'''Basic Trope''': A dangerous character prone to random violence.

* '''Straight''': Alice is obviously nuts and runs towards Bob swinging a large shard of glass.
* '''Exaggerated''':
** Alice spends all day doing nothing but [[PsychoKnifeNut sharpening her knives]] and [[IronicNurseryTune singing sinister versions of nursery rhymes]].
** Alice [[GunNut always carries some kind of firearms]] [[PsychoKnifeNut or edged weapons with her]], [[HairTriggerTemper goes into a frenzy after hearing any comment in her address, even if it is good]], [[BloodyHilarious collects human limbs and blood]], [[{{Sadist}} enjoys the]] [[LovesTheSoundOfScreaming screams and cries]] [[ToThePain of frightened and suffering people]], is [[LackOfEmpathy completely devoid of empathy]] [[AboveGoodAndEvil and conscience]], and has fun in {{gorn}}s, [[SadistShow Sadistic Shows]], [[{{Pyromaniac}} arson]], murders, [[TerroristWithoutACause terrorist acts and other atrocities]]. "The bigger and more blood, the better," she says.
** OmnicidalManiac
** InsaneEqualsViolent
* '''Downplayed''':
** Alice is mentally unstable, however, she isn't particularly dangerous.
** HotBlooded
** Alice is a dangerous person prone to violence towards others and DisproportionateRetribution, but she's calculating and decisive, rather than impulsive and thoughtless.
** Alice is not exactly violent but is prone to say death threats in NoIndoorVoice.
* '''Justified''':
** Alice was intentionally shaped into a homicidal maniac by the cult that raised her.
** Alice is diagnosed with a serious mental illness InUniverse (such as Paranoid Schizophrenia).
** Alice becomes violent because she can't control her anger (aka. Intermittent Explosive Disorder).
** Alice has irrational mood swings and anger that cause her to act out in violence (aka. Borderline Personality Disorder).
** Alice suffers from SplitPersonality where one of her personalities or alter egos is crazy, unstable and insane.
** Alice is completely insane and doesn't have restraints.
** Alice [[HearingVoices hears voices that tell her to kill things]].
** Alice is [[DemonicPossession possessed by a demon]].
** Alice loses control to a SuperpoweredEvilSide.
** Alice becomes insane over love because LoveMakesYouCrazy.
** Alice was injected with a PsychoSerum.
** Alice gains superhuman powers and abilities and becomes DrunkWithPower.
** Alice is BrainwashedAndCrazy.
** Alice is [[TheParanoiac a paranoiac]], and thinks that everyone's out to get her, so she violently lashes out at them.
* '''Inverted''':
** Alice's insanity makes her [[ExtremeDoormat meek and ineffectual to an unhealthy degree]].
** Alice is a SuicidalPacifist, unwilling to take up arms even when confronted by her most ruthless enemy and choosing to FaceDeathWithDignity instead.
** [[TheOphelia Adorably crazy]] Alice is imprisoned in a BedlamHouse, where she is [[PlayingWithSyringes tortured]] by a MadDoctor.
** Alice is the [[OnlySaneMan most sane]] and peaceful person, who is surrounded psychotic and sadistic people.
** [[TheStoic Icily logical Alice]] is a ProfessionalKiller who always does her murders with cold rationality and detachment, thinking only about completing her mission.
* '''Subverted''': The insane Alice runs towards Bob swinging a large shard of glass; Bob prepares for the worst when suddenly Alice holds the shard out and asks Bob to please clean [[CompanionCube Mr]]. [[ICallItVera Shimmers]] for her.
** Alice was faking it so she can expose [[DevilInPlainSight her boyfriend]], who is AxCrazy for real.
* '''Double Subverted''': ...and as soon as Bob is distracted, Alice takes out some piano wire and proceeds to [[CruelAndUnusualDeath murder him horribly]].
* '''Parodied''': Somebody calls Alice "Ms. Poopypants". She proceeds to grab an axe and kill everyone within a five-mile radius in an [[BloodyHilarious extremely over-the-top manner]], screaming [[Film/TheShining "Heeeeeeeeere's Alice!"]]
* '''Zig Zagged''': Alice frequently needs to take meds to keep herself stable. Thanks to RuleOfFunny and/or NegativeContinuity, what exactly the pills do varies wildly from episode to episode; in episode 3 she was merely [[AttentionDeficitOohShiny annoying without them]], but in episode 56 she forgot to take them and [[InsaneEqualsViolent subsequently attempted to murder Bob]].
* '''Averted''':
** Alice's insanity does not have any significant impact on how violent she is...
** ...or Alice is not insane at all, just an old good BloodKnight.
** Alice is fully aware of what horrid actions she's doing ([[MyGodWhatHaveIDone regret]] [[IRegretNothing optional]]).
** ProfessionalKiller
* '''Enforced''': Alice's ax-craziness, combined with her [[MsFanservice good looks]], is meant to appeal to a [[DracoInLeatherPants certain viewer demographic]].
* '''Lampshaded''': "Woah, Alice, you're looking pretty creepy holding that shard of glass. You're not going to murder me in a bloody and incredibly painful manner, are you?" Cue GoryDiscretionShot.
* '''Invoked''': The [[MoralEventHorizon irredeemably]] [[CompleteMonster assholish]] BigBad that Alice owes her life to attempts to drive her insane in order to make her a more efficient killer for TheEmpire (TheMafia, TheSyndicate, MurderInc, [[NebulousEvilOrganization whatever]]).
* '''Defied''': "Alice, I think it's time for you to talk to a psychiatrist."
* '''Exploited''': Alice acts insane, but is in fact perfectly normal and just [[{{Troll}} likes to freak people out]].
* '''Discussed''': "What about Alice?" "I don't trust that Alice. [[FauxAffablyEvil Sure, she acts nice and all, but it just seems like a cover for a ticking time bomb]]..."
* '''Conversed''': "In a horror story, right now would probably be the part where Alice has a [[FreakOut mental breakdown]] and murders, everyone, graphically." "Yeah, good thing we're [[TemptingFate not]] [[LeaningOnTheFourthWall fictional]] [[NothingExcitingEverHappensHere characters]], [[ThisISReality right]]?"
* '''Deconstructed''':
** Alice suffers from a genetic disorder that causes frequent hallucinations, bringing back memories of [[DarkAndTroubledPast her traumatic, abusive childhood]]; she reacts violently, striking down anyone in her path and believing it all to be in self-defense.
** Her sociopathic elements do ''not'' stem from genetic issues or a FreudianExcuse; [[UtopiaJustifiesTheMeans it stems from her raw determination to do whatever it takes to achieve a goal]]. However, others fear the fact that this person is really not any different from themselves; thus, they call her "insane" as a way to make it more "acceptable" to kill her.
** Under the mentality that InsaneEqualsViolent, the public ostracizes ''anyone'' with a psychological disorder as they believe "psychological disorder" automatically means "insane serial killer in waiting." This deprives the individual of crucial social support that would help them recover from or cope with the disorder.
** Alice tries to join the villains after getting ostracized for her actions. However, she could barely contain herself from killing anyone who provoked her. Unfortunately, the villains [[EvenEvilHasStandards didn't like this]] and [[PragmaticVillainy abandoned her for causing so many problems.]]
* '''Reconstructed''':
** Alice realizes her problem and [[ItsNotYouItsMe isolates herself from society]], unwilling to face the consequences should she [[UnstoppableRage go berserk in the middle of a crowd]].
** Alice is known in-universe unique case in the psychiatric community and is only made more terrifying by the fact that no one understands what drives her insane rampages or how they're triggered.
* '''Played For Laughs''': OnceAnEpisode, Alice escapes from the asylum and attempts to murder Bob in increasingly flashy and ridiculous ways. Due to some trick of fate, Bob somehow manages to [[TheFool escape unscathed and none the wiser every time]], and Alice is promptly captured and thrown back in the loony bin.
* '''Played For Drama''': To protect the people that she loves, [[ReluctantPsycho Alice]] [[FightingFromTheInside attempts to control her homicidal impulses]], but her will grows weaker with each passing day...
