Bully; scare
I believe the answer is:
intimidate
This clue is a double definition.
'bully' is the first definition.
(I've seen this in another clue)
'scare' is the second definition.
(intimidate can mean to scare)
(Other definitions for intimidate that I've seen before include "Scare" , "Strike fear into" , "Threaten" , "Cow" , "Frighten" .)
