I'm curious if it is possible to make an animal companion hawk, eagle or some other predatory bird, to be a mean, flying killing machine that kills anything* that you point at, of course in one attack.
You can use any official 3.5 and PF material. It has to be an animal companion from a 20 level Ranger (or Ranger + PrC). It doesn't have to be an animal if other types are available, it just needs to look like a predatory bird, preferably hawk or eagle-like.
* By saying "anything" I mean any tougher then usual mook, but of course the more powerful enemies he can kill the better.
Is it doable?
