In Elfen Lied, Kouta's sister Kanae is cut in half by Lucy when she knows about Lucy's powers and attempts to save her older brother, but he hits her and calls her a liar. Her death causes said brother to be traumatized for life. This was really one thing that made several fans hate Lucy, and made others swear off the series as a whole - killing Kouta's family over a little lie about who Kouta was taking to an event...
It's actually a standard way for the Diclonius to kill their victims. Lucy and Mariko are specially fond of it.
This is also how Dante disposed of her latest apprentice.

This is the fate of Rurouni Kenshin villain Uonuma Usui, torn in half at the waist by the force of Saito Hajime's point-blank Gatotsu in the manga.
He was merely impaled in the anime, which is a huge step down from the manga scene, which is pretty much outright gorn. You can see Usui's intestines hanging down and everything. The Toonami version edited the scene further so that he wasn't even impaled, just sliced bloodlessly.
This is the standard demon slaying procedure in Claymore.
As well as being Dietrich's MO for dealing with Awakened Beings, it's how Flora dies. Clare also suffers this before being absorbed into the Destroyer. Deneve gets cut not quite in half.
Ichigo's über-Hollow does this to Ulquiorra in Bleach. Rather confusing, since he did it with a cero aimed at Ulquiorra's head. Ulquiorra gets better just in time to return Ichigo back to normal, but it doesn't last very long. Ulquiorra, that is.
Grimmjow incinerates Luppi's entire body from the waist up. He also does the same to Menoly earlier on, though she gets better.
Aizen attempts this on Ichigo, wanting to split him in half without obliterating his body, and held back a little too much, leaving half of his hip still attached.
Yamamoto does this vertically to Allon, although not even this completely deters him.
Orihime's first (and so far, only) successful use of Tsubaki cuts Numb Chandelier in half vertically.
And in the manga, this is the fate of Hidetomo Kajomaru, sliced in half at the bare hand (literally) of Haschwald from the Vandenreich. He's not the only one: Dark Action Girl Bambietta Basterbine cuts down several others in half with her sword.
In the manga, this is the fate of Yamamoto. Not convinced even this was enough, Juhabach then chops off Yamamoto's swordarm and then proceeds to nuke his corpse.
In 559, we have Cang Du from the Vandenreich. He is executed by Haschwalth for having lost against Hitsugaya; uncommonly for the "vertical" version of this trope, his head is intact and he's bisected from the shoulder down.
Stroheim is bisected at the waist by Cars in the second arc. Being a product ofNAZI SCIENCE it doesn't bother him terribly.
Also happens to Diego Brando after being run over by a train in a recent chapter of Steel Ball Run.
In YuYu Hakusho, Kuwabara tries a vertical cut on Elder Toguro at the start of his fight with him, only to find that he cut a fake body, and that Toguro had used his flexibility powers to burrow into the ground.
And in chapter 601, Madara rips Tsunade's torso in two with a giant tree. Her advanced medical jutsus and Karin being around to heal her just in time are probably the only reasons she is still alive.
Used by Maka and Soul several times in Soul Eater. Stein does it Medusa, who is able to survive by possessing a snake and then "borrowing" the body of a little girl.
Happens to Buggy the Clown a lot in One Piece, as well as most Logia users at some point, often repeatedly as these characters have no problem putting themselves together again.
Trafalgar Law can do it non-lethally to other people as well, as he did to Tashigi in Chapter 661.
In Chapter 687, Zoro cut Monet in half vertically. She survives due to being a Logia user, but because she knows Zoro could have easily killed her, she is too scared to put her body back together right away, allowing Tashigi to finish her off easily.
This is the final fate of Aki Honda in Narutaru, to the point of Fan Disservice. Her death was so utterly violent, (I mean, before being cut, she gets raped with the same dragon claw that ripped her in half!), that it was cut out in the international versions of the manga.
Occurs in MPD Psycho when a character named Kido goes up against a subway train. The results are, needless to say, quite gruesome.
Almost immediately afterwards, Quartum gets chopped in half by Negi after he sees that Quartum did this to Chachamaru.
The demon panther in Magical Girl Lyrical NanohaThe Movie First that served as the second Monster of the Week found itself bisected horizontally after Nanoha lanced her way through its body. It wasn't enough to kill it though, and its upper half quickly escaped into the sky... until Fate chased it down and applied the vertical version of this trope, destroying its body.
In the horror mangaRegion, when Kanon's ankle is grabbed by a man who is pleading for help, she is horrified that everything below the man's waist is covered with rats, happily gorging themselves on what little remains of his flesh.

In Franken Fran, this happens to the assassin Agito in Ch 18(he got better thanks to his Healing Factor), and Fran herself gets cut in half bilaterally by accident in Ch 60. She also gets better...eventually, after turning both halves into complete but half-brained persons.
In End of Evangelion, during Asuka's frantic battle against the Mass Production EVA Series, she severs the fifth one she attacks at the waist, sending the top half flying. All nine recover from their injuries and counterattack, but how this particular EVA managed to piece itself together after being so torn asunder is handwaved.
There's also Misato's brutal death. If you pause just as the JSSDF charges explode, you can see this.
Happens occasionally in Fist of the North Star. Several of the martial arts schools have techniques which involve cutting, so this is inevitable. Nanto schools especially feature this, but so does Gento Koken. The anime is notable for showing Kenshiro doing this, cleanly and effortlessly bisecting a man vertically with the edge of his hand. Making this all the stranger is that Hokuto Shinken focuses on hitting Pressure Points to cause people's heads (and sometimes the rest of them) to explode.
Given that Attack on Titan involves giants who indiscriminately eat people, it shouldn't be surprising that this happens fairly often.
During a lighthearted moment, Eren accuses Franz and Hannah of being married, which they vehemently deny. A little later on, we find Hannah desperately giving CPR to Franz. Then, the camera shifts position, showing that Franz is missing everything from the waist on down.
Marco Bott is missing the right half of his head and torso when found, and no one seems to have witnessed his final moments. It results in a low-key Freak Out for Jean, and sets off his major Character Development.

However, he decides he still needs her and puts her back together, for her to later do this herself to Tarsil.
Pictured atop this place, Dr. Loveless from Wild Wild West. This happens before the movie itself takes place. Punned repeatedly by Jim West (and himself, as the quote below the picture shows), including using the name of the trope.
In Beetlejuice a woman in the afterlife waiting room is separated at the waist, but still able to move both parts of her body. (An example of Jacob Marley Apparel that is common in the film. Apparently she'd been a magician's assistant in a 'sawed in half' trick gone wrong.) A hilarious scene involving her is shown at the end of the movie when the title character strokes her leg, and her upper half - who is "sitting" on the other side of him - angrily hits him with a magazine.
Happens when Ben Moss gets caught between two glass doors slamming shut in the remake of Thir13en Ghosts.
The bugs in Starship Troopers have a fondness for this trope, being giant insects. Carmen's commanding officer gets herself cut in half by a descending bulkhead door.
Walk Hard: The Dewey Cox Story: The major source of angst in Dewey's life is the fact that he accidentally halved his brother with a machete when they were little. His father shouts, "You're not half the boy Nate was. You're not even half the boy that the top half of Nate was after you cut him in half!" He is eventually forgiven by his father after the old man accidentally halfs himself while trying to kill Dewey.
Happened in Freddy vs. Jason to one of the supporting teens; having been possessed by Freddy, the teen stares down a stalking, pissed-off Jason and looks seemingly defenseless — until he jabs two syringes full of tranquilizers into Jason's neck and injects him with the full dose. Unfortunately for the teen, that's his last act as a living person; before Jason's lights go out, he uses his machete to cut the teen in half.
In the most horrific scene from The Hitcher, psycho killer Ryder ties the love interest, Nash, between a Mack truck and its trailer, commandeers the cab, revs up the engine and threatens to rip her in half if he doesn't speak to Jim, the protagonist. The police enlist Jim, whom they had previously suspected was the killer, but are now convinced of his innocence, to try to negotiate with Ryder, but when Jim confronts him, Ryder orders him to shoot him. Jim refuses because Ryder's foot is on the clutch and if it slips off, Nash will die anyway. Ryder gets pissed and insults Jim, then shifts the clutch and the accelerator, resulting in Nash getting ripped in half before Jim's very eyes.
Well, not literally, as Jim wasn't able to see what was happening at the back of a truck he was sitting in. Nor does the audience see Nash's demise, just her bound wrists as they're pulled hard against the ropes, then go slack. The remake did show someone torn in half this way, but it wasn't the girl and wasn't very convincing.
During the Crazy 88 sword battle in Kill Bill the Bride hands this out to one unfortunate Mook, who is split in half right down the middle with her Hattori Hanzo sword.

In Paranoid Park, the main character hops onto a train and scuffles with a security guard who catches him. However, the guard loses his footing and falls onto a second set of tracks as another train approaches. The result is an unnerving scene in which the guard crawls away from the tracks, minus the lower half of his body.

In the opening action sequence of Transformers: Revenge of the Fallen, Sideswipe does a balletic jump over the Audi R8, Sideways, lands in front of him and grounds his built in sword blade so that as the Decepticon drives forwards he cuts himself in two lengthways.

In the climax of the first film, Megatron does it to Jazz, quipping that he doesn't want "a piece" of Jazz, he wants two.
Played straight then immediately reverted in the finale of Blade when he chops Deacon Frost in half, but the upper body only separates a few inches before his vampire god powers (and a lot of blood) pull the parts back together again.
Also done to a vampire in the sequel, except this cut was vertical, and it successfully killed the vampire.
In the "Weird Al" Yankovic film UHF the TV show preview for "Conan the Librarian" depicts the barbarian chopping a patron in half, vertically, for returning books past their due date.
Happens to one guy in Slither. Subverted in that his organs fall out before he splits in half.
Hud in Cloverfield. It's a blink and you miss it moment, but if you watch closely, the monster swallows his legs, letting the upper body fall to the ground.
Apparently in the backstory for a background character in Corpse Bride — when Victor first encounters him, he splits in half vertically to get around the young man.
Every single person, except for the little girl, in the opening scene of Ghost Ship. The only reason she survives is because she's still short enough that the high-tension cable goes over her head instead of through her body as it cuts across the deck in a split-second.
For at least one on-screen killing. It's implied that the messes he usually leaves behind are a lot worse.
Happened some time ago to a character in the Doom movie, when a teleport-pad accident sent his upper and lower halves to different destinations. Due to futuristic medicine, he lives, but as half a body permanently attached to a wheelchair/life support system.
A nonlethal version happens to Ronald Reagan in King's Row, in which he wakes up from surgery and says the famous line, "Where's the rest of me?" Reagan, by the way, plays a notorious playboy who had taken an interest in the surgeon's daughter. Think about it.

A favored fatality of the Saw franchise, several victims are usually decapitated in this manner. One victim is strapped to a bench and disembered by a razor sharp pendulum. In the last installment's introductory sequence, the girl who is cheated on the two men in the contest is dropped forcefully upon a rotating sawblade when they agree that she is the one to die in the trap. The real Gorn candidate, though, is the suspension trap that forcefully rips the victim in two vertically when it goes off.
Happens to one of the Rangers in Saving Private Ryan during the Omaha Beach landing sequence. Captain Miller is dragging a wounded comrade out of the water when a mortar explodes nearby, throwing Miller to the ground. When he gets back up and resumes dragging, the soldier is now dead and has been blown in half.

Happens briefly in Highlander III: The Sorcerer, when Connor cuts Kane in half horizontally. But then he uses his powers to join the halves and the fight continues.
In Captains Courageous: It happens when the Portuguese fishermansuffers an accident while deep sea fishing. Because he was submerged up to his neck in the ocean, his wounds were not visible. He announced his predicament through an interpreter, so the boy he had been taking care of wouldn't know how bad it was.
A disguised Corran Horn uses the same technique on a 3PO unit belonging to the Blackstar Pirates in I, Jedi as part of a dramatic display meant to frighten them.
Lightsaber combat refers to this technique as sai tok. It's Sithly in nature (even when it's necessary to kill, a Jedi shouldn't feel a desire to mutilate his enemy's body), hence Jedi almost never use it on sentients. Jedi Master Cin Drallig, however, expresses the opinion that when fighting a Sith Lord, no technique should be considered off limits to stop the threat they represent.
Before that, Odetta loses her legs thanks to Jack Mort pushing her in front of a train. Later, Roland possesses Jack's body and makes him do it to himself-except aims the impact point just a bit higher.
Interesting variation in The Cloven Viscount by Italo Calvino: the title character is a nobleman who got cut in two (vertically) during a fight against Turkish forces. But, amazingly, both halves survive, one evil and the other good.

This is taken to a strange extreme in Deathstalker: The character 'Half A Man', a former investigator, is sliced in half vertically, the missing half of his body replaced by a sinister energy being. Eventually, that side devours him, and he's well aware that it's happening for quite some time.
Genome begins with protagonist leaving a hospital where he recovered after being bisected. His legs had to be regrown for several months, since the ship where the accident happened had only one spare medical chamber and thus only one half could be saved; otherwise, legs could just have been reattached.
Uncle Marty in the first episode of Harper's Island, as well as Beth in a later episode.
The first one happens in particularly gruesome fashion: he falls through a sabotaged foot bridge, and while he's struggling to pull himself back up, the killer hacks him apart from below with a big knife. While he tries to shoot him through the bridge. It looks for a minute like he might win out, but ... no. Many episodes later they find the bodystrung up in a tree .. in two pieces.

He pretends to have a twin brother, and further pretends that they are both traveling salesmen, and marries each of them in separate ceremonies. Understandably, the twins are Not Happy when they discover the subterfuge, and proceed to execute their own version of Solomon's Judgment. With a chainsaw. In the end, each twin has half, and both are happy. Him... not so much.

Anya meets the same fate in the final episode. Not from the groin up, though.
In 1000 Ways to Die: The first case featured in the series ever was this.

Native american legends tell of Odzihozo, a giant who was so impatient during his creation that even when he was not yet fully made, he set out on a quest to change the world. However, he had only half a body with no legs at that time, and as he dragged his body around, he created valleys, lakes, and rivers in his wake. Eventually, after hauling and heaving himself across the continents for centuries, he was so exhaused that he crawled up a hill and stayed there forever, and seeing what he had done, he turned himself into a mountain so that to this day he admires his creation. Or that of his behind, actually.
That makes him more of "Half The Man He Was Supposed To Be."
One Eskimo tale tells of a beautiful bride desired by two brothers. Unable to decide who should have her, they each grabbed her from an end and pulled, result in one having the upper torso and other the hips and below. Being clever artificers, they quickly carved out a wooden replacement for the missing half, thereby explaining why the women of one tribe were so clever with beadwork (having been descended from the woman with the living upper torso) while the other tribe excelled at dancing (having been descended from the woman with flesh legs).
Another story implies this. Two women came to King Solomon, each claiming that they were the mother of a particular baby. The king thought about it for a while, and then came to the decision that the baby should be cut in half.

A lot of the Warhammer 40,000 backstory has this, usually about Space Marines. Particularly about World Eaters. And ESPECIALLY about Kharn the Betrayer, whose axe, Gorechild is stated as capable of splitting an armoured space marine from crown to crotch, or something along those lines.

Done inMacbeth where the titular character is reported to have sliced Macdonwald "from the nave to the chaps" right before the play begins. This is done to establish right away how bloodthirsty MacBeth is.
Johnny Eck, a sideshow performer born without a pelvis, was billed as "Half-Boy" because his truncated body resembled this trope's outcome. At one point, he and his normal-looking twin brother worked with a magician to subvert the usual Saw a Woman in Half routine: his brother would "volunteer" to be bisected on stage, the magician would covertly switch the twins while pretending something had Gone Horribly Wrong with the trick, after which Johnny would run around the stage on his palms, shouting that he wanted his legs back.
The Axe Lord strikes the Goblin Maceman in the lower body with her =steel battle axe= and the severed part sails off in an arc!

Very common in Mortal Kombatfatalities. Usually a horizontal cut, as it's easier to animate, but Kung Lao can do vertical cuts in a few games.
Also, story-wise, this is how Sonja died in the Armageddon, as one of the first things you see in the opening sequence is her dead body, torn in half. (Who did it to her is never revealed. However, one of the few good things to happen as a result of Raiden tampering with the timeline is, she becomes one of the survivors in the new reality..
Simlarly, this also happens in the Clay Fighter games as a "Claytality". Since this is supposed to be a parody, it's nothing but slapstick.
In Eternal Darkness some of the larger swords (such as the long sword found in the church levels and Kareem's ram dao) can do this to zombies.
Wario can get cut in half vertically in Wario Land 3. Since he always comes back together as if nothing happened, it's only a minor inconvinience.
If you kill a boss with a sword weapon in Mega Man ZX, this will happen to them.
It was also used on Mega Man X2's Wire Sponge if X used the Sonic Slicer on him.

The Legend of Zelda: The Wind Waker can have this happen to Stalfos enemies, if I remember correctly, with their top half and head trying to run away from Link and their feet trying to attack him.

And it doesn't necessarily stop them coming at you...
In FEAR, you can blow mooks in half with the shotgun.
No More Heroes: Travis can chop enemies in half with the finishing blow.

With the Blade, Whipfist and Claw powers in Prototype you can slice up people in three different ways: sideways, vertically and diagonally. Or you can just grab people with the Musclemass power, and pull them in half.

Speedy Blupi/Eggbert 2 features large circular saws in some levels that can vertically (and bloodlessly) saw the title character in half (at least until he respawns, now in one piece again).
Most of the enemies in Dead Space are capable of doing this to Isaac, but with the proper weapons he can do it right back.
In Resident Evil 2', Leon can literally blast a zombie in half with a standard shotgun if they are close, while Claire can blast the legs off a zombie with a grenade round-loaded grenade launcher. And they still come after you.
In Resident Evil 4, Mendez' legs come off once down to about half-HP. The boss U-3 can instant-kill Leon via bisection with its Plaga pincers. In the earlier games, zombies could be bisected with the shotgun, but would continue to crawl after you until you headstomped them.
Pit does this to Hades via a giant energy blade three-fifths of the way through the final battle of Kid Icarus: Uprising. Unlike most examples, Hades is just barely hurt and simply grows an entire new lower half. The seam between his new and old halves becomes a valid weak spot for the next phase of the battle, however.
This is also the case with the Erinus enemy. When attacked, it splits in two with both halves coming after you.
In the many death scenes of Brain Dead 13, Lance will be cut in half (vertically and horizontally) by Fritz.
The boss Lokii from The Binding of Isaac is another boss, Loki, but ripped in half vertically. Both halves attack you.
SLAI Steel Lancer Arena International has this happen in its opening. A Carro model grabs a Proton by the neck and hoists it into the air. It shoves its machine cannon into the Proton's midsection and opens fire until the Proton's entire lower half is blown off, landing some distance away before exploding. The Carro then throws the Proton's remaining top half behind it, which explodes in midair.
In the notoriously gory Soldier of Fortune series, enemies can be bisected at the waist by the shotgun, large caliber arms, or explosives.

Command & Conquer: Tiberian Sun has Nod Cyborgs, tough infantry units that aren't subjected to the common weaknesses of normal soldiers. If they're damaged enough there's a chance they'll be blown in half, but the lack of legs merely slows them down.
The Duvalia in Resident Evil 5 finishes off the player character by devouring their upper body.
A possible result of using the Tsurugi of Muramasa on human-size or smaller opponents in NetHack: it happens on about 5% of hits, and kills instantly when it occursnote larger opponents can't be killed in this way, but take double damage when it happens. However, only Samurai can get it without wishing or bones, and have to take it from someone wielding it, and that instakill chance still applies when the player is targeted.
In The Wonderful 101, Wonder Red finishes off the first boss, Laambo, by bisecting him vertically with his own sword. Funnily enough, Laambo is still alive enough to hold his two halves together and keep shouting insults, and appears ready to continue the fight... until his sword splits in half too, at which point he finally explodes.
A death scene cut from the VGA remake of Space Quest 1 had Roger vertically cut in half with what appeared to be a chainsaw, in a manner similar to the Laura Bow example above.
A little effort and a lot of bloody-mindedness will inevitably lead to this in Toribash, where it isn't unheard of for a strong kick, a stomping attack, or even a plain old headbutt to cause an opponent to be violently torn in half at the waist or chest.
In Yousei, Dr. Johansen's body is found cut in half by the bell that crushed him. This becomes even more horrific when Kangai's kansei reveals that Johansen was still alive when Naoki and Aaron found him and that, given the time frame for the murder, he had to have been alive for at least several minutes after getting crushed before he finally succumbed to blood loss.
Miko Miyazaki in The Order of the Sticksomewhat ironically, as she kills a previous villain this way in one of her first appearances.
Feferi's dreamself got cut in half by Jack Noir shortly before the destruction of her session's Derse. Tavros' dreamself (on that session's Prospit, which fares no better) is soon afterward revealed to have been slaughtered in the same way.
And then there's what happened to Eridan...
Even before the death of his dreamself, Kanaya did Tavros the favor of chainsawing off his legs so that they could be replaced with robot prosthetics.
Jack: Happens in "One Way to Win" when half of Taylor's body is gruesomely forced out of the car by his kidnapped victim crashing into a tree.

From the Global Guardians PBEM Universe:Strength ripped one of Los Hermanos's duplicates apart by grabbing each of his arms and pulling. He then made a joke about pulling the wings off of a fly. The humor wasn't exactly appreciated.
In Starship, Commander Up reveals that this had been done to him during the Robot Wars; however, he had been bisected "vertically! hot-dog style, not hamburger style" and the missing half replaced by robot parts.

In The Fairly OddParents episode "Cosmo Rules", Jorgen caught the trick-ups and had to pass on his duties of enforcing the rules to a family member, the only available one being Cosmo. After giving Cosmo his wand, Jorgen said without it he felt like half the man he used to be. Then he hiccupped, making a magician's saw cut him in half (a symptom of trick-ups is doing a magic trick every time one hiccups). Jorgen then commented he literally was half the man he used to be.
The medical procedure for amputating people at the waist is called Hemicorporectomy - literally, the removal of half of the body. Usually done for terminal cases of pelvic cancer. It's as unpleasant as it sounds; it involves the removal of the legs, the genitalia (internal and external), most of the urinary system, the large and small intestines, pelvic bones, anus, and rectum.
The medical term for this type of injury is "transection," and the standard example is a man who fell asleep on the railroad tracks. While survival is occasionally possible, most hospital ERs have standing "do not resuscitate" orders for patients who have been bisected in accidents.
One of the nastier methods of execution used in ancient China.
Formula One driver François Cévert, while attempting to qualify for the United States Grand Prix in 1973.

Cevert's body was cut in half from his neck to just above his hip.
