Death Fic

A variety of fanfic in which the plotline is focused around the reactions of the cast to the death of one of their number. Frequently written in the first person, as the narrator goes on (sometimes at exasperating length) about everything they regret doing/not having done and everything that ever went wrong in their relationship to the deceased. Confessions of hidden love, secret friendship and occasionally responsibility for the death are common. Almost stereotypically ends with some variation on "Goodbye (name), life will never be the same without you/I'll miss you/I'm coming to join you just as soon as I open this vein."

This is a fanfic style which lends itself, predictably, to incredible amounts of Wangst at times.

Some Death Fics explicitly employ a Tomato Surprise by obscuring just who is narrating and/or who died until the very last moment. A few of these don't actually spring the surprise, instead forcing the reader to guess.

Not to be confused with a Dead Fic or Someone Has to Die.

Anime and Manga

 * Ranma ½:
 * Sent up hilariously in Gary Kleppe's Ranma Is Dead.
 * Done perfectly straight by Reid Carson's Elegy For A Golden Youth.
 * Random1377's Neon Genesis Evangelion fic Aoi starts with Rei having to kill Shinji (perfectly justified under the circumstances) and spirals into the abyss from there.
 * The infamous Lucky Star Death Fic Ahoge by Zokusho.
 * For Descendants of Darkness, there's the fic When the Day is Bright. Unusually, this actually has a happy ending, which only adds to the feeling of catharsis after this fic has wrung you out completely.

Film

 * Akallabêth is one for Inception that kills . Also features a very effective Downer Ending, even not counting the death.

Live-Action TV

 * There is, of course, this amazingly vindictive and far-too-detailed monstrosity about Barney the Dinosaur.
 * iCarly: One exponent is Lovely Amelie who has written several of these, including Castles In The Air, Up Into The Blue, and Days Like Masquerades.
 * One example of this in the BBC Sherlock fandom is a one-shot, Alone On the Water, told from John's POV as he watches Sherlock slowly die from terminal brain cancer.

Music

Video Games

 * Go Not Gently kills off Vivi Ornitier in the prologue. His death shapes the entire plot from there on out.

Western Animation

 * Parodied (amongst other things) in the Kim Possible oneshot Not Another Death Fic. In a nutshell: The characters try to avoid turning the story into a Death Fic...by turning it into a Shipping fic. Hilarity Ensues.
 * The unusually dark My Little Pony: Friendship Is Magic fanfic Bittersweet had Pinkie Pie get diabetes, and going on one last sweet binge because she couldn't live with it. Rainbow Dash runs away because she can't deal with everything in Ponyville reminding her of Pinkie, while Rarity tries (unsuccessfully) to resurrect her.
