Inverted by Shane Walsh who becomes the leader of the Atlanta group following Rick's death.
Reconstructed when, despite Rick's death the group continues into a harsh winter and eventually winds up in The Prison just like their canon counterparts.
The Berserkers Bride: In the show, Oswald the Agreeable went missing, Dagur only claiming to have killed him so that he could become in-charge of the Berserker Tribe in his absence. Here, he really did kill him when he threatened to break off his marriage with Hiccup for his unruly behavior.

Date A Re:Live Kills off Elliot Woodman, Karen Mathers, and Ellen Mathers during the Mukuro Arc.(Ellen does come back to life later, but dies for real after that.) In canon, all three are still alive.
Being a much darker version of Digimon Adventure 02, Digimon 02 The Story We Never Told has Wormmon being Killed Off for Real after sacrificing himself to power-up Magnamon instead of being reborn as a Digiegg (When Ken attemps to head to Primary Village, he got kicked out by the baby Digimons), the same applies to Ken himself later on in the story thanks to Oikawa.
"The Fragility of Time" does this with The Phantom Sisters, Ail (though this one is a Disney Death), Kaolinite, Eudial and Mimete (both of whom are murdered by Rubeus), Rubeus himself, and Death Phantom.
The sequel offs Fish Eye and Iron Mouse in one chapter.
Too much dawdling before going to take out Arlong results in the deaths of Chabo and Genzo.
In most Nuzlocke Comics from Pokémon Red and Blue (or the third-gen remakes), Gary's Raticate dies. This is because of a popular fan theory: Raticate's no longer on Gary's team when he asks you about dead Pokemon at Lavender Tower, so it's possible he was there in mourning. The games themselves never quite mention what happened to Raticate, though it's possible Gary just stored it in a PC box to make room for something else.
The very nature of Nuzlocke challenges is this trope. Instead of simply "fainting", any Pokemon who lose in battle are killed, and must either be released or placed in a PC box reserved for dead Pokemon.
In "Perfection is Overrated", Yukariko and Ishigami die like they did in canon, but they stay dead in this story, because Miyu is destroyed near the end of the story before she can be awakened, meaning that she cannot smash the pillars. As a result, Alyssa does not come back from the dead, either.

Aftermath of the Games: The decision for Sunburst, Starlight's friend, to die in a lab accident many years ago, was made before trailers for season six came out. Although it's subverted when it's discovered that Sunburst survived the accident, and actually ended up in the Human World instead.
This novelization ofInjustice 2has Catwoman killed by Grid in her and Cyborg's part of the story, and Grid in turn has his head smashed in by Cyborg. In the game proper, Catwoman simply disappeared after Brainiac collected Metropolis and Grid just vanished after Cyborg or Catwoman defeated him. Captain Cold, Scarecrow, and Cheetah all bite the dust in Chapter 13, and a de-powered Superman commits suicide by willingly falling to his death in Chapter 19. Chapter 9 also heavily implies that Hawkgirl committed suicide prior to the events of the story.
Possibly Cilan and his brothers, albeit it's not confirmed yet.

In a sense, this applies to Anubis in the What You Already Know series; rather than being trapped in eternal battle with Oma, Anubis is forcibly returned to his original body by Daniel (who explicitly notes that the mind of the host is gone and only the mind of the symbiote is left), and is then killed by Oma.
Fractures: With the exception of Rose Quartz/Pink Diamond and Bismuth (and a handful of others), every other Crystal Gem from the war has long since been shattered, notably Pearl and Garnet.
Both of Kallen's parents are lynched in Darwin due to the far more bloodthirsty Carine being made viceroy of Area 11 rather than Clovis.
Icarus, Gohan's pet dragon from the movies/filler, dies almost every time he appeared, and the one other time it is still deemed non-canon. The two times that he appeared in the flesh, he wound up getting eaten. He also appeared early on in the flashback of episode 10, part 3, where he exploded.
In the source material, the Garlic Jr. saga ends with him being imprisoned in the Dead Zone for eternity. In DBZA, he makes the mistake of crossing nigh-Eldritch Abomination Mr. Popo, and the Garlic Jr. saga lasts all of twenty seconds before Popo apparently absorbs his soul.
Piiza, Piroshki and Caroni get blown up by Cell before they can even land in their helicopter. For good measure, what is likely Caroni's charred corpse lands in front of Mr. Satan.

In The Plan to Eradicate Christmasnote The Abridging of the Plan to Eradicate the Super Saiyans one-shot from the video game DBZ: Raging Blast 2, Vegeta mentions that he accidentally killed his kid brother Tarble while trying to shoot down Santa's sleigh. Tarble's only appearance was in the 2009 special Yo! Son Goku and His Friends Return, but nothing bad happened to him and he returned home to space safe and sound (with Bulma even name-dropping him in Dragon Ball Z: Battle of Gods).
Similarly, Code MENT. Jeremiah dies when his Knightmare Frame explodes. The anime it was based on, Code Geass, reveals he survived after receiving medical attention.

The PreDespair Kids has the deaths of Hiyoko, Nagito, Kazuichi, and Maro (aka the Ultimate Imposter), all of whom were revealed to have survived by the end of Danganronpa 3. However, the sequel reveals that two of them are Back from the Dead thanks to the despairs.
I'd Trade My Life For Yours promises that there will be three different survivors than in canon. As such, this trope ends up happening to the three canonical survivors.
Shuichi ends up being executed in Kaede's place during the first trial.
Himiko is murdered in Chapter 3.
So far, Maki has survived, but given the premise, her death is likely inevitable.

Examples where the character died a lot sooner in the adaptation than in the source:

The fic's premise has Togami failing to prevent the first murder, resulting in Komaeda getting fatally stabbed.
To a lesser extent, Pekoyama is the victim of the second trial, rather than the killer.
Tsumiki is also a victim of the third chapter, rather than the killer.
BioShock: Right Place, Right Time, Wrong Guy: Atlas/Fontaine is killed in the middle of the story after being tricked into going into a tinkered bathysphere that breaks down as he's escaping, allowing Ryan's torpedoes to lock onto him. This is likely because since Jack was his Ace in the Hole but died before carrying out his mission. There was no use for Fontaine anymore since his gambit had ultimately failed.
In Son of the Sannin, like Hiashi above, Inoichi Yamanaka is killed in the Uchiha Insurrection, while in canon he survives until the final arc.
In What You Already Know, instead of surviving the collapse of the Goauld Empire after Anubiss final defeat, Baal is captured in a raid on his palace and is killed when he tries to take Daniel as a host a year before the Battle of Dakara.
Where Kinsey was last shown in a position that left his fate ambiguous in the TV series, here he is shot while giving a speech and clearly bleeds to death in front of a hundred witnesses.
Einar Thambarskelfir will die in 1047, three years before his historical death date.

Count Eudon dies in 1042, thirty seven years before his historical death date.

Yamcha in Future Trunk's timeline from Dragon Ball Z Abridged. Compared to the source who is killed during the Android attack, in the abridged version he dies far earlier, because he is Driven to Suicide after realizing that Bulma is pregnant with Vegeta's baby.
Captain Ginyu; in DBZ, Ginyu ends up in a Namekian frog's body and Vegeta considers stepping on him, but ultimately decides to leave him to his fate. In the abridged series, Vegeta seems to consider it, then stomps the frog anyway while declaring "Psyche! Eight for eight!"note As in, he personally killed all eight of Freeza's named minions (Cui, Dodoria, Zarbon, and the entire Ginyu Force). As a result any of Ginyu's appearances after that point are edited out. This was a Type 1 example originally, but a few years after that episode was released Dragon Ball Super brought Ginyu back during the adaptation of Dragon Ball Z: Resurrection F, only for Vegeta to kill him.
