assailer
An assailant is a person who attacks or assaults another person. The term is often used in legal contexts to describe someone who has committed an assault or battery. An assailant's actions can range from verbal threats to physical violence. The severity of the assault can influence the legal charges brought against the assailant. The intent of the assailant is often a key factor in determining culpability and the appropriate legal penalties. Self-defense can be a legal justification for responding to an assailant's actions.
