Chapter one (HP DBS)

After 500 long years, Harry Potter, along with Earth and its many lifeforms, had finally died. Harry had been long resigned to Earth's fate... he tried saving it, of course. He advanced farming, killed dangerous people and groups, reduced the population, and even ruled some but it was all for nothing.

"Oh, I wouldn't say that, Hadrian," Death spoke in Limbo. "You bought Earth centuries with your suffering and hard work. As a reward I would like to give you a second life."

"Re-live my life on Earth? No thanks." Harry replied.

"No in a new multiverse as part of a warrior race called Saiyan's. You would get to keep your magical power and have potential for more and have access to Ki, also known as Chi and Qi, with your Ki from this life also being carried over."

"Tell me more then," Harry said, intrigued by an entire new multiverse.

"Well, I was originally going to offer you a Gamer power but you suck at games... I will be giving you several enhancements as a reward for your actions in this life."

"What benefits?" Harry asked.

"The ability to learn Ki-based techniques far more easily and you'll have a lesser version of the Legendary Super Saiyan power, the Pseudo-Legendary Saiyan. You'll be born with a power level of 5,000 and will have access to something called the Wrath State, a 10x power multiplier, without the constant eruption of power, an improved version of Saiyan Power, an adaptive ability for power, skill, and durability, and have a stable power level and all without damaged sanity. You will have the ability to innately control your energy to hide your true power, an ability similar to Ancient Saiyan's for another benefit; Super Saiyan 3 Full Power form, and since you're basically a demigod you'll have Godly Ki and be on the lowest level of divinity along with access to the Super Saiyan God form once the Super Saiyan form is unlocked."

"That seems like alot," Harry commented, most of that going over his head.

"Those were originally going to be Perks buyable with points. There are quests also, but I'll just plant the knowledge into your mind as suggestions while omitting the XP rewards. Any questions before being reborn?"

"Can I grow into an identical penis size in terms of length and girth?"

Death sighed in annoyance. "Of course."

"Then I'm ready to be reborn," Harry said.

Everything suddenly turned black as 'Harry' ceased to exist.

Being born while fully cognizant was a shock for him, but at least he was given a cool name... Caesar. Eh, it was tolerable anyway. Caesar was born extremely powerful and began training and fighting as soon as he could walk and talk like all of the other Elite Saiyan's.

The life of a Saiyan was hellish though and Caesar was fighting fully grown Saiyan's because they were the only ones who could handle him. Caesar's power level grew from 5,000 to 75,000, and then all the way up to 1,500,000 by Age 700. Sadly Caesar was forced to begin training his elder brother at his fathers urging, but Vegeta wasn't very devoted to his training and he wasn't a threat to him. Vegeta, like most Wizards, was prone to arrogantly believing that he was already extremely powerful and needed no further training. Caesar probably wasn't helping with his lack of aggression towards his family and closest allies.

Caesar was very interested in developing new abilities though and with Death's guidance had invented a technique called the Power Ball to aid them in their war against the Tuffles and had accessed something Death had explained was called Instantaneous Movement while trying to apparate.

With Vegeta having offered him Lordship over a city and area, Caesar had agreed to take part in the planned Saiyan-Tuffle that his brother Vegeta wanted to start decades early. Caesar was somewhat ashamed to say that he accepted it with little hesitation, but it was done and would be done either way.

And so began the Saiyan-Tuffle War, which was a misleading title with Caesar's presence... Caesar joined his fellow Saiyan's in the slaughter with his Wrath State; all of the power of a Great Ape without being uglied up. It wasn't a challenge, Caesar had trained insanely hard and he was now a mass murderer with few real rivals, but he took an entire city and many Tuffle prisoners for soul absorption... Caesar had soon learned to clone, manipulate genetics, engineer, and countless other things that Caesar had only dreamed of in his previous life from their minds. The so-called war lasted a year and Caesar invention, the Power Ball, had allowed thousands of Saiyan's to completely eradicate all of the Tuffle's and the technique was now a staple technique of the Elite Saiyan's.

Caesar left the war with an intact city, hundreds of citizens, a lot of useful technology, and a stable stream of tax revenue and a lot of spoils.

With the planet taken in the name of House Vegeta, they began constructing new homes and a civilization while preparing for external conquest and mercenary work. Caesar, however, was constructing himself a spaceship with his new knowledge and training areas so that he could continue growing his power in secret.

It took him decades of training, but Caesar had unlocked Super Saiyan forms one-through-three and had a power level of 20,000,000. The Saiyan Army was ready to take on missions and had been conditioned to spare cities, fields, forests, and generally anything of use depending on the customers wishes.

Eventually in Age 730, Caesar and the Saiyan's approached the Arcosians with an offer...

"Greetings," Caesar drawled.

"What do you want, Saiyan?" An Arcosian asked with a hint of fear.

"Right to the point, good. I've noticed that your people are struggling on this planet, over-populated, poor air and ground quality, damaged ozone layer, radiation, and many cities are in ruins. I've also noticed that your race lacks the power to conquer another planet for yourself... but you have useful technology that we need." Caesar paused as the Arcosian's realized what he was offering. "Pick a planet and we will conquer it for you in exchange for this technology." Caesar handed the Arcosian leader a list.

"This is reasonable in exchange for a new planet," the leader agreed.

"Good," Caesar replied. "We'll need to know in advance if you want any specific features spared, but fields and forests seem obvious as something to spare."

They began negotiating the details with the planet being selected, five cities were to be spared, an advance on the body armor was given, the features to be preserved were all stated, and a bonus for early completion was agreed upon. Now all that was left was to conquer them a new planet.

Caesar obviously accepted the terms and then he mobilized teams of Saiyan's to cleanse and capture the planet with himself at the head.

The conquest was over quickly and the race inhabiting the planet was ruthlessly exterminated down to the insectoid children... Caesar, however, was opting for precision, levitating the beings up and then killing them with Ki attacks or physical combat to minimalize damage to the world. Most of the other Saiyan's weren't so refined, but the job was soon done and the payment was given for early completion, all features spared, and all undesired lifeforms terminated.

With the Saiyan's now a known power in the universe, Caesar knew that King Cold and his worthless family would cross them soon enough and that meant that Caesar needed more power and resources.

Age 731.

Caesar had spent the year mastering the Super Saiyan God form and Ki control, and his newly unlocked form; God-like Saiyan, but he still wasn't able to fight the God of Destruction Lord Beerus safely according to Death. Still, all Caesar had to do was stay under Beerus' radar until he went to sleep and then he would have 47 years to train according to Death... maybe even learn from Whis during that time. But what was currently plaguing Caesar's mind was King Cold and his family wanting them as servants.

Frieza and his family needed to go, they were stupidly reducing this universes Mortal Level out of greed and lust for power, and Beerus was allowing it out of incompetence. Caesar was trying to convince his brother to attack the ships blockading Planet Vegeta.

"See reason, brother. They mean to either destroy us, exploit us, or outright enslave us. Death is preferable to any of those options."

"The Cold Force will destroy us if we resist and will likely send us terms soon," Vegeta spat in reply. "If we bide our time than we can at least overthrow them later."

"But until that time we will be at their mercy and under their command. They already have massive numbers at their disposal and will likely gain even more... I'll fight Cold and his accursed spawn myself if that's what you're worried about and if I die then you can just label me a rebel against your authority." Caesar replied.

"Which you seem to be already doing," Vegeta replied coldly. "Perhaps I should just punish you now."

"I'm not rebelling against your authority and the worst that I would do is simply leave Planet Vegeta in self exile rather than humiliate myself as a servant to a lesser being. As for your threat of 'punishing' me, I'm far stronger than you and your so-called elites combined power and I won't suffer an attack from anyone on my person. I was born stronger than you and I've always remained stronger than you. We would be savages living in ruins if I hadn't interfered to have the cities spared... House Vegeta and House Caesar are both extremely wealthy due to our well trained army that I oversaw the training of and all of the lucrative deals that I negotiated for maximum benefit. Brother, don't sacrifice everything that we've built by bowing."

"I can't risk our races future solely on your shoulders," Vegeta replied. "You can exile yourself if you wish, but don't ever come back. I won't welcome back those who lack faith in my ruling abilities."

"Fine. Enjoy being a slave." Caesar replied coldly, causing Vegeta to twitch as if he would attack. Vegeta wasn't that stupid. He knew that Caesar wasn't bluffing about his power... Caesar always trained, fought, studied, and planned obsessively.

Caesar returned to his castle and retrieved all of his wealth, training aids, his clothes, and generally anything that he wanted and placed it into his magically expanded bag. With all of his things packed, Caesar used Instantaneous Movement to travel farther away from the Cold Force's area of influence, arriving on a distant planet marked to be a possible secondary home world for the Saiyan race.

Guided by the knowledge implanted into his mind Caesar traveled first to this universes Earth to climb up a tower, catch a sentient cat, drink some 'Ultra Divine Water,' and then retrieve Senzu Beans and seeds to grow his own battlefield medicine. The Ultra Divine Water would strengthen his Godly Ki and unlock even more of his potential.

After that Caesar would travel into Other World and persuade King Kai to train him and teach him the Kaio-ken, Spirit Bomb, Telepathy, Far-Seeing Arts, Magic Materialization, and Hypnosis.
