DOOM: Repercussions of Evil is an infamous Doom fanfic and the best known work of FanFiction.Net user Peter Chimaera. The story focuses on space marine John Stalvern as he fends off a demon attack on his base that he has been expecting for years.
Like My Immortal, the story is well known and has spawned numerous parodies and dramatic readings, including a presentation using Garry's Mod, and dramatization (and hammier remake) made with The Movies. There is also a song by tomexplodes and even a Madlib. The story was eventually unpersoned from Fanfiction.net, but can be found here.
And good ol' 1d4chan has a massive compendium of variants. This thing
No, John. You are the Tropes:
- Action Hero: John Stalvern. He solves most of his problems by shooting them with his plasma gun.
- Aerith and Bob: Within one person's name, no less. A cursory Google search suggests the name "Stalvern" may not have existed until the writing of this story.
- And Then John Was a Zombie: The Trope Namer.
- Anti-Climax: Just as John is about to take the fight to the demons that plagued his memories for so long, the ceiling falls and traps everyone.
- Calling Your Attacks: The Cyberdemon says "I will shoot at him" before he fires the rocket missiles.
- Cassandra Truth: Cernel [sic] Joson doesn't listen to John's warnings about the monsters.
- Cruel Twist Ending: John fought the demons and then was a zombie.
- Death by Transceiver: Strangely inverted and parodied as John is somehow turned into a zombie by talking into his radio.
- Department of Redundancy Department:
- Rocket missiles.
- "[...] and now it was too late. Far too late for now, anyway."
- Determinator: John Stalvern. He only thinks about stopping the demonic invasion, even as he's being crushed to death.
- Diabolus ex Machina: The ceiling falling during the fight with the Cyberdemon.
- Downer Ending: John is a zombie. Or, at least, he becomes one. We think.
- Dramatic Reading: A major target for them.
- Dramatic Thunder: "The lights above him blinked and sparked out of the air."
- Eager Rookie: Protagonist John Stalvern is really excited to join the marines, despite his father attempting to dissuade him by saying he would be killed by demons.
- Falling Chandelier of Doom: The ceiling falls and makes everyone unable to kill.
- Flashback: John flashes back to a moment from his childhood when he watched spaceships with his father, who didn't approve of his desire to be on them, lest he 'BE KILL BY DEMONS'
- Gainax Ending: Why does the ceiling collapse? Why does John become a zombie? Who's talking on the radio at the end? In any case, the ending could be taken a couple different ways. If we go by the source material, Doom, we can guess the demons killed John and possessed him. The ending also seems to imply that John was always a zombie, and his attacks on the "demons" was him attacking humans. Which, insanely, actually adds some unexpected depth to the Doom games if this holds true for all of the zombies. In fact, it is possible this plot was stolen from a 90s Outer Limits episode which ended almost the exact same way.
- The Hero Dies: John. Or at least he is then a zombie.
- He Who Fights Monsters: At the end, John, who was killing the demons, became the demons. And then a zombie.
- The Killer in Me: John is the demons. And then a zombie.
- Masquerade: John used to believe in demons when he was young, but then he stopped when he got oldered. However, demons are real in the story.
- Minimalist Cast: A whopping four characters: John, Joson, John's father, and the cyberdemon.
- Oh, Crap!: "HE GOING TO KILL US", as eloquently stated by the demons upon seeing John.
- Plasma Cannon: The 'palsma rifle' that John uses to blow up the wall, and later he plasmaes at the cyberdemon with it.
- Rocks Fall, Everyone Dies: Quite literally. The battle between John and the Cyberdemon abruptly comes to a halt when the ceiling falls on them for no apparent reason.
- Rouge Angles of Satin: It could be quite possible that palsma is a unique variant of plasma.
- Space Marine: John, for fourteen years.
- Stealth Parody: At the time of release, some were skeptical that a person could genuinely have such poor English and writing skills. However, writing this bad for 7 years seems suspicious. Those who were suspicious were right, as years later, the mastermind behind Peter Chimera "Heisanevilgenius" admitted that he felt like creating fanfics that parody fics with bad English.
- There Was a Door: Parodied in the animated adaptation where John blasts through a wall and then uses a door a few feet away.
- Tomato in the Mirror: One possible interpretation of the ending is that John was always a zombie and didn't realize it until now.
- Through the Eyes of Madness: Another similar explanation of the infamous plot twist: the "demons" are actually regular humans who John was hallucinating as demons.
- Troll Fic: It came out later that the author intended for this and his other works to be parodies.
- Troperiffic: True, it doesn't contain a huge number of tropes, but look at it in a "trope density" sense. The story has 211 words. There are 33 tropes listed on this page (including this one). That's more than one trope every seven words. Furthermore, this trope page is currently longer than the work itself.
- Unsound Effect: The story rather infamously uses "plasma'ed at" as a verb.
- The Voice: Cernel Joson, who gives John his orders.
- Wham Line: "No, John. You are the demons."
And then John was a Troper.
