Answer
Tybalt, the fiery cousin of Juliet, serves as a catalyst for the tragic events in Romeo & Juliet (2013). His impulsive and aggressive nature fuels the already tense feud between the Montagues and Capulets. Tybalt's burning desire for revenge against Romeo, who had crashed the Capulet ball, ultimately leads to the deaths of Mercutio and Romeo, setting the stage for the play's tragic conclusion.
