Tybalt shares the same name as the character Tibert/Tybalt the "Prince of Cats" in Reynard the Fox, a point of both mockery and compliment to him in the play. Mercutio repeatedly calls Tybalt "Prince of Cats" referring to Tybalt's expertise with the sword, as he is agile and fast, but also it is an insult.
Tybalt is first seen coming to the aid of his servants who are being attacked by the servants of the Montagues. He is also present at Capulet's feast in act one, scene five, and is the first to recognize Romeo. His last appearance is in act 3 scene 1 where Mecurtio insults Tybalt and ends up fighting with him. Tybalt kills Mecurtio but due to Mecurtio's death Romeo rages and kills Tybalt, This resulted in Romeo's banishment. He is Capulet's nephew and Juliet's cousin. He is close to the Lady Capulet.
