Trunks's Bio

Trunks is Vegita's son. In his future, all of the Z fighters were killed by the Artificial Humans, except for Goku, who died of heart disease. Trunks travels 20 years back in time to give medicine to Goku so he can survive this disease and defeat the Artificial Humans. Trunks' returning in time alters the past in other ways which can be seen later.

After giving the medicine to Goku, Trunks goes back to his own time, but returns again three years later to help the Z fighters battle the Artificial humans. During this time, he becomes extremely powerful and surpasses every other one of the Z fighters except for Gohan and (maybe)Goku. 1
