Mates (Vegeta x Goku)

A small child with a tail once landed on the Planet Earth. A kind and gentle old man found the child once he landed, and decided to take him in, and named him Goku. At first, the child was very aggressive and wanted nothing to do with the man. Suddenly, the boy fell off a cliff! No normal child would have survived, but the boy was alive and well. Although Goku survived because he wasn't from the Planet Earth, the old man thought it was a miracle! The boy was a bit less aggressive, he was happy, and an overall caring child. Goku was only aggressive if he didn't know the person or if they were being rude and/or a creep. One day while eating dinner with his 'friend' who he likes to call his grandfather, he was staring into the moon. Suddenly, he transformed into a big ape! He was weak since he was only a few years old, but when he transformed, he had a great increase. His grandfather was a bit stronger, but just barely won the battle. He then realized Goku had great potential! In his eyes, Goku could become a fine warrior. So, he decided to start training him. At first it started off easy with sparring and Gohan holding back most of his power, but Goku easily caught up. Each day it got harder and harder until it was Goku's 5th birthday. Gohan threw him a small party, and surprised him by giving him an orange orb with 4 stars on it. Goku cherished it, knowing his grandfather wouldn't be alive for much longer. He was already 64, there's no way an earthling at that age could live any longer than 30 years! Another year later, Goku is now 6 years old and his grandfather had passed away. Goku was of course upset, but quickly got over it knowing his grandfather doesn't like seeing him cry. One day, our friend meets a young woman with blue hair who goes by the name Bulma.
