Blockbuster

Here is another great character who would make an awesome secondary villain. And by that I mean that he'd be great as one of those defeated by Wolverine early in the movie. Thus, Blockbuster is incredibly strong and durable, his abilities having been enhanced by Mr. Sinister himself.

As a matter of fact, he could be a great bodyguard for Sinister. In a way, he could be the big and strong brute Wolverine has to defeat in order to reach the mastermind. Of course, if the movie will go in this direction.

In any way, if Fox does intend to adapt the Old Man Logan storyline, there are a host of super strong mutants that could be thrown in Wolverine's path. And Blockbuster should be the first one.
