Counterfeit Religions: Space Johos

Space Johos are a false cult/Poo-poo religion. The try and piggy-back on the popularity of the true Martian Religion by dressing like Martian Missionaries. Space Johos do not use the Book of Martian and instead have their own false and stupid book called the Bibliography, or something stupid like that. They will try and steal our investigators and tell them that the only way to understand their false book is to attach a space brain-sucker-leach to their head.
Sometimes Sentient-creatures/robots will confuse Space Johos with our own true missionaries. The way to tell the difference is that Martian Missionaries wear a name badge that clearly identifies them with The Church of the Martian Saints Incorporated. And if/when Space Johos wear similar name tags, the way to tell the difference is that Martian Missionaries carry the Book of Martian, so always ask to see their Book of Martians.
Do not try and preach to Space Johos! They are some of the lowest of the heathen-gentile-creatures, and have been condemned by the Gods to be thrust into the blackness of the Nizlack-Worm's entrails after the great judgement of the galaxies.
The command from Martian Church HeadQuarters is to slay Space Johos whenever you think you can get away with it. For it has been written "Let their blood, whatever color it may be, be shed. For behold, their abominations have kindled mine anger against them. And lo, I shall be with thee. Amen"
