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. Therefore, the two Trunks had completely different lives (as opposed to those who lived before the Time Machines arrived, who lived exactly the same lives as their counterparts until the point at which the two timelines diverge, three years before the androids arrived).

More than 10 years later, Future Trunks would return in Dragon Ball Super, this time fighting against a mysterious entity referred to as Goku Black (and later his counterpart) wreaking havoc in the future. In the end, Trunks (with the help of Goku and Vegeta) neutralizes the threat, though unfortunately, Zamasu not only survives the ordeal, but he becomes an even bigger threat, to the point that Future Zeno was needed to erase him. Trunks himself is one of the three survivors and is currently living in another future timeline where another Future Trunks exists - created in the anime by Whis warning Future Beerus ahead of time to eliminate the soon-to-be rogue Supreme Kai, while in the manga Trunks and Mai travel to their timeline's past and prevent Future Shin's death with the blessing of Beerus as it will save his counterpart, thus eliminating the possibility of the Project Zero Mortals.
