I had a character already in mind, being the alien sent to earth it wants to warn the earthlings of an oncoming threat that is coming to earth. A band of power hungry space creatures are traveling from planet to planet taking over everything and now they have sights on earth. My character barely escaped as it's own home planet was taken over and enslaved by the other aliens that are taking over all life. 

That is the direction I like to go with it, but I am happy to hear what you have in mind as well.
