!!'''Norman Bates'''
[[quoteright:243:http://static.tvtropes.org/pmwiki/pub/images/NormanBates_Psycho_6557.png]]

->'''Played By''': Anthony Perkins (the whole film series), Henry Thomas (Young Norman in ''Psycho IV'')

* {{Adorkable}}: An awkward, shy momma's boy... At first.
* AffablyEvil: When running a motel, one needs to be a people person.
* AntiVillain: As he notes during his conversation with Marion Crane on private traps, "I was born into mine. I don't mind it anymore".
%%* AxCrazy
* BadLiar: [[spoiler: Although surprisingly enough, his stuttering and incessant chewing goes some way in convincing Arbogast that he had nothing to do with Marion's disappearance.]]
%%* BeingEvilSucks
%%* BewareTheNiceOnes
* CartwrightCurse: [[spoiler: Connie (from ''Psycho IV'') is the only one of Norman's love interests who escapes a tragic fate.]]
* CreepyCrossdresser: When his mother personality takes over.
%%* CuteAndPsycho
* ADateWithRosiePalms: Subtly implied in the original, and flat out shown in the remake.
* DarkAndTroubledPast: Father died when he was five years old, leaving him in the care of an overbearing and somewhat incestuously inclined mother, who would emotionally abuse and degrade him.
* DoomMagnet: [[spoiler: All of his love interests die as a result of getting too close to him.]]
* DrivenToMadness: By his domineering mother, no less.
* DrivenToVillainy: When his mother takes a lover and continues in bullying him.
* ExtremeDoormat: To his mother, who deliberately made him dependent upon her after his father's death.
* FreudianExcuse: The abuse he was subject to by his mother when he was young.
* GollumMadeMeDoIt: The last scene of the film is his mother personality plotting and scheming to blame Norman for the murders.
* HiddenDepths: Shown to be somewhat of a nihilistic philosopher during his brief interactions with Marion Crane.
%%* IJustWantToBeLoved
%%* InsaneEqualsViolent
%%* KnifeNut
* KubrickStare: Perhaps the most grim and soul destroying one in cinematic history.
%%* LonersAreFreaks
* MommasBoy: "A boy's best friend is his mother."
* MommyIssues: One of the most famous cinematic examples.
* MonsterSobStory: And one that works on both the audience and the characters he encounters during the course of the series.
* NiceGuy: When Mommy doesn't take over...
* OedipusComplex: Norman's mother deliberately isolated her five-year-old son from the outside world and made him utterly dependent on her after Mr Bates' death. Naturally enough, the twelve-year-old, completely co-dependent Norman then reacted rather badly to her remarriage.
* ThePeepingTom: In the parlor and hidden behind a painting, is a hole that looks into Cabin 1. He uses it to look at Marion Crane and Maureen Coyle.
%%* PsychopathicManchild
* ReluctantPsycho: In ''Psycho II'', ''Psycho III'' and ''Psycho IV''.
* SerialKiller: In ''Psycho II'', he is revealed to have killed 7 people before being captured at the end of the first film.
* SexIsEvilAndIAmHorny: When Norman finds himself attracted to women (such as Marion Crane), the "mother" side of his personality lashes out and seeks to rid him of his sinful urges by way of murder.
* SplitPersonality: Norman and his internalized mother.
* SplitPersonalityTakeover: At the end of the first film. In the words of the psychiatrist: "Norman Bates no longer exists". He gets better in the sequel, however.
* SweetTooth: Is always seen with a bag of candy.
%%* SympatheticMurderer
%%* TalkingToThemself
* TaxidermyIsCreepy: [[spoiler:That his mother is actually just a preserved and stuffed corpse is the great twist of the film.]]
* TheyLookJustLikeEveryoneElse
* TragicVillain: Although one with an ultimately happy ending, provided you see Psycho IV as being canon.

%%* BestServedCold: In ''Psycho II''.
* CruelAndUnusualDeath: [[spoiler: Impaled through the mouth with a kitchen knife in ''Psycho II''.]]
%%* GoneHorriblyRight
* HeroAntagonist: Towards Norman, in ''Psycho'' and ''Psycho II'', however, it's subverted in ''Psycho II'', as the Antagonist side of this trope outweigh the Hero part despite Lila still fulfilling the same trope.
* InspectorJavert: A non-cop version. Still hounds Norman and views him as the irredeemable murderer after he's been released from the mental institution in ''Psycho II''.
* NotSoDifferent:
** Seeing as how [[spoiler:Lila treats her daughter in ''Psycho II'', she has more than a few similarities to the mother that drove Norman Bates insane.]]
** And, of course, there's the fact that [[spoiler:she sets everything up to make Norman go insane again. Sure, she has a reason for not liking him because he killed her sister and several other people, but to attempt to send him back to the asylum and possibly kill again is just ''wrong''.]]
