Chapter 1: The Tragedy
Toby could feel the electricity coursing through him; he could barely withstand the pain. Why was this being done to him? He had followed the advice of the one he looked up to: listen to Sayer, but now for some reason he was being electrocuted. Above his screams of torment though, he could hear bits of what was going on, and after a while, something else was said that shocked him even further. Sayer had apparently told the people to increase power. Toby was hoping that the assistants would be able to talk some sense into Sayer. The electricity was still quite violent, causing him excruciating pain, and Sayer could be heard above his screams saying "no use" and "don't care". Even more electricity started coursing through Toby, the pain was too unbearable, having forced his eyes open, and his screams were louder than ever. Seconds later, blackness clouded his vision instantly, and the pain ceased.
The blackness faded, and Toby could see himself dressed in a white robe, in a queue of people. As he stood up after finding himself on a flat surface, he wondered to himself why he got what treatment he did from the people he trusted.
"Sir, please take your place in the queue," someone spoke.
"What?" Toby shouted fearfully, turning to see a pale-blue skinned man with small horns.
"You need to get in the queue to see King Yemma."
"King… Yemma? Where am I? Where is Sayer? Where is Misty?" Toby shouted, panicking. He had to get back home!
"He needs not join the queue!" a voice commanded. It sounded like it was either gravel or something burning. Toby turned to see what seemed to be a red human-dragon type monster coming towards him from behind him, hovering above yellow clouds.
"And why would that be, mister?" the blue man demanded.
"Because I am willing to take him back!"
"That is not for you to decide!"
"It is. This boy is blessed with four stars!"
"Wait, so that means-"
"Yes, now leave us!"
"Thanks for chasing him away mister, but who are you, and where am I?" Toby asked the stranger.
"I am Nuova Shenron, and you are in the next world, Otherworld. You are by a long line going into the office of the judge, King Yemma"
"Did I die, Nuova?"
"Unfortunately, yes. However, should you so wish, I can bring you back to life."
"Please Nuova, can you please take me back. I have a sister and I need her to know that I'll be alright! I'm not ready to die!"
"I will try, but there are complications. First of which is, to get back to the living world without the permission of King Yemma, we will need to fly to a specific location in this realm. Second of which is that your body will revive in a new location dependent on the whereabouts of an artifact I'm linked to, an artifact called the Four-Star Dragon ball."
"Please, just get me back home! I don't care how, just get me back!"
"Very well."
Nuova then lay Toby down in his arms, cradling him. With that, he flew off. The flight seemed to take forever, as they flew along the path that must have been flying away from King Yemma's office. The trip took what seemed like days, maybe weeks, and by the end of it, they had arrived at a lone rock peak above the yellow clouds that was host to a mysterious object. It was an orange ball with four red stars. Nuova set Toby down on the rock, picked up the ball in his right hand and told his charge to grab the ball. Toby clutched it with his left hand, and the color of the ball changed: the orange ball became blue, and it seemed to dig in to his hand. Blackness enveloped him, and when vision returned, he found himself in a completely strange place. It was a small cottage in the middle of nowhere, and he was faced with two individuals. One was a scared child that had strange hair, and another was a muscled man on his guard who also had the same hairstyle.
Toby was confused as to why they were acting this way, but then Nuova's voice asked him if he could take over. He agreed, and immediately he felt his body begin to change. Soon, the two strangers were faced with Nuova Shenron's body instead of Toby Tredwell's.
"Is that you Nuova?" asked the man.
"Yes Goku, it is me," Nuova responded. Toby, who could still see what was happening, was surprised that Nuova knew this man.
"Why are you here Nuova. It's been almost one hundred years since our last wish was made!"
"That wish had enough power to revive all of the Shadow Dragons, but we were a lot weaker than we were originally. We had no bodies of our own, so we had to plant ourselves inside humans to survive, living off their negative energy."
"Does that mean that the Dragons could grow even stronger than before?"
"No Goku, the negative energy inside their hosts is barely enough to keep us at our original strength. However, we were given even more negative energy by the humans recently. We became parasites, forced to take bodies of the living."
"Nuova, I never thought you'd stoop this low, taking a young boy's body!"
"It was necessary Goku. I myself swore that I would never possess a human against their will; that I would survive as a speck of negative Dragon ball energy and an Otherworld spirit, but I had to break that promise recently."
"Why?"
"The boy I am possessing was unjustly murdered by someone who desires nothing more than power. If necessary, we can bring our hosts back to life at the cost of sharing our life force with theirs, so I made him mine at the last second. I couldn't let him perish so early in life. The flame has only just started glowing, so it deserves not to be extinguished at this stage."
"I see you still retain some of your good heart, but what about the child?"
"Toby and I will share control. I will also train him in not only the ways of battle, but also his psychic powers, the lack of which being the reason he was executed."
"Nuova, can I ask one more request?"
"Yes Goku, proceed."
"If the Shadow Dragons have truly returned, then everyone will be in danger and there exists a very high possibility that the universe could be destroyed. Can you please find and destroy them?"
"Very well Goku, but you should know that they now possess humans and therefore live among them, so expunging them will be difficult."
"As long as you extract the dragon within before it takes over their being, you should be able to save the host, judging from what you told me, because the host's life in that case is not directly linked to the dragon's life."
"I shall do this, but first I need to train my host's combat and psychic abilities."
Just then, four figures appeared on the horizon, namely a humanoid green woman, a walking frog, a bird-like humanoid and a giant boar. Gasping with surprise, the child with the same hairstyle as the man identified them as Mamba, Susha, Torga and Lord Yao respectively. He also revealed that they had dangerous intentions, especially Mamba who, according to the child, had managed to regrow her hair. They themselves stated that just because a kid could turn his hair golden was no reason to be afraid, after which they charged, but stopped when Nuova appeared in front of them.
"Let us handle these four," he spoke to Goku and the boy. First to attack was Torga, who immediately bear-hugged him. Nuova only smirked, and soon the bird's arms and front were set on fire. Susha then attempted to head butt him, but as soon as his head came into contact with Nuova, it also burst into flames. Toby found himself both amazed and amused, not only was Nuova holding his own against these monsters, they seemed to be far out of his league. Mamba then attacked, ensnaring Nuova with her hair, but it also caught on fire, leaving her bald, which caused her to chart entire new galaxies of fury. The three people who were attacking then tried to gang up on him, coming from three directions. As soon as they were close enough, Nuova moved very quickly to a point above them so that they all rammed into each other, after which he charged a ball of fire in his hands. "Nova Star!" he shouted, and threw the ball of fire at the three attackers, incinerating them in an explosion.
Lord Yao seemed quite impressed by this display of strength, yet disgusted that his minions were too weak. He then attacked Nuova, who instantly vanished and reappeared at another point. He then brought his hands to his shoulders so that the left hand was on the right shoulder and vice versa, and created a lens. As Yao found him and charged again, it happened. "Nova Death Ray!" Nuova shouted, after which a beam of intense heat shot right through Lord Yao's chest. He then threw another Nova Star at the demon lord and vaporized the rest of his body.
Nuova's body then distorted and shrank until it was in the form of Toby Tredwell. Nuova then told Toby in his mind to look at his left hand and not freak out, which he did so. He found a large blue ball with four black stars embedded into his hand, half of the diameter sticking out his palm and the other half out the back of his hand. It seemed to be the same ball touched while he was in Otherworld. Nuova told him that this was normal as this was where his dragonball (which all seven Shadow Dragons possessed somewhere on their bodies) was located. Goku told Toby not to worry as Nuova Shenron was the only Shadow Dragon that could be trusted. He also left him with a request: when everything was done, would Toby leave the four-star Dragon ball in his great-great grandson Goku Junior's possession as a memento?
Goku Senior then vanished as a helicopter arrived. Toby met Pan, Goku Junior's grandmother, and probably his friend Puck. After a brief goodbye in which Toby promised to stay in touch with Goku Jr., he moved to a remote area in which he started to train. It would take a while, but when he would encounter the Shadow Dragons, he'd be ready.
