Hello everyone. I am currently making a trading card game based on the DC comics universe.
If you take this any further than your own table DC Comics will serve you with a Cease & Desist order.
Why not spend just as much effort making the game on characters of your own design and then you won't be in a position to have your efforts wasted by lawyers? If you don't think you can make up your own characters, there are several characters in the public domain at your disposal. For example, this seems like something that would map very well to the Greek or Norse mythologies.
