It is not too rare to see a fanforum eager to get their beloved character back. The newest example of this might be smashbrawl where some supposedly vital characters were missing like mewtwo, midna etc. (http://uk.stars.ign.com/articles/850/850888p2.html)
Mass emails such as http://wmb.kg13.com/site4/email.html attempt to fuse fan comments, fan art and plenty of other material together in an attempt to set their dreams alight again.
The question is does it work, do you know any examples of Characters returning from an outcry of fans?
Let's bade the Midna crew good luck!
