Son of Vegeta and Bulma, Trunks is only an infant when he first appears in DBZ during the Android Saga. He has purple hair like his grandfather Dr. Briefs, but his facial features, stance and strong Saiyan pride clearly show that he is a descendant of the Saiyan royal line. He has a sister named Bulla who is about 12 years younger than he is. His role becomes much larger by the Buu Saga, at which point Trunks is 8 years old and fantastically strong for his age. He goes Super Saiyan while training with Vegeta in the gravity room, an event that comes as a shock to all considering his young age. Filled with pride, Chibi Trunks is adventurous and constantly looks for stronger opponents to challenge, much like his father. During the final episodes of DBZ, Trunks, who is now 18, appears to be developing the same personality as Future Trunks. He can be seen as adult Trunks throughout GT as well. Trunks is born in the year 766 AD, and is 29 years old by the end of GT.
