[@Mia] I absolutely love your first idea. I think it has the potential for plenty of action, drama and romance. The whole idea of the two of them leaving their own planet for another will provide lots of adventure. Perhaps we could add a small part of your second idea in to the first and still have one the aliens be a member of royalty in the their home land. Maybe he/she has been chosen by his/her father, the dictator of their home land, to bring justice to this rogue Alien, who is causing chaos on planet Earth? He/she is accompanied by his/her father's most elite warrior of his guard?
