There are nine recurrent characters in ''[=LazyTown=]'', all but three of them played by puppets.

* {{Adorkable}}: While Sportacus is conventionally attractive, well-muscled and very fitness-oriented, many fans consider him adorkable due to his constant optimism, boyish over-excitement, hopeless naiveté and awkward English. His baby-blue eyes and cheesy grin only help the matter.
* AmbiguouslyHuman: He is faster and more agile than any of the human characters and can pull off stunts that most people could only dream of. He also [[OurElvesAreBetter keeps his ears conspicuously hidden under his hat at all times]].
* BadassMustache
* BlitheSpirit
* TheCastShowoff: Sportacus showcases Scheving's amazing stunts and talent as a gymnast, to the point where the character won't simply ''walk'' anywhere - instead he'll flip, somersault, walk on his hands, cartwheel, etc. just to get to wherever he needs to be. Granted, the show was created by Scheving himself, but still...
* {{Catchphrase}}: "Someone's in trouble!"
* ChestInsignia: Sportacus' "10".
* InnocentBlueEyes
* InvincibleHero
* KryptoniteFactor: Sportacus' is sugar; eating any sugary food renders him immediately comatose, and fresh fruit (which contain quite a bit of sugar.) or vegetables (a classification that includes a handful of "sugary" foods, most prominently the sugar beet) are required to restore him.
* LightningBruiser: Although since the show is aimed at pre-teens he never actually engages in violence.
* MrFanservice
* MundaneMadeAwesome: No matter the task at hand, Sportacus will make sure he does it involving at least a few backflips, twirls, and heroic poses... Even walking down the street.
* PinkGirlBlueBoy: With Stephanie.
* WeaksauceWeakness: he is crippled by eating chocolate, but can regain power by eating healthy foods.

* BlitheSpirit
* {{Catchphrase}}: "There's always a way!"
* CheerfulChild
* HairDecorations: She wears a pink headband in her pink hair.
* NaiveEverygirl
* NotAllowedToGrowUp
* PinkGirlBlueBoy: With Sportacus.
* PinkmeansFeminine: She has pink hair, wears a pink headband, and all her clothes are pink.
* PluckyGirl
* RoseHairedSweetie
* TokenHuman: Stephanie is the only human child, and the only female human, even though her uncle and every other townsperson is a puppet.
* TomboyAndGirlyGirl: The Girly Girl to Trixie's Tomboy

!!!Robbie Rotten
* AlliterativeName
* AmbiguouslyGay: Despite claiming to hate Sportacus and wanting him to leave the town, Robbie sure spends a lot of time talking about Sportacus, touching Sportacus and jumping into his arms whenever the slightly-above-average hero shows up.
* AntiRoleModel
* BadIsGoodAndGoodIsBad
* BigOlEyebrows[=/=]EvilEyebrows
* BrilliantButLazy: Robbie is the epitome of this trope. He prides himself in being lazy, and even schemes to make the rest of the town as lazy as he is, yet he is easily the most brilliant person in the entire town and is able to create ''anything'' out of ''anything''. Ironic, seeing that due to Robbie's constant attempts to make Lazy Town lazy via elaborate traps, machines, and costumes, he becomes one of the most active residents.
* CampStraight
* {{Catchphrase}}: "I meant to do that!"
* TheChewToy
* CreepyCrossdresser
* DastardlyWhiplash

* ExcessiveEvilEyeshadow
* GadgeteerGenius
* GrayEyes
* HarmlessVillain
* IneffectualSympatheticVillain
* LanternJawOfJustice
* LaughablyEvil
* MasterOfDisguise: He's even got a song about it!
* MrFanservice
* NamesToRunAwayFromReallyFast
* NotEvilJustMisunderstood
* PaperThinDisguise: Sometimes.
* {{Schemer}}
* SillyWalk
* VillainousCrossDresser: As Miss Roberta.
