The evil doer will eradicate all the heroes once he gets his hands on the power source so he must be stopped at any rate. All the heroes join hands and some of the villains also form new alliances for the ultimate goal. It is like the clash of the titans and survival is surely the first thing for everyone. Alex Irvine has surprises in X-Men: Days of Future Past and Pacific Rim Uprising too if you are interested in fantasy things.
War or the ultimate competition starts from the first pages of this book and it does not end as long as the competition is moving forward. Don’t skip any portion because the war and competition is in a sequence that will not provide the same spice if skipped a little.
