I think you mean to say "Who is the Emperor of Islam", and there's no such thing, at least in the present day. The Prophet Muhammad (peace be upon him) led all Muslims, and after he died there was Abu Bakr, Umar, Uthman, and Ali. Then the Shia split off and things split up. Today you have political leaders- kings and presidents- who control different countries, and religious leaders- sheikhs and imams and such- who have followers, but no real control over them.
So yeah, Islam doesn't have any centralized authority, like Catholicism does.
