Naming Fictional Characters

Personally (and I stress personally because it's by no means any kind of standard), I think it makes sense to use the better known name as the name of a topic. I apply this principle to real people as well as fictional characters. Additional names can always be added as topic aliases ("also known as").

There's a practical side to it. People are more likely to talk about (and search for) "Spider-Man", "Mark Twain", and "Sting" by these names, than by the lesser known "Peter Parker", " Samuel Clemens", and "Gordon Sumner". There's less information associated with the lesser known names. As an unfair example, I just searched for music on Amazon using "Gordon Sumner", and not surprisingly none of Sting's well-known albums showed up.

IMO, all egos deserve their own topic pages. How about something like an identity type with an alter ego property that links multiple identities? "Primary identity" would then be determined through other properties and the purpose of the declaration. This would allow Batman to have properties that are distinct from those of Bruce Wayne but they are still linked through an informative property.

Batman is a good case. Many of his story lines focus on whether Batman or Bruce Wayne is the primary identity. Both could be considered "secret identities". One is a caped crusader, the other is a public figure and never the 'tween shall meet (except in the Bat Cave, which is neutral ground). 

I would not attribute Batman as the owner of Wayne Industries. Whether or not Bruce Wayne could be considered a superhero or detective is a matter of debate.

On the flip side, citizens of Gotham are curious about the secret identity of Batman and they don't know to be curious about a secret identity of Bruce Wayne. 

Sting is an interesting case.. I don't really see Sting as an alter ego of Gordon Sumner. Sting is just a pseudonym/alias. Compare that situation to the acting roles that Sting/Sumner has played in film and television.

There are some superheroes that have multiple “primary identities”, and some “primary identities” have donned the costumes of multiple superheroes. Does the model handle those cases? It sort of does but not that well. See Batman vs Batman vs. Batman. Maybe addressing these situations could help refine the model.

Correct me if I'm wrong, but isn't "an identity type with an alter ego property that links multiple identities" essentially what duck1123's types do?

One "primary identity" with multiple superhero identities seems pretty straightforward: see Barbara Gordon. But the more complicated issue is when one superhero identity is assumed by multiple people. Is the Batman of "Batman Beyond" (Bruce Wayne's son in that continuity) really the same as the original Batman? And is either the same as the Batman persona assumed by Jean-Paul Valley while Batman/Wayne was temporarily out of commission?

The question of alternate-Earth Batmen seems more straightforward -- different characters with different alternate identities. So the alternate Batmen would have alternate identies of Earth-One Bruce Wayne and Earth-Two Bruce Wayne as appropriate.

I agree that pseudonyms are different than this. I think Faye's suggestion was simply that common use should determine the topic name, which I think is the right answer if we use the simpler model. But I'm inclined toward the alteregos model if we think it can work.

duck1123's types sort of do this but their names have are somewhat subjective (e.g., "primary") and therefore not as useful as they could be. Also see the third linked Batman topic. That redundant topic has an "Alternate persona" type that contains info that should really be linked to the first Batman topic but can't because that one is attributed with Bruce Wayne characteristics.

I prefer the way that Barbara Gordon is described compared to the way that Batman is described. For the most part, Barbara Gordon is a character that is distinct from Catwoman and Oracle but linked to them through alternate identies.  I would just rename "Primary identity" to "Identity". 

Primary identity is important in terms of who is most commonly associated with the other identity. There should be a way to distinquish that Bruce Wayne is the primary identity of Batman and not Jean-Paul Valley. However, that info  may be better pulled from the data in terms of # of story lines or similar value.  For example, who is the primary identity of Witchblade throughout history?
