#### Pre-Story Lore:

Rail was originally part of the Demon Clan of Namekians on Planet Namek. As part of the Demon Clan, Rail was taught that his people were magic experts and that they were Demons destined for greatness. Rail was brought up to be cruel and unforgiving, learning curses and torture-based magic. However Rail was never truly able to tap into the full potential of the magic, as his heart contained a certain level of purity. Despite truly wanting to embrace the darkness of his clan, kindness still remained in Rail's heart. As Rail grew up He became less and less impressive in comparison to the rest of his clan, as they were able to easily outdo Rail in everything magic related. However, the anger boiling within Rail caused him to realize something. One day Rail began beating down on a member of his clan who had mocked him, and it was here that Rail realized that He wasn't actually weak, just not ready for their magic.

Once Rail realized this, He began training himself to be stronger physically than the rest of his clan, that way He could never be outdone by them even if they had magic. However Rail's training was cut short, as one day the Clan Leader came to Rail and declared that they were banishing him to another planet due to his weakness and uselessness. Rail was given a seed, a small ship, and whatever He had in his home. Rail wanted to massacre his own clan for their disrespect, but the kindness left in his heart stopped him. Rail ended up on Earth. At first, it was boring. There wasn't anything to battle, and nothing to really interest Rail. Things changed though once Rail discovered Humans. At first Rail wanted to slaughter them, as He could tell that they were infinitely weaker than himself, but then He discovered Martial Artists, and realized that the potential Humans hold could be something amazing. Rail decided to take on several Martial Artists, failing miserably at defeating them each time. However Rail had a plan. Rail acted as a student, pretending to be loyal to each Martial Artist He was under, coming up with a schedule to where He would be training with four masters every day.

Once Rail had learned everything He wanted to, He was going to kill the Master and their Students, or at least that was the original plan. Rail had grew a genuine bond with these masters, and He hated that. The kindness within Rail had ruined his entire plan. Rail had an idea to purge the kindness from him though, as using special magic Rail could separate part of his emotions or personality traits into his offspring. Rail created Rail Jr., his Son who would supposedly have all of Rail's kindness and positivity. At first, it seemed to have work, as Rail was able to decimate his Masters and their entire schools with ease. Rail even forced Rail Jr. to be his servant, demanding that He become a powerful heir that would fuse the remainder of Rail into himself if He were to die so He could cheat death. Because of all this, Rail Jr. had a link to Rail's soul.

Rail built his own kingdom out of his first Master's Temple, having Rail Jr. make his throne. After serving Rail for a while, Rail Jr. began to reach adulthood, however Rail didn't want his back up body to become old, and used magic to revert his age and make him a child again. Rail Jr. decided He didn't want to live alongside his Father anymore though, and abandoned him. Rail didn't care though, as their souls were linked and if anything were to happen to his son He'd just fuse the rest of his soul to himself. Having much more alone time made Rail curious though, and thus Rail planted the seed that He was given by his clan behind his temple. The seed grew fast, becoming a giant tree bigger than a skyscraper in less than a day. This made Rail stand out, which He didn't mind at all. Rail grew very proud of his Temple, deeming it a kingdom. Rail was so proud, that He used his old ship to contact his clan. Rail bragged that they were far superior to the race on the planet, and that the whole world could be theirs to rule over. Many of the Demon Namekians were against listening to Rail, however some were very interested and made their way to Earth.

Upon arriving, Rail made it clear to them that He would be their King, and that they would serve him, but also be able to treat Humans like trash. However when some of them started bringing Humans to the tree and executing them, Rail realized that his kindness was not entirely gone. He had a soft spot for these Humans, yet He had no idea why. He had a strange urge to help them, yet He also had a strong desire to rule. Rail killed a few of the other Namekians that were killing Humans, and decided to take a stand. He declared that He would bring Humans in via special Tournaments, where they would test the strengths of the Humans and watch their improvements over time. It allowed for Rail to avoid killing Humans without reason, and for the other Namekians to be cruel. A new problem arose though, as the tree Rail planted had spiraled upward so far up that it was visible from space. There were also strange fruits growing from the tree. Rail investigated the tree, and realized that with every death caused by him, the energy from his victims went into the tree and caused it to grow. Not only that, but the fruit growing on the tree could grant major power boosts. Once Rail explained this to his Kingdom of Namekians, many of his servants started spreading the information throughout space behind his back, spreading rumors of the Power Tree. When Rail found out about the rumors, He slaughtered the traitors and used magic to place an enormous barrier around the tree, making it so nobody could see the tree except those who got close enough.

After all of this, Rail was beginning to grow a bit old, but He maintained his power with training and consuming fruits from the tree. One day though, Rail got a strange feeling from his Son's Soul. When Rail investigated, He discovered that Rail Jr. had been training himself to be the protector of Earth, similar to how Rail saw himself. Not only that, but Rail Jr. had created a set of Dragon Balls for the Earth. At first, Rail was furious. but He quickly calmed down when He thought about what Humans could do with the dragon balls. Rail thanked Rail Jr. for creating the Dragon Balls, before aging him down one more time and returning to his kingdom. From then on, Rail continued his tournaments in which He would find the strongest Martial Artists of the time and try to break them either mentally or physically, so that way they could either be sacrificed to the tree or let free to become a worthy fighter for the human race.
