentedSerpent: Good christ, with hundreds of segments this thing is ''massive''. The player can attack multiple segments at one go, allowing them to deplete its massive HP faster.
* TimeLimitBoss: Runs away at dawn.
[[/folder]]

[[folder:The Twins]]
A mechanical version of the Eye of Cthulhu, [[DualBoss except there are two of them]], [[EyeBeams Retinazer]] and Spazmatism. They're summoned by crafting and using a mechanical eye at night, they have 24000 health each, and each attack the player: Retinazer by firing lasers and occasionally ramming, Spazmatism by firing cursed flames and also occasionally ramming. When down to 12000, Retinazer transforms into a mechanical eye with a larger laser cannon in place of its lens, firing lasers and spamming occasionally. Spamatism transforms into a mechanical maw, firing a stream of cursed flame and ramming at the player like the [=EoC=] on crack. Upon the defeat of the two, they drop 12 gold, greater healing potions, Souls of Sight and hallowed bars and either of them can drop their boss trophies and masks. On Expert, it drops a Treasure Bag that may contain the above items, as well as a Mechanical Wheel Piece used to craft the Mechanical Minecart. Which is not only the fastest minecart but the fastest transportation method surpassing asphalt.
----
* BreathWeapon: Spazmatism will spew a constant stream of Cursed Flames in his second phase.
* BeamSpam: The lower Retinazer's health is in the second phase, the more it does so.
* DegradedBoss: In a rare beneficial version! Players can craft an staff that lets them summon miniature stage two Twins to aid them in battle and they keep their signature breath and laser attacks. A properly geared player can have a pack of ''18'' of these things trailing behind them.
* DualBoss: The only one in the game, for some reason.
* EyeBeams: Retinazer, Retinazer, Retinazer. It gets worse the lowers it's health gets.
* GiantEyeOfDoom: Two of them this time.
* {{Hellfire}}: Used by Spazmatism.
* ShortRangeGuyLongRangeGuy: Apparent in their second forms- Spazmatism is the Short Range, attempting to stay close to breathe cursed flames and charge the player, while Retinazer is the Long Range, attempting to stay far while firing lasers at the player.
* TimeLimitBoss: The two will run away at dawn.
* TurnsRed: Their second forms, but Retinazer has a particularly noteworthy one; the lower its health gets during its second phase, the faster it fires the laser cannon, especially in its BeamSpam.
[[/folder]]

[[folder:Skeletron Prime]]
The mechanical version of [[CaptainObvious Skeletron]]. Summoned by crafting and using a mechanical skull at night, it has a max life of 30000 on the head and attacks the player by swinging its vice or saw arm, shooting at the player with the laser arm, or bombing the player with its cannon arm. Unlike Skeletron, who loses defense when spinning, Prime ''gains'' defense when spinning. Compared to the other two hard mode bosses, Prime is the hardest of the three and usually requires teamwork (or bug exploitation) to defeat. When destroyed, it drops 12 gold, greater healing potions, Souls of Fright and hallowed bars along with a chance to drop it's boss trophy and mask. On Expert, it drops a Treasure Bag that may contain the above items, as well as a Mechanical Battery Piece used to craft the Mechanical Minecart. Which is not only the fastest minecart but the fastest transportation method surpassing asphalt.
----
* ChainsawGood: The Prime Saw arm.
* CognizantLimbs: Has four destructible limbs, each carrying a deadly weapon of their own.
* DemBones: Mechanical ones this time.
* EverythingsBetterWithSpinning: Unlike Skeletron, Prime benefits from spinning as his defense actually ''increases'' instead of decreasing when he does so.
* FrickinLaserBeams: The Prime Laser arm.
* MultiArmedAndDangerous: Has four arms as compared to Skeletron's two, and each arm has a different weapon to murder you with on each end.
* PowerPincers: The Prime Vice arm.
* ThrowDownTheBomblet: The Prime Cannon arm.
* TimeLimitBoss: Like Skeletron, Prime has a Dungeon Guardian form and will kill you at dawn.
[[/folder]]

[[folder:Ocram]]

The true final boss, found only in the console versions of Terraria. He has 35000 max health and is summoned by using the item called the Suspicious Looking Skull, and is the hardest boss in the game. Ocram can best be described as a flying ''Film/{{Predator}}'' head. On death, he drops Souls of Blight and Adamantite Ore, along with a chance of dropping pieces of the console-specific new armor sets.
----
* BeamSpam: Its first form loves this.
* BulletHell: Not only does it do this itself, but this is also the focus of most strategies for fighting him.
* CallBack: Oddly enough, to the Eye of Cthulhu. His strategy is similar, his flunkies are called "Servants of Ocram" like the Eye's "Servants of Cthulhu", and they share a battle theme.
* EldritchAbomination: Quite.
* FinalBoss: Confirmed to be as such by the (console version's) [[WordOfGod developers.]]
* FlunkyBoss: Sends out Servants of Ocram, though he has plenty of other attacks. They're fairly easy to kill if you use Crystal Bullets. However, don't mistake him for relying solely upon them.
* GiantSpaceFleaFromNowhere: Has no buildup or references, not even in the item used to summon him. He's also the only non-robotic Hardmode boss.
* LightningBruiser: He moves fast and hits HARD.
* NintendoHard: He's pretty much impossible to kill without near-endgame to endgame armor.
* OmnicidalManiac: If you summon it too close to your house/town, it can and will kill your [=NPCs=].
* TurnsRed: His second form turns out his eyes, reveals a bigger eye, and also amps up the power of his BeamSpam attack.
[[/folder]]

[[folder:Plantera]]
A new boss of the jungle biome during hardmode. It has 30000 health and is encountered by destroying the glowing pink plants you find and it chases after you by grappling onto the walls. The fight first starts off with it shooting poisonous stingers at you and when down to half health, the petal will split into a maw while having several of it's flunky plants sprout out. On defeat, Plantera will drop the temple key that unlocks the door to the Lihzarhd temple along with other items that have a chance of dropping such as the seedling (summons a seedling pet), The Axe (a guitar themed hammeraxe), the Pygmy Staff (allows you to summon Pygmies), a GrenadeLauncher and the respective rocket ammo, the [[{{HandCannon}} Venus Magnum]], the Nettle Burst (a supped up Vilethorn), A Leaf Blower, a [[{{EpicFlail}} Flower Pow]], the [[{{BeeBeeGun}} Wasp Gun]] and its respective trophy and mask like the rest of the bosses now have. On Expert, it drops a Treasure Bag that may contain the above items, as well as a Spore Sac, which allows the player to generate damaging homing spores over time.
----
* CombatTentacles: Its invulnerable grappling hooks can deal damage, and it sprouts a bunch of smaller, destructible ones when it TurnsRed. In Expert Mode, his grappling hooks sprout them too when it TurnsRed!
* BerserkButton: If you lure it out of the Underground Jungle biome, it will become more aggressive and damaging.
* FlunkyBoss: The plants that it sprouts when it TurnsRed.
* ManEatingPlant: Even more so than the Man Eaters you used to encounter in the jungle.
* {{Pun}}: Of the band ''{{Pantera}}'', especially so because of its unique boss theme.
* SpikeBallsOfDoom: Spits these out in its first phase.
* SpikeShooter: First phase uses these.
* TurnsRed: At half health, the flower will drop off, sprout tentacle plants, and it'll become much faster and damaging.
[[/folder]]

[[folder:Golem]]
The boss of the Lihzarhd temple by using Lihzarhd Power Cells at the temple's altar. The fight starts with the Golem shooting its chained fists (7000 health each) at you along with shooting fireballs and lasers from its head (16000 health). When the head is fully damaged, it flies into the air and you then have to attack its previously invulnerable body (9000 health) while avoiding the floating head's attacks. On defeat, it can drop a Stynger, a Possessed Hatchet, a [[{{PowerOfTheSun}} Sun Stone]], the Eye of Golem, a Picksaw, a Heat Ray, a Staff of the Earth, one of it's fists, and it's respective trophy and mask. On Expert, it drops a Treasure Bag that may contain the above items, as well as a Shiny Stone that greatly increases the rate of a player's RegeneratingHealth if they are not moving or attacking/mining.
----
* CognizantLimbs: His arms can be attacked and destroyed separately.
* EyeBeams: The first phase uses these when its health gets low. The head in the second phase also uses them.
* {{Fireballs}}: Spits out bouncing ones.
* FrickinLaserBeams: The EyeBeams it fires are slower than light.
* {{Golem}}: It's a construct created by the Lihzarhd.
* HyperDestructiveBouncingBall: The fireballs the head shoots out.
* LosingYourHead: When he TurnsRed. Justified because he's a construct.
* PowerOfTheSun: Many of the Golem's drops are associated with daytime and the sun,
* OutsideTheBoxTactic:
** The Golem used to be unable descend wooden platforms, and it spawns by dropping down from the ceiling. Setting up a barrier can prevent you from having to take CollisionDamage entirely. This has been fixed as of 1.2.3.
** It's still one of two bosses unable to pass through solid blocks, allowing a player to trap him inside and attack him from there with a wall-piercing weapon.
* RocketPunch: His arms. The Golem Fist he drops allows the player to do the same.
* TurnsRed: Its head flies into the air and becomes invincible when its health is depleted, forcing you to attack its body directly.
[[/folder]]

[[folder:Duke Fishron]]
A giant fish-pig-dragon hybrid summoned by using a Truffle Worm as fish bait in the ocean. Duke Fishron has 50000 health, is extremely fast and will attempt to charge into the player a few times before either spewing a stream of homing bubbles, or dropping typhoon projectiles that spawn Sharknados- tornadoes that spew sharks. Once he TurnsRed, his eyes glow and his attacks become faster and deadlier. In Expert Mode, he has a new DesperationAttack where he shrouds the area in fog and uses a TeleportSpam combined with charging at you. On defeat, Duke Fishron can drop the [[EpicFlail Flairon]], the [[{{Multishot}} Tsunami]], the [[DeadlyDisc Razorblade Typhoon]] spell, the BubbleGun, the Tempest Staff (summon your very own Sharknado), his wings, and his respective trophy and mask. On Expert, it drops a Treasure Bag that may contain the above items, as well as a Shrimpy Truffle that allows the player to ride a Duke Fishron mount.
----
* AscendedMeme: Was originally supposed to be the boss of an AprilFoolsDay joke, the Tidal Moon event. While the event isn't real, Duke Fishron is.
* BerserkButton: If you lure him out of the Ocean biome, it will become more aggressive and damaging.
* BonusBoss: He's the only Hardmode boss that doesn't need to be beaten in order to fight [[spoiler: The Moon Lord]], and you need to go somewhat out of your way in order to summon him.
* BubbleGun: Spits homing bubbles at the player.
* ByTheLightsOfTheirEyes: His expert mode ability shrouds the entire area in fog while he turns invisible, and his glowing eyes is one way to detect him before he charges.
* DesperationAttack: He gains one when he's at very low health on Expert Mode. It involves him turning the screen dark while he turns invisible before he charges you.
* FlunkyBoss: Summons Sharknadoes and Cthulhunadoes that spew out flying shark projectiles called Sharkrons.
* FlyingSeafoodSpecial: He's a huge flying fish.
* GlowingEyesOfDoom: When he TurnsRed.
* HomingProjectile: His bubbles and his Cthulhunado typhoon.
* ImplacableMan: Got buffed in 1.3- he will ''repeatedly'' charge at you if you exit the ocean, instead of charging five times then attacking.
* KingMook: To both a Mook (Pigron) as well as a particular fishing catch (Fishron).
* LightningBruiser: Extremely fast, extremely painful, and sports 50000 health, more than most other bosses.
* MixAndMatchCritters: A fish-pig-dragon creature.
* NintendoHard: Deals painful damage with his attacks, moves extremely fast, and a lot of health to wear down. Speed-increasing items and Wings are pretty much mandatory if you don't want to be torn to shreds. In 1.3 and above, you're also constrained to fighting him within the ocean, or else he ''[[BerserkButton gets pissed]]''.
* RammingAlwaysWorks: Has a high tendency to ram the player.
* ShoutOut: Has the ability to summon Film/{{Sharknado}}es.
* TrademarkFavoriteFood: He can only be summoned via a Truffle Worm.
* TurnsRed: Gains GlowingEyesOfDoom, charges faster but less often, and changes his bubble spray into a spinning spray that creates more bubbles and his Sharknado into a Cthulhunado which is much larger, homes in on the player before deploying, and summons many more Sharkrons. The Fishron Mount obtained from him in Expert Mode allows the player to do this- when low on health, they gain an attack and speed buff.
* VictorGainsLosersPowers: When the player beats him, they get equipment based on his abilities: Flairon and Bubble Gun are based on his bubble spray, Tsunami is based off his relentless charges, Razorblade Typhoon is based off his Cthulhunado-spawning homing typhoons, the Tempest Staff is a smaller Sharknado, Fishron's Wings give the player the Duke's superior air and water mobility, and the Expert Mode Shrimpy Truffle nets the Duke himself as a mount, allowing ''you'' to [[TurnsRed Turn Red]] when low on health.
[[/folder]]

[[folder:Lunatic Cultist]]
After Golem is defeated, a group of cultists will gather outside the dungeon praying towards an ominous stone. Killing all of them incites the wrath of the Lunatic Cultist, who absorbs the power of the stone, and attacks you.
* ApocalypseCult: He's the leader of them.
* BigNo: He says this upon death.
* DoppelgangerAttack: Can make copies of himself that can fire at you. However, most of the copies cannot be destroyed.
* EvilSorceror: Very much so.
* EvilSoundsDeep: His voice sounds inhumanly deep as he prays to the stone in BlackSpeech before absorbing it and turning his attention to you.
* FireIceLightning: Can cast homing fireballs, ice crystals that fire ice spikes, and lightning bolts.
* InstantAwesomeJustAddDragons: He can create a circle that summons a huge phantasm dragon.
* InstantRunes: He will create a massive runic circle just before creating a doppelganger and attacking.
* MeaningfulName[=/=]PunnyName: He's lunatic in both senses of the word- crazy, and also moon-related.
* WithMyDyingBreathISummonYou: He summons the four Celestial Towers when defeated.
[[/folder]]

[[folder:The Celestial Towers (Vortex, Nebula, Solar, and Stardust Pillar) ]]
Four ominous pillars that appear after the Cultist Lord is beaten. These spawn powerful alien enemies, and must be defeated by killing enough of their minions to break the shield. Each of the pillars and their mooks correspond to a method of offence - Vortex for ranged, Nebula for magic, Stardust for summoner and Solar for melee.
* AmazingTechnicolorBattlefield: All of them turn the background to an ominous moon with coloured background when fought.
* EldritchAbomination: All four of the pillars are some kind of otherworldly aliens.
* FlunkyBoss: The pillars do attack, but mainly rely on spawning minions. It's also required that you beat enough minions first in order to attack the boss itself.
* MookMaker: Besides the bosses themselves, a number of the mooks can also spawn more mooks that will grow into even more Mook Makers if not removed in time.
* OurWormholesAreDifferent[=/=]SwirlyEnergyThingy: The Vortex Pillar creates these around the player, which spawn Alien Hornets.
* PlayingWithFire[=/=]ThePowerOfTheSun: The Solar Pillar's mooks are rather fiery and sun-like, and the pillar itself with attack with a shower of fireballs, many of which can be seen raining down in its background.
* StarPower: Of the Lovecraftian sort. The Stardust Pillar is able to create "stars" around it that spawn Star Cells and Milkyway Weavers.
* ShockAndAwe: The portals created by the Vortex Pillar can sometimes shoot a bolt of lightning at you, instead of spawning more {{Mooks}}.
* StationaryBoss: They don't move at all, and none of them apart from the Solar Pillar are directly capable of attacking you.
[[/folder]]

[[folder: The Moon Lord]]
The Lunar Event Boss - A large, Cthulhu-like being that is summoned after the four Celestial Towers are destroyed. His arrival is signified by a sense of impending doom, as the screen starts warping and turning black. As of the 1.3 update, he is the final boss of the game.
* AttackItsWeakPoint: The giant beating heart in his chest. The problem is that you must destroy all three of his eyes if you want him to expose it.
* BackgroundBoss: Stays in the background all the time. However, touching its eyes (or where they used to be) will deal CollisionDamage.
* BossVulnerability: Each of the targetable eyes are a Wait Them Out sort, while the heart is Always Vulnerable once it's exposed.
* CognizantLimbs: The eyeballs in his hands and his ThirdEye can attack separately and must be destroyed for him to expose his core.
* CthulhuMythos: Heavily resembles Cthulhu. His eyeball minions are even called "True Eye Of Cthulhu". WordOfGod has stated that he is Cthulhu's brother.
* DarknessEqualsDeath: He turns the background around him black, so if you lose track of him, a good way to find out where he's gone is the background rapidly growing darker as he slowly comes back.
* EldritchAbomination: An eldritch horror from the depths of space.
* EvilIsBigger: The largest enemy in the game as of now.
* EyesDoNotBelongThere: Has an eye in each of his hands.
* FinalBoss: Is this for the entire game.
* FlunkyBoss: When each eye is beaten, they will become an invincible flunky that attacks on its own.
* KaizoTrap: During his death animation, the holes where his weak points use to be will still hurt you, if you`re low enough on health, you`ll get killed and he`ll disappear without leaving behind any of his valuable drops or giving you the achievement for killing him.
* LifeDrain: Has an ability where his mouth sends out a sucker that starts draining balls of energy from you. If the balls are not destroyed before they reach his mouth, he regenerates health. During this, he'll inflict the Moon Bite debuff which also prevents you from lifestealing from him for the next fifteen seconds or so.
* MightyGlacier: The most powerful boss, and yet also one of the slowest.
* PowerFloats: Floats around the area effortlessly.
* NoSell: He's immune to lifestealing effects from the Spectre Armor and the Vampire Knives when he's leeching energy from you.
** As of 1.3.0.6, it's impossible to "cheese" him via using MercyInvincibility from other sources of damage- he will still hit you.
* NothingIsScarier: Before he appears, the background music ominously disappears.
* SequentialBoss: His three main eyes must be destroyed first, then his core will open.
* SuperPersistentPredator: Will chase the players across the map. 1.3.0.4 made it such that he just teleports right to you if you get too far from it.
* StrippedToTheBone: When beaten, its skeleton drops to the ground.
* WaveMotionGun: Can fire one of these from his ThirdEye. It sweeps around from one side of the screen to the other and does a great amount of damage, but is stopped by solid blocks. When an eye is detached, it can use a similar but weaker laser too.
* YouWillNotEvadeMe: The 1.3.0.4 update made it such that he teleports right to you if you get too far from him.

!! Enemies

%%[[folder:Goblin Scout]]
%%A semi-rare enemy that appears above 0 depth, during the day, around two-thirds away from the center of the map (the same area in which the King Slime can spawn). Scouts will not spawn on sand or in the corruption, nor will they appear among the other goblins during the goblin invasion.
%%----

%%[[/folder]]

[[/folder]]

%%[[folder:Undead Miner]]
%%A skeleton that appears underground, wearing a glowing mining helmet. When killed, it can drop bombs, a hook, or mining pants/shirt. They're easy to spot due to the glow of their helmets, and they can help illuminate undiscovered caverns.
%%----

%%[[/folder]]

----
* MadBomber: Its modus operandi.
* MonsterClown
[[/folder]]

[[folder:Tim]]
A skeleton sorcerer that can spawn underground. Like other casters, it will teleport around and fire projectiles until you kill it. When killed, Tim drops a wizard hat that can be used to increase magic damage or simply as a vanity item.
----
* MetalSlime
* ShoutOut: To ''Film/MontyPythonAndTheHolyGrail''.
[[/folder]]

[[folder:Ice Golem]]
The Ice Golem uncommonly appears in a Hardmode Ice biome during a blizzard. They can fire ice beams that slow the player for a very long time or even freeze. They have 4000 hp and drop the Frost Core, essential for crafting the Frost Armor, and may rarely drop the Ice Feather used to craft Frozen Wings.
----
* EyeBeams
* {{Golem}}
* AnIcePerson
* MightyGlacier
[[/folder]]

[[folder:Wyvern]]
The Wyvern sometimes appears in high altitudes in Hardmode. They zoom quickly across the screen and through tiles, and have 4000 HP and drop Souls of Flight, essential for the crafting of the games many wings.
----
* BossInMookClothing
* CallAPegasusAHippogriff / OurDragonsAreDifferent: Despite having the name of a variant of Western Dragon, the design of this one is more Eastern.
* InstantAwesomeJustAddDragons: The only ones in the game, not counting Arch-Wyverns in the console version and the Stardust Dragon.
* LightningBruiser
[[/folder]]

[[folder:Lost Girl/The Nymph]]
What appears to be an NPC named "Lost Girl", similar to the ones the player can rescue. Approaching her, however, has her transform into a green-skinned nymph that will maul unsuspecting players with potent melee attacks. When defeated, she has a 50% chance (100% in Expert Mode) of dropping a Metal Detector.
----
* BarbieDollAnatomy: She's depicted as fully naked, but lacks nipples or genitalia. Probably a display of modesty more than limitations of the art style.
* LuckBasedMission: She can drop a banner just like every other enemy. She's also one of the rarest spawns in the game. This does not affect her 0.5% chance to drop said banner
* HornyDevils: Mentioned above, she's naked and fairly attractive. Until she turns that is...
[[/folder]]

[[folder:Paladin]]
Appearing in the 1.2 Hardmode Dungeon, the Paladin is a heavily armored knight that throws giant hammers that pass through walls, cause a lot of damage and are very hard to avoid due to the dungeon's cramped spaces. They have 5000 HP.
----
* DropTheHammer: And they will sometimes drop from dead Paladins, and allow you to do the same thing.
* LightIsNotGood: It has really bright armor, and it starts not-so bright chaos.
* MightyGlacier: With its very high offences and defences, it can easily maim you in seconds while you struggle to kill it.
* SwordBeam: In the form of hammer projectiles.
[[/folder]]

[[folder:Rune Wizard]]
Appearing in the Hardmode Caverns, the Rune Wizard is an extremely rare enemy with one of the most powerful attacks in the game.
----
* GlassCannon: He can dish out some incredible pain, but he can't take a hit.
* NiceHat: You get his hat and robe if you kill him.
* TeleportSpam: Not to the extent of the dungeon mages, but he does warp around if you can't kill him quickly.
[[/folder]]

[[folder:Skeletons]]
You spend a lot of time battling skeletons in the game so here's a list of them: The first type of skeleton is found underground and drops hooks occasionally. Then, there's the undead miner (see above) and [[Film/MontyPythonAndTheHolyGrail Tim]] (also see above). Skeletron (see above) is fought to get into the dungeon. Once you get to the dungeon, you find angry bones that come in their normal size, along with [[GiantMook big boned]] and [[MiniMook small boned]] sizes. Also present are dark casters and then the cursed skulls (which can curse the player, rendering them unable to use items). In the underworld, you will find the bone serpent. On hard mode, the player fights armored skeletons and their heavy variants underground that poses a threat of breaking their armor (halved defense for five minutes) and skeleton archers that shoot flaming arrows at the player. And, finally, there is Skeletron Prime (once again, see above in bosses).
----
* DemBones: A whole collection of them, no less!
* StandardStatusEffects: Cursed (unable to use items) from the flying cursed skulls, broken armor (halved defense for 5 minutes) from armored/heavy skeletons, and fire from skeleton archers.
[[/folder]]

[[folder:Slimes]]
All slimes behave the same: They hop to get around and all but a few drop slime gel upon death. They come in all different colors and sizes such as green, blue, red, purple, yellow, black slimes that inflict darkness (reduced light vision), [[AsteroidsMonster mother slimes and their baby slimes]], [[MetalSlime Pinky]] (see above), [[UndergroundMonkey Jungle Slimes]], Dungeon Slimes that drop keys instead of gel, Lava Slimes that turn into lava in Expert Mode, and [[KingMook The Slime King]] (see above). In Hardmode, they are joined by the Toxic Sludge that can poison the player, [[AsteroidsMonster Corrupt slime and its slimelings]] that can also inflict darkness with a Shadow Slime variant in the Console version, the slimer that [[{{AirborneMook}} flies on bat wings]], and the glowing Illuminant slime that's found in the underground Hallow, above ground is the Rainbow Slime that can rarely spawn in rainstorms and drop rainbow bricks. The Crimson on the other hand will have Crimslimes that don't have the splitting or darkness inducing effect of Corrupted (or Shadow) slimes.
----
* BlobMonster: Naturally, given that they are gelatinous monsters.
* GlacierWaif: Pinky may be the smallest slime of the game, but it's only second to King Slime in terms of health when it comes to all of the slimes availabke before hardmode and it drops dozens of Pink Gel in contrast to its size.
* InformedAttribute: The gel they are made of is apparently rather tasty (particularly Pinky's), but it's impossible to it it raw without crafting it into a potion.
* KingMook: The King Slime.
* MetalSlime: Pinky, who drops a single gold coin and some Pink Gel but happens to have the highest health of any pre-hardmode slime. Rainbow Slimes count too; they show up very rarely in the Hallow during rainstorms while you are close to pure land, and drop the sought-after Rainbow Bricks.
* MoneySpider: Jungle Slimes, pre-hard mode. Most other enemies drop maybe one silver coin if they're high tier and you get lucky, while Jungle Slimes drop four or five silver coins as standard, aren't particularly hard to kill, and [[ZergRush spawn in droves]].
* RareRandomDrop: The Slime Staff has a 0.01% chance of being dropped by most slime variants. Hours upon hours upon hours can be spent trying to get the staff.
* StandardStatusEffects: Darkness (reduced light vision) and poison. The lava slime originally counted for fire since they turned into lava when killed before a patch removed that trait, until it was added in again as an Expert Mode trait.
[[/folder]]

[[folder: The Corruption]]
Once you start exploring TheCorruption, there are various, sickly looking, enemies, starting with the Eater of Souls: Small, flying enemies that swarm the player, along with [[{{GiantMook}} Big Eaters]] and [[{{MiniMook}} Little Eaters]], all three of which drop rotten chunks. There is also the Devourer [[{{SandWorm}} Worm]] that burrows through the ground, also dropping rotten chunks, along with worm teeth, used for unholy arrows. Then the king mook of the environment is the Eater of Worlds (see above in bosses). Bunnies and goldfish turn into corrupted versions of themselves during a blood moon. Once in hardmode, the aforementioned [[{{AsteroidsMonster}} Corrupt Slime and its slimelings]] spawn, along with the [[{{AirborneMook}} Slimer]]. Then there is the Corruptor, a flying enemy like the Eater of Souls but it can shoot vile spit that has a chance to weaken the player. If the corruption spreads to a desert, dark mummies will spawn, which drop dark shards by chance. Deeper down underground, World Feeders start to spawn, looking like the [=EoW=] mentioned above, that drop cursed flames when killed. Cursed hammers also roam the caves, and charge their target, having a chance to curse the player (unable to use items). Finally, there's the Clinger that acts like a plant enemy such as the man-eater, but it can spew cursed fireballs, flames that cannot be put out, even by water, meaning they also drop cursed flames when killed.
----
* AirborneMook: Eaters of Souls, Corruptors, and Slimers can fly around easily.
* TheCorruption: An evil, spreading biome that corrupts the land and turns critters into twisted, stronger versions of themselves.
* EliteMook: Corruptors, considering that they can appear much more often than other Hardmode corrupted creatures and have that little bonus of spreading the corruption with vile spit. Past 1.2 though, the corruption spreading bit has been taken out but they have a decent ranged attack and enough health to shrug off some attacks.
* FlyingWeapon: [[DropTheHammer The Cursed Hammer]]. A flying Hammer of course.
* GiantMook: Big Eaters, which are slightly stronger than the regular Eaters.
* MiniMook: Little Eaters, which are slightly weaker than the regular Eaters.
* StandardStatusEffects: Corrupt slimes and dark mummies inflict darkness, clingers inflict cursed inferno (water cannot put it out), corruptors inflict weakness (reduced stats) and cursed hammers inflict cursed.
[[/folder]]

[[folder: The Crimson]]
The Crimson biome appears as an alternative to the regular black Corruption, a land of rotting flesh and bodily fluids. Their lands resemble alien insect tunnels rather than the "impact craters" style of their counterparts. Their normal mode enemies include the Crimera, a floating cockroach-like expy of the Eater of Souls; Face Monsters, which are basically faster and tougher zombies; Blood Crawler, a giant ant which crawls along the walls to get you; and Blood Feeder, which are monstrous fish. Hard mode enemies include the Crimslime; the Floaty Gross; the Herpling and the Ichor Sticker.
----
* AnimalisticAbomination: Blood Crawler and Blood jellies.
* ArtisticLicenseBiology: The Blood Crawler drops vertebrae despite being based on an invertebrate. Could be a way to show that the eldritch nature of the Crimson that goes against nature itself.
* BigCreepyCrawlies: Blood Crawlers are basically huge ticks.
* BloodyMurder: Everything about these guys just screams eldritch flesh monsters. The Ichor Sticker shoots ichor at you, described as the blood of gods.
* BodyHorror: Face Monsters. Floaty Gross as well, if it's [[{{Buffy Speak}} name]] is any indication; considering that it rather looks like a [[{{Pokemon}} Gardevoir]] made out of bodily fluids, one could say it's pretty spot-on...
* CameBackWrong: The Floaty Gross is classified as an Undead enemy, and it has come back alright, and very ''[[HumanoidAbomination very]]'' [[BodyHorror wrong.]]
* TheCorruption: An alternative to the usual black-and-purple one.
* EvilIsVisceral: An evil place with a flesh, blood and gore theme.
* {{Expy}}: The Crimera to the Eater of Souls, Crimslime to Corrupted Slime, the Ichor Sticker to the Corruptor and the Crimson Axe to the Cursed Hammer.
* FlyingSeafoodSpecial: The Ichor Sticker is basically a flying squid.
* FlyingWeapon: [[AnAxeToGrind The Crimson Axe]]. A counterpart of the Cursed Hammer
* HumanoidAbomination: Face Monsters and to a lesser degree Floaty Grosses.
* LovecraftianSuperpower: The Ichor Stickers wear this on their sleeve.
* NightmareFace: There's a pretty good reason why the Face Monster is named that way.
* NoSell: Forget using Sunflowers to stop pre-hardmode Crimson, it will uproot them and take over the grass instead.
* ThemeNaming: Many of the Crimson creatures and related items begin with "Crim".
* StandardStatusEffects: Ichor Stickers inflict Ichor ([[DamageIncreasingDebuff lowers defence by 20]]), while the Floaty Gross inflicts Weakness.
[[/folder]]

[[folder: The Hallow]]
Once hardmode is activated, the hallow will start spreading as a bright, colorful environment with pearlstone, teal-colored grass, and rainbow-colored trees. This is also a straight example of LightIsNotGood, meaning that the inhabitants aren't merciful, such as violent pixies that deal heavy amounts of damage, along with a chance to slow you or silence you (unable to cast spells). Pixies drop dust when killed. Unicorns also roam around the hallow, and will charge you at high speed. They drop unicorn horns for the purpose of holy arrows and such. At night, there are also gastropods that can slow the player on contact, fire lasers at you from as far as off-screen, and drop gel upon death, like slimes do. Hallowed deserts contain a light equivalent of the dark mummies that drop light shards. Underground, there's the aforementioned illuminant slime as well as an illuminant bat. Chaos elementals that TeleportSpam to attack and avoid the player are also found here. Contrasting the underground corruption, there are enchanted swords that also attack the player and curse them.
----
* CrapsaccharineWorld: Bright, cheerful and healthy for the environment...and filled with vicious fairytale creatures.
* FlyingWeapon: [[{{BFS}} The Enchanted Sword]]. Unrelated to the equipable sword of the same name (In fact it looks like a glowing Excalibur). It's also the Hallowed version of the Crimson Axe and Cursed Hammer.
* FlyingSeafoodSpecial: Gastropods, if you consider them jellyfish.
* HeavenlyBlue: Hallowed grass becomes blue, and the Hallow in general is stated as having been overcome by the spirits of light. Additionally, there's also the Holy Water, a thrown weapon that spreads hallow upon impact.
* LightIsNotGood: Played painfully straight - despite the rainbows, pastel colors and flora-friendly atmosphere the biome is filled with creatures just as dangerous as the ones dwelling within the Corruption and Crimson. However, the Hallow does not force [=NPCs=] to move out unlike the Corruption and Crimson.
* LightningBruiser: Unicorns. Chaos elementals, considering that they can take about as much in damage, move as fast as the player and also TeleportSpam to close the distance even faster.
* StandardStatusEffects: Pixies inflict slowness (along with the gastropod) and silence, enchanted swords inflict cursed, light mummies inflict confusion.
%%* TeleportSpam: The Chaos Elementals.

!! Events
[[folder: Slime Rain]]

[[/folder]]

[[folder: Blood Moon]]
The Blood Moon has a 1 in 10 chance of occurring each night with a visible moon so long as a player with 120 health or more is in the world. Unlike other events, the Blood Moon incorporates biome specific monsters as well as their event specific monsters into the fray. In addition, certain harmless critters, such as rabbits and goldfish, turn hostile during the event, and will attack the player. Zombies and other monsters gain the ability to open doors, making them a much larger threat then they are usually.
[[/folder]]

[[folder: Goblin Army]]
Once the player has over 200 health and has defeated the Eater of Worlds, then the goblin army may invade at the start of a random day. Their numbers depend on how many players over 200 health are on the server and their force consists of weak peons that break down doors, fast thieves, slow but tough warriors, teleporting casters, and archers. On hardmode, powerful Shadowflame Summoners will appear as well. All of them drop spike balls and coins upon death and have a rare chance to drop a harpoon cannon. When the goblin army is defeated, the goblin tinkerer can be found underground to move into your home.
----
* AirborneMook: The Summoner can fly around to evade your attacks.
* BerserkButton: Apparently you can start a war with them using a flag made of tattered cloth. The Goblin Tinkerer mentions that they have quite the HairTriggerTemper.
* BossInMookClothing: The Goblin Summoner, who only appears in Hardmode, is much beefier than the rest of her army and summons homing projectiles on you.
* FragileSpeedster: Thieves.
* GlassCannon: Archers, they're not as fragile as the wizards but they are made short work of if you get close to them
* TheGoomba: Goblin Peons are the weakest and most expendable units, although they do have the ability to break down (not open like Blood Moon Zombies, ''break down'') doors.
* HitboxDissonance: Peons and Thieves have a smaller hitbox than their sprite, allowing them to squeeze through smaller areas.
* MightyGlacier: Goblin Warriors.
* SquishyWizard: Sorcerers--they're commonly offed with a single hit. Subverted with Summoners, who have much more health than the rest.
* TeleportSpam: Sorcerers, the Goblin Summoner takes this UpToEleven.
[[/folder]]

[[folder: Pirate Invasion]]
The pirate invasion can occur during Hardmode by a 6.22% chance at the start of any day or if the player uses a pirate map (dropped from enemies in the ocean) and approaches much like a goblin invasion. The force consists of Deckhands, Deadeyes, Corsairs, Crossbowers, Captains, Parrots, and the "boss", the Flying Dutchman. All pirates except the parrot has a chance of dropping the Cutlass, the Discount Card (20% discount while equipped), the Lucky Coin (damage can cause coins to drop) and the Coin Gun (shoots coins, the more damage the more value the coin is) along with the pirate banner. Any pirates excluding the captain and parrot can drop parts of the sailor costume, an eyepatch and golden furniture (that includes the table, chair, toilet, bed and door) and the parrots have a chance of dropping their respective banner. Defeating the Pirate Invasion allows a pirate to move into a house.
----
* AirborneMook: Parrots are fast flying enemies that deal large amounts of damage if they hit you.
* AuthorityEqualsAsskicking: The Captains are the toughest to deal with out of all the types of pirates.
* BossInMookClothing:
** Captains, immune to knockback (although constant DPS and DOT does keep them from attacking) and carry a rapid fire machine gun with a cannon strapped to it like an [[{{GrenadeLauncher}} M203]].
** The Flying Dutchman, a large flying pirate ship that rains cannonballs and drops pirate mooks into the fight. It has four high health cannons that must be taken down in order to be beaten.
* GuysSmashGirlsShoot: The Deckhands and Corsairs will attempt to charge the player, and while the Deadeye and Captain do use ranged weapons, they still attempt to move towards the player to deal collision damage. The female [[PirateGirl crossbower]] however stays in the back lines firing flaming arrows.
* MightyGlacier: The Captains are immune to knockback and can both dish out and endure heavy damage. However, they are quite slow.
* PirateGirl: The Crossbower is one of the few female humanoid enemies in the game.
* PirateParrot: The parrots, which appear alongside the pirates.
[[/folder]]

[[folder: Solar Eclipse]]
After a Mechanical Boss has been defeated, there is a 4% chance that the entire day may be a Solar Eclipse, where monsters straight out of horror movies appear in droves to attack the player. It can also be summoned by using the Solar Tablet during the day. The monsters include Swamp Things, Vampires, Eyezor, Frankenstein, The Possessed, Fritz, and Creature from the Deep. Reapers and Mothron appear after all three Mechanical bosses are beaten, and Butchers, [=NailHead=], Deadly Spheres, Psycho and [=Dr. ManFly=] appear after Plantera is beaten. Almost all the enemies drop their unique loot, including the Broken Hero Sword used to craft the Terra Blade.
* MonsterMash: Loads of classical and horror movie monsters spawn during this event.
* ShoutOut: All the monsters are based on various horror movie monsters.
** Swamp Thing: SwampThing.
** Frankenstein: Literature/{{Frankenstein}}
** Fritz: [[TheIgor Igor]]
** The Possessed: [[Film/TheExorcist Posessed Regan]]
** Creature From The Deep: [[Film/CreatureFromTheBlackLagoon Gillman]]

** [=Dr. ManFly=]: [[Film/TheFly1986 Seth Brundle]]
[[/folder]]

[[folder: Martian Madness]]
When traveling around the map after Golem is defeated, one may spot a Martian Probe. If the player gets into its sensors, it will attempt to fly away, and if successful, the Martian Madness event will trigger. The force consists of Martian Walkers, Martian Drones, Martian Officers, Brain Scramblers, Gigazappers, Gray Grunts, Martian Engineers (and their spawned Tesla Turrets), Skutlix, Skutlix Gunners, Ray Gunners, and the boss, the Martian Saucer. All martians will drop Martian Conduit Platings, while the Saucer can drop the Influx Waver, the Laser Drill, the Laser Machinegun, the Xenopopper, the Xeno Staff.
----
* AirborneMook: Martian Drones fly around and attempt to kamikaze the player.
* AlienBlood: Their blood seems to be purple in colour, considering the color of the flesh on their gibs.
* BossInMookClothing: The lightning-quick Martian Saucer. It has four high health cannons that provide it with a plethora of attacks such as BeamSpam and MacrossMissileMassacre, and a DeathRay it will use that deals huge damage. When those four cannons are destroyed... it becomes vulnerable, but will then ''repeatedly'' use the DeathRay attack. Thankfully, you can spare yourself from the beam by hiding underneath some blocks.
* DeflectorShields: The Martian Officer sports these, allowing him to take more damage than the normal martians.
* FlyingSaucer: The Martian Saucer. It can drop a Cosmic Car Key, which allows you to ride your own.
* TheGreys: The martians are based off these.
* TripodTerror: The Martian Walkers.
* TheTurretMaster: Martian Engineers can spawn Tesla Turrets which attack you.
* WaveMotionGun: The Martian Saucer has one of these. It can also drop the Charged Blaster Cannon which can be charged to fire this.
[[/folder]]

[[folder: The Pumpkin Moon]]
By crafting a Pumpkin Moon Medallion and using it at night, the player can summon the Pumpkin Moon. The Pumpkin Moon is similar to the Goblin and Pirate invasions, but it also has some special mechanics of its own. The invasion will progress in waves, each one featuring progressively harder batches of enemies to fight. The player can encounter Scarecrows, Splinterlings, {{Hell Hound}}s, Poltergeists, and [[HeadlessHorseman Headless Horsemen]]. Killing enough enemies will allow the player to move on to the next wave until they reach wave 15, the final wave. Another key difference from the other invasion events is that starting with wave 4, boss-like enemies will emerge. In this case, they are Mourning Wood and Pumpking. The enemies have a chance of dropping gear that surpasses the loot from Hardmode Dungeon, Plantera, and Golem. The chance increases as the player progresses through the waves.
----
* ScaryScarecrows: The first Mook to show up. A-list CannonFodder compared to the other monsters.
* WhenTreesAttack: The Splinterlings and Mourning Wood.
* ZergRush: The basic premise of the first few waves, before the Mourning Wood appears.
[[/folder]]

[[folder: The Frost Moon]]
The Frost Moon works similarly to the Pumpkin Moon, but features even more difficult enemies to deal with. Crafting and using the Naughty Present will make the player the target of an invasion by nightmarish Christmas-themed enemies: living Gingerbread men, Zombie Elves, Elf Archers, Nutcrackers, Yetis, Elf Copters and multiple [[TheKrampus Krampus]]. The Frost Moon also has three "boss" monsters with the Everscream, Santa-[=NK1=] and the Ice Queen.
----
* NintendoHard: The Lunar Events aside, this is ''the'' toughest event in the game yet.
* NonHumanUndead: Zombie Elves.
* ZergRush: The basic premise of the first few waves, before Everscream appears.
[[/folder]]

!!! Pumpkin Moon bosses
[[folder:Mourning Wood]]
An animated dead tree that first appears on Wave 4 of the Pumpkin Moon. It has 12000 health and alternates between firing a volley of flaming spikes straight at the player, and firing embers that linger on the ground for a while, doing damage to players that touch them. When defeated, it has a chance to drop Spooky Wood, a Cursed Sapling, the Stake Launcher, a Spooky Twig, a Spooky hook, a Necromantic Scroll, and its respective trophy (only on the final wave).
----
* FlechetteStorm: Sprays out loads of burning spikes and splinters.
* GettingCrapPastTheRadar: Its name is a play on the term referring to morning penile erections, and the term has also been used as slang for getting an erection during a funeral.
* KingMook: To the Splinterlings.
* MiniBoss: Quite a powerful {{Mook}}, but not too hard to defeat.
* PlayingWithFire Spits flaming pieces of wood at you to attack.
* WhenTreesAttack: A dead, burning tree that tries to kill you.
[[/folder]]

[[folder:Pumpking]]
A cloaked figure with vines that end in scythes for arms, and a pumpkin for a head. He appears on Wave 7 of the Pumpkin Moon and is considered to be the boss of the event with 22000 health. During battle, he will shift his facial expression, which tells you what attack he will use (Grin- chasing player, Open Mouth- burning embers, Angry- scythe projectiles). When defeated, he has a chance to drop the Horseman's Blade, the Bat Scepter, the Candy Corn Rifle along with its ammo, the Jack-o-lantern Launcher along with its ammo, Black Fairy dust, a Spider Egg, and his respective trophy (only on the final wave).
----
* AuthorityEqualsAsskicking: The Pumpkin Moon's final adversary, and the most powerful.
%%* BadassCape
* CallBack: Has some similarities to Skeletron, in that it is a floating body that attacks using two disembodied arms. However, Pumpking has some nasty tricks of its own, like firing large scythe-shaped projectiles at the player.
* SinisterScythe: Has two for arms.
* PlayingWithFire: Can conjure flaming scythes and also spit embers at you.
* PowerFloats: Constantly floats around the area, making it somewhat annoying to hit him.
[[/folder]]


!!! Frost Moon bosses
[[folder:Everscream]]
An animated Christmas tree that first appears on Wave 4 of the Frost Moon. It has 13000 health and fires a volley of razor-sharp pine needles, and also deploys ornaments that explode into shards. When defeated, it has a chance to drop the Christmas Tree Sword, the Christmas Hook, the Razorpine, Festive wings, and its respective trophy (only on wave 15+).
----
* FlechetteStorm: Shoots out a flurry of razor-sharp pine needles
* MiniBoss: Has less health than a boss-level enemy, but still a very formidable foe.
* ImprobableWeaponUser: Can also fire out exploding Christmas ornaments.
* SuspiciouslySimilarSubstitute: Is pretty much a Christmas-themed version of Mourning Wood. However, its attacks can't pass through blocks.
* WhenTreesAttack: A Christmas tree that tries to kill you.
[[/folder]]

[[folder:Santa-NK1]]
A tank-like mecha with the appearance of SantaClaus carrying a Gatling gun and a rocket launcher. It appears on Wave 7 of the Frost Moon and has 18000 health. It attacks by firing its Gatling gun, shooting rockets at the player, launching exploding presents that rain down on the player, and spiked balls that act as very damaging landmines. When defeated, it has a chance to drop the Chain Gun, Elf Melter, and its respective trophy (only on wave 15+).
----
* BackpackCannon: It's used to fire presents that rain down on you.
* BadassSanta: Like the other boss enemies in this event, he won't disappoint in terms of asskicking when he shows up.
* BadSanta: While Santa himself is not evil in ''Terraria'', Santa-[=NK1=] is a Santa-faced tank that tries to blast the player into bloody chunks with machine guns, rockets, and explosive presents.
* DeathFromAbove: Can make it rain down explosive presents on you.
* GatlingGood: Carries an arm mounted Gatling gun, which he will fire upon you with sometimes.
%%* GlowingEyesOfDoom
* HeavilyArmoredMook: It has one of the highest defense ratings in the game.
* KillerRobot: It's a Santa-based robot that attempts to massacre you with a huge arsenal.
* MacrossMissileMassacre: Carries a rapid missile launcher. Unlike the machine gun, the rockets can penetrate blocks.
* MiniBoss: Has less health than a boss-level enemy, but still a very formidable foe.

[[folder:Ice Queen]]
A large, floating feminine figure that appears to be made of ice. She appears on Wave 11 on the Frost Moon and is considered to be the boss of the event, with 34000 health. Her behaviour involves flying around quickly while firing freezing waves, attempting to hover over the player while raining ice shards, and spinning around in one spot to fire ice shards everywhere. When defeated, she has a chance to drop the North Pole, Blizzard Staff, Snowman Cannon, a Baby Grinch's Mischief Whistle, Reindeer Bells, and her respective trophy (only on wave 15+).
----
* AnIcePerson: Quite literally by the looks of it. As well as the fact that almost all attacks she has mainly consist of spewing shards and waves of ice at her opponents.
* AuthorityEqualsAsskicking: She's an ice ''queen'' and she is an utter nightmare to face. As well as the fact that she is the deadliest enemy on the frost moon.
* DarkActionGirl: When she appears it's a ThisIsGonnaSuck moment for some players as she is no slouch in her objective to put you down, sometimes succeeding as well. Even exceptional terraria players sometimes find her a bit of a handful.
* EverythingsBetterWithSpinning: Can spin around to fire out a huge storm of shards.
* FlechetteStorm: Fires out loads of ice projectiles.
* GodSaveUsFromTheQueen: She's presumably a queen of sorts, and is an incredibly nasty enemy and the boss of the Frost Moon.
* LightningBruiser: The Ice Queen's power is surpassed only by how ''insanely'' fast she is. She also has more health than Plantera!
* PowerFloats: Constantly floats around the area, making it very annoying to hit her.
* StandardStatusEffects: Can cause you to get chilled or even frozen.
