Future Trunks

Future Trunks (未来のトランクス), referred to in the series simply as Trunks, is the Saiyan and Human hybrid son of Vegeta and Bulma from the alternate future. By the time Present Trunks was born, the timeline had been altered by Future Trunks' and Cell's trips to the past. Therefore, the two Trunks had completely different lives (as opposed to those who lived before the Time Machines arrived, they lived exactly the same lives as their counterparts until the point at which the two timelines diverge: three years before the androids arrived).

Well-mannered, serious and very cautious, Future Trunks hails from an alternate timeline in which Android 17 and Android 18 murdered the Z Fighters and proceeded to create apocalyptic hell on Earth.[4] Future Trunks is trained by Future Gohan as a teenager, and becomes a gifted fighter, swordsman and a Super Saiyan; traits that aid him greatly in the battle against the Androids after traveling back in time in order to save his own future.[5]
