Beware the Quiet Ones or Beware the Nice Ones may be what you're looking for.

Possibly Rant Inducing Slight if what sets the character off is comparatively minor.

Related to Berserk Button, perhaps? If the character is calm and collected but has a well-known trigger that sets them off?

Rage Breaking Point if something pushes a character beyond their self-control
Is there name for that trope where a calm, collected or serious character becomes chaotic or goes totally crazy for an episode?
