Wow - Disney bashing on the Disney mailing list :o)

Are there other non-Disney characters which appeared in Disney comics or
movies? I rememember some pages of William Van Horn's creator owned "Nervous
Rex" (http://www.nervousrex.de) in the U.S. digest sized "Disney
Adventures". Do you know more examples?
