"Quick to the Trigger" is a {{Crossover}} fanfic between [[Franchise/PowerRangers Power Rangers]] and [[Franchise/KamenRider Kamen Rider]]. It starts off the night before the opening of a big exhibit in the Los Angeles Musem of History and a strange benefactor has asked the [[Series/PowerRangersTimeForce Silver City Guardians]] to guard it. The find revolves around the discovery of a humongous Serpent skeleton found in the Sahara desert. On the same day as the exhibit's grand opening, there's a book signing by the famous paleontologist [[Series/PowerRangersDinoThunder Dr. Thomas "Tommy" Oliver]] being held in [[Series/KamenRiderDragonKnight Grace's Books]]. Unfortunately, when Tommy Oliver is about to make his speech, he collapses and a strange boy takes Dr. Oliver's body away. Not long after, a [[Series/KamenRiderDenO train shaped like a giant bull]] arrives with warnings of a great danger up ahead.

It turns out that in the very distant future, a boy known as [[Series/KamenRiderFourze Gentaro Kisaragi]] somehow awakens from his slumber and plunges the Earth into chaos. Dr. Oliver is related to this madness, alongside the giant twin-headed snake flying across the city and the events that would cause Earth to become a living hell.

The story is being written by Green Phantom Queen, known for her other well-known work, ''FanFic/{{Horseshoes and Hand Grenades}}''. The story fits within Horseshoe's timeline, but aside from references and a few characters mentioned, the story can be read as a separate piece of work, although the multiple references only make sense if one actually has read the fics involved.

!!Quick to the Trigger provides examples of:
* AlliterativeTitle: Dr. Oliver's book is known as ''Serpentine Stories: The Myths of the Sacred Serpents''.
* BadFuture: What happened when Gentaro wakes up later on.
* CameBackWrong: [[spoiler:[[Series/PowerRangersZeo David Trueheart]]]]
* ContinuityNod: Maya reads one of [=SplitxEnd=]'s messages regarding Gentaro's death.
* {{Crossover}}: On the Power Rangers side we have [[Series/PowerRangersTimeForce Time Force]] and [[Series/PowerRangersDinoThunder Dino Thunder]] representatives. For the Kamen Riders we have [[Series/KamenRiderDragonKnight Dragon Knight]] and [[Series/KamenRiderDenO Den-O]], with more to come from the looks of it.
* DeadpanSnarker: Tommy.
* EarlyBirdCameo[=/=]LateArrivalSpoiler: Varies. It's an EarlyBirdCameo due to many characters coming from the future, but a LateArrivalSpoiler because of how the stories were published. For example: [[spoiler: Hayato is revealed to be a future Shun Daimonji resurrected by Vasuki, but Shun himself doesn't become a Serpent-bearer until the 13th chapter of ''Horseshoes and Hand-Grenades''. ''Quick to the Trigger'' starts on a Tuesday--Shun dies three days later.]]
* {{Epigraph}}: Just like in Horseshoes.
* {{Foreshadowing}}: The end of the first chapter has the voice in the stranger's head mentioning that "We don't want this little ''trip'' to end in disaster." [[spoiler: The next chapter reveals that the stranger is [[Series/PowerRangersTimeForce Trip]]]].
* HeroesOfAnotherStory: Back in ''Horseshoes and Hand-Grenades'', Owner mentioned how Ryotaro, Kotaro and Yuto were off fixing some stuff in the past. This is what they've been doing.
* HeroicBystander: Maya, throwing a book at the "strange person" (later revealed as [[spoiler: Trip]]) from getting away.
* IdiosyncraticEpisodeNaming: Each chapter is called 'Trigger' and each chapter name is a phrase or song starting with the last word(s) from the previous chapter, similar to ''Horseshoes and Hand-Grenades'' and ''A Month of Sundays''.
* ItsALongStory: The dialogue in the second chapter.
-->'''Ethan:''' Ventara? What type of strange world is that?
-->'''Kit:''' Long, long story.
** Teddy also gets into this during the WriteBackToTheFuture situation.
* MythologyGag:
** Tommy still has his old [[Series/PowerRangersZeo arrowhead pendant]]. Ethan also makes references to Tommy's archives on former Power Ranger teams upon meeting Wes and Eric.
** Kotaro is depicted with blond hair, just like in ''Let's Go Kamen Riders''.
* {{Necromancer}}: Hayato when he revived [[spoiler: David Truehart]], although he states that it wasn't easy to do.
* NoodleIncident: Hayato's necromancy was apparently so horrible that Yuto almost swore to eat nothing but shitake mushrooms for the rest of his life.
* OneSteveLimit: Averted with Trent Fernandez-Mercer (Dino Thunder) and Trent Mosley (Dragon Knight).
* SarcasmBlind: [[spoiler: Vasuki]] upon reacting to Tommy's comment.
-->'''Tommy:''' ''(Upon learning that his death had been delayed)'' Oh, I'm so flattered.
-->'''[[spoiler:Vasuki]]:''' You should be. [[spoiler: You would've been the main general of the Armed Forces of Ouroboros.]]
* ShoutOut: The beginning of the third chapter has Kira singing [[Series/SoWeird "In The Darkness"]] and she and Maya brings up Fiona Philip's old paranormal website.
* ThatManIsDead: Hayato, who insist that he gave up his original name [[spoiler: Shun Daimonji]] a long time ago.
* ThrowTheBookAtThem: Maya does this to the stranger in the second chapter.
* WriteBackToTheFuture: A photo of a snake bracelet has the word [[spoiler: Trueheart]] written on it which is related to a few time-travelers working on ensuring that events in the present are being played out.
