The Demon (Damian Wayne).
Character belongs to DC Comics.
This isn't Earth-27 for anyone wondering - but it is inspired by the project, if you will. This is an idea I had for an older Damian adopting the codename "The Demon" after taking the leadership of the League of Assassins. Seemed like a natural progression for the character. I was toying with the idea he wouldn't wear a mask anymore at this point - but I kind of like the idea of him having one just to look cool. At this point in the future, I imagine none of the Bat-Family members have secret identities anymore. Everyone just knows who they are, and they deal with it.
