I would ask that you be more cautious in your renaming topics. Both Batman and Superman are the topics of general interest, not their alternate identities Bruce Wayne and Kal-EL (aka Clark Kent). When the title of a topic is changed it greatly affects the relevence search results used for autocomplete. Once Superman was renamed to Clark Kent the relevence diminished in the scoring we use to provide matches to searches of the term Superman. The result was that the new top result would be the film Superman, then a Superman Anthology, about 5 or 6 places down would be Clark Kent topic.
Please think of it in terms of what is of the highest interest. It's great you've created a Primary Identity type, and that would be perfect for the lesser personalities of the Superheroes (and other characters both fictional and real).
I hope you have a good holiday season.
