I don't own DBZ yeah, yeah, yeah.
The Genetic Saiyan Chapter 1- Fight For Earth Begins!

Goku and Caracas stood there, floating, not saying a word. Goku was still stunned from his attack against Gohan and Goten.

"Now back to where we were" said Caracas, "Ah yes, I, Caracas, was created by Dr. Gero's computer."

"Don't tell me his computer is STILL creating things to destroy me!" Goku said, shocked.

"Yeah well it barely had enough juice to create me. I had to train for years to get to my maximum." Caracas stated, cracking his knuckles.

"Well I can't say it did that well of a job." Goku laughed as he put his hands on his sides. Caracas clenched his teeth and tensed his muscles. Goku dodged Caracas attack barely that seemed to happen in the blink of an eye. Goku looked at Caracas fist beside his face. Then Goku threw his own punch at him in which Caracas dodged as well. After that they began to throw punches and kicks at light speed. A few minutes after that Caracas finally landed a punch in Goku's gut. Goku bent down to hold his stomach when Caracas uppercut slammed into his chin. As Goku went flying back he caught himself and attempted to slam his knee into Caracas but he withdrew his sword slightly blocking Goku's attack. Goku pulled back and Caracas pulled out his sword completely and slashed from the left to the right narrowly missing Goku's face. Caracas, upset at his miss, began to slash furiously at Goku but Goku dodged all of them. Caracas got fed up with this and jabbed forward in the blink of an eye. From the side it looked like Caracas had won but Goku had moved to the side and had his hand around the holt of the blade. Goku took his other elbow and slammed it onto Caracas hand, nearly breaking it. Control of the sword now belonged to Goku. He took the sword and threw it behind him. It flew for about a mile until it slammed into a mountain.

"That was a god damn diamond plated sword!!" Caracas said. His anger had reached a peak of this battle. He let out loud growls. He spread his arms spread out, his fists clenched. The sky turned black and yellow lightning streaked in the black clouds. Goku slowly backed away from the hell bent Saiyan. Caracas pupils disappeared and his muscles doubled in size. His hair flew up and turned golden. The teal t-shirt he was wearing was ripped apart by his still expanding muscles. His fingers shot apart by lightning shooting out of them striking two nearby skyscrapers causing them to collapse. In a flash of white light, Caracas stood there, perfectly straight with his arms crossed. He had an evil grin on his face and his pupils were still gone. A golden aura surrounded him, making a loud humming noise. His muscles were now at least quadrupled in size. Caracas let out a light chuckle and disappeared.
