Wolverine helps foil a plot to undermine the Catholic Church by installing a Shadow Pope who has a mind-control device that can make everyone Catholic. 

This is the scariest plot I’ve ever heard of!

Logan fights his way through Church assassins in the sewers of Vatican City and saves the day.  The conspirators survive but, thankfully, never reappear.

It’s also dumb, and suffers from changing writers midway through.
