There's nothing wrong with the cliches of evil governments or aliens; it's all in how you handle them. Look at what The Matrix: Revolutions did for the classic Man in Black.

Also it might be a good idea if you kept the playable character's transformations simpler so that they stayed close in model to each other (to make animation simpler) and left the large and complex transformations to end of level bosses (who are maybe female as well?) since they wouldn't need to be animated as much. Just tossing ideas out.
