Main
The Guardian
Click to see his infected form
Click to see his legless form
The main protagonist. He is tasked to monitor a group of test subjects who turn out to be the quartet we are familiar with. He's also the default skin for the player character in multiplayer mode.
- And Then John Was a Zombie: His fate in the Evil Ending.
- Black Eyes of Evil: Has empty and bloody eyes in the Evil Ending.
- Canon Character All Along: The Crawler from Slendytubbies 2D is none other than the Guardian himself.
- Chainsaw Good: Takes Dipsy's chainsaw in the third chapter of 3's campaign and uses it against The Announcer, as well as Po and Noo-Noo in the Good Ending.
- Dragon-in-Chief: Possibly, after the Evil Ending.
- Face–Heel Turn: Can choose to become Noo-Noo's right hand man at the end of 3's campaign.
- Grayscale of Evil: In harmony with his determinant status, the Guardian has white fur and wears a hat with a black and white print. In survival mode, he mainly uses shadowy attacks.
- Handicapped Badass: Losing his legs to become The Crawler doesn't prevent him to be just as dangerous as other enemies.
- Iconic Item: Wears Dipsy's cow-print hat.
- Jerk with a Heart of Gold: Although the Guardian is looking to find out what's going on and do something about it on his own, some dialog options makes him capable of behaving abruptly towards Laa-Laa in Chapter 2 despite the fact she's just had the worst night of her life, even to the point of hitting her. Moreover, one of the endings involves him joining Noo-noo in his plan.
- Light Is Good: Is the main protagonist of the entire Slendytubbies series.
- Light Is Not Good: Can turn into an infected, depending of the endings the player can get in 3.
- Made a Slave: Turns into a monster and becomes one of Noo-Noo in two possible endings.
- Mercy Kill: The player has the choice to make him put Laa-Laa out of her misery in Chapter 2, only if she's still alive.
- Nice Guy: Apart from some dialog options, the Guardian is for the most part portrayed as someone who aims to solve problems. He even considers his former subjects as friends, even though they have never met.
- Player Character: His name and white fur give him a canvas-like feel. He is the player's default appearance in all games, but is only given a proper characterisation in the Campaign. Inverted in 2D and 3's multiplayer, where he appears as an enemy. He's also completely absent from Worlds, except in the optional sandbox mode.
- Rogue Protagonist: A variant; The Crawler first appears in Slendytubbies 2D, but it's not revealed until later that he's actually the protagonist of the first two games. Within Slendytubbies 3 in particular, he plays both a protagonist and antagonist role.
- Sanity Slippage: In Chapter 3, he experiences hallucinations of the four Teletubbies he used to watch. In The Apocalypse DLC, the same thing happens but to a greater degree ; he even thinks that he is going insane.
- Scary Teeth: Has notable ones after losing his legs.
- The Hero: He tries to find clues about the infection and put an end to it.
- The Hero Dies: In every ending in 3 aside from the Good ending.
- The Watcher: His job was to observe Tinky Winky, Dipsy, Laa-Laa and Po, analyse their health and make sure they stayed in their designated surface.
- White and Red and Eerie All Over: As an infected, he has blood dripping from his eyes in the Evil Ending, or red pupils along with his organs dragging on the ground in the Regretful Ending. After an update, his model has been changed and the organs turned into some sort of parasitic creature.
- Who Needs Their Whole Body?: Loses his legs in the Regretful Ending, becoming the one known as "The Crawler".
Noo-noo
"I'm making them better, making things better."
—Noo-noo
The quartet's robotic companion, who cleans their house. After a long and mysterious period of absence in the series, he turns out to be the true Big Bad who infected all the Tubby Custards.
- Adaptational Villainy: The worst thing his original counterpart is capable of doing is being naughty by confiscating the Teletubbies' toys.
- A.I. Is a Crapshoot: Think that Teletubbies are too weak and emotional, and thus created a virus to "make them better" by turning them into stronger and questionably-sapient creatures.
- Bitch in Sheep's Clothing: He's just a small, armless, vacuum Robot Buddy, so nobody would suspect or take seriously the fact that he planned a whole invasion of robots and undead creatures.
- Chekhov's Gunman: He was in the first game as a minor character without any importance, and completely absent in later games, before being confirmed in 3 to be the one behind everything.
- Karma Houdini: In all endings except the "good" one, where he is destroyed.
- Maker of Monsters: He put his virus into the underground machines so that newly-created Teletubbies would already be infected.
- My Death Is Just the Beginning: Even though he is destroyed in the Good ending, he still managed to infect a shit ton of custard and created an army of New Borns that the military will have to deal with.
- Non-Action Big Bad: Clearly, Noo-noo is more of a schemer and a capable hacker than a fighter; after all, he's just a vacuum cleaner. In the Good Ending, the Guardian effortlessly destroys him after defeating Po.
- Robot Buddy: Of the Teletubbies, at first.
- Robots Enslaving Robots: He hacked other forms of artificial intelligence so as not to be disrupted.
- Take Over the World: Wants to make the world "a better place".
- The Chessmaster: The events during the Campaign are not very clear, but it is undeniable that Noo-noo thoroughly planned the vast majority of the incidents. He managed to hijack all the other robots, whose role was presumably to provide security, and then supposedly sent Dipsy to attack the Satellite Station and clear it of all its occupants. On top of that, he corrupted the machines involved in creating Teletubbies and visibly accelerated the process.
- The Dog Was the Mastermind: He was a robotic pet for the Teletubbies, but secretly planned to turn them into mutant creatures.
- The Reveal: The one who allegedly created the virus is none other than the robot vacuum.
- We Can Rule Together: He is surprised by the Guardian's success in defeating The Announcer, and offers to join him, without specifying that he intends to make him a reborn. He sends Po to finish him off for refusing the offer.
Miles
The presumed head of the Military Base, or at least a high-ranking member. He meets the Guardian the day after the massacre and the start of the invasion.
- Cool Helmet: Wears a IHPS helmet that he never takes off.
- Depending on the Writer: Possibly, since the DLC is not written by the original game developper, although this could also be a development.
- Jerkass: Generally behaves like this towards the Guardian in The Apocalypse DLC.
- Jerk with a Heart of Gold: He is shown to be rude towards the Guardian in the DLC, but he clearly wants to sort things out. Anne also points out that he was originally more amiable and that she doesn't understand his current attitude.
- Rude Hero, Nice Sidekick: He is often paired with Anne, and is generally less polite and likable than her.
- The Leader: Of the Military, supposedly.
- Uncertain Doom:
- 3's Bad Ending shows Miles and his group of soldiers struggling to defend themselves against the Newborn army.
- One of the possible ending variants in the DLC shows Miles being (seemingly) knocked unconscious by the explosion.
Anne
An associate of Sgt. Miles, and supposedly another high-ranking member of the Military.
- Ascended Extra: Only appears in the Good Ending, just standing in the background without doing anything or saying a word. She later reappears with a bigger role in the DLC and mini-series, along with Miles.
- Nice Girl: She's pleasant towards the Guardian and tries to void any confrontations between him and Miles.
- Pink Means Feminine: Before being characterised, it was easily assumed that the pink-furred soldier in the background would be a girl. This turned out to be the case.
- Shout-Out: Her name may be one to Anne Wood, one of the creators of Teletubbies.
- Supporting Leader: Anne is often seen alongside Miles, is one of the protagonists in the DLC, and leads a group of soldiers in the mini-series What Comes After.
- The Smurfette Principle: The only known female member within the Military.
The Quartet
The main group of Teletubbies we are familiar with. In general
- Corrupt the Cutie: All of them were peaceful, albeit ignorant, creatures living together with virtually zero problems, until their robotic companion started to turn them into monsters.
- Friend to All Living Things: In the original TV Show, they are friends with everything that is part of the land they live in.
- Killed Offscreen: Although you eventually see their corpses, the exact moment of their death is not shown.
- Unwitting Test Subject: The introduction of 3's Campaign states that they are "hamsters in a cage" and that they are not aware of it.
- You Can Talk?: In the original TV Show, they talk on occasion with very simple sentences. Here, they speak in full sentences.
- Zombie Infectee: Each of them will eventually become infected, Tinky Winky being the first one.
Tinky Winky
Click to see his first mutation
Click to see his second mutation
The oldest and biggest Teletubby, as well as the alleged Big Bad of the series until 3. He is always found roaming within the confines of the Main Land.
- Covered with Scars: After transforming a second time in 3, even though there's no apparent reason for them to be there.
- Evil Sounds Deep:
- Growls can sometimes be hard when playing in earlier versions of 2's Teletubby Land. Speeding these up reveals that it's Tinky Tank speaking to the player, and he has a very deep voice.
- In 3's Chapter 0, Tinky Winky can be heard counting while chasing Po with a muffled pitched-down voice.
- Expy: His second mutation is very reminiscent of a Tank. This is solidified by its official nickname, the "Tinky Tank".
- Faster Than They Look: Tinky Tank is faster than the player in Slendytubbies II and Slendytubbies: Worlds.
- Ghostly Gape: Downplayed. His face is pale and human-like, with lifeless eyes and a wide-open mouth with realistic teeth.
- Purple Is Powerful: He is purple, and is the most recurring threat, with the highest amount of appearances throughout the series.
- Right Behind Me: The more custards you collect in the first game, the faster Tinky Winky gets, to the point where he will be constantly behind you at some point. In the sequel, Tinky Tank runs faster than you but cannot kill you upon collision ; he will try to punch you in the face from a short distance.
- Scary Teeth: On both mutations.
- Shock and Awe: In 3's survival mode, he has the ability to use thunder-based abilities, which includes an electrical explosion spreading around him.
- Super-Persistent Predator: In the first game, and later appearances of this "classic" form, Tinky Winky is constantly chasing the player.
- Transformation Sequence: In 3's Chapter 1, Tinky Winky touches a custard emitting a strange glow, then turns into a massive creature before the protagonist's very eyes.
- You Are Already Dead: If he spots you in Worlds, you are very likely gonna be killed.
- You Don't Look Like You: Seen on different shades of purple throughout the games, and his second mutation has a different face in 3.
Dipsy
Click to see his lake form
Click to see his headless form
The second oldest and second biggest Teletubby. He sits comfortably on the slide inside the house and reminds Po how to turn on the custard machine. His monstrous form is mostly encountered around an isolated Lake.
- Acid Attack: Has one in 3's survival mode.
- Body Horror: His headless body is able to move on its own, while his decapitated head has grown a whole new body which barely looks like a Teletubby.
- Chainsaw Good: Carries a noisy chainsaw of unknown origin.
- Decomposite Character: An In-Universe example. The separation of the body and the head resulted in two separate mutant forms; one with the headless body, and another that grew a new body from the head.
- Expy: His second mutation in 2 was very reminiscent of a Regenerador.
- Evil Sounds Deep: Emits a crocodile-like growl when chasing you. The background ambience in Teletubby Lake is also implied to be him speaking to the player with a deep, monstrous voice.
- I Can't Find My Index: Before the events, he had lost his hat (which is now being worn by a certain white character), then his head, and finally his chainsaw (later retrieved by that same white character).
- Killed Off for Real: In Chapter 3, The Guardian lures the headless body to make contact with a security laser, killing it... kind of. One might assume it was just a dumb corpse powered by the virus, whereas the "real" Dipsy will later become a lake creature.
- Lizard Folk: Has shades of this in his lake form.
- Losing Your Head: He has been decapitated by Tinky Winky, with the head lying on the house slide.
- Offscreen Teleportation: How Dipsy's headless body managed to get all the way to the Satellite Station, considering its lack of senses, and arrive there ahead of the Guardian, is up to interpretation.
- Ominous Walk: Oddly enough, Lake Dipsy in 2 will not run after you like other enemies do, but will take his time, which can come off as Nightmare Retardant. This is greatly Averted in later appearances.
- Playing with Fire: In 3's survival mode, Headless Dipsy can launch a trail of fire across the ground or unleash a spray of bouncing fireballs.
- Red Eyes, Take Warning: Lake Dipsy has red glowing eyes that can be seen from afar.
- Serial Killer: Killed all of the Blue Workers in the Satellite Station.
- Super-Senses: His headless body cannot see nor hear, but seems to react either to closeness or motion, or both. His lake form in the second game can spot you from a long way off.
- Transformation Discretion Shot: The lake transformation is not shown, included or even referenced in 3's Campaign.
- Unblockable Attack: Headless Dipsy in 2 kills you upon collision because the hitbox is on the chainsaw facing forward. In 3, Lake Dipsy has the fastest attack in the game, which is practically impossible to avoid.
- You Are Already Dead: Like Tinky Tank, he is faster than you in Worlds, which means you are likely gonna be killed if he spots you.
- You Don't Look Like You: In both forms. The headless mutation is taller and more muscular in 2, while the lake mutation has drastically changed in 3 and later games/updates but retains many similar features such as red eyes, sharp teeth and a lizard-like vibe overall.
Laa-Laa
Click to see her infected form
The second youngest and second smallest Teletubby. She's had a bad dream and isn't in the mood to play with others. When infected, she is always seen roaming aimlessly around the Outskirts.
- Adaptational Angst Upgrade: Laa-Laa is quite cheerful in the original series, but all we see of her in the Campaign is a girl upset by a nightmare she had, then horrified by the massacre, and she can have her emotional moment during Chapter 2.
- Body Horror: If killed by Tinky Winky in 3's first chapter, she becomes rather unsettling to look at and has constant, intense twitching.
- Break the Cutie: She likely witnesses her friend Dipsy getting beheaded by her other friend Tinky Winky. She then gets lost in a cave where she comes across a hideous monster, then spends her last moments alone in a desolate landscape and has a dialogue with the Guardian that may (or may not) make things even worse.
- Character Tics: Intense twitching.
- Eye Scream: Her eyes get scratched by Tinky Winky if you wake her up in the first chapter before she goes to the beach alone. As a result, she ends up blind with bloody eye sockets.
- Head Crushing: Her fate in the Campaign as a Mercy Kill from the Guardian.
- Hell Is That Noise:
- Emits a loud, low-pitched screech when she detects you.
- In earlier versions of 2's Outskirts, what sounds like female moaning noises seems to be coming from her.
- Light 'em Up: Her early infected phase has bright and glowing abilities in Survival mode.
- Nightmare Sequence: Had one prior to 3's Campaign, which was introduced in Slendytubbies 2D.
- Nothing but Skin and Bones: Thin and quite skinny.
- Sense-Impaired Monster: In Campaign's Chapter 2, she is blind and will move towards the Guardian whenever he moves. In Multiplayer, on the other hand, she can see the player like everyone else.
- Technically a Smile: Despite her condition and everything she's been through, her monster face continues to show what looks like a "smile".
- The Reveal: Depending on the player's dialog choices, and only if she's still alive during Chapter 2, Laa-Laa can learn about the situation in which she and her friends have lived since the beginning. Needless to say, she's not taking it very well.
- Zombie Infectee: If you decide to not wake her in the very first chapter, Laa-Laa will manage to escape from Tinky Winky and surprisingly succeed in travelling through a maze-like cave to reach the Outskirts. However, the virus runs through her veins and she becomes weaker and weaker. The Guardian hesitates between leaving her alone or putting her out of her misery.
Po
Click to see her first mutation
Click to see her second mutation
The youngest and smallest Teletubby. She comes back from a stroll and prepares some custard for her friends. At night, she leaves the house to look for her best friend Tinky Winky. Her first mutation is found inside the Satellite Station while her second mutation can be encountered in the Outskirts in broad daylight.
- Adaptational Jerkass: Depending on the player's dialog choices, Po can be unpleasant towards her friends, especially Laa-Laa, to whom she can coldly express her annoyance regarding her current mood.
- Bodyguard Babes: As The Dragon of Noo-Noo.
- Body Horror: She turned into some kind of insectoid creature with a crooked anatomy, two extra arms growing out of her back, and a skull-like face.
- Coup de Grâce: Inflicts one on the Guardian if you lose your entire health during the last round, leading to the Bad Ending.
- Decoy Protagonist: Playable in 3's Prologue.
- Expy: Her first mutation is essentially a Necromorph.
- Feet-First Introduction: The way she is introduced prior to her boss battle in 3's Campaign.
- Glowing Eyelights of Undeath: Has red glowing irises.
- Hanging Around: Her fate after being caught by Tinky Winky.
- Hyper-Competent Sidekick: She is undoubtedly more dangerous and threatening than Noo-Noo, whom the Guardian effortlessly destroys after her defeat.
- Just Ignore It: Her first mutation in 3's multiplayer has the slowest attack delay in the game, making her laughably easy to avoid.
- Optional Boss: Is only fought if you refuse to join Noo-Noo.
- Playing with Fire: Her most common power as an infected, with her boss fight in the Campaign launching bursts of fireballs and creating rings of flame as a shield, and her fight in Survival adding fire beams and fire blasts.
- Final Boss: Of 3's Campaign.
- Giant Spider: Turns into a big spider-like monster on her second mutation, nicknamed "Spider Po" as a result.
- Monster Mouth: One that is a bit hard to describe
- Multi-Armed and Dangerous: She has two blades at the end of her additional limbs and turns into a spider-like creature on her second mutation.
- Red Eyes, Take Warning: In accordance with her red fur.
- Run or Die: In Slendytubbies 2D, Spider Po constantly stalks you like most enemies, but unlike the others, she moves faster than you when close. This means you have to use obstacles to evade her, or you're doomed.
- The Croc Is Ticking: Makes recognisable ticking noises, indicating her very presence.
- The Speechless: Upon joining Noo-Noo towards the end of Chapter 3, the Guardian can try to communicate with her, without getting any response.
- You Don't Look Like You: In the 2D game, her design is more simplistic; her frame remains unchanged and it's her two arms that have been changed into long limbs ending in blades.
The Best Friends Trio
A secondary group of Teletubbies, who where experiment subjects much like the Quartet. In general
- Ambiguous Situation: It's unclear where they were experimented on and when they became infected. If Unit 437's words are to be believed, then they were in the Main Land, but in this case was it an unseen area, or exactly the same house now inhabited by the quartet?
- Apocalyptic Log: Their story and status as best friends are learned from scraps of torn paper that can be found inside the Cave in 3's Campaign. It is not known exactly who wrote them, but it seems to be either the Cave Tubby or the Arrow Tubby.
- Balance, Speed, Strength Trio: While all enemies have pretty much the same statistics, the design and the abilities of each member of the trio give off this vibe; with the Yeti Tubby (balance), the Cave Tubby (strength) and the Arrow Tubby (speed).
- Bigfoot, Sasquatch, and Yeti: Averted for the Arrow Tubby.
- Electric Torture: One of the punishments they were subjected to during their days as test subjects.
- Escaped from the Lab: Unit 437 states that its "master" has escaped from his designated surface, a detail that is also written on one of the scraps of paper. This strongly suggests that the Yeti Tubby is the one who escaped.
- "L" Is for "Dyslexia": The one who wrote the notes seems to be dyslexic since some letters are flipped.
- No Name Given: Seems to be the case In-Universe, as one refer to one of his friends as "53".
- Terrible Trio: Due to being only seen as infected Teletubbies.
Cave / Claw Tubby
A brown Teletubby with a cruciform antenna. He can be found inside a dark cave in each of his appearances, and made his debuts in Slendytubbies 2D. He is the primary antagonist of Campaign's Chapter 2 if the Guardian decides to travel across the Cave.
- Beast in the Maze: The Cave in Slendytubbies 2D functions like a maze, and the Cave Tubby also appears in the Training Maze of that same game.
- Dishing Out Dirt: Matching his brown color, he can raise a trail of rocks from the ground in 3's Survival mode.
- Facial Horror: It's a bit difficult to describe the state of his eyes, but his left eyeball seems to be popping out of its socket. At the same time, his mouth is greatly extended, as if it had been stretched.
- Glowing Eyes: Has two eyeballs that are oddly glowing in the dark.
- The Grotesque: Has damaged eyes, an extended mouth and the flesh of his left arm is exposed in a way that makes it look like it's falling apart. The flesh in Slendytubbies 3 appears to be shaped like a spike.
- Two-Faced: Kind of. The left side of his face is more disfigured, as if his skin was melting down.
Yeti / Mountain Tubby
A cyan Teletubby with hairs. He can be found in the mountains in each of his appearances, starting with Slendytubbies 2D. He is the primary antagonist of Campaign's Chapter 2 if the Guardian decides to travel across the Mountains.
- An Ice Person: To no great surprise, 3's Survival mode gives him the ability to throw a frozen projectile that explodes on impact, or to raise a trail of icy spikes from the ground.
- Blue Means Cold: He's light blue and his entire appearance is focused around cold imagery: his design, his habitat and his abilities in Survival mode.
- Fur and Loathing: Wears a pair of gloves and shoulder pads that appear to be made of white fur. How did he get them is anyone's guess.
- Hell Is That Noise:
- In Slendytubbies 2D, one could wonder why a child-like voice is coming from this big yeti-looking creature. The Guardian's experience in 3's Campaign supports the idea that it's a voice impression.
- The haunting scream he emits when he spots you.
- Luring in Prey: His ability to mimic a friendly child-like voice allows him to lure his prey. This has been proven to be effective, as it worked at the Guardian.
- Monstrous Cannibalism: Has to eat what he can find to survive in the cold and hostile place where he is currently roaming. This may also include individuals of his own species, as seen in 3's Campaign.
- Scary Teeth: Has a pair of sharp teeth on each side of his mouth, as if they were growing out of his inner cheeks.
- Smarter Than You Look: So far, the Yeti Tubby has displayed a particularly intelligent behavior compared to other infected Teletubbies. He actively seeks out food, has a method of obtaining it by uttering clear words, and according to his slave droid, is capable of sparing lives.
- Spiky Hair: Has this instead of an antenna. This makes him the only known Teletubby to have hairs.
- Vocal Dissonance: Despite his appearance, he is able to mimic a childish and rather feminine voice that sounds a bit like Po's from the original show. His scream, on the other hand, is more fitting.
- Your Size May Vary: He's quite large in each of his appearances, but gets smaller throughout the series, especially compared to the Cave Tubby.
Arrow / Orange Tubby
An orange Teletubby with a triangular antenna. He roams through the Training Maze in Slendytubbies III.
- Beast in the Maze: Appears as the enemy in the Training Maze of 3's multiplayer.
- Early-Bird Cameo: His existence was revealed in a drawing found in the Campaign before finally appearing in the Multiplayer mode after an update.
- Lean and Mean: He's quite lanky, with red lines all over his body, and a pair of rather sporty legs.
- Nothing but Skin and Bones: That's the case to say.
- Playing with Fire: Matching his orange color, the Arrow Tubby in Survival mode can launch a blast of flames or unleash a spray of bouncing fireballs.
- Scary Teeth: Has nasty orange teeth.
Groups
New Borns
Light brown Teletubbies who used to appear in a pair throughout the series inside the Secret Lair, before being revealed to be made in massive numbers after Noo-noo injected his virus into the underground machines. Several variants appear in the Survival mode of Slendytubbies III.
- Absurdly Sharp Claws: The "Berserker" variant has extremely long claws.
- Armless Biped: The common type has no arms, leaving them to attack with headbutts.
- Ascended Extra: The "Runner" Newborns are already playable in 3's Infection mode, then return in Worlds as the most prominent enemies in Collect mode.
- Blade Below the Shoulder: The "Runner" variant has some sort of blade tied to its left shoulder.
- Creepy Hairless Animal: One of their main defining features is their lack of fur, which, according to Noo-noo, is a side effect of the virus. This exposes a pale brown skin that is often seen in mammals without their fur.
- Dead Weight: The "Berserker" Newborns are physically solid and bulky, but that doesn't stop them from moving equally as fast as the others.
- Elite Mook: The Berserkers are the last regular enemies to show up in Survival mode. They are the most durable and they inflict twice as much damage as the others, and even more damage than the mini-bosses. They also start chasing you relentlessly after losing half their health.
- Expy:
- Since the vast majority of enemies in the game are bought models with varying degrees of modification, this is to be expected.
- The Runner Newborns are literally wearing Hannibal Lecter masks.
- Mascot Mook: Sort of. They are the first Slendytubbies-exclusive enemies of the series and some of the most recurring figures.
- Nothing but Skin and Bones: The dark-skinned "Phantom" variant is very tall and skinny next to the rest.
- Shoulder Cannon: One variant can shoot rockets from a shoulder-mounted device. They also have a robotic eye.
- Spider Limbs: The first mini-boss has arachnid-like features and two arms that end in what look like pincers. As a result, he is often nicknamed the "Scorpion Newborn" to distinguish him from Spider Po.
- Tainted Veins: There are veins protruding from their faces, most likely caused by their recent and incomplete creation.
- The Goomba: The small, armless type of New Born shown on the picture above is one to 3's Survival mode. They aren't too fast and are easy to kill, but tend to come in large numbers.
- Underground Monkey: Several variants have been introduced in 3's Survival mode, all of which are more dangerous than the regular ones we are familiar with.
- Visible Invisibility: The tall dark-skinned variant occasionally becomes nearly invisible, which makes a dark puff every time this happens, making them easier to spot
The Military
An organisation of weapon-wielding Teletubbies that appear in the Campaign of Slendytubbies III, and serve as allies in Slendytubbies: Worlds.
- Astonishingly Appropriate Appearance: Soldiers have green fur and wear green helmets, with this color being sometimes associated with the military.
- Color-Coded Armies: Kind of. All of the generic soldiers without characterisation are green, while most New Borns are brown, and these two sides can face off in Worlds.
- Cosmetically Different Sides: The soldier have the same health and behavior than the rocket New Born in 3, and the regular New Borns in Worlds.
- Inexplicably Identical Individuals: There is no clear explanation for the resemblance between pretty much all the soldiers.
The Workers
A group of blue Teletubbies who are affiliated with the Military, and who make an appearance in the campaign of Slendytubbies III.
- A Lizard Named "Liz": One of the victims in the Satellite Station is named "Tobby".
- Chainsaw Good: An infected individual exclusive to 3's Sandbox mode carries a chainsaw.
- Chekhov S Gun: In the cancelled DLC, Tobby's ID card gives the Guardian access to the creation machine.
- Head Swap: The infected worker is just Headless Dipsy, but blue and with a head. He has the same abilities too.
- Inexplicably Identical Individuals: Much like the soldiers, all of the workers have the same appearance, with the occasional different shade of blue.
- Shout-Out: The date birth on Tobby's ID card is the day when Teletubbies first aired on television.
- The Engineer: As pointed out by Ron and their in-game designation.
- The Smurfette Principle: Of all known workers, the first victim to be found in the Satellite Station is specifically identified as female.
The Robots
A branch of droids that have been corrupted by Noo-noo to become part of the Newborn army. They are enemies in Survival mode.
- Ambiguous Situation: The reason behind the creation of the droids is not explained, nor is their function. One of them, Unit 437, claims to have been created by machines, but it's not clear if these are the same machines that created the Teletubbies.
- Beware the Nice Ones: Unit 437 is polite towards The Guardian, but will cook him if he stays longer.
- Grew Beyond Their Programming: The one unit that can be encountered in Chapter 2 displays human traits and explains how it was afraid of being destroyed by the one who is currently its "master".
- SkeleBot 9000: Most of them are meant to look humanoid.
- Slave Race: Implied by the Guardian.
Others
Ron
One of the Workers of the Satellite Station.
- Cruel and Unusual Death: Brutally dismembered by Dipsy's headless corpse.
- Doomed Hurt Guy: He is not capable to move, and later gets found by the wandering undead.
- Sole Survivor: Of the massacre that occurred inside the Satellite Station. At least, for a moment.
- We Hardly Knew Ye: He barely had time to meet the Guardian before being killed off-screen by Dipsy.
The Announcer
A massive fighting robot introduced in the Campaign of Slendytubbies III. It then became the enemy of the Military Base after an update.
- A.I. Is a Crapshoot: Corrupted by Noo-noo.
- Chainsaw Good: Replaces its destroyed right hand with a circular saw during the second part of the battle in 3's Campaign.
- Energy Ball: Can fire a pink projectile which, according to the in-game designation, is Tubby Custard.
- Giant Space Flea from Nowhere: Would you expect a mere voice trumpet to have a big mechanical body?
- Hand Blast: Had one, before it gets destroyed in the Campaign. It is still featured in other game modes.
- Hell Is That Noise: Emits a loud looping alarm when chasing you in 3's Collect mode.
- One-Hit Kill: It is the only enemy capable of killing you with a single melee attack on the easiest difficulty of Survival mode. Justified, as it's a giant robot and the biggest character in the game.
- Promoted to Playable: It is not playable in Versus mode due to its large size, making it one of the only major enemies not to be playable. This has been later made possible with the Sandbox mode.
Newborn General
A unique reborn whose role is to lead an army of Newborns across lands in recent times. He is the last mini-boss in the Survival mode of Slendytubbies III.
- Dark Is Evil: One of the only New Borns to have a dark and rough skin, along with the ghost-like variants.
- Dead Weight: Large and undead.
- Eyeless Face: He apparently has no eyes, as they are hidden by the rough skin on his forehead.
- Fat Bastard: Has a sturdy and massive body, as well as a rough skin that closely resembles solid rock.
- Horned Humanoid: Can be distinguished from the others by his horns, one of which is broken.
- Large and in Charge: Judging by his title, he leads the army of New Borns, and he's one of the biggest.
- Magma Man: Can raise a trail of volcanic rocks from the ground.
- The Dragon: Possibly one of Noo-noo.
Shadow Tubby
A mysterious black Teletubby entity with a bracket-shaped antenna. It can be found in a dream-like realm in each of its appearances, starting with Slendytubbies 2D.
- Ambiguous Gender: Reflecting its enigmatic status, it doesn't have a known gender, although it does seem to lean a little more on the masculine side.
- Casting a Shadow: To no great surprise, it can use dark abilities in Survival mode.
- Dark Is Evil: As demonstrated.
- Enemy Within: Possibly. Word of God stated that it is a personification of the infection, suggesting that it may be seen in some ways, at least once, by each infected host and that it may (or not) control them from the inside.
- Leitmotif: An orchestral tune going faster and faster plays as it begins to chase you.
- Nightmare Sequence: It was part of the bad dream that Laa-Laa mentioned in the very first chapter. In The Apocalypse DLC, the Guardian experiences something similar, although it's possibly not canon since the DLC has been cancelled.
- Nothing Is Scarier: The place where it appears is completely empty and surrounded by darkness. Given its pitch-black body, it can easily blend into the darkness, and all you can see from afar is a glowing smile and a screen getting closer to you until it turns out to be a very large entity.
- Obviously Evil: It is a non-infected, pitch-black and ghostly Teletubby with a bloody grin.
- Our Ghosts Are Different: Although it has an undeniably ghostly appearance, Word of God makes it more of a mental figure than a non-corporeal being.
- Red and Black and Evil All Over: Its entire body is pitch black except for the mouth and the abdominal screen, and the only visible color is the blood dripping from its lips.
- Slasher Smile: The only facial feature it has is a glowing, bloody grin.
- The Ghost: Literally, the entity is indirectly referred to by Laa-Laa, and doesn't appear at all in the story. This is Inverted in the DLC, but it may no longer be relevant due to the cancellation.
Ghost / School Girl
A ghostly school girl who made her first appearance in Slendytubbies 2D. Her presence in the series is completely out of place. Word of God states that she's Laa-Laa's imaginary friend, but there are no further details.
- Adaptational Attractiveness: Her face in 3 is less monstrous and more Animesque, which removes some of the scary factors.
- Blank White Eyes: Has these in 3, compared to the white pupils in the 2D game.
- Casting a Shadow: The Survival mode gives her the ability to throw dark projectiles and to surround herself with them as if they were rotating like a tornado.
- Eerie Pale-Skinned Brunette: A young brunette with pale greyish skin who is just as dangerous as the other enemies.
- Jagged Mouth: Much more visible in Slendytubbies 2D. Her model in 3 tries to achieve a similar result, but it looks more like she's sporting black lipstick.
- Token Human: The only human to make a "physical" appearance in the series. Whether or not there's a reason for that remains largely unexplained.
- Undead Child: She's a ghostly school girl.
