Types of Jaw Drops
Where a hero just drops his jaw in pure shock. While this often seen for comical purpose, this not always the case, as sometimes led to breakdown or other form of stress/dissappointment, especially in horror fictions. This can be triggered by following situations that extremely shocked them such as:
 * A character whom suddenly making an unexpected decisions, which often not something that they desire.
 * Sudden misfortunes which came to them almost without warning, which can be in form of enemy's ambushes, unexpected death, etc. (Eugene H. Krabs had his millionth dollar suddenly chomped away by giant clam where it supposedly safe or Armin was horrified by Eren's sacrifice for example).
 * Having oneself facing something that not they expected like an extremely beautiful/handsome figure, something that very big, etc.

Examples
