Another sliding scale like Sliding Scale of Idealism vs. Cynicism. Where characters are plotted on this line depends on how emotive they are.
Positions on this scale aren't static; characters shift with their moods but can still be placed by their baseline.
If he's not smiling, is he sad or is that his normal face? If he is smiling has something good happened, or is he just a happy person? Enthusiasm overlaps with discord, change or denial.
Stoicism parallels continuity, repression, and law. Everyone feels, so the criterion is how much they display the emotion. The brooder who'll betray the friends he secretly hates is stoic (however great his wrath). Manipulators are stoics because they're suppressing their genuine emotions to display fake ones.
- Kazuhiko Shimamoto's works. His characters are Hot-Blooded, prone to suddenly bursting into tears, exploding into rage or cheering wildly and they Never. Stop. Sweating.

- Great Mazinger: Tetsuya Tsurugi.
- UFO Robo Grendizer: Duke Fleed.

- Gaiking: Sanshiro Tsuwabuki.
- Raideen: Akira Hibiki.
- Combattler V: Hyoma Aoi.
- Voltes V: Kenichi Go.
- Daimos: Kazuya Ryuuzaki.
- Zambot 3: Kappei Jin.

- GaoGaiGar: Guy Shishioh
- Tengen Toppa Gurren Lagann Simon
- Great Teacher Onizuka: Onizuka-sensei.
- Samurai Champloo
- The Brothers Karamazov: Most characters are bursting with feeling. Their conversations end up in hysterics.
- In Galaxy of Fear Tash and her uncle Hoole are both intelligent and like to research things, and particularly by the end of the series they both tend to know something about wherever they've gone and whatever they're seeing. But while Tash tends to be enthused and animated about it, Hoole is known for being The Stoic, even when he's very interested in something. Tash's brother Zak is Book Dumb and is similarly more inclined to showing emotion.
- Final Fantasy VIII: Selphie Tilmitt is a Genki Girl with some bloodthirsty streaks. Zell Dincht is just really loud and doesn't stop moving.
- Sonic the Hedgehog: Sonic when he gets worked up, Knuckles all the time.
- Rouge, as an anti-hero-ish variation.
- Mass Effect 2: Kasumi Goto.
- Onion Knight, Tidus, Barts and Zidane (to the extreme) Prishe, Laguna Loire, Vann, and Tifa on the heroic side for Dissida.
- Kuja, Jecht, and Kefka on the villainous side in Dissidia Final Fantasy.
- Octopus Pie: Hannah Thomspon is giddy, angry or something. There is no calm.
- X-Men's Cyclops. Renowned for his stiffness and abnormal self-control (paired with his ironically uncontrolled eye-beams he can't turn off).
- While it might seem like his tight self-control is the result of dealing with being unable to control his destructive mutant ability, it was at one point revealed that his inability to control it was a subconscious decision he made as a child out of guilt for being unable to save his family (or even accidentally making the situation worse when their plane was crashing)
- There Will Be Blood: Plainview smolders with hatred for humanity he fights to contain. He leaves a town with oil reserves because the populace is too disorderly. He walks away from his son without a word when delivering him to a school for deaf people. Eli has to work him up to a yell in the Church of the Third revelation because Plainview's used to restraining his emotions and talking in conversational levels. Stoicism has clearly taken a hike by the end of the film.
- Half Baked: The guy on the couch. Steven Wright has made a comedy career out of his unnaturally mellow stage persona.
- Final Fantasy VIII: Squall Leonheart and this is a constant source of conflict throughout the game.
- Shadow of the Colossus: Though you're Their only present chance of freedom, Dormin is mellow.
- Shadow the Hedgehog. Unless he's angry, because then he becomes a raging psychopath.
- Cloud, Squall (on par with his Final Fantasy VIII persona), and Lightning on the heroic side, and Sephiroth, The Cloud of Darkness, and to an extent Golbez on the villainous side of Dissidia Final Fantasy.
- Joe Musashi, all the time.
Works With This Scale as a Theme:
- Code Geass is exceptional; Lelouch hides his humanitarian motivation to be the villain he thinks people need.
- Mobile Fighter G Gundam, generally an enthusiastic series as shown above, includes Meikyou Shisui, Clear Mirror Still Water, which requires the user to channel both enthusiasm and stoicism at once.
- Many manga and anime, particularly shounen series, implicitly contain this scale as a theme because the characters must reach ever-greater emotional extremes to power-up but control their emotions to limit the area-of-destruction to enemies.
- The Dark Knight: The Joker wants to destroy peoples mind-numbing plans, the routines of job and duty, so they'll wildly grapple with the pointlessness of existence.
- Coffee and Cigarettes: The opening sketch airs terminally lethargic Steven Wright with hyperactive Roberto Benigni — switching their characters.
- In the Star Wars universe, the two sides of the force each represent one end of the sliding scale with the Dark Side being the enthusiastic, yet murderously evil end, and the Light side being the well intentioned, disciplined end.
- Warhammer 40,000, where Chaos feeds off of emotion (the four main gods embody rage, desire, love and hope) and ruthless stoicism is the main alternative. Go too far on the scale and you get the Necrons, sentient robots who exist only to destroy life and serve the literal Grim Reaper. Did we mention the Grim and Dark future is not a nice place?
- The Elder Scrolls IV: Oblivion: In The Shivering Isles, those blessed by Sheogorath with Dementia may emote but rely more on keeping their feelings secret, the better to surprise enemies with. Maniacs lose themselves in sensation.
- Whenever Shadow tends to be paired up with any other character in the Sonic cast (Sonic and Rouge being good examples) he's usually the more serious of the pair. While Rouge invites him to go treasure hunting with her, he completely rejects the idea and wants to stay focused on the main mission. When he and Sonic team up briefly in Shadow the Hedgehog, he's annoyed at how much fun his blue counterpart is having.
- Final Fantasy absolutely LOVES this trope.
- In Final Fantasy VIII, this trope is epitomized by Rinoa and Squall (Enthusiasm and Stoicism, respectively) and is a big source of conflict between them.
- In Dissidia Final Fantasy, this happens for both the villains and the heroes. The previously mentioned Squall ends up teamed with Zidane and Bartz. Hilarity Ensues.
- Also, Cloud is the more quiet of his gang of four, which just happens to include Tidus. Again, Hilarity Ensues.
- Lightning from Final Fantasy XIII is a Stoic who has to put up with an entire team of Enthusiasts, composed of Tifa, Laguna, Vann and Yuna, who are all fairly optimistic and enthusiastic. She snaps at Laguna and Vaan constantly for their optimism and carefree natures. That said, she at least has fellow Stoic Kain for company.
