While most fans seem to still like the title of World’s Finest the best, it looks like Warner Bros. may be eyeing other titles for Zack Snyder’s Batman vs. Superman movie instead.

There’s been a lot of debate over the official title of the upcoming Batman vs. Superman film scheduled to be released in 2015. This week, Warner Bros. secretly registered a host of possible titles through the internet brand protection company MarkMonitor. Now, it’s likely the debate is going to get more opinions. According to the latest domain registrations, possible titles include “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 Night,” “Man of Steel The Blackest Hour,” and “Man of Steel The Darknness Within.”

Do you like one of these? Do you think they may be for merchandise instead? Do you think they should go with either Batman vs. Superman or World’s Finest for the title? Let us know your thoughts in the comments below.

The Man of Steel sequel, starring Henry Cavill, Ben Affleck, Amy Adams, Diane Lane and Laurence Fishburne, hits theaters on July 17, 2015.
