If fans saw Gokus son grow up to become a strong Sayian, its only fair that Vegetas son, Trunks, also gets some spotlight. Born in the Android saga, there wasnt enough time for him to grow up into a man, even till the end of Dragon Ball Super. So in a stroke of mastery, Akira Toriyama brought a grown-up Trunks from the future, merging time travel with the concept of various timelines, while introducing fans to Future Trunks, who quickly became a fan favorite after he made short work of Mecha-Frieza.
