Right now, Marvel is gearing up for another of their company-wide crossover events, focused on the Inhumans, in which they plan to reveal that there were way more people descended from the original Inhumans than originally believed. In doing this, Marvel gives themselves room to essentially reinvent the idea of
mutants in their comic universe.
Why would this matter to Marvel Studios? Well, one of the few outstanding deals in place that seems to be frustrating them at this point is 20th Century Fox's ownership of all things related to "
X-Men,"
including the word "mutant."
