a/n: Skipping the bio with this story. You have the same outfit as Future Gohan and same abilities. You also lost your arm in a battle against the androids. Now the question is what universe would you like this to be set in.
DBZ/DBS: You're set in an alternative timeline where you're the son of Future Gohan. Both Future Gohan and Future Trunks are dead. This story will have a lot of perks that the RWBY universe doesn't.
RWBY: In this universe there's not as much fighting. Besides androids, you don't have any challenges and can basically speedrun the series after the androids. But no going into space, no Beerus, no Z Fighters, no Frieza or Broly, and no Dragon Balls.
Both: New set androids on Remnant. New enemies arrive on Remnant. Space adventures. Basically Remnant will become part of the Dragon Ball Universe.
