This "Alien" power loader Halloween costume is...  uh...  incredible. 

Ben Hallert created his own power loader costume and kept an online journal of his progress.  He also included tons of pictures from start to finish. 

Sorry, a tough chick isn't kicking alien butt with this power loader -- You'll have to watch the movie for that.

If you're interested in building your own power loader try this one on for size -- tough chick included.
