Zero.
Unpopular opinion: the X-men - mutants in general - don't mesh well with the rest of the Marvel universe at all... X-writers don't know how to write their stories without throwing this or that property under the bus, and it's tiring.
So, I voted 1, because there wasn't the option to vote 0, but really it's 0 for me.
Total quarantine from one another and be done with it.
