Tybalt is a character in "Romeo and Juliet" by William Shakespeare. After Romeo and Juliet are married Tybalt becomes related to Romeo because Tybalt is the nephew of Lady Capulet who is Juliet's cousin.
He says that Tybalt came after Romeo but Romeo "spoke him fair", so he then went after Mercutio, and killed him when Romeo was trying to restrain him. He says Tybalt then fled, "but by and by comes back to Romeo" whereupon Romeo killed him, Benvolio being unable to prevent it. This is mostly true, although he withholds the fact that Mercutio went out of his way to start a fight with Tybalt, who had no interest in fighting him. What Tybalt would have done to Romeo had Mercutio not been there is a director's call. The play is clear that in fact Tybalt did seek Romeo out after Mercutio's death, so Romeo was acting in self-defence in fighting him. Tybalt re-enters and Benvolio says "Here comes the furious Tybalt back again." In most movie versions, it is Romeo who chases after Tybalt, which would make this part of Benvolio's account of the fight inaccurate also.
Mercutio accepts Tybalt's challenge on Romeo's behalf. But it may be debated whether Tybalt would have murdered Romeo had Mercutio not intervened--probably not. The only point where Tybalt was actually on the point of killing Romeo was when Romeo attacked him, and Romeo was the one who prevented Tybalt from killing him.
Tybalt is the main antagonist in the famous play, "Romeo and Juliet." In the play, Tybalt kills Romeo's close friend Mercurtio. Tybalt is later killed by Romeo in retaliation.
