In a confrontation between two parties, where one is being aggressive towards another (either by attacking them or by simply posturing and frightening the other), one side could be referred to as the "aggressor", but what could the other be called? I'm looking for a one-word description if possible.
"Victim" sounds too strong a word for simply being intimidated and backing away from the confrontation, and the only other term I can come up with, "target" seems too vague.
Example: The aggressor [attacked / intimidated] the ______. Then the _____ ran away.
