A-Knight

After doing some digging, I figured out the password. The password is "Chihuahua" (no quotation marks)

It has been reuploaded now (udonge.sff), though it is password protected.

Hard to say, I myself have tried tracking down the author's Reisen but no luck. Though the uploader might reupload it again if I had to guess, usually they take it down to fix something. Not having a def file with the authorname included does make it more complicated (for us atleast). Judging by the sff size, it can't be a character with too many sprites.

I would've checked, but the file appears to have been taken offline anyway.

I have a backup https://www.dropbox.com/s/v6jlpxytde60pzt/sprite.rar?dl=0

The download link for her is dead and I can't seem to find her anywhere, even with Waybackmachine.

That's strange, worked fine for me atleast. Uploading her without password protection

It worked, guess it must have slipped through my eyes when I was searching for him. Posting link for him just incase someone else happens to be interested in those characters.

His onedrive appears to be dead 

She was a april fools character that was released for a limited time.

Can't seem to find him anywhere.

It looks like All Star Battle version of Jonathan is in progress.

Godspeed, Ryoucchi.

17th_star used to have characters on his baidu page, but he doesn't anymore. I do have some of his characters (Rugal_Panther, Dragon-Meiling and Crazy-Leona) but unfortunately I didn't download the rest of his characters when I had the chance. If anybody has her, please do share 

I think that might be the stage itself, not seen anything like that when I try Broly out, unless it happens for almost every stage you have.

Never mind, found it somewhere else. http://baoheapi.baidu.com/wap/link?uk=2052225872&shareid=1785381940&third=0

Mugenlist atleast says Happa made a AI patch for NashU(nkoman), but it isn't on his onedrive.

Wow.. Thank you so much!

There is one problem with Noobic Cube's AI patch for Kyoso (aum_AIPatch on his skydrive), its password protected. I can understand some authors adding password protection to their characters, but for AI? Really..

Is there a full/final version for Marona by Stupa? If not, is there any AI patch for her?

Dead skydrive link for him unfortunately..
