Sorry I was surfing my Metal Gear forum.
Umm, please don't confuse the X-Men movies with the comics. The movies are complete tripe and were only made to broaden the fan base and make money. In the Days of Future's Past it shows a Sentinel vaporizing Wolverine. I fyou have a high enough concentration of a blast Wolverine would be stripped of his flesh completely not leaving him with any to regenerate off of. Only his skelaton is covered with adamantium, which leaves every nook and cranny between the bones a weak spot for the beam to get through. Ex, his eyes aren't covered and there are open spots in your skull to lead to vaporizing his brain. As big a fan, I'm still not oblivious to the concept of reality on fiction.
