Which character serves as a foil to Tybalt?

Benvolio, the consummate peacemaker, is the foil to hot-tempered Tybalt in Shakespeare's Romeo and Juliet. The first scene of the play clearly establishes Tybalt as dangerously aggressive when he becomes enraged by Benvolio's attempts to stop a fight. In his frustration, Tybalt turns his sword on Benvolio.

Tybalt is the main antagonist in Romeo and Juliet. By staging a confrontation with the pacifistic Benvoilio, Shakespeare shows Tybalt's desire to fight even those who would prefer to walk away. This desire for violence and contempt for those who do not wish a confrontation foreshadows the tragic results of Tybalt's reaction when Romeo later refuses to fight him.
