The power of man and the new story are about the only ones i have read, and i thought they were very well written and intriguing. I cant understand why you seem to dislike the power of man, it is a great story.
I have also met Salazar(or maybe one of his drones) in space twice, and both times i was struck by how unlike the steryotypical madman/mass-murderer he is, which is very good to see/hear/read!
Amazing work, and i cant think of any way to make him better, only develop him into the symbol of fear that he deserves to be!
