Trunks, (the present form) is the son of Vegeta and Bulma. He is an incredibly strong boy, however he will never posses the strength that his future counterpart did. At the age of eight, Trunks was able to go Super Saiyan. He won the title of Junior World Champion after a long battle with his best friend Goten at the World Martial Arts Tournament. After this, he fuses with Goten to form Gotenks, and a very powerful fusion this is. In GT, Trunks travels the universe in search of the Black Star Dragonballs with Pan and "Chibi Goku". At this point he is about eighteen.
