 
Future Trunks is a Saiyan-Earthling hybrid and the son of Vegeta and Bulma, both from an alternate future. By the time Present Trunks was born, the timeline had been drastically altered by Future Trunks' and Cell's trips to the past. Trunks is trained by Future Gohan as a teenager and becomes a gifted fighter, swordsman and a Super Saiyan, which are traits that aid him greatly in the battle against the Androids after traveling back in time in order to save his own future.
