!!Tropes associated with Studio Trigger:
* AnimationBump: ''Kill la Kill'' has several higher quality moments in spite of its many OffModel and LimitedAnimation moments.
* AscendedFanboy: Given that the series is founded by ex-Gainax members, this is to be expected.
* FanService: ''Anime/KillLaKill'' is this to a T.
* LimitedAnimation: All of their series exhibit this, with ''LightNovel/NinjaSlayer'' and ''Anime/InfernoCop'' being the most blatant cases.
* OffModel: All of their series suffer from this.
