If he is Peter the Roman:

he will be a doctrinal Pope (like Pius 9 through 12), not a pastoral Pope

he will be the last Pope for a while to reign from Rome

he will use papal infallibility more than all his predecessors combined

he will excommunicate politicians who vote for abortion, who publicly reject infallible Catholic teaching

he will emphasize the primacy of the Roman Catholic Faith over other religions

he will reign during the start of World War 3
