- "Naughty Noo-Noo!"

- Four-Temperament Ensemble: Tinky-Winky (phlegmatic), Dipsy (melancholic), Laa-Laa (sanguine) and Po (choleric).
- Free-Range Children: They're supposed to be babies (just like the Target Audience), yet they live on their own with no parental care or supervision. May be justified, as they seem to be some kind of aliens; whatever species they are apparently has very precocious offspring (and a lot of help from technology), and therefore little to no need for parental involvement.
- Friend to All Living Things: They are friends with children, flowers, trees, rabbits, etc.
- Gender-Equal Ensemble: Two guys (Tinky Winky and Dipsy) and two girls (Laa-Laa and Po).
- The Hero: All have a shared role.
- Huge Guy, Tiny Girl: Tinky-Winky (Huge Guy) and Po (Tiny Girl). The two are frequently seen together and the former is the biggest and oldest, while the latter is the smallest and youngest.
- Iconic Item: Tinky-Winky has his infamous purse, Dipsy has a cow-print hat, Laa-Laa has a big orange ball, and Po has her scooter.
- Kindhearted Simpleton: Tinky-Winky, Dipsy and Laa-Laa certainly have enough naivety and indifference to fit this trope, having the simple mind of a young child. Po, not so much, since she does have a bit of an intelligent side to her.

- Pokémon Speak: All of them. They repeat their own names all the time.
- Red Oni, Blue Oni:
- Tinky-Winky and Po are Blue and Red, respectively, with Tinky-Winky's gentle and delicate nature contrasting with Po's more high-spirited and boisterous one. Tinky-Winky is also the Blue to Dipsy's Red.
- Dipsy, however, is the Blue himself to Laa-Laa's Red, being a bit of a stubborn introvert when compared to Laa-Laa's cheerful people-orientedness.
- Laa-Laa's carefree Cloudcuckoolander nature usually makes her the Blue to Po's pluckier, more ambitious Red.
- Savvy Guy, Energetic Girl: Dipsy and Laa-Laa. The former is the most serious one of the group who will occasionally disagree with the others, while the latter is more outwardly cheerful and frequently plays with her enormous ball.

Tinky-Winky displays many effeminate traits such as carrying his handbag and occasionally wearing the skirt while doing a dance, while Dipsy shows a mild dislike for such things and is the more Hot-Blooded and masculine one of the two.
- Ship Tease: Tinky-Winky has one with Po, and Dipsy has one with Laa-Laa. Seeing how frequently both male-female pairs are seen and how many older fans of a particular property tend to ship certain characters with one another, this could be justified. In one episode, a Voice Trumpet even indirectly refers to Laa-Laa as Dipsy's "favourite friend".
- Tomboy and Girly Girl: Po (Tomboy) and Laa-Laa (Girly Girl). Po rides a scooter and is the more rambunctious one, while Laa-Laa is more gentle and has the stronger liking for things such as animals and nature.

- "Tinky Winky bag!"

- Played by Teresa Gallagher
The baby offspring of the original Teletubbies that appear in the 2015 reboot. Their names are Mi-Mi, Daa Daa, Baa, Ping, RuRu, Nin, Duggle Dee, and Umby Pumby.
- Ambiguously Brown: Baa and Duggle Dee have slightly darker skin tones than the other Tiddlytubbies; however, it's hardly noticeable unless they're seen with other Tiddlytubbies.
- Colour Coded Characters: Each Tiddlytubby has a rainbow-themed colour, as follows:
- Red - Duggle Dee
- Orange - Ru Ru
- Yellow - Umby Pumby
- Green - Daa-Daa
- Blue - Mi-Mi
- Indigo - Baa
- Violet - Nin
- Pink - Ping
- Gender-Equal Ensemble: Four males (Daa-Daa, Ru Ru, Duggle Dee and Baa) and four females (Umby Pumby, Ping, Mi-Mi and Nin).
- Iconic Item: Daa Daa's Tiddlynoo, Ping's xylophone, and Umby Pumby's teddy bear.
- The Leader: Mi-Mi, to the other Tiddlytubbies. note
- Pink Girl, Blue Boy: Played straight with Ping and Baa, but inverted with Mi-Mi and Duggle Dee, who are light blue and pinkish-red respectivly.
- Pokémon Speak: Due to their young age, almost all of the Tiddlytubbies can only say their name. Daa Daa is the exception, as he can say "Vroom-vroom!" in addition to his name. Nin and Duggle Dee also say the word "Party!" several times in the episode "Tiddlytubby Party".
- Rainbow Motif: They are all coloured according to the rainbow.
- Still the Leader: Mi-Mi, like RuRu, Nin, and Duggle Dee, wasn't officially introduced until the episode "Tallest Shortest", and was just seen sleeping in the background until then. Daa Daa, Baa, Ping, and Umby Pumby were introduced earlier, in the episode "Babies".
- Super Speed: Downplayed with Daa Daa, whose the fastest Tiddlytubby solely because he rides the Tiddlynoo. Though, the Teletubbies website mentions that Daa Daa "loves revving back and forth extremely quickly on the Tiddlynoo", whichif taken at face valuewould both be absurd and play this trope straight.
- Sleepyhead: Umby Pumby.
- Theme Song: The Tiddlytubbies have one.
- The Twindividual: Nin and Duggle Dee. As the Teletubbies website points out: "The two are inseparable always holding hands and playing with balls."
- Operated by: Mark Dean (Original series), Victoria Jane (2015 series, Season 1), Olly Taylor (2015 series, Season 2-present)"Suck, slurp, suck, slurp!"
The vacuum of the Teletubbies. He is small and blue. He is sometimes naughty and sucks up the Teletubbies' things but gives them back in the end. He also helps out the Teletubbies by cleaning up their messes and cleaning up the house. Some fans consider Noo-Noo to not be a Teletubby.
- "Suck, slurp, suck, slurp!"
- Jerk with a Heart of Gold: At times, Noo-Noo will suck up the Teletubbies' favorite things and run away with them, but he always gives them back in the end.

- Robot Maid: He always cleans up a mess that the Teletubbies make.
- Team Pet: He could possibly be the pet for the Teletubbies.
The Sun Baby
- Played by Jessica Smith (Original series), Berry (reboot)
The baby-faced sun of Teletubbyland. She appears at the beginning and end of each episode, and also pops up randomly to react to whatever is going on.
- Audience Surrogate: Word of God says that the Sun Baby was meant to be this.
- The Face of the Sun: One of the most famous examples on children's television.
- The Hyena: She laughs in almost every scene she appears in.
- Perpetual Smiler: Just like the Teletubbies themselves, she never stops smiling.
- The Unintelligible: Being a baby and all, she never makes any noises other than squeals and giggles.
The big scary lion is an animatronic who entertains the teletubbies and enjoys giving them a good scare. His performance involves hunting and chasing an equally creepy-looking bear.
- Badass Baritone: He had this in the original cut, but later releases changed it to a campier voice.
- Badass Boast: Claims to have big scary teeth, and be scary around the front, back, top, and underneath.
- Cool Board: Because he is a slap of cardboard shaped like a lion, he is unable to walk but can travel amazingly fast on a board with weels on it.
- Eyes of Gold: Has a very uncanny pair of yellow luminous peepers and his pupils often dilate to the extent they turn completely Black in some frames.
- Informed Attribute: His "big scary teeth" ain't that big.
- Harmless Villain: For all his creepiness, he ultimately is just about theatrics, really.
- Nightmare Face: At least for children watching this show. For older people he fits firmly into the Uncanny Valley. He isn't that scary.
- Offscreen Teleportation: He is naturally fast on his wheeled board, but in many scenes he leaves the screen and reappears in a different position, suggesting he can turn around supernaturally fast.
- Oop North: He originally spoke in a cockney accent, but in some dubs, he has a lancashire accent.
- Vile Villain, Saccharine Show: Not actually a villain, but his creepy appearance and the way he is introduced definitely makes him very intimidating, especially given the nature of the show he is in.
- Villainous Breakdown: Is increasingly frustrated as he searches for the bear as his speech is increasingly interrupted with angry growls and when he finally spots her he stops speaking coherently and his vocabulary is reduced to incoherent snarling and maniacal laughter.
- Villain Decay: In the original airing, there was a suspensful build-up to his appearance, and he spoke in a gravely, threatening voice. Serious music would play when he was on the screen, as he stalked the bear. In later dubs he spoke in a softer tone of voice, would meow, silly sound effects would play and the music sounded more derranged but light-hearted.
- Cloudcuckoolander: Tells the audience that she'll tell a joke, her "joke" involving her rolling her each eye independantly and sticking her tongue out.
- Cool Board: Her primary mode of transportation, given that she is a plank of wood shaped like a bear.
- Fragile Speedster: A REAL bear wouldn't flee a lion.
- Informed Attribute: Her brown fuzzy hair. It isn't really there.
- Jump Scare: She uses her "joke" to jumpscare the big scary lion.
- Offscreen Teleportation: She can travel lighteningly fast on her board, but what's weird is there is no clear way she can turn around offscreen as fast as she seems to, and she appears to be able to crouch and stoop despite being a lump of stiff wood.
- Troll: She is this for the lion.
- Vocal Dissonance: Speaks in an upper-class London accent despite being a hulking bear.
