This my first RPG I've created.
What happens is that your hero wakes up in a place called Shadow Earth, a mysterious universe that looks like Earth except there is a strange shadow everywhere and other things that make subtly different then our own universe.
More importantly, your hero wakes up near Shadow Doppelgangers.
The Doppelgangers look just like your hero except that their powers are exactly opposite to the hero's powers and if your hero is good, the Doppelganger is evil and vice versa.
You must use your ComicVine characters.
