If a franchise contains multiple stories, then a villain can be both the Big Bad of the main story and the Bigger Bad of the spin-off story, as with the example of Gihren Zabi I gave above.

As the Bigger Bad page states:

'''HIGHLY IMPORTANT: A Bigger Bad can logically ONLY appear in stories with a Big Bad. A Big Bad CANNOT be a Bigger Bad at the same time, unless there is a spin-off series in which one of his servants serves as the Big Bad.'''
