Oh, it really bugs me when an antagonist is revealed to be less inherently powerful than the protagonist and that is implied to be part of what makes her evil. Because might makes right, of course.

Not to mention it's un-heroic not only for moral reasons, but also because, well, defeating someone weaker isn't impressive at all.

I think you meant to say "Therian Servant" there - you said a little earlier than you didn't like the term "Animal Servant"?
Whoops! I'm still used to calling them that because that was the term used in roleplay *goes to fix*
