Ickis: Main character, ability to scare by growing to tremendous size is affected by his confidence which varies greatly depending on outside influence. (Ego)
Krumm: Slothful, gluttenous, rife with body odour and with all the other flaws of unrestrained children. (Id)
Oblina: Smart, motivated and studious, often trying to get the other two to pull themselves together. Kind of like if Hermione Granger was a black and white talking candy cane. (Superego)
Also the original Gaang before they picked up Toph:
Sokka: Bossy, Deadpan Snarker, rigid , enjoys planning, try turn into the leader of the group noting the obvious clumsiness of Aang. (Superego)
Aang: Avatar or not, he is to all the effects a hiperactive, playful and mischievous kid and acts more by emotion than logic and is The Messiah to boot. In the start, also was a bit of a Cloud Cuckoolander. (Id)
Katara : Acts more by emotion than logic, but less than Aang. (Ego, leaning to Id)
Vinnie: Fun-loving party animal and wise-cracker, who acts first and apologises later. Always has a grin, even when in pain. Colour scheme: white. (Id)
Modo: Preaches traditional moral values and quotes the wisdom of his grandmother. Gentle-hearted giant whose anger is usually brought on by reflecting on the actions of others. Chooses to wait and plan rather than rushing in. Colour scheme: grey. (Super ego)
Throttle: Cool, wry, with a soft-spot and great understanding for his bros, but with a keen eye for the middle ground between them. Warm-hearted and fun-loving, but in moderation, and serious and commanding as the situation demands. He will generally hold the veto vote between the paths of action suggested by the two extremes. Colour scheme: yellow (Ego)
Eddy: Schemer, the leader, ruled by his desires (Ego)
Depending on the nature of the episode, they sometimes switch roles: Rules-obsessed Edd can become the limiting Superego, while Cloud Cuckoolander Ed can act as the Ego. Ironically, when this happens, it puts no-self-control Eddy in the Id position by default as he tries to reign in the extreme behavior of the other two and keep them focused on their goal (jawbreakers or money.)
Futurama:
Jimmy: Fun-loving, optimistic, often tries to make peace between Beezy and Heloise; but can think before he acts, often oblivious to faults of others. (Ego, with some Id and Superego qualities)
Beezy: Lazy, a glutton, and doesn't follow his father's steps. (Id)
Heloise: Intelligent, only calm around Jimmy and looks out for him due to her crush, but is easily angered, sadistic, and tries hard to be nice (Superego with some Id and Ego qualities)
Korra: A brash and impulsive Destructive Savior who likes to pick fights and often acts before she thinks things through. (Id)
Mako: A serious Control Freak who keeps his life in strict order and focuses intensely on his goals, out of fear of being turned back out on the streets. (Superego)
Bolin: A laid-back charmer who loves a good time and good laughs, but isn't afraid of hard work. (Ego)
Coop - Impulsive Genius Ditz, usually the one to get them in trouble. Id.
Kiva - Always trying to hold Coop back from his id-riffic rampages. Superego.
Jamie - A fairly normal guy (if unambitious), although he isn't completely immune to flights of fancy. At the very least, he sometimes tries to talk Coop out of his more dangerous exploits, in favor of going to look for the Planet Of Hot Amazon Women. Ego.
Twilight Sparkle: Intellectual, driven, conscientious, principled, and dutiful, but also obsessive compulsive, and at least initially cold and impersonal. (Superego)
Rarity: Driven, ambitious, orderly, meticulous, and also can be obsessive-compulsive. (Also superego)
Applejack: Responsible and sensible. (Ego)
Fluttershy: Also generally responsible, and tries to mediate conflict within the group, and in general. (Also ego)
Rainbow Dash: Brash, arrogant, voluble, but also lazy and prone to selfishness. (Id)
Harvey Dent: normal personality that is timid and easily bossed around (ego)
"Big Bad Harv": violent criminal made from years of repressed anger (id)
The Judge: violent vigilante obsessed with justice (with a court-theme to match) that ultimately plans to kill his bad side (i.e. 'himself''), probably created by guilt from normal side (superego)
The Cowlarado Kid: Impulsive, lively, ruled by his heart and sexual urges, often prone to wild leaps of fancy. (Id)
Dacowta: Slow and steady, extremely level-headed and serious traditionalist. (superego)
Marshall Moo Montana: Warm-hearted and fun-loving, but in moderation, and serious and commanding as the situation demands. Fulfills the Captain Kirk role. (Ego)
Interestingly, this trio adopts a colour scheme for each character: yellow for the neutral Marshall, cool grey for Dacowta, and warm cream for Cowlarado. This scheme is revisited in Biker Mice from Mars...
