body: I'm developing a mobile application and inside it, I have some customization options. I was interested in using designs, colors and ideas based on famous cartoon characters. For example: Wolverine's claws with a yellow background, Captain America's shield, Superman's symbol, Batman's face... etc...
  
  
  So, I'd like some information about this.
  Can I use those images in the first place? What are the implications?
  
  
  I know that I can't use a full batman drawing from an artist, but how about the batman symbol (which is universally known and used everywhere). Is there a difference?
  
  
  And finally, If I do get a C&D order, can I simply remove the content and avoid any further legal implications?
  
  
  Thank you very much.
