The player character starts off with nothing but a shortsword, pickaxe, and axe. (If you bought the Collector's Edition, you also get a carrot which you can use to summon a pet bunny.) Over the course of the game they will explore the world, build a home, find treasures, defeat ever more challenging foes, and eventually, plunge the world into a battle between the ancient spirits of light and dark.
- Badass: Over the course of the game you will run into various unspeakable horrors, and if you are armed and prepared enough, you can kill said horrors in combat. Then you get even stronger and start farming them.
- Clothes Make the Superman: Although the player can become intrinsically more durable and powerful by consuming magical crystals (and can temporarily augment their power with potions), a large part of the player's power resides in the clothing and accessories that they're wearing. Often, these items are enchanted to bestow perks in addition to their function (for example, "Armored" Rocket Boots increase your defence as well as allowing you to fly).
- Curb-Stomp Battle: As the player becomes more powerful, they will start becoming able to steamroller enemies that previously put up a good fight. By the time you unlock Hardmode, you could be one-hit-killing many regular enemies.
- Did You Just Punch Out Cthulhu?: Many of the bosses the player character fights are Eldritch Abominations — in some cases, they are literally parts of Cthulhu himself. By the end of the game, he/she beats the Moon Lord, the brother of Cthulhu and the closest it gets to the real deal himself.
- Heroic Mime: The player character has no dialogue, but communicates with NPCs just fine.
- He Who Fights Monsters: Eventually after punching out many a Eldritch Abomination, the amount of sheer power that the character gains effectively makes them one themselves.
- Humanoid Abomination: An end game character is both much more durable than the average mortal and fully capable of wielding weapons and magics that are nearly cosmic in scope. They can have minions made of star matter, armor forged solar energy and other worldly metals, weapons that summon falling meteors with every swing, ect. Very little about how the player fights is at all human in the end and a battle involving a high tier player can look outright terrifying from an outside perspective.
- Kleptomaniac Hero: You can take everything. Literally everything. Found an underground cabin? You can loot any treasure chests that are in it. Then take the chest. Then steal all the light fittings. Then disassemble the walls and take those too.
- Nice Job Breaking It, Hero: By killing the Wall of Flesh, the player turns a slightly corrupted world into one threatened to be overrun by huge, competing, pockets of Hallow and Corruption or Crimson.
- One-Man Army: The player will kill thousands of enemies over the course of a full game. The game awards the player with banners for every 50th kill of a particular enemy, and the player can also obtain a Tally Counter which tells them exactly how many enemies of each type they have killed. In some of the special events, such as the Goblin Invasion, they actually do take on entire armies single-handedly.
- Person of Mass Destruction: The amount of devastation you can wreak is cataclysmic. It also doesn't help that your weapons tend to be stuff along the lines of Wave-Motion Prisms , rapid-fire rocket launchers or swords that literally pull stars from the heavens and send them crashing onto your enemy.
- Was Once a Man: The player starts out perfectly baseline mortal, although as time goes on and they start both gathering all sorts of energies and weaponry, they eventually become an unnatural Physical God.
- You Gotta Have Blue Hair: The player character can have any hair color, and the random character generator will happily give you blue, pink, or any color of hair.
As a Whole
All NPCs 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.
- Action Girl: Each and every one of the female NPCs can defend themselves when push comes to shove.
- Action Survivor: Most of them are relatively normal people with normal jobs- unfortunately, being 'normal' isn't enough to protect you in the Death World that is Terraria.
- Badass Crew: They can all participate in combat, and can easily become this if enough are gathered in one place.
- Damsel in Distress/Distressed Dude: The Goblin Tinkerer, Stylist, Mechanic and Wizard are all initially found tied up in one place or another, and must be freed to be recruited.
- Dungeon Shop: They can live anywhere that isn't the Corruption or Crimson, as long as it fits the requirements for a house—including underground, producing this trope.
- Idle Animation: Are prone to these when the PC isn't interacting with them. This includes talking to and playing games with fellow NPCs and sitting on nearby chairs.
- Improbable Weapon User: Most of the NPC's whose functions aren't directly related to combat tend to be this. Examples include the Nurse and her needles, the Party Girl's Confetti Guns, and the Truffle's spores.
- Love Dodecahedron: The Nurse likes the Arms Dealer. The Arms Dealer reciprocates, but is also not above flirting with the Dryad and Mechanic, neither of which like him back. The Mechanic, meanwhile, has a mutual attraction with the Goblin Tinkerer, but neither of them is willing to voice it.
- Took a Level in Badass: Pre-1.3, the NPCs were defenceless against enemies and reliant on the player deal with attackers. The 1.3 update armed them and made the NPCs ready to fight anything that invades the town. And there's a second level of this too; once you reach Hardmode, the NPCs switch to more powerful weapons.
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.
- The Generic Guy: He's just a guy.
- The Scrappy: Invoked. He got hate from the beginning for appearing in every world, being unkillable, and subject to mass Artificial Stupidity. At this point he's even become the scrappy in-game, with other NPCs occasionally making comments about how much they hate him.
- The Smart Guy: If you give him a crafting material, he can tell you everything you can make with it and the recipe to make them. He will also tell you your next general objective.
- The Straight and Arrow Path: Uses a simple Wooden Bow to defend himself if forced into combat. Come Hardmode, he upgrades to flaming arrows.
- Voodoo Doll: You can find his in the clutch of Demons flying about in the Underworld. Equipping it allows the player to attack the Guide even though NPCs are normally immune to player attacks, and tossing it into lava instantly kills him. However, a doll incinerated in the Underworld (whether tossed by a player or simply dropped by a killed Demon and not caught) will summon the Wall of Flesh.
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.
- Bunny-Ears Lawyer: Lies that he doesn't periodically sell junk and believes the moon is made out of cheese yet is essential early on, all the while keeping to his promise that his prices aren't high as they could be.
- Crutch Character: The wares he sells are useful in the early game, but by the time Hardmode comes around just about all of them have been surpassed in function or usefulness.
- Honest John's Dealership: 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.
- Knife Nut: If forced into combat, he will defend himself with throwing knives.
The nurse will move in once a player has found a heart crystal to expand their maximum health above the starting 100. For a price, she can restore the player back to full health in an instant, and remove any debuffs.
- All Periods Are PMS: 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.
- Amusing Injuries: Several of her lines has her casually mentioning re-attached body parts or other grievous wounds.
- Combat Medic: Will heal herself or other wounded NPCs after attacked, and when not helping her allies stay alive she'll be fighting off enemies with poisoned needles.
- Dr. Jerk: She tends to become a bit sarcastic, especially when the player wants her to heal them at high health. Approach her on the brink of death, and she'll quickly lose this attitude.
- Healing Shiv: She also throws needles at the NPCs to heal them, and will occasionally use them to heal herself. She throws poisoned needles at enemies instead.
- Hello, Nurse!
- Tsundere: The Nurse can come off as this: Some of her quotes suggest a Team Mom mentality, others that she only sticks around because you pay her.
- Turn Your Head and Cough: One of the random quotes when you talk to her, even if your character is female.
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.
A trader and purveyor of dyes, who wears a colorful Arabian-styled outfit. He sells the Dye Vat, which allows the player to start making their own dyes from natural resources. If you bring him particularly exotic plants, he will trade them for special, magical dyes.
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.
- Ax-Crazy: This guy is a little too fond of explosive tumult.
- Grenade Spam: Defends himself through the use of Grenades.
- Leaning on the Fourth Wall: If you talk to him, he may ask you to sign a "Griefing Waiver".
- Our Dwarves Are All the Same: 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.
- The Rival: To the Arms Dealer.
- Stuff Blowing Up: His speciality.
- Your Answer to Everything: Got a problem, any problem? Easy — blow it up.
The only child NPC, who can first be found sleeping out on the ocean. He gives out rewards in exchange for finding special, rare fish.
- Bratty Half-Pint: He's possibly the most annoying character in the game. At times he even refers to the player as an errand boy.
- Conveniently an Orphan: He may occasionally mention that he's parentless, which partially justifies why he can be found in the middle of nowhere in the Crapsaccharine World that is this game.
- Infant Immortality: 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 "[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.
- Knife Nut: Throws Frost Daggerfish to fight.
- Small Name, Big Ego: 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.
- Spoiled Brat: He frequently screams that he wants the daily quest fish immediately.
A new NPC introduced in 1.2.3 that is found inside a spider nest, bounded by webs and can be freed. She can change your hair style. She also sells various hair dyes.
- Ax-Crazy: Downplayed Trope 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.
- All Periods Are PMS: During the Blood Moon, which the devs have confirmed is a joking reference to periods, she threatens you with her scissors and razor.
- Color-Coded Multiplayer: In multiplayer servers, she sells Team Hair Dye that makes the player's hair change colors depending on what team they're on.
- Diegetic Interface: Many of her hair dyes can be used as Dead Space-style indicators such as life, mana, depth, biome, team, time, etc.
- Hairstyle Malfunction: Possibly. Upon her death, her head and hair split into two different chunks, unlike other long-haired NPCs. What little hair is attached to her head is a spiky, misshapen 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.
- The Fashionista: She's all about the freshest hair styles, defends herself with Stylish Scissors and has got a nice dress and pair of high heels.
- Shear Menace: Uses Stylish Scissors when forced to fight monsters.
- Serious Business: Bad hair days. She may mention a disastrous 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.
The party girl moves if you have at least 14 NPCs 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.
- All Periods Are PMS: She's the only female NPC that averts this during the Blood Moon.
- Genki Girl: Just like the pony she's based off, most of the thoughts running through her mind are about fun and parties.
- Improbable Weapon User: Uses Confetti Guns and Happy Grenades in self-defense.
- Joke Item: All of her items have no real significance for actual combat or other tasks but just there to, well, party.
- Lethal Joke Item: 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.
- Rose-Haired Sweetie: She's cheerful and optimistic and loves parties, and she's the only female NPC who doesn't become rude or grouchy during a Blood Moon.
- Shout-Out: She is a very blatant shout out to Pinkie Pie, she has blue eyes, dark pink hair, a love for parties, etc. And she can have names such as Sparkle and Trixie.
- Where the Hell Is Springfield?: According to her, the world of Terraria is somewhere on Earth - she mentions that she's been to Sweden.
A centuries-old Nature Spirit, who will move in if you have defeated one of the regular pre-Hardmode bosses. She sells various natural items like acorns and seeds, and she can tell how corrupt the world has become (and will rebuke you for it).
- All Periods Are PMS: During the blood moon but not as bad as the Nurse and Mechanic.
- Garden Garment: She's clad in naught but vines and leaves. Players can buy it during Halloween and wear it themselves.
- Green Thumb: 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 regeneration, and gives them the Thorns ability. The more bosses you defeat, the more powerful the barrier gets against enemies.
- Ms. Fanservice: Not entirely visible in game, save for a risqué painting of her that can appear in the dungeon, but definitely in most fanart.
- Nice Girl: She's one of the kinder NPCs in the game (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.
- Our Fairies Are Different: 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.
- Really 700 Years Old: "I wish [Arms Dealer] would stop flirting with me. Doesn't he realize I'm 500 years old?"
- Shout-Out: "The sands of time are flowing, and you are not aging gracefully."
- Stripperiffic: Those vines don't cover a lot of skin.
- Well-Intentioned Extremist: She encourages the player character to make the world a Crapsaccharine World by spreading the Hallow, although as of 1.3 she'll praise the player even more for completely purifying the world.
- You Gotta Have Blue Hair: Her hair is grass green and done up in a long, curling braid.
He moves in after you find a gun. He sells guns and bullets, and will also sell you illegal gun parts if you catch him at the right time.
- Arms Dealer: Of the Gun Shop Owner type. He can sell you illegal parts, however.
- Blood Knight: 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 Jerkass Ball.
- Casanova Wannabe: 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.
- Covert Pervert: If the Halloween event is any indication, he's not above having spare of the Nurse's clothes lying around and selling them.
- Double Entendre: 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 Flintlock Pistol pre-hardmode, or a Minishark post-hardmode.
- Kinetic Weapons Are Just Better: Notice how he only sells weapons and ammo that are kinetic?
- More Dakka: The guy loves his firearms. He also sells the infamous Minishark, which can then be upgraded into the extremely fast-firing Megashark.
- The Rival: To the Demolitionist.
- Shotguns Are Just Better: He sells them in hardmode.
- You Do NOT Want To Know: It's best he didn't answer HOW he made the Minishark, even stating this trope's name in a conversation with the player.
After the player repels the first Goblin Invasion, the Goblin Tinkerer can be found underground. He is an invaluable asset to any player, for he can reforge the player's items to make them more powerful; he also sells a couple of items that are extremely useful in the mid-game (Rocket Boots for flying, and the Tinkerer's Workshop for combining items).
- Expecting Someone Taller: Lampshaded.
- Grappling-Hook Pistol: Sold for 2 gold in case the Randomly Drops were unkind that you couldn't find an actual hook for one.
- Interspecies Romance: 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.
- Lampshade Hanging: 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.
- Luck-Based Mission: 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...
- Our Goblins Are Different: 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.
- Ship Tease: He's always asking about the mechanic.
- Shout-Out: His name is a reference to Warcraft III's Goblin Tinker.
- "Hey, does your hat need a motor? I think I have a motor that would fit exactly in that hat."
- "Yo, I heard you like rockets and running boots, so I put some rockets in your running boots."
- Spike Balls of Doom: Throws Spiky Balls in self-defense against monsters.
- Will They or Won't They?: Toward the Mechanic.
The Witch Doctor moves in after defeating the Queen Bee. She/He sells the imbuing station and various tribal-themed accessories and items.
- Ambiguous Gender: None of the NPCs' 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; these statues can be used to teleport random NPCs of the corresponding gender.
- Ambiguously Human: He may or may not be a Lihzahrd.
- Blow Gun: His Weapon of Choice.
- Witch Doctor: It's in the title, after all.
Formerly a slave of Skeletron who could be found wandering outside of the dungeon, he moves in once his master has been slain, selling clothes.
- Bad Powers, Good People: From 1.3 onward, he will fend off invading monsters by launching magical skulls at them.
- Dark Is Not Evil: Going by his means of self-defense and the fact Skeletron bursts out of his corpse if you personally kill him at night, the Clothier still has some connection to Skeletron even without his curse. However, he's just another friendly NPC who never harms the player or the other NPCs on his own, and none the items he sells have any application in combat either.
- Demonic Possession: Considering he has Red Eyes, Take Warning before he's set free as well as the fact that Skeletron bursts out of him, it's heavily implied that this is the case with him.
- Earn Your Happy Ending: He's extremely grateful towards the player for freeing him from Skeletron's control.
- Ludicrous Gibs: He violently explodes into Skeletron if you ask him about the curse if he hasn't been freed yet.
- Shout-Out: Nearly every line he says is a reference to a Tom Hanks movie.
- Spell Book: Uses the Book of Skulls to attack monsters. In hardmode, he begins using a special version that also inflicts the Shadowflame debuff on enemies.
- Video Game Cruelty Potential: If you want to obtain his hat, you need to get him killed, and if you want to challenge Skeletron again you need to kill him yourself while you are equipped with his voodoo doll at night.
- Voodoo Doll: Now dropped by Skeletons in the dungeon, in-case you aren't bothered to build an elaborate lava trap to get his hat. Killing him this way will summon Skeletron again if it's night.
Like the goblin, she's also bound, and found in the dungeon. She sells wires and wiring tools.
- All Periods Are PMS: During the blood moon.
- Blind Without 'Em: If you talk to her shortly after rescuing her, she may mention that she's dropped her contact lens and is desperately looking for it.
- Distressed Damsel: While he was still cursed the Clothier tied her up and tossed her into the dungeon, and the player has to save her before she moves in.
- Interspecies Romance: She's a human, and has a crush on the Goblin Tinkerer.
- Oblivious to Love: 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.
- Ship Tease: She's always asking about the goblin tinkerer.
- Will They or Won't They?: Towards the Tinkerer.
- Wrench Wench: She even throws boomerang-like wrenches in self defense.
Once the world is in hardmode, he can appear underground, bound. He sells the materials to make a variety of magical weapons.
- Accidental Misnaming: He frequently calls you by the names of other NPCs of your character's gender.
- Magic Librarian: He sells tomes that are used to craft the Crystal Storm, Cursed Flames, and Golden Shower spellbooks.
- Nice Guy: He tries to be friendly to the player, but if a couple of his possible conversations are any indicator then they aren't exactly working.
- Playing with Fire: Uses the Flower of Fire to fight.
- Robe and Wizard Hat
- Shout-Out: "Someone once told me 'friendship is magic'. That's ridiculous, you can't turn people into frogs with friendship!"
The Truffle will only move into a house within a surface mushroom biome during hardmode and cannot be moved anywhere outside of it. He sells mushroom stuff.
- Blade on a Stick: He sells Mushroom Spears.
- The Friend Nobody Likes: He's at odds with everyone but the Dryad. The Clothier and the Witch Doctor have even gone as far as to try eating him.
- Mushroom Man: All of his possible names are kinds of mushrooms or toadstools to boot, too. He'll also release spores as a means to attack enemies.
- Shout-Out: He doesn't know the "Truffle Shuffle", so stop asking.
- What the Hell, Player?: He calls you out for "stealing his children."
The pirate moves in after defeating the Pirate Invasion and sells cannons primarily, and some other things.
- Defeat Equals Friendship: He looks and fights exactly like the Pirate Captain enemy, which may imply he elected to join the winning side after you trounced his invasion.
- Pirate Parrot: Which you can buy as a pet, but it requires him in the ocean and costs two platinum coins. The Cyborg also implies the Pirate has one of his own after exclaiming how corrosive its droppings are to him.
- Talk Like a Pirate: His manner of speaking.
He will only move in if 1: It's around December 15th to 31st and 2: If you summon, and defeat the Frost Legion. He sells a variety of Christmas-themed decorative items, including christmas trees and trimmings.
The Steampunker moves in if you have beaten at least one hardmode boss. She sells a variety of high-tech, Steam Punk gizmos.
- All Periods Are PMS: During a Blood Moon. Notably, she only has one Blood Moon-exclusive quote warning the player that she's feeling peevish; aside from that, her dialogue is the same as always.
- Sky Pirates: She may mention that she's beginning to consider becoming one.
- Steam Punk
- Wrench Wench: This girl is extremely tech savvy, building and selling some of the most high end machinery in the game like jetpacks and teleporters; occasionally expressing curiosity about the workings of the Cyborg.
The cyborg will move in once you have defeated Plantera and collected a rocket launcher. He sells rockets.
- Ambidextrous Sprite: Either his optical enhancement is more like goggles for both eyes or they can swap between eyes based on how the eye that's shown is always covered.
- Expo Speak Gag: "My expedition efficiency was critically reduced when a projectile impacted my locomotive actuator."
- Grenade Launcher: Or a Proximity Mine Launcher to be exact.
- Logic Bomb: Completely unaffected. In-fact, he makes a joke of it.
- Stuff Blowing Up: Many of his items involve explosions, excluding the nanites.
The Tax Collector moves in after you sprinkle a Tortured Soul, found in the Underworld in Hardmode, with Purification Powder. Every in-game minute (a second in real time), he will collect 50 copper from each NPC that is living in a house up to a limit of 10 gold.
- And I Must Scream: He's trapped in the underworld until you decide to free him.
- Cane Fu: Uses his Classy Cane to fight.
- Heel–Face Turn: He goes from a hostile monster down in the underworld to a recruit-able NPC if you have some purification powder handy.
- The Scrooge: He's based off of this, right down to the personality.
- Ungrateful Bastard: He's created by purifying his Tortured Soul. Anybody would think that would give him a more kinder demeanour in his new lease on life, but sadly, that is not the case.
- Then again, the taxes he collects go straight to you, so he's not entirely ungrateful.
- Because he's immediately changed into a new character when you purify him and only has his standard dialogue (same as he uses when he's in your town), he can't even acknowledge that you just saved him. (This is unlike other NPCs that you save such as the Mechanic and the Goblin Tinkerer, who do have appropriate lines for thanking you.)
An NPC introduced in 1.2.3 that has a random chance of spawning every day once the player has at least two NPCs moved in and no other daytime events are occurring (goblin invasion, pirate invasion, eclipse). Unlike other NPCs, he does not move into a home and instead wanders around near where your home is. He carries a random list of goods each time he appears.
- Badass Cape: He can sell one of four possible vanity capes.
- Booze-Based Buff: Sake sometimes shows up which grants the tipsy (de)buff for twice as long as ale.
- Energy Bow: After defeating Plantera, one of the possible items that can be purchased is the Pulse Bow.
- Katanas Are Just Better: One of the possible items that can be bought.
- Killer Yo-Yo: Has a random chance of selling One Drop's Code 1 yo-yo or the Code 2 when in hardmode, he can also sell two of the counterweights that the Skeleton Merchant does not.
- Revolvers Are Just Better: A possible item he can sell after a Shadow Orb or Crimson Heart has been smashed.
- The Gunslinger: Attacks enemies with his Revolver when threatened pre-hardmode.
- Nice Hat: Wears a blue hat with a feather in it, which he sometimes drops when killed.
- The Straight and Arrow Path: When Hardmode comes along, he switches out his Revolver for a Pulse Bow to attack enemies with.
Introduced in 1.3, the Skeleton Merchant has a random chance of spawning underground. Like the Traveling Merchant, he will not move into a home and will wander around the caverns. He carries a list of goods dependent on current time and moonphase.
- Ballistic Bone: He throws bones at enemies when threatened.
- Cruel and Unusual Death: One of his lines implies that he died by being caught by underground spiders, and they feasted on him until there was nothing left except bones. Oh, and he remembers it completely.
- Dem Bones: He's a skeleton, albeit a friendly one.
- Glove Slap: During a Hardmode Blood Moon, he carries a glove on a stick, while its damage and critical chance is mediocre at best, it has the single highest base knockback of any weapon beyond the Breaker Blade and is great for repelling enemies not entirely immune to knockback.
- Killer Yo-Yo: 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 Yoyo Glove that allows the equivalent of Dual Wielding two of the same yo-yo at once.
- Nice Hat: Wears a large black hat.
- Shout-Out: Several of his names are shout outs to other skeleton or advertiser characters.
Critters spawn in certain environments and are completely harmless and all of them can be caught using the bug net sold by the Merchant and put into bottles or Terrariums. These include birds, cardinals, blue jays, ducks, mallards, bunnies, squirrels, fireflies, butterflies, goldfish, worms, grasshoppers, mice, snails, scorpions, black scorpions, penguins, frogs, lightning bugs, glowing snails and truffle worms. The truffle worm is used for summoning Duke Fishron.
- Animalistic Abomination: The Corrupted forms of penguins, goldfish, and bunnies. Considering that The Corruption has a reputation for spawning minor Eldritch Abominations, this comes part and parcel. Their crimtane versions in Crimson worlds are even worse.
- Bunnies for Cuteness: Bunnies spawn at random and you can even catch one to put into a terrarium to keep. Although they become less cute during Blood Moons.
- Everything's Better with Penguins: In the snow biome, unless it's a Blood Moon then you should run...
- Gold Makes Everything Shiny: 1.3 brought about gold versions of all critters, which are very rare and worth 10 gold coins each. If they're bait critters then they have 50% bait power.
- Metal Slime: Truffle worms, they burrow away the moment you get too close and spawn rarely. 1.3 introduces gold variants of various critters.
- One-Hit-Point Wonder: Although they actually have 5 HP, they have zero defence and literally any attack will instantly kill them unless it was a weak starting weapon such as the Wooden Hammer.
- Tailfin Walking: When it rains, goldfish shuffle about on land on their tails.
The Eye of Cthulhu
The very first boss fought. It's a giant eye.
- Early Bird Boss: After the player has satisfied a few relatively easy-to-meet conditions, the Eye of Cthulhu may simply decide to show up one night and start attacking, even if it hasn't been summoned. While it's still within reason to defeat it, it's also just as likely that the player lacks the equipment or skill necessary to fend it off.
- Eldritch Abomination: Well, at least the eye of one.
- Flunky Boss: For the first phase, it shoots weaker Demon Eyes at you.
- Giant Eye of Doom: 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.
- Time-Limit Boss: It will run away if you do not defeat it by dawn.
- Turns Red: Once at half health, it spins in a circle, releasing a small swarm of Demon Eyes and gaining a giant mouth where its iris was. In this state, it no longer shoots Demon Eyes but charges more aggressively. 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 that it uses in proportion to how much damage it's taken.
- Wake-Up Call Boss: It serves this role in Expert Mode, demonstrating that bosses have become much stronger than they were in normal mode. Its movement is upgraded to nearly match The Twins' ability to track the player's position, it releases a large swarm of lesser eyes transitioning into its second phase, and the new Desperation Attack it uses makes it extremely difficult for early-game characters to both hit and dodge the Eye of Cthulhu when it's on its last legs.
The Eater of Worlds
A giant worm and typically the second boss of the game in a Corruption world.
- Asteroids Monster: If you destroy a segment that would leave two intact segments ahead or behind it, the detached segments will become a separate worm that must also be destroyed. At a bare minimum, you have to kill at least half of the Eater of Worlds to kill it permanently.
- Eldritch Abomination: A gigantic worm with eyes all around it's body that heralds from The Corruption.
- Sand Worm: Well, Corruption Worm. Plays this straight if summoned in a corrupted desert.
- Segmented Serpent: Each of its segments is its own entity with its own health bar, and are capable of acting as independent worms so long as two segments are connected.
- Skippable Boss: If you can fish up the Reaver Shark, you can skip the Eater of Worlds. It'll be a bit harder to mine hellstone with inferior armor, but not insurmountable.
Brain of Cthulhu
A giant brain. It is the typically the second boss fought in a Crimson worlrd.
- Doppelgänger Spin: 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.
- Eldritch Abomination: Again, at least the brain of one.
- Flunky Boss: 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.
- Skippable Boss: If you can fish up the Reaver Shark, you can skip the Brain of Cthulhu. It'll be a bit harder to mine hellstone with inferior armor, but not insurmountable.
- Standard Status Effects: On Expert, any Collision Damage with the eyeballs or the Brain can cause the Confused, Poison, Bleeding, Darkness, Broken Armor, or Weak status effects.
- Suspiciously Similar Substitute: 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.
- Teleport Spam: In the second half of the fight.
King Slime is a Giant Slime with a crown. It is a side boss that can be fought at any time.
- And Your Reward Is Clothes: 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.
- Asteroids Monster: It will eschew normal slimes from itself as it takes damage.
- Cool Crown: Now wears one after the 1.3 update, making it look very similar to King Slime from Dragon Quest.
- Flunky Boss: Spawns blue slimes as it takes damage. On Expert, it can also spawn spiked blue slimes.
- King Mook: 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.
- Shout-Out: To Ninja Gaiden with the ninja floating inside it, being a reference to a boss of the same one you fight.
- Shows Damage: 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.
- Skippable Boss: It's entirely possible to never fight this boss. The triggering events are avoidable and it isn't tied to game progression.
- Spike Shooter: 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.
A giant bee. Its larvae spawn inside bee hives and can be fought if broken. Is a sideboss and can be fought at any time.
- Bee Afraid: 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.
- Bee Bee Gun: Can send out smaller bees to attack you.
- Beware My Stinger Tail: Like the Hornets, she can fire out venomous stingers that poison the player.
- Big Creepy-Crawlies: The largest insectoid enemy in the gamenote .
- Berserk Button: Killing the Bee Larva in any of the bee hives will summon her.
- Flunky Boss: One of her attacks is to release a swarm of tiny bees that follow you relentlessly.
- Glass Cannon: The bees she spawns have very little health, but they pack quite a wallop.
- King Mook: A Queen Mook towards the Hornet enemies.
- Mama Bear: Kill her larva and she'll awaken and attack you in retaliation.
- Ramming Always Works: One of her attacks. She's able to fire out bees and stingers, but will also charge the player.
- Skippable Boss: Like the King Slime, there's no particular need to fight the Queen Bee unless you want her loot.
- Spam Attack: In Expert, her attacks get faster she nears death. This can lead to her chaining up charge attacks, or releasing swarms of bees followed by machine gun-like stinger barrages.
- Standard Status Effects: Can poison you with her stingers.
- Turns Red: Only on Expert. Her attack pattern gets faster and more frequent as she loses health.
A giant floating skull and arms that is summoned by talking to the old man at the entrance of a dungeon at night.
- Cognizant Limbs: Both his hands. On Expert, you're required to destroy them, otherwise his head has exceptionally high defense.
- Cycle of Hurting: On Expert, his spinning move upgrades once both arms are destroyed, becoming faster so he can stick to your character for continuous, huge Collision Damage.
- Dem Bones: It's a floating skull with disembodied skeletal arms.
- Dungeon Bypass: Very strongly averted. Try to tunnel past Skeletron and you'll be killed by the Dungeon Guardian, a Nigh Invulnerable Beef Gate 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.
- Everything's Better with Spinning: For the player, anyway. His defense drops when his head is spinning.
- Homing Projectile: In Expert, he fires homing skulls a la the Book of Skulls once you've killed off one of his hands.
- Time-Limit Boss: It will kill you if you do not defeat it by dawn.
- Turns Red: At dawn, it transforms into the Dungeon Guardian and will One-Hit Kill you. In Expert, once his hands are destroyed, he begins firing skulls at the player while also upgrading his spinning attack to perform a Cycle of Hurting.
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, your doom.
- Beef Gate: It's intended to keep you out of the dungeon until you've earned it by defeating Skeletron. If you descend below 0 depth, it spawns. 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.
- Bragging Rights Reward: The Bone Key it drops when killed, which summons a mini-Skeletron pet.
- Dem Bones: A flying skull.
- Doppelgänger Attack: The game treats it as a normal enemy, not a boss, so it is possible for more than one to spawn. It's not uncommon for two to chase you out of the dungeon. Death is pretty much assured when this happens.
- Everything's Better with Spinning: Constantly in this state.
- For Massive Damage: Does 1000 damage on contact, double the max life a player can possess, and impossible to tank without a specific set of gear.
- The Juggernaut: Doesn't stop homing in on you, takes Scratch Damage from everything, One Hit Kills you, and is practically invulnerable to knockback.
- Lightning Bruiser: It can fly faster than anything short of the best mount in the game, and can One-Hit Kill an endgame melee tank build on contact.
- Lost Forever: Vanishes once Skeletron is defeated, so get your Bone Key before you open the dungeon.
- Marathon Boss: You have to run away from it dealing Scratch Damage until its health depletes, which can take quite a long time. The absolute fastest you can kill the Guardian is in about five minutes, with the right equipment, and that's on Normal mode.
- Nigh Invulnerable: It has 9999 HP (which is doubled in Expert Mode), 9999 Defense (turning all attacks into Scratch Damage), and is Immune to Flinching. It can be killed, but only with a lot of preparation.
- One-Hit Kill: Its sole purpose of existence. If it catches you, you're dead.
- Ramming Always Works: It will crash into you at high speed and make you explode into gibs on impact.
- Self-Imposed Challenge: 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.
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.
- Advancing Boss of Doom: 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.
- Beef Gate: The Wall of Flesh will easily kill the under-prepared, to prevent them from unleashing hardmode prematurely.
- Disc One Final Boss: The most powerful pre-hardmode boss you face before you go into hardmode.
- Eye Beams: It fires volleys of purple lasers at you from its eyes, and the time between shots decreases as its health gets lower until it's full-on Beam Spam.
- Eldritch Abomination: Moreso than the other pre-hardmode bosses because it can inflict a Mind Rape on you that forces you to kill it to survive. According to a card, it's the lord of eternal nightmares.
- Flunky Boss: This game loves these bosses a lot.
- Go for the Eye: While both its mouth and eyes are vulnerable, the eyes have zero defence and thus do not benefit from any Damage Reduction, making them the preferred targets.
- Living Structure Monster: The Wall of Flesh is Exactly What It Says on the Tin — a massive, moving wall with eyes and a mouth.
- Load-Bearing Boss: Its death infects the world with large swathes of ever-expanding hallow and corruption.
- Nintendo Hard: Either you're over-prepared or you die. There is no middle ground.
- Time-Limit Boss: You have to defeat it before it reaches the other side of the world and kills you.
- Turns Red: As you wear down its health, it will start gaining speed, belch up leeches more often and will shoot its Eye Beams more often.
- You Will Not Evade Me: 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. Hard-core however...this happens.
Possibly the first of the hard mode bosses faced, it's a mechanical version of the Eater of Worlds.
- Animal Mecha: A giant metal worm.
- Attack Drone: Sends these out.
- Beam Spam: Both its sections and probes can do this from time to time.
- Boss Arena Recovery: Destroying the probes it sends out will get at least one heart and/or a mana star if you've been using magic weapons.
- Damage-Sponge Boss: Has more HP than any other non-composite entity opponent in the entire game, but since all of his segments are individual targets vulnerable to attack, piercing and melee weapons will rack up massive amounts of damage by striking multiple segments on each pass, balancing out the extra health.
- Flunky Boss: The probes it sends out upon being hurt.
- Frickin' Laser Beams: The aformentioned probes will start letting out a barrage of lasers should they be allowed to survive for a bit.
- Segmented Serpent: 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. If someone has already defeated The Twins and has used their souls of sight to build a Magical Harpnote weapon, the boss fight becomes nearly effortless.
- Time-Limit Boss: Runs away at dawn.
A mechanical version of the Eye of Cthulhu, except there are two of them, Retinazer and Spazmatism.
- Breath Weapon: Spazmatism will spew a constant stream of Cursed Flames in his second phase, though at least their range is limited.
- Beam Spam: The lower Retinazer's health is in the second phase, the more it does so.
- Degraded Boss: 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.
- Dual Boss: The only one in the game.
- Eye Beams: Retinazer, Retinazer, Retinazer. It gets worse the lowers its health gets.
- Giant Eye of Doom: Two of them this time.
- Hellfire: Used by Spazmatism.
- Robotic Reveal: Unlike the other mechanical bosses these two appear to be biological until they enter their second phases.
- Short-Range Guy, Long-Range Guy: 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.
- Time-Limit Boss: The two will run away at dawn.
- Turns Red: 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 Beam Spam.
The mechanical version of Skeletron.
- Chainsaw Good: The Prime Saw arm.
- Cognizant Limbs: Has four destructible limbs, each carrying a deadly weapon of their own.
- Crippling Overspecialization: The Prime Cannon arm fires bombs which explode on contact with solid platforms. This means that a floating arena of wooden platforms makes the arm utterly incapable of causing anything other than Collision Damage.
- Dem Bones: Mechanical ones this time.
- Everything's Better with Spinning: Unlike Skeletron, Prime benefits from spinning as his defense actually increases instead of decreasing when he does so.
- Frickin' Laser Beams: The Prime Laser arm.
- Marathon Boss: With his four arms and high HP, Prime can easily drag the fight out until morning if the player's damage output is too low, and unlike the Destroyer isn't made up of hundreds of segments that can all be targeted.
- Multi-Armed and Dangerous: Has four arms as compared to Skeletron's two, and each arm has a different weapon to murder you with on each end.
- Power Pincers: The Prime Vice arm.
- Skele Bot 9000: It's a mechanical skull with 4 arms.
- Throw Down the Bomblet: The Prime Cannon arm.
- Time-Limit Boss: Like Skeletron, Prime has a Dungeon Guardian form and will kill you at dawn.
The true final boss of the console version, Ocram can best be described as a flying Predator head.
- Beam Spam: Its first form loves this.
- Bullet Hell: Not only does it do this itself, but this is also the focus of most strategies for fighting him.
- Call Back: 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.
- Eldritch Abomination: Quite.
- Final Boss: Confirmed to be as such by the (console version's) developers.
- Flunky Boss: 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.
- Giant Space Flea from Nowhere: Has no buildup or references, not even in the item used to summon him. He's also the only non-robotic Hardmode boss.
- Lightning Bruiser: He moves fast and hits HARD.
- Nintendo Hard: He's pretty much impossible to kill without near-endgame to endgame armor.
- Omnicidal Maniac: If you summon it too close to your house/town, it can and will kill your NPCs.
- Turns Red: His second form turns out his eyes, reveals a bigger eye, and also amps up the power of his Beam Spam attack.
A giant plant-like monster fought after the Mechanical bosses when in hardmode.
- Combat Tentacles: Its invulnerable grappling hooks can deal damage, and it sprouts a bunch of smaller, destructible ones when it Turns Red. In Expert Mode, his grappling hooks sprout them too when it Turns Red!
- Berserk Button: If you lure it out of the Underground Jungle biome, it will become more aggressive and damaging.
- Flunky Boss: The plants that it sprouts when it Turns Red.
- Man-Eating Plant: 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.
- Spike Balls of Doom: Spits these out in its first phase.
- Spike Shooter: First phase uses these.
- Turns Red: At half health, the flower will drop off, sprout tentacle plants, and it'll become much faster and damaging.
A giant statue. Summoned by using a Lihzard Power Cell.
- Cognizant Limbs: His arms can be attacked and destroyed separately, though this isn't necessary to beat him.
- Eye Beams: The first phase uses these when its health gets low. The head in the second phase also uses them.
- Fireballs: Spits out bouncing ones.
- Frickin' Laser Beams: The Eye Beams it fires are slower than light.
- Golem: It's a construct created by the Lihzarhd.
- Hyper-Destructive Bouncing Ball: The fireballs the head shoots out.
- Losing Your Head: When he Turns Red. Justified because he's a construct.
- Power Of The Sun: Many of the Golem's drops are associated with daytime and the sun,
- Outside-the-Box Tactic:
- 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 Collision Damage 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.
- Rocket Punch: His arms. The Golem Fist he drops allows the player to do the same.
- Turns Red: Its head flies into the air and becomes invincible when its health is depleted, forcing you to attack its body directly.
A giant fish-pig-dragon hybrid summoned by using a Truffle Worm as fish bait in the ocean.
- Ascended Meme: Was originally supposed to be the boss of an April Fools' Day joke, the Tidal Moon event. While the event isn't real, Duke Fishron is.
- Berserk Button: If you lure him out of the Ocean biome, it will become more aggressive and damaging.
- Bonus Boss: He's the only Hardmode boss that doesn't need to be beaten in order to fight The Moon Lord, and you need to go somewhat out of your way in order to summon him.
- Bubble Gun: Spits homing bubbles at the player.
- By the Lights of Their Eyes: 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.
- Desperation Attack: 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.
- Flunky Boss: Summons Sharknadoes and Cthulhunadoes that spew out flying shark projectiles called Sharkrons.
- Flying Seafood Special: He's a huge flying fish.
- Glowing Eyes of Doom: When he Turns Red.
- Homing Projectile: His bubbles and his Cthulhunado typhoon.
- Implacable Man: Got buffed in 1.3—he will repeatedly charge at you if you exit the ocean, instead of charging five times then attacking.
- King Mook: To both a Mook (Pigron) as well as a particular fishing catch (Fishron).
- Lightning Bruiser: Extremely fast, extremely painful, and sports 50000 health, more than most other bosses.
- Mix-and-Match Critters: A fish-pig-dragon creature.
- Nintendo Hard: 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 gets pissed.
- Ramming Always Works: Has a high tendency to ram the player.
- Shout-Out: Has the ability to summon Sharknadoes.
- Trademark Favorite Food: He can only be summoned via a Truffle Worm.
- Turns Red: Gains Glowing Eyes of Doom, 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, the player gains an attack and speed buff.
- Victor Gains Loser's Powers: 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 Turn Red when low on health.
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.
- Apocalypse Cult: He's the leader of them.
- Big "NO!": He says this upon death.
- Doppelgänger Attack: If you fail to interrupt his Doppelgänger Spin, the copies follow him around in an upside-down 'V' formation and are able to attack you. They can't be damaged or destroyed until his next spin, which will cancel them out if you do it right.
- Doppelgänger Spin: After several magic attacks, he'll create several copies of himself surrounding a runic circle. If you don't hit the original (distinguished by a yellow vertical stripe on his hood, among other minor differences), it becomes a Doppelgänger Attack and he summons a phantasm dragon. Each time you fail this, he gains more copies until you get it right.
- Evil Sorceror: Very much so.
- Evil Sounds Deep: His voice sounds inhumanly deep as he prays to the stone in Black Speech before absorbing it and turning his attention to you.
- Fire, Ice, Lightning: Can cast homing fireballs, ice crystals that fire ice spikes, and lightning bolts.
- Humanoid Abomination: The Lunatic Cultist may look human, but his exceptional magical strength as well as his voice, which borders on Voice of the Legion, heavily implies that he is something not of this world.
- Instant Awesome, Just Add Dragons: He can create a circle that summons a huge phantasm dragon.
- Instant Runes: He will create a massive runic circle just before creating a doppelgänger and attacking.
- Meaningful Name: He's lunatic in both senses of the word—crazy, and also moon-related.
- Unstable Equilibrium: The fight with him can either be reasonably difficult or downright impossible, depending on your ability to interrupt his Doppelgänger Spin.
- With My Dying Breath I Summon You: He summons the four Celestial Towers when defeated.
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.
- Amazing Technicolor Battlefield: All of them turn the background to an ominous moon with coloured background when fought.
- Eldritch Abomination: All four of the pillars are some kind of otherworldly aliens.
- Flunky Boss: 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.
- Mook Maker: 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.
- Our Wormholes Are Different/Swirly Energy Thingy: The Vortex Pillar creates these around the player, which spawn Alien Hornets.
- Playing with Fire/The Power of the Sun: 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.
- Star Power: Of the Lovecraftian sort. The Stardust Pillar is able to create "stars" around it that spawn Star Cells and Milkyway Weavers.
- Shock and Awe: The portals created by the Vortex Pillar can sometimes shoot a bolt of lightning at you, instead of spawning more Mooks.
- Stationary Boss: They don't move at all, and none of them apart from the Solar Pillar are directly capable of attacking you.
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.
- Attack Its Weak Point: 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.
- Background Boss: Stays in the background all the time. However, touching its eyes (or where they used to be) will deal Collision Damage.
- Boss Vulnerability: Each of the targetable eyes are a Wait Them Out sort, while the heart is Always Vulnerable once it's exposed.
- Cognizant Limbs: The eyeballs in his hands and his Third Eye can attack separately and must be destroyed for him to expose his core.
- Cthulhu Mythos: Heavily resembles Cthulhu. His eyeball minions are even called "True Eye Of Cthulhu". Word of God has stated that he is Cthulhu's brother.
- Damage-Sponge Boss: His component parts have collectively more health than anything in the game. His Third Eye and heart have more health than every other boss save the Destroyer.
- Darkness Equals Death: 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.
- Eldritch Abomination: An eldritch horror from the depths of space.
- Evil Is Bigger: The largest enemy in the game as of now.
- Eyes Do Not Belong There: Has an eye in each of his hands.
- Final Boss: Is this for the entire game.
- Flunky Boss: When each eye is beaten, they will become an invincible flunky that attacks on its own.
- Kaizo Trap: During his death animation, the holes where his weak points used 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.
- Life Drain: 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.
- Mighty Glacier: The most powerful boss, and yet also one of the slowest.
- Power Floats: Floats around the area effortlessly.
- No Sell:
- He's immune to lifestealing effects from the Spectre Armor and the Vampire Knives when he's leeching energy from you.
- As of 18.104.22.168, it's impossible to "cheese" him via using Mercy Invincibility from other sources of damage—he will still hit you.
- Nothing Is Scarier: Before he appears, the background music ominously disappears.
- Sequential Boss: His three main eyes must be destroyed first, then his core will open.
- Super-Persistent Predator: Will chase the players across the map. 22.214.171.124 made it such that he just teleports right to you if you get too far from it.
- Standard Status Effects: Moon Bite is of the Decover type, preventing Life Drain effects from working on him.
- Stripped to the Bone: When beaten, his skeleton drops to the ground.
- Wave Motion Gun: Can fire one of these from his Third Eye. 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.
- You Will Not Evade Me: The 126.96.36.199 update made it such that he teleports right to you if you get too far from him.
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.
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.
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.
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.
The Sand Elemental uncommonly appears in a Hardmode Desert biome during a sandstorm.
The Ice Golem uncommonly appears in a Hardmode Ice biome during a blizzard.
- Eye Beams: Shoots Freeze Rays at the player from its eyes.
- Freeze Ray: Its Eye Beams have a chance of chilling or even freezing the player.
- Golem: One that's made of ice.
- An Ice Person: Its attacks deal icy damage and can freeze the player.
- Mighty Glacier: Moves slowly, but can deal a good amount of damage to the player via its Eye Beams.
The Wyvern sometimes appears in high altitudes in Hardmode.
- Boss in Mook Clothing
- Call a Pegasus a "Hippogriff" / Our Dragons Are Different: Despite having the name of a variant of Western Dragon, the design of this one is more Eastern.
- Instant Awesome, Just Add Dragons: The only ones in the game, not counting Arch-Wyverns in the console version and the Stardust Dragon.
- Lightning Bruiser
- Super-Persistent Predator: Ever try teleporting back home just to get away from these beasts? Don't, because when you're least expecting it, they'll swoop out of nowhere from the sky to finish the job of killing you.
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.
- Barbie Doll Anatomy: She's depicted as fully naked, but lacks nipples or genitalia. Probably a display of modesty more than limitations of the art style.
- Lightning Bruiser: She hits like a truck, moves twice as fast as normal mooks, and is harder to knock back.
- Luck-Based Mission:
- Finding her in the first place is luck, because unlike other enemies she doesn't move. Unless you have the Lifeform Detector, it's entirely possible you'll pass right by without even noticing her.
- She has a 50% chance of dropping the Metal Detector, one of the items needed to craft the Cell Phone. Considering her rarity, this can make obtaining it pretty annoying. In Expert Mode, thankfully, it's a guaranteed drop. Prior to the 1.3 update, getting her banner was even worse, as the drop rate is only 0.5%. Now you just have to kill 50 of her. Good luck with that.
- Horny Devils: Mentioned above, she's naked and fairly attractive. Until she turns that is...
- Schmuck Bait: Hey, it's another NPC. I'll just go up and — Why am I dead?
- Stripperiffic: To the extreme. She wears absolutely nothing.
Appearing in the 1.2 Hardmode Dungeon, the Paladin is a heavily armored knight that throws giant hammers that pass through walls.
- Drop the Hammer: And they will sometimes drop from dead Paladins, and allow you to do the same thing.
- Light Is Not Good: It has really bright armor, and it starts not-so bright chaos.
- Sword Beam: In the form of hammer projectiles.
Appearing in the Hardmode Caverns, the Rune Wizard is an extremely rare enemy with one of the most powerful attacks in the game.
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 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 big boned and 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).
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), mother slimes and their baby slimes, Pinky (see above), Jungle Slimes, Dungeon Slimes that drop keys instead of gel, Lava Slimes that turn into lava in Expert Mode, and The Slime King (see above). In Hardmode, they are joined by the Toxic Sludge that can poison the player, Corrupt slime and its slimelings that can also inflict darkness with a Shadow Slime variant in the Console version, the slimer that 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.
- Blob Monster: Naturally, given that they are gelatinous monsters.
- Glacier Waif: 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.
- Informed Attribute: The gel they are made of is apparently rather tasty (particularly Pinky's), but it's impossible to eat it raw without crafting it into a potion.
- King Mook: The King Slime.
- Metal Slime: 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.
- Money Spider: 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 spawn in droves.
- Rare Random Drop: 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.
- Standard Status Effects: 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.
Once you start exploring The Corruption, there are various, sickly looking, enemies, starting with the Eater of Souls: Small, flying enemies that swarm the player, along with Big Eaters and Little Eaters, all three of which drop rotten chunks. There is also the Devourer 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 Corrupt Slime and its slimelings spawn, along with the 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.
- Airborne Mook: Eaters of Souls, Corruptors, and Slimers can fly around easily.
- The Corruption: An evil, spreading biome that corrupts the land and turns critters into twisted, stronger versions of themselves.
- Elite Mook: 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.
- Eldritch Location: This place compared to the land around it is unnatural. Weird, rotting monstrosities spawn out of deep chasms in the ground and it assimilates the land around it. All of that can tell you that all is not well in that land.
- Flying Weapon: The Cursed Hammer. A flying Hammer of course.
- Giant Mook: Big Eaters, which are slightly stronger than the regular Eaters. World Feeders are this to Devourers.
- Mini Mook: Little Eaters, which are slightly weaker than the regular Eaters.
- Standard Status Effects: 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.
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.
- Animalistic Abomination: Blood Crawler and Blood jellies.
- Artistic License – Biology: 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.
- Big Creepy-Crawlies: Blood Crawlers are basically huge ticks.
- Bloody Murder: Everything about these guys just screams eldritch flesh monsters. The Ichor Sticker shoots ichor at you, described as the blood of gods.
- Body Horror: Face Monsters. Floaty Gross as well, if it's name is any indication; considering that it rather looks like a Gardevoir made out of bodily fluids, one could say it's pretty spot-on...
- Came Back Wrong: The Floaty Gross is classified as an Undead enemy, and it has come back alright, and very very wrong.
- The Corruption: An alternative to the usual black-and-purple one.
- Evil Is Visceral: An evil place with a flesh, blood and gore theme.
- Eldritch Location: Like the Corruption. It's an otherworldly, unnatural place that turns the earth itself into flesh as it assimilates it, and spawns murderous, disgusting, Body Horror-riddled Eldritch Abominations.
- 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.
- Flying Seafood Special: The Ichor Sticker is basically a flying squid.
- Flying Weapon: The Crimson Axe. A counterpart of the Cursed Hammer
- Humanoid Abomination: Face Monsters and to a lesser degree Floaty Grosses.
- Lovecraftian Superpower: The Ichor Stickers wear this on their sleeve.
- Nightmare Face: There's a pretty good reason why the Face Monster is named that way.
- No Sell: Forget using Sunflowers to stop pre-hardmode Crimson, it will uproot them and take over the grass instead.
- Theme Naming: Many of the Crimson creatures and related items begin with "Crim".
- Standard Status Effects: Ichor Stickers inflict Ichor (lowers defence by 20), while the Floaty Gross inflicts Weakness.
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 Light Is Not Good, 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 Teleport Spam 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.
- Crapsaccharine World: Bright, cheerful and healthy for the environment...and filled with vicious fairytale creatures.
- Flying Weapon: 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.
- Flying Seafood Special: Gastropods, if you consider them jellyfish.
- Heavenly Blue: 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.
- Light Is Not Good: 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.
- Lightning Bruiser: Unicorns. Chaos elementals, considering that they can take about as much in damage, move as fast as the player and also Teleport Spam to close the distance even faster.
- Standard Status Effects: Pixies inflict slowness (along with the gastropod) and silence, enchanted swords inflict cursed, light mummies inflict confusion.
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.
- Airborne Mook: The Summoner can fly around to evade your attacks.
- Berserk Button: Apparently you can start a war with them using a flag made of tattered cloth. The Goblin Tinkerer mentions that they have quite the Hair-Trigger Temper.
- Boss in Mook Clothing: The Goblin Summoner, who only appears in Hardmode, is much beefier than the rest of her army and summons homing projectiles on you.
- Fragile Speedster: Thieves.
- Glass Cannon: Archers, they're not as fragile as the wizards but they are made short work of if you get close to them
- The Goomba: 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.
- Hitbox Dissonance: Peons and Thieves have a smaller hitbox than their sprite, allowing them to squeeze through smaller areas.
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.
- Airborne Mook: Parrots are fast flying enemies that deal large amounts of damage if they hit you.
- Authority Equals Asskicking: The Captains are the toughest to deal with out of all the types of pirates.
- Boss in Mook Clothing:
- 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 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.
- Guys Smash, Girls Shoot: 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 crossbower however stays in the back lines firing flaming arrows.
- Mighty Glacier: The Captains are immune to knockback and can both dish out and endure heavy damage. However, they are quite slow.
- Pirate Girl: The Crossbower is one of the few female humanoid enemies in the game.
- Pirate Parrot: The parrots, which appear alongside the pirates.
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.
- Monster Mash: Loads of classical and horror movie monsters spawn during this event.
- Shout-Out: All the monsters are based on various horror movie monsters.
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.
- Airborne Mook: Martian Drones fly around and attempt to kamikaze the player.
- Alien Blood: Their blood seems to be purple in colour, considering the color of the flesh on their gibs.
- Boss in Mook Clothing: The lightning-quick Martian Saucer. It has four high health cannons that provide it with a plethora of attacks such as Beam Spam and Macross Missile Massacre, and a Death Ray it will use that deals huge damage. When those four cannons are destroyed... it becomes vulnerable, but will then repeatedly use the Death Ray attack. Thankfully, you can spare yourself from the beam by hiding underneath some blocks.
- Deflector Shields: The Martian Officer sports these, allowing him to take more damage than the normal martians.
- Flying Saucer: The Martian Saucer. It can drop a Cosmic Car Key, which allows you to ride your own.
- The Greys: The martians are based off these.
- Shock and Awe: The Tesla Turrets deployed by Martian Engineers. It can even cause an "electrified" debuff that deals constant damage, more so if you're moving. The Martian Saucer can drop the Electrosphere Launcher.
- Tripod Terror: The Martian Walkers.
- The Turret Master: Martian Engineers can spawn Tesla Turrets which attack you.
- Wave Motion Gun: The Martian Saucer has one of these. It can also drop the Charged Blaster Cannon which can be charged to fire this.
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 Hounds, Poltergeists, and 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.
- Scary Scarecrows: The first Mook to show up. A-list Cannon Fodder compared to the other monsters.
- When Trees Attack: The Splinterlings and Mourning Wood.
- Zerg Rush: The basic premise of the first few waves, before the Mourning Wood appears. After Wave 15, you can end up being zerged by the bosses.
- Flechette Storm: Sprays out loads of burning spikes and splinters.
- Getting Crap Past the Radar: 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.
- King Mook: To the Splinterlings.
- Mini-Boss: Quite a powerful Mook, but not too hard to defeat.
- Playing with Fire Spits flaming pieces of wood at you to attack.
- When Trees Attack: A dead, burning tree that tries to kill you.
- Authority Equals Asskicking: The Pumpkin Moon's final adversary, and the most powerful.
- Call Back: 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.
- Sinister Scythe: Has two for arms.
- Playing with Fire: Can conjure flaming scythes and also spit embers at you.
- Power Floats: Constantly floats around the area, making it somewhat annoying to hit him.
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 Krampus. The Frost Moon also has three "boss" monsters with the Everscream, Santa-NK1 and the Ice Queen.
- Nintendo Hard: The Lunar Events aside, this is the toughest event in the game yet.
- Non-Human Undead: Zombie Elves.
- Zerg Rush: The basic premise of the first few waves, before Everscream appears.
- Flechette Storm: Shoots out a flurry of razor-sharp pine needles.
- Mini-Boss: Has less health than a boss-level enemy, but still a very formidable foe.
- Improbable Weapon User: Can also fire out exploding Christmas ornaments.
- Suspiciously Similar Substitute: Is pretty much a Christmas-themed version of Mourning Wood. However, its attacks can't pass through blocks.
- When Trees Attack: A Christmas tree that tries to kill you.
- Backpack Cannon: It's used to fire presents that rain down on you.
- Badass Santa: Like the other boss enemies in this event, he won't disappoint in terms of asskicking when he shows up.
- Bad Santa: 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.
- Death from Above: Can make it rain down explosive presents on you.
- Gatling Good: Carries an arm mounted Gatling gun, which he will fire upon you with sometimes.
- Heavily Armored Mook: It has one of the highest defense ratings in the game.
- Killer Robot: It's a Santa-based robot that attempts to massacre you with a huge arsenal.
- Macross Missile Massacre: Carries a rapid missile launcher. Unlike the machine gun, the rockets can penetrate blocks.
- Mini-Boss: Has less health than a boss-level enemy, but still a very formidable foe.
- More Dakka: Carries a gatling gun. Can drop the chain gun which is faster
- Skull for a Head: Damage it enough and its face is revealed to be similar to that of Skeletron Prime.
- An Ice Person: 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.
- Authority Equals Asskicking: 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.
- Dark Action Girl: When she appears it's a This Is Gonna Suck 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.
- Everything's Better with Spinning: Can spin around to fire out a huge storm of shards.
- Flechette Storm: Fires out loads of ice projectiles.
- "Get Back Here!" Boss: The Ice Queen spends much of her time just offscreen using ranged attacks against you, occasionally swooping overhead before flying off again. She's only stationary for her icicle attack, which is fired in every direction.
- God Save Us from the Queen!: She's presumably a queen of sorts, and is an incredibly nasty enemy and the boss of the Frost Moon.
- Lightning Bruiser: The Ice Queen's power is surpassed only by how insanely fast she is. She also has more health than Plantera!
- Power Floats: Constantly floats around the area, making it very annoying to hit her.
- Standard Status Effects: Can cause you to get chilled or even frozen.
- Tactical Suicide Boss: The Ice Queen is usually moving extremely fast, out of range from your attacks. However, once in a while she stops to throw you ice shards, giving you a chance to attack her.
