-->'''Alastor:''' Smile, my dear! You know you're never fully dressed without one!

* [[{{Shinigami}} Ryuk]] from ''Manga/DeathNote''. [[SlasherSmile It's creepy]]. He only broke it once when Light snapped at him after [[spoiler:offering the eyes after meeting L]].

* Gretchen from WesternAnimation/{{Recess}} (partially due to her large buck teeth) fits a rarely explored SurprisinglyRealisticOutcome version of this trope as she has a very pronounced lisp or some other kind of speech impediment that indicates excessive saliva.

* ''Anime/HelloSandybelle'': Sandybell is a GenkiGirl who doesn't let her father's death get in the way of her finding happiness in everything.

* Alastor from ''WesternAnimation/HazbinHotel'' nearly always wears a razor-fanged CheshireCatGrin, and in the rare exceptions, he's still smiling, just with his mouth closed. There is seemingly no moment in the pilot or the first season when he's shown not smiling, although it may come across as a bit of a grimace during some of the few times when his phenomenal composure cracks. Justified since he believes that smiling shows dominance and he has a reputation to keep, being one of the most powerful entities in all of hell.

* Alastor from ''WesternAnimation/HazbinHotel'' nearly always wears a razor-fanged CheshireCatGrin (and in most of the ''very'' rare exceptions, he's still smiling, just with his mouth closed). Justified since he believes that smiling shows dominance and he has a reputation to keep, being one of the most powerful entities in all of hell.

* Alastor from ''WesternAnimation/HazbinHotel'' always wears a razor-fanged CheshireCatGrin. Justified since he believes that smiling shows dominance and he has a reputation to keep, being one of the most powerful entities in all of hell.

* Konata Izumi from ''Manga/LuckyStar'' is a downplayed example; her default expression is a mischievous CatSmile, but she does openly show other emotions as well.
* ''Anime/LucyMayOfTheSouthernRainbow'': Kate always has a mischevious CatSmile on her face and is a prankster, while Lucy-May is a CheerfulChild.

* Popuko and Pipimi from ''Manga/PopTeamEpic'' have permanent [[CatSmile :3 faces]] no matter what emotion they're feeling. This is especially noticeable with Popuko, who regularly flies into a [[AxCrazy violent,]] [[TroublingUnchildlikeBehavior profanity-filled]] rage over extremely trivial things, smiling the whole time.

A StepfordSmiler would be a sub-trope, one who smiles because that's all they can do to keep from ''breaking''. A CatSmile or CheshireCatGrin can also be their perpetual expression. A rarely explored SurprisinglyRealisticOutcome version would depict a character with a lot of saliva in their mouth, because it's honestly impossible (or very hard) to swallow one's own saliva while literally always smiling, making even a genuinely sweet smile go from sweet and charming to [[AccidentalNightmareFuel potentially terrifying]] or at the very least disgusting. A Perpetual Smiler's smile can change, and the emotions behind it can be literally anything, so long as there is something that can be called a 'smile' on their face. Usually, though, this smile is pleasant and cheerful, or at least calm, and often, the feeling behind it is genuine, so TheUnSmile doesn't usually appear. Compare FrozenFace if they literally can't stop smiling and to GlasgowGrin where the smile is ear-to-ear and usually inflicted by cutting.

* ''Literature/TheExpanse'': SociopathicHero Amos sports a vague amiable smile as his default look, even when he's seconds away from smashing someone's face in. His POV chapters reveal that it's a deliberate affectation he picked up because he noticed it tended to put people at ease and make things go more smoothly (though, thanks to his unspecified mental disorder, he's not entirely sure *why* it does). People who know him well tend to find it a bit unsettling because they know that the smile reveals precisely nothing about what's going on inside his head.
* Itsuki Koizumi from ''Literature/HaruhiSuzumiya'' is almost never seen without a smile. Even in ''The Surprise of Haruhi Suzumiya'' when [[spoiler:Fujiwara threatens to kill Haruhi, Koizumi continues to smile even though [[BewareTheNiceOnes he's clearly pissed off.]]]]

* ''Anime/LucyMayAndTheSouthernRainbow'': Kate always has a mischevious CatSmile on her face and is a prankster, while Lucy-May is a CheerfulChild.

* Dr. Paula "Hutch" Hutchison in ''WesternAnimation/RockosModernLife''.

* Hazama, [[Manga/{{Bleach}} Gin Ichimaru]]'s {{Expy}} from ''Franchise/BlazBlue'', seems to be this.

* Bobble Hat from the ''[[Manga/{{Splatoon}} Splatoon]]'' [[Manga/{{Splatoon}} manga]], being ThePollyanna and GenkiGirl, always sports a huge smile on her face alongside [[EyesAlwaysShut closed eyes]]. In fact, the only way you can tell her emotions is her eyebrows, as she does sport an angry pair of eyebrows in one chapter after her team loses to an off-screen match against Skull and the Purple Team.

* Alastor from ''WebAnimation/HazbinHotel'' always wears a razor-fanged CheshireCatGrin. Justified since he believes that smiling shows dominance and he has a reputation to keep, being one of the most powerful entities in all of hell.

* Bill Cipher from ''WesternAnimation/GravityFalls'' has no mouth in his pyramid form, but his affable demeanor suggests this. When [[spoiler: he possesses Dipper's body]] and gains a mouth in "Sock Opera", it spends most of the time in a grin that ranges between "cheerful" and "[[SlasherSmile psychotic]]".

* Yes Man from ''VideoGame/FalloutNewVegas''. He was originally a securitron like the ones patrolling the New Vegas Strip, but one day he was reprogrammed to work as a sort of assistant for a businessman named Benny. When he was reprogrammed, he was given the unique personality of a yes-man (hence the name), which means he was coded in a way that makes him completely unable to say no. He will react positively to everything the courier does, which sometimes leads to some passive-agressively positive quotes coming from him, and even some that could easily qualify for a StepfordSmiler.

* ''WesternAnimation/TheSuperMarioBrosMovie'': Lumalee has a smile on his face even when he's talking about wanting to die. The only time he frowns is when he [[spoiler:is almost killed but gets saved, and when he's talking to the audience at the end]].

* Ling-Ling from ''Manga/RosarioPlusVampire''. Justified, since she's [[CatchPhrase already dead]], and thus has nothing left to worry about.

* The eponymous ''WesternAnimation/RubyGloom'' since she [[CatchPhrase always looks on the bright side]] -- in direct contrast to her aptly-named friend Misery.
