Trunks

Trunks (トランクス, Torankusu) is the Saiyan/Human hybrid son of Vegeta and Bulma from an alternate timeline. He's a playable character in Dragon Ball FighterZ, fighting in his Super Saiyan form.

Background
In the future, a pair of androids created by Dr. Gero ravaged the Earth. Trunks, the son of Vegeta and Bulma, went back in time in the hopes of changing history so that the devastation he grew up with would be averted. Even though he would not be able to change the history he came from, he would help Goku and his allies fight against Cell to protect the history of this new timeline, then return to his own time to save the Earth from the androids of his own timeline, restoring peace to the world until the arrival of Goku Black...
