I asked about this once before in the forums and never got any response from it, but I figure I should ask again, because it's come to mind again.
What is the wiki stance on characters such as the following?
Magoichi Saiga is a historical figure that has been depicted in a variety of games. He is also a man. That is, except for the character's appearances in the Sengoku Basara series, where the creators pulled a gender swap and made their incarnation of the historical figure a woman. The same has also occurred in the Warriors Orochi series, wherein the character Sanzang (a male character in the novel Journey to the West) is recast as female.
So what do we do here? Keep them on a single page? Make separate character pages? Is this a case for the Gender Change concept, or would a different concept be more appropriate?
