Possible official titles for Batman vs. Superman

Everyone has been referring to the Man of Steel sequel simply as Batman vs Superman. It's to the point and self explanatory. However, it isn't an official title. Warner Bros. has yet to release an official title for this project and everyone has just settled on the Batman vs. Superman name. However, there is word that WB has registered 8 potential titles for the project.

Fusible claims that the studio has gone to MarkMonitor, an internet brand protection company, to register these 8 titles just in case they want to use one of them. That doesn't guarantee one of them will be used, though. Some studios do it to prevent others from marketing on their brand. Also bear in mind that most of these titles make no sense.

Man of Steel: Battle the Knight
Man of Steel: Beyond Darkness
Man of Steel: Black of Knight
Man of Steel: Darkness Falls
Man of Steel: Knight Falls
Man of Steel: Shadow of the Knight
Man of Steel: The Blackest Hour
Man of Steel: The Darkness Within


Out of the given registries, I think the best ones are Knight Falls and Shadow of the Knight. All the other ones sound gimmicky and stupid. It is also worth mentioning that including any Dark Knight reference might be frowned upon in the end because it could create confusion with Christopher Nolan's Dark Knight Trilogy. A trilogy WB has said the Man of Steel arc will have nothing to do with and will not follow. Due to that, my guesses are on any of the other titles, like The Blackest Hour, to make the final cut.

I'm still hoping for The World's Finest, but that might just be me. Whatever the title winds up being, the Man of Steel sequel is set for release on July 17, 2015.
