The TVTropes Trope Finder is where you can come to ask questions like "Do we have this one?" and "What's the trope about...?" Trying to rediscover a long lost show or other medium but need a little help? Head to Media Finder and try your luck there. Want to propose a new trope? You should be over at the Trope Launch Pad.
Find a Trope:
openLoving the Betrayer Anime
This trope might usually be associated with love stories but is there an existing trope for when a character reveals that they were betraying another character but the said character then reveals that they knew all along and still decided to love them?
opensatisfied slump of defeat Anime
Often used in a comedic manner—character is sitting under a spotlight without color and smiling with a satisfied/contempt look on their face while their eyes are closed. Similar to corner of woe. IIRC Captain Obi from Fire Force and Dino from Blend S did this in an episode of their respective series.
openAPP The same but shorter Anime
Is there a trope for when a cartoon character's child design (or toddler/younger child if they are still a child) is basically the same design or their older self but shorter? It can also be like they have the same hairstyle and clothing but with minimal differences like a tooth missing??

A monster or whatever mimic speech and speaks broken english/whichever language to communicate? I remember seeing it in an anime late at night.
