Given the loads of NPC's, monsters, and bosses. It's no doubt that there's a character list for this game. This page also NeedsWikiMagicLove.

[[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 Eldritch Abominations, and if you are armed and prepared enough, you can KILL said abominations in combat,[[UpToEleven then take it even further by FARMING them]].
** BadassNormal: Aside from the health upgrades your character is pretty much normal. Doesn't stop you from going toe to toe with [[EldritchAbomination creatures that look like they've spawned from the deepest darkest depths of your nightmares]].
** BackToBackBadasses/*BadassCrew: If playing on multiplayer servers.
** 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.

* ContinuingIsPainful: Medium and Hard Core, Medium core simply drops all of your items on death (A la ''{{Minecraft}}'') But the items can be hard to locate if you were deep underground. Hard Core however, deletes your character and not your world, so you can create a new character to continue. At the expense of both the items and the gained health/mana from the dead character.
* DeathIsASlapOnTheWrist: Soft core plays it straight, suffer losing half your carried money and get sent back to your natural/set spawn point.
* DidYouJustPunchOutCthulhu: Essentially every single boss fight. As a side note you actually fight the Brain and Eye of Cthulhu.
* 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.
* FinalDeath: Hardcore mode, once the player dies, they drop their items and the character is deleted, unlike ''{{Minecraft}}''[='=]s example, only the player, not the world is deleted, so a new character can be created to continue.
* LightningBruiser: Many players prefer this play method. Agile, fast, able to dish out an extreme amount of pain and can shrug off attacks that would usually turn them into a bloody smear on the ground.
* TheMinionMaster: A possible play style. Proper set-up allows for up to ''18 pets!'' Several weapons also spawn short lived monsters to attack targets taking this trope even further.
* 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]].

[[folder: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 the following criteria specific to the NPC.

!!The Guide
First NPC you start out with, he can give tips and show you what can be crafted with a material, generally regarded as {{the scrappy}}, even by the developers themselves. He is however, used to summon the Wall of Flesh by throwing a voodoo doll of him into lava in the underworld.
----
* TheSmartGuy: Supposedly.
* 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]].


!!Merchant

Moves in after you find grenades/dynamite or craft sticky bombs and can sell you more of them, each explosive having a purpose.

* NonStandardCharacterDesign: So far the only NPC that is shorter than everybody else
[[/folder]]

[[folder:Bosses]]

!!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.
----
* EldritchAbomination: Well, at least the eye of one.
* FlunkyBoss: For the first phase
* GiantEyeOfDoom
* TimeLimitBoss: It will run away if you do not defeat it by dawn.
* TurnsRed

!!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
----
* AsteroidsMonster
* 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!

!!Skeletron
A giant floating skull and arms that is summoned by talking to the old man at the entrance of a dungeon at night. 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. 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
* DemBones
* EverythingsBetterWithSpinning: For the player, anyway. His defense drops when his head is spinning.
* TimeLimitBoss: It will ''kill you'' if you do not defeat it by dawn.

!! 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, or if the player crafts and uses a slime crown. 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.
----
* 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.
* AsteroidsMonster
* FlunkyBoss: Once again
* KingMook
* ShoutOut: To NinjaGaiden with the ninja floating inside it, being a reference to a boss of the same one you fight.

!!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 [[{{FinalFantasyVII}} Breaker]] [[{{BFS}} Blade]] along with it's respective boss trophy and mask. Its death also triggers the spawning of two massive veins of hallow and corruption/crimson as the world goes into hard mode.
----
* AdvancingBossOfDoom
* BeefGate: The Wall of Flesh will easily kill the under-prepared, to prevent them form unleashing hardmode prematurely.
* DiscOneFinalBoss
* EyeBeams
* EldritchAbomination
* 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.
* NintendoHard: Either you're over-prepared or you die. There is no middle ground.
* LoadBearingBoss: Its death infects the world with large swathes of ever-expanding hallow and corruption.
* 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...

!!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
----
* 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.
* FrickinLaserBeams
* MarathonBoss: Has more HP than any other 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: The player can attack multiple segments at one go, allowing them to deplete is massive HP faster.
* TimeLimitBoss: Runs away at dawn.

!!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.
----
* 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.

!!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.
----
* ChainsawGood: The Prime Saw arm.
* CognizantLimbs
* 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 will kill you at dawn.

!!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.

!!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. Then it will expose its heart and start attacking you, allowing you to directly damage it. 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 trophy and mask.
----
* EldritchAbomination: Again, at least the brain of one.
* FlunkyBoss: Much like the Eye of Cthulhu, it summons eyeball-like minions to attack you
* 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.

!!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 hive wand (places down hive blocks), part of the bee vanity set, a nectar to summon a hornet pet, the Bee Keeper (A bee themed sword), the Honeycomb (summons bees when hit) and her trophy and mask
----
* 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.
* EverythingsWorseWithBees
* KingMook: ''Queen'' Mook.
* RammingAlwaysWorks: One of her attacks.
* StandardStatusEffects: Can poison you with her stingers.

!!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.
----
* 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.

!!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
----
* 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}}
* FrickinLaserBeams
* {{Golem}}
* HyperDestructiveBouncingBall: The fireballs the head shoots out.
* LosingYourHead: When he TurnsRed. Justified because he's a construct.
* 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.

!!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. 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.
----
* 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.
* BubbleGun: Spits homing bubbles at the player.
* FlunkyBoss: Summons Sharknadoes and Cthulhunadoes that spew out flying shark projectiles called Sharkrons.
* FlyingSeafoodSpecial
* GlowingEyesOfDoom: When he TurnsRed.
* HomingProjectile: His bubbles and his Cthulhunado typhoon.
* 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.
* 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.
* 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, and Fishron's Wings give the player the Duke's superior air and water mobility.

[[folder: Rare Enemies]]

!!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.

!!Pinky
A rare overworld slime that is tiny and pink. It's hard to hit but, when killed, it will drop a single gold coin, useful for players starting out.
----
* MetalSlime: And an actual slime to boot.

!!Doctor Bones
A zombie that spawns rarely in the jungle (both above and underground) during the night, wearing an archaeologist's hat, who drops it when killed. It's tougher than the regular zombie as well.
----
* MetalSlime
* ShoutOut: Like the rest of the archaeologist's vanity set, to ''Franchise/IndianaJones''.

!!The Groom
A zombie wearing a top hat that spawns during a blood moon, the top hat is also dropped upon death, like Dr. Bones, he also has higher HP than the regular zombie.
----
* MetalSlime
* ShoutOut: It may be a reference to the zombie groomsman in ''Film/ShaunOfTheDead''.

!!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.

!!Clown
A Hardmode enemy that only spawns during Blood Moons. The Clown throws bombs, and, until Patch 1.2, was the only enemy in the game capable of damaging blocks.
----
* MadBomber
* MonsterClown

!![[Film/MontyPythonAndTheHolyGrail 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''

!!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

!!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.
----
* InstantAwesomeJustAddDragons: The only ones in the game.
* LightningBruiser
* OurDragonsAreDifferent: Despite having the name of a variant of Western Dragon, the design of this one is more Eastern.

!!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.
----
* 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...

!!Paladin
Appearing in the 1.2 Hardmode Dungeon, the Paladin is a heavily armored knight that throws giant hammers that 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
* SwordBeam: In the form of hammer projectiles.

!!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: Dem Bones]]

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: The Slime Family]]

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 used to turn into lava, 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.
----
* KingMook: The King Slime.
* MetalSlime: Pinky. Rainbow Slimes count too; they show up very rarely in the Hallow during rainstorms, 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.
[[/folder]]

[[folder: Corrupted Enemies]]

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: Slimers
* TheCorruption: Their native habitat.
* FlyingWeapon: [[DropTheHammer The Cursed Hammer]]. A flying Hammer of course.
* GiantMook: Big Eaters.
* MiniMook: Little 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. 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 enemis include the Crimslime; the Floaty Gross; the Herpling and the Ichor Sticker.
----
* BigCreepyCrawlies: Blood Crawler
* BloodyMurder: 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}} Gardevior]] made out of bodily fluids, one could say it's pretty spot-on...
* TheCorruption: An alternative to the usual black-and-purple one.
* EvilIsVisceral
* {{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
* 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 Hallowed]]

Once hardmode is activated, the hallowed 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.
----
* 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.
* LightIsNotGood: Played painfully straight. However, the Hallow does not force [=NPCs=] to move out unlike the Corruption and Crimson.
* LightningBruiser: Unicorns
* StandardStatusEffects: Pixies inflict slowness (along with the gastropod) and silence, enchanted swords inflict cursed, light mummies inflict confusion.
* TeleportSpam: The Chaos Elementals.

[[/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. 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.
----
* BerserkButton: Apparently you can start a war with them using a flag made of tattered cloth.
* 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.
* TeleportSpam: Sorcerers

[[/folder]]

[[folder: Pirate Invasion]]

The pirate invasion can occur 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 and Parrots. 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.
* 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]].
* 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.

[[/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.

!! 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.
* KingMook: To the Splinterlings.
* MiniBoss
* PlayingWithFire

!! 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
* 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
* PowerFloats

[[/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'' toughest event in the game yet.
* NonHumanUndead: Zombie Elves.
* ZergRush: The basic premise of the first few waves, before Everscream appears.

!! 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
* ImprobableWeaponUser: Can also fire out exploding Christmas ornaments.
* SuspiciouslySimilarSubstitute: Is pretty much a Christmas-themed version of Mourning Wood.
* WhenTreesAttack

!! 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
* 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.
** BadassSanta: Like the other boss enemies in this event, he won't disappoint in terms of asskicking when he shows up.
* DeathFromAbove: Can make it rain down explosive presents on you.
* GatlingGood
* GlowingEyesOfDoom
* HeavilyArmoredMook: It has one of the highest defense ratings in the game.
* KillerRobot
* MacrossMissileMassacre: Carries a rapid missile launcher. Unlike the machine gun, the rockets can penetrate blocks.
* MiniBoss
* MoreDakka: Carries a gatling gun.Can drop the chain gun which is ''faster''
* SkullForAHead: Damage it enough and its face is revealed to be similar to that of Skeletron Prime.

!! 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+).
----

* FlechetteStorm: Fires out loads of ice projectiles.
* GodSaveUsFromTheQueen
* LightningBruiser: The Ice Queen's power is surpassed only by how ''insanely'' fast she is. She also has more health than Plantera!
