Intriguing Endearment [Vegeta x Bulma] Dragon Ball Z Fanfiction

He was known as a ruthless and feared murderer from the Frieza saga. Yet; similar to any other beings that breath and feel like the like of him, he too had the right to live and to experience. Unfortunately, his free will had been abstracted from him as he was turned into the world's most dangerous threat's minion. His past came rushing back to hinder with his present. Was his saiyan pride and resolve enough to help him get rid of his demons?
He was a monster and he'd acknowledged it. Not because he wanted to be one but because he was made into one after the destruction of his planet Vegeta-sei and the death of his father from the hands of the almighty vilain of all time, Frieza. He'd burned with the desire to avenge his family and people for he; as a fallen prince had to fulfill the duties bestowed upon him. But when a certain Kakarot had surpassed even him, the prince of all saiyan; his frustration had run deep within his flesh about the fact that he'd failed. Failed as a prince for he didn't succeed in extracting his revenge on Frieza. His pride was hurt and his frustration rang a bell constantly through his ears. He needed to surpass the said Kakarot if he wished to regain control of his destiny and most importantly of his revenge. There was no other option than to defeat the one who defeated his ultimate enemy and to make his ancestors proud. He needed to train harder so as to achieve the legendary transformation of his race and beat Kakarot and obtain his satisfaction. This was his ultimate goal. The only reason that kept him alive; his pride as a royalty of saiyajin.
When he was offered an opportunity to live with the genius family of a certain woman who had help create a bizarre machine that would enhance the capabilities of a saiyan through gravity, he seized the occasion to progress deeper in his training and once he was done, he'll beat Kakarot and rule the world. Of course, he knew no one on earth liked him. But it didn't matter.
