Trunks  Future Trunks: He hits the scene at  age 17 by traveling back in time. He does so with a bang by  destroying both Freezer and his father. But he came with a grim tale  of the future, a future where all the Dragon Ball Warriors were  killed except for himself and in a future dominated by two powerful  cyborgs #17 and #18. Trunks traveled back in time hoping to  change the future by changing the fate of Son Goku. In his future,  Son Goku died of a rare heart disease. He believed that Goku was  pivitol to the events of the future, so he brought the medicine  necessar to save his life. Even though his future could not be  changed, he hoped that the "present" will not turn out like his  future. In the end, he got more than what he had bargined  for. Not only was he able to completely change the events, but he  also, under the guidance of Goku and Vegeta, he became more poweful  than he could imagine, enabling him to put right, his  future. Chibi Trunks: Like Goten, he was able to  achieve Super Saiyajin at a very young age. Due to the lack of  available warriors, he performed a fusion with Goten into Gotenks to  battle Dämon Boo.
