Stop, drop and roll dude.
Trunks is the son of Vegeta and Bulma.
In order to change his shattered future, a world where most of the Z-fighters have been killed by the merciless androids, he travels to the past in a time machine.
In his own time, Gohan, the last surviving Z-fighter, had been Trunks' friend and mentor. Trunks looks forward to seeing Gohan again, and to meeting his father, Vegeta, for the first time.
His final objective in his mission to the past is to deliver a cure for the fatal heart virus that, in Trunks' time, took Goku's life before the androids even arrived.
He uses Goth Juice I can tell.
