Future Trunks (未来のトランクス, Mirai no Torankusu; lit. "Trunks of the Future") is the Saiyan and Human hybrid son of Vegeta and Bulma from the 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 the exact same lives as their counterparts until the point at which the two timelines diverge, three years before the androids). "Mirai" is the Japanese Kanji name for 'future'.
This is the first Trunks that the readers and/or viewers ever see in the manga and anime. Trained by the alternate timeline's Gohan, Future Trunks travels through time to seek help from Goku to prevent the Androids from ravaging the world, like they did in his dark future. Future Trunks is a loyal and uncompromising warrior, and can be slightly cocky at times. He inherited his mentor's do-or-die attitude, as well as his father's brash confidence (though he displayed less of it at different times; it was most on display in his fight against Frieza). He wields a sword of unknown origin and wears a Capsule Corporation jacket.
