"You don't care about anything except you. You just want to persuade people that you love 'em so much that they ought to love you back. Only you want love on your own terms. Something to be played your way, according to your rules."
Lelouch of Code Geass has been frequently compared to the below-mentioned Light Yagami, and though he doesn't move into full A God Am I territory, he comes pretty close. He repeatedly states his intention to "destroy the world and make it anew" and that he is "the man who performs miracles". However, he might be a deconstruction of this trope because his main motivation for everything he does is his little sister Nunnally and actually making the world a better place rather than himself, and for all his extreme arrogance, he is very self-sacrificing whenever she is involved in a situation, extends some of this protectiveness to a small number of close friends, and can be incredibly self-critical when things go south,.
Cell also has shades of this, especially after he reaches his Perfect Form.
Pride in Fullmetal Alchemist. He's utterly obsessed with himself to the exclusion of all others. Justified as he literally is arrogance given human form, and as such, has no emotions beyond self-love and satisfaction.
Naru from Ghost Hunt. He has a name besides Naru (which is a nickname), but nobody else in the cast uses it.
Al Da Flaga of Gundam SEED is a narcissistic parent, who raised his son (Mu La Flaga) with the intent of making him nothing more than an extension of his own ego. When Mu insisted on being his own person, Al locked him away in a Big Fancy House and had himself cloned. He then raised the clone to believe that it had no identity of its own, and existed only so that Al's legacy could live on, effectively trying to turn the clone child into a perfect duplicate of himself. He succeeded instead in creating a Woobie, Destroyer of Worlds and Misanthrope Supreme who sought the annihilation of the entire human race and had to wear a mask in order to give himself a sense of identity.
Asuka Langley Sohryu from Neon Genesis Evangelion seems to fit the bill perfectly with her boisterous and egocentric attitude but that's just a cover for the fact that she has a very LOW opinion of herself and thus an obsessive need to be adored and accepted. However this is not a subversion—that particular defense mechanism is probably the most widely accepted explanations for narcissism.
"What a crime... such a breathtaking crime. That God would create a star as bright as I. And I know it's a disgrace, to admire this perfect face, reflected in your eyes."
Jessie and James of Pokémon live for style, which only makes them that much more lovable. Jessie's Berserk Button is any injury done to her hair or her beautiful face; James carries around photos of himself to look at in his spare time. They dress up (stylishly) for no particular reason, silhouette themselves against the light, wave roses around and in general steal every scene they walk into. When they're about to die their priorities are clear:
Jessie: I'll always remember what a wonderful dresser you were. James: So will I!
In Sangatsu No Lion, Shimada accuses Gotou of being one, due to having a well-built physique that one would not normally expect from a professional shogi player.
Seto Kaiba from Yu-Gi-Oh! is incredibly proud and self-involved. In the anime he is slightly nicer and a protective big brother to Mokuba.
Paptimus Scirocco of Zeta Gundam is a Dark Messiah who manipulates and discards his followers like pawns on a chessboard. While he does care about them on some level, Scirocco largely views his minions in terms of what they can do for or to him, and uses constant emotional manipulation to keep them in line (especially the women). Even his Utopia Justifies the Means rhetoric contains an undercurrent of "only I can save the world." He has a typically narcissistic appreciation for those most like himself to boot—it's worth noting that the only woman (indeed the only person) he has any respect for is fellow Magnificent Bastard Haman Khan, and that the measuring stick he uses for her greatness is his own inability to manipulate her.
Lex Luthor hate Superman for holding humanity back...from worshipping him instead. While he's not incapable of empathy, he has trouble viewing his employees and allies as anything other than extensions of himself, and is a major Control Freak who cannot stand it when those around him have different opinions from him.
In the Silver Age Luthor's hatred for Superman began when the latter as Superboy saved his life from a chemical fire after Luthor's experiment to create life went awry. Luthor not only blamed him for intentionally sabotaging his experiment, he also blamed him for turning bald as well. Now if that's not vanity, I don't know what is.
Holmes accuses Professor Moriarty of "acute narcissism" in Sherlock Holmes: A Game of Shadows. Considering that Moriarty can't seem to prevent himself from smiling every time Holmes mentions his intelligence, and takes a moment to gaze into a mirror and smooth his clothes before engaging in Cold-Blooded Torture, it seems Holmes is right as usual.
Rita: Not to give you a big head, but I kinda missed you.
Loveless: Well isn't that a coincidence. I kinda missed me too!
The mentioned-but-never-seen Professor of Applied Anthropics of the Unseen University has put forth the Very Strong Anthropic Principle, which holds that the entire point of the universe is to give rise to the Unseen University so that it may house a Professor of Applied Anthropics (Footnotes comment that virtually everyone secretly believes this, with minor variations of a fill-in-name-here nature). Later in the book in which this is mentioned, one of the wizards mentions the principle, and comments that it's jolly decent of the Professor to share the universe with everyone else.
Gilderoy Lockhart, from Harry Potter. He's so ridiculously stuck-up, it's Played for Laughs. But then he gets what he deserves when Harry and Ron pwn him and force him to accompany them to the Chamber of Secrets. Then, he accidentally loses his memory, which conveniently erases all his smug self-importance and turns him into a cheerful Man Child. His actor, Ken Branagh, has specifically rejected the idea that Lockhart's secretly insecure - the narcissism is 100% genuine.
Also clearly the inspiration behind Narcissa Malfoy. But then, she is subject to majorCharacter Development when it is shown that all she really wants is to be with her family, to the point that she spares Harry out of gratitude for reassuring her that her son is alive.
They're all overshadowed by Voldemort in this department!
In Death: A number of characters in the series can be put in this category. Then again, they tend to be sociopathicserial killers. Clearly, characters in those categories probably would love no one but themselves.
In Malignant Self-Love: Narcissism Revisited, Sam Vaknin studies the mindscape of malignant narcissists from the psychodynamic point of view.
Dorian Gray from The Picture of Dorian Gray by Oscar Wilde is modeled after the Greek character of Narcissus and even painted dressed as him at one point.
Redwall's Emperor Ublaz Mad Eyes is self-obsessed to the point that he thinks it's perfectly reasonable to put all his manpower (or beastpower) into attacking a small and unimportant tribe several thousand miles away so he can have their family heirloom of six pink pearls. Just because he thinks they'd make a pretty crown for him, not because they're magical or anything.note (As it turns out, they may be, but not in a useful way.)
Jaime and his twin sister Cersei from A Song of Ice and Fire are both this, and it is implied that this is the underlying cause of their relationship because they look so much alike, particularely when they were younger. Jaime to a far lesser degree - he seems to feel some genuine romantic attraction to his sister, and is able to admit some of his mistakes.
Angel is viewed as narcissistic in the show and his spin-off show turns that into a Running Gag. On the DVD Commentary for "Billy", the writers admit they enjoy writing scenes showcasing Angel's "narcissism". The Running Gag in series 2 builds to the finale arc where he finds himself in an alternate dimension. While the gang discusses their plight, Angel can be seen in the background utterly distracted by his reflection. Once the gang has recovered from the shock of seeing him being able to reflect at all, Lorne has to forcibly drag him away from the mirror.
Lorne: "Come on, Gorgeous, you can stare at yourself in my grandmother's glass eye."
Angelus possesses all of Angel's narcissistic inclinations with none of the compassion to off-set it. He cannot shut up and is one of the cockiest, most dangerous and sociopathic characters in the entire show.
In a warped way, Spike loves Drusilla and Buffy. However, it doesn't stop him from causing pain for everyone around him. A particularly egregious example of Spike hurting Buffy causes Spike to feel guilty enough to go through trials to regain his soul, so he will not be so hurtful again. However, he still retains his edge and in the Angel spin-off, Angel's Running Gag is expanded to include him as well, culminating in them competing for everything from their place in world-shaking prophecies to trying to "save" Buffy from her latest boyfriend simply because they feel inadequate against his prowess among women.
Glory is one to an utterly ludicrous degree. She even forces her minions to constantly come up with new ways of praising her.
The First Evil: "You think you can fight me? I'm not a demon, little girl. I am something that you can't even conceive. The First Evil. Beyond sin, beyond death. I am the thing the darkness fears. You'll never see me, but I am everywhere. Every being, every thought, every drop of hateï¿½" Doesn't look like modesty is this thing's strength.
The Master from Doctor Who is completely obsessed with his own brilliance and considers the Doctor his only equal; few of his evil plots have a clear long-term goal besides getting his arch-enemy's attention. He takes it to the absolute extreme in "The End of Time" when he converts the entire population of Earth into duplicates of himself...all of whom are as pleased with this as the original.
John Simm: (on the commentary) I knew he had a high opinion of himself before, but I had no idea he's that narcissistic.
The Doctor himself is also one. He just happens to be the good guy.
The title character of House has shown narcissistic tendencies, which has not escaped the notice of any of the main cast.
It's Always Sunny in Philadelphia is a case where the whole main cast is narcissistic to a degree, but special mention has to go to Dennis, a man so pathologically vain that an offhand remark about his weight is enough for him to starve himself until he passes out. He thinks he irresistable to women, but his reliance on his makeup and girdle tends to send the wrong message.
Cat from Red Dwarf is absolutely in love with himself. The most telling example is when a Shapeshifting Seducer assumes the form that he desires most... himself.
Cat: So I'm the object of my own desires?
Shapeshifter!Cat: Is there anyone more deserving?
Dr. Cox from Scrubs is the greatest doctor of them all, a diagnosing machine, this fabulous thing. Too bad his personal life is in shambles. The show has also delivered An Aesop when showing how a little bit of confidence is not necessarily a bad thing and goes a long way towards making their patients feeling at ease.
Lex and Lionel Luthor from Smallville. Lionel's an Archnemesis Dad and Corrupt Corporate Executive who has trouble seeing his company and his son as anything more than extensions of himself, and is willing to break almost every law imaginable in order to stay on top. Possession by Jor-El eventually rids him of the worst of these traits, though he remains manipulative and grandiose long after his Heel-Face Turn. Lex starts out as a "Well Done, Son" Guy who tends to bring up his own problems in almost every conversation he has. This problem only gets worse as time goes by, and his delusions of heroism and need for adulation become more and more extreme; by the end of the show he's moved well past narcissism and into fullblown psychopathy as his need for control and someone to blame take over his life.
Kings: King Silas Benjamin is a blatant narcissist, who cannot separate the good of his kingdom from the good of Silas. He views his children and his nation as extensions of himself, and takes honours going to anyone else as a personal insult. His wife and son also display traits of this.
Alice Morgan from Luther is profiled by Luther as a malignant narcissist, a nasty subset of narcissism that includes sadistic and antisocial elements.
The POV character in Dead or Alive's "Far Too Hard," who comments that he is "fascinated with the profile in [his] mirror" and ruefully notes that you should "never, ever make it with your own reflection."
When he first debuted in the WWF in 1993, Lex Luger was billed as "The Narcissist". He often posed in front of a 3-way mirror set up in the ring before matches.
In the mid-2000's, Mark Jindrak played a similar character, billed as "The Reflection Of Perfection".
Cody Rhodes was like this during his "dashing" persona from 2010-2011 and had a digital mirror during his entrance.
Religion and Mythology
The Trope Namer Narcissus, was a boyish (aka Bishōnen) Greek Hunter who was punished by the gods to fall in love with his own reflection. Why that is depends on which version of the story you hear, the most famous being Ovid's version where he rejected Echo and didn't realize the reflection was his own. Another has Narcissus falling in love with his twin sister, and after her death, pretending his reflection is her. What happens after also varies, from a slow death due to starvation and thirst because he would not look away to drowning in an attempt to kiss his reflection, to stabbing himself when he realizes that his reflection is just a reflection and will never love him back. Regardless of cause of death, or a sympathetic god transforming Narcissus so he could stare at his reflection forever, regardless a flower either grew in the place where he died or he was transformed into one: the Narcissus plant, more commonly known as the daffodil.
Satan in the versions where he becomes jealous of God and rebels against him.
Orsino in Twelfth Night, though he might snap out of it by the end.
Warhammer has Sigvald the Magnificent - the favoured champion of the Chaos God Slaanesh, Lord of Vice and Excess. Sigvald is so narcissistic that he has his shield polished to a mirror sheen so he can look at himself in battle, and is often distracted by his own reflection even in the heat of combat. His narcissism even causes him to launch his followers on wars of aggression to punish people whose hair is said to be more beautiful than his (the high elves if you must know), or the makers of wines he finds dull and tasteless. Many champions of Slaanesh show similar behaviour.
Beholders in Dungeons & Dragons take this to an extreme. Each considers itself to be the pinnacle of creation and the perfect reflection of the Great Mother, the deity that created them. Anything that isn't a beholder is barely worth noticing. Beholders of other breeds are hated foes that must be slain on sight. Beholders of the same breed are tolerated inferiors, except technically each Beholder is its own breed. Beholders are also very good at noticing even the slightest difference in another beholder. A beholder with slightly bumpier skin or a slightly sharper teeth is as much a hated rival as a beholder with more obvious differences. Every beholder's belief that it is a perfect reflection of the Great Mother is justified because the Great Mother is a shapeshifter who adopts a form that matches that of the beholder looking at her thus reinforcing the beholder's narcissism. If all this seems crazy, that's because it is. The Great Mother is completely insane by human and even beholder standards.
Vyers of Disgaea both thinks and speaks very highly of himself, but he is actually a very nice guy.
Fawful from Mario & Luigi. Any game. He speaks of himself in third person in a positive way, puts his own image on everything and everyone in the world and seems to want everyone to view him like he does himself. Generally, he's an extreme narcissistic with Mind Control technology gone insane with power.
Everyone in the series qualifies, more or less. One of the Mario Party games had its Excuse Plot be that every character wanted a land they found to be named after themselves!
Florent L'Belle from Phoenix Wright: Ace Attorney - Dual Destinies would be like putting Vega on the stand. Always overflowing with self-praise for his own appearance, he even has his own line of beauty products that he publicizes but refuses to actually market (weird as that sounds). Fitting, as both are Capcom creations.
Inverted with Karkat (aka carcinoGeneticist) of Homestuck. Troll romance is complex and includes kismesissitude, which is a sort of attraction based on hatred and personal rivalry. Karkat's closest thing to a kismesis is himself due to unshakable belief in whatever his current mindset is a searing hatred of his past and future behavior. The other trolls find this hilarious.
Karkat actually seems rather chagrined when he realizes this fact; possibly because kismesissitude is actually related to breeding and it may not be possible to provide the proper genetic material when you're your own kismesis (and being unable to provide genetic material from either of the breeding relationships is grounds for execution in Karkat's culture).
Ménage à 3 features international lingerie model Senna, who is deeply aware of her own international model-grade looks, thinks that nothing short of black magic can divert someone's interest away from her, and assumes that when her boyfriend is nice to one of her rivals, he must be working on some complex plot on her behalf.
Knock Out from Transformers Prime is even more narcissistic. True, he has displayed Ho Yay with Breakdown, but Word of God has stated that it doesn't really matter whether he is attracted to males, females or both because he is first and foremost in love with himself.
Ratcliffe from Pocahontas loves himself almost as much as he loves gold.
The Evil Queen of Snow White, who had a magic mirror specifically to tell her that she's the most beautiful in the land.
Scar of The Lion King is this trope turned Up to Eleven. "Meticulous planning, tenacity spanning decades of denial is simply why I'll be king undisputed, respected, saluted and seen for the wonder I am, yes my teeth and ambitions are bared, be prepared!" The song is called "Be Prepared" and can be listened to here on Youtube.
The Italian version of the last part translates as: "I'll be a king admired, feared and loved, nobody is better than me!"
And in the French version we have "Le seul dieu vivant qu'on acclaime!", which means "The only living god to be acclaimed!".
Frollo of Hunchback Of Notre Dame is a textbook narcissist who projects his own lust on Esmeralda, as well as being a Knight Templar. "Beata Maria, you know I am a righteous man, Of my virtue I am justly proud / Beata Maria, you know I'm so much purer than the common vulgar weak licentious crowd..."
