He's violating the rules by being related to a canon character, as you've put him down as Juushirou Ukitake's brother.
" Cannot be directly related to a canon or filler character whatsoever. (ie. I can have a Kuchiki character, but it can not be stated that he is related to Byakuya, Rukia, or any canon or filler character from that clan.)"
Please reconcile this issue before your character can be assessed.
However, if I'm making her an Ukitake, how can I make a good personality and history section, (especially the latter), without discussing, in depth, her relationship with her siblings, especially Jushiro?
Why does her siblings need to be Jushiro's siblings? Are you implying the Ukitake Clan only has those among its current generation? My point is, it can't be outright expressed. Any Ukitake member could be considered a cousin of Jushiro, and thus related to him, but you can't actually point that out on the article, you have to pretend that connection doesn't exist or isn't relevant. Like how almost any Kuchiki member could be considered Byakuya's uncle, or cousin, or something, but it isn't outright stated, it's left solely to speculation by the reader.
"how can I make a good personality and history section, (especially the latter), without discussing, in depth, her relationship with her siblings, especially Jushiro? "
To answer this question, that's generally what the Relationships section is for. It is best not to describe a character's personal relationships in excessive detail in the two sections you mentioned (especially History, since that's technically going off-topic), although mentioning them is okay when necessary.
Anyway, I'll reserve my review of the character until the issues are resolved and edit it accordingly afterwards, since I'm already working on it.
I'm putting my foot down when it comes to stuff like this. You can't just put down a name and a couple of headers, and call it good to go. And then make ten of them every day, thinking you can just leave them as clutter until it suits your fancy to work on them. Add some content to your other characters BEFORE making new character pages, or else I'm going to treat this like vandalism next time and you'll be blocked for a week.
Just a question regarding this, while I certainly have seen many of these empty articles that has no content whatsoever, I have also seen articles that are under construction such as ones that my friends have made some and some that I have created myself. These articles are typically filled out over the course of a couple of days to say, a week after they're posted, so would these articles also be considered the same as these empty articles, or will they be accepted as long as work is being put into them?
It's different when there is SOME content put there and empty sections left for another time. I have articles like that myself. But Pitz here is making character articles without infoboxes, opening paragraphs, nothing. Just a bunch of section titles, that's all. And he's making almost ten of them every single day or two. That is considered clutter, and was already directly warned of this when Ten deleted a bunch of them beforehand.
You can't think of an article name and put a reserve on it. Other people might want that title themselves and actually KNOW what to write when they make it, so this kind of thing can't be tolerated.
So, you should probably check to see who leaves messages on talk pages so you don't end up spamming the same poor person's wall. ;)
1. The headings haven't been fixed, now they're just one huge block of text. Make sure you put each section in a different paragraph, and bold the headings.
Like This- (put the info here)
Shunpo- blah blah blah
Etcetera- Blah blabbity blah blah
THIS is the Manual of Style for this Wiki, and you need to read it. It doesn't take that long. So... yeah, read it.
2. The links I left on the talk page explain why Seke is a rip-off of Ichigo. Please look through them. Basically, it's called god-modding. Sure, Shinigami ARE gods, but that doesn't mean your character should be more powerful than even the MAIN CHARACTER in the series. Seireitou's a very bad example for giving characters way too much power, so don't follow what he does. (no worries Sei-sama, ;) ) But what he said on Mangetsu's wall is something you should pay attention too. His characters (for the most part) have themes. Which leads mean into:
3. Pick one. It's a good idea to make your character a hollow OR a shinigami OR a ____ whatever, but don't mix them all together into one thing. Again, this is just copying Ichigo. It doesn't add any depth to the character, nor does it automatically make him "cool." Cool characters, are mostly about, well, character. If Seke has a unique and unforgettable character (meaning the way he speaks and acts) then people are going to remember him and like him. Which is something they won't do just by slapping a bunch of random powers on him willy-nilly. Believe it or not, the more powerful your character is, the less interesting the fights actually become. Story is about conflict, and weakness creates conflict. It's a good thing to have, and something you should give Seke. He can't be good in every area. Everyone has limitations. So unify the article, choose ONE theme and stick with it. Get rid of excess "paper" powers and try to define who this guy really is, underneath the skin.
That should be alright since there happen to be the same things in canon. (Vizords.) Just make sure you specify that that's what he is, and maybe try to give him a history that explains how he became one.
