Grizzled Private Detective who slipped into alcoholism and developed a bitter grudge against Toons after his brother got murdered by one of them when they were investigating a case in Toontown. He is hired to take some dirty pictures about Jessica Rabbit's affair with Marvin Acme, but is pulled into the murder investigation (against his will) after Acme gets murdered and Jessica's husband, Roger is framed for it.
Acrofatic: Eddie during his climactic dance number.
Action Survivor: His modus operandi to come out of trouble. He's also a smarter version of this.
Adaptational Attractiveness: Inverted. Book!Eddie, as a parody of a pulp hero, is noted by several characters as being very attractive. Movie!Eddie, as a parody of a noir hero, is beaten down and schlubby.
The Alcoholic: At the beginning of the movie Eddie Valiant has been an alcoholic since his brother was murdered by a Toon, but he drops the habit by the end.
Police Lieutenant: Didn't you used to be Eddie Valiant? Or did you change your name to "Jack Daniels"?
Anti-Hero: A Pragmatic Hero. Cynical alcoholic with a racist streak and a tendency towards violence? Definitely Anti-Hero. But he does get better once he stops drinking and by end of the movie, he's a lot nicer.
Badass Normal: Probably the only one human in among toons with this charateristic. He even manages to kill Judge Doom himself, who is a toon stronger and taller than him, by spreading dip everywhere.
Badass Unintentional/Accidental Hero: Eddie's not very happy to take care of Roger Rabbit's case since he became a Toon-hater. However, he manages to prove Roger's innocence, save Toontown, and avenge the loss of his brother all at the same time.
Circus Brat: Implied. One of his old photos shows himself, his brother, and his father (dressed as a clown) in front of a circus sign, the frame reads "On the road with Dad". His improvised circus act distraction at the end of the movie also supports this.
Unmarked Spoilers belowThe Hanging Judge of LA and Toontown, who thinks that the only way to repress the madness of the Toons is to make them respect the law... or more accurately, fear it. If he has to execute a few on his way to get the message across, so be it. It's later revealed that he himself IS a toon in a rubber mask, and wants to destroy Toontown (and the Toons while he's on it) so he can build a freeway and new city in place of it, thus making himself filthy rich. Ironic while considering that he's a Toon himself or possibly more horrific because he is one. He also killed Marvin Acme, R K Maroon and Teddy Valiant.
All There in the Manual: According to The Resurrection of Doom (a sequel graphic novel published a year after the movie's release), his real name is Baron Von Rotten, and he was a Toon who frequently played cartoon villains until an accident on the set rendered him thinking he was truly villainous.
Ambiguously Human: Even though he's technically a Toon himself, we never see what's behind the rubber mask.
The graphic novel does reveal a glimpse◊ of his true Toon form.
The Chessmaster: Everything from Acme and Maroon's murder and Roger being framed for the former's murder to plotting to destroy Toontown, and even the murder of Eddie's brother]] is all a part of his plan.
The Heavy: His murder of Eddie's brother and the death of Acme, have made both Eddie and Roger's lives change significantly
Evil Plan: He has a plan to melt Toon Town with his dip cannon and put a freeway in. Presumably his "excuse" for doing this is to accept kickbacks from the presumably wealthy developers of the gas stations, motels, cheap restaurants and billboards that would build up alongside the freeway, but his real motivation seems to simply be For the Evulz.
Eye Pop: Once revealed as a Toon, his eyes briefly bulge in and out while his pupils shrink and expand in a disturbing way. Does a traditional one in his Oh Crap moment.
For the Evulz: His possible reason for dipping the poor toon shoe.
Humanoid Abomination: For one thing, for a Toon and especially dangerous one; he has perpetually changing red eyes, golden hands that turn into weapons and a high pitched shrill of a voice. And everything else is a mystery as it is all covered by his coat and rubber mask.
Karmic Death: He's killed by the same Dip he created and planned to use to kill off his entire race.]] Serves you right for killing that cute shoe.
Lack of Empathy: For starters, in his establishing scene, he boils alive a Toon shoe just for cuddling by his feet! In addition to his treatment of his weasels as well the utter lack of guilt when admitting to have killed Eddie's brother, in fact views it as a great achievement show how much empathy he has
His New Era Speech speech about destroying Toon-Town to make a freeway, the sheer enjoyment of its completion shows how little he regrets estroying his own kind.
No-Holds-Barred Beatdown: His "fight" with Eddie after his reveal as a Toon is the latter running out of how frightened he was, jumps from a distance to grab him, toss him to the floor while turning on the then de-activated Dip Machine that would kill Roger and Jessica and finally punch Eddie across the room with an 'anvil he had turned his hand into. He had planned to simply saw Eddie in half literally. However, he then decided to take this slowly which gave Eddie the chance to use the Dip against him.
Psychopathic Manchild: His goals are simplistic and idealistic, but the extremes he goes to achieve these ends makes him out to be this - especially as a Toon who delights in prolonging his killing of Eddie just to make him die in absolute terror.
Psychotic Smirk: He has this when he melts the poor toon shoe in the dip. The thing is doing intentionally to show how cruel and sadist he and his Weasels are.
He then does this near-consistantly once he reveals to be a Toon.
Red Eyes, Take Warning: His real eyes. Not only are they red, but they briefly turn into daggers, then bulge out and swirl.
The Reveal: Not only is he the real villain behind all the murders, he's the toon who killed Eddie's brother!
Slasher Smile: At first he only tends to normally smile evilly, then after revealing his true identity and his real psychopathic nature he finally sports an horrendous one probably thinking of the fun he'll have beating and then killing Eddie.
Toon: A rather dark and disturbing take on this idea. As Judge Doom, he's portrayed for most of the film as an extremely anti-Toon human judge with over the top villainy and ambitions. While one could call him eccentric, something seems to be very "wrong" as he has pearly white teeth, stiff movements, completely dark glasses and a black outfit that covers the entirety of his body what he seems to desperate to hide. Underneath all that, he has the usual cartoonish childishness, but channeled into psychopathy and sadism. He also has mastered the use of Toon Physics to make his body itself into a very versatile lethal weapon.
Uncanny Valley: Invoked. Christopher Lloyd was given very pale make-up, was never shown to blink on camera, and has very stiff movements to make the audience feel something is very wrong about Doom. Especially once he reveals his red eyes and unnaturally high pitched voice.
Jerkass Ball: Acme generally seems like a good man, but he's still a homewrecking Millionaire Playboy frequently "gettin' it on" with Roger's wife. In spite of this, Acme really does love and cares deeply for the welfare of all Toons and promised to leave Toontown to them.
Ears as Hair: Roger wrings the water out of his ears and Eddie grabs him by the ear.
Expressive Ears: The animators mention that they took inspiration from ballet dancers when drawing Roger's ears. When restrained, Roger can even point with them.
Feels No Pain: At first, such as being immune to fridges being dropped on him, hitting himself over and over again with plates and even when Eddie's wringing his neck, but this is in truth a ziggzagged trope, as he clearly is in pain from Judge Doom strangling him. This can be explained because this trope is run on Rule of Funny, but being held by his neck over Dip is pure Rule of Scary.
Even if it doesn't hurt, Roger complains to Eddie that he does not like having his ears pulled.
Flanderization: Roger, compared to his original book counterpart. While the Roger Rabbit of the original book had some notable eccentric traits, he was also somewhat shifty and definitely not the Nice Guy he pretended to be. The Roger of the movie is a lot wackier and more, well, cartoony, and is genuinely a Nice Guy.
Kavorka Man: Played with. Not only is he married to quite possibly the hottest toon made, but he seems to be the envy of most Toon females, even Betty Boop. Jessica explains later that it's because he makes her laugh. Sure, Roger ain't the handsomest dude around, but he's a genuinely Nice Guy, pretty funny, as well as an A-list superstar.
By Toon standards though, Jessica is considered the lucky one. The key attribute of Toon society is humor, making Funny Animals pretty much the equivalent of supermodels.
The Klutz: He has a tendency to get his head stuck in things.
Roger's voluptuous Toon-human wife, who has been made into a sex symbol - both in and out of the movie - and seeing what she looks like, it's pretty justified.
Aww, Look! They Really Do Love Each Other: They never fight when they are on screen together, but her actions prior to that suggest she would have affairs behind his back. Turns out all of her actions both moral and immoral were in the name of saving Roger and helping him and Eddie clear his name.
Hidden Depths: Especially if you've only seen the posters and/or her pictures. Despite her looks and behavior (and the fact that she's clearly out of Roger's league appearance-wise), she really loves her husband. Jessica is also clearly one of the most intelligent characters in the film.
Not Evil, Just Misunderstood: At first glance, she appears to be morally ambiguous and devious as one might expect from a Femme Fatale, but she's not like that in any way. She's a good girl who just also happens to be incredibly sultry and loves her husband more than anything.
"I'm not bad, I'm just drawn that way."
Not so Above It All: You might think because of her more in-control Femme Fatale personality and the fact that she's more of a "mature" toon that Jessica Rabbit isn't quite as looney as the others. The movie sets her up like that, and then wittily breaks down the assumption.
Jessica: [about Roger] I hit him on the head with a frying pan and put him in the trunk...so he wouldn't get hurt.
Despite being mean and ruthless at their core, they're not immune to silly, cartoonish antics every now and again.
When they break into Eddie's apartment looking for Roger, Smart-Ass rants at all the others for laughing. At the bar, Smart-Ass laughs right along with them.
Not-So-Harmless Villain: They act like the typical incompetent villain - sidekick. However it's clear they are sociopathic and evil just like their boss Judge Doom since they cooperate with him in his genocidal plan to wipe out Toontown and the toon race, which they are a part of.
The Voiceless: Smart Ass is the only one weasel with a decent amount of lines in the movie - Greasy and Psycho have only one/two of 'em. Stupid just says "Toon Town is behind the wall, boss" and nothing more and Wheezy's only actual line in the film is a barely noticeable "Let's go!" right after Eddie and Roger free Bennie the Cab.
Weapon of Choice: Smart Ass and Greasy both pack handguns and switchblades, Psycho carries a straight razor in his mouth, Stupid holds a baseball bat with nail protruding at it's tip, and Wheezy's shown at one point wielding a Tommy gun.
A foul-mouthed, super fast cartoon taxi cab that is friends with Roger. He apparently has a history of run-ins with the law thanks to his rather chaotic driving skills. Has the supernatural ability to appear whenever someone sticks out their thumb.
