Chekhovs Skill: Fan Fiction

  • In Kyon Big Damn Hero Mikuru asked Yuki to teach her to be a paramedic in order to build confidence and have an helpful skill while Kyon and Kanae are training. This becomes useful later when Kyon got hurt after a battle and Yuki can't heal him.
  • This is more like Chekhov's Habit, but there's a Running Gag in Hunting The Unicorn of David writing down everything relevant to the Warblers (and especially Blaine). It proves useful when he has hard evidence that Blaine has a stalker.
  • In the Transformers fanfic series Black Crayons, Ironhide begins teaching Annabelle how to speak Cybertronian. First, it is a cute way to learn about the Twins' pranking plans. Later, it becomes a life-saving skill when she overhears a key piece of information from Starscream.
  • Jack's ability to memorize fingerprints on things to distinguish them from similar things helps him put out a fire at Dr. Brainstorm's lab in Calvin and Hobbes: The Series.
  • In Ace Combat: The Equestrian War, some tactics and maneuvers shown by Firefly help her wingmares (especially Rainbow Dash) in future battles.
  • In the second chapter of A Growing Affection Hinata suggests Naruto work on chakra control by trying to create a tiny Rasengan on each finger tip. This becomes the Five-Points Rasengan jutsu, and shows up multiple times in the story, including the final battle.
  • Legacy Of The Rasengan: Naruto has Kaze Kiwa no Jutsu. In this fic it's one of Naruto's signature moves and sees a lot of use. It ends up inspiring Naruto to create the Rasengan since the mechanics of both are similar (no hand signs, spinning chakra, very good chakra control). Also helps Naruto in his fight with Neji since it made it easier for him to concentrate his chakra enough to mimic Neji's fighting style and rip through his Rotation.
  • Regeneration in Children of Time: Kit Bennett reveals herself as a Time Lord, and the Daleks torture her to study a Time Lord's use of regenerative energy. At the climax, Kit uses a burst of that energy to knock out the Daleks' computers, destroying Dalek Caan in the process. Then in the season finale, baby Katherine, who will grow up to be Kit, heals her dying father and half-dead godfather.
  • In Break My Fall, Red spends his lunches helping out at the nurse's office. This later becomes important when he has to rush to the nurse's office after school hours to get supplies to treat Green's self-harm wounds.
  • Subverted in The End of Ends. You'd think Beast Boy's Magic Voices might be the reason for why he sounds so different as Count Logan, but it's revealed that the mask simply disguised his voice.
  • In Despair's Last Resort, Naomi is established as being the Super High School Level Translator, who knows ten languages. As she's dying, she uses her blood to leave a dying message. But in order to hide it from the killer, she leaves it in French. This allows the one living student who knows French to pick out who the culprit is.
    • Takara's experience as a journalist helps her out in the investigations.
  • Kitsune no Ken: Fist of the Fox. During her fight with Kin in Chapter 16, Ino demonstrates that she's got an extremely painful Groin Attack that she learned in order to deal with any perverted men who'd try to hit on her while shopping at her father's store; said attack consists of grabbing the victim's privates and twisting. That tactic proves extremely useful 68 chapters later to deter Aoi's Attempted Rape.
  • FateBlack Reflection. Rider dreams about Ichigo's fight with Kenpachi in Soul Society through the Command Seal link. The next night, Ichigo displays the ability to handle Berserker easily, to the wonderment of everyone else there. Rider eventually recalls the dream and realizes that the reason Ichigo can fight Berserker so well is because he has experience fighting opponents with overwhelming power and no strategy.
  • The Fifth Act. Genesis always tries to cast status effects on Cloud, only for them to never work. Once Cloud gets possessed by Jenova, Genesis's reflexive casting stopped Cloud without them having to kill him.
  • In Katawa Shoujo post-Hanako Good End fanfic Fan Fic/Sisterhood, Hanako attends a first-aid course, the intention being she would be able to put it into practice and use these skills to keep calm in the event Hisao was to have another heart attack, unlike the previous time in which she had a severe panic attack. Instead, she ends up using her skills to save Lilly's father's life after he collapses from a heart attack.
