Mastermold and Sentinel Army vs. Fantastic Four
If Proffessor Xavior was held captive in a slave camp on Genosha Island or somewhere in the Savage Lands by Mastermold God himself knows Cyclops will be bitching about it for hours until Logan can take it no more and does the one thing he's the best at, bother someone else.
So if the FF fell prey to the torturous villainy of the Ultimate sentinel, Mastermold and his entire army or does Proffessor Xavior simply die and have a cheap funeral? 😮💨
