Trunks
"I will not let this happen again!"
I'm just talking about the trunks that came from the future. He came from the future because his mother(Bulma) told him to help Goku stay alive, knowing that it would do nothing to help his time. He saved Goku and stayed for awhile to help stop Cell. During that time he bonded with the father(Vegeta) that he never had. After Gohan defeated Cell, Trunks was wished back(because he was killed by Cell), he returned to his time, killed both the androids and Cell in the same episode. It was a sight to see. I suggest you watch that episode, it was the last episode they showed of Dragon Ball Z on Cartoon Network. For now.
