Chapter 1- A New Adventure
"Hurry up Trunks or I'll leave you behind," yelled Vegeta. "I'm coming father," Trunks replied. It has been over three hundred years since Goku left with Shenron and the Dragonballs to train in the afterlife, and Vegeta and Trunks are the only two saiyans left alive. Since Vegeta and Trunks were the only Saiyans left, they were granted eternal youth by Eternal Dragon of Namek. However, there is a limit to this power. The only way you can die is by having your heart removed from your body and destroyed.
Since Goku defeated Syn Shenron there has been no one left to challenge Vegeta other than Trunks. After two hundred years of boredom and training in the Hyperbolic Time Chamber, King Kai contacted the two warriors with some rather disturbing news. When the two arrived on King Kai's new home planet Kai told them that in the Dark Galaxy, a galaxy covered with darkness, demons, and devils, was preparing an army to attack and conquer the entire universe.
At first, the Saiyans thought that this wouldn't be much of a problem. Demons, devils, and other evil don't exactly sound very powerful, but then King Kai told them something thing that made them change their minds. It turns out that the leader of this army of darkness is an Arc Devil known as ArcOni, a devil well known to Vegeta. Legend says that Oni has the power to control minds and control a persons actions. The last warrior to battle Oni was Brolly, who he caused to rip his heart out and blow himself up.
Once Vegeta and Trunks heard this, they began to build a space ship to take them to the Dark Galaxy. While Trunks built the ship Vegeta continued to train in the Hyperbolic Time Chamber. Vegeta knew that he had to grow his tail back so that he could surpass Super Saiyan 3 and re-achieve Super Saiyan 4. He continued to push his SSJ3 powers to their absolute limits, and continued to bring himself to the brink of death constantly without concern for anyone else.
After spending three years of pure hell in the Time Chamber, Vegeta had grown his tail back and knew that it was time to put his power to the test and see if he could transform into a Super Saiyan 4. He took his space pod to New Namek and waited for nightfall. Once the sun had set Vegeta looked up in the night sky and stared at earth with a burning desire to ascend to a new level of power. At once the transformation into the Golden Monkey began, and soon after he transformed into what he desired most in life, the true form of the Legendary Super Saiyan, Super Saiyan 4. Vegeta was ready to begin the greatest war that the universe had ever known.
When Vegeta returned to earth, Trunks was putting the finishing touches on the ship and was getting ready to train for fifty years in the Time Chamber. Even though Trunks wasn't quite as powerful as his father he could still give a demon a run for his money, but a Super Saiyan 1 wouldn't be enough where they would be going. In fifty years Trunks would need to reach Super Saiyan 3, a level of power that took his father over one hundred and fifty years to reach. Could he reach a level that his father struggled to achieve? He would soon discover that in order achieve this kind of power; Trunks would need to fight the kind of demons that he and his father would be fighting.
Fifty years had come and gone, and Trunks had emerged from the Time Chamber with a secret that only he and the Time Chamber knew, but his father would soon know. The two began to make the final preparations for their trip to the Dark Galaxy. Once they had packed and made final adjustments to the ship, the last two Saiyans left in the Universe began a journey to a place that had horrors that would put Hell itself to shame.
The two of them packed their bags and set off for the Dark Galaxy. Little did Vegeta and Trunks know that before their journey was over that one of them would not be returning home ever again. Meanwhile at DarkBurst, the home world of the Devil Army, ArcOni began to plan how he would deal with this new threat to his ultimate army. One of his generals has found a way to deal with this problem: send someone from Hell who has a rivalry with Vegeta and send them to deal with him. "I will gladly deal with Vegeta."
"If you fail me then I will be the one who sends you to Hell again Nappa."
