body: Suppose I want to use some character from Disney for a website offering something not related with Disney business at all (for example a service for software developers). 
  
  
  Is this OK or Disney could sue me for that? (I know this is unlikely) 
  
  
  What could be the penalty for something like that? 
  
  
  Is there any case where this could be legal? (maybe some derivative work, not original image from Disney, or maybe depending on my country?) 
  
  
  EDIT: to be clear, I have read similar questions about trademarks here, but I'm asking something different (I think). The core of the question is that the characters are not important for the business, is not like selling t-shirts or toys, is just like a decoration, maybe this is not important at all for a trademark, or maybe yes, or maybe in some conditions, that's the question.
