user111: This is going to be a very short question. Sooner or later people will start creating tags of popular characters, e.g., kurosaki-ichigo.
What should be our policy regarding them? AFAIK they are not usually allowed on SCIFI.SE, but they also have exceptions such as c3po, or spock.
Should we generally allow or forbid using such tags?

user27: I'd argue we should collectively disallow them. Even if the intention is good, things will get out of hand real quick.
Imagine the following:

"What is the relationship between Naruto, Sasuke and Sakura?"
narutonaruto-uzumakisasuke-uchihasakura-haruno

Even if you do limit to "only notable characters" or "only protagonists/antagonists", the line is far to blurred out to be used correctly.

user15: I think that usually they don't have really a reason to exist, unless

It's a very prominent character, that stands out;
There are many questions about this specific character.

For example, on SciFi, there is a voldemort tag. It is a prominent character (the main antagonist and what an antagonist!) and there are 80 questions with this tag. That makes it a good tag. There will definitely be people searching for this tag.
One single tag about character-from-anime would probably be too little. Is it really an interesting character, widely appreciated? If the question is no, it probably doesn't deserve a tag.
In any case, we don't need to take all the decisions now. I think it's best if we decide as we go on, keeping the tags we realize work and cutting those that we see have no reason to exist. But what I said will give us some parameters to decide and to anticipate what tags might work and which ones wouldn't.
