Superego: Akame, who was trained from childhood to be the perfect assassin, and as a result shows little emotion while killing with ruthless efficiency.
Id: Kasumi Tomine — Joined because she likes catching/fighting aliens. Also contrasts with Yuri in that she is a prodigy and a xenophile. Also serves as the red oni to Kumi's blue.
Ego: Yuri Otani — Railroaded by her classmates since no one else wanted to be stuck wearing the Ugly Cute alien. The opposite of Kasumi in that she is a crybaby moeblob who despises all things alien.
Superego: Kumi Kawamura — Chose to be an Alien Fighter rather than be saddled with the higher pressure and responsiblity of Class President (little did she know...) but is also the thinker and The Stoic of the group. Also serves as the blue oni to Kasumi's red.
Id: Eren Yeager (The McCoy) — the brashest, most easily affected by emotions, and most eager to fight.
Superego: Mikasa Ackerman (The Spock) — a ruthless fighter, the calmest and most emotionally distant, able to be decisive where other would hesitate. Subverted, since this goes right out the window whenever Eren is concerned.
Ego: Armin Arlert (The Kirk) — Childhood Friends with Eren and Mikasa; hence he is able to calm Eren down and rationalize with Mikasa.
There's also Levi, Erwin, and Hanji later on:
Id: Hanji — emotional to the point of being creepy at times
Superego: Levi — cold and ruthless pragmatist, looks at things logically to the point of being a borderline Sociopathic Hero
Ego: Erwin — considers both emotions and doing what needs done to be equally important.
Finally, the Titan Shifter Trio
Id: Reiner who blows the cover of the Shifters due to emotional stress and develops a split personality due to said emotional problems.
Superego: Annie who is the coldest member of the group who hunts their enemies down with frightening persistence.
Ego: Bertolt who shows far more emotion than Annie, but is able to cope with the stress far better than Reiner.
Ego: Osaka — The slow, spaced out, oddball who may act naive, but is generally curious about things.
Id: Tomo — The rowdiest, hyperactive of the younger three, who constantly annoys her peers.
Superego: Chiyo — Despite being the youngest she's a Child Prodigy with an innocent, helpful mindset, of which she can very easily be upset.
The older trio:
Superego: Yomi — The Straight Man with a low tolerance for stupidity. She's either the most logical or the most manipulative of the group.
Id: Kagura — A heavy-handed Tomboy who has her tough girl moments from time-to-time.
Ego: Sakaki — The shy, tallest girl, who longs to be admired by cute creatures. She is very much a mystery to the other characters, which can look intimidating.
Superego: Keith Gandor — Oldest brother. The Quiet One and flat-out voiceless in the anime. Conservative thinking and adherent to ethics and tradition.
Id: Berga Gandor — The middle brother. Huge, emotional, and intimidating. Not very bright.
Ego: Luck Gandor — The youngest. The calm, collected "brains" of the group. Usually at the head in most of their dealings and serves as the mediator.
Berserk: It's downplayed, but this definatley applies to the main protagonists in the golden age arc.
Id: Guts — Impulsive, driven mainly by his emotions and will to survive, Book Dumb, tends to act first and think later.
Ego: Rentaro — Enju's partner who happens to be the balancer between Enju and Kisara. He is a Nice Guyutilitarian who is willing to help others in need and make everyone in his life happy. At the same time, most of his decision-making is very pragmatic.
Superego: Kisara — A cold Anti-Hero who wants revenge against her own family bloodline for being responsible for the deaths of her parents and willing to commit acts of evil to defeat a greater evil. After Tina Sprout joins, she fits into between the Id-Ego category.
The main villains of Hueco Mundo arc, all former Captains from the Soul Society.
Ego: Aizen — The serene, soft-spoken yet supremely arrogant leader. The other two are completely loyal to him, so he has no trouble keeping them in line
Id: Gin — Constantly grinning, utterly without empathy, and more than happy to start trouble. Had a reputation for recklessness and scheming even before Soul Society found out he was Aizen's minion.
Superego: Tousen — Calm and stoic, Tousen is a Knight Templar who believes following Aizen is the least violent way to bring order to the world. He prioritizes his personal code above all else, even if it means harming former friends.
The Freudian Trio/Platonic Tripartite Soul also applies to the first three members of the Five-Man Band and love triangle:
Superego: Rukia — Rational, calm, contemplative, self-possessed, driven by duty, conscientious to the point of being suicidal over something that wasn't her fault, and is the damsel in distress in the rules-obsessed Soul Society
Ego: Ichigo — The spirited protagonist and, as mentioned, is a tripartite soul himself with Ichigo proper, Zangetsu and Hollow Ichigo — lampshaded by the in-story "king and his horse" analogy which is similar to the charioteer analogy in Plato's Republic.
Id: Orihime — Appetitive, acts on her gut feelings and emotions, her unusual tastes in food are a running joke, and is the damsel in distress in Hueco Mundo where the inhabitants are driven to eat each other.
Ego: Touma — more compassionate than Accelerator but his Hot Bloodiness is more laid back than Misaka, with a power that is less impressive than the others, but slightly more practical and down to earth
Id: Vicious was arguably a superego, but either has become (or always was) the id, driven by an extreme lust for power and control. When interacting with others, he puts on the cold facade of a superego, but when he fights, he is animalistic and instinctual, though he favors a weapon of serenity and discipline.
Superego: Spike started as an id, but arguably was shifted to being a superego by Julia's influence and now more less abides by the law, remaining calm and never letting his emotions show. He has the tendency to lapse back into a more id like state when angered, but mostly is calm and content, exemplified by his combat style of non-aggressive redirection.
Ego: almost certainly Julia — while not as animalistic as Vicious and definitely in more control of her lust, she is still able to readily show emotions, unlike Spike
Ego: Ibuki is closer to Earth than Akagi, but is not always perfectly calm (manually activating Dai-Guard's Net Cannon by climbing out on the mecha's arm being one example)
Ego: Ryuk — Finds the others to be "so interesting."
The detectives
Superego: Near — Calm, cerebral and stoic
Id: Mello — Volatile, ambitious and passionate
Ego: L — The (im)perfect balance between the two
The factions that define the series:
Id: Death Note Owners — Mostly the instigators of the story, they normally start as morally sane people. Until the power they hold, starts to corrupt them.
Ego: The Shinigami — Supernatural beings with the power to kill, but are generally apathetic. Once they find an owner, they merely observe them until said owner dies.
Superego: Law Enforcement — Government-backed Lawmen such as the police, who try to solve the mystery of the growing number of deaths (being often led by a genius detective.) They are the main rivals of the Death Note Owners, attempting to bring them to justice.
Id: Miyako (Yolei) — the team's resident Genki Girl.
Superego: Iori (Cody) — Koushiro's successor in spirit, if not in abilities (since Miyako, unusually for an Id, is the tech girl for 02). He consciously tries to be as stoic and cool-headed as possible.
Ego: Hikari (Kari) — emphasised as the character of the purest heart in the series but also able to apply reason to her actions (it helps that like Takeru she's not new to this).
It's arguable that characters like Daisuke and Mimi have equally pure hearts, actually, since they tend to be optimistic and believe the best of people no matter what.
Dragon Ball Super establishes a potential trio of godly transformations:
Id: the Angels' Ultra Instinct technique, which allows the body to move purely on its own instincts and reflexes without conscious thought. Achieved by Goku, a carefree martial artist always known for going with his gut feelings rather than thinking. The Angels are also meant to train the Gods of Destruction, relating to how the id is described as being the driving force for the ego in psychology.
Ego: the Gods of Destruction's Ultra Ego technique, which contrasts Ultra Instinct by thriving on the user being fully conscious and self-indulgent about battle and the sensations involved with it. Achieved by Vegeta, an aloof warrior known for constantly fighting to sate his pride as a fighter and being envious towards Goku for being ahead of him. The Gods of Destruction themselves also have to make conscious decisions about what they do or do not destroy as a part of their jobs, relating to the ego's major role in psychology.
Superego: the Supreme Kais' Potential Unleashed technique, which gives the user access to all their latent, "ideal" potential at once, improving the skills and strengths they already have to their peak without the inhibitions that would hold them back. Achieved by Gohan, an educated prodigy known for being calmer, strategic and less driven towards fighting than either his father Goku or Vegeta. The Supreme Kais are also supposed to guide the mortal realm while having to follow certain limitations when it comes to directly interacting with them, relating to the superego's role in psychology.
Getter Robo tends to fulfill this with its pilot trios.
Id: Getter-1 pilots (Ryoma Nagare, Go Ichimonji, Takuma Nagare) — Hot-Blooded, aggressive, and violent, traditionally the best physical fighter.
Superego: Getter-2 pilots (Hayato Jin, Sho Tachibana, Show Takumi) — Intelligent, even-tempered, tactically-minded, highly pragmatic to the point of cruelty.
Ego: Getter-3 pilots (Musashi Tomoe, Benkei Kuruma, Gai Daidou, Baku Yamagishi) — Goodnatured, likeable, kind, and the most "normal" of the group.
Id: Azumane Asahi — the glass-hearted ace of the team who takes everything said to him to heart, easily gets insecure about his own skills, and shoulders all the guilt and blame — leading to him making rash decisions (such as leaving the team) influenced by his emotions.
Superego: Sawamura Daichi — the responsible captain of the team who is mature and patient but can also be terrifying as he is strict about how a team should behave and has certain expectations of his teammates.
Ego: Sugawara Koushi — the soothing and nurturing vice-captain of the team who acts as the pillar of support and has great understanding of how his teammates feel. He is the only one who can lecture Daichi and he is also highly perceptive of Asahi's emotions, acting as a mediator between them when Daichi acts too hard-headed about Asahi's insecurities and anxiety.
Superego: Natarle Badgiruel — Sergeant Rock. Firmly believes in the importance of discipline and abiding by military regulations.
Ego: Mu La Flaga — Veteran Ace Pilot who serves as a pragmatic midpoint between Murrue and Natarle, respecting military regulations while recognizing that some situations require flexibility. Maintains a balance between his natural inclinations toward being a good soldier and being a good person.
Id: Shinn Asuka — An idealist who doesn't realise he's in a show with Grey-and-Gray Morality. Impulsive, hotheaded, and loyal to his friends before all else; has a tendency towards blaming others whenever something goes wrong.
Superego: Kira Yamato — Technical PacifistAll-Loving Hero who suppresses his own strong feelings in the name of saving the world, putting his own emotions on the backburner in the interest of protecting others. Very, very focused.
Ego: Athrun Zala (leaning towards Superego) — A conflicted patriot who wants to believe to the same degree that Shinn does, but is too cynical and bitter after his experiences in the first war to implicity trust those around him. Wavers between following Shinn and Kira for much of the show, eventually settling on the latter.
The Minerva Trio (actually a great example of a failedPower Trio, in which the Ego is unable to successfully balance the other two, leaving the Superego in control, and the Id violent, angry, and on the verge of a confusion-induced nervous breakdown)
Id: Shinn Asuka — Jerkass WoobieHero with an F in Good. His heart's in the right place, but his Unstoppable Rage gets in the way of his doing the right thing. A wannabe hero who hasn't figured out that Black-and-White Morality just doesn't happen in Gundam. Suffers a mental breakdown over the course of the show as his desires and his gut instincts come more and more into conflict. Has a definite childish streak.
Ego: Lunamaria Hawke — Reasonable and friendly, she tries to be the mediator, but her lack of a forceful personality repeatedly sidelines her, allowing Rey more and more control over the group. She wants to do the right thing, but really isn't sure how to go about it, and her indicision has less than desireable consequences for Shinn in particular.
Phantom Pain
Id: Stella/r Louisier — Childish, in both good and bad ways; suffers from borderline paranoid schizophrenia.
Superego: Sting Oakley — Brother figure to his teammates and keeps the other two in control; cold, and the most practical of the three; the only one who knows when to call it a day.
Ego: Auel Neider (tending toward Id) — Ax-Crazy, but more "controllable" than Stella/r; has a brotherly relationship with Sting and is a Knight Templar Big Brother towards Stella (when he isn't emotionally abusing her).
Id: The Legislator. A lazy, lecherous layabout who prefers to drink and party than do his job, and frequently orders the Mononokean to pick up his slack whenever he lets too much of his work pile up.
Superego: The Executive. A stern Workaholic who almost never leaves his abode because he's so busy with work. He hates humans, but is willing to put aside his personal feelings if he understands that it's what's best for the Underworld. He served as Abeno's Tutor of all things Underworld when he's still just an employee, and begrudgingly accepts Ashiya's assistance investigating the curse.
Ego: The Justice. The Stoic but laidback individual who tends to mediate the conflict between the other two. He likes to go on his own pace, but unlike the Legislator, never leave his work unchecked.
My Hero Academia, of the main trio who intern under Endeavor together:
Superego: Nina — serious, stern, often at odds with Arika
Ego: Erstin — gentle and shy mediator between the two
Naruto has sixPower Trios (it helps all squads are in three and were probably made with this in mind): The squad will ALWAYS consist of Two Guys and a Girl , and usually, the two boys are Red Oni, Blue Oni when the girl is the Ego, but not always, like in Team 10, Ino is the Id instead of the Ego.
Pokémon Adventures has this with the trios of protagonists from Johto, Hoenn, and Sinnoh (The four Kanto protagonists are more of a Four-Temperament Ensemble, Unova has two sets of pairs, and Kalos' heroes are a Five-Man Band).
Id: Sanada Genichirou — Called the "Emperor", he's strong, ruthless, and has a tendencity towards violent reaction.
Superego: Yanagi Renji — The "Master", he is the team's data specialist, uses statistics and probabilities during tennis matches to predict the opponent's move, and crafts the team's strategies. Tends to be cool and aloof.
Ego: Yukimura Seiichi — Called "Child of God". Although he can be quite ruthless himself, Yukimura is the force uniting his team.
Ego: Madoka — the series is her being caught between the various things other people want of her. More to the point, she has a lot of cares, but doesn't tend to rush into things like her best friend, Sayaka.
Id: both Sayaka and Kyouko — hot-headed and following their impulses (very different though those impulses may be).
Ego: Normal Lain — Rational, has emotions, only personality Lain is fully conscious of
Id: Lain of the Wired — Self-destructive, impulsive, hedonistic
Space Runaway Ideon appears to have this in a less personified form than most:
Id: The Ideon itself — powered by the potentially infinite Ide energy (the name sounds like an eloquent enough clue) which is particularly triggered by threats to it and the youngest members of its crew, and sometimes acts on its own in those cases
Superego: The Solo Ship — Usually carries the more adult members of the cast, whom try to work toward everyone's best interest, and also the youngest children on board whom further emphasize everyone's resposability to keep everyone safe
Ego: Whomever's actually piloting the Ideon — Usually engaged in combat when needed, trying to keep the crew safe, but also needing to attack and thus making use of the Ideon's energy and its destructive power, a fragile balance that's usually hard to maintain
Id: Himeko is the former delinquent who tends to react to the wacky hijinks she comes across with explosive violence.
Ego: Bossun is the club's leader who can zigzag between silly and reckless and observant and cool.
Superego: Switch is The Stoic and The Smart Guy whose firm belief in pure science an logic frequently puts him at odds with the occultist, Reiko.
Soul Eater (Although they work separately most of the time)
Ego: Maka Albarn — The most equilibrated of the trio, tends to let herself be fueled both by her logic and her emotions.
Id: Black Star — Prefers to act before thinking in the results of what he is doing, by far the most impulsive of the trio.
Superego: Death the Kid — usually cold, smart and talented enough to face almost anything, however many times he lets his obsessive compulsive tendencies take control of him, this ironically from the fact he wants moral and physical perfection and balance, he is a god after all.
Id: Marik — mentally scarred, over-confident, revenge-driven and his plans involve and cause a lot of chaos and potential harm. Plus he has an Ax-Crazy split persona.
Ego: Ishizu — kind, composed and level-headed.
Superego: Odion — cold, stoic, polite and task-oriented.
The Doma Swordsmen:
Superego: Rafael — brooding, inexpressive, straightforward, tactical and does no more than what he feels is necessary.
Ego: Amelda/Alister — serious and strategic but also quite openly angry and distraught in his quest for revenge.
Id: Valon — always looking for a fight, lets his emotions drive his actions, and literally duels by punching his opponent.
The three non-filler villains:
Id: Marik — see Ishtar siblings.
Ego: Pegasus — Affably Evil, silly and childlike, yet also devises an elaborate scheme and calmly remains several steps ahead of his foes.
Ego: Zigfried — effeminate, outwardly calm and plans his scheme thoroughly, yet is also a Smug Snake who is Driven by Envy and becomes enraged when pushed hard enough.
Superego: Dartz — eternally composed, spends 10,000 years on his plans, anonymously remains behind-the-scenes nearly the entire time and manipulates both his allies and his enemies to his benefit.
Yu-Gi-Oh! GX Obelisk Blue Three Geniuses Trio, in the flashback:
