Hey guys. I'm hoping I've put this in the right subforum. One of the major characters of the novel I'm working on is a young man obsessed by superhero comics, particularly The Punisher. I have mentioned him reading his way through a Punisher graphic novel as the story unfolds. Later on, through a number of events and a personality shift due to a brain injury, he becomes a murderous vigilante himself, modelling himself on The Punisher, to the point that he tells a detective over the phone that his name is Frank Castle. I was going to have him wearing The Punisher's skull motif until he develops his own persona, but I thought that may be a step too far. My question is...am I allowed to include any of this? I've become a tad worried that this may bother Marvel somewhat (I genuinely love The Punisher myself, there's a lot of me in this character). I'm aware that you are allowed to mention existing properties and brands, but here I am, making the fact that my character loves one of Marvel's most well known properties a major plot point. Even suggesting that reading these comic books has led him to do the things he's doing.
