Maybe I misread or underread the the story, but how did Apollo wind up as king of the gods? Did he just sit on the throne? What exactly did he do that any of the other deities and demigods - Poseidon, Hera, Diana - couldn't also do?
I was also a little surprised that he could turn Hera into a mortal. If Zeus could do that, you would think it would be a pretty effective threat against her - and could save his paramours a children a little hassle.
Were there explanations that I missed?
