"Character Role" tags probably wouldn't be the best because A) there's a monumental amount of submissions that would require retagging, B) it wouldn't be a popular tag, most would just tag "Zelda" and be done with it. Maybe it has some utility for stories, but for images, it's just redundant.
If this thread is about retagging projects in general:
For character tags, it would be helpful to change some of them over to Character_(Series) for any character who is only known by a single/first name, AND has a name shared with characters from other media, or a name that is generic enough to confuse with something else.
Say: "Marie_(Splatoon)" and "Marie_(Skullgirls)" or "Jinx_(Teen Titans)" and "Jinx_(League of Legends)".
Eliminating confusing "multiple prey" tags would be a vast improvement, tags like f/fffm and m/ffffff are unnecessary, and should be replaced with several tags so that they show up in as generic a search as possible, they should all follow a format like: f/f, f/m, f/multiple etc - as far as tags go it's unimportant how many of each sex is consumed.
