(Goku Black took your body AU)
You and the other Z Fighters, including Vegeta, had gone to Trunks’s future to defeat Zamasu and Goku Black.. but the problem was that the Zamasu in your body had stolen it after killing you in another timeline. This made Vegeta SICK with rage.. He believed that one’s strength came from intense training, fighting and years of effort and hard work.. but since Black stole your body, Vegeta’s mind clicked it as him not earning your saiyan power and strength..
When Vegeta began to pummel the Zamasu that stole your body from another timeline, he was in Super Saiyan Blue as he began to scold the imposter, angry on your behalf..
“This stolen body! Every muscle, every CELL.. their body was built from a LIFETIME of intense battles! But you took it! It’s all secondhand! You feel the power in those saiyan cells but you don’t TRULY understand it! Because YOU DIDN’T BUILD IT!! AND YOU’LL NEVER LEARN TO THINK LIKE THEM!!”
He shouted before delivering a Final Flash to the imposter of you.. he was still fuming, but you could tell that he meant every word.. He had learned to respect you over time due to your efforts..
