Well, it looks like I'm going to try to start updating this again, so here's the third installment to the story. Again I do not own Dragonball Z.

Chapter 3: The Training begins
"All right, now that you both are ready we shall head to my planet to start your training." said Shin. "Now I need both of you to grab onto me, and then I'll transport us to my planet."Vegeta and Goku both do what the Supreme Kai said and hold on to him. They were instantly transported to the Supreme Kai's planet. When they got there they were not expecting a tall pink man standing there.
"Master what are these people doing here?" Kabito asked. "You of all people should know that no mortal is allowed to step foot on this planet."
Shin replied," I know Kabito, but Vegeta here is part of the royal bloodline of the Saiyans, and he might be able to defeat the evil that is approaching. I think that we can let these two stay here if it means surviving this upcoming battle."
"Very well then master." Kabito said. " However you two will not be staying here dressed like that." Kabito then gave Goku and Vegeta new clothes.(the same clothes Gohan wore in the show)
Vegeta looked on in horror at what he was wearing. "I am not about to wear this ridiculous outfit!" Vegeta exclaimed." This outfit is even a disgrace for Kakkorot over here to wear."
"I don't now Vegeta; I kind of like this outfit." Goku replied.
"I take back what I said, Kakkorot does deserve to wear this stupid outfit, but I do not!"Vegeta angrily said.
"Vegeta, if you are ever going to reach the power of the Legendary Super Saiyan, you are going to have to swallow your pride, that includes wearing this outfit." Shin told Vegeta. "Now lets get started with your training. Vegeta, before we even try to get you to SSJ5 you are going to first have to achieve the level of SSJ3 that Goku can already transform to."
"Vegeta, for your first task you are going to fight Goku." "In order for this to work you two are going to have to go all out on each other" Shin said to them. "Now let's begin"
"Finally Kakkorot, this is my chance to finally defeat you once and for all." Vegeta said to Goku.
"Let's just start the match Vegeta." Goku replied. They both powered up to their max and flew towards each other. Vegeta attempted to deliver a blow on Goku, but Goku was too fast and was able to deliver a punch to Vegeta's face and sending him spiraling toward the ground.
"Come on Vegeta is that all you got?" Goku asked." My wife could fight better than you and your supposed to be the prince of all Saiyans."
Vegeta was instantly enraged and shot a Gallic Gun at Goku. However Goku easily deflected the blast. and sent a Kamehameha wave straight at him. Vegeta could not block this attack and was sent deep into the ground below. He felt like he would never be able to get up.
"Vegeta you're so sad." Goku mocked. "I can't believe Bulma has stayed with you as long as she has. She should leave you and come live with me. "Goku smirked a Saiyan like smirk. Vegeta could not believe what he just heard Kakkorot say. As Vegeta's anger started to grow so did his power level.
"Kakkorot! How dare you say something like that! I'll make you pay dearly!" with that Vegeta's hair started to grow longer and his eyebrows disappeared. Then finally he stopped and he was now at the level of SSJ3.
Goku smiled.," Way to go Vegeta, I knew you could do it if I pushed you a little bit."
Vegeta was shocked" You mean to tell me what you said was just to get me to the next level?"
"Yep." Goku replied
"Kakkorot! I'll kill you!" Vegeta exclaimed and lunged at Goku. Before he could do anything however Shin appeared between the two of them.
"Vegeta, like i said before you are going to have to swallow your pride, and that means NO KILLING GOKU!" shin exclaimed. He then calmed down and started talking to Goku and Vegeta once more." How about we take a break to eat?" Shin asked them. However st that time Goku and Vegeta's stomachs started to growl which answered Shin's question.
