!!Tropes associated with Studio Trigger:
* AnimationBump:
** ''Kill la Kill'' has several higher quality moments in spite of its many OffModel and LimitedAnimation moments.
** ''Kiznaiver'' can be considered this for the studio as a whole.
* ArmsAndArmorThemeNaming: The Trigger Girls are all named after gun parts: the orange-haired one is named "Trigger", the blue-haired one "Muzzle", and the blonde one "Spring".
* AuthorAppeal: LimitedAnimation and OffModel are always featured in their series.
* {{Fanservice}}: ''Anime/KillLaKill'' is this to a T.
* LimitedAnimation:
** Invoked as all of their series exhibit this, with ''LightNovel/NinjaSlayer'', ''WebAnimation/InfernoCop'' and ''Anime/SpacePatrolLuluco'' being the most blatant cases. [[TropesAreNotBad It's not a bad thing though]].
** ''Kiznaiver'' [[AwesomeArt beautifully]] averts this.
* {{Mascot}}: [[https://www.youtube.com/watch?v=YZ2G5iXCVMw The Trigger Girls]]. While the prospect of an anime starring them started out as an AprilFoolsDay joke, it's eventually revealed that [[spoiler:the middle one, AKA Miss Trigger, is actually [[Anime/SpacePatrolLuluco Luluco]]]].
* {{Motif}}: a large, 4-pointed star is seen regularly in Trigger animations. Most prominently in ''KillLaKill'', ''LittleWitchAcademia'', and ''SpacePatrolLuluco''
* OffModel: Invoked as all of their series feature this. [[TropesAreNotBad It's not a bad thing though]].
* TheVerse: [[spoiler:''Anime/SpacePatrolLuluco'' ends up sharing one with at least four other Trigger works and is the origin story of the studio's mascot]]. [[spoiler:''Anime/PantyAndStockingWithGarterbelt'', despite not being a Trigger property, [[http://imgur.com/a/rFpaa is also part of this universe]].]]
