Well, in such a fanfiction, Tsukune would likely inherit the typical Saiyan traits. He could have an insatiable appetite for battle, like real Saiyans. His appearance might also change a bit to incorporate some Saiyan features. Story - wise, he could travel between the Rosario Vampire world and other Saiyan - related places. He would probably face discrimination at first in the Rosario Vampire world for being so different, but then prove his worth through his amazing powers.

For example, his relationship with Moka might become more complex as he has to balance his new Saiyan identity with his life in the Rosario Vampire school.

There could be epic battles against villains who are also a combination of threats from both universes. And his character arc could be about learning to control his new powers and use them for good, all while still being the Tsukune we know from Rosario Vampire.
