This is an In-Between Story. Meaning it's a story that has taken place in-between two current stories of the main timeline.
Turn Back The Clock
Many adventures with Vegeta and the Z-Fighters await Toushiro Hitsugaya in the future. But for now, let us stop the clock and turn the hands of time back a few years, back to a story that was written in time, but never told.
Until now.
It was a few months before the Winter War with the Arrancars and Sosuke Aizen when a strange message arrived from space. It was a message to all planets with warriors that had supernatural abilities. One warrior from each planet was to go to the designated planet as their planets ambassador to discuss planetary alliances and galactic peace. The host of this meeting... The King of All Saiyans. Being the strongest on earth, Goku was given the message. When he first read the message that was given to him, he was shocked to hear that the saiyan race was alive. How was it that a planet and an entire race that had been destroyed by Frieza had come back? The answer was back during the battle on Namek. A wish was made on the Eternal Dragon, Shenron, to bring all of those Frieza had killed back to life. The wish was granted and all of Frieza's victims came back to life. But that wish had, unknowingly, stretched farther then Namek. It undid all of the evil things that Frieza had done over the years, including restoring Planet Vegeta and the Saiyan Race. Having gotten word about Frieza's death at the hands of a saiyan King Vegeta, Coge, Tarble and Vegeta's father, decided to hold a meeting to negotiate planetary alliances and galactic peace with other planets now that they no longer worked for Frieza and his goons. Having grown up on earth, Goku knew nothing about how to interact with his own kind. He feared that he'd do more harm than good if he went as a representer for earth. Especially if or when they discovered he was a saiyan born as a low-rank under the name of Kakarot. But Goku had a trump card. If the saiyan race were the ones hosting the meeting, why not send their chosen prince? So Goku brought the letter to Vegeta himself and told the prince why he didn't want to go. But Vegeta didn't want to go either. He had given up his old life as the Prince of All Saiyans and was enjoying his life on earth much greater. However Genryusai Shigekuni Yamamoto, Head-Captain of the 13 Court Guard Squads, said that he would send someone instead, saying that he had a plan that involved the Winter War. A Captain's meeting was held soon after with Goku allowed to join.
And this is where our story begins...
