Bugbear

[Sarah]

Something frightful, as a specter; anything imaginary that
causes needless fright; something used to excite needless fear; also,
something really dangerous, used to frighten children, etc.

[Jason Yan]

Bugbears are the largest of the goblinoids. these huge creatures tower over the [battlefield], srtiking terror into all who see them. [like many] large creatures bugbears are both helped and hindered by their great size. their tremendous strength makes them [wrecking] machines in combat, but drops their armor class making them more vulnerable.

[Zipporah Schumaker]

A cause of obsessive fear, anxiety, or irritation.
