After the conclusion of the Cell games Gohan felt alone in the world so using the dragon balls he wished back planet Vegi-sai. As well as every sayian on or off the planet when Friza destroyed it. He then stole a ship and headed to new Namek and summoned there dragon with it he found his entire sayian family he also wished his uncle back on the condition that he was no longer evil.
When the sayian race returned they found out about Friza and cell as well as all the other adventures the z fighters had bin on since the destruction of the planet. They decided that they would no longer conquer planets they would instead seek out and destroy only those still aliened with the dead tyrant.
When Gohan arrived of Vegi-sai he was welcomed as a brother whilst there he met his grandfather Bardock his mate Frasha and his cousin Torma. When they met they became close he was orphaned because his farther died two years before Friza came and his mother died in labour.
After a few days on the home planet he gathered his sayian family and headed off back to earth where they met the unstoppable force known as Chichi. After a getting to know them she accepted them into her family even Raditz who asked for forgiveness for what he did to Gohan. Gohan being the kind of guy he is accepted his apology.
For a while they settled on earth but then they all went to Vegi-sai with Vegita who upgraded the house of Bardock to an elite standing. Gohan decided to join the sayian military. He made sure to keep up with his studies and they even got Torma in on it too much to his annoyance. After a few years Torma was adopted by Chichi and he and Gohan officially became brothers.
Gohan now a general in the elite guard some times participates in missions but only ever high level ones. His team consists of him and Torma they always wore black and dark gray armour and became known as the Black opp's Elites. They go to planets with insanely powerful enemies and conquer it. Also they only took the most ridiculously hard missions that know one would touch. The two looked like twins except in size Troma was a 6ft 9 wall of muscle and Gohan was only about 6ft 2 they became the first super elites witch placed them just below the royal family in there standing. After two years and several hundred missions Torma became an ssj1 and has been able to push the power to ascended
A few month after the cell games Chichi gave berth to twins Goten and Gogan who were raised along side Trunks the three young boys becoming as close as brothers. Goten looking a spitting image of Goku as Gogan looked similar to Goku but had long hair.
Torma and Gohan are not only brothers but rivals Torma has reached the level of ssj2 and Gohan ssj3 but also they are keeping that secret from each other in order to surprise the other.
In-between missions they enter the galaxy martial arts competition and have one at least 4 times the final round usually consisting on Torma vs. Gohan. The prise money making them ridiculously rich. Between them they have they enough to by a planet each and the entire solar system as well.
