Although I disagree with Jenn's decision to delete the article on lack of gameplay text to a small degree (you would have had a day to remedy it), the source text was plagiarised from the SNK wiki, so I would have deleted it for that reason anyway.
You don't need to ask to create articles, though we do ask that you create them in the new layout, which is similar to the old layout, except all character versions are branched into their own article so one page isn't bogged down with text and images. Pikaman is a good example of what needs doing for the source character article, while its branch is a good example of what's required for a character version article.
It's a fickle problem. I think the only real solution to this is to go by the character's base form and perhaps do separate articles for the different forms, should they exist as MUGEN characters. That does mean Goku would need to be split into Goku and Super Saiyan Goku.
As the person who sorted out the categories on the Kirby page (and a lot of other Nintendo character pages) I would like to chip in and say that the category system is a giant mess that I have been trying to clean up.
All of the categories on that page were put there because they are technically correct, seeing as we have no actual documentation in relation to categories and I was merely working off of what seemed the most logical solution; the Mega Man category is similar in the technicalities of what weapons and elemental powers he uses in his source games (due to my unfamiliarity with the series, a good hour was spent trying to datamine the Mega Man Knowledge Base).
The problem that arises with the base form limitation is the question of 'what qualifies as the character's base form?' Kirby may only be a Wind Element User in his source game base form, but what about Smash Bros. where he's also a Hammer user (side-b), Sword User (up-b, final smash) and an Ice Element User (custom regular-b) in his base form?
