Stanley Ipkiss / The Mask (Jim Carrey / Rob Paulsen)
- Acting Unnatural: Once he gets ahold of the Mask, it happens a lot.
- Adaptational Heroism: In the comic, Ipkiss gradually turns into a psychopath undr the influence of the Mask. In the movie, he is a much nicer guy, and his only "crimes" as the Mask are robbing a bank (okay, that is a legitimate crime), messing with the police and eliminating the Big Bad. In the Animated Series, he is still not above trolling authority and people as a whole, but Stanley otherwise tries to use the Mask's power as a force of good, with relative success.
- Adaptation Distillation: Though much of Ipkiss' personality is the same in the beginning of both the comics and the movie. In the comics Stanley becomes more psychotic and abusive whenever he doesn't have the mask on.
- Adorkable: Especially in the animated series.
- As Long as It Sounds Foreign: In the movies, The Mask has a Nordic/Viking origin. In the comics, it's African.
- Bad Liar: Somebody stole his pajamas!
- Becoming the Mask: literally.
- Beneath the Mask
- Berserk Button: In the animated series, The Mask has three big ones: do NOT mess with his face, his clothes, or the Coco Bongo. Because if you do, he will then indulge in his (second) favorite pastime: REVENGE!
- Butt Monkey: whether it's the comic, the movie or the animated series, Stanley tends to get treated like crap by almost everyone other than his closest friends, though he learns to stand up for himself as the film goes on. In the comic, that serves as his motive for revenge.
- And in the animated series, it's practically to the point that he reaches Woobie status.
- Chekhov's Gag: Stanley's favorite cartoons become the traits of the Mask (for starters, he spins like Taz).
- His head even morphs into the Tex Avery wolf from Red Hot Riding Hood.
- Cloudcuckoolander: The Mask personality.
- Comically Invincible Hero: Again, with the powers of the Mask.
- Cursed with Awesome: A few times throughout the animated series, this is how Stanley feels about having the mask.
- Curtains Match the Window: Stanley has brown hair and eyes.
- Deadpan Snarker: Both Stanley and The Mask have their moments.
- Extreme Doormat: Before he Took a Level in Badass in the film.
- An episode of the animated series called "Double Reverse" explored this and the claim that the mask unleashes Stanley's repressed wild side. When he starts acting more like the Mask as Stanley, he impresses his clients, gets a promotion and a hot girlfriend. Buuuut....since he's acting like the Mask when he's not the Mask, he can't change into the Mask anymore, which is bad news when an supervillain inevitably shows up.
- Fusion Dance: Kinda. There is no dance involved, but in the animated episode "Split Personality", the Mask is split in two. In an attempt to see if it works, Stanley puts the half on. It works to say the least, resulting in a literal fusion of the two. One half Stanley, one half the Mask.Stanley Half: So this is what I do as you...The Mask Half: It's the voodoo I do!
- Heroic Comedic Sociopath: Except in the comics, where he's a Villain Protagonist.
- Heroic Host: In one episode of the cartoon, a fairy who used to hang out with the Mask implies that it's wearers used to be much more violent and murderous, like in the comics, but Stanley turned the Mask into a much more heroic, though no less deranged, force.
- I Have This Friend: Stanley claims to be old college buddies with "The Mask".
- Large Ham: both as the Stanley and the Mask in the movie. In the animated series, Stanley is portrayed as a bit less hammy and more shy, but the Mask is still incredibly hammy.
- Only Sane Man: Stanley whenever he's NOT wearing the mask, especially in the animated series.
- Sexier Alter Ego: Note that he's not more physically attractive (unless you're into that sort of thing), but more confident and impulsive (and gets Reality Warper powers), and that's why he gets the Love Interest in the end.
- Slasher Smile
- Spared by the Adaptation: Died in The Mask issue 00, but is alive in the movie and animated series.
- Submissive Badass
- Troll: As the Mask, especially in the Animated Series.
- Weaksauce Weakness: Common cold in the Animated Series.
- With Great Power Comes Great Insanity: Whenever Stanley puts on the mask.
- Action Pet
- Canine Companion
- Frank Welker: His voice actor on the cartoon series.
- Evil-Detecting Dog: While not evil (at least in the right hands) Milo could tell from the start that there was something strange about the Mask.
- Non-Human Sidekick
- Team Pet: To an extent.
Tina Carlyle (Cameron Diaz)
- Chuck Cunningham Syndrome: When the movie was adapted into a Saturday morning cartoon, Tina was never seen and her existence was not acknowledged.
- Defrosting Ice Queen: Not cold, just a little aloof at first
- Distressed Damsel
- Expy: Of Kathy, Stanley's girlfriend, from the comics.
- Femme Fatale
- Ms. Fanservice
- Reformed Criminal
- Silk Hiding Steel
Charlie Schumaker (Richard Jeni / Mark L. Taylor)
- I Always Wanted to Say That: See below.
- Jerkass Façade: Comes across as really selfish at first, but he helps Stanley when he really needs him.
- The Lancer
- Only Friend: Charlie does appear to be Stanley's only friend.
- Took a Level in Badass: "Officers, arrest those men! ...I've always wanted to say that."
- Took a Level in Jerkass: His redeeming qualities disappear in the animated series.
- Who Needs Enemies?: He'll drop a conversation with Stanley to talk to a pretty girl.
- With Friends Like These...: He's not always good at being there for Stanley, see above.
Lieutenant Kellaway (Peter Riegert / Neil Ross)
- Butt Monkey / The Chew Toy: Especially in the Animated Series.
- The Comically Serious
- Hero Antagonist
- Inspector Javert: In the cartoon, he's got a grudge. In the comics though, it's justified.
- No Sense of Humor: See below.
- Moreso in the comics, where he's trying to hunt down and stop an artifact that turns anyone who wears it into an unstoppable, psychotic mass-murderer.
- Reasonable Authority Figure: In the comics.
- Shout-Out: In the cartoon, he wears a brown raincoat, much like another TV police lieutenant with no first name given.
- Straight Man: With almost no sense of humor.
- Took a Level in Jerkass: His dislike of the Mask is completely justified in the comic, and while he is misguided Hero Antagonist in the movie, he overall does nothing the could be considered unreasonable. In the Animated Series, on the other hand, he keeps treating the Mask like a criminal and chasing him, not matter how many times he saw him save the day or arrest actually dangerous criminals.
- Took a Level in Kindness: He however develops some respect for the Mask in following episodes of the animated series. He thanked the Mask for saving him from Putty Thing and accepted his proof that Stanley didn't counterfeit money in one episode.
Detective Doyle (Jim Doughan / Jim Cummings)
- Butt Monkey
- Captain Obvious
- Clueless Detective: Don't bother trying to give him a hint in Pig Latin.
- He's even more clueless in the cartoon, making one wonder how the hell could he have passed the police academy exams.
- Friendly Enemy: Tried to shake Stanley's hand after he saved the day.
- Plucky Comic Relief
- Took a Level in Dumbass: Both a film-wise and adaptation wise. In his initial scene at the bank, he seems to be quite intelligent and competent. By the time we see him at the park, he's suddenly a ditz and by the film's end he's a certified idiot (though some of that may have been him being influenced by the Mask's power). The cartoon made him even dumber.
- Angry Black Man: Lionel turned into one when Kellaway/Big Head started fighting the police, and challenged Big Head to a fist fight. Big Head almost killed him, and would have if Kellaway hadn't regained control of himself.
- Black Best Friend: Oh hell, Lionel is Kellaway's ONLY friend!
- Black Dude Dies First: Subverted, as Lionel is one of the few people Big Head doesn't end up killing.
- Idiot Ball: Lionel challenged Big Head to a fist fight. This went as well as one would expect...
- Token Minority: Lionel is the only member of the named main cast who's black.
- The Watson: He's not only Kellaway's partner, but one of the few people in the police force that Kellaway even trusts.
- White Dude, Black Dude: Subverted. With Kellaway and Lionel it's more "angry dude, calm dude"., respectively.
Mrs. Peenman (Nancy Fish / Tress MacNeille)
- Butt Monkey: And how! Especially in the animated series (though, given how much of a mean old lady she is, Peenman is more of an Asshole Victim).
- Grumpy Old Woman
- Hair-Trigger Temper
- Jerk Ass
Peggy Brandt (Amy Yasbeck / Heidi Shannon)
- Distress Ball: In the cartoon.
- Easily Forgiven: In the cartoon Stanley doesn't seem too mad about her selling him out in the movie.
- Face–Heel Turn: In the movie, she turns Stanley over to Tyrell for money.
- Going for the Big Scoop: In the cartoon.
- Hot Scoop
- Intrepid Reporter: In the cartoon.
- It's All About Me / Narcissist: When she puts on the mask in the animated series episode "Counterfeit Mask".Stanley: I thought you wanted to help me so you could report a great story!Mask!Peggy: I don't need to report the story, darling... I AM the story!
- Karma Houdini: In the movie, since the scene of Peggy getting shoved in the printing press by Dorian and coming out as a bloodied newspaper that has her death on the front page was cut. She and Stanley became friends in the cartoon, on the other hand. But he never got over her selling him out.
- Ms. Fanservice: In the cartoon.
- Secret Keeper: In the animated series. Out of Stanley's small circle of friends, she's the only one that knows he and The Mask are one and the same. (Well, other than Milo, anyway.)
- Spared by the Adaptation: Since her death was removed from the theatrical cut of the movie, she is featured as still alive in the animated series.
- Took a Level in Kindness: In the cartoon; she is still constantly trying to exploit the Mask to get a scoop, but she at least no longer acts antagonistic toward Stanley.
- What Happened to the Mouse?: She disappears after Dorian puts on the mask and was presumably allowed by Tyrell and his men to walk away unharmed. Originally, he would follow up by tossing her into a newspaper printing press.
Dorian Tyrell (Peter Greene)
- Berserk Button: DON'T COME ANYWHERE NEAR HIS GIRL!
Dorian: You know what happened to the last bitch that ran out on me? Do you?!
- And if you're the girl in question, don't try to walk out on him if you value your life. In an earlier draft of the script and the extended workprint version of the film, he all but outright states that he killed one of his previous girlfriends when she tried to leave him.
Dorian: Nobody else does, either. And nobody ever will.
- Big Bad: In the movie.
- Domestic Abuser: Don't see too much in the movie, but it seems pretty obvious anyway.
- Evil Makes You Ugly: While the Mask makes Stanley bald and cartoonish, Dorian instead gets a demonic Game Face that even retains the hair.
- Evil Sounds Deep: When he wears the Mask, it makes his voice significantly deeper. See below.
- Hair-Trigger Temper
- Killed Off for Real: He doesn't come back in the cartoon or the sequel
- Law of Disproportionate Response: Get pushed around by the "Big Boss"... Blow up his Casino and everyone in it.
- Power Makes Your Voice Deep: When he wears the Mask.
- Red Eyes, Take Warning: When he's wearing the Mask.
- The Starscream: To Niko.
- Unstoppable Rage: When he wears the Mask.
Niko (Orestes Matacena)
- Asshole Victim: He is killed by Dorian once he gets the mask
- Bad Boss: Uses Dorian's mouth for a golf tee in once scene
- Greater Scope Villain: Is the boss of Dorian
Dr. Pretorius (Tim Curry)
- Arch-Enemy / Big Bad: in the animated series.
- Cyborg: And it's implied he did this to himself intentionally, without actually needing it.
- Expy: He looks a lot like Eugene Rapaz, a drug dealer from the comics. Tone down the mohawk and replace the eye lenses with glasses...
- Hammer Space: The tiny circular base of his head has the mechanisms to drive six small legs, a computer interface jack, various tools, a neural interface and circuitry, and one would assume a complex life support system to keep him alive without a body (albeit such a system may be meant for short term use as he's almost always attached to his robotic body).
- Heel Realization: Averted. He rejects the accusation that he is evil and explains that he is first and foremost a man of science. When he wears the mask and finally sees his monstrous inner self, he non-chalantly notes that he may be evil after all.
- Knight of Cerebus: In his first episode, until Villain Decay kicked in.
- Losing Your Head: When it happens, it grows spider legs!
- Mad Scientist
- Power Makes Your Voice Deep: During the one time that he wears the mask.
- Shout-Out: He shares his name with the mad scientist from Bride of Frankenstein.
- Tim Curry: His voice actor on the cartoon.
- Villain Decay: In his first appearance, he was a serious and dangerous antagonist who came up with a relatively credible plan (by cartoon standards, that is) and almost killed Stanley at least twice. In later episodes, while he would still turn out to be a threat occasionally, his plans became much goofier, and he started becoming more of a Butt Monkey like other villains. Granted, with an opponent like the Mask, it was probably inevitable.
- Arch-Enemy: In the comics. He takes a backseat to Dr Pretorius in the cartoon, though he is still a fairly persistant and important villain of his own.
- Bad Ass: Both in the comics and the animated series, he is one of the few guys who can actually give the Mask/Big Head a run for his money.
- Bald of Evil: In the comic.
- The Brute: More so in the comics than the cartoon, where he was a mob hitman and enforcer.
- The Comically Serious: In the cartoon. No matter all the absurd hijinks the Mask throws at him, he still keeps a serious, stoic face.
- The Dragon: To Dr. Pretorius in the cartoon, to the mob in the comics.
- Evil Redhead: In the cartoon.
- Knight of Cerebus: Even in the cartoon, the only humor we get from him is about how ridiculously invulnerable he is and how he won't show any emotion even in the most absurd situations. Aside from that, he is usually is played as a real threat.
- Implacable Man
- Nigh Invulnerable: In the cartoon. In the comics he could be taken down with enough of a beating.
- President Evil: A comic (likely based on the cartoon) had him running for Mayor of Edge City.
- Self-Mutilation Demonstration: Just to be clear here- comic Walter can bleed, though it doesn't seem to really hurt him. Cartoon Walter is impervious to wounds. That said... in the comics he had a disgusting habit of cutting himself just to mess with people's heads.
- Too Spicy for Yog Sothoth: On one occasion he got his hands on the mask. For some reason it didn't do anything to him.
- The Voiceless
Dr. Arthur Neuman
- Ax-Crazy: When he wears the mask in the animated series. It is frightening.
- The Cameo: The only character from the first movie to appear in the sequel, which was probably for the best...
- Deadpan Snarker: Emphasis on the "Deadpan". He's played by Ben Stein, what did you expect?
- Psycho Psychologist: Again, when he wears the mask.Stanley: I take advice from that guy?! He's mad!
- Reverse Psychology: In the animated series episode "Double Reverse", he suggests that Stanley use this as a way to make Stanley's life better. This advice winds up working a little too well, because since Stanley's acting like the Mask when he's not the Mask, he can't change into the Mask anymore.
- The Shrink
