Before you read my story I just want you to know that I've only seen Dragonball Z up to the end of the Freeza saga so this story takes place right after they wished back Krillin, it is also assuming that Goku came back to earth when Krillin did.
Gohan blinked twice before he opened his eyes for the first time after the explosion. His vision was blurred and it took him a minute to focus on the two motionless bodies to his right which could only be described as thrashed. These were the bodies of Krillin and Piccolo. At the sight of this only two questions crossed his mind, one how had he alone survived and two where was his dad, where was Goku? Thats when he saw it, someone else had survived and he was at that very moment fighting Sazar, A warrior from the distant planet of Volderon. Sazar had had shown up early that morning "Its the Saiyans I'm after" he had said" It was they who destroyed my planet, and it was they who destroyed my kind"
Vegeta, as always much to confident about his fighting abilities was the first to approach this powerful new enemy. " I am Vegeta Prince of all Saiyans" he had proclaimed with a great deal of pride. This had been a mistake, for the power level of this new fighter was even higher then that of there pervious adversary Freeza. The battle between Vegeta and Sazar lasted little more then an hour before Vegeta was sent to another dimension.
They had all contributed greatly in fighting an enemy who didn't even flinch at the use of there most powerful attacks, eventually sacrificing there lives in a battle they couldn't possibly win. Now only Gohan and who he assumed was Goku were all that stood between peace and total oblivion.
But could that really be Gohans dad that was fighting right now, could that really be Goku. Of coarse it was Goku, who else could it be the power level was through the roof, to high to be anyone else, and besides everyone else was dead. But they were moving at such a great speed that Gohan couldn't even begin to trace their movements, it was the high level of there power that gave away their identities almost instantly.
"Kamehameha" Gohan heard his dad who was looking pretty beat up, say as the powerful beam of energy flowed from his fingers like water from a hose. Sazar remained where he had been floating without a scratch, then suddenly sent his own attack Gokus way. He was tossed to the ground rag doll forming a crater the size of a small lake. Gohan looked on in horror as he realized that his dad had already gone SSj. Sazar followed by hitting Goku with all the energy he could muster without enervating himself any further. Goku didn't move.
"Finally I have rid the universe of your kind, and now I will relive it of this worthless planet as well" Sazar bellowed at Gokus limp body."Not quit Sazar" Gohan said as he stood starring at the warrior. "You expect me to be defeated by a child when I was able to beat that poor excuse for a saiyan, who was supposedly the strongest man in the universe" Sazar replied with a smug little laugh.
"That poor excuse for a Saiyan as you call him is my dad" Gohan shouted with extreme anger. His hands closed into fists and he could feel himself becoming stronger. His power level skyrocketed and he was engulfed by pure power, then suddenly he knew. Now his hair was that same distinct shade of gold as his dads, he had become a SSj. " Now your gonna pay for what you did to my friends, Kamehameha" He exclaimed flying toward Sazar.
The blast of energy Gohan exerted sent Sazar fling to the ground forming another crater right next to Goku's. Sazar got up and flew back to where he was before, Gohan could tell that he was hurt." Do you really think I'm going to let myself be beaten by a Saiyan and a child at that" Sazar said as he released a blue beam of energy at Gohan but he didn't waver." You really don't have much of a choice do you, except that my dad would want me to give you the leave while you still can" Gohan said in a very serious voice.
" This isn't over until one of us is in another dimension" Sazar shouted once again attempting to blast Gohan but failing once again. "Fine then you had your chance" Gohan exclaimed using all of hi strength to knock Sazar back into the crater.He says"Kamehameha" and hits him with about everything he's got until he is sure Sazar is dead. Gohan ( no longer a SSj) looks around at the motionless bodies of his friends," I guess I should start looking for the Dragonballs".
The end
