After the disastrous Papacy of Benedict XVI, all the secret societies decided to go a different way with the new pontiff.
The Freemasons were keen to start putting their new genetic engineering technology to use, and so create some kind of freakish monstrosity that would be a continued impediment to population control. They were shouted down by the Illuminati, who were excited about the possibilities of having the first artificial pope.
The Priory of Sion and the Jesuits were in agreement a change was in order, but they could not agree on doctrinal issues (though the Jesuits had half a candidate in mind); the Vril Society was totally useless, proposing it was now time to introduce their alien masters to the world in the form of a scaly lizard-like beast called Todd.
The Creeping Dread Society felt it was time for some sort of cephalopod to hold the office, and the Skull and Bones felt that this was Jeb’s time.
In the end, they opted for a mixture of approaches — with considerable help from Sony — and the first RoboPope was introduced to the world.
