Well it would be interesting to give each character a page, although there are some characters that are not very well fleshed out in the show and might not really have a lot to be said about them other than say, statistics from some of the artbooks.
I'm not sure if I'm for putting it under the SciFi Universe section since, in reality it is
SciFi Anime. I think we should tread carefully and not have it turn into something like the Star Wars entry which is sort of ridiculous and leads to utterly ridiculous nonsense like THIS
which nerds should be embarrassed exists and is more fleshed out than most REAL forms of martial arts.
