heres a good story:

 

a woman is born with incredible force powers and shes this jedi trainee. then the sexually frustrated sith guy kidnaps her and rapes her repeatedly. after that she gives birth to the ultimate force baby. howeve, the planet theyre on explodes during a jedi invasion. the baby is dumped in a spaceship and then ends up in a jungle planet and is raised by a bunch of savage ape men. then one day a ship of humans arrives on the planet and then they slaughter the ape dudes and then seeing the teenage kid they take him with them to their own planet... and then the story begins!!

That would be one heck of an intro.

doesnt need to be though. the part about the ape men could be in the intro, then you find out about your origins and mother/father later on. that would be a great plot twist/revelation. it can even be one of those "i am your father" things.
