Rasputin's death in Anastasia was another offender. His body parts melt into nasty green ooze and his cloak collapses to the ground. And then his skeleton emerges, screaming in agony while being shocked by green electricity. His final death comes as a relief. Oh and it isn't a Karmic Death, Anastasia knows just what she's doing when she destroys the reliquary that is keeping him alive.
There are two very creepy musical numbers: "B-Movie Show", where a roomful of old appliances sing about being broken down for parts, and "Worthless", in which anthropomorphic cars in a scrapyard sang about their hopeless fates as they were being loaded into the crusher. A crusher that will later menace a human character. One of the cars even commits suicide when it drives itself along the crusher's conveyor belt so that its end will come faster.
The Disney Death of Air Conditioner. The guy has what can only be described as an anger-induced 'aneurysm'... after sparking and screaming for a good minute.
The scene where a lonely flower falls in love with the titular toaster, is quickly rejected, and promptly dies of heartbreak.
Mr Whiskers, after being transformed into a homicidal feline/bat hybrid monster by Weird Girl's attempt to replicate Victor's experiment, gets impaled by a flaming beam within the New Holland windmill while fighting Sparky. They don't show the impact, but you do see the aftermath.
Not to mention Sparky himself, offscreen. Judging by all those seams and patches holding his body together, it's not hard to imagine what he looked like at the scene of the car accident.
The sea-monkeys die by eating popcorn and exploding into liquidy guts. And this movie got a PG rating.
Kung Fu Panda 2 is significantly darker than the first was. At first, the deaths are off-screen, but still pretty gruesome, like getting blown to bits by a giant cannon, and being ripped apart by wolves. However, the one that really takes the cake is the Wolf Boss. Shen throws a knife in his stomach. On screen. Given that up to that point all deaths happened off camera and the generally cartoonish and larger than life violence, it was very shocking to see such a graphic, cold blooded killing. Immediately after being hit by the knife, however, the Wolf Boss exits the movie, so a corpse is never seen, but heavily implied.
Then of course, there's the genocide of the pandas which, while relatively low-key, is still freaking genocide. The death of Po's mother stands out, as we last see her leaving baby Po in a radish basket, running off-screen with the wolves chasing her, and then nothing but Po's crying as the scene fades away.
The Land Before Time has the villain Sharptooth drowned by a boulder into a pond, and the Littlefoot's mother die from a bite to the spine- on screen (mostly shadows), but you can see the bite, see the wound, and Littlefoot and the viewer watch her die.
The Last Unicorn had several moments of horror that were sure to cause sleepless nights — Mommy Fortuna's freak show gruesome death at the claws of a harpy and a giant fanged bull made of fire that seemed to trample over herds of beautiful unicorns.
The Mouse and His Child is best known for the animated film faithfully based off Russel Hoban's strange, metaphoric novella. Both the book and movie are essentially  for kids. In the movie, a pack of nasty Rats have an army of enslaved abandoned wind-up toys. When one of them breaks down, Manny (Peter Ustinov), the Rats' leader, gives the toy a mock-sympathetic speech — and then, as the toy pleads for its life, he sends for another Rat to demolish the toy for spare parts!
Manny then goes on to smash the titular characters to pieces with a huge rock. They get better. A Muskrat the characters had befriended earlier puts them back together — but we get to watch as he does so. The incongruously cheerful song playing over the scene just makes it creepier.
This sequence of events is rather different in the original book. There, the Mouse and his Child got smashed to pieces when an hawk dropped them from a great height. The one who fixed them was Manny Rat! (His Heel-Face Turn is much less ambiguous here than in the film.) As for Muskrat, he was squished by the tree he had the mice chop down.
At the end of The Nightmare Before Christmas, Big Bad Oogie Boogie actually gets his burlap "skin" torn off his body by Jack Skellington, causing all but one of the insects that make up his body to fall into the lava (the one that didn't is instead squashed by Santa Claus).
Thrax from Osmosis Jones dies a horrible, melting death in a glass of alcohol (having previously bragged about killing three people, including a little girl!).
Agatha's death in ParaNorman. The thought of an innocent 11-year-old girl being sentenced to hanging is very unsettling. Not to mention how it's suggested that the zombies chasing Norman the whole film were killed by Aggie's "witch powers" after sentencing her to death.
Drake, the main villain of The Pebble and the Penguin (also by Don Bluth) was dispatched with a boulder on the head. The boulder crushes him completely. In fact, the underside of the boulder can be seen when it rolls off a nearby ledge. There is nothing on it. Seriously, just imagine this scene being redone, but with blood!
Subverted in Rio where Nigel appears to have been shredded alive by the airplane's propellers at the end, but it's later revealed that he survived only to have lost all of his feathers in the process.
At the end of Robots, Madame Gasket is shredded alive inside her Chop Shop grinder.
The Secret of NIMH. Along with all the implied animal deaths at the N.I.M.H. laboratory, The Great Owl rather graphically dispatches a Giant Spider. The deaths in the final act were little better, particularly that of Nicodemus.
Shockwave was supposed to be stomped by Unicron, but they cut out the shot.
Red Alert was also supposed to die by being shot in the back by Devastator, but that scene was never animated.
Did everyone forget the first 5 minutes of this movie? An entire planet of robot people, BILLIONS of "men" "women" and "children" are sucked into Unicron's hungry maw, chewn up, and used as fuel! Genocide in my children's film? More likely than you think.
Bambi (1942). Bambi's mother is shot dead by hunters when she and her son are looking for food in the winter snow. A whole generation of kids was traumatized. Now, movies for kids should not be all sanitized pink happy affairs. But the death of a parent is quite disturbing to any six-year-old. This one is fairly famous for all the denial associated therewith. It gets worse. Originally, Bambi was going to go back later, and find his mother lying in a pool of blood, but the idea was scrapped, both because it was too cruel and because it wouldn't make sense for a hunter to score a deer and then just leave it in the woods.
Fantasia: "The Rite of Spring" featured an epic dinosaur battle where the viewers are treated to the delightful spectacle of a T-Rex (who is little more than a jaw full of knife-like teeth and a pair of mad red eyes) strangling the life out of a stegosaurus under a storm-filled sky. Later, all the rest of the dinosaurs slowly starve to death as they march through an endless desert.
Subverted at the end of The Jungle Book, where at first Baloo appears to have died a gruesome death at the hands of Shere Khan, but then it turns out that he survived.
The Horned King is absorbed into the cauldron as his clothing and flesh are sucked into the pot, and finally explodes as a disturbingly smiling skeleton.
Scenes of the Cauldron Born tearing apart the Horned King's living minions were cut to keep it from getting an R rating.
In The Great Mouse Detective, after a drunken henchman calls him a rat, Prof. Ratigan (who insists on being thought of as a "really big mouse") feeds the hapless minion to his enormous (by mouse standards) pet cat. This is shown by having the henchman just sitting on the ground, singing to himself, as the cat walks up behind him, picks him up, and...gulp. He didn't even see it coming. (Granted, he was drunk...). It cuts to a shot of some of the other henchmen taking off their hats, one even shedding a few tears, while Ratigan wipes his precious kitty's mouth with a hankie and asks if she enjoyed her tasty treat- the 'treat' in question being of a species HE claims to be!
Sykes and his two Doberman cronies from Oliver & Company, especially the ending where the dogs are knocked off the speeding car onto the subway tracks and electrocuted to death, followed by Sykes plowing head-first into the train. It's telling to note that they switched to the "Villain Falls to His/Her Doom" ending for years after this.
The original draft of the above scene originally had Eric wrestle the trident from her long enough to "oblige" her when she demands he give it back... by tossing it right through her heart (This scene was Re-used in the second Kingdom Hearts game).
During the castle invasion scene the wardrobe jumps off a second story balcony on to a guy. This is a comedy fight so you normally wouldn't think about it, that is until we cut back to see the wardrobe fighting someone else with the mangled corpse of the guy she killed on the ground...
There's also the Beast's death after being stabbed in the back by Gaston (who falls off the roof into a canyon seconds later), the placement of the wound and the way he struggles to breathe makes it clear he has a punctured lung and slowly bleeds to death in Belle's arms (an agonizing way to die). It's okay, though, he got better.
It was also originally intended that Gaston would have suffered this trope: Specifically he would have survived his fall, albeit with a broken leg, and ended up encountering the wolves from earlier. Apparently, they felt it was too gruesome even for someone like him. This specific death does end up getting used with Scar and the Hyenas, however.
Aladdin: The Return of Jafar. After face-turned Iago drops Genie Jafar's lamp into some boiling lava, to quote someone else's description of the scene, "He gets all these shocks like lightning through him for at least a minute or two of film, showing his skeleton, his face in agony, screaming and crying for a long time, burning, and then explodes into ashes." Ironically, his final death (at the end of a crossover episode with Hercules) had him dragged back to the Underworld after Herc and Aladdin broke his staff in two (according to Hades, it's the only thing that can keep Jafar out of the Underworld as much as he wants).
Mufasa's death; watching him fall, screaming to his death while his son watches is bad enough, but then we have Simba's repeated pleas for him to "wake up, Dad" while desperately nudging his corpse is simultaneously the most shocking and depressing moment in the entire movie.
The fight between Simba and Scar ends with Scar being eaten alive (or at the very least being mauled to death) by his hyena henchmen (cast in shadow, but still!). The sequel makes it even worse by implying that he might have been burned to death as well.
The Lion King II: Simba's Pride had Nuka die by being trampled by logs because he wanted to show off to his mom, since he wanted her appreciation. Zira fell to her death after refusing help. In a deleted scene, she committed suicide. The fan-base is divided on whether it was best to change it.
In The Hunchbackof Notre Dame, Judge Frollo falls to his death off of a crumbling gargoyle and into a pit of molten copper. It may be clouded by smoke, but it is certain that he died from the impact only to have his corpse immolated. Not to mention there are strong implications that this was the result of divine intervention.
Mulan had Shan Yu blown to bits by several fireworks lit by Mulan and Mushu.
Kerchak and Kala's infant son is a little too energetic and curious for his own good when he chases a frog while his parents sleep, and he runs into the leopard Sabor. Sabor pounces on him and the movie cuts to his devastated parents' reaction when he shrieks as Sabor kills and devours him.
We see the mother ape happen upon the treehouse Tarzan's family built. She goes in curiously and we find it a bit too quiet. She soon see why, the place has been trashed and the bodies of Tarzan's family are seen next to a set of bloodied pawprints on the floor.
Clayton get tangled up in a cluster of vines high in the trees, and then proceeds to cut his way out of them, all the while the vines are tightening around his neck. Unfortunately for him, he cuts one too many vines and falls to his death. While the film does cut to a Gory Discretion Shot, lightning flashes and we can see Clayton's hanging silhouette on a nearby tree. No wonder why it's the most disturbing death seen in any animated Disney film!
Carnotaurus, before attacking the nest Aladar's egg is located in, actually mauls a Pachyrhinosaurus to death.
At the end, Kron as a result of him not listening to Aladar ends up climbing a dangerous ravine and is mauled to death by the Carnotaurus.
Bruton's is even worse. He gets stuck in a cave-in, and struggles to run out while boulders crash down on him. Finally he buried, and Aladar uncovers him only for Bruton to twitch a little, then die.
They cut fairly quickly from the carnotaur's corpse, but the lighting makes it look like it was ripped in half from the fall.
Atlantis The Lost Empire has [spoiler: Rourke is turned to crystal and shattered to pieces by propeller blades. Although some might overlook this compared to how graphic it would have been if he hadn't been turned to crystal.]]
At the very beginning, Sitka, Kenai's oldest brother is killed in a fight against Koda's mother, who she corners on a glacier, and as she is about to go after Denahi and Kenai, Sitka performs a Heroic Sacrifice and uses his spear staff to break the ice, causing the glacier to collapse into the water below. His antlered hood and his totem pendant are all that is found by his brothers, who were desperately searching the water for him.
Later, Kenai as revenge for killing his brother, actually goes after Koda's mother, and stabs her to death, prompting Sitka's ghost to turn Kenai into a bear as punishment for his wrongdoings.
Dr. Facilier is dragged into voodoo-hell — screaming and struggling— by his "Friends on the Other Side" when it's apparent his plan to pay off his "debt" to them is foiled for good. His gravestone, oy. It's even worse if you look at how they animated his eyes during that scene. Most Disney villains meet their end with a little gasp and a look of surprise or a Big "NO!"; as Facilier reacts to his talisman breaking with a Little "No" followed by a Big "NO!", you can see him realize clearly before his friends even show up that he is about to die horribly. Even to adults, it's incredibly unsettling to watch the man have a Villainous Breakdown and beg for his life as his "friends" kill him. Even Tiana is visibly horrified as she watches.
Plus, Ray being stepped on. Really not the kind of thing you expect in a Disney film, especially with it ultimately subverting the Disney Death trope.
King Candy A.K.A. Turbo gets eaten alive by a Cybug. That's pretty Family Unfriendly right there, but then it turns out one family unfriendly death is not the end for him and he goes all One-Winged Angel. Fortunately, Ralph defeats him (as well as all the other Cybugs) by causing the Diet Cola Volcano to erupt. Since "Turbo" is now just a Cybug with Turbo's memories, the Cybug's programming takes over and he starts flying into the geyser. Last thing we see of Turbo is him glitching between a hypnotized "King Candy" and his real face, which is screaming in horror as he flies into the geyser and immolates himself.
King Candy manages to convince Ralph that, if Vanellope is promoted to playable status, the players will see her glitches and assume the game is broken, forcing the arcade to decommission the machine. While player characters and NPCs will manage to evacuate safely, glitches like Vanellope won't, and will get sucked alive into a painful black hole of deletion, along with the game environment.
Toy Story. That poor action figure Sid blew up during his introductory scene in the first film, therefore making him the only character in the series to be killed off permanently.
Hopper's end in A Bug's Life. Lured near a bird's nest, grabbed, then presented to the bird's babies as they gather under him chirping in anticipation with him screaming all the while. Granted it's nature, but still....
In The Incredibles after Mr. Incredible tosses a car at Syndrome causing him to go flying into the engine of his jet plane where his cape gets caught in a propeller and he is slowly pulled into the engine and chopped to pieces (granted the moment of death was off-screen it was still pretty gruesome to think about). Earlier in the film, Edna Mode listed a number of superheroes who had met their untimely demise on account of their capes getting hung, one of which just so happened to get sucked into a jet engine. Anvilicious foreshadowing. Even more so when you realise that it means that little bits of flesh and blood and bone would be raining down over the neighbourhood for a few minutes afterwards. Also, every time a hovercraft exploded with a Mook inside.
GO-4's death. We're shown how sentient and cute robots can be. Then one of them falls a few stories and smashes on the ground. Evil or not, it's still amazingly graphic for a robot.
It may have been a Disney Death, but seeing WALL•E getting quite graphically crushed in one, swift motion was pretty cringe-worthy.
The steward bots that try to prevent WALL•E's group from getting to the holo detector. One of them gets blasted by EVE, one gets defibulated to death, and the rest get smashed into scrap metal after WALL•E cuts the restraints on the massage bot.
In Agent Cody Banks, the main villain's head is eaten/melted by raging nanobots which escaped from an icecube placed in his mouth. Since this was a Family Movie, only part of this was shown.
One of the many elements that mirrors The Tuxedo, in which the main villain has the queen water strider (bugs that make water dehydrated) thrown down his throat, and the other bugs fly down his throat, causing him to grotesquely shrivel up.
What about the way those villains die? One is crushed between two cars, and the main one is stabbed through the stomach by a pane of broken glass.
Snape's death scene in Harry Potter and the Deathly Hallows Part 2 is even more graphic than the book, with Voldemort slashing Snape's throat open with Sectumsempra then having Nagini finish him, with blood splattering on the walls. And this is coming from filmmakers who cut Wormtail's death scene due to "suicide" (which it technically wasn't) being too "graphic."
It's debatable as to which is more graphic. In the book Nagini bit him several times and, while no blood is specifically stated to have splattered, it did gush from his mouth, ears, nose and eyes, along with the memory that Harry has to collect and put into a phial for evidence. And there is a discretion shot in the movie.
From the same film, Bellatrix's death. In the book, Molly simply hit her with an unidentified spell that killed her instantly. In the film, a spell causes her corset to tighten (likely crushing her internal organs and ribs) and is hit by another that blows her into embers.
The Hunger Games has its share of this. The tracker jackers are probably the worst.
Jack the Giant Slayer: Fallon has a beanstalk grow from within him, causing his body to burst and send giant chunks of him flying. Also, several humans are either crushed under foot or have their heads bitten off.
The Lone Ranger: The Lone Ranger's brother has his heart cut out and eaten by Cavendish. It's a Sound-Only Death as all we can see is John's horrified Reaction Shot, and the audience only have their imaginations and the earlier rumors of Cavendish's cannibalism to guess what's happening.
An infamous deleted scene from The Mask was going to have the Big Bad kill Peggy by crushing her to death using a printing press instead of Stanley Ipkiss after the latter is forced to give up the titular Mask so that the villain can become the Mask himself. Peggy then emerges out of the printing press as a newspaper written entirely in red ink, has a picture of her screaming, and is entitled "Reporter Killed in Freak Accident."
Merlin's Shop of Mystical Wonders, featured in Mystery Science Theater 3000. During the course of the movie, Ernest Borgnine relates trauma-inducing stories to his young, wide-eyed grandson — stories which include the death and immolation of innocent animals; evil, possessed monkey toys who rain death and hellfire on all around them; old ladies being killed by lightning, and worse.
While being hilarious at the same time, Captain Amazing and Casanova Frankenstein's horrific mutating deaths in Mystery Men were something that would keep you awake at night.
Oliver! has the death of Nancy. Not only was she one of the nicer characters, her death was the result of cold-blooded murder at the hands of her boyfriend. Specifically, he beats her viciously with a club. There is a discretion shot, but you see the club being repeatedly raised and brought down, while you can hear Nancy scream in absolute agony.
Later in the film, you see Bill shot while tying a rope around his waist on a roof. His body then swings around in the air. Granted, this was toned down from how he died in the book, but still.
Raiders of the Lost Ark: The decompressing/melting/exploding faces from the finale (Belloq's face explosion was considered too graphic by the ratings board that it had to be partially obscured by a column of fire; not to mention all the Nazi soldiers get zapped by the power of God ("or something"), including one suffering a direct hit in the eyes) and the huge German soldier who gets a little too close to the plane propeller.
If you think the movies are bad, then look at the comics. Indiana Jones and the Fate of Atlantis has the God Machine victims (the villains who use the machine to achieve immortality). The end result is the twisted combination of face melting and Body Horror. It makes Raiders look like Pokémon by comparison. This was in the Adventure Game version, too.
The Iron Phoenix has Indy and one of his companions captured by a cult of Druids. They kill the companion by splashing a potion on him that makes vegetation gorily erupt from his body. Indy escapes by dumping the potion on the Head Druid.
The sacrifice scene from Temple of Doom. First a poor sap is strapped to a metal grid and gets his heart slowly torn out by the evil priest. Then, while 'still alive'' (the beating heart in the hand of the priest), he gets flipped over facing the ground. A trapdoor opens, releasing smoke and red light reminiscent of hellfire. Then he gets lowered into the lava below, and just as he's about to be dipped, the camera switches to the priest's hand; where the heart suddenly ignites and burns to ash as the victim dies. Did I mention that he screamed all the way through the scene?
There's pretty much two of these in each of the original trilogy. One for the gruesome death of the Giant Mook (chopped up by the plane's propeller in Raiders, crushed under the roller in Temple, can't-be-arsed-to-remember-what in Crusader) and one for the supernatural nastiness that invariably shows up (The melting faces in Raider, the pulling out of the heart in Temple and the rapid aging of Donovan in Crusader).
Pretty sure nothing happened to the guy's character in Last Crusade, unless Vogel had him executed for laughing at him when he got pitched out of the zeppelin by Indy.
Don't forget the death of the Nazi commander in The Last Crusade, where the tank he's sitting in the cupola of rolls off a cliff, and we can clearly see his ragdoll-like body being tossed about and bashed against the rocks as the tank bounces to a stop. Earlier, one mook is tossed onto the exposed treads of the tank and promptly rolled to the front like on a conveyor belt and crushed. In Raiders, the driver of the truck carrying the ark was thrown out the front, and we get a view of his body twitching and flailing as the truck runs him over.
1985's Return to Oz has the witch trying to take Dorothy's head, and the desert that turns you into sand.
Who could forget the Nome King, though, who, after swallowing an egg, which is poison to nomes, sloowly falls apart, eventually becoming a skeleton-like stone before collapsing entirely? And his human-like eye turns into a rock, giving him a creepy blank stare as he's dying... It's no wonder they cut this scene down when it was on TV!
And of course, the Clones don't exactly have the most favourable deaths either. One that stood out was after his space fighter is destroyed, we see the Clone pilot's lifeless body floating in space amid the wreckage of his craft.
We see the Wampa devour Luke Skywalker's Taun-taun.
Jabba's Rancor. Unless you happen to be a Jedi, you ain't getting out of that pit alive... or in one piece (the Rancor bites a guard in half before swallowing him). We get to see this happen to an unlucky Gammorean guard. The same thing happens to a Green-Skinned Space Babe earlier, although they don't show it, we just hear her screams.
Darth Maul's death in Episode One, he gets sliced visibly in half by a lightsaber.
Rumor has it that the infamous decision to have Greedo shoot first was "necessary" to preserve the film's PG rating. Han's unflinching first strike was apparently PG-13 worthy.
Scrooged. The Bill Murray Christmas Carol movie, yes. It's creepy enough when Frank, down in the sewer after he's had his visit with one of the ghosts, finds the frozen corpse of the bum holding the wristwatch, but not as bad as Frank's coffin being fed into the crematory with him "alive" inside it.
This "graveway to hell" sequence may have been borrowed from the Albert Finney musical version 13 years earlier. But, as Charles Dickens himself says in Muppet Christmas Carol, it's all right — this is culture!
Averted in Spider-Man 2, with the death of Mrs. Octavius. Jagged glass flew at her at incredible speeds, and yet Otto found an intact, wholly recognizable body. On the other hand, while the exact fate of the last nurse Doc Ock dragged under the table is not shown, one has a feeling she isn't screaming in fear of being knocked out.
Played oh so very straight in the first movie. When Green Goblin throws one of his pumpkin bombs at the bystanders, they get disintegrated into skeletons.
The film had its fair share of gruesome deaths. Bonecrusher and Frenzy both getting beheaded (in Frenzy's case, by his own weapon), and just look at the mess of what was formerly Megatron's chest after the Allspark is rammed directly into his spark.
How bout that soldier in Lennox's squad who got impaled in his chest by Scorponok?
And Jazz's death.
Jazz: "You want a piece of me? You want a piece?!"
Megatron: "No! I want-" *tears Jazz in half* "TWO!"
Ravage's death at Bumblebee's hands-in slow motion his SPINE is ripped out, goo hanging off it, then used as a club. Or even Grindor's robo-brains spraying all over the forest when his head is ripped in two by Optimus.
And Jetfire crushing Scorponok's head flat with his fist. Devastator being blown into at least a dozen pieces by the railgun.
Highlights include Ironhide getting shot in the back with a Cosmic Rust gun and crumbling into dust as he writhes in agony, Laserbeak murdering humans left and right, Megatron's head getting split with an axe before being yanked free of his body with his spine still attached, and finally, Sentinel Prime being shot in the face while he's down, gangland execution-style.
Que/Wheeljack's death, execution-style. Complete with rolling severed head. And before he was executed, he begged for his life.
There is also Starscream being blinded when both of his eyes are ripped out and then his head is blown up by a grenade dropped into one of his now empty eye sockets, Soundwave having Bumblebee's arm cannon shot up through his chin and out the top of his head, and Shockwave becoming the newest member of the Decepticons whose faces have been ripped off by Optimus Prime club.
Then of course, there's the Wreckers tearing a helpless Decepticon limb from limb.
Decepticons KILLING HUMANS. You see corpses of people who were probably commuting on their way to work in train carriages. Humans being skeletonized by Decepticons.
Watching him get run over with a steamroller wasn't exactly a fun thing to watch either. It may not have killed him, but we didn't know he would survive, and his agonized wails didn't exactly sound like "No worries, I'll be fine!"
There was a scene earlier in the film where Doom callously picks up an innocent toon shoe nuzzling his ankle and slowly and tortuously dips it as it whines in terrornote and that he dipped it in mouth first so that it couldn't scream, but its muted wailing and its eyes still managed to convey its pain quite well, thank you, until nothing is left but a smear of red paint on his rubber glove.
