Trunks

Trunks is the son of vegeta and bulma. Trunks is a half saiya-jin half human. Like gohan trunks has 2 life lines. One when the androids killed all the z fighters except trunks and gohan, and nobody could kill them. The second when trunks grew up with goten and all the z fighters. Trunks like all the z fighters is a very powerful warrior. Trunks is a serious fighter just like vegeta. He also made up just about all his own attackes. At times trunks can be a funny kid. The sword that trunks uses in the future timeline was given to him by tapion. It is the sword that he uses to kill furiza. If trunks had not gone back to the future to warn everybody about the androids all the z fighters would be dead, there would be no cell, or buu. Without him nothing would exist. After returning from the past to his time line he destroyes the androids that had killed so many humans, then after returning the second time he killed cell.
