*forehead slap* Oh man, Capcom. Allowing Cain to control the Hunters through three uprisings is one thing, but then saying the Hunters are hard to lead? WTF? Why? How is it different from any other armed organization? ARGH.
I can see Cain being on many reploid councils, or deemed a reploid 'expert', though. Especially since they retconned him to being an actual scientist and not a biologist in MHX,
