Fearsome Foot

A scary character is approaching, and the camera focuses on his/her foot crushing something, or just emphasizes the is frightfulness with a closeup of the characters feet/boots, which may be adorned with Spikes of Doom or the like. Very common for an Attack of the 50 Foot Whatever.

Subtrope of Foot Focus, but in a scary or Badass way instead of a sexy way. Differs from Feet First Introduction in that it isn't necessarily the first appearance of the character.
