But if Gohan wasn't around to teach him how to fight, Trunks would have died a long time ago & wouldn't have gone back in time
Trunks did good on his own for well over a decade. Gohan's training didn't even get Trunks anywhere in the future in the long run. He got beat when he encountered the androids after Gohan was killed. Which of the two survived their whoopings?. Those genes
the inherited resilience
. Whose training actually mattered in the long run?
Vegetas
He pushed his boy and unlocked his potential which led to his son saving his future timeline. Meanwhile Kakarots son's power drastically deceased and he started playing dress up, that aint no saiyan
Trunks saved the earth when Kakarot's lazy ass turned up late to stop Frieza and King Cold's army who were on the verge of blowing it up. Goku didn't do shyt during the Android/Cell saga. Vegeta, Trunks and Piccolo were the ones who held it down whilst he was shivering and quivering in bed. He didn't win a single fight in that saga. Bulma was also the one who found out about Cell and the time machine, pops also built the remote that would have shut the Androids down, that family contribution and effort
.
