So finishing the campaign and starting Marvel Adventures I started to wonder if we had any cusom heroes (I'm also developing some fan fiction and could use some inspiration) and I was wondering if there were any skins developed that could possibly develop a story of its own
They're kind of scattered around, but there are TONS of original characters made by various members of the community.
You can find some in these places:
