Berserk Button: When he returns to Pride Rock after Scar turns it into a barren landscape, he snaps when he sees Scar striking his mom.
Big "NO!": When he witnesses his father fall to his death.
Brains: Evil; Brawn: Good: In his conflict with Scar. Though it's shown in the sequel that, while not perfect, he manages to turn the Pridelands around and is a far more competent ruler than Scar, who had no idea what to do with his power.
Former Teen Rebel: As an adult Simba becomes strict and judgmental and takes his job of ruling the kingdom very seriously, even though he used to be a Bratty Half-Pint.
The Good King: Like his father before him, he manages to make the land flourish unlike Scar.
Hates Baths: As a cub. Possibly the main example from Disney.
Held Gaze: Simba and Nala gaze deeply into each other's eyes at the end of their Falling in Love Montage of "Can You Feel the Love Tonight?" before nuzzling each other in a manner that resembles a kiss.
The Hero: The first movie is about his growth and life.
Heroic BSOD: When he thinks he's the one who killed his father.
Heroic Second Wind: Scar nearly backs him off of Pride Rock while he's trying to guilt-trip him. But just as he's about to push him off to his death, he admits to being the one who killed Mufasa. Needless to say, Simba pounces on him in a instant and starts choking him to get him to admit the truth.
He's Back: The reaction from his mother, Scar, and the other Pridelanders.
Mouthy Kid: So much, at the beginning of the movie, especially towards Zazu.
Overprotective Dad: Very much in the sequel. Like other overprotective Disney parents, though, he has good reason. Still, he goes overboard.
Parental Hypocrisy: At one point, Nala points out to Simba that Kiara's just like they were when they were cubs, and Simba explains that this is what worries him.
Perfectly Arranged Marriage: He and Nala both balk at the idea of getting married—at first, while they're still cubs. After they grow up...
Rebel Prince: After Mufasa's death and Scar's manipulation, he goes into exile and shakes all responsibility as rightful successor to his father's kingdom. He eventually returns years later when he is informed by Nala how bad things have gotten under Scar's misrule.
Warrior Prince: Takes charge of the battle to reclaim Pride Rock and faces Scar in one-on-one combat.
"Well Done, Son" Guy: Although anything but an emotionally distant father, Mufasa is often preoccupied with the duties of the throne, and little Simba certainly sees him as a hero, worshiping the ground his paws tread upon. But there is no indication Simba ever doubts he has his father's love or respect...until Scar convinces him he is to blame for his father's death. Then, overcome with remorse and believing no one could ever forgive him, he voluntarily goes into exile. It is Mufasa's ghost, reminding him of his place in the Circle and telling him "You are my son and the one true king," that sets him back on the right path again. And with a simple, single word, "Remember..." he lets his son know he is very proud of him indeed.
However, has Simba forgetting this moving testimonial and unable to get over his past, refusing to trust Kovu or see him as anything but a reincarnation of Scar, all in the mistaken belief that this is what his father would do (and therefore, would make Mufasa proud of him). Luckily Nala, as usual, is the voice of reason while Kiara, with typical bluntness, makes it quite clear to her father that he is not and never will be Mufasa. And just to hammer the point home that Simba does not have to emulate his father's reign (or his perception of it) in order to receive his love and pride, Mufasa's ghost actually says the words, "Well done, my son" after the prides are united and peace is declared.
You Killed My Father: After Scar admits that he is the one who killed Mufasa, Simba forces him to reveal the truth to the other lions.
"As king, you need to understand that balance, and protect all the creatures, from the crawling ant to the leaping antelope."
The Farmer and the Viper: Mufasa learns the hard way in that being nice to an Obviously Evil sibling, who was scheming right behind his back, isn't going to change his heart. And not even entirely behind his back. Scar all but announces on the day of Simba's presentation that he hates the new cub, wants the throne, that Mufasa should beware of him, and that he won't attempt to seize it by challenging him directly.
Fatal Flaw: He did seem overly trusting of his brother...
Framed for Heroism: Scar made it look this way to Simba when Mufasa's death was because of his attempt to rescue the cub.
The Good King: It's telling that all of the Pridelands (even the animals that are essentially food) come to the presentation of his son. The animals do not want, are happy, and respect him and he respects them back.
Bad Boss: Lets the hyenas run rampant over the Pridelands until even they run out of food, casually manipulates all of them into helping his selfish scheme and ultimately tries to pass the blame onto them when he tries to weasel his way out of justice.
Berserk Button: Mentioning how much better of a king Mufasa was than him, probably because he knows it's true. He can't stand hearing Mufasa's name, to the point that he makes a law against saying it.
Big Bad: Of the first movie. Killing Mufasa and ruining the Pridelands.
Big Bad Friend: Towards Mufasa and Simba, who only think of him as their loyal brother and uncle, respectively.
Bigger Bad: In 1 1/2, where the main conflict is essentially the same of the first movie, but because they're telling from Timon and Pumbaa's point of view, the primary villains are the Hyenas, and Scar's machinations serve only as the background.
Bond Villain Stupidity: Subverted when he orders his hyenas to kill Simba instead of doing the job himself, as he told him to exile himself from the Pride Lands before doing so.
Brains: Evil; Brawn: Good: Zig-Zagged. He certainly is a great deal more fond of using manipulation and cunning to get what he wants, and he's very talented at both of these things. In addition, he admits that he is physically far weaker than Mufasa. When it comes to actually ruling a kingdom, however, he has no idea what he's doing, and the Pride Lands turns from a lush savannah to a barren wasteland in a matter of a few years. Upon Simba's return, however, he shows himself to be no less adept at the cunning manipulation that got him into power...and this trope is played with again when Scar proves himself to indeed be a viciously competent (if dirty) fighter when he's got no other options.
Simba: Uncle Scar, when I'm king, what will that make you?
Scar: A monkey's uncle.
Despotism Justifies the Means: Quite happy to let the Pridelands go to hell in a handbasket if that means he can be King. He's also pretty upfront that he wants the job for the power and refuses to even acknowledge that he's supposed to have duties and responsibilities to go with them.
Evil Sounds Deep: Scar carries a subtle reverb in his voice that becomes noticeable whenever he is dripping with sickly-sweet sarcasm or completely loses control of his temper. Of course, his voice is considerably less deep than Mufasa's...
Evil Uncle: To Simba, whom he tries to kill to get rid of Mufasa's sole heir.
Evil Will Fail: His plan turns out this way. He succeeds in becoming King, but the once-bountiful Pridelands quickly goes downhill under his disastrous and self-serving leadership. Even the hyenas think that Mufasa's reign was better for them.
Faux Affably Evil: Sure, he has no problem in murdering his own brother in cold blood to obtain the throne, but he still puts up a polite and suave facade.
Fisher King: Scar turns Mufasa's lush and green Ghibli Savanna into barren, dry, dead Mordor. Justified in that he allowed Hyenas into said lands, who over-hunted with the lions restrained by Scar from keeping them in check. Fewer grazing animals from overhunting means more leftover vegetation, more vegetation means more fuel for brush fires once the dry season sets in. One spark from lightning and the whole savannah could go up, and apparently did.
Genre Blindness: He sends his bumbling minions to kill someone whom they've already failed to kill, and just look at the results of the aforementioned Evil Gloating.
Good Is Dumb: Averted. Despite his claims, Scar actually is no smarter than his brother, yet is resentful that Mufasa gets to be King instead of him. When he finally does become King, it becomes clear he is not as smart as his brother; Scar is a lazy hedonist who isn't even interested in maintaining the Pridelands.
Green Eyes: Of the villainous sort - and figurative, as the following entry shows.
Green-Eyed Monster: Several lines in "Be Prepared" imply how jealous he is of Mufasa's success as king and the "injustice" that he's no longer next in line for the throne after Simba's birth. Heavy emphasis on the "monster" part. He's a literal example as well, since he really does have Green Eyes. Also notice that, in Real Life, lions don't have green eyes, making the use even more metaphorical.
A Handful for an Eye: During the final battle between himself and Simba, Scar kicks it off by throwing burning embers into Simba's eyes.
Jerkass: Truly exemplified when he murdered his own brother and blamed his death on his nephew.
Karmic Death: Survives a fall off of Pride Rock only to be eaten by his own hyena minions, who overheard him blame everything on them.
Kick the Dog: So many times, but the moment when he strikes Sarabi for standing up to him really stands out.
Knight of Cerebus: The film begins quite cheerful, but when Scar kills his own brother and takes the power, the film definitely becomes quite dark. Really, it gets really dark right when we get to his Villain Song.
Large Ham: In true Disney villain fashion. Producer Don Hahn even said part of Scar's hilarity is due to Irons adding disdain\insanity to lines that could be delivered straight.
Manipulative Bastard: One of the classic movie examples and fitting for a villain in a Shakespearean-style film. There are very few characters in the story whom he does not deceive, and he sometimes manipulates others purely for his own amusement.
Not-So-Harmless Villain: Let's see, Scar KILLS MUFASA, and is perfectly able to go toe-to-toe with Simba in the climax. A bit out of place considering that he groans about getting the brains and none of the brawn in the beginning, but makes some sense when you consider that Simba has apparently lived only on insects and has been in a total of one fight (that he lost). This plot point makes even more sense when taking into account Scar's original character design as a much more bulky and brawny lion.
The Sociopath: Has zero qualms over planning the deaths of his family and pretending to be racked with grief.
Psychopathic Manchild: Best exemplified by his "I am the King, I can do whatever I want" excuse, because it is essentially the attitude of Simba as a cub, even though Simba never meant it in such a bastardly way.
Pyrrhic Victory: His original fate in the Alternate Ending. He wins the fight with Simba by throwing him off Pride Rock, but is then burned to death himself when the fires surrounding Pride Rock engulf it. By throwing Simba off Pride Rock, he actually saves Simba from suffering that fate and allowing him to have his happy ending anyway, making Scar's victory in the fight meaningless.
Red Right Hand: His scar, and his claws that are always bared (unlike the others).
Sanity Slippage: More obvious in the musical, but still visible in the movie. The musical has a number called "The Madness of King Scar," where he begins to go completely insane.
Sanity Slippage Song: "The Madness Of King Scar" in the musical version. He grows more insane as the song goes on, eventually seeing the ghost of Mufasa everywhere and becoming desperate to have cubs to continue his line. He also becomes increasingly paranoid, believing that the lionesses hate him (which they probably do) and are plotting to murder him.
Smug Snake: After becoming king. Although Scar was a master of manipulating everyone around him to seize the power he craved, he proved to be utterly incompetent at actually using the power once he had it, though this was more due to laziness and selfishness than a lack of intelligence. He hadn't been raised to be a king so he had no experience. Like Simba as a cub, he thought that it was just all about the power and the glory rather than actual hard work. He'd originally persuaded the hyenas to support him by promising that they'd never go hungry again, but the drought in the Pride Lands leads to a famine and causes the hyenas to begin grumbling about Scar even before Simba comes back.
The Unfavourite: Well, considering that his parents gave him a name that means "wanting" and gave his brother a name that means "king," it's pretty clear who was their favorite... Subverted in the books, where he thinks he's this but it's shown his parents actually do care about him.
"The Madness of King Scar" in the Broadway musical version, a song that really focuses on his shift from Magnificent Bastard to Smug Snake in his reign as king.
The original ending of the film had a far more pronounced one. After his fight with Simba, which ends with Simba being the one thrown off Pride Rock (but lives), Scar is last seen laughing insanely as the fires surrounding Pride Rock engulf and kill him.
Villainous Legacy: His influence is still felt after his death, since the primary villains in the sequel are his sympathizers wanting revenge.
Villain Song: "Be Prepared" were he explains to the Hyenas how he intended to murder his brother and nephew to become king. There is also a cut reprise to "Be Prepared" were he introduces the Hyenas as his 'executive staff.'
Wanting Is Better Than Having: After killing Mufasa and finally becoming the King of Pride Rock, he ends up turning the paradise to ruins. Scar is obviously too proud to admit that he wasn't cut out for the job.
Wicked Cultured: Not only his speech is the more refined in the movie, but somehow he knows about the gene pool.
The Heart: Best shown when she tries to inform Simba of what has happened to their home.
Held Gaze: Simba and Nala gaze deeply into each other's eyes at the end of their Falling in Love Montage of "Can You Feel the Love Tonight?" before nuzzling each other in a manner that resembles a kiss.
Herald: Nala revealing to Simba what happened after Scar took over the Pridelands is the first step to get him to return home.
The High Queen: Since she is Simba's mate, Nala is technically the Queen of the Pridelands.
Birdcaged: What Scar does to him when he takes over, apparently just because he doesn't like him.
Butt Monkey: Starts out as Mufasa's PR guy and constantly finds himself at the butt of Simba's antics. After Scar takes over, he is reduced to a court jester and is almost eaten by the hyenas on several occasions.
Hakuna Matata: Trope Namer. Timon and Pumbaa tell Simba, who has just run away from his responsibilities and his life, that he doesn't need to worry about the past, because a carefree existence is much less trouble.
Hero of Another Story: Lion King 1½ (Or 3: Hakuna Matata in other regions) in which the first movie is told through their eyes.
Made of Iron: They survive A LOT in the TV series. One of the best examples would be how much poor Pumbaa goes through in the short span of the "Stand By Me" scene.
Malaproper: Pumbaa, occasionally, for example saying "I gravel at your feet" instead of "grovel" and messing up Timon's saying "You've gotta put your past behind you" as "You gotta put your behind in your past". Timon corrects him both times.
Man Child: Boy, are they! Especially since they tell Simba to let go of his responsibility.
Anti-Villain: Arguably, Type IIs. Yeah, they wanna help Scar overthrow Mufasa's reign, but it's mostly because they're starving and are looking for a way to improve their lives... It doesn't work out very well for them, but still, they tried.
Ax-Crazy: While Shenzi and Banzai are prone to breaking out into hysterical laughter, they're otherwise quite stable. Ed, on the other hand, clearly has some worrying problem.
Better Living Through Evil: They pretty much only followed Scar because he promised they would "never go hungry again"... And when it turned out he couldn't uphold his end of their bargain and give them their meal tickets, it became increasingly clear that they were starting to get fed up with their new king.
Big Bad: Arguably of Lion King 1/2. Sadly, they only appear in 2 scenes in that film.
BreakoutCharacters: They have a cult following and are immensely popular in fanart, particularly Shenzi.
Butt Monkey: Banzai, who gets claw-marks and thorns in his butt.
Cloudcuckoolander: Ed... We don't really know what he's saying but he's clearly not all there and seems to have most fun out of the Hyenas.
Comic Trio: They offer a lot of humor in the movie.
Equal-Opportunity Evil: For all the Nazi imagery during Be Prepared, the Hyenas only ever speak ill of lions, and even then this seems to be more about them feeling like the lions oppress them. Also, their boss is a lion. It goes two ways, too: Scar might look down upon the Hyenas, as he does with everyone, but he's the only lion who interacts with them on friendly terms.
Not So Harmless Villains: They can be pretty ruthless when they start hunting or going by Scar's orders, As Scar found out the hard way when he tries to put the blame on them, although they are also quite goofy.
Odd Name Out: Ed is the only one of the trio who does not have a Swahili name. In fact, he's one of the few characters in the whole movie without one.
Psychopathic Manchild: While they are not as immature as Timon and Pumbaa, their behavior (although less so with Shenzi) can get childish at times, such as the infamous "No King! No King! La! La! La! La!", bit. Typically, they come off as mischievous teens, particularly in the series.
The Starscream: Shenzi is actually this to Scar, especially after he took over the Pridelands and kept everything to himself, causing the hyena and her fellow comrades Banzai and Ed to become embittered of him and start spending time trying to overthrow Scar. When Scar loses in a fight against Simba at the end of the film, the hyenas finally confront him for the very last time and succeed in their plot of killing Scar.
Terrible Trio: Shenzi, the female, is the leader and the smart one, Banzai appears to think entirely with his muscles, and Ed is either insane, mentally handicapped, or faking it (the latter Jim Cummings seems to have confirmed).
Too Dumb to Live: Averted. Usually the bad things that happen to them are bad luck or timing.
What Happened to the Mouse?: In the sequel, they only get a passing mention that they and the rest of the hyenas left the elephant graveyard shortly after the events of the first movie, and after the battle they don't appear in the third at all. They did appear from time to time in Timon and Pumbaa.
Would Hurt a Child: Aware of who Simba is, they corner the young cub and Nala after the two young lions wander onto the elephant graveyards. Mufasa shows up to run off the hyenas.
Daddy's Girl: Lampshaded by Kovu. However this is later deconstructed when Kiara is an adult and her father still can't see her as an adult or listen to her. Reconstructed at the end, when the Pridelanders and Outsiders become one.
Rage Against the Reflection: During "Not One Of Us", as he's being driven from the Pride Lands, he looks at his reflection in the river. While Simba once saw Mufasa in a pool of water, all Kovu sees is Scar, which leads to this.
Ax-Crazy: Look at her Villain Song and her actions in the final battle. Zira is downright psychotic!
Big Bad: Of the sequel who wants to get rid of Simba and the other Pridelanders.
The Chessmaster: Despite being Ax-Crazy, she shows some apsects of this. She trained Kovu from his adoption to sneak into the Pride Lands and become her instrument of Simba's destruction. Then she proceeds to use this to throw Simba off his game by revealing it to him (even though Kovu already underwent a Heel-Face Turn by the time).
The Dark Side Will Make You Forget: Its implied by how she reacts to Nuka's death that she did genuinely love her kids (and Scar, considering he's the one the revenge plot is for), but is so consumed by her thirst for revenge she's lost sight of that.
Disney Villain Death: Worth mentioning is her death was originally much darker, including her being Driven to Suicide and letting go of her own free will. It even would've shown her being crushed by logs in the torrent.
Dragon Ascendant: Is Scar's mate, thus was most likely his second-in-command. She didn't appear in the first film at all, but becomes the Big Bad of the second one.
Fatal Flaw: Her thirst for vengeance. While she shows at Nuka's death and other times that she loves her children, her all-consuming thirst for vengeance causes her to be an Abusive Parent, ultimately causing the death of one of her children and the Heel-Face Turn of the other two, as well as her own demise.
The Sociopath: While Scar, being more calculating and subtle, would qualify more as a psychopath, her harsh attitude and aggressiveness make her this. Her Villain Song is not subtle about her being this.
Villainous Breakdown: Naturally, she was never the most sane person, but after Nuka dies, she throws her Evil Plan out the window, banishes her adopted son, and starts a full-out war with the Pride Lands. Gets even worse when Kovu and Kiara return and stop the fighting, threatening her own daughter with death.
"I could be a leader if (Zira would) just give me a chance!"
