* ''Fanfic/Swing123AndGarfieldodiesCalvinverse'' has something akin to this in a sextet:
** Calvin and Socrates are the Ids, the latter more so.
** Hobbes and the MTM are the Egos.
** Andy and Sherman are the Superegos, the latter more so (again).
* [[TheMcCoy Mello]] (the Id), [[TheKirk Matt]] (the Ego), and [[TheSpock Near]] (the Superego) from ''Fanfic/ConstantTemptation''.
* Takato, Ruki and [[spoiler: Chaos]] all form one of these in the ''FanFic/TamersForeverSeries''.
** TheId: [[spoiler: Chaos]], the living embodiment of disorder and thus the most impulsive of the trio.
** SuperEgo: Ruki, a sentient A.I and thus the most intellectual of the three.
** TheEgo: Takato, the balance between the two.
* There are two sets in ''FanFic/AkatsukiKittenPhoenixCorporationOverhaul'', working under the author:
** The three main girls: Goldstone (the Superego), Diamond (the Id), and Opal (the Ego).
** If we go with the three highest rankings, however: Goldstone (the superego), Opal (the Id), and Chimera (the Superego). The author implies that Opal and Chimera used to be reversed, however.
* There are a lot of freudian trios in ''FanFic/SuperSmashBrothersGuardiansArise'', considering that a lot of chapters introduce three characters at the same time. Some examples being:
** [[TheID Aly]] (The Id), [[SuperEgo Eric]] (Super Ego) and [[TheEgo Mars]] (The Ego).
** [[TheID Nao]] (The Id), [[SuperEgo Kai]] (Super Ego) and [[TheEgo Teal]] (The Ego).
* In ''FanFic/{{Horseshoes and Hand Grenades}}'' and its subsequent sidestories have characters in different groups at the same time. This includes:
** Rumi (the Id), Jun (Superego) and Mari (Ego)
** Ibuki (the Id), Taira (Superego) and Abe (Ego)
** Yuki (The Id), Miu (Superego) and Tomoko (Ego)
** Yuki (the Id), Erin (Superego) and Tomoko (Ego)
** Jiro (The Id), Gentaro (Superego) and Kengo (Ego)
* Subverted in ''FanFic/FirstTrySeries'' with Team 7. Kakashi tried to see them as this, thinking they mirrored his own team but is dead wrong. Naruto hates both his teammates, Sasuke is anti-social and abrasive and Sakura sides with Sasuke no matter the situation. So basically Sasuke is TheSpock but there is no "[[TheMccoy Mccoy]]" or "[[TheKirk Kirk]]" to keep him in check.
** In ''Legacy Of The Rasengan:'', Naruto tends to alternate between TheKirk, TheMccoy and TheSpock which tends to throw the team dynamic off what with Sakura being TheMccoy and Sasuke being TheSpock. Makes it very complicated since Naruto has to, at times, play a one-man FreudianTrio to get the team to work on any level.
* In Lauralot's [[http://www.fanfiction.net/s/5085463/61/Shadow-Selves Shadow Selves]] fic, Scarecrow and Jonathan are written as a "functional" version of dissociative identity disorder. Chapter 61 reveals that Jonathan works as the superego of their team while Scarecrow acts as the id - and Scarecrow "had no idea where their ego was". In a more traditional sense, the author mentions that they recorded their psych notes as Superego: Batman, Joker: Id, and Ego: Bruce Wayne.
* ''Fanfic/EmpathTheLuckiestSmurf'': The PowerTrio of the three BadAss Smurfs: Tuffy (the Id), Duncan [=McSmurf=] (the Superego), and Hefty (the Ego).
* In ''Fanfic/NecessaryToWin'', there is one such trio among three students of the Nishizumi school. Kikuyo is TheMcCoy, a compassionate and idealistic maid for the head instructor, who [[ConflictingLoyalty is torn between her loyalty to her mistress, and her desire for the well-being of her mistress' daughter]], to whom she is [[ParentalSubstitute a mother figure]]. Ami Chouno, a JGSDF instructor who helped train Oarai's tankery team, is TheKirk, who shares many of Kikuyo's desires and conflicts, but also reminds her of practical considerations. Takako Kubo, who, in this fic, is Black Forest's coach, is TheSpock, believing that [[DrillSergeantNasty harsh methods of discipline]] are [[IDidWhatIHadToDo entirely justified and necessary]] in order to make Black Forest a winning team. Interestingly enough, TheSpock in this case gets along with TheMcCoy better than TheKirk, with whom she had a falling out over her methods of discipline.
